#fields(*field_names, &block) ⇒ Object
Returns all field configurations for the model configuration instance. If no fields have been defined returns all fields. Defined fields are sorted to match their order property. If order was not specified it will match the order in which fields were defined.
If a block is passed it will be evaluated in the context of each field
