您为每个问题使用了单独的表单，但浏览器只接受一个表单来发送给服务器，您必须使用django Formsets来解决此类问题。
<强>更新
此通知表示您在每个表单上只放置了一个输入很重要，您可以通过一些更改并且不使用 Django Formsets 来执行此操作：
我认为你的models.py类似于：
from django.db import models
class Question(models.Model):
body = models.CharField(max_length=200)
answer = models.CharField(max_length=200)
class Quiz(models.Model):
questions = models.ManyToManyField(Question)
您可以在forms.py中创建一个表单类来处理它：
from django import forms
from models import Quiz, Question
class QuizForm(forms.ModelForm):
class Meta:
model = Quiz
fields = '__all__'
questions = forms.ModelMultipleChoiceField(queryset=Question.objects.all(), widget=forms.CheckboxSelectMultiple)
您的views.py文件：
from django.shortcuts import render
from forms import QuizForm
def show(request):
return render(request, 'qtemplate.html', {'form': QuizForm()})
并在模板上：
<form method="post">
{{ form }}
</form>

不确定这是否是一个好的解决方案，但您可以尝试将“提交”输入标记移动到您的表单中：）
<html>
<body>
{% for question in latest_question_list %}
<h1>{{ question.question_text }}</h1>
{% if error_message %}
<p><strong>{{ error_message }}</strong>
</p>
{% endif %}
<form id="qform" action="{% url 'polls:vote' question.id %}" method="post">{% csrf_token %} {% for choice in question.choice_set.all %}
<input type="radio" name="{{ question.id }}" id=”choice{{ forloop.counter }} " value="{{ choice.id }}” />
<label for="choice{{ forloop.counter }}">{{ choice.choice_text }}</label>
<br/>{% endfor %}
</form>
<input form="qform" type="submit" value="Vote" />
{% endfor %}
</body>
</html>
或者你可以尝试使用Django-restframework +一些javascript框架（例如react）来实现这个功能
