Re: writing most common queries as model class method!

Hey Amir,

Django best practice is to put all common query methods in the model manager class instead of the model class itself.

Hi, 

I tried to write a classmothods/ instance method in a Model in order to run most common query from the model but got errors like below :

""AttributeError: Manager isn't accessible via ... instances""

example code:

class Profile(model.Model):

    name = model.Charfield(...)

    address = model.Charfield(...)

    ....

    @classmethod

     def count_of_users(cls):

           return cls.objects.all()  #example query

     def all_users(self):

          return self.objects....

My purpose is to have most common and important queries in a method to be called within application. (Its a good way for documenting most common queries as well).What is the best practice for this case?
