I just got an error when I try to log in. the error happens only when I add the save method in the User model. But when I remove the save method there is no error at all.

Using TinyMCE with filebrowser and grappelli
I've been wanting to set up a blog app with a WYSIWYG editor. I use S3 as the storage backend for image uploads outside of the editor. For that purpose, I use "django-storages". I have deployed this on Heroku and for that purpose, I use django-heroku as well. To enable image upload for TinyMCE i went ahead and installed Grappelli and filebrowser. I added the URLs for the same added the context processor for Grappelli, set the TINYMCE_FILEBROWSER setting to true. I ensured the URLs for filebrowser and grappelli come before the URL for admin When I call collectstatic, I get this messages like this Found another file with the destination path 'admin/js/timeparse.js'. It will be ignored since only the first encountered file is collected. If this is not what you want, make sure every static file has a unique path. When I open up admin and go to the image upload button on the editor, it doesn't show the upload icon. I was wondering if anyone who has had any experience with this can help me out? I am open to setting up some time with them as well :) Here's the rundown on settings.py INSTALLED_APPS = [ 'django.contrib.admin', … -
