Odoo: how in *.js file get record from db, then change it and re-write?

I added new settings for user by inheriting “res.users” model:

calendar_scale_type = fields.Selection([
        ('day', 'Day'),
        ('week', 'Week'),
        ('month', 'Month'),
        ('year', 'Year')],
        'Type of calendar scaling', default='week')

in calendar view i want to read this field and set scale_type when opening this form here in calendar_model.js file i want to read this setting from current user

and also rewrite current user setting if he chooses diferent type of scale here

how can i do this? i tried to use rpc, but i do something wrong and it didn`t work.

Answer

You can override the session_info and add calendar_scale_type to use it later in the calendar model (You will need to override the setScale function).

Example:

1. Add calendar_scale_type to the session info:

   class Http(models.AbstractModel):
       _inherit = 'ir.http'
   
       def session_info(self):
           session_info = super(Http, self).session_info()
           session_info['calendar_scale_type'] = self.env.user.calendar_scale_type
           return session_info
   

2. Override setScale function:

   /* @odoo-module */
   
   import CalendarModel from '@calendar/js/calendar_model';
   import { session } from "@web/session";
   
   CalendarModel.include({
   
       setScale: function (scale) {
           if (!_.contains(this.scales, scale)) {
               scale = session.calendar_scale_type;
           }
           this._super(scale);
       },
   
   });
