pass kwargs for the view in reverse; django 1.5

Being a django starter, I have a little problem to deal with:

html code:

<li><a href="{% url 'dyn_display' category='first'%}">first</a></li>
<li><a href="{% url 'dyn_display' category='second'%}">second</a></li>
<li><a href="{% url 'dyn_display' category='third'%}">third</a></li>

urlconf.py

url(r'(?P<category>[a-z]+)$', 'display', name='dyn_display')

view.py

def courses_display(request, category):
    return render_to_response('display/basic.html', {category: 'in'}, context_instance=RequestContext(request))

and finally a part of basic.html, so you can get a thought of why i need that category variable

basic.html

<div class="accordion" id="accordion2">
    <div class="accordion-group">
        <div class="accordion-heading">
            <a class="accordion-toggle" data-toggle="collapse" data-parent="#accordion2" href="#collapseFirst">
                <strong>First</strong>
            </a>
        </div>
        <div id="collapseFirst" class="accordion-body collapse {{ first }}">
             <div class="accordion-inner">
                 ...
             </div>
         </div>
     </div>
     <div class="accordion-group">
         <div class="accordion-heading">
             <a class="accordion-toggle" data-toggle="collapse" data-parent="#accordion2" href="#collapseSecond">
                 <strong>Second</strong>
             </a>
         </div>
         <div id="collapseSecond" class="accordion-body collapse {{ second }}">
             <div class="accordion-inner">
                 ...
             </div>
         </div>
     </div>
     <div class="accordion-group">
         <div class="accordion-heading">
             <a class="accordion-toggle" data-toggle="collapse" data-parent="#accordion2" href="#collapseThird">
                 <strong>Third</strong>
             </a>
         </div>
         <div id="collapseThird" class="accordion-body collapse {{ third }}">
             <div class="accordion-inner">
                 ...
             </div>
         </div>
      </div>
  </div>

Since the whole page is done with bootstrap and Jquery, last parts of url

some/url/first

some/url/second

some/url/third

are kind of ugly, since the accordion element lets me collapse and open respective inner bodies without reloading the page. So the question is: is there a way to pass a kwarg in reverse, that's going to be used in a view, not to determine the url in reverse()?

the way I get url like some/url/ and, still passing kwarg from the first .html page to the view?

You could use this:

If this was your url:

url(r'(?P<category>[a-z]+)$', 'display', name='dyn_display')
reverse('dyn_display', kwargs={'category': 'first'})

To redirect you can use it like this in your view:

from django.http import HttpResponseRedirect
return HttpResponseRedirect(reverse('dyn_display', kwargs={'category': 'first'}))

If this was your url:

url(r'$', 'display', name='dyn_dysplay')
reverse('dyn_display')

To redirect you can use it like this in your view:

from django.http import HttpResponseRedirect
return HttpResponseRedirect(reverse('dyn_display'))

To have a view that could receive an optional value you would need 2 urls:

url(r'$', 'display', name='dyn_optional_display')    
url(r'(?P<category>[a-z]+)$', 'display', name='dyn_display')

And then your view:

def courses_display(request, category=None):
    ctx = {}
    if category:
        ctx.update({category: 'in'})
    return render_to_response('display/basic.html', ctx,    context_instance=RequestContext(request))
