I have created a Wizard with steps. Each Wizard contain a button "Next" to go to next wizard.

I want to create another button to return to the previous Wizard. I have try to make anothe function to call the previous

wizard, But the problem is i can't call the previous wizard because there is a required fileds. This my function which call the preivous wizard :

@api.multi
def call_previous(self):
   

    return {
        'name': 'Choix de méthode de vente',
        'type': 'ir.actions.act_window',
        'view_type': 'form',
        'view_mode': 'form',
        'res_model': 'affichage2.vente1',
        'view_id': self.env.ref("affichage2.confirm_wizard_form3").id,
        'context': {'current_id': self.id},
        # 'target': 'new',
        'nodestroy': True,
    }
