Question

我通过看django教程创建了一个网站。 https://docs.djangoproject.com/en/1.11/intro/ 我收到了一个错误 / polls / 1 /的AttributeError ＆＃39;方法＆＃39;对象没有属性＆＃39; inner_html＆＃39; 。 Traceback说

Traceback:

File "/Users/XXX/django/django/core/handlers/exception.py" in inner
  35.             response = get_response(request)

File "/Users/XXX/django/django/core/handlers/base.py" in _get_response
  130.                 response = self.process_exception_by_middleware(e, request)

File "/Users/XXX/django/django/core/handlers/base.py" in _get_response
  128.                 response = wrapped_callback(request, *callback_args, **callback_kwargs)

File "/Users/XXX/djangostudy/polls/views.py" in detail
  40.         form = VoteForm(question=obj)

File "/Users/XXX/djangostudy/polls/forms.py" in __init__
  21.         self.fields['choice'].widget.render.inner_html = '{choice_value}{sub_widgets}<br>'

Exception Type: AttributeError at /polls/1/
Exception Value: 'method' object has no attribute 'inner_html'

我的forms.py就像

from django import forms

class MyForm(forms.Form):
    text = forms.CharField(max_length=100,required=False,label='テキスト')

class VoteForm(forms.Form):
    choice = forms.ModelChoiceField(
        queryset=None,
        label='選択',
        widget=forms.RadioSelect,
        empty_label=None,
        error_messages={
            'required':"You didn't select a choice.",
            'invalid_choice':"invalid choice.",
        },
    )

    def __init__(self,question,*args,**kwargs):
        super().__init__(*args,**kwargs)
        self.fields['choice'].queryset = question.choice_set.all()
        self.fields['choice'].widget.render.inner_html = '{choice_value}{sub_widgets}<br>'

单选按钮的设置写在detail.html中，如

<!DOCTYPE html>
<h1>{{ question.question_text }}</h1>
{% if error_message %}<p><strong>{{ error_message }}</strong></p>{% endif %}

<form action="{% url 'poll_vote' question.id %}" method="post">
<!--<form action="" method="post">-->
    {% csrf_token %}
    {% for choice in question.choice_set.all %}
    <input type="radio" name="choice" id="choice{{ forloop.counter }}" value="{{ choice.id }}" />
    <label for="choice{{ forloop.counter }}">{{ choice.choice_text }}</label><br />
    {% endfor %}
    <!--{{ form }}-->
    <input type="submit" value="Vote" />
</form>
</html>

views.py是

from django.shortcuts import render
from django.utils.html import mark_safe
from .models import Question
from django.http import HttpResponse
from django.shortcuts import Http404
from django.shortcuts import get_object_or_404,redirect
from .models import Choice
from django.views.generic import TemplateView
from django.views.generic import DetailView
from django.views.generic import ListView
from .forms import MyForm
from .forms import VoteForm


# Create your views here.
def index(request):
    return render(request,'polls/index.html',{
        'questions': Question.objects.all(),
    })

def detail(request,pk):
    obj = get_object_or_404(Question,pk=pk)
    if request.method == "POST":
        form = VoteForm(question=obj,data=request.POST)
        if form.is_valid():
            return redirect('polls:results',pk)
    else:
        form = VoteForm(question=obj)
    return render(request,'templates/polls/detail.html',{
        'form':form,
        'question': obj,
    })

def vote(request,pk):
    pass

def results(request,pk):
    obj = get_object_or_404(Question,pk=pk)
    return render(request,'polls/results.html',{
        'question':obj,
    })

def form_test(request):
    if request.method == "POST":
        #request.POST???
        form = MyForm(data=request.POST)
        if form.is_valid():
            pass
    else:
        form = MyForm()
    return render(request,'polls/form.html',{
        'form':form,
    })

我不知道如何修复它。我无法理解为什么会发生这种错误。我应该怎么做才能解决这个问题？教程有inner_html，所以我认为有必要做一些必要的事情。但是，它没用吗？

我想要显示页面在这一部分 self.fields [＆＃39; choice＆＃39;]。widget.render.inner_html =＆＃39; {choice_value} {sub_widgets}
＆＃39;

我想让这个页面成为单选按钮页面。

＆＃39;方法＆＃39;对象没有属性＆＃39; inner_html＆＃39;
