Get name of primary field of Django model
Solution 1:
You will also have an attribute "name" on the pk-attribute. This seems to hold the name of the Field.
CustomPK._meta.pk.name
In my case I get the value "id" as result (like it should). :-)
Solution 2:
Field objects have a primary_key attribute
for field in CustomPK._meta.fields:
print field.primary_key
print field.name
# True
# primary
# False
# payload
