I have two apps named collection, accounts. Both apps have models defined. I am importing a model ReporterProfile from accounts app to collection. Similarly, a model Report from the app collection to accounts.
The Report model from collection app is called in a model class method in accounts app like this:
from collection.models import Report
class ReporterProfile(models.Model):
....
def published_articles_number(self):
num = Report.objects.filter(reporterprofile=self.id).count()
return num
Similarly, I am importing ReporterProfile and User models from accounts app to collection app model like this:
from accounts.models import ReporterProfile, User
from <project_name> import settings
class Report(models.Model):
reporterprofile = models.ForeignKey(ReporterProfile, on_delete=models.CASCADE, verbose_name="Report Author")
...
class Comment(models.Model):
report = models.ForeignKey(Report, on_delete=models.CASCADE, related_name='comments')
user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE, verbose_name="Comment by")
...
When running the server or makemigrations, I'm getting the error:
File "F:\project_name\accounts\models.py", line 8, in from collection.models import Report
File "F:\project_name\collection\models.py", line 2, in from accounts.models import ReporterProfile, User
ImportError: cannot import name 'ReporterProfile' from partially initialized module 'accounts.models' (most likely due to a circular import) (F:\project_name\accounts\models.py)
I think the error is coming because of wrong importing pattern. What should I do?
For ForeignKey:
Instead of using reporterprofile = models.ForeignKey(ReporterProfile, ...), you can use reporterprofile = models.ForeignKey("accounts.ReporterProfile", ...), so you don't have to import the model.
For preventing circulor import error :
Instead of using :
from accounts.models import ReporterProfile
[...]
foo = ReporterProfile()
You can use:
import accounts.models
[...]
foo = accounts.models.ReporterProfile()
Make sure you are writting the create models nane because I got the same issue and when take a look on my import I wrote userFormdata instead of userformData (I capitalized the 'f')
#wrong inport
from users_handler.models import userFormData
#Correct import
from users_handler.models import userformData
import the models like below
import collection
class ReporterProfile(models.Model):
....
def published_articles_number(self):
num = collection.models.Report.objects.filter(reporterprofile=self.id).count()
return num
similarly
import accounts
from <project_name> import settings
class Report(models.Model):
reporterprofile = models.ForeignKey(accounts.models.ReporterProfile, on_delete=models.CASCADE, verbose_name="Report Author")
...
class Comment(models.Model):
report = models.ForeignKey(accounts.models.Report, on_delete=models.CASCADE, related_name='comments')
user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE, verbose_name="Comment by")
...
