Thanks for your answer. I have one more question. What if there are more than one primary keys in that table?

By definition, that won't happen, a primary key is unique. If you add a record with the same key Django will raise an IntegrityError.

 

I'm talking about the unique_together case.

I don't understand you

What Django shows in that dropdown is the __str__() method of the object, define it to your needs in A :)

Hello. I have two models. In one of them, I declared a foreign key to the other one. Since this is done in Django by only specifying the Class name, without specifying the field name(column name), when I try to create an object in admin panel, it pulls the wrong column information.

Two models A and B.

B has a Foreignkey for accessing A.

A has two fields Field1 and Field2.

When I try to create an instance of B, in the field of Foreignkey, there is a drop down menu but the content is not from the right field of A.

How to specify it?
