“得到一个意想不到的关键字参数”ticket_id“” [英] "got an unexpected keyword argument 'ticket_id'"

问题描述

我正在开发一个项目管理应用程序。一个项目可以拥有与项目相关的票据，并在项目下面的模板中以及项目的票据。

但是，我收到错误下面的代码，我无法弄清楚它的意思和解决方法：

 异常值：show_ticket（）得到一个意想不到的关键字参数'ticket_id'
异常位置：/Library/Python/2.7/site-packages/Django-1.4.5-py2.7.egg/django/contrib/auth/decorators.py在_wrapped_view中，第20行
  

可能有什么问题？

项目模板

  {％为门票％} 
< span> ; {{ticket}}< / span> 
< a href ={％url show_ticket project.id ticket.id％}>显示票证< / a>< br /> 
 {％endfor％} 
  

urls.py： / p>

  url（r'^ project /（？P< project_id> \d +）/ ticket /（？P< ticket_id& \\ d +）/ $'，'project_app.views.show_ticket'，name =show_ticket），
  

视图：

  @login_required 
 def show_ticket（request，project_id）：
 ticket = get_object_or_404（Ticket，pk = ticket_id）
 
 return render（request，'projects / show_ticket.html'，{ticket：ticket}）
  

解决方案

您的 show_ticket view只接受一个变量 - 项目编号。您在该视图中使用两个变量（ project.id 和 ticket.id 。

您的视图网址已设置为接受 ticket_id ，因此您只需要更改视图即可接受 ticket_id 还有：

  def show_ticket（request，project_id，ticket_id）：
 .... 
  

I'm working on a project management app. A project can have tickets, which are tied to the project and in the template below a project is rendered, as well as the project's tickets.

However, I get an error with the code below and I can't figure out what it means and how to solve it:

Exception Value:    show_ticket() got an unexpected keyword argument 'ticket_id'
Exception Location: /Library/Python/2.7/site-packages/Django-1.4.5-py2.7.egg/django/contrib/auth/decorators.py in _wrapped_view, line 20

What can be wrong?

project template:

{% for ticket in tickets %}
    <span>{{ ticket }}</span>
    <a href="{% url show_ticket project.id ticket.id %}">Show ticket</a><br/>
{% endfor %}

urls.py:

url(r'^project/(?P<project_id>\d+)/ticket/(?P<ticket_id>\d+)/$', 'project_app.views.show_ticket', name="show_ticket"),

view:

@login_required
def show_ticket(request, project_id):
    ticket = get_object_or_404(Ticket, pk = ticket_id)

    return render(request, 'projects/show_ticket.html', {"ticket" : ticket})

解决方案

Your show_ticket view only accepts one variable - the project id. You are calling the reverse on that view with two variables - project.id and ticket.id.

Your URL for the view is already setup to accept the ticket_id, so you just need to change your view to accept the ticket_id as well:

def show_ticket(request, project_id, ticket_id):
    ....
