Eagle Estates - Part 9

Let's add the following features to our app:

• Add a street, zip, city, state_id and country_id fields on the Properties model. You can take inspiration from the res.partner model
• Add the same fields on the Rooms model, but make them related to the fields defined on the related property
• Add a construction_date field on the rooms, should be related to the property's construction_date
• Add an age field on the property, should be set whenever the construction_date changes/is set
  • You can either do this through a compute field, or an onchange function
• Make the area field on the Properties computed (stored), taking the sum of the area of all the rooms
• Add an SQL constraint to make sure no two properties have the same name
• Add an api.constrains to make sure the construction_date is not in the future
