#23624: Regression in ManyToManyField with through, runtime-generated models
----------------------------------------------+--------------------
Reporter: ludoo | Owner: nobody
Type: Bug | Status: new
Component: Database layer (models, ORM) | Version: 1.7
Severity: Normal | Keywords:
Triage Stage: Unreviewed | Has patch: 0
Easy pickings: 0 | UI/UX: 0
----------------------------------------------+--------------------
I admit my situation is a corner case: an app interfacing with a legacy
db, where I need to extend an abstract model to contextualize it to
identical tables, named differently (eg obj_1 table, obj_2 table, etc.),
and to make things worse the number of tables is only known at runtime.
I am then dynamically generating a module for each set of models, and
while things work great in Django 1.6, in 1.7 ManyToManyField using a
through model breaks.
I am attaching a sample models.py file that illustrates the issue. I have
not yet found the time to delve into what's happening, I hope someone with
a better understanding of all the related stuff steps in as it's something
I have never looked into.
