You can use this view to have a possibility to use ?paginate_by=x on your generic lists.
Example usage in urls.py:
url('^list/', object_list_with_paginate_by,
{'queryset': Invoice.objects.all(), 'template_name': 'invoices/list.html', 'paginate_by': 10},
'invoices.list')
10 is the default objects count per page.
For the first time parameter paginate_by is set in URL, we have to get it straight from there. If the parameter is set, then also set the cookie for later requests without the parameter If the parameter is not set, then we try the cookie or default value
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 | def object_list_with_paginate_by(request, **kwargs):
is_valid_paginate_by_parameter = True
try:
paginate_by = int(request.GET.get('paginate_by', 0))
except ValueError:
paginate_by = 0
if not paginate_by: #don't make it into else!
is_valid_paginate_by_parameter = False
try:
paginate_by = int(request.COOKIES.get('paginate_by', 0))
except ValueError:
paginate_by = 0
if paginate_by: #don't make it into else!
kwargs['paginate_by'] = paginate_by
response = object_list(request, **kwargs)
if is_valid_paginate_by_parameter:
response.set_cookie('paginate_by', paginate_by)
return response
