Flask-Admin and CKEditor WYSIWYG textarea integration. Basically, all you have to do: 1. Create new wtforms widget which will emit 'ckeditor' class 2. Make new wtforms field which will use this widget 3. Create new jinja2 template, which includes ckeditor javascript 4. Tell flask-admin to use new field and new template
from flask import Flask
from flask.ext.sqlalchemy import SQLAlchemy
from flask.ext import admin, wtf
from flask.ext.admin.contrib import sqlamodel
app = Flask(__name__)
app.config['SECRET_KEY'] = '123456790'
app.config['SQLALCHEMY_DATABASE_URI'] = 'sqlite:///test.sqlite'
db = SQLAlchemy(app)
class CKTextAreaWidget(wtf.TextArea):
def __call__(self, field, **kwargs):
kwargs.setdefault('class_', 'ckeditor')
return super(CKTextAreaWidget, self).__call__(field, **kwargs)
class CKTextAreaField(wtf.TextAreaField):
widget = CKTextAreaWidget()
class Test(db.Model):
id = db.Column(db.Integer, primary_key=True)
text = db.Column(db.UnicodeText)
class TestAdmin(sqlamodel.ModelView):
form_overrides = dict(text=CKTextAreaField)
create_template = 'edit.html'
edit_template = 'edit.html'
if __name__ == '__main__':
admin = admin.Admin(app)
admin.add_view(TestAdmin(Test, db.session))
db.create_all()
app.debug = True
app.run('0.0.0.0', 8000)
{% extends 'admin/model/edit.html' %}
{% block tail %}
{{ super() }}
<script src="http://cdnjs.cloudflare.com/ajax/libs/ckeditor/4.0.1/ckeditor.js"></script>
{% endblock %}

Adding more precise steps as it may help a novice like me.

Added this in my model.py

from flask_admin.contrib import sqla
from src.knowledge.form import CKTextAreaField

class Test(db.Model):
id = db.Column(db.Integer, primary_key=True)
text = db.Column(db.UnicodeText)

class TestAdmin(sqla.ModelView):
form_overrides = dict(text=CKTextAreaField)

create_template = 'edit.html'
edit_template = 'edit.html'

form.py

class CKTextAreaWidget(widgets.TextArea):
def call(self, field, *kwargs):
kwargs.setdefault('class
', 'ckeditor')
return super(CKTextAreaWidget, self).call(field,
*_kwargs)

class CKTextAreaField(TextAreaField):
widget = CKTextAreaWidget()

Also used this class in my form.py as follows:

class Question(Form):
question = CKTextAreaField('Question text')

Created edit.html with this text.

{% extends 'admin/model/edit.html' %}

{% block tail %}
{{ super() }}

<script src="http://cdnjs.cloudflare.com/ajax/libs/ckeditor/4.0.1/ckeditor.js"></script>

{% endblock %}

Don't worry from where it inherits.

Added following to manage.py

from flask.ext.admin import Admin

admin = Admin(app)
admin.add_view(TestAdmin(Test, db.session))
db.create_all()

I managed to get ckeditor in embededdocuments but it will not work until I save document and is there any way to reload ckeditor after adding new field before saving ?
