Re: how to split in multiple file class models.py?

Sorry for reviving an old topic, but I have a models.py file that is >15,000 lines and would like to chop it up (PyCharm is groaning under the weight!).

How would I handle the imports between the chopped-up files in a models module where the referenced foreign key model is in a different file?

Is there a risk of circular imports?

Thanks,

Richard Brockie

So,

Boney M's assumption here is correct.

You just need to import all of your models in the __init__.py file using relative imports, so for example:

from .car import Car

and so on.

This works perfectly and I usually try to split the models in that way as not to get a models.py that is over 10000 lines long.

Just a thought, I haven't tested this: you might be able to trick access to subdirectories by importing those models in the top-level models/__init__.py - now that I think about it, you might have to do that with all the models... so your __init__ file would say something like:

```

from .car import SomeModel

from .otherPackage.other_model import SomeOtherModel

# and so on ...

```

Again, I could be way off here. I've never looked at the magic that parses the models on migration creation.

Best,

Benny

Hello everyone, I have a question about Django and the use of namespaces or packages to split the models.py file.
I would like to adopt the Java philosophy in which one file corresponds one class and one db table.
I tried to follow this guide, but it doesn't work.
https://docs.djangoproject.com/en/3.1/ref/applications/#namespace-packages-as-apps

when I execute this command: "python manage.py makemigrations myapp"

Return this warning: "No changes detected in app"

Is it possible to do this structure?

/models
    __init__py # if i use package, or without for namespace
         #common import
    car.py # class car
    group.py # class group
    manufactor.py # class manufactor
    /otherPackage
        __init__py
            common import
        otherClass.py

I hope you understand what I'd like to do.
Thank you.
