Re: Multi-table inheritance and primary keys

Hey Torsten,

It looks like you ran into the bug reported as https://code.djangoproject.com/ticket/23956 . See my comment #6 for a workaround.

Hallöchen!

Is it correct that when using multi-table inheritance, I must not
set an explicit primary key in the derived model class?  Currently,
I get

  ...
  File "/usr/local/lib/python2.7/dist-packages/django/db/backends/utils.py", line 65, in execute
    return self.cursor.execute(sql, params)
django.db.utils.ProgrammingError: column "process_ptr_id" of relation "samples_deposition" already exists

while applying the initial migration and wonder whether that what I
try to achive is possible at all.

("samples" is the app name, "deposition" is the model name of the
derived model.)

Tschö,
Torsten.
