Configuration

Inline editing feature

---

Inline editing allows editors to directly click on a text plugin and change the contents in django CMS' edit mode. The CKEditor appears directly around the text field and can be used normally. Changes are saved as soon as the text field leaves focus.

Inline editing requires to encapsulate the HTML text in a <div> in edit mode. This might cause some side effects with a site's CSS, e.g. direct child rules.

To activate inline editing add the following line in your project's settings.py::

TEXT_INLINE_EDITING = True

This will add a toggle button to the toolbar to allow to switch inline editing on and off for the current session.

When inline editing is active the editor will save the plugin's content each time it loses focus. If only text has changed the user can immediately continue to edit. If a text-enabled plugin was changed, added, or removed he page will refresh to update the page tree and get the correctly rendered version of the changed plugin.

Default content in Placeholder

---

If you use Django-CMS >= 3.0, you can use TextPlugin in "default_plugins" (see docs about the CMS_PLACEHOLDER_CONF_ setting in Django CMS 3.0). TextPlugin requires just one value: body where you write your default HTML content. If you want to add some "default children" to your automagically added plugin (i.e. a LinkPlugin), you have to put children references in the body. References are "%(_tag_child_<order>)s" with the inserted order of children. For example::

CMS_PLACEHOLDER_CONF = {
    'content': {
        'name' : _('Content'),
        'plugins': ['TextPlugin', 'LinkPlugin'],
        'default_plugins':[
            {
                'plugin_type':'TextPlugin',
                'values':{
                    'body':'<p>Great websites : %(_tag_child_1)s and %(_tag_child_2)s</p>'
                },
                'children':[
                    {
                        'plugin_type':'LinkPlugin',
                        'values':{
                            'name':'django',
                            'url':'https://www.djangoproject.com/'
                        },
                    },
                    {
                        'plugin_type':'LinkPlugin',
                        'values':{
                            'name':'django-cms',
                            'url':'https://www.django-cms.org'
                        },
                    },
                ]
            },

CKEDITOR_SETTINGS

---

You can override the setting CKEDITOR_SETTINGS in your settings.py::

CKEDITOR_SETTINGS = {
    'language': '{{ language }}',
    'toolbar': 'CMS',
    'skin': 'moono-lisa',
}

This is the default dict that holds all CKEditor settings.

Customizing plugin editor #########################

To customize the plugin editor, use toolbar_CMS attribute, as in::

CKEDITOR_SETTINGS = {
    'language': '{{ language }}',
    'toolbar_CMS': [
        ['Undo', 'Redo'],
        ['cmsplugins', '-', 'ShowBlocks'],
        ['Format', 'Styles'],
    ],
    'skin': 'moono-lisa',
}

Customizing HTMLField editor ############################

If you use HTMLField from djangocms_text_ckeditor.fields in your own models, use toolbar_HTMLField attribute::

CKEDITOR_SETTINGS = {
    'language': '{{ language }}',
    'toolbar_HTMLField': [
        ['Undo', 'Redo'],
        ['ShowBlocks'],
        ['Format', 'Styles'],
    ],
    'skin': 'moono-lisa',
}

You can further customize each HTMLField field by using different configuration parameter in your settings::

models.py

class Model1(models.Model):
    text = HTMLField(configuration='CKEDITOR_SETTINGS_MODEL1')

class Model2(models.Model):
    text = HTMLField(configuration='CKEDITOR_SETTINGS_MODEL2')

settings.py

CKEDITOR_SETTINGS_MODEL1 = {
    'toolbar_HTMLField': [
        ['Undo', 'Redo'],
        ['ShowBlocks'],
        ['Format', 'Styles'],
        ['Bold', 'Italic', 'Underline', '-', 'Subscript', 'Superscript', '-', 'RemoveFormat'],
    ]
}

CKEDITOR_SETTINGS_MODEL2 = {
    'toolbar_HTMLField': [
        ['Undo', 'Redo'],
        ['Bold', 'Italic', 'Underline', '-', 'Subscript', 'Superscript', '-', 'RemoveFormat'],
    ]
}

#. Add configuration='MYSETTING' to the HTMLField usage(s) you want to customize; #. Define a setting parameter named as the string used in the configuration argument of the HTMLField instance with the desired configuration;

Values not specified in your custom configuration will be taken from the global CKEDITOR_SETTINGS.

For an overview of all the available settings have a look here:

http://docs.ckeditor.com/#!/api/CKEDITOR.config

Inline preview

The child plugins of TextPlugin can be rendered directly inside CKEditor if text_editor_preview isn't False. However there are few important points to note:

• by default CKEditor doesn't load CSS of your project inside the editing area and has specific settings regarding empty tags, which could mean that things will not look as they should until CKEditor is configured correctly.

  See examples:

  • add styles and js configuration_
  • stop CKEditor from removing empty spans_ (useful for iconfonts)

• if you override widget default behaviour - be aware that it requires the property "allowedContent" to contain cms-plugin[*] as this custom tag is what allows the inline previews to be rendered

• Important note: please avoid html tags in __str__ representation of text enabled plugins - this messes up inline preview.

• If you're adding a Text Plugin as a child inside another plugin and want to style it conditionally based on the parent - you can add CMSPluginBase.child_ckeditor_body_css_class attribute to the parent class.

Drag & Drop Images

In IE and Firefox based browsers it is possible to drag and drop a picture into the text editor. This image is base64 encoded and lives in the 'src' attribute as a 'data' tag.

We detect this images, encode them and convert them to picture plugins. If you want to overwrite this behavior for your own picture plugin:

There is a setting called::

TEXT_SAVE_IMAGE_FUNCTION = 'djangocms_text_ckeditor.picture_save.create_picture_plugin'

you can overwrite this setting in your settings.py and point it to a function that handles image saves. Have a look at the function create_picture_plugin for details.

To completely disable the feature, set TEXT_SAVE_IMAGE_FUNCTION = None.

Usage as a model field

If you want to use the widget on your own model fields, you can! Just import the provided HTMLField like so::

from djangocms_text_ckeditor.fields import HTMLField

And use it in your models, just like a TextField::

class MyModel(models.Model):
    myfield = HTMLField(blank=True)

This field does not allow you to embed any other CMS plugins within the text editor. Plugins can only be embedded within Placeholder fields.

If you need to allow additional plugins to be embedded in a HTML field, convert the HTMLField to a Placeholderfield and configure the placeholder to only accept TextPlugin. For more information on using placeholders outside of the CMS see:

http://docs.django-cms.org/en/latest/how_to/placeholders.html

Auto Hyphenate Text

You can hyphenate the text entered into the editor, so that the HTML entity ­ (soft-hyphen_) automatically is added in between words, at the correct syllable boundary.

To activate this feature, pip install django-softhyphen. In settings.py add 'softhyphen' to the list of INSTALLED_APPS. django-softhyphen_ also installs hyphening dictionaries for 25 natural languages.

In case you already installed django-softhyphen but do not want to soft hyphenate, set TEXT_AUTO_HYPHENATE to False.

.. _soft-hyphen: http://www.w3.org/TR/html4/struct/text.html#h-9.3.3 .. _django-softhyphen: https://github.com/datadesk/django-softhyphen

Extending the plugin

.. NOTE:: Added in version 2.0.1

You can use this plugin as base to create your own CKEditor-based plugins.

You need to create your own plugin model extending AbstractText::

from djangocms_text_ckeditor.models import AbstractText

class MyTextModel(AbstractText):
    title = models.CharField(max_length=100)

and a plugin class extending TextPlugin class::

from djangocms_text_ckeditor.cms_plugins import TextPlugin
from .models import MyTextModel


class MyTextPlugin(TextPlugin):
    name = _(u"My text plugin")
    model = MyTextModel

plugin_pool.register_plugin(MyTextPlugin)

Note that if you override the render method that is inherited from the base TextPlugin class, any child text plugins will not render correctly. You must call the super render method in order for plugin_tags_to_user_html() to render out all child plugins located in the body field. For example::

from djangocms_text_ckeditor.cms_plugins import TextPlugin
from .models import MyTextModel


class MyTextPlugin(TextPlugin):
    name = _(u"My text plugin")
    model = MyTextModel

    def render(self, context, instance, placeholder):
        context.update({
            'name': instance.name,
        })
        # Other custom render code you may have
    return super().render(context, instance, placeholder)

plugin_pool.register_plugin(MyTextPlugin)

You can further customize your plugin_ as other plugins.

.. _customize your plugin: http://docs.django-cms.org/en/latest/how_to/custom_plugins.html

Adding plugins to the "CMS Plugins" dropdown

If you have created a plugin that you want to use within Text plugins you can make them appear in the dropdown by making them text_enabled. This means that you assign the property text_enabled of a plugin to True, the default value is False. Here is a very simple implementation::

class MyTextPlugin(TextPlugin):
    name = "My text plugin"
    model = MyTextModel
    text_enabled = True

When the plugin is picked up, it will be available in the CMS Plugins dropdown, which you can find in the editor. This makes it very easy for users to insert special content in a user-friendly Text block, which they are familiair with.

The plugin will even be previewed in the text editor. Pro-tip: make sure your plugin provides its own icon_alt method. That way, if you have many text_enabled-plugins, it can display a hint about it. For example, if you created a plugin which displays prices of configurable product, it can display a tooltip with the name of that product.

For more information about extending the CMS with plugins, read django-cms doc_ on how to do this.

.. _django-cms doc: http://docs.django-cms.org/en/latest/reference/plugins.html#cms.plugin_base.CMSPluginBase.text_enabled

Configurable sanitizer

djangocms-text-ckeditor uses html5lib_ to sanitize HTML to avoid security issues and to check for correct HTML code. Sanitisation may strip tags usesful for some use cases such as iframe; you may customize the tags and attributes allowed by overriding the TEXT_ADDITIONAL_TAGS and TEXT_ADDITIONAL_ATTRIBUTES settings::

TEXT_ADDITIONAL_TAGS = ('iframe',)
TEXT_ADDITIONAL_ATTRIBUTES = ('scrolling', 'allowfullscreen', 'frameborder')

In case you need more control on sanitisation you can extend AllowTokenParser class and define your logic into parse() method. For example, if you want to skip your donut attribute during sanitisation, you can create a class like this::

from djangocms_text_ckeditor.sanitizer import AllowTokenParser


class DonutAttributeParser(AllowTokenParser):

    def parse(self, attribute, val):
        return attribute.startswith('donut-')

And add your class to ALLOW_TOKEN_PARSERS settings::

ALLOW_TOKEN_PARSERS = (
    'mymodule.DonutAttributeParser',
)

NOTE: Some versions of CKEditor will pre-sanitize your text before passing it to the web server, rendering the above settings useless. To ensure this does not happen, you may need to add the following parameters to CKEDITOR_SETTINGS::

  ...
  'basicEntities': False,
  'entities': False,
  ...

To completely disable the feature, set TEXT_HTML_SANITIZE = False.

See the html5lib documentation_ for further information.

Search

djangocms-text-ckeditor works well with aldryn-search <https://github.com/aldryn/aldryn-search>_ to make text content using Haystack.

Development

pre-commit hooks

The repo uses pre-commit git hooks to run tools which ensure code quality.

To utilise this, run pip install pre-commit and then pre-commit install.

Building the JavaScript

djangocms-text-ckeditor distributes a javascript bundle required for the plugin to work, which contains CKEditor itself and all the necessary plugins for functioning within CMS. To build the bundle you need to have to install dependencies with npm install and then to run gulp bundle.

This command also updates the file name loaded based on the file contents.

Updating the CKEditor

Make sure to use the url in build config <https://github.com/divio/djangocms-text-ckeditor/blob/master/djangocms_text_ckeditor/static/djangocms_text_ckeditor/ckeditor/build-config.js#L16>_.

Running Tests

You can run tests by executing::

virtualenv env
source env/bin/activate
pip install -r tests/requirements.txt
python setup.py test
