Django - 如何为 Polls 应用程序显示多个选项

如何解决Django - 如何为 Polls 应用程序显示多个选项

按照 Django polls 应用程序教程，我想知道是否不是为选择模型设置一个 Charfield，而是将每个响应/选择手动添加到数据库中；可以有选择吗？

例如：

class Poll(models.Model):
    text = models.CharField(max_length=255)
    pub_date = models.DateField()

def __str__(self):
    return self.text

class Choice(models.Model):
    question = models.ForeignKey(Poll,on_delete=models.CASCADE)
    choice_text = models.CharField(max_length=255)
    Votes = models.IntegerField(default=0)

    def __str__(self):
        return "{} - {}".format(self.question.text[:25],self.choice_text[:25])

您对每个投票都有标准选择，如下所示：

class Poll(models.Model):
   text = models.CharField(max_length=255)
   pub_date = models.DateField()

   def __str__(self):
      return self.text



class Choice(models.Model):
    VOTING_CHOICES = (
    ('Aye','Aye'),('Nay','Nay'),('Abstain','Abstain'),)
    question = models.ForeignKey(Poll,on_delete=models.CASCADE)
    choice_text = models.CharField(
                  max_length=7,choices=VOTING_CHOICES,default='Aye',)**
    Votes = models.IntegerField(default=0)

     def __str__(self):
        return "{} - {}".format(self.question.text[:25],self.choice_text[:25])


Poll Detail page
========


{{ poll }}
<form action="" method="post">
    {% csrf_token %}

    {% for choice in poll.choice_set.all %}
    {% for i,k in choice.VOTING_CHOICES %}

      <input type="radio"
          name="option"
          id="choice{{forloop.counter}}"
          value="{{ i }}"/>
      <label for="choice{{forloop.counter}}">{{ k }}</label>
     {% endfor %}
     {% endfor %}

    <input type="submit" value="Vote">

    </form>

views.py

def poll_detail(request,poll_id):

    #render poll detail page

    poll= get_object_or_404(Poll,id=poll_id)

    if request.method =="POST":
        print(request.POST)
     # Debug to see what data I am posting on form submission 

    context = {
        'poll':poll,}

    return render(request,'app/poll_detail.html',context)

有意义吗？每次我尝试实现这一点时，当我从表单 POST 或选项显示在元组中时，我要么得到一个空的字典响应（或者根本不呈现）。
