Installation

Required

1. Install or add django-ckeditor to your python path.

2. Add ckeditor to your INSTALLED_APPS setting.

3. Add a CKEDITOR_UPLOAD_PATH setting to the project's settings.py file. This setting specifies the folder to your CKEditor media upload directory in Amazon S3.

   CKEDITOR_UPLOAD_PATH = "uploads"

#. Add a AWS_DEFAULT_ACL setting to the project's settings.py file. This setting specifies the permissions(ACL) of the image access by the Amazon S3. The values of the ACL is private, public-read, public-read-write, authenticated-read.

AWS_DEFAULT_ACL = 'public-read'

1. Run the collectstatic management command: $ /manage.py collectstatic. This'll copy static CKEditor require media resources into the directory given by the STATIC_ROOT setting. See Django's documentation on managing static files for more info.

2. Add CKEditor URL include to your project's urls.py file:

   (r'^ckeditor/', include('ckeditor.urls')),
   

3. Install boto the library amazon s3 <https://github.com/boto/boto>

Optional

1. Set the CKEDITOR_RESTRICT_BY_USER setting to True in the project's settings.py file (default False). This restricts access to uploaded images to the uploading user (e.g. each user only sees and uploads their own images). Superusers can still see all images. NOTE: This restriction is only enforced within the CKEditor media browser.

2. Add a CKEDITOR_UPLOAD_PREFIX setting to the project's settings.py file. This setting specifies a URL prefix to media uploaded through CKEditor, i.e.:

   CKEDITOR_UPLOAD_PREFIX = "http://media.lawrence.com/media/ckuploads/
   

   (If CKEDITOR_UPLOAD_PREFIX is not provided, the media URL will fall back to MEDIA_URL with the difference of MEDIA_ROOT and the uploaded resource's full path and filename appended.)

3. Add a CKEDITOR_CONFIGS setting to the project's settings.py file. This specifies sets of CKEditor settings that are passed to CKEditor (see CKEditor's Setting Configurations), i.e.:

   CKEDITOR_CONFIGS = {
       'awesome_ckeditor': {
           'toolbar': 'Basic',
       },
   }
   

   The name of the settings can be referenced when instantiating a RichTextField:

   content = RichTextField(config_name='awesome_ckeditor')
   

   The name of the settings can be referenced when instantiating a CKEditorWidget:

   widget = CKEditorWidget(config_name='awesome_ckeditor')
   

   By specifying a set named default you'll be applying its settings to all RichTextField and CKEditorWidget objects for which config_name has not been explicitly defined

   CKEDITOR_CONFIGS = {
       'default': {
           'toolbar': 'Full',
           'height': 300,
           'width': 300,
       },
   }
   

Usage

Field

The quickest way to add rich text editing capabilities to your models is to use the included RichTextField model field type. A CKEditor widget is rendered as the form field but in all other regards the field behaves as the standard Django TextField. For example:

from django.db import models
from ckeditor.fields import RichTextField

class Post(models.Model):
    content = RichTextField()

Widget

Alernatively you can use the included CKEditorWidget as the widget for a formfield. For example:

from django import forms
from django.contrib import admin
from ckeditor.widgets import CKEditorWidget

from post.models import Post

class PostAdminForm(forms.ModelForm):
    content = forms.CharField(widget=CKEditorWidget())
    class Meta:
        model = Post

class PostAdmin(admin.ModelAdmin):
    form = PostAdminForm

admin.site.register(Post, PostAdmin)

Amazon S3

Add the following sentences in the setting to the project's settings.py file.

Add to TEMPLATE_CONTEXT_PROCESSORS in settings.py:

'django.core.context_processors.request'

If you want S3 storage as your default file back-end:

# If you don't want this to be the global default, just make sure you
# specify the S3BotoStorage_AllPublic backend on a per-field basis.
DEFAULT_FILE_STORAGE = 'ckeditor.backends.s3boto.S3BotoStorage_AllPublic'

Then setup some values used by the backend:

AWS_ACCESS_KEY_ID = 'YourS3AccessKeyHere'
AWS_SECRET_ACCESS_KEY = 'YourS3SecretAccessKeyHere'
AWS_STORAGE_BUCKET_NAME = 'OneOfYourBuckets'

If you would like to use a vanity domain instead of s3.amazonaws.com, you first should configure it in amazon and then add this to settings:

AWS_STORAGE_BUCKET_CNAME = 'static.yourdomain.com'

If you want a cache buster for your thumbnails (a string added to the end of the image URL that causes browsers to re-fetch the image after changes), you can set a value like this:

MEDIA_CACHE_BUSTER = 'SomeValue'

You do not need to specify a cache buster.

If you aren't using the default S3 region, you can define it with the following setting:

AWS_REGION = 'us-east-1'

Managment Commands

Included is a management command to create thumbnails for images already contained in CKEDITOR_UPLOAD_PATH. This is useful to create thumbnails when starting to use django-ckeditor with existing images. Issue the command as follows:

$ ./manage.py generateckeditorthumbnails

NOTE: If you're using custom views remember to include ckeditor.js in your form's media either through {{ form.media }} or through a <script> tag. Admin will do this for you automatically. See Django's Form Media docs for more info.
