This question has been flagged

I have receiving this odoo error when I try to duplicate a set of record. I have inherited ['mail.thread', 'ir.needaction_mixin'] in the current class. I didn't found any solution online or myself or from odoo. Still stuck here around for 2 days.

Anybody have any idea on this ? Currently I'm using Odoo 10.

Thanks & Regards in advance.

Try:

class Followers(models.Model): _inherit = 'mail.followers' @api.model def create(self, vals): if 'res_model' in vals and 'res_id' in vals and 'partner_id' in vals: dups = self.env['mail.followers'].search([('res_model', '=',vals.get('res_model')), ('res_id', '=', vals.get('res_id')), ('partner_id', '=', vals.get('partner_id'))]) if len(dups): for p in dups: p.unlink() return super(Followers, self).create(vals)

Can I add this to my code in an automated action to try and make it work?

Finally find the solution by myself. By adding the code below it is resolved

@api.model
def create(self, vals):
    res = super(ClassName, self).create(vals)
    subtype_ids = self.env['mail.message.subtype'].search(
        [('res_model', '=', 'class.name')]).ids
    res.message_subscribe(
        partner_ids=[res.name_id.partner_id.id],
        subtype_ids=subtype_ids)
    # other logic
    return res

create a file.py in your module, then inherite the mail.followers models
