I have a very basic question about django.db.models.

In this official django tutorial, if you search for word \"choice_set\", you will see tha

Answer 1

In the Document you are referring https://docs.djangoproject.com/en/1.2/intro/tutorial01/#intro-tutorial01

'_set' refers to the all the choices that relates to the Poll object, Since the Choice model has poll that is a Foreign Key to Poll of ID.

For Example:

Consider Poll table row(1,'How are you?','2014 7 3')

and Choice table

when you say

p = Poll.objects.get(id=1)

//now p is a Poll Object that holds <1,'How are you?','2014 7 3'> p.choice_set.create(choice="1st",votes=8) // in Choice table it creates a row that refers poll ID 1 i.e Choice table row(1,1,'1st',8)

Basically _set refers to the tuples of the Choice table (poll) referring Poll table (ID)
