How to define a "has many" reference between models

Please refer to here for general informatios about models.

If you define an "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 listing details references
• Detail model: define a reference field that points back to the master model.

Example from HelloKitto:

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

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