TemplateDoesNotExist at/polls/1/

我得到了一个错误， TemplateDoesNotExist在/ polls/1/ templates/polls/detail.html。我想显示detail.html。TemplateDoesNotExist at/polls/1/

回溯是

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

    19.  raise TemplateDoesNotExist(template_name, chain=chain) 

Exception Type: TemplateDoesNotExist at /polls/1/ 
Exception Value: templates/polls/detail.html

我forms.py就像是单选按钮的

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()

设置是写在detail.html，像

<!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, 
    })

我想装模板的地方，这是detail.html

return render(request,'templates/polls/detail.html',{ 
     'form':form, 
     'question': obj, 
    })

，所以我不明白为什么不显示我detail.html可以here.How解决这一问题？

您正在告诉Django使用templates/polls/detail.html。这意味着Django会寻找polls/templates/templates/polls/detail.html，这可能不是你想要的。

你还没有说你的模板在哪里，但我假设它在polls/templates/polls/detail.html。在这种情况下，你应该改变视图：

return render(request,'polls/detail.html', { 
    'form':form, 
    'question': obj, 
})

THX，我的网站工作的正确！但我不明白为什么改变“模板/调查/ detail.html”到“民意测验/ detail.html”可以修复错误。为什么？ – mikimiki

Django在你的'polls/templates /'文件夹中搜索模板。当你使用'templates/polls/detail.html'时，Django会查找不存在的'polls/templates/templates/polls/detail.html'。你不在任何其他视图中包含'templates'，所以你不应该为这个。 – Alasdair

想象一下，您必须在您的'polls/templates /'中搜索'templates/polls/detail.html'，您的'polls/templates'中没有任何名为'templates'的文件夹，对吗？您不必指定'templates'，因为django知道，但是您必须指定'polls'作为名称空间，这样django就知道这些模板是用于'polls'的。 – ShadowXsc
