writing most common queries as model class method!

[Amir Jamshidi]

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?*
