A generic field that can be tied to any arbitrary model field. The `ModelField` class delegates the task of serialization/deserialization to it's associated model field. This field can be used to create serializer fields for custom model fields, without having to create a new custom serializer field.

The `ModelField` class is generally intended for internal use, but can be used by your API if needed. In order to properly instantiate a `ModelField`, it must be passed a field that is attached to an instantiated model. For example: `ModelField(model_field=MyModel()._meta.get_field('custom_field'))`

If you want to create a custom field, you'll probably want to override either one or both of the `.to_native()` and `.from_native()` methods. These two methods are used to convert between the initial datatype, and a primitive, serializable datatype. Primitive datatypes may be any of a number, string, date/time/datetime or None. They may also be any list or dictionary like object that only contains other primitive objects.

|
||||
The `.to_native()` method is called to convert the initial datatype into a primitive, serializable datatype. The `from_native()` method is called to restore a primitive datatype into it's initial representation.
