QUESTION
I am asking this question because I ran into this django.db.utils.IntegrityError: null value in column “lft” violates not-null constraint when I was using django-hordak which uses MPPT models.
Some of the solutions proposed are hacky
as they go against common practice but they work.
THE BASICS
In django when writing custom migrations for example when creating baseline data.

Answered 2019-Dec-02 at 16:33that is a very good question, as there is in deed a very big difference.
If you import a model, you will get whatever is currently defined in your model code. But what happens if you want to remove a model? How do you make sure your migration will still work?
That's why there is apps.get_model
. It will give you a "virtual" Model based on state defined by the previous migrations. Note that this is not the same as the Model in your code. It does not have any of the custom functions and behaviors you implemented unless they are part of the ORM API. In other words mostly fields and meta options like ordering and co.
Please also note that the correct signature is apps
not app_registry
. It should not be confused with the app registry in django.apps.apps
. It has a get_model
method too. This one however will return the model in your current code.
I know it can be all a bit confusing at first (and even later). I would suggest following a simple rule. Do not import any of your own code into a migration. Backport behavior into the migration, if you must.
I hope that distinction helps you a bit. Please leave me a comment if you have further questions. I am happy to extend my answer.

Install django-hordak
You can use django-hordak like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
