I'm trying to use the django pagination module including in the standard distribution version 1.3.
When attempting to load a page that is currently controlled by pagination, if I do not include ?page= on the uri, it throws a TypeError. I've never had this situation arise before, and do not see any reason for it occurring.
Here's my current view:
paginator = Paginator(mails_list, 25) # Shows 25 mails per page
page = request.GET.get('page')
try:
mails = paginator.page(page)
except PageNotAnInteger:
# If page is not an integer, deliver the first page.
mails = paginator.page(1)
except EmptyPage:
# If page is out of range (e.g. 9999), deliver last page of results
mails = paginator.page(paginator.num_pages)
TypeError:
int() argument must be a string or a number, not 'NoneType'
The error is being presented from line 3 of the above code:
mails = paginator.page(page)
Anyone witnessed this error before and/or know how to correct it?
Try changing this line:
page = request.GET.get('page')
To this:
page = request.GET.get('page', '1')
The problem is you're getting a parameter that doesn't exist. Indexing using []
would result in a KeyError
, but the get
method returns None
if it doesn't exist. The paginator is calling int(None)
, which fails.
The second parameter to the get
method is a default to return if the key doesn't exist rather than None
. I passed '1'
which int
should not fail on.
