When I click on the send button, a wizard will be displayed.
I have a list of partners (partners--->[18, 3, 19, 17]).   I want them to be added automatically in the "Recipients" field of the wizard. And, the mail will be sent to all of them.

But, I got this error :

  email_values={'email_to': user.email})
AttributeError: 'int' object has no attribute 'email'

Any help please??

My code :

for user in partners:
            mail_template.send_mail(self.id, force_send=True,
            raise_exception=True,
            email_values={'email_to': user.email})
