通過Odoo中的代碼發送電子郵件時出錯

Question

我通過單擊模塊“ linh_warehoues”中的“發送電子郵件”按鈕創建了一個發送電子郵件的功能，但出現此錯誤：

關系“ mail_thread”不存在

我真的不明白這是什么意思。 我還檢查了“ mail_thread.py”中是否存在類“ mail_thread”。 希望大家能幫助我。 預先感謝您的幫助和建議。

這是我的代碼：

Answer 1

問題在這里：

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

該對象是您的，我的懷疑是，與account.invoice或sale.order不同，您的對象不繼承自mail.thread並且沒有評論歷史記錄。 但是通過使用：

'default_composition_mode': 'comment',

您在告訴向導不僅要發送郵件，還要將郵件作為注釋附加到對象的歷史記錄中。

解決方案將是為您的對象啟用評論歷史記錄，或引用要發布到的另一個對象。

Answer 2

這是您send_mail代碼的錯誤，請嘗試以下代碼：

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)
