Hello all,

In the file odoo-8.0-20151203/openerp/addons/point_of_sale/static/src/js/models.js, there is this code :

module.PosModel = Backbone.Model.extend({
models: [
        {
            model:  'res.users',
            fields: ['name','company_id'],
            ids:    function(self){ return [self.session.uid]; },
            loaded: function(self,users){ self.user = users[0]; },
        },{ 
            model:  'res.company',
            fields: [ 'currency_id', 'email', 'website', 'company_registry', 'vat', 'name', 'phone', 'partner_id' , 'country_id', 'tax_calculation_rounding_method'],
            ids:    function(self){ return [self.user.company_id[0]] },
            loaded: function(self,companies){ self.company = companies[0]; },
        },{
            model:  'decimal.precision',
            fields: ['name','digits'],
            loaded: function(self,dps){
                self.dp  = {};
                for (var i = 0; i < dps.length; i++) {
                    self.dp[dps[i].name] = dps[i].digits;
                }
            },
..............................................

I only want to modify ONE model (res.company) in my own module. Is it possible?

Or do I have to override ALL models even if I want to modify only one of them?

Thanks to help

UPDATE #1

With this code, I think that I override ALL the original models with only this new one. So, it doesn't work.

openerp.canada_rounding = function (instance) {
        var module=instance.point_of_sale
        var round_pr = instance.web.round_precision
        module.PosModel = module.PosModel.extend({
            models: [
                {
                    model:  'res.company',
                    fields: [ 'currency_id', 'email', 'website', 'company_registry', 'vat', 'name', 'phone', 'partner_id' , 'country_id', 'tax_calculation_rounding_method'],
                    ids:    function(self){ return [self.user.company_id[0]] },
                    loaded: function(self,companies){ self.company = companies[0]; },
                }
            ]
        });
}
