Django 3.1 adds a new generic JSONField to replace the PostgreSQL-specific one. This adds support for the new field type, which should behave the same as the existing PostgreSQL field.
Django's new JSONField also includes support for a custom "decoder", so add support for that in the serializer field.
* Make `NullBooleanField` subclass `BooleanField`
This removes a lot of the redundancy that was in place becuase we
were not doing this. This maintains the `None` initial value that
was previously present, as well as disallowing `allow_null` to be
passed in.
* Remove special case for mapping `NullBooleanField`
In newer versions of Django, the `NullBooleanField` is handled the
same way as a `BooleanField(null=True)`. Given that we also support
that combination, and that our own `NullBooleanField` behaves in the
same manner, it makes sense to remove the special casing that exists
for it.
* Add test for BooleanField(null=True, choices)
* Remove special case for NullBooleanField
* Adjust mapping tests for NullBooleanField
* Fixed linting error
* Raise deprecation warning when NullBooleanField is used
* Fix linting issue in imports
* Fix ModelSerializer unique_together field sources
Updates ModelSerializer to check for serializer fields that map to the
model field sources in the unique_together lists.
* Ensure field name ordering consistency
* SearchFilter to support Custom query Transforms
Since Some fields support `__` as a custom Transform for query lookups we needed to update the m2m checking code to handle search_fields that contain __ that are not relationships.
* Update documentation on SearchFilter to include references to JSON and HStore Fields.
Previously it was only mapping the `type` and `format`, even though
for some field types (like a `MultipleChoiceField`) we map more
than just these. And for some fields (like a `ChoiceField`) we do
not map the `type` at all.
* serializers: removes no longer needed compat checks
UUIDField and DurationField are both supported in all supported Django
versions.
IPAddressField was removed in Django 1.9, which is no longer supported.
* serializers: move related code closer together
This way it's easier to see all of the mappings in one place.
* serializers,docs: remove some DRF 2.x references
The last release of DRF 2.x was 5 years ago, it seems fine to remove
these references now.
* Version 3.11
* Added notes on OpenAPI changes for 3.11.
* Minor docs tweaking
* Update package version and supported versions
* Use a lazy import for django.test.client.encode_mutlipart. Closes#7078
* Expand declared filtering tests
- Test declared filter ordering
- Test multiple inheritance
* Fix serializer multiple inheritance bug
* Improve field order test to check for field types
* Raise framework-specific deprecation warnings
- Use `RemovedInDRF313Warning` instead of DeprecationWarning
- Update to follow deprecation policy
* Pass serializer instead of model to validator
The `UniqueTogetherValidator` may need to access attributes on the
serializer instead of just the model instance. For example, this is
useful for handling field sources.
* Fix framework deprecation warning in test
* Remove outdated validator attribute

This provides a way for pagination classes to add pagination properties (`count`, `next`, `results` etc.) to OpenAPI response schemas.
A new method `get_paginated_response_schema()` has been added to `BasePagination`. This method is intended to mirror `get_paginated_response()` (which takes a `list` and wraps it in a `dict`).
Hence, `get_paginated_response_schema()` takes an unpaginated response schema (of type `array`) and wraps that with a schema object of type `object` containing the relevant properties that the pagination class adds to responses.
The default implementation of `BasePagination.get_paginated_response_schema()` simply passes the schema through unmodified, for backwards compatibility.
This is the first part of #6846.
Previously, the response schema for list views was an object representing a single item. However, list views return a list of items, and hence it should be an array.
Further work will need to be done to support how pagination classes modify list responses.
There should be no change for views not determined to be list views.

* Add tests for raise_errors_on_nested_writes
* Fix dotted-source field checking on serializer write
The code was previously checking the validated data for the field's
attribute name, however, the data contain the first source attr.
Refs #6509
This enforces allow_empty=True when a ListSerializer is a child of another serializer and partial validation is being performed on the parent serializer.
This is because partial validation should allow fields to be omitted, but should not cause values that are invalid without partial validation to become valid.
This effectively reverts #4222. None of the tests added in that PR fail if the associated change is removed, so I‘m not sure what that PR was trying to fix.
* fixes#6751
* reverted condition
* save instance before setting m2m fields
* added comment why m2m fields are saved after instance
* removed blank line
* added test for the issue 6751
It might be useful for a serializer with many many fields which uses
read_only and write_only on a large percentage of the fields. But the
memory usage and statefulness it adds are not worth it for the common
case.

On Python 3, the ugettext functions are a simple aliases of their non-u
counterparts (the 'u' represents Python 2 unicode type). Starting with
Django 3.0, the u versions will be deprecated.
https://docs.djangoproject.com/en/dev/releases/3.0/#id2
> django.utils.translation.ugettext(), ugettext_lazy(), ugettext_noop(),
> ungettext(), and ungettext_lazy() are deprecated in favor of the
> functions that they’re aliases for:
> django.utils.translation.gettext(), gettext_lazy(), gettext_noop(),
> ngettext(), and ngettext_lazy().

* Introspect ManyRelatedField data type recursively
For all `ManyRelatedField` objects, we were assuming that the inner type was always a `String`. While this may be true for the default output, a `ManyRelatedField` is a wrapper for a lot of other classes which includes more than just strings. This should allow us to document lists of things other than strings.
* Added test for schemas for many-to-many fields
This adds a test that makes sure we generate the schema for a many-to-many field such that it actually has the right type. For some reason we did not previously have any tests for schema generation that included them, so hopefully this will prevent any future issues from popping up.
This should serve as a regression test for the `items` field on to-many relationships, which was previously forced to a `String` even though in most cases it is a different inner type within the array.
As all source files import unicode_literals, type('') is always
equivalent to six.text_type (str on Python 3 and unicode on Python 2).
Removes the need to call type(), is more explicit, and will be easier to
catch places to change for when it is time to eventually drop Python 2.
* Use compat version of collections.abc.Mapping
Since the Mapping class will no longer be available to import directly
from the collections module in Python 3.8, we should use the
compatibility helper introduced in #6154 in the fields module.
* Alias and use compat version of collections.abc.MutableMapping
Since the MutableMapping class will no longer be available to import
directly from the collections module in Python 3.8, we should create an
alias for it in the compat module and use that instead.

Trying to register new routes on a router after having accessed the
router `urls` attribute leads to surprising results.
The route is added without error to the router's `registry` but the urls
are not updated, because they are cached in `_urls`.
This commit invalidates the cache after each new registration.
