Hey there,
here’s a little topic that impacts the usability of Django admin’s delete
views.
When deleting an object using django admin, you get a nice summary of all
deleted objects.
I really like the overview, but the labels used to describe m2m relations
that will be deleted aren't user-friendly at all:
[…]
- MediaItem-subseries-relation: MediaItem_sub_series_relation object
(11482)
- MediaItem-piece-relation: MediaItem_pieces_relation object (11773)
So I’d like to improve the labels a bit, using the from and to model’s
verbose names. This can be easily accomplished by changing
`create_many_to_many_intermediary_model` in fields/related.py.
To be honest, I don’t know how to update the tests for something rooted
deeply in Django’s core.Is anyone who is more competent than me interested
in fixing this? It would greatly improve the “delete confirmation“ views.
Here’s what I’ve got so for; it only fixes the model’s verbose name, not
its string presentation.
Best regards
Julian

if isinstance(to_model, str):
to_label = to
to_label_plural = to

to_label = to_model._meta.verbose_name
to_label_plural = to_model._meta.verbose_name_plural
from_label = klass._meta.verbose_name
from_label_plural = klass._meta.verbose_name_plural
if to == from_:
to = 'to_%s' % to
from_ = 'from_%s' % from_
meta = type('Meta', (), {
'db_table': field._get_m2m_db_table(klass._meta),
'auto_created': klass,
'app_label': klass._meta.app_label,
'db_tablespace': klass._meta.db_tablespace,
'unique_together': (from_, to),
'verbose_name': _('%(from)s-%(to)s relationship') % {'from':
from_label, 'to': to_label},
'verbose_name_plural': _('%(from)s-%(to)s relationships') %
{'from': from_label_plural, 'to': to_label_plural},
'apps': field.model._meta.apps,
})
