How to create custom object in ODOO?

Question

Are there any way to create some new model after onchange triggered?

For example, I want to create my custom report object after the state of quotation is changed to sale order.

Answer 1

I solved that by trying to override action_confirm method of sale.order and it's worked!

class sale_order(models.Model) :
     _inherit = 'sale.order'
     job_container = fields.One2many('job.container','order')

     @api.multi
     def action_confirm(self):
            super(sale_order, self).action_confirm()
            self.env['job.container'].create({
                'order': self.id
            })

You can create a new instance of a model with the following code inside sales.order inside a method with the decorator @api.onchange('state'):

   report_model = self.env['my.custom.report.object']
   new_report_object = report_model.create({
         'report_message': 'Quotation changed state to Sales Order'
   })
