LookupError when using HTMLField in a custom user model

[danielsamuels]

I've got a custom user model in my project, but it appears to be the case that if I attempt to use a HTMLField within it (for example, if I want a 'biography' field), it causes a LookupError because utils.py imports cms.models.CMSPlugin which eventually tries to get the custom user model which doesn't exist yet.

Here's a simple model which should reproduce the error:

from django.contrib.auth.models import AbstractBaseUser, PermissionsMixin
from djangocms_text_ckeditor.fields import HTMLField


class Individual(AbstractBaseUser, PermissionsMixin):

    biography = HTMLField(
        'professional biography',
        blank=True,
        null=True,
    )

and here's the relevant part of the traceback:

  File "redacted/apps/individuals/models.py", line 4, in <module>
    from djangocms_text_ckeditor.fields import HTMLField
  File ".venv/lib/python3.6/site-packages/djangocms_text_ckeditor/fields.py", line 7, in <module>
    from .html import clean_html
  File ".venv/lib/python3.6/site-packages/djangocms_text_ckeditor/html.py", line 14, in <module>
    from .utils import plugin_to_tag
  File ".venv/lib/python3.6/site-packages/djangocms_text_ckeditor/utils.py", line 8, in <module>
    from cms.models import CMSPlugin
  File ".venv/lib/python3.6/site-packages/cms/models/__init__.py", line 4, in <module>
    from .permissionmodels import *  # nopyflakes
  File ".venv/lib/python3.6/site-packages/cms/models/permissionmodels.py", line 21, in <module>
    User = apps.get_registered_model(user_app_name, user_model_name)
  File ".venv/lib/python3.6/site-packages/django/apps/registry.py", line 268, in get_registered_model
    "Model '%s.%s' not registered." % (app_label, model_name))
LookupError: Model 'individuals.Individual' not registered.

The order of apps in my INSTALLED_APPS is:

[
    'redacted.apps.individuals',
    'cms',
    'djangocms_text_ckeditor',
]

Currently experiencing the same error. My current workaround is to import HTMLField in the object that requires it :/

djangocms-text-ckeditor is importing CMSPlugin from django-cms at module level, which has the requirement that the user model be already registered. I believe this should be imported at function level, like they do in django-cms: https://github.com/divio/django-cms/blob/50dee524a1789d2259d760ba6726072907bad36b/cms/utils/moderator.py#L25
