export assistant models

[MartingaleCoda]

Fixes issue where python manage.py makemigrations expects PromptLog model to be deleted, as the explorer app doesn't include it in its models.py file.

Example of the issue when moving from 4.0.2 to 4.2.0:

python3 manage.py makemigrations --check
Migrations for 'explorer':
  /opt/venv/lib/python3.9/site-packages/explorer/migrations/0016_delete_promptlog.py
    - Delete model PromptLog

Issue 615 may be related.

Ahh, that makes sense. Thanks so much for clarifying. Yeah I'll bet that is source of the issue in #615. I'll have to figure out why I didn't catch it in testing...

Will get this into a point release.

Sounds good.

I don't think you need the explorer/assistant/__init__.py change I put in this pull request since you don't keep models as a folder instead of a file. I think the only important part is that the models for the explorer app include the models in the assistant module.

Have a good weekend! =)

Merged. Thanks again!
