Unfortunately you've missed the same thing that every other person who's said the same thing has missed: Admin forms, fieldsets, and filter_horizontal. Django provides implicit reverse models, but they are not the same, and do not act the same as explicit ManyToMany relationships. I'll be ver

Re: Feature request: Abstract ManyToManyField

A ManyToMany field on one model will automatically place a corresponding field in the other model that provides the reverse lookup. For example, if you have: class HostGroup(models.Model): hosts = models.ManyToManyField('Host', blank=True, null=True, related_name='ho

Maybe it's a too large of a lunch, but I'm not sure how to answer that. A HostGroup object has a relationship to multiple Host objects, and a Host object has a relationship to multiple HostGroup objects. There are also 13 or 14 more sets of paired relationships like that, spread across six o

Does '%(class)s_hosts' represent the reverse relationship of '%(class)s_hostgroup' like: HostGroups <-> Hosts Or is a tree-like structure like: ... <-> HostGroups1 <-> Hosts1 <-> HostGroups2 <-> Hosts2 <-> Where HostGroup2 has a relationship to Hosts1 and a separate relationship to Hosts2?

Nevermind, it would seem as though transactions are only for rolling back or preventing database changes in the case of failures, and provide no other kind of constraints. I'm writing an article on enforcing uniqueness constraints in Django. On Feb 3, 1:19 am, Matteius wrote: > Well OK so it wou

Dropping support for old Python versions in Django 1.4

With Django 1.3 almost out, I would like to ask, what's the current deprecation plan of old Python versions (namely 2.4 and 2.5). The major argument against dropping 2.4 was RHEL support. RHEL6 seems to support Python 2.6 (dunno about CentOS), so is that still a blocker ? As for dropping 2.5, the
