Cannot import name error in Django split models

Question

I have split the Django models into multiple model files following the follow file tree structure,

+-api(app)-+
           +-__init__.py
           +-models -+
                     |
                     +-__init__.py
                     +-model1.py
                     +-model2.py
                     +-model3.py
           +-serializers-+
                     |
                     +-__init__.py
                     +- model1_serializer.py
           +-views
           +-apps.py
               ...

my __init__.py in models looks like,

from .model1 import *
from .model2 import *

and serializer __init__.py files look like this,

from .model1_serializer import MBTITypeSerializer

I have splitter views files and serializer files. When I try to import models some of them imports without any problem, but some imports not working. I have observed if I change the import order in __init__.py file the working imports change. This is how I tried to import models,

in serializers

from api.models import MBTIType
...

Here is the error trace,

    from api.models import Model1
ImportError: cannot import name 'Model1' from 'api.models' (D:\\implementation\backend\api\models\__init__.py)

Hoping any guidance to solve the issue.

Answer 1

check your model2.py, you have there on line 5 from api.serializers import serilizer1

But you don't need to have serializer1 in models.
