django-adminfiles
A file upload manager and picker for the Django admin, with support
for browsing and embedding from Flickr, Youtube, Vimeo, etc.
Upload files and view uploaded files (with thumbnails) in a
file-picker underneath any content textarea. Click on a file to add a
reference to it into the content area.
Inline file references can be customized per-mime-type to automate the
correct presentation of each file: tags (with additional markup
as needed) for images, links for downloadable files, even embedded
players for audio or video files. See the screencast

Usage
To use django-adminfiles in your Django project:
1. Add ``'adminfiles'`` to your ``INSTALLED_APPS`` setting. Also
add ``'sorl.thumbnail'`` if you have not installed it already.
2. Run ``python manage.py syncdb`` to to create the adminfiles database
tables.
3. Make the contents of the ``adminfiles/static/adminfiles`` directory
available at ``STATIC_URL/adminfiles``. This can be done by through
your webserver configuration, via an app such as
``django.contrib.staticfiles``, or by copying the files or making a
symlink.
4. Add ``url(r'^adminfiles/', include('adminfiles.urls'))`` in your
root URLconf.
5. Inherit content model admin options from
`FilePickerAdmin`_.
In addition, you may want to set the THUMBNAIL_EXTENSION
setting for
sorl-thumbnail
_ to "png"
rather than the default "jpg"
, so that
images with alpha transparency aren't broken when thumbnailed in the
adminfiles file-picker.
FilePickerAdmin
For each model you'd like to use the django-adminfiles
picker
with, inherit that model's admin options class from
adminfiles.admin.FilePickerAdmin
instead of the usual
django.contrib.admin.ModelAdmin
, and set the adminfiles_fields
attribute to a list/tuple of the names of the content fields it is
used with.
For instance, if you have a Post
model with a content
TextField, and you'd like to insert references into that TextField
from a django-adminfiles
picker::
from django.contrib import admin
from adminfiles.admin import FilePickerAdmin
from myapp.models import Post
class PostAdmin(FilePickerAdmin):
adminfiles_fields = ('content',)
admin.site.register(Post, PostAdmin)
The picker displays thumbnails of all uploaded images, and appropriate
icons for non-image files. It also allows you to filter and view only
images or only non-image files. In the lower left it contains links to
upload a new file or refresh the list of available files.
If you click on a file thumbnail/icon, a menu pops up with options to
edit or delete the uploaded file, or insert it into the associated
content field. To modify the default insertion options, set the
ADMINFILES_INSERT_LINKS
_ setting.
File references
When you use the file upload picker to insert an uploaded file
reference in a text content field, it inserts something like
<<<my-file-slug>>>
, built from the ADMINFILES_REF_START
_ and
ADMINFILES_REF_END
_ settings and the slug of the FileUpload
instance.
The reference can also contain arbitrary key=value option after the
file slug, separated by colons, e.g.:
<<<my-file-slug:class=left>>>
.
These generic references allow you to use django-adminfiles
with
raw HTML content or any type of text markup. They also allow you to
change uploaded files and have old references to the file pick up the
change (as long as the slug does not change). The URL path to the
file, or other metadata like the height or width of an image, are not
hardcoded in your content.
Rendering references
These references need to be rendered at some point into whatever
markup you ultimately want. The markup produced by the rendering is
controlled by the Django templates under adminfiles/render/
.
The template used is selected according to the mime type of the file
upload referenced. For instance, for rendering a file with mime type
image/jpeg
, the template used would be the first template of the
following that exists: adminfiles/render/image/jpeg.html
,
adminfiles/render/image/default.html
,
adminfiles/render/default.html
.
If a file should be rendered as if it had a different mime type
(e.g. an image you want to link to rather than display), pass the
as
option with the mime type you want it rendered as (where either
the sub-type or the entire mime-type can be replaced with
default
). For instance, with the default available templates if
you wanted to link to an image file, you could use
<<<my-image:as=default>>>
.
Two rendering templates are included with django-adminfiles
:
adminfiles/render/image/default.html
(used for any type of image)
and adminfiles/render/default.html
(used for any other type of
file). These default templates produce an HTML img
tag for images
and a simple a
link to other file types. They also respect three
key-value options: class
, which will be used as the the class
attribute of the img
or a
tag; alt
, which will be the
image alt text (images only; if not provided upload.title
is used
for alt text); and title
, which will override upload.title
as
the link text of the a
tag (non-images only).
You can easily override these templates with your own, and provide
additional templates for other file types. The template is rendered
with the following context:
upload
The FileUpload
model instance whose slug field matches the
reference. Useful attributes of this instance include
upload.upload
(a Django File object
_), upload.title
,
upload.description
, upload.mime_type
(first and second
parts separately accessible as upload.content_type
and
upload.sub_type
) and upload.is_image
(True if
upload.content_type
is "image"). Images also have
upload.height
and upload.width
available.
options
A dictionary of the key=value options in the reference.
If a reference is encountered with an invalid slug (no FileUpload
found in the database with that slug), the value of the
ADMINFILES_STRING_IF_NOT_FOUND
_ setting is rendered instead
(defaults to the empty string).
.. _Django File object: http://docs.djangoproject.com/en/dev/ref/files/file/
render_uploads template filter
django-adminfiles
provides two methods for making the actual
rendering happen. The simple method is a template filter:
render_uploads
. To use it, just load the adminfiles_tags
tag
library, and apply the render_uploads
filter to your content field::
{% load adminfiles_tags %}
{{ post.content|render_uploads }}
The render_uploads
filter just replaces any file upload references
in the content with the rendered template (described above).
The filter also accepts an optional argument: an alternate base path
to the templates to use for rendering each uploaded file
reference. This path will replace adminfiles/render
as the base
path in the mime-type-based search for specific templates. This allows
different renderings to be used in different circumstances::
{{ post.content|render_uploads:"adminfiles/alt_render" }}
For a file of mime type text/plain
this would use one of the
following templates: adminfiles/alt_render/text/plain.html
,
adminfiles/alt_render/text/default.html
, or
adminfiles/alt_render/default.html
.
render_upload template filter
If you have a FileUpload
model instance in your template and wish
to render just that instance using the normal rendering logic, you can
use the render_upload
filter. This filter accepts options in the
same "key=val:key2=val2" format used for passing options to
inline-embedded files; the special option template_path
specifies
an alternate base path for finding rendering templates::
{{ my_upload|render_upload:"template_path=adminfiles/alt_render:class=special" }}
pre-rendering at save time
In some cases, markup in content fields is pre-rendered when the model
is saved, and stored in the database or cache. In this case, it may be
preferable to also render the uploaded file references in that step,
rather than re-rendering them every time the content is displayed in
the template.
To use this approach, first you need to integrate the function
adminfiles.utils.render_uploads
into your existing content
pre-rendering process, which should be automatically triggered by
saving the content model.
The adminfiles.utils.render_uploads
function takes a content
string as its argument and returns the same string with all uploaded
file references replaced, same as the template tag. It also accepts a
template_path
argument, which is the same as the argument accepted
by the render_uploads template filter
_.
Integrating this function in the markup-rendering step is outside the
scope of django-adminfiles
. For instance, if using
django-markitup
_ with Markdown to process content markup, the
MARKITUP_FILTER
setting might look like this::
MARKITUP_FILTER = ("utils.markup_filter", {})
Which points to a function in utils.py
like this::
from markdown import markdown
from adminfiles.utils import render_uploads
def markup_filter(markup):
return markdown(render_uploads(markup))
Once this is done, set the ADMINFILES_USE_SIGNALS
_ setting to
True. Now django-adminfiles
will automatically track all
references to uploaded files in your content models. Anytime an
uploaded file is changed, all content models which reference it will
automatically be re-saved (and thus updated with the new uploaded
file).
.. _django-markitup: http://bitbucket.org/carljm/django-markitup
Embedding media from other sites
django-adminfiles
allows embedding media from any site that supports the
OEmbed protocol. OEmbed support is provided via djangoembed
_ or
django-oembed
_, one of which must be installed for embedding to work.
If a supported OEmbed application is installed, the render_uploads template filter
_ will also automatically replace any OEmbed-capable URLs with the
appropriate embed markup (so URLs from any site supported by the installed
OEmbed application can simply be pasted in to the content manually).
In addition, django-adminfiles
provides views in its filepicker to
browse Flickr photos, Youtube videos, and Vimeo videos and insert
their URLs into the context textarea with a click. To enable these
browsing views, set the ADMINFILES_YOUTUBE_USER
,
ADMINFILES_VIMEO_USER
, or ADMINFILES_FLICKR_USER
_ and
ADMINFILES_FLICKR_API_KEY
_ settings (and make sure the
dependencies
_ are satisfied).
To add support for browsing content from another site, just create a
class view that inherits from adminfiles.views.OEmbedView
and add
its dotted path to the ADMINFILES_BROWSER_VIEWS
_ setting. See the
existing views in adminfiles/views.py
for details.
To list the available browsing views and their status (enabled or
disabled, and why), django-adminfiles
provides an
adminfiles_browser_views
management command, which you can run
with ./manage.py adminfiles_browser_views
.
Settings
ADMINFILES_REF_START
Marker indicating the beginning of an uploaded-file reference in text
content. Defaults to '<<<'.
If you set this to something insufficiently distinctive (a string
that's likely to show up otherwise in your content), all bets are off.
Special regex characters are escaped, thus you can safely set it to
something like '[[[', but you can't do advanced regex magic with it.
ADMINFILES_REF_END
Marker indicating the end of an uploaded-file reference in text
content. Defaults to '>>>'.
If you set this to something insufficiently distinctive (a string
that's likely to show up otherwise in your content), all bets are off.
Special regex characters are escaped, thus you can safely set it to
something like ']]]', but you can't do advanced regex magic with it.
ADMINFILES_USE_SIGNALS
A boolean setting: should django-adminfiles
track which content
models reference which uploaded files, and re-save those content
models whenever a referenced uploaded file changes?
Set this to True if you already pre-render markup in content fields at
save time and want to render upload references at that same save-time
pre-rendering step.
Defaults to False. If this setting doesn't make sense to you, you can
safely just leave it False and use the render_uploads template filter
_.
ADMINFILES_STRING_IF_NOT_FOUND
The string used to replace invalid uploaded file references (given
slug not found). Defaults to u''
.
ADMINFILES_STDICON_SET
Django-adminfiles ships with a few icons for common file types, used
for displaying non-image files in the file-picker. To enable a broader
range of mime-type icons, set this setting to the name of an icon set
included at stdicon.com
_, and icons from that set will be linked.
.. _stdicon.com: http://www.stdicon.com
ADMINFILES_INSERT_LINKS
By default, the admin file picker popup menu for images allows
inserting a reference with no options, a reference with "class=left",
or a reference with "class=right". For non-images, the default popup
menu only allows inserting a reference without options. To change the
insertion options for various file types, set
ADMINFILES_INSERT_LINKS
to a dictionary mapping mime-types (or
partial mime-types) to a list of insertion menu options. For instance,
the default setting looks like this::
ADMINFILES_INSERT_LINKS = {
'': [('Insert Link', {})],
'image': [('Insert', {}),
('Insert (left)', {'class': 'left'}),
('Insert (right)', {'class': 'right'})]
}
Each key in the dictionary can be the first segment of a mime type
(e.g. "image"), or a full mime type (e.g. "audio/mpeg"), or an empty
string (the default used if no mime type matches). For any given file
the most specific matching entry is used. The dictionary should always
contain a default entry (empty string key), or some files may have no
insertion options.
Each value in the dictionary is a list of menu items. Each menu item
is a two-tuple, where the first entry is the user-visible name for the
insertion option, and the second entry is a dictionary of options to
be added to the inserted file reference.
ADMINFILES_UPLOAD_TO
The upload_to
argument that will be passed to the FileField
on
django-admin-upload
's FileUpload
model; determines where
django-adminfiles
keeps its uploaded files, relative to
MEDIA_URL
. Can include strftime formatting codes as described in the Django documentation
_. By default, set to 'adminfiles'
.
.. _in the Django documentation: http://docs.djangoproject.com/en/dev/ref/models/fields/#django.db.models.FileField.upload_to
ADMINFILES_THUMB_ORDER
The ordering that will be applied to thumbnails displayed in the
picker. Expects a tuple of field names, prefixed with -
to
indicate reverse ordering, same as "ordering" model Meta attribute
_. The default value is ('-upload_date')
; thumbnails
ordered by date uploaded, most recent first.
.. _"ordering" model Meta attribute: http://docs.djangoproject.com/en/dev/ref/models/options/#ordering
ADMINFILES_BROWSER_VIEWS
List of dotted paths to file-browsing views to make available in the
filepicker. The default setting includes all the views bundled with
django-adminfiles
::
['adminfiles.views.AllView',
'adminfiles.views.ImagesView',
'adminfiles.views.AudioView',
'adminfiles.views.FilesView',
'adminfiles.views.FlickrView',
'adminfiles.views.YouTubeView',
'adminfiles.views.VimeoView']
The last three may be disabled despite their inclusion in this setting
if their dependencies
_ are not satisfied or their required settings
are not set.
ADMINFILES_YOUTUBE_USER
Required for use of the Youtube video browser.
ADMINFILES_VIMEO_USER
Required for use of the Vimeo video browser.
ADMINFILES_VIMEO_PAGES
The Vimeo API returns 20 videos per page; this setting determines the
maximum number of pages to fetch (defaults to 1, Vimeo-imposed maximum of
3).
ADMINFILES_FLICKR_USER
Required for use of the Flickr photo browser.
ADMINFILES_FLICKR_API_KEY
Required for use of the Flickr photo browser.
JQUERY_URL
django-adminfiles
requires the jQuery Javascript library. By default,
django-adminfiles
uses the latest version of jQuery 1.4 hosted by Google,
via the URL http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js.
If you wish to use a different version of jQuery, or host it yourself, set the
JQUERY_URL
setting. JQUERY_URL
can be absolute or relative; if relative
it is relative to STATIC_URL
. For example::
JQUERY_URL = 'jquery.min.js'
This will use the jQuery available at STATIC_URL/jquery.min.js
.
