DRF：使用序列化器字段“字段”

Question

I want to use a serializer having the field fields :

class MySerializer(Serializer):
    fields = CharField(required=True)

But Serializer class already has a method named fields . So there is ambiguity in using this attribute of the instance and class, which can lead to errors and mess up with static analyzers:

>>> a = MySerializer()
>>> a.fields
{'fields': CharField(required=True)}

>>> MySerializer.fields
<django.utils.functional.cached_property object at 0x543543215670>

So, I wonder, is there the way to declare a serializer class with an alias like:

class MySerializer(Serializer):
    fields_ = CharField(required=True, alias='fields')

The important part is to make it able to parse input data with the alias fields :

>>> a = MySerializer(data={'fields': 'some text'})
>>> a.is_valid()
True

>>> a.validated_data
OrderedDict([('fields', 'some text')])

Try using ModelSerializer, it should work.

class MySerializer(serializers.ModelSerializer):

    class Meta:
        model = Your Model Class Name
        fields = ('fields',)
        # or use fields = '__all__'
