Django的第一个应用程序

Question

我的第一个django应用程序（它的名字是magghy）有一些问题。我正处于开发阶段。所以，我有： magghy/urls.py：

from django.conf.urls import * 
from magghy import views 

from . import views 

app_name = 'magghy' 

urlpatterns = [ 
    # esempio: /magghy/ 
    url(r'^$', views.index, name='index'), 
    #esempio: /magghy/5/ 
    url(r'^(?P<question_id>[0-9]+)/$', views.detail, name='detail'), 
    # ex: /magghy/5/results/ 
    url(r'^(?P<question_id>[0-9]+)/results/$', views.results, name='results'), 
    # ex: /magghy/5/vote/ 
    url(r'^(?P<question_id>[0-9]+)/vote/$', views.vote, name='vote'), 
] 

在magghy/views.py：

from __future__ import unicode_literals 

from django.shortcuts import get_object_or_404, render 
from django.http import HttpResponseRedirect, HttpResponse 
from .models import Choice, Question 
from django.template import loader 
from django.urls import reverse 



#visualizzare domande e argomento specifico - collegare con modulo magghy.urls 
def detail(request, question_id): 
    return HttpResponse("You're looking at question %s." % question_id) 

def results(request, question_id): 
    response = "You're looking at the results of question %s." 
    return HttpResponse(response % question_id) 

def vote(request, question_id): 
    return HttpResponse("You're voting on question %s." % question_id) 

#visualizzare pagina html secondo schema index.html oppure html 404 (eccezione) 
def index(request): 
    latest_question_list = Question.objects.order_by('-pub_date')[:5] 
    template = loader.get_template('magghy/index.html') 
    context = RequestContext (request, { 
     'latest_question_list': latest_question_list, 
    }) 
    return HttpResponse(template.render(context)) 

#visualizzare pagina 404  
def detail(request, question_id): 
    try: 
     question = Question.objects.get(pk=question_id) 
    except Question.DoesNotExist: 
     raise Http404("Question does not exist") 
    return render(request, 'polls/detail.html', {'question': question}) 

在mysite的/ urls.py：

from django.conf.urls import * 
from django.contrib import admin 
from magghy import views 

urlpatterns = [ 
    url(r'^magghy/', views.detail), 
    url(r'^admin/', include (admin.site.urls)), 
] 

页http://127.0.0.1:8000/admin/完美的作品！ 页http://127.0.0.1:8000/magghy/不起作用 页面http://127.0.0.1:8000/magghy/5不起作用

在这两种情况下，终端日志：

Internal Server Error: /magghy/ 
Traceback (most recent call last): 
    File "/Library/Python/2.7/site-packages/django/core/handlers/exception.py", line 41, in inner 
    response = get_response(request) 
    File "/Library/Python/2.7/site-packages/django/core/handlers/base.py", line 187, in _get_response 
    response = self.process_exception_by_middleware(e, request) 
    File "/Library/Python/2.7/site-packages/django/core/handlers/base.py", line 185, in _get_response 
    response = wrapped_callback(request, *callback_args, **callback_kwargs) 
TypeError: detail() takes exactly 2 arguments (1 given) 

请，你能帮帮我吗？非常感谢！

mysite的/ urls.py直接链接到详细视图，而不是包括该应用的URL。它应该是：

urlpatterns = [ 
    url(r'^magghy/', include('magghy.urls')), 
    url(r'^admin/', include (admin.site.urls)), 
]
