NoReverseMatch /添加/ 4

反轉爲 'author_update' 與參數 '（）' 和關鍵字參數 '{' PK'：39， 'user_id'：>}'找不到。 1個圖案（多個）嘗試：[ '作者/（ΔP\ d +）/（ΔP\ d +）$']

嘗試此行return reverse('author_update', kwargs={'pk': self.pk, 'user_id': self.created_by})更改爲：

return reverse('author_update', args=(self.pk, self.created_by.pk))

或

return reverse('author_update', 
       kwargs={'pk': self.pk, 'user_id': self.created_by.pk})

這是我得到了什麼。 NoReverseMatch在關於 'author_update' 與參數 '（>，42）'/作者/添加/ 4 反向和關鍵字參數 '{}' 未找到。 1種模式（S）嘗試：[ '作者/（P \\ d +）/（P \\ d +）$'] – user2387135

@ user2387135兩個參數應該是數字，檢查更新 – ndpu

謝謝！這個偉大的工作回報反向（ 'author_update'， kwargs = { 'PK'：self.pk， 'USER_ID'：self.created_by.pk}） – user2387135
