Complex Forms with Multiple Models

In complex user interfaces it can happen that a user has to fill in data in one form that has to be saved in different tables in the database. The concept of Yii forms allows you to build these forms with nearly no more complexity compared to single model forms.

1. instantiate model classes
2. populate the models attributes with input data
3. validate all models
4. If validation passes for all models, save them
5. If validation fails or no data has been submitted, display the form by passing all model instances to the view
