View takes exactly 2 arguments (1 given)

In the main urls.py:

url(r'^request/(Req_.*)/someoperation/',include(someoperation.urls))

In someoperation.urls:

url(r'^query$', queryPage),

queryPage looks like:

def queryPage(request, request_id):
    #somestuff
    return HttpResponse('OK')

The URL getting opened is:

myhost:myport/request/Req_ABCXYZ/someoperation/query

But I get this error:

ec/2014 05:41:18] ERROR [django.request:215] Internal Server Error: /request/Req_ABCXYZ/someoperation/query
Traceback (most recent call last):
  File "/opt/xyz/build/lib/python2.7/site-packages/django/core/handlers/base.py", line 111, in get_response
    response = callback(request, *callback_args, **callback_kwargs)
TypeError: queryPage() takes exactly 2 arguments (1 given)

What could be going on? I'm sure Req_.* matches Req_ABCXYZ; so it should be getting passed on to the view queryPage.

Any clue?

Like the error message says, you're only passing one variable to the function, when it's expecting two. Assuming that request_id is required for your function to work you'll have to modify your urls.py so that it captures the request_id from the URL and passes it to the view.

This simple example should give you an idea how to go about it:

urls.py

urlpatterns = patterns('',
    url(r'^(?P<slug>[\w\-]+)/$', 'base.views.index'),
)

views.py

def index(request, slug=None):
    if slug is not None:
        return HttpResponse(slug)
    else:
        return HttpResponse("No slug provided")

It's basically a case of wrapping your regex in (?INSERT_REGEX_HERE) tag, so in your case it would be:

(?P<request_id>Req_.*)

Try this:

url(r'^request/(?P<request_id>Req_.*)/someoperation/',include(someoperation.urls))
