Adding a stat button to a form view

Odoo uses a stat button to relate two different objects visually on the form view. It is used to show some basic KPIs for related records. It is also used to redirect and open another view. In this recipe, we will add a stat button to the form view of a room. This stat button will display the count of room records and on clicking it, we will be redirected to the list of Kanban views.

Getting started

For this recipe, we will be using the my_hostel module from the previous recipe.

How to do it...

Follow these steps to add a stat button to the hostel’s form view:

1. Add the rooms_count compute field to the hostel.hostel model. This field will count the number of active rooms in the hostel:

   rooms_count = fields.Integer(compute="_compute_rooms_count")
   def _compute_rooms_count(self):
           room_obj = self.env['hostel.room']
           ...
