Cakephp: Designpattern for creation of models in hasMany relationship
- by Chris
I have two Models: Car and Passenger.
Car hasMany Passenger
Passenger belongsTo Car
I managed to create add functionailty for each model and managed to resolve the hasMany relationship between them.
Now I'm trying to create a addCar function and view that allows the user to create a new car and automatically generate Passengers.
I thought of something like this
The view asks the user enter the car information
The view has some field that allows to temporarly add new passengers and remove remove them
When the user saves the new car, the entities for the passengers are created, the entity for the car is created and the passengers are linked to the car.
If the user decides to cacnel everything, the DB remains unchanged.
Now my question is: What is the best way to do this? Is there a pattern / tutorial to follow for such a entity and associated subentity creation?
To clarify: The passengers associated with each car do not exist prior to the existence of the car.
