Propagate the nullability of underlying model fields in ModelSerializer
when those fields are marked as read only. This ensures the correct
generation of OpenAPI schemas.
Fix#8041.
* Add distinction between request and response serializers
* Add docs
* document new functions in schemas.md
* add a test case for different request vs response objects
* Correct formatting for flake8

HTML responses generated by the Browsable API otherwise generate
inconsistent ETAGs -- due to the presence of CSRF tokens in the response
-- even when the API is read-only, (and as such when the response
contains no resource-modifying forms, i.e. neither POST nor PUT forms,
which might require the CSRF token).
While the template was appropriately including CSRF tokens only within
POST and PUT forms, its AJAX overlay included the CSRF token in *every*
response, regardless of whether it would be needed.
This change brings the logic of the `script` block into line with that
of the rest of the template -- and such that read-only APIs (and really
the Browsable API pages of *any* read-only resources) will not
needlessly include the CSRF token, and will now be safely cachable -- by
both back-end systems and by the user agent.
* Add failing tests for ordering filter with model property
* Fix get_default_valid_fields of OrderingFilter
* Filter model properties in get_default_valid_fields of OrderingFilter
* Fix JSONBoundField usage on nested serializers (#6211)
* Unify JSONBoundField as_form_field output between py2 and py3
When using json.dumps with indenting, in python2 the default formatting
prints whitespace after commas (,) and python3 does not. This can be
unified with the separators keyword argument.
* Add failing test when rendering to json a schema with timedelta
* Fix JSONOpenAPIRenderer for fields with default=timedelta()
* fix isort
* fix test for python 3.5

* Handle None in to_representation()
* Return None as '' in to_representation() when coerce_to_string=True
* Handle '' as None in to_internal_value(), for symmetry with
to_representation(), and because the empty concept doesn't make sense
for Decimal.

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
* Pass data via response instead of renderer_context
Instead of relying on internal implementation details to get a reference
to the response or view, attach these directly to the returned response.
* Remove unused method
* 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.
