Using rich text editor

You can customize the templates and add custom javascript code to enable CKEditor to your fields. In order to use CKEditor you need to inject some JS code into the SQLAdmin and that works by customizing the templates.

Let's say you have the following model:

class Post(Base):
    id = Column(Integer, primary_key=True)
    content = Column(Text, nullable=False)

• First create a templates/sqladmin directory in your project.

• Then add a file custom_edit.html there with the following content:

  custom_edit.html

  {% extends "sqladmin/edit.html" %}
  {% block tail %}
  <script src="https://cdn.ckeditor.com/ckeditor5/39.0.1/classic/ckeditor.js"></script>
  <script>
      ClassicEditor
          .create(document.querySelector('#content'))
          .catch(error => {
              console.error(error);
          });
  </script>
  {% endblock %}
  

• Use the custom_edit.html template in your admin:

class PostAdmin(ModelView, model=Post):
    edit_template = "custom_edit.html"

Now whenever editing a Post object in admin, the CKEditor will be applied to the content field of the model. You can do the same thing with create_template field.
