forms.py:

from ckeditor_uploader.widgets import ckeditoruploadingwidget   class paymentform(forms.form):     comments = forms.charfield(widget=ckeditoruploadingwidget()) 

to integrate ckeditor js scripts i'm using {{ form.media }} in template.

first of tried search info errors , know fixes, of founded doesn't worked me. found similar questions ckeditor here, without working solution.

when checked js scripts, found problem in javascript of google material design lite css framework https://github.com/google/material-design-lite

when material.min.js integrated page scripts - ckeditor not work. not minified framework js: https://code.getmdl.io/1.3.0/material.js

ps: first question ever made here, sorry inconvenience.
