django-dash (later on named Dash) is a customisable, modular dashboard
application framework for Django.
Dash allows users to create their own custom dashboards. Supports theeming (in Dash themes are called layouts) and multiple workspaces. Dash comes with extensive pythonic API which allows developers to create new Dash plugins, as well as to modify bundled ones.
To make a clearer association, think of Android for tablets (shortcuts, widgets and apps) or Windows 8 for tablets or desktops.
Dash inherits all those concepts and makes it possible to implement a dashboard system for Django applications with minimal efforts.

Question: Is it possible to have Dash working with a (pick what's applicable: D3, Polychart2, or some other library for making charts).
Answer: Yes. Check the source code of the following sample plugins:
Sample D3 plugins <https://github.com/barseghyanartur/django-dash/tree/master/examples/example/d3_samples>_.Sample Polychart2 plugin <https://github.com/barseghyanartur/django-dash/tree/master/examples/example/bar>_.See the documentation for some screen shots:
ReadTheDocs <http://django-dash.readthedocs.org/en/latest/#screenshots>_See the live demo app <https://django-dash.herokuapp.com/>_ on Heroku.
Credentials:
See the public dashboard of a test_demo_user <https://django-dash.herokuapp.com/en/test_demo_user/>_ to get an idea of what
it could become.
In order to be able to quickly evaluate the django-dash, a demo app (with a
quick installer) has been created (works on Ubuntu/Debian, may work on other
Linux systems as well, although not guaranteed). Follow the instructions
below for having the demo running within a minute.
Grab the latest django_dash_example_app_installer.sh:
.. code-block:: sh
wget https://raw.github.com/barseghyanartur/django-dash/stable/examples/django_dash_example_app_installer.sh
Assign execute rights to the installer and run the
django_dash_example_app_installer.sh:
.. code-block:: sh
chmod +x django_dash_example_app_installer.sh
./django_dash_example_app_installer.sh
Open your browser and test the app.
Dashboard:
Django admin interface:
If quick installer doesn't work for you, see the manual steps on running the
example project <https://github.com/barseghyanartur/django-dash/tree/stable/examples>__.
Take a look at the templates in "example/example/templates" directory for getting a better idea of how to transform your own or third-party templates into Dash templates.
Also, the example project <https://github.com/barseghyanartur/django-dash/tree/stable/examples/example/foo>__
has example layouts, plugins and widgets implemented. Take it as a good example
of how to add widgets for existing plugins to your own custom layout.
Make sure to see how same is done for the bundled layouts <https://github.com/barseghyanartur/django-dash/tree/stable/src/dash/contrib/layouts/>_.
Install latest stable version from PyPI:
.. code-block:: sh
pip install django-dash
Or latest stable version from GitHub:
.. code-block:: sh
pip install https://github.com/barseghyanartur/django-dash/archive/stable.tar.gz
Or latest stable version from BitBucket:
.. code-block:: sh
pip install https://bitbucket.org/barseghyanartur/django-dash/get/stable.tar.gz
Add dash to INSTALLED_APPS of the your projects' Django settings.
Furthermore, all layouts and plugins to be used, shall be added to the
INSTALLED_APPS as well.
.. code-block:: python
INSTALLED_APPS = (
# ...
'dash',
'dash.contrib.layouts.android',
'dash.contrib.layouts.bootstrap2',
'dash.contrib.layouts.windows8',
'dash.contrib.plugins.dummy',
'dash.contrib.plugins.image',
'dash.contrib.plugins.memo',
'dash.contrib.plugins.rss_feed',
'dash.contrib.plugins.url',
'dash.contrib.plugins.video',
'dash.contrib.plugins.weather',
# ...
)
Make sure that django.core.context_processors.request is in
TEMPLATE_CONTEXT_PROCESSORS.
Add necessary URL patterns to your urls module.
.. code-block:: python
re_path(r'^dashboard/', include('dash.urls')),
Additionally, add all URLs of any Dash apps or plugins
.. code-block:: python
# django-dash RSS contrib plugin URLs:
re_path(r'^dash/contrib/plugins/rss-feed/',
include('dash.contrib.plugins.rss_feed.urls')),
# django-dash public dashboards contrib app:
re_path(r'^', include('dash.contrib.apps.public_dashboard.urls')),
Dash comes with several bundled layouts. Do check their source code as example.
Let's say, our imaginary layout has two placeholders. One large placeholder for
all kinds of widgets (called main) and a tiny one for shortcuts (called
shortcuts).
Placeholder main:
Placeholder shortcuts:
See the figure below to get an idea of what placeholders are:
main consts of cells from 11 to 56.shortcuts consists of cells from 1 to 10.A single plugin widget may occupy one or more cells. Plugin widgets are rectangles.
To make it clear, see following cases:
.. code-block:: text
``main`` ``shortcuts``

There are some rules/guidelines you should follow.
Let's assume that layout is named example. The layout directory should then
have the following structure.
.. code-block:: text
path/to/layout/example/
├── static
│ ├── css
│ │ └── dash_layout_example.css # Contains layout-specific CSS
│ ├── images
│ └── js
│ └── dash_layout_example.js # Contains layout specific JavaScripts
├── templates
│ └── example
│ ├── edit_layout.html # Master edit layout
│ └── view_layout.html # Master view layout
├── __init__.py
├── dash_layouts.py # Where layouts and placeholders are defined and registered
├── dash_plugins.py # Where layout specific plugins and plugin widgets are defined and registered
└── dash_widgets.py # Where layout specific plugin widgets are defined
Layout and placeholder classes should be placed in the dash_layouts.py
file.
Each layout should be put into the INSTALLED_APPS of your Django projects'
settings.py module.
.. code-block:: python
INSTALLED_APPS = (
# ...
'path.to.layout.example',
# ...
)
Step by step review of a how to create and register a layout and placeholders.
Note, that Dash auto-discovers your layouts by name of the file
dash_layouts.py. The module, in which the layouts are defined, has to be
named dash_layouts.py.
Required imports.
.. code-block:: python
from dash.base import BaseDashboardLayout, BaseDashboardPlaceholder
from dash.base import layout_registry
Defining the Main placeholder.
.. code-block:: python
class ExampleMainPlaceholder(BaseDashboardPlaceholder):
uid = 'main' # Unique ID of the placeholder.
cols = 6 # Number of columns in the placeholder.
rows = 5 # Number of rows in the placeholder.
cell_width = 150 # Width of a single cell in the placeholder.
cell_height = 110 # Height of a single cell in the placeholder.
Defining the Shortcuts placeholder.
.. code-block:: python
class ExampleShortcutsPlaceholder(BaseDashboardPlaceholder):
uid = 'shortcuts' # UID of the placeholder.
cols = 1 # Number of columns in the placeholder.
rows = 10 # Number of rows in the placeholder.
cell_width = 60 # Width of a single cell in the placeholder.
cell_height = 55 # Height of a single cell in the placeholder.
Defining and registering the Layout.
.. code-block:: python
class ExampleLayout(BaseDashboardLayout):
uid = 'example' # Layout UID.
name = 'Example' # Layout name.
# View template. Master template used in view mode.
view_template_name = 'example/view_layout.html'
# Edit template. Master template used in edit mode.
edit_template_name = 'example/edit_layout.html'
# All placeholders listed. Note, that placeholders are rendered in the
# order specified here.
placeholders = [ExampleMainPlaceholder, ExampleShortcutsPlaceholder]
# Cell units used in the entire layout. Allowed values are: 'px',
# 'pt', 'em' or '%'. In the ``ExampleMainPlaceholder`` cell_width is
# set to 150. It means that in this particular case its' actual width
# would be `150px`.
cell_units = 'px'
# Layout specific CSS.
media_css = ('css/dash_layout_example.css',)
# Layout specific JS.
media_js = ('js/dash_layout_example.js',)
# Registering the layout.
layout_registry.register(ExampleLayout)
You custom layout should be inherited from base layout templates (view or edit). Both view and edit layouts share a lot of things, still edit layout is a bit more "heavy".
Both "dash/layouts/base_view_layout.html" and "dash/layouts/base_edit_layout.html" inherit from "dash/layouts/base_layout.html", which in its' turn inherits from "dash/base.html".
Note, that when rendered to HTML, each Dash template, gets a body class
"layout" + layouts' unique identifier (UID). So, the ExampleLayout
layout would automatically get the class "layout-example".
.. code-block:: html
<body class="layout-example">
In case of Android layout (UID "android") it would be as follows.
.. code-block:: html
<body class="layout-android">
Base your layout specific custom CSS on presence of those classes.
Same goes for Placeholders. Each placeholder gets id_ + placeholders' UID
and the classes "placeholder" and "placeholder-" + placeholders' UID. So, the
ExampleMainPlaceholder would look as follows.
.. code-block:: html
<div id="id_main" class="placeholder placeholder-main">
And the ExampleShortcutsPlaceholder placeholder would look as follows.
.. code-block:: html
<div id="id_shortcuts" class="placeholder placeholder-shortcuts">
Same goes for plugin widgets. Apart from some other classes that each plugin widget would get for positioning, it gets the "plugin" and "plugin-" + plugin UID. See the following example (for the plugin Dummy with UID "dummy"). Each plugin also gets an automatic UID on the moment when rendered. In the example below it's the "p6d06f17d-e142-4f45-b9c1-893c38fc2b01".
.. code-block:: html
<div id="p6d06f17d-e142-4f45-b9c1-893c38fc2b01" class="plugin plugin-dummy">
Layout, placeholder, plugin and plugin widget have properties for getting their HTML specific classes and IDs.
Layout (instance)
.. code-block:: python
layout.html_class
Placeholder (instance)
.. code-block:: python
placeholder.html_id
placeholder.html_class
Plugin (instance)
.. code-block:: python
plugin.html_id
plugin.html_class
Plugin widget (static call)
.. code-block:: python
plugin_widget.html_class # Static one
Dash comes with several bundled plugins. Do check their source code as example.
Making of a plugin or a plugin widget is quite simple, although there are some rules/guidelines you should follow.
Let's assume that plugin is named sample_memo. The plugin directory should
then have the following structure.
Note, that you are advised to prefix all your plugin specific media files
with dash_plugin_ for the sake of common sense.
.. code-block:: text
path/to/plugin/sample_memo/
├── static
│ ├── css
│ │ └── dash_plugin_sample_memo.css # Plugin specific CSS
│ ├── images
│ └── js
│ └── dash_plugin_sample_memo.js # Plugin specific JavaScripts
├── templates
│ └── sample_memo
│ ├── render_main.html # Plugin widget template for ``main`` Placeholder
│ └── render_short.html # Plugin widget template for ``shortcuts`` Placeholder
├── __init__.py
├── dash_plugins.py # Where plugins and widgets are defined and registered
├── dash_widgets.py # Where the plugin widgets are defined
└── forms.py # Plugin configuration form
In some cases, you would need plugin specific overridable settings (see
dash.contrib.plugins.weather plugin as an example. You are advised to
write your settings in such a way, that variables of your Django projects'
settings.py module would have DASH_PLUGIN_ prefix.
Step by step review of a how to create and register a plugin and plugin
widgets. Note, that Dash auto-discovers your plugins if you place them into a
file named dash_plugins.py of any Django app listed in INSTALLED_APPS
of your Django projects' settings module.
Define and register the plugin
As already stated, a single plugin widget is registered for a triple (layout,
placeholder, plugin). That means, that if you need two widgets, one sized 1x1
and another sized 2x2, you need two plugins for it. You can either manually
define all plugins and widgets for the sizes desired, or define a single
base plugin or a widget class and have it factory registered for a number of
given sizes. Below, both approaches would be explained.
Required imports.
.. code-block:: python
from dash.base import BaseDashboardPlugin, plugin_registry
from path.to.plugin.sample_memo.forms import SampleMemoForm
Defining the Sample Memo plugin (2x2) (to be used in the ``main`` placeholder).
.. code-block:: python
class SampleMemo2x2Plugin(BaseDashboardPlugin):
uid = 'sample_memo_2x2' # Plugin UID
name = _("Memo") # Plugin name
group = _("Memo") # Group to which the plugin belongs to
form = SampleMemoForm # Plugin forms are explained later
html_classes = ['sample-memo'] # Optional. Adds extra HTML classes.
Registering the Sample Memo plugin.
.. code-block:: python
plugin_registry.register(SampleMemo2x2Plugin)
Defining the Sample Memo plugin (1x1) (to be used in the ``shortcuts``
placeholder).
.. code-block:: python
class SampleMemo1x1Plugin(SampleMemo2x2Plugin):
uid = 'sample_memo_1x1' # Plugin UID
Registering the Sample Memo plugin.
.. code-block:: python
plugin_registry.register(SampleMemo1x1Plugin)
Repeat the steps below for each plugin size (or read about factory registering
the plugins and widgets below).
Factory register plugins
~~~~~~~~~~~~~~~~~~~~~~~~
Alternatively, you can define just a single plugin base class and have it
factory registered for the given sizes. The code below would produce and
register classes for in sizes 1x1 and 2x2. When you need to register a plugin
for 10 sizes, this approach clearly wins. Besides, it's very easy to get a
clear overview of all plugins sizes registered.
Required imports.
.. code-block:: python
from dash.base import BaseDashboardPlugin
from dash.factory import plugin_factory
from path.to.plugin.sample_memo.forms import SampleMemoForm
Defining the base plugin class.
.. code-block:: python
class BaseSampleMemoPlugin(BaseDashboardPlugin):
name = _("Memo") # Plugin name
group = _("Memo") # Group to which the plugin belongs to
form = SampleMemoForm # Plugin forms are explained later
html_classes = ['sample-memo'] # Optional. Adds extra HTML classes.
Note, that we don't provide ``uid`` property in the base class.
Now, that we have the base plugin defined, factory register it for the sizes
given.
.. code-block:: python
sizes = (
(1, 1),
(2, 2),
)
plugin_factory(BaseSampleMemoPlugin, 'sample_memo', sizes)
In the example above, "sample_memo" is the base name of the plugin. Size
information would be appended to it ("sample_memo_1x1", "sample_memo_2x2").
Register plugin widgets
~~~~~~~~~~~~~~~~~~~~~~~
Plugin widgets are defined in ``dash_widgets.py`` module (described later), but
registered in the ``dash_plugins.py``, which is auto-discovered by Dash.
Required imports.
.. code-block:: python
from dash.base import plugin_widget_registry
from path.to.plugin.sample_memo.dash_widgets import (
SampleMemo1x1ExampleMainWidget,
SampleMemo2x2ExampleMainWidget,
)
Registering the Sample Memo plugin widget for placeholder ``main`` of layout
`example``.
.. code-block:: python
plugin_widget_registry.register(SampleMemo2x2ExampleMainWidget)
Registering the Sample Memo plugin widget for placeholder ``shortcuts`` of
layout ``example``.
.. code-block:: python
plugin_widget_registry.register(SampleMemo1x1ExampleMainWidget)
path/to/plugin/sample_memo/dash_widgets.py
------------------------------------------
Why to have another file for defining widgets? Just to keep the code clean and
less messy, although you could perfectly define all your plugin widgets in the
module ``dash_plugins.py``, it's recommended to keep it separate.
Take into consideration, that ``dash_widgets.py`` is not an auto-discovered
file pattern. All your plugin widgets should be registered in modules named
``dash_plugins.py``.
Define and register the plugin widget
Required imports.
.. code-block:: python
from django.template.loader import render_to_string
from dash.base import BaseDashboardPluginWidget
Memo plugin widget for Example layout (placeholder main).
.. code-block:: python
class SampleMemo2x2ExampleMainWidget(BaseDashboardPluginWidget):
layout_uid = 'example' # Layout for which the widget is written
placeholder_uid = 'main' # Placeholder within the layout for which
# the widget is written
plugin_uid = 'sample_memo_2x2' # Plugin for which the widget is
# written
cols = 2 # Number of widget columns
rows = 2 # Number of widget rows
def render(self, request=None):
context = {'plugin': self.plugin}
return render_to_string('sample_memo/render_main.html', context)
Memo plugin widget for Example layout (placeholder shortcuts).
.. code-block:: python
class SampleMemo1x1ExampleShortcutWidget(SampleMemo2x2ExampleMainWidget):
placeholder_uid = 'shortcuts' # Placeholder within the layout for
# which the widget is written
cols = 1 # Number of widget columns
rows = 1 # Number of widget rows
def render(self, request=None):
context = {'plugin': self.plugin}
return render_to_string(
'sample_memo/render_shortcuts.html', context
)
Factory register plugin widgets
Alternatively, you can define just a single plugin widget base class and have
it factory registered for the given sizes. The code below would produce and
register classes for in sizes 1x1 and 2x2.
Required imports.
.. code-block:: python
from django.template.loader import render_to_string
from dash.factory import plugin_widget_factory
from dash.base import BaseDashboardPluginWidget
Defining the base plugin widget class.
.. code-block:: python
class BaseSampleMemoWidget(BaseDashboardPluginWidget):
def render(self, request=None):
context = {'plugin': self.plugin}
return render_to_string('sample_memo/render.html', context)
Now, that we have the base plugin defined, factory register it for the sizes
given.
.. code-block:: python
sizes = (
(1, 1),
(2, 2),
)
plugin_widget_factory(
BaseSampleMemoWidget, 'example', 'main', 'sample_memo', sizes
)
In the example above:
- "sample_memo" is the base name of the plugin and it should match the name
given to plugin factory exactly.
- "example" is the uid of the layout, for which the widget is being registered.
- "main" is the uid of the placeholder, for which the widget it being
registered.
path/to/plugin/sample_memo/forms.py
-----------------------------------
What are the plugin forms? Very simple - if plugin is configurable, it has a
form. If you need to have a custom CSS or a JavaScript included when rendering
a specific form, use Django's class Media directive in the form.
Required imports.
.. code-block:: python
from django import forms
from dash.base import DashboardPluginFormBase
Memo form (for `Sample Memo` plugin).
.. code-block:: python
class SampleMemoForm(forms.Form, DashboardPluginFormBase):
plugin_data_fields = [
("title", ""),
("text", "")
]
title = forms.CharField(label=_("Title"), required=False)
text = forms.CharField(label=_("Text"), required=True,
widget=forms.widgets.Textarea)
def __init__(self, *args, **kwargs):
super(MemoForm, self).__init__(*args, **kwargs)
Now, that everything is ready, make sure your that both layout and the plugin
modules are added to ``INSTALLED_APPS`` for your projects' Django ``settings.py``
module.
.. code-block:: python
INSTALLED_APPS = (
# ...
'path.to.layout.example',
'path.to.plugin.sample_memo',
# ...
)
After it's done, go to terminal and type the following command.
.. code-block:: sh
./manage.py dash_sync_plugins
If your HTTP server is running, you would then be able to access your dashboard.
- View URL: http://127.0.0.1:8000/dashboard/
- Edit URL: http://127.0.0.1:8000/dashboard/edit/
Note, that you have to be logged in, in order to use the dashboard. If your new
plugin doesn't appear, set the ``DASH_DEBUG`` to True in your Django's local
settings module (`local_settings.py`), re-run your code and check console for
error notifications.
Plugin and widget factory
=========================
In general, when making a new plugin, base widgets are made for then too. By
creating base widgets you avoid duplication of the code. See the example below.
.. code-block:: python
from dash.base import BaseDashboardPlugin
class BaseMemoPlugin(BaseDashboardPlugin):
name = _("Memo")
group = _("Memo")
form = MemoForm
Now that we have the base plugin, we can use plugin factory to generate and
register plugin classes of the required dimensions.
.. code-block:: python
from dash.factory import plugin_factory
plugin_factory(BaseMemoPlugin, 'memo', ((5, 6), (6, 5), (6, 6)))
The code above will generate "memo_5x6", "memo_6x5" and "memo_6x6" plugin
classes which subclass the ``BaseMemoPlugin`` and register them in the plugin
registry. The ``uid`` property would be automatically generated.
Same goes for the widgets.
.. code-block:: python
from dash.base import BaseDashboardPluginWidget
class BaseMemoWidget(BaseDashboardPluginWidget):
def render(self, request=None):
context = {'plugin': self.plugin}
return render_to_string('memo/render.html', context)
Now that we have the base widget, we can use plugin widget factory to generate
and register plugin widget classes of the required dimensions.
.. code-block:: python
from dash.factory import plugin_widget_factory
plugin_widget_factory(
BaseMemoWidget,
'bootstrap2_fluid',
'main',
'memo',
((5, 6), (6, 5), (6, 6))
)
The code above will generate "memo_5x6", "memo_6x5" and "memo_6x6" plugin
widget classes which subclass the ``BaseMemoWidget`` and register them in the
plugin widget registry. The ``layout_uid``, ``placeholder_uid``,
``plugin_uid``, ``cols`` and ``rows`` properties would be automatically
generated.
Of course, there would be cases when you can't use factory, for example because
each of your plugins or widgets differs from others by tiny important bits, but
if you notice yourself subclassing the base widget or plugin many times without
any change to the code, then it's perhaps a right time to start using the
factory.
Layout, plugin and widget summary
=================================
When making your own layouts, plugins and plugin widgets you are free to use
the API as you wish. While developing the Dash, I found the follow practices
useful:
- When making a new plugin, always make a base plugin class, from which all
size specific ones would derive.
- Do create base plugin widgets (with HTML templates) in the plugin, but do not
register them there. Use factory (``dash.factory``) to generate and register
layout specific plugin widgets - preferably in the layout module.
- If you're adding custom plugin to existing bundled layout (those that
reside in ``dash.contrib.layouts``), create a new module named
``dash_custom`` (or any other name that you prefer) and factory
generate/register your layout specific plugin widgets in a module named
``dash_plugins.py`` (do not forget to add the module to ``INSTALLED_APPS``,
so that it auto-discovered).
Permissions
===========
Plugin system allows administrators to specify the access rights to every
plugin. Dash permissions are based on Django Users and User Groups. Access
rights are manageable via Django admin (/administration/dash/dashboardplugin/).
Note, that your admin URL prefix may vary from the one given in example (it's
usually "/admin/", while in example it's "/administration/"). If user doesn't
have the rights to access plugin, it doesn't appear on his dashboard even if
has been added to it (imagine, you have once granted the right to use the news
plugin to all users, but later on decided to limit it to Staff members group
only). Note, that superusers have access to all plugins.

Management commands
===================
There are several management commands.
- ``dash_find_broken_dashboard_entries``. Find broken dashboard entries that
occur when some plugin which did exist in the system, no longer exists.
- ``dash_sync_plugins``. Should be ran each time a new plugin is being added
to the Dash.
- ``dash_update_plugin_data``. A mechanism to update existing plugin data in
case if it had become invalid after a change in a plugin. In order for it
to work, each plugin should implement and ``update`` method, in which the
data update happens.
Tuning
======
There are number of Dash settings you can override in the `settings.py` module
of your Django project:
- ``DASH_RESTRICT_PLUGIN_ACCESS`` (bool): If set to True, (Django) permission
system for dash plugins is enabled. Defaults to True. Setting this to False
makes all plugins available for all users.
- ``DASH_ACTIVE_LAYOUT`` (str): Active (default) layout UID. Defaults to
"android".
- ``DASH_LAYOUT_CELL_UNITS`` (str): Allowed values for layout cell units.
Defaults to ("em", "px", "pt", "%").
- ``DASH_DISPLAY_AUTH_LINK`` (bool): If set to True, the log out link is shown
in the Dash drop-down menu. Defaults to True.
For tuning of specific contrib plugin, see the docs in the plugin directory.
Styling tips
============
Font Awesome is used for icons. As a convention, all icons of font-awesome are
placed within a span. Next to their original class, they all should be getting
an extra class "iconic". Follow that rule when making a new layout or a
plugin (HTML). It allows to make the styling easy, since icon colours could be
then changed within no time.
Bundled plugins and layouts
===========================
Dash ships with number of bundled (demo) plugins and layouts that are mainly
made to demonstrate its' abilities. In order to work among various layouts
(themes), each plugin has a single widget registered for a single layout.
It's possible to unregister a bundled widget and replace it with a custom one.
Bundled plugins
---------------
Below a short overview of the plugins. See the README.rst file in directory
of each plugin for details.

8 cols x 1 rows, each block sized 55x55 px), left (3 col x 8 rows, each
block sized 55x55 px) and main (5 col x 4 rows, each block sized 110x95 px).
Naming conventions
==================
Although you are free to name your plugins and widgets as you want (except that
you should comply with `PEP-008
<http://www.python.org/dev/peps/pep-0008/#function-names>`_), there are some
naming conventions introduced, that you are recommended to follow.
- Example1x1Plugin: 1x1 example plugin
- Example1x1AndroidMainWidget: 1x1 widget for 1x1 example plugin (layout
Android, placeholder 'main')
- Example1x1AndroidShortcutsWidget: 1x1 widget for 1x1 example plugin (
layout Android, placeholder 'shortcuts')
- Example1x1Windows8MainWidget: 1x1 widget for 1x1 example plugin (layout
Windows 8, placeholder 'main')
- Example1x1Windows8SidebarWidget: 1x1 widget for 1x1 example plugin (
layout Windows 8, placeholder 'sidebar')
- Example2x3Plugin: 2x3 example plugin
- Example2x3Windows8MainWidget: 2x3 widget for 2x3 example plugin (layout
Windows 8, placeholder 'main')
- Example2x3Windows8SidebarWidget: 2x3 widget for 2x3 example plugin (
layout Windows 8, placeholder 'sidebar')
- Example6x1Plugin: 6x1 example plugin
- Example6x1YourLayoutSidebarWidget: 6x1 widget for 6x1 example plugin (
layout Your Layout, placeholder 'main')
Debugging
=========
Most of the errors are logged (DEBUG). If you have written a plugin and it
somehow doesn't appear in the list of available plugins, do run the following
management command:
.. code-block:: sh
./manage.py dash_sync_plugins
The ``dash_sync_plugins`` not only syncs your plugins into the database, but
also is a great way of checking for possible errors.
Available translations
======================
- Dutch (core and plugins)
- Russian (core and plugins)
Troubleshooting
===============
- If you somehow get problems installing ``Dash``, check the `example
<https://github.com/barseghyanartur/django-dash/tree/master/examples>`__
project and the `requirements.txt
<https://raw.githubusercontent.com/barseghyanartur/django-dash/master/examples/requirements/latest.txt>`__.
Testing
=======
Project is covered by test (functional- and browser-tests).
Py.test is used as a default test runner.
To test with all supported Python/Django versions type:
.. code-block:: sh
tox
To test against specific environment, type:
.. code-block:: sh
tox -e py35-django18
To test just your working environment type:
.. code-block:: sh
./runtests.py
To tests just your working environment (with Django test runner) type:
.. code-block:: sh
./manage.py test dash
It's assumed that you have all the requirements installed. If not, first
install the test requirements:
.. code-block:: sh
pip install -r examples/requirements/test.txt
Browser tests
-------------
For browser tests you may choose between (headless) Firefox or (headless)
Chrome. Going headless is faster, but normal browser tests tell you more (as
you see what exactly happens on the screen). Both cases require some effort
and both have disadvantages regarding the installation (although once you have
them installed they work perfect).
Set up Firefox
~~~~~~~~~~~~~~
1. Download the latest version of geckodriver
("geckodriver-vX.XX.X-linux64.tar.gz") from `this location
<https://github.com/mozilla/geckodriver/releases>`__
and unpack it somewhere (```tar -xvzf geckodriver-vX.XX.X-linux64.tar.gz```).
Then give executable permissions to geckodriver (```chmod +x geckodriver```)
move the geckodriver binary to ``/usr/local/bin`` or any location on your
system PATH.
2. Specify the full path to your Firefox in ``FIREFOX_BIN_PATH``
setting. Example:
.. code-block:: python
FIREFOX_BIN_PATH = '/usr/lib/firefox/firefox'
If you set ``FIREFOX_BIN_PATH`` to None, system Firefox would be used.
After that your Selenium tests would work.
Set up headless Firefox
~~~~~~~~~~~~~~~~~~~~~~~
1. Install ``xvfb`` package which is used to start Firefox in headless mode.
.. code-block:: sh
sudo apt-get install xvfb
2. Run the tests using headless Firefox.
.. code-block:: sh
./scripts/runtests.sh
Or run tox tests using headless Firefox.
.. code-block:: sh
./scripts/tox.sh
Setup Chrome
~~~~~~~~~~~~
1. Download the latest version of chromedriver
("chromedriver_linux64.zip") from `this location
<https://chromedriver.chromium.org/downloads>`__
and unpack it somewhere. Then give executable permissions to chromedriver
(```chmod +x chromedriver```)
move the chromedriver binary to ``/usr/local/bin`` or any location on your
system PATH.
2. Specify the full path to your Firefox in ``CHROME_DRIVER_EXECUTABLE_PATH``
setting. Example:
.. code-block:: python
CHROME_DRIVER_EXECUTABLE_PATH = '/usr/bin/chromedriver'
Set up headless Chrome
~~~~~~~~~~~~~~~~~~~~~~
.. code-block:: python
from selenium import webdriver
CHROME_DRIVER_OPTIONS = webdriver.ChromeOptions()
CHROME_DRIVER_OPTIONS.add_argument('-headless')
CHROME_DRIVER_OPTIONS.add_argument('-no-sandbox')
CHROME_DRIVER_OPTIONS.set_capability('chrome.binary', "/usr/bin/google-chrome")
CHROME_DRIVER_EXECUTABLE_PATH = '/usr/bin/chromedriver'
After that your Selenium tests would work.
