This was triggered by r8794, but was, in fact, fairly fragile before then. The
current fix is the correct way we should be doing this.

sometimes also sharing aliases, instead of creating their own. This was
generating incorrect SQL.
No representative test for this fix yet because I haven't had time to write one
that fits in nicely with the test suite. But it works for the monstrous example
in #8790 and a bunch of other complex examples I've created locally. Will write
a test later.

manager aren't inherited). Based on some patches from sebastian_noack and
emulbreh.

I can't reproduce the original error leading to #8115 and the patch. However, the only harm this change could cause is to raise more `CyclicDependency` exceptions than strictly necessary. That's better than infinite loops, at least, and it's easier to clean up in the future when we figure out the actual fix.

(e.g. the admin filtering).
Not an ideal solution to the problem, but will do the job for the time being.

Backwards incompatible if you are using manually-specific primary key values
and relying on the previously documented behaviour that the new values would
always exist in the database (i.e. it would update the existing entry).

Also comes with approximately 67% less stupidity in the table joins for
filtering on generic relations.

* Removed `Manipulator`, `AutomaticManipulator`, and related classes.
* Removed oldforms specific bits from model fields:
* Removed `validator_list` and `core` arguments from constructors.
* Removed the methods:
* `get_manipulator_field_names`
* `get_manipulator_field_objs`
* `get_manipulator_fields`
* `get_manipulator_new_data`
* `prepare_field_objs_and_params`
* `get_follow`
* Renamed `flatten_data` method to `value_to_string` for better alignment with its use by the serialization framework, which was the only remaining code using `flatten_data`.
* Removed oldforms methods from `django.db.models.Options` class: `get_followed_related_objects`, `get_data_holders`, `get_follow`, and `has_field_type`.
* Removed oldforms-admin specific options from `django.db.models.fields.related` classes: `num_in_admin`, `min_num_in_admin`, `max_num_in_admin`, `num_extra_on_change`, and `edit_inline`.
* Serialization framework
* `Serializer.get_string_value` now calls the model fields' renamed `value_to_string` methods.
* Removed a special-casing of `models.DateTimeField` in `core.serializers.base.Serializer.get_string_value` that's handled by `django.db.models.fields.DateTimeField.value_to_string`.
* Removed `django.core.validators`:
* Moved `ValidationError` exception to `django.core.exceptions`.
* For the couple places that were using validators, brought over the necessary code to maintain the same functionality.
* Introduced a SlugField form field for validation and to compliment the SlugField model field (refs #8040).
* Removed an oldforms-style model creation hack (refs #2160).

This isn't a complete solution to this class of problem, but it will do for
1.0, which only has generic relations as a multicolumn type. A more general
multicolumn solution will be available after that release.

means filters on the join table (for ManyToManyField(through=...)) and complex

Also made savepoint handling easier to use when wrapped around calls that might
commit a transaction. This is tested by the get_or_create tests.

* Support for representing files as strings was removed. Use `django.core.files.base.ContentFile` instead.
* Support for representing uploaded files as dictionaries was removed. Use `django.core.files.uploadedfile.SimpleUploadedFile` instead.
* The `filename`, `file_name`, `file_size`, and `chuck` properties of `UploadedFile` were removed. Use the `name`, `name`, `size`, and `chunks` properties instead, respectively.
* The `get_FIELD_filename`, `get_FIELD_url`, `get_FIELD_size`, and `save_FIELD_file` methods for Models with `FileField` fields were removed. Instead, use the `path`, `url`, and `size` attributes and `save` method on the field itself, respectively.
* The `get_FIELD_width` and `get_FIELD_height` methods for Models with `ImageField` fields were removed. Use the `width` and `height` attributes on the field itself instead.
* The dispatcher `connect`, `disconnect`, `send`, and `sendExact` functions were removed. Use the signal object's own `connect`, `disconnect`, `send`, and `send` methods instead, respectively.
* The `form_for_model` and `form_for_instance` functions were removed. Use a `ModelForm` subclass instead.
* Support for importing `django.newforms` was removed. Use `django.forms` instead.
* Support for importing `django.utils.images` was removed. Use `django.core.files.images` instead.
* Support for the `follow` argument in the `create_object` and `update_object` generic views was removed. Use the `django.forms` package and the new `form_class` argument instead.

Though some attempts and backwards-compatibility were made, speed trumped compatibility. Thus, as usual, check BackwardsIncompatibleChanges for the complete list of backwards-incompatible changes.
Thanks to Jeremy Dunck and Keith Busell for the bulk of the work; some ideas from Brian Herring's previous work (refs #4561) were incorporated.
Documentation is, sigh, still forthcoming.
Fixes#6814 and #3951 (with the new dispatch_uid argument to connect).

* Model init no longer performs a database query to refetch the related objects it is passed.
* Model init now caches unsaved related objects correctly, too. (Previously, accessing the field would raise `DoesNotExist` error for `null=False` fields.)
* Added tests for assigning `None` to `null=True` `ForeignKey` fields (refs #6886).

Fixed#7488 (all the debugging there was done by Brian Rosner, who narrowed it
down to the item in this patch).

not required, by default), set the default properly in the constructor.
This code can be simplified when/if we resolve the
BooleanField/NullBooleanField overlap, but the current stuff is backwards
compatible. This would previously cause SQL errors on PostgreSQL and
interesting failures in subtle ways on MySQL and SQLite.

It turns out that we need to treat filename creation/display (in
particular, the upload_to path) differently depending upon whether the value is
out of the database or provided by other code and there's no reliable way to
determine that at the moment (although some later proposed changes might alter
that). So calling get_FIELD_filename on an unsaved model with a changed file
attribute will not necessarily return the same result as after the save().

This is a backward incompatible change. The admin contrib app has been
refactored. The newforms module has several improvements including FormSets
