9,031 PointsGetting ImportError: cannot import name when trying to separate models to different files. Help!
I tried to separate the contents of the models.py to separate files.
Originally we had models.py(database, User and Post). Now, I have the following:
.
+-- app.py
+-- forms.py
+-- templates
+-- static
+-- models
| +-- user.py
| +-- post.py
+-- common
| +-- database.py
As a result of the separation, the two classes User which are in models.user.py and Post in models.post.py are now importing each other. (sort of cyclic dependency)
Moreover, I could not make the app work anymore now that the "stream" feature is now implemented. Traceback (most recent call last):
File "app.py", line 5, in <module>
import forms
File "C:\social_network_app\forms.py", line 6, in <module>
from models.user import User
File "C:\social_network_app\models\user.py", line 8, in <module>
from models.post import Post
File "C:\social_network_app\models\post.py", line 4, in <module>
from models.user import User
ImportError: cannot import name 'User'
How to resolve this?
Thanks in advance.

Treehouse Moderator 68,457 PointsDo you have an
__init__.py
file in both the common and models directories? The file can be empty.
