How to import models from one app to another app in Django?

I am trying to reference a model (Person) from one app, in the views-file of another app. Unfortunately, I get an "unresolved reference"-error. Is it possible to reference models from other apps in Django? If so, what am I doing wrong?

Let me demonstrate with an example:

The image below shows my project. I am currently in the views.py (marked in green), in the app called "autocomplete". I want to reference a person-model in the file "models.py" (marked in red), that belongs to the app "resultregistration". However, I get the error "Unresolved reference Person", even though the class Person does exist in models.py

enter image description here

The file settings.py is in the athlitikos/athlitikos - folder, and manage.py is in only athlitikos (as seen in the image below)

enter image description here

Any help would be strongly appreciated!

Edit: I now tried running "from ..resultregistration.models import Person", because I saw that what I did in the screenshot was obviously wrong. However, then I get the error message " attempted relative import beyond top-level package"

Thank you for your time!

resultregistration.models should do it. Just make sure the app is added to the installed apps in your settings.py.

When doing the import from pycharm, it starts looking from the level of your present file, which is autocomplete/views.py, but Django starts from the project level, which is the level of your manage.py, so you can use from resultregistration.models import Person directly. Even though pycharm's inspections will show you errors in the code, it will pass when you running the project.

I think it will work:

from athlitikos.resultregistration.models import Person

If we analyse your directory tree, we can see that:

athlitikos
    autocomplete
        views.py
    resultregistration
        models.py

In the views.py in autocomplete you can reference to other modules with relative path. Try this:

from ..resultregistration.models import Person

The first dot goes up to autocomplete, the second dot goes up to athlitikos. Now from there you can access resultregistration and everything underneath.

mm why you repeat athlitikos?, try replacing:

from athlitikos.athlitikos.resultregistration.models import Person

with

from resultregistration.models import Person

If the resultregistration app is in the project directory (the one containing manage.py) then you shouldn't include the project name athlitikos in the import at all. Try the following:

from resultregistration.models import Person
