How to define a "has many" reference between models

Please refer to here for general informatios about models.

If you want to define a "has many" reference between models you are creating a Master/Detail relationship. You have to operate in both master and detail model:

• Master model: define the DetailReferences node
• Detail model: define a reference field that points back to the master model.

Example from HelloKitto:

# Party.yaml
ModelName: Party
...
DetailReferences:
  Invitation: Invitation

# Invitation.yaml
ModelName: Invitation
Fields:
...
  Party: Reference(Party) not null
    Fields:
      Party_Id:
