• The main model estate.property with relevant business fields (name, price, expected price, description, living area, garden, garage, etc.).
• Custom menus, actions, form and list views for estate.property.
• Field attributes like readonly, copy, required, and default values.
• Access rights through ir.model.access.csv for developers.
• Multiple record filtering using domain, search, and view buttons.
• Related models:
  • estate.property.type`: Many2one for property types.
  • estate.property.tag`: Many2many tags with selection UI.
  • estate.property.offer`: One2many offer list per property with inline editing
  • Links to existing models: res.partner (buyer), res.users (salesperson).
• Navigation enhancements through related fields and smart buttons.
