    A read-only field that simply returns the field value.

    If the field is a method with no parameters, the method will be called
    and its return value used as the representation.

    For example, the following would call `get_expiry_date()` on the object:

    class ExampleSerializer(Serializer):
        expiry_date = ReadOnlyField(source='get_expiry_date')

    A hidden field does not take input from the user, or present any output,
    but it does populate a field in `validated_data`, based on its default
    value. This is particularly useful when we have a `unique_for_date`
    constraint on a pair of fields, as we need some way to include the date in
    the validated data.

ÚSerializerMethodFieldaÆ  
    A read-only field that get its representation from calling a method on the
    parent serializer class. The method called will be of the form
    "get_{field_name}", and should take a single argument, which is the
    object being serialized.

    For example:

    class ExampleSerializer(Serializer):
        extra_info = SerializerMethodField()

        def get_extra_info(self, obj):
            return ...  # Calculate some data to return.

ModelFieldzÓ
    A generic field that can be used against an arbitrary model field.

    This is used by `ModelSerializer` when dealing with custom model fields,
    that do not have a serializer field to be mapped to.
