URL浏览和浏览DJANGO

Question

我不确定如何说出这个，但在这里。我有几个观点认为我的urls.py似乎根本看不到，我不知道为什么。我对django很陌生，并承认对它的一些工作有些困惑。

在我的模板，我有：

<ul> 
    <li><a href="/project/{{project.slug}}/tickets/create">Create Ticket</a></li> 
    <li><a href="/project/{{ project.slug }}/tickets/edit">Edit Ticket</a></li> 
    <li><a href="/project/{{ project.slug }}/tickets/delete">Delete Ticket</a></li> 
</ul> 

在我的urls.py：

(r'^ticket/(?P<ticket_id>\d+)$', views.editTicket), 
(r'^(?P<project_slug>[^\.^/]+)/tickets/create$', views.createTicket), 
(r'^(?P<project_slug>[^\.^/]+)/tickets/(?P<ticket_id>\d+)$', views.deleteTicket), 

在我views.py：

def createTicket(request, project_slug): 
    project = Project.objects.get(slug=project_slug) 
    form = None 
    if request.method == 'POST': 
     t = Ticket(created_by=request.user, assigned_to=request.user) 
     form = TicketCreateForm(request.POST, instance=t) 
     if form.is_valid(): 
      comment = Comment(user=request.user, body=request.POST.get("description", ""), subject="") 
      comment.save() 
      t.description = comment 
      form.save() 
      return HttpResponseRedirect("/project/ticket/%d" % t.pk) 
    else: 
     form = TicketCreateForm(instance=Ticket(project=project, assigned_to=request.user)) 
    payload = { 'project':project, 'form':form } 
    return render(request, 'project/ticket_add.html', payload) 

def editTicket(request, ticket_id): 
    ticket = Ticket.objects.get(pk=ticket_id) 
    if request.method == 'POST': 
     form = TicketCreateForm(request.POST, instance=ticket) 
     if form.is_valid(): 
      form.setComment(Comment(parent=ticket.description, user=request.user, body=request.POST.get("comment", " "))) 
      form.save() 
    form = TicketCreateForm(instance=ticket) 
    payload = { 'project':ticket.project, 'ticket':ticket, 'ticket_form':form } 
    return render(request, 'project/ticket.html', payload) 

def deleteTicket(request, ticket_id): 
    ticket = Ticket.objects.get(pk=ticket_id) 
    ticket.delete() 
    redirect_to = 'project/tickets.html' 
    return HttpResponseRedirect(redirect_to) 

def editTicket(request, ticket_id): 
    ticket = Ticket.objects.get(pk=ticket_id) 
    if request.method == 'POST': 
     form = TicketCreateForm(request.POST, instance=ticket) 
     if form.is_valid(): 
      form.setComment(Comment(parent=ticket.description, user=request.user, body=request.POST.get("comment", " "))) 
      form.save() 
    form = TicketCreateForm(instance=ticket) 
    payload = { 'project':ticket.project, 'ticket':ticket, 'ticket_form':form } 
    return render(request, 'project/ticket.html', payload) 

我在做什么错在这里？谁能帮忙？

有几个问题在这里，

首先，除非你已经修改了相关设置，最好是添加/到您的网址年代末以来，特别是要包括在你的URL正则表达式$，和django可能会重定向到您的地址添加最后一个斜杠。

其次，您的deleteTicket功能，以request和ticket_id为参数，而根据您的正则表达式需要3，project_slug丢失。

3rd，<a href="/project/{{ project.slug }}/tickets/delete">Delete Ticket</a>根本不符合(r'^(?P<project_slug>[^\.^/]+)/tickets/(?P<ticket_id>\d+)$', views.deleteTicket),，因为没有符号ticket_id。

4th（与匹配问题无关），您正在通过HTTP GET请求删除一个对象，这可能不是一个好主意（例如，它可能被缓存或搜索引擎可能会尝试点击它）。另外拨打Ticket.objects.get(pk=ticket_id)可能会引发异常，请尝试get_object_or_404(Ticket, pk=ticket_id)，这更有可能做到您想要的。它在from django.shortcuts import get_object_or_404。

如果这样做不成功，请尝试查看模板中显示的HTML源代码（使用替代值{{project.slug}}），以便进一步执行检查。

希望这可以帮助你。
