 This is a read-only field.  It gets its value by calling a method on the serializer class it is attached to.  It can be used to add any sort of data to the serialized representation of your object.  The field's constructor accepts a single argument, which is the name of the method on the serializer to be called.  The method should accept a single argument (in addition to `self`), which is the object being serialized.  It should return whatever you want to be included in the serialized representation of the object.  For example:
