In short: for some of these fake relations table fields were generated for both sides instead of table field on one side and view field on another. What had to be done:

• Updated sql:
  • added reference for some fields, removed it from the others
  • added required for some fields
  • to avoid setting these required fields for testing the other fields, moved them to the new collections (fake_model_d and fake_model_e)
• Regenerated Fake models
• Updated set_models() where it used to set values for both sides (it was possible because we had table fields on both sides)
