How to define a "Has Many" reference between models

Please refer to here for general information about models.

If you define a "Has Many" reference between models, you are creating a Master/Detail relationship. You have to operate in both master and detail models:

  • Master model: define the DetailReferences node listing detail 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:

In order to render the master/detail relationship between data, you have to define the MainTable/DetailTables node in the view as following:

# view parties
Type: Data
...
MainTable:
  Model: Party
.......
  DetailTables:
    Controller:
      # Tabs/Popup/Bottom. Default = Tabs.
      Style: Bottom
        Height: 250
    Table:
      Model: Invitation
      Fields:
        Invitation_Id:
        Party:
          IsVisible: False
        Invitee:
        Accepted:
