奇怪的錯誤，異常值：類型對象沒有屬性'DoesNoExist'

我有這段代碼。我不明白爲什麼它表明我似乎沒有已經存在的時候把DoesNotExist處理程序錯誤....並表明我這個錯誤：奇怪的錯誤，異常值：類型對象沒有屬性'DoesNoExist'

AttributeError at /hotel/edit/hotel-riodssdfsdf-google-facebook-351/

type object 'hotel' has no attribute 'DoesNoExist'

Request Method: GET Request URL: http::9000/hotel/edit/hotel-riodssdfsdf-google-facebook-351/ Django Version: 1.6.2 Exception Type: AttributeError Exception Value:

type object 'hotel' has no attribute 'DoesNoExist'

Exception Location: views.py in update, line 171

LINE 171是正確的....：除了酒店.DoesNoExist：

if 'member_id' not in request.session: 

    return HttpResponseRedirect('/login/') 

else: 

    if request.POST: 

     try: 

      hotelObject = hotel.objects.get(slug=slug) 

      form = UpdateHotelForm(request.POST, instance=hotelObject) 

      if form.is_valid(): 

       now = datetime.datetime.now() 
       name = form.cleaned_data['name'] 
       slug_name = slugify(name + ' ' + str(now.microsecond)) 

       hotels = hotel.objects.get(
        id=hotelObject.id, 
        publisher=request.session['member_id']) 

       hotels.name = name 

       hotels.slug = slug_name 

       hotels.save() 

       args = {} 

       args.update(csrf(request)) 

       args['form'] = form 
       args['message'] = False 
       args['name'] = hotelObject.name 

       return HttpResponseRedirect('/hotel/edit/' + slug_name) 

      else: 

       args = {} 

       args.update(csrf(request)) 

       args['form'] = form 
       args['message'] = True 
       args['name'] = hotelObject.name 

       return render_to_response('hotel/edit_hotel.html', args) 

     except hotel.DoesNoExist: 

      return HttpResponseRedirect('/hotel/') 
    else: 

     try: 

      hotelObject = hotel.objects.get(slug=slug) 

      form = UpdateHotelForm(request.POST, instance=hotelObject) 

      form = UpdateHotelForm(instance=hotelObject) 

      args = {} 

      args.update(csrf(request)) 

      args['form'] = form 
      args['name'] = hotelObject.name 

      return render_to_response('hotel/edit_hotel.html', args) 

     except hotel.DoesNoExist: 

      return HttpResponseRedirect('/hotel/')

其中'hotel.DoesNoExist'定義？ – mhlester

難道你不是指的DoesNotExist而不是DoesNoExist？ – kirbuchi

它與問題無關，但您應該在CamelCase中命名您的Django模型（即「酒店」而不是「酒店」）。 –

正確的hotel.DoesNotExist不hotel.DoesNoExiste一個

謝謝..我從來沒有檢查過這個咒語兩次。抱歉，因爲這個問題而煩惱。 – eddwinpaz

你拼錯DoesNotExist爲DoesNoExist。將其更改爲：

except hotel.DoesNotExist:
