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.

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
Use of PyYAML's yaml.load function without specifying the Loader
parameter has been deprecated, see https://msg.pyyaml.org/load.
Earlier versions of PyYAML already had the alternative safe_load
function, which limits the loader to a subset of YAML constructs, that
is enough for what we need here.
Fixes#6677
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.

> 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().
