Django的崗匹配查詢不存在

雖然增加後到我的博客，我收到以下錯誤Post matching query does not exist.我最近改變了所有的蛞蝓領域，但是這沒有關係，我相信Django的崗匹配查詢不存在

URL.py

url(r'^$', views.PostListView.as_view(),name='home'), 
url(r'^(?P<slug>[\w-]+)/$', views.detail, name='detail'), 
url(r'^editPost/(?P<slug>[\w-]+)/$', views.edit_post, name='edit_post'), 
url(r'^deletePost/(?P<slug>[\w-]+)/$', views.delete_post, name='delete_post'), 
url(r'^addPost/$', views.add_post, name='add_post'),

views.py

def detail(request, slug): 
    post = Post.objects.get(slug=slug) 
    comments=post.comment_set.all() 
    forms=CommentForm 
    if request.method == 'POST': 
     form=CommentForm(request.POST) 
     if form.is_valid(): 
      comment = form.save(commit=False) 
      comment.title = post 
      print comment 
      comment.save() 
     else: 
      print form.errors 
    else: 
     form = PostForm() 

    return render(request, "blog_detail.html", {'forms':forms,'post': post,'comments':comments}) 

def add_post(request): 
    forms = PostForm 
    if request.method == 'POST': 
     form = PostForm(request.POST) 
     print form 
     if form.is_valid(): 
      uncommit = form.save(commit=False) 
      title= form.cleaned_data['title'] 
      description=form.cleaned_data['description'] 
      form.save() 
      return redirect("home") 
     else: 
      print form.errors 
    else: 
     form = PostForm() 
    return render(request, "add_post.html", {'forms': forms})

當我點擊add選項時，會生成以下錯誤。模板add_post

add_post.html

{% block blog_post %} 
    <form method="POST" action="{% url 'add_post' %}">{% csrf_token %} 
     {{ forms|crispy }} 
     <input type="submit"> 
    </form> 


{% endblock %}

我真的不知道什麼是錯誤的，因爲查詢不存在...任何幫助表示讚賞...預先感謝

檢查是否hace Post對象與給定的slu 012 – Gocht

你可以用你的stacktrace編輯問題嗎？另外，在你的django shell中，你可以執行'Post.objects.get（slug = slug）'並且成功獲得一個Post對象嗎？ – karthikr

當Django搜索URL模式時，它會選擇匹配的第一個模式。目前，/addPost/正在由詳細視圖處理，由於您沒有addPost的帖子，因此會引發錯誤。

您可以通過將detail URL模式移動到列表底部來解決此問題。

url(r'^$', views.PostListView.as_view(),name='home'), 
url(r'^addPost/$', views.add_post, name='add_post'), 
url(r'^editPost/(?P<slug>[\w-]+)/$', views.edit_post, name='edit_post'), 
url(r'^deletePost/(?P<slug>[\w-]+)/$', views.delete_post, name='delete_post'), 
url(r'^(?P<slug>[\w-]+)/$', views.detail, name='detail'),
