3. Include the app URLconf in your project/urls.py like this:

from django.conf import settings
from django.conf.urls.static import static

# [ ... ]

urlpatterns += [
    path("ckeditor5/", include('django_ckeditor_5.urls'), name="ck_editor_5_upload_file"),
] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

4. Add to your project/models.py:

from django.db import models
from django_ckeditor_5.fields import CKEditor5Field


class Article(models.Model):
    title=models.CharField('Title', max_length=200)
    text=CKEditor5Field('Text', config_name='extends')

Includes the following ckeditor5 plugins:

Examples

Example of using a widget in a form:

from django import forms

from django_ckeditor_5.widgets import CKEditor5Widget
from .models import Comment


class CommentForm(forms.ModelForm):
      """Form for comments to the article."""

      def __init__(self, *args, **kwargs):
          super().__init__(*args, **kwargs)
          self.fields["text"].required = False

      class Meta:
          model = Comment
          fields = ("author", "text")
          widgets = {
              "text": CKEditor5Widget(
                  attrs={"class": "django_ckeditor_5"}, config_name="comment"
              )
          }

Custom storage example:

import os
from urllib.parse import urljoin

from django.conf import settings
from django.core.files.storage import FileSystemStorage


class CustomStorage(FileSystemStorage):
    """Custom storage for django_ckeditor_5 images."""

    location = os.path.join(settings.MEDIA_ROOT, "django_ckeditor_5")
    base_url = urljoin(settings.MEDIA_URL, "django_ckeditor_5/")

Rename the uploaded images using uuid:

You can rename the images using uuid value and maintaning the extension in lower case. Example if your uploaded image original name was my-image.JPG now would be acb34ded-f203-431a-9005-387cc24a892e.jpg

You need to specity the settings variable with True value

CKEDITOR_5_UPLOAD_IMAGES_RENAME_UUID = True

Custom upload_url example:

You can use a custom upload_url to satisfy your business logic needs.

If you want to use a custom upload_url, You need to create a custom view class that extends UploadImageView

import os
import uuid
from django_ckeditor_5.views import UploadImageView


class CustomUploadImageView(UploadImageView):
    """Custom View to upload images for django_ckeditor_5 images."""
    def handle_uploaded_file(self, f):
        fs = self.get_storage_class()()
        filename = f.name.lower()
        # Here you can apply custom actions before the file is saved. For example optimize the image size
        if getattr(settings, "CKEDITOR_5_UPLOAD_IMAGES_RENAME_UUID", None) is True:
            new_file_name = f"{uuid.uuid4()}{os.path.splitext(filename)[1]}"
            filename = fs.save(new_file_name, f)
        # Here you can apply custom actions after the file is saved
        return fs.url(filename)

You need to add the custom url to your app urls.py file

from . import views # or from .views import CustomUploadImageView
path("custom_image_upload/", views.CustomUploadImageView.as_view(),name="ck_editor_5_upload_image",),

Finally You need to specify in the settings the CKEDITOR_5_UPLOAD_IMAGE_URL_NAME variable with the name of your custom_image_upload url view

CKEDITOR_5_UPLOAD_IMAGE_URL_NAME = "your_app_name:ck_editor_5_upload_image"

Changing the language:

You can change the language via the language key in the config

CKEDITOR_5_CONFIGS = {
  'default': {
      'toolbar': ['heading', '|', 'bold', 'italic', 'link',
                  'bulletedList', 'numberedList', 'blockQuote', 'imageUpload', ],
      'language': 'de',
  },

language can be either:

1. a string containing a single language
2. a list of languages
3. a dict {"ui": <a string (1) or a list of languages (2)>}

If you want the language to change with the user language in django you can add CKEDITOR_5_USER_LANGUAGE=True to your django settings. Additionally you will have to list all available languages in the ckeditor config as shown above.

Installing from GitHub:

cd your_root_project
git clone https://github.com/hvlads/django-ckeditor-5.git

Example Sharing content styles between front-end and back-end:

To apply ckeditor5 styling outside of the editor, download content.styles.css from the official ckeditor5 docs and include it as a styleshet within your HTML template. You will need to add the ck-content class to the container of your content for the styles to be applied. https://ckeditor.com/docs/ckeditor5/latest/installation/advanced/content-styles.html#sharing-content-styles-between-frontend-and-backend

<link rel="stylesheet" href="path/to/assets/content-styles.css" type="text/css">
...
<div class="ck-content">
<p>ckeditor content</p>
</div>
