# Eagle Estates - Part 14

# To-Do's

  • Add a computed integer field room_count to the eagle.property model.
  • The compute method should calculate the number of rooms from the length of room_ids field.
  • In the form view of eagle.property, remove the existing room_ids field.
  • Add a smart button inside the sheet element and add the computed integer field as a stat and an appropriate fontawesome icon.
  • Add a Python method that returns an action to open the list view of the rooms.
  • Add a button labeled Create Room inside the header element of the form view.
  • Add a Python method that returns an action to open the form view of eagle.property.room.
  • Disable creation of eagle.property.room records from its views by adding create="false" to the list element.

# Notes

  • When viewing rooms, we should add a domain in the action to filter rooms by the current property.
  • Similarly, when creating a new room, we should set a default value for the property_id field. This can be done by adding a context key to the action that opens the view.
