Question

I am getting the following error: view_page() takes exactly 2 arguments (1 given)

The code of view.py is:

from wiki.models import Page
from django.shortcuts import render_to_response

def view_page(request, page_name):
   try:
         page = Page.objects.get(pk=page_name)
   except PageDoesNotExist:
         return render_to_response("create.html", {"page_name":page_name})

the url given in url.py is :

url(r'^wiki/$', 'wiki.views.view_page'),

But when I am giving the url as given below and delete the above one then i am getting the error of page not found.

url(r'^wiki/(?P<page_name>[^/]+)/$','wiki.views.view_page'),

Answer 1

This is because the second parameter for the view_page() is passed in the url

example

url(r'^wiki/(?P<page_name>[^/]+)/$','wiki.views.view_page')

something.com/wiki/2   #here 2 is the second parameter which is like

def view_page(request, 2)

if u use this

url(r'^wiki/$', 'wiki.views.view_page'),

something.com/wiki/  #The second parameter is not passed to the function
