Preventing django from appending "_id" to a foreign key field
Question:
In django, if I set a field in a model to a foreign key, "_id" is appended to the name of that field. How can this be prevented?
Answers:
When using the foreign field in a model, Django creates two fields: One for the actual link, and one that references the other model.
class A(Model):
i = IntegerField()
class B(Model):
a = ForeignKey(A)
In B there is now two fields: a and a_id. a_id is the unique id as stored in the database, while a can be used to directly access the fields in A, like this:
b = B.objects.get(...)
b.a.i = 5; # Set the field of A
b.a.save() # Save A
You can set the field’s db_column attribute to whatever you’d like.
