Wonderful rich text for Django

Project description

Django Prose

PyPI - Downloads PyPI - Python Version

Django Prose provides your Django applications with wonderful rich-text editing capabilities.

Requirements

  • Python 3.8 or later
  • Django 3.2 or later
  • Bleach 4.0 or later

Getting started

To get started with Django Prose, all you need to do is follow just four steps.

  1. Install django-prose

    We use and suggest using Poetry, although Pipenv and plain pip will work seamlessly as well

    poetry add django-prose
    
  2. Add to INSTALLED_APPS

    Add prose in your Django project's installed apps (example: example/example/settings.py):

    INSTALLED_APPS = [
        # Django stock apps (e.g. 'django.contrib.admin')
    
        'prose',
    
        # your application's apps
    ]
    
  3. Run migrations

    This is required so you can use Django Prose's built-in Document model:

    python manage.py migrate prose
    
  4. Include URLs

    You need to edit the main urls.py file of your Django project and include prose.urls:

    urlpatterns = [
        path('admin/', admin.site.urls),
        # other urls ...
        path("prose/", include("prose.urls")),
    ]
    

Now, you are ready to go 🚀.

Usage

There are different ways to use Django prose according to your needs. We will examine all of them here.

Rendering rich-text in templates

Rich text content essentially is HTML. For this reason it needs to be manually marked as safe, when rendered in Django templates. Example:

{{ document.content | safe}}

Small rich-text content

You might want to add rich-text content in a model that is just a few characters (e.g. 140), like an excerpt from an article. In that case we suggest using the RichTextField. Example:

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

class Article(models.Model):
    excerpt = RichTextField()

As mentioned above, you need to mark the article excerpt as safe, in order to render it:

<div class="article-excerpt">{{ article.excerpt | safe}}</div>

Large rich-text content

In case you want to store large rich-text content, like the body of an article, which can span to quite a few thousand characters, we suggest you use the AbstractDocument model. This will save large rich-text content in a separate database table, which is better for performance. Example:

from django.db import models
from prose.fields import RichTextField
from prose.models import AbstractDocument

class ArticleContent(AbstractDocument):
    pass

class Article(models.Model):
    excerpt = RichTextField()
    body = models.OneToOneField(ArticleContent, on_delete=models.CASCADE)

Similarly here as well, you need to mark the article's body as safe, in order to render it:

<div class="article-body">{{ article.body.content | safe}}</div>

Forms with rich-text editing

You can create forms for your Django Prose models, to provide rich-text editing functionality. In that case, you will also need to render form.media, to load Trix with its stylesheets.

<form  method="POST" >
  {% csrf_token %}
  
  {{ form.as_p }}
  {{ form.media }}
  
  <button type="submit">Submit</button>
</form>

The same is true also, if you are rendering the forms field manually.

Attachments

Django Prose can also handle uploading attachments with drag and drop. To set this up, first you need to:

  • Set up the MEDIA_ROOT and MEDIA_URL of your Django project (example in example/example/settings.py))

  • Include the Django Prose URLs (example in example/example/urls.py)

  • (Optional) Set up a different Django storage to store your files (e.g. S3)

  • Attachments are uploaded with a path structure of /YEAR/MONTH/DATE/UUID.EXT

  • By default, only files 5MB or less are allowed.

Allowed file size can be overridden by setting PROSE_ATTACHMENT_ALLOWED_FILE_SIZE in your Django project's settings file.

# File size in megabytes
PROSE_ATTACHMENT_ALLOWED_FILE_SIZE = 15

Full example

You can find a full example of a blog, built with Django Prose in the example directory.

🔒 A note on security

As you can see in the examples above, what Django Prose does is provide you with a user friendly editor (Trix) for your rich text content and then store it as HTML in your database. Since you will mark this HTML as safe in order to use it in your templates, it needs to be sanitised, before it gets stored in the database.

For this reason Django Prose is using Bleach to only allow the following tags and attributes:

  • Allowed tags: p, ul, ol, li, strong, em, div, span, a, blockquote, pre, figure, figcaption, br, code, h1, h2, h3, h4, h5, h6, picture, source, img
  • Allowed attributes: alt, class, id, src, srcset, href, media
