mail.thread 模型中添加计算字段

from odoo import models, fields, api


class MailThread(models.AbstractModel):
    _inherit = 'mail.thread'

    attachment_ids = fields.Many2many(comodel_name='ir.attachment', compute='_compute_attachment_ids')

    def _compute_attachment_ids(self):
        for rec in self:
            rec.attachment_ids = self.env['ir.attachment'].search(
                [('res_id', 'in', rec.ids), ('res_model', '=', self._name)])
