* Removed type coercion. Options created by argparse are already coerced
to the correct type.
* Removed fallback default values. Options created by argparse already
have a default value.
* Used direct indexing. Options created by argparse are always set. This
eliminates the need to use dict.get().
Field.rel is now deprecated. Rel objects have now also remote_field
attribute. This means that self == self.remote_field.remote_field.
In addition, made the Rel objects a bit more like Field objects. Still,
marked ManyToManyFields as null=True.
The new signature enables better support for routing RunPython and
RunSQL operations, especially w.r.t. reusable and third-party apps.
This commit also takes advantage of the deprecation cycle for the old
signature to remove the backward incompatibility introduced in #22583;
RunPython and RunSQL won't call allow_migrate() when when the router
has the old signature.
Thanks Aymeric Augustin and Tim Graham for helping shape up the patch.
Refs 22583.
This allows specifying ForeignKeys in REQUIRED_FIELDS when using a
custom User model.
Thanks cjerdonek and bmispelon for suggestion and timgraham for review.
This option is not actually very useful in the general case
because it doesn't override sys.stdin.
It's still marginally useful for testing some features of
the createsuperuser command so it was moved there.
This commit also makes the detection of a TTY in createsuperuser
a bit more robust, after a suggestion of appolo13.
This is the result of Christopher Medrela's 2013 Summer of Code project.
Thanks also to Preston Holmes, Tim Graham, Anssi Kääriäinen, Florian
Apolloner, and Alex Gaynor for review notes along the way.
Also: Fixes#8579, fixes#3055, fixes#19844.
Returning None on errors required unpythonic error checking and was
inconsistent with get_app_config.
get_model was a private API until the previous commit, but given that it
was certainly used in third party software, the change is explained in
the release notes.
Applied the same change to get_registered_model, which is a new private
API introduced during the recent refactoring.
* Introduced [un]set_installed_apps to handle changes to the
INSTALLED_APPS setting.
* Refactored [un]set_available_apps to share its implementation
with [un]set_installed_apps.
* Implemented a receiver to clear some app-related caches.
* Removed test_missing_app as it is basically impossible to reproduce
this situation with public methods of the new app cache.
Since the original ones in django.db.models.loading were kept only for
backwards compatibility, there's no need to recreate them. However, many
internals of Django still relied on them.
They were also imported in django.db.models. They never appear in the
documentation, except a quick mention of get_models and get_app in the
1.2 release notes to document an edge case in GIS. I don't think that
makes them a public API.
This commit doesn't change the overall amount of global state but
clarifies that it's tied to the app_cache object instead of hiding it
behind half a dozen functions.
Added a validation error check when creating the permissions for model, to avoid
cryptic database error when the verbose_name is longer than 39 characters
