[Joseph Amiri]

Hi guys. i have a property in my model like blew:

*def is_subscription(self):*

* return self.subscriptions.active().count() > 0*

and it check if course is subscription or not by reverse relation to 
subscription model.

I am expecting quick response from you guys



You cannot expect a quick response or even a response at all if you 
cannot be bothered to take the time to write a proper question yourself.


This might help solve your problem:

Remember that Django is a Python framework, so circular imports are 
mostly a Python thing not specific to Django:

Re: Error : Circula import

[Jet Ezra]

But the link tells you the details and how to solve the problem.
Anyway, I think you forgot to share the said screenshots. I can't find them.

Also, when you are asking please, don't try to direct us how we should
solve this problem. Just detail your problem and wait for your answer.

Simple.
A circular import happens when you have fileA that has something say a
class A, then another file B with also a class B
Then class A imports class B from file B which is also importing class A
from B.
So the program keeps importing and never completes the cycle.

Solution,
If you have to use the two like that, then put them in the same file. It is
always my shortcut.
