Error when sending email through code in Odoo

问题

I created a function to send email by clicking a button "send email" in module "linh_warehoues" and I have this error:

relation "mail_thread" does not exist

I really don't understand what it means. I also checked and the class "mail_thread" exists in "mail_thread.py". Hope everyone can help me. Thank you in advance for your help and advice.

Here is my code:

回答1:

The problem is here:

'default_model': 'linh.warehouse.receipt',

This object is yours, and my suspicion is that unlike account.invoice or sale.order your object does not inherit from mail.thread and does not have a comment history. However by using:

'default_composition_mode': 'comment',

You are telling the wizard to not only send a mail, but also attach the mail as a comment to the history of your object.

The solution will be either to enable comment history for your object, or to reference another object to post to.

回答2:

This is error of the your send_mail code try this code:

class MailComposeMessage(models.Model):
    _inherit = 'mail.compose.message'

    @api.multi
    def send_mail(self, auto_commit=False):
        if self._context.get('default_model') == ''linh.mail' and self._context.get('default_res_id'):
        return super(MailComposeMessage, self.with_context(mail_post_autofollow=True)).send_mail(auto_commit=auto_commit)
