Django url参数和反向URL [英] Django url parameter and reverse URL

问题描述

我有一个看起来像这样的视图:

I have a view that looks like this:

def selectCity(request, the_city):
    request.session["ciudad"] = the_city
    city = request.session["ciudad"]
    return HttpResponse('Ciudad has been set' + ": " + city)

还有一个看起来像这样的URL:

And a URL that looks like this:

url(r'^set/$', views.selectCity, {'the_city': 'gye'}, name='ciudad'),

现在，当我访问/set/时，我会从URL {'the_city':'gye'}的dict值中获得适当的响应，其中包含会话变量集

Now when I visit /set/ I get the appropriate response with the session variable set from the value on the dict in the url {'the_city': 'gye'}

现在，我想做的就是修改程序，以便可以从其他模板(index.html)调用"ciudad" URL并设置适当的会话变量.因此，我会使用反向URL匹配和一个类似这样的附加参数来调用它:

Now, what I would like to do is modify my program so that I can call the 'ciudad' url from a different template (index.html) and set the appropriate session variable. So I would call it using reverse URL matching with an additional argument doing something like this:

  <div class="modal-body">
      <a tabindex="-1" href="{% url ciudad 'the_city':'uio' %}">Quito</a>
      <br/>
      <a tabindex="-1" href="{% url ciudad 'the_city':'gye' %}">Guayaquil</a>
  </div>

我试图以各种方式修改url和视图以及反向url调用，以尝试使其正常工作，但是，我似乎无法弄清楚.我真的很感谢一些指针.

I have tried to modify the url and the views and the reverse url call in various ways to try to get this to work but, I can't seem to figure it out. I would really appreciate some pointers.

推荐答案

如果您的URL(在 urls.py 中)具有任何捕获组，则可以在url标记中传递相关的参数.

You can pass the relevant arguments in url tag, if your url (in urls.py) has any capturing group.

url(r'^set/(?P<the_city>\w+)/$', views.selectCity, {'the_city': 'gye'}, name='ciudad'),

然后进入模板:

<a tabindex="-1" href="{% url ciudad the_city='gye' %}">Guayaquil</a>
