This can be used if the widget returns null, but there is a default instance value which should not be overwritten. :param dehydrate_method: You can provide a `dehydrate_method` as a string to use instead of the default `dehydrate_{field_name}` syntax, or you can provide a callable that will be executed with the instance as its argument. :param m2m_add: changes save of this field to add the values, if they do not exist, to a ManyToMany field instead of setting all values. Only useful if field is a ManyToMany field.
