#18421 closed Bug (invalid)
Pagination documentation contains error when no GET request provided

Description
The current Pagination documentation contains:
page = request.GET.get('page')
This should instead be:
page = request.GET.get('page', 1)
or else, it fails when no GET parameter is provided, which is unfortunate.
I'll attach a patch momentarily.

Patch applies cleanly against master and looks good to me.

If 'page' is not provided in the request, the page variable will be None. Then paginator.page will raise PageNotAnInteger which will lead to the paginator.page(1) code path. Same scenario if page is set to anything other than a integer.

I'm probably about to put my foot square in my mouth, but claudep, when None is passed to Paginator.page, it throws a TypeError, not a PageNotAnInteger error:
In [1]: from django.core.paginator import Paginator In [2]: Paginator([], 25).page(None) --------------------------------------------------------------------------- TypeError Traceback (most recent call last) /var/www/court-listener/alert/<ipython-input-8-d36a5c4802f6> in <module>() ----> 1 contacts = paginator.page(None) /usr/lib/python2.7/dist-packages/django/core/paginator.pyc in page(self, number) 35 def page(self, number): 36 "Returns a Page object for the given 1-based page number." ---> 37 number = self.validate_number(number) 38 bottom = (number - 1) * self.per_page 39 top = bottom + self.per_page /usr/lib/python2.7/dist-packages/django/core/paginator.pyc in validate_number(self, number) 21 "Validates the given 1-based page number." 22 try: ---> 23 number = int(number) 24 except ValueError: 25 raise PageNotAnInteger('That page number is not an integer') TypeError: int() argument must be a string or a number, not 'NoneType'
So is it possible that the bug is actually in the Paginator code, that it should be catching this TypeError and throwing a PageNotAnInteger error instead of a TypeError?

Scratch that. I just dug into the pagination code...this is already fixed in 1.4. Just broken in 1.3, apparently.
Patch to fix the above issue.
