Exclude from Meta is not working when you use an explicit serializer

[Silviu-Surcica]

class Item(Document):
    name = StringField(max_length=255, required=False)
    units = ListField(ReferenceField(Unit))

class BasicUnitSerializer(DocumentSerializer):
    class Meta:
        model = Unit
        fields = ('unit_id', 'name', )
        depth = 1
        verbose = 'unit'
        verbose_plural = 'units'

class ItemSerializer(DocumentSerializer):
    units = BasicUnitSerializer(many=True, required=False)
    class Meta:
        model = Item
        exclude = ('units', )
        verbose_plural = 'items'
        depth = 1

If I use BasicUnitSerializer for units, the exclude does not work. But if I let units be serialized by a default NestedSerializer, then the exclude works.

Hi, thanks for reporting an issue!

Yep, fields and exclude attributes of Meta don't take into account explicitly declared fields.

I'll check if that's inconsistent with pure DRF, and if so, will create tests and fix this.
