* this commit fixes the usage of a CursorPagination combined with a view
implementing an ordering filter, without a default ordering value.
* former behavior was to fetch the ordering value from the filter, and
raises an error if the value was None, preventing the fallback on the
ordering set on the CursorPagination class itself.
* we reversed the logic by getting first the value set on the class,
and override it by the ordering filter if the parameter is present
* Refactor get_field_info method to include max_digits and decimal_places attributes in SimpleMetadata class
* Add new test to check decimal_field_info_type
* Update rest_framework/metadata.py

* Ensure CursorPagination respects nulls in the ordering field
* Lint
* Fix pagination tests
* Add test_ascending with nulls
* Push tests for nulls
* Test pass
* Add comment
* Fix test for django30
* Update relations.py
Currently if you define the slug field as a nested relationship in a `SlugRelatedField` while many=False, it will cause an attribute error. For example:
For this code:
```
class SomeSerializer(serializers.ModelSerializer):
some_field= serializers.SlugRelatedField(queryset=SomeClass.objects.all(), slug_field="foo__bar")
```
The POST request (or save operation) should work just fine, but if you use GET, then it will fail with Attribute error:
> AttributeError: 'SomeClass' object has no attribute 'foo__bar'
Thus I am handling nested relation here. Reference: https://stackoverflow.com/questions/75878103/drf-attributeerror-when-trying-to-creating-a-instance-with-slugrelatedfield-and/75882424#75882424
* Fixed test cases
* code comment changes related to slugrelatedfield
* changes based on pre-commit and removed comma which was added accidentally
* fixed primary keys of the mock object
* added more test cases based on review

Apart from a few exceptions, django-rest-framework uses the American
English spelling "authorization"/"authorized".
$ git grep -oi authorised | wc -l
2
$ git grep -oi authorized | wc -l
30
Replace the few occurences of the British English spelling with the
American English one.
Allow Request, Response, Field, and GenericAPIView to be subscriptable.
This allows the classes to be made generic for type checking.
This is especially useful since monkey patching DRF can be problematic
as seen in this [issue][1].

Without this, Django's ValidationErrors will bypass the error collection
from ListField's children.
Here is an example that illustrates this change.
Consider a Serializer that uses ListField like this:
```python
class SomeSerializer(serializers.Serializer):
uuids = serializers.ListField(
child=serializers.PrimaryKeyRelatedField(
queryset=Model.objects.something(),
validators=[SomeCustomValidator()]
)
)
```
Validating data that looks like this works fine:
```python
{uuids: ['some-valid-uuid', 'some-valid-uuid']}
```
Raising a DRF ValidationError for one of the children works fine, giving
an error object like:
```python
{'uuids': {0: ErrorDetail(string='Some validation error')}}
```
Raising a Django ValidationError for one of the children works
differently (which serializers.PrimaryKeyRelatedField can do in some
cases, like when the uuid is malformed). It gives an error object like:
```python
{'uuids': ["'X' is not a valid UUID."]}
```
Handling Django's ValidationErrors in ListField explicitly (like in this
pull request), will maintain a regular error interface in this case:
```python
{'uuids': {0: ErrorDetail(string="'X' is not a valid UUID.")}}
```
Scripts with type="application/json" or "text/plain" are not executed, so we can
use them to inject dynamic CSRF data, without allowing inline-script execution
in Content-Security-Policy.

Importing anything `rest_framework` causes `django.test` to be imported.
This is because DRF registers a receiver on the
`django.test_signals.setting_changed` signal.
This is not really a problem, but it is good to avoid this because it
bloats the memory with unnecessary modules (e.g. `django.test`,
`django.core.servers.basehttp`, `socketserver`) and increases the
startup time. It also doesn't feel right to import test code into
non-test code.
Try to import the signal from a core module if possible.
Note that there's another `django.test` import in `MultiPartRenderer`,
however this import is done lazily only if the functionality is used so
can be easily avoided.
`PendingDeprecationWarning` means "we plan to deprecate, but haven't
yet." A feature that's to be deleted in the next release is not planned
to be deprecated; it **is** deprecated.
> Base class for warnings about features which are obsolete and expected
> to be deprecated in the future, but are not deprecated at the moment.
>
> This class is rarely used as emitting a warning about a possible
> upcoming deprecation is unusual, and DeprecationWarning is preferred for
> already active deprecations.
