#11148: Inline Views don't support editable=False for PK value
---------------------------------------+------------------------------------
Reporter: [email protected] | Owner: nobody
Status: new | Milestone: 1.1
Component: django.contrib.admin | Version: SVN
Keywords: | Stage: Unreviewed
Has_patch: 0 |
---------------------------------------+------------------------------------
When saving the ''second'' record of a !ManyToMany relationship via the
Admin forms using an intermediate model with the pk field parameter of
editable=False in the xref table throws this error:
/usr/lib/python2.5/site-packages/django/forms/models.py in
save_existing_objects, line 621 !KeyError (None)
Steps to reproduce:
* using the models.py provided below generate your db models (I'm using
Postgres).
* Create a few Entries, Blogs, Authors (manually enter the PK values as
made up integers)
* Using the Inline Entry view of the Authors Add Record screen and
attempt to link two Entries to a single author.
* The first entry will save, the second will throw the error above
(!KeyError)
