Thank you very much for your effort to reply. I appreciated it.

Hii,

In Odoo 10 , def copy() and def write() are not designed to return an action (like opening a wizard or form view), because:

• They're data model methods , not action methods.
• They're typically called invisibly from backend logic or buttons , and the framework does not expect a return value from them.

So: Returning an action from write() or copy() is not directly possible.

BUT... There are workarounds depending on whyYou want to return an action:

Define a button method in your model

from odoo import models, api

class  MyModel (models.Model):
    _name = 'my.model'

    @api.multi 
    def  copy_and_open_wizard ( self ):
         # Step 1: Duplicate the record
        new_record = self.copy()

        # Step 2: Return a wizard action 
        return {
             'name' : 'Open Wizard' ,
             'type' : 'ir.actions.act_window' ,
             'res_model' : 'my.wizard.model' ,
             'view_mode' : 'form' ,
             'view_type' : 'form' ,
             'target' : 'new' ,
             'context' : {
                 'default_related_id' : new_record. id   # pre-fill field in wizard
            }
        }

Add the button in your XML form view

<button  name = "copy_and_open_wizard" 
        type = "object" 
        string = "Copy & Open Wizard" 
        class = "btn-primary" />

Define a simple wizard model (optional)

from odoo import models, fields

class  MyWizard (models.TransientModel):
    _name = 'my.wizard.model'

    related_id = fields.Many2one( 'my.model' , string= 'Related Record' )
    notes = fields.Text( 'Notes' )

i hope it is usefull
