Add filtering against uid

[Souleymane-T]

All filters can be used against the uid field

/api/v1.1/my-model/?uid__in=xxx,yyy for example.

[KhaledBousrih]

You must check that the values in the uid__in=<list_values> are all valid UUIDs.

For example this /api/v1.1/item/?uid__in=test1,test2 raises a 500 ValidationError with as message: ["'test1' is not a valid UUID."]

example of check to be set in the FilterSupportingOrBackend class:

if isinstance(
    queryset.model._meta.get_field(param.replace('__in', '')),
    UUIDField,
):
    for value in values:
        try:
            uuid.UUID(value)
        except ValueError:
            raise ValidationError(
                {
                    "message": (
                        f"{param}: {value} is not a valid UUID"
                    )
                }
            )
