是否有可能將表單值存儲在django的下拉列表中

Question

我正在使用django提出問題應用程序，我允許用戶向網站添加問題，併爲每個問題定義了幾個可選答案提出問題的用戶。我想在下拉框中顯示可選答案。但我一直從我的模型得到一個錯誤，說選項一沒有定義。

選擇模式

class Choice(models.Model): 
    question = models.ForeignKey(Question, on_delete=models.CASCADE) 

    CHOICES = (
     (option_one,option_one), 
     (option_two,option_two), 

    ) 
    user_choice = models.CharField(
     max_length=200, 
     choices=CHOICES, 
     default=Yes, 
    ) 

    votes = models.IntegerField(default=0) 

    def __str__(self): 
     return self.user_choice 

視圖

def create_poll(request): 

    if request.method == 'POST': 
     form = CreatePollForm(request.POST) 
     if form.is_valid(): 
      question = form.cleaned_data['question'] 
      option_one = form.cleaned_data['option_one'] 
      option_two = form.cleaned_data['option_two'] 
      print option_one 
      q = Question.objects.create(question_text=question) 
      o = Choice.objects.create(question=q, option_one=option_one,option_two=option_two) 
      q.save() 
      o.save 

      form = CreatePollForm() 
      return render(request, 'polls/createPolls_form.html', {'form':form}) 

    form = CreatePollForm() 
    return render(request,'polls/createPolls_form.html',{'form':form}) 

forms.py

class CreatePollForm(forms.Form): 
     question = forms.CharField(max_length=100) 
     option_one = forms.CharField(max_length=100) 
     option_two = forms.CharField(max_length=100) 

Answer 1

你爲什麼不嘗試刪除默認的選擇，然後嘗試相同：

class Choice(models.Model): 
    question = models.ForeignKey(Question, on_delete=models.CASCADE) 

    user_choice = models.CharField(
     max_length=200, 
     default=Yes, 
    ) 

    votes = models.IntegerField(default=0) 

    def __str__(self): 
     return self.user_choice 

Answer 2

您正在使用option_one作爲變量，但未定義。你可以像'option_one'那樣將它用作字符串，或者可以像之前那樣將其定義爲option_one ='你想要定義的任何內容.....'
