A Django model field and widget that renders a customizable WYSIWYG/rich text editor

Project description

Latest Version https://travis-ci.org/jaap3/django-richtextfield.svg?branch=master https://coveralls.io/repos/jaap3/django-richtextfield/badge.svg?branch=master

A Django model field and widget that renders a customizable rich text/WYSIWYG widget.

Supports global editor settings, reusable editor profiles and per field & widget settings. There’s built-in support for pluggable server side content sanitizers.

Tested with TinyMCE and CKEditor. Designed to be easily extended to use other editors.

Quickstart

Install django-richtextfield and add it to your Django project’s INSTALLED_APPS, django.contrib.admin must also be in INSTALLED_APPS:

INSTALLED_APPS = [
    'django.contrib.admin',
    ...
    'djrichtextfield'
]

Add the urls to the project’s urlpatterns:

path('djrichtextfield/', include('djrichtextfield.urls'))

Configure django-richtextfield in settings.py:

DJRICHTEXTFIELD_CONFIG = {
    'js': ['//tinymce.cachefly.net/4.1/tinymce.min.js'],
    'init_template': 'djrichtextfield/init/tinymce.js',
    'settings': {
        'menubar': False,
        'plugins': 'link image',
        'toolbar': 'bold italic | link image | removeformat',
        'width': 700
    }
}

Now you’re ready to use the field in your models:

from djrichtextfield.models import RichTextField

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

or forms:

from djrichtextfield.widgets import RichTextWidget

class CommentForm(forms.ModelForm):
    content = forms.CharField(widget=RichTextWidget())

Configuration

Define the DJRICHTEXTFIELD_CONFIG dictionary in your project settings. This dictionary can have the following keys:

Javascript souce(s)

'js'

A list of required javascript files. These can be URLs to a CDN or paths relative to your STATIC_URL e.g.:

'js': ['//cdn.ckeditor.com/4.4.4/standard/ckeditor.js']

or:

'js': ['path/to/editor.js', 'path/to/plugin.js']

CSS souce(s)

'css'

A dictionary of CSS files required for various forms of output media. These can be URLs to a CDN or paths relative to your STATIC_URL e.g.:

'css': {
    'all': [
        'https://stackpath.bootstrapcdn.com/bootstrap/4.1.3/css/bootstrap.min.css'
    ]
}

or:

'css': {'all': ['path/to/editor.css', 'path/to/plugin.css']}

Editor init template

'init_template'

Path to the init template for your editor. Currently django-richtextfield ships with two templates, either:

'init_template': 'djrichtextfield/init/tinymce.js'

or:

'init_template': 'djrichtextfield/init/ckeditor.js'

Editor settings

'settings'

A Python dictionary with the default configuration data for your editor e.g.:

'settings': {  # TinyMCE
    'menubar': False,
    'plugins': 'link image',
    'toolbar': 'bold italic | link image | removeformat',
    'width': 700
}

or:

'settings': {  # CKEditor
    'toolbar': [
        {'items': ['Format', '-', 'Bold', 'Italic', '-',
                   'RemoveFormat']},
        {'items': ['Link', 'Unlink', 'Image', 'Table']},
        {'items': ['Source']}
    ],
    'format_tags': 'p;h1;h2;h3',
    'width': 700
}

Editor profiles

'profiles'

This is an optional configuration key. Profiles are “named” custom settings used to configure specific type of fields. You can configure profiles like this:

'profiles': {
    'basic': {
        'toolbar': 'bold italic | removeformat'
    },
    'advanced': {
        'plugins': 'link image table code',
        'toolbar': 'formatselect | bold italic | removeformat |'
                   ' link unlink image table | code'
    }
}

Note

A profile is treated the same way as directly defined field & widget settings. This means that profile settings are merged with the defaults!

Content sanitizers

'sanitizer'

This is an optional configuration key. A sanitizer can be used to process submitted values before it is returned by the widget. By default no processing is performed on submitted values. You can configure a sanitizer either by providing a function or an importable path to a function, like so:

'sanitizer': lambda value: '<h1>Title</h1>' + value

or:

'sanitizer': 'bleach.clean'
'sanitizer_profiles'

This is an optional configuration key. It is possible to override the default or configured sanitizer for each of the configured profiles. For example to set a custom sanitizer for the advanced profile:

'sanitizer_profiles': {
    'advanced': lambda value: value + 'This text has been sanitized.'
}

Field & Widget settings

You can override the default settings per field:

class CommentForm(forms.ModelForm):
    content = forms.CharField(widget=RichTextWidget())
    content.widget.field_settings = {'your': 'custom', 'settings': True}

or:

class Post(models.Model):
    content = RichTextField(
        field_settings={'your': 'custom', 'settings': True},
        sanitizer='bleach.linkify'
    )

It’s recommended to use profiles, they make it easier to switch configs or even editors on a later date. You use a profile like this:

class CommentForm(forms.ModelForm):
    content = forms.CharField(widget=RichTextWidget(field_settings='basic'))

or:

class Post(models.Model):
    content = RichTextField(field_settings='advanced')

Note

Fields always inherit the default settings, customs settings and profiles are merged with the defaults!

Custom init / Using another editor

It should be fairly easy to use this project with another editor. All that’s required is to configure DJRICHTEXTFIELD_CONFIG to load the right Javascript/CSS files and to create a custom init template.

For example, to use jQuery based Summernote (lite) editor:

DJRICHTEXTFIELD_CONFIG = {
    'js': [
        '//cdnjs.cloudflare.com/ajax/libs/jquery/3.2.1/jquery.js',
        '//cdnjs.cloudflare.com/ajax/libs/summernote/0.8.9/summernote-lite.js',
    ],
    'css': {
        'all': [
            '//cdnjs.cloudflare.com/ajax/libs/summernote/0.8.9/summernote-lite.css',
        ]
    },
    'init_template': 'path/to/init/summernote.js',
    'settings': {
        'followingToolbar': False,
        'minHeight': 250,
        'width': 700,
        'toolbar': [
            ['style', ['bold', 'italic', 'clear']],
        ],
    }
}

Init template

The init template is a Django template (so it should be in the template and not in the static directory). It contains a tiny bit of Javascript that’s called to initialize each editor. For example, the init template for Summernote would like this:

$('#' + id).summernote(settings)

The init template has the following Javascript variables available from the outer scope:

$e
jQuery wrapped textarea to be replaced (using the jQuery version bundled with Django’s admin)
id
The id attribute of the textarea
default_settings
DJRICHTEXTFIELD_CONFIG['settings'] as a JS object
custom_settings
The field_settings as a JS object
settings
Merge of default_settings and custom_settings

Handling uploads & other advanced features

django-richtextfield built to be editor agnostic. This means that it’s up to you to handle file uploads, show content previews and support other “advanced” features.
