Having trouble catching variables from urls.py with views.py

I am trying to capture 2 slugs/variables from a url, pass them to a view and then use the view to pass them to a template.

The relevant line from my urls.py:

url(r'^docs/(?P<ver>)[-\w]+/(?P<name>)[-\w]+/$', views.sphinxdoc),

My views.py:

from django.shortcuts import render

def sphinxdoc(request, ver, name):
    context = {'ver': ver, 'name': name}
    return render(request, 'sphinx-documentation.html', context)

I am trying to change the src url of an <iframe> based on the ver and name values like so:

<iframe src="{% static 'docs/'|add:ver|add:'/'|add:name|add:'/_build/html/index.html' %}"></iframe>

When viewing in the browser, I get an error saying 'docs///_build/html/index.html' could not be found. It seems like the template variables 'ver' and 'name' never get set and are therefore rendered as empty strings. How would I allow for these variables to be set from the views.sphinxdoc function?

change urls.py like this:

url(r'^docs/(?P<ver>\w+)/(?P<name>\w+)/$', views.sphinxdoc),

Since the name slug could have "-"'s in it this won't quite work. Instead I used this:

url(r'^docs/(?P<ver>[-\w]+)/(?P<name>[-\w]+)/$, views.sphinxdoc),

I figured it out and thought I would post the solution here for anyone else that might stumble into this problem.

I am not sure why, but when pulling in ver and name as a functional parameter, its variable type was not being set as string. To solve this I just converted the variables to strings like so:

from django.shortcuts import render

def sphinxdoc(request, ver, name):
    ver = str(ver)
    name = str(name)
    return render(request, 'sphinx-documentation.html', {'ver': ver, 'name': name})

This fixed the issue.

Edit: Additionally, you can simplify by doing in-line string conversion...

def sphinxdoc(request, ver, name):
    return render(request, 'sphinx-documentation.html', {'ver': str(ver),
                                                         'name': str(name)})
