ModuleNotFoundError w/ PlaceholderField #97

Closed b14s closed 5 years ago

b14s commented 5 years ago

I created a simple "Post" model with a few standard Django model fields and a django-fluent-content model PlaceholderField. It registers in the admin view, but when I attempt to instantiate the model I get "ModuleNotFoundError at /admin/content/post/add .... No module named 'django.contrib.admin.content_plugins'" and this traceback: `Environment:

It looks the path detection from https://github.com/django-fluent/django-fluent-utils/blob/master/fluent_utils/load.py#L86 failed on your OS.

I've released django-fluent-utils==2.0.1 which should fix this issue. I also noticed that you use Django 2.1 already. Not all apps are already fully tested on this new release. You may want to use Django<2.1 for now.
