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.
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
* 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.
* 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
* 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().

* Always exclude read_only fields from _writable_fields
* Remove `read_only` from `CreateOnlyDefault` example.
In this context (without mentioning `save`) now slightly misleading.
Calling dict.keys() is unnecessary. The two are functionally equivalent
on modern Pythons.

Set literals are available on all supported Python versions. They are
idiomatic and always faster:
$ python3 -m timeit '{}'

$ python3 -m timeit 'dict()'
10000000 loops, best of 3: 0.104 usec per loop
$ python3 -m timeit '{1, 2, 3}'
10000000 loops, best of 3: 0.0754 usec per loop
$ python3 -m timeit 'set([1, 2, 3])'

JSONField now always available.
* Remove DecimalValidator compat

Plus isort.
* Remove set_many compat
* Remove include compat
Per issue #4999, JSONFields are not rendered properly in the DRF
browsable API HTML forms. This patch attempts to fix that behavior by
introducing a JSONBoundField helper similar to the NestedBoundField
helper.
