MySQL:To fremmednøgler i en tabel, der henviser til en anden tabel

Og her går vi:Du har angivet de samme aliaser for relationerne.

User:
  relations:
    viewed_by: 
       class: View
       local: user_id
       foreign: viewed_id
       type: many
       foreignType: one
       foreignAlias: viewed

    viewed:
      class: View
      local: user_id
      foreign: viewer_id
      type: many
      foreignType: one
      foreignAlias: viewer

Eller du sætter hele mange-til-mange-relationen anderledes op:

User:
   relations:
     viewed_by: 
       class: User 
       local: viewed_id
       foreign: viewer_id,
       refClass: View
     viewed:
       class: User
       local:viewer_id
       foreign: viewed_id
       refClass: View

og View skal se ud

View:
  columns:
    viewed_id:
      type: integer
      primary: true
    viewer_id:
      type: integer
      primary: true
