URL瀏覽和瀏覽DJANGO

Question

我不確定如何說出這個，但在這裏。我有幾個觀點認爲我的urls.py似乎根本看不到，我不知道爲什麼。我對django很陌生，並承認對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) 

我在做什麼錯在這裏？誰能幫忙？

Answer 1

有幾個問題在這裏，

首先，除非你已經修改了相關設置，最好是添加/到您的網址年代末以來，特別是要包括在你的URL正則表達式$，和django可能會重定向到您的地址添加最後一個斜槓。

其次，您的deleteTicket功能，以request和ticket_id爲參數，而根據您的正則表達式需要3，project_slug丟失。

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),，因爲沒有符號ticket_id。

4th（與匹配問題無關），您正在通過HTTP GET請求刪除一個對象，這可能不是一個好主意（例如，它可能被緩存或搜索引擎可能會嘗試點擊它）。另外撥打Ticket.objects.get(pk=ticket_id)可能會引發異常，請嘗試get_object_or_404(Ticket, pk=ticket_id)，這更有可能做到您想要的。它在from django.shortcuts import get_object_or_404。

如果這樣做不成功，請嘗試查看模板中顯示的HTML源代碼（使用替代值{{project.slug}}），以便進一步執行檢查。

希望這可以幫助你。
