如何在Django視圖中使用空用戶ID進行保存？

我有一個Django視圖，應該保存包含三個字段集的CalendarEvent（模型實例），包括當前用戶的配置文件對象。該觀點得到@login_required保護，我登錄的超級用戶，然後叫得到該錯誤的觀點：在回溯如何在Django視圖中使用空用戶ID進行保存？

/Users/jonathan/pim/../pim/pim_calendar/views.py in save_calendar 
      date_padding = '' 
     regexp = weekday + ' ' + month + ' ' + date_padding + date + \ 
      ' ..:..:.. ... ' + year 
     event = pim_calendar.models.CalendarEvent() 
     event.when = regexp 
     event.description = description 
     event.user = request.user.get_profile() 
     event.save()

。（request.user應該是我登錄的超級用戶。）

我得到的錯誤是：

如果我添加的event.save（）調用之前，

 print repr(event.user)

的控制檯顯示「」「<用戶配置：USERPROFILE對象> 」「」上IntegrityError在崩潰之前。

有什麼建議嗎？

從錯誤消息，它看起來像代替：

event.user = request.user.get_profile()

你應該調用此：

event.userprofile = request.user.get_profile()

除了什麼@jkbr說，你可能要考慮不拯救CalendarEvent對象中的UserProfile引用。

# Save event 
event = pim_calendar.models.CalendarEvent() 
event.user = request.user 
event.user.save() 

# Access the profile 
event = CalendarEvent.objects.get(...) 
the_userprofile = event.user.get_profile()

：相反，只保存與CalendarEvent相關聯的用戶，然後通過訪問用戶配置
