Django Object Manager Problem -

So here's a question for a Django wizard. I inherited the object manager in some way with lines:

  class MyObjManager (models.Manager): def total_values ​​(self, myobj_id): return 49 def what_the_heck (manually , Poll_id): return 48 square TestMe (): def what_the_heck (self, poll_id): return 47  

Now if I make a model that uses this object manager, then work as follows does not.

MyObj (models.Model): x = models.CharField (max_length = 200) y = Model. Dataimfield ('Date published') objects = MyObjManager () kb = MyObjManager () testMe = TestMe () DRF all_values ​​(self): # Return one self.objects.total_values ​​(1) #b Return self.objects.yyy (1) # Returns C.B.V.H_HEKAQ (1) #D Returns 50 # A Return Self TestMe.what_the_heck (1) #f Returns self.objects.what_the_heck (1)

Now it seems that A, B, C, D, E are at one time Respectively made a comment. Here are the results if I call myObj.total_values. (Where MyObj is an example of MyObj) A) Nothing B) Nothing C) None D) 50 E) 47 F) Nothing

I used two Object Managers in this example But it does happen that I only use one, why can not I use methods in my underlying object management manager? , B, and C. You can not use yourself ... This is an example method, and itself refers to that example ... in which an example does not have manager methods.

E and F work because, once again you are calling example methods, of which you have declared the properties properly.

For A, B, C, MyObj

  class MyObj (model): x = model.ccarfield (max_length = 200) y = model.Datetime field ( 'Publish Date') Objects = MyOzJanager () KB = MyOnJenner () testMe = TestMe () DRF total_value (auto): # Return MyOs .objects.total_values ​​(1) #B Return MyObj.objects.yyy (1) # C return MyObj.kb.what_the_heck (1) #D return 50 # Back Self Test. Me what_the_heck (1) #f return self.objects .what_the_heck (1)  

me ah It's time to think about the scenario, where you An example of the model will be found, and then call a function to get other examples of that model, though ... (I suggest that your approach may be weird or wrong, your big scope problem gives you better answers Can help.)
