Adding new field types to a schema

[Matthew Scott]

You can add new field types to a schema by creating a subclass of the field class you wish to extend, or by subclassing Field itself for a completely new data type.  Remember to grab field classes from the F namespace in the schema:

    class MySpecialFloat(F.Float):

        # ... implementation ...

When creating entities using the new type, use the lowercase_with_underscores version of the class name:

    class MyEntity(E.Entity):

        position = f.my_special_float()

Here's an example based loosely on an actual custom field used in a commercial app:
