Hi everyone,

I’m stopped on pagination on the wonderful tutorial : http://pylonsbook.com/en/1.1/starting-the-simplesite-tutorial.html#using-pagination

I try to made the tutorial and adapt it when I can. The first problem I had is link to routes.url_for seems to be depreced and return me lot of mapper problems. I changed all my h.url_for by url… but it seems to be used to in import webhelpers.paginate as paginate

if someone have an idea…

Thanks

After reading : http://pylonshq.com/docs/en/1.0/thirdparty/webhelpers/paginate/

I had in my controller ‘page’ action=‘list’:
mapper = Mapper()
mapper.connect(’/page/list’)

Exemple :
def list(self):
mapper = Mapper()
mapper.connect(’/page/list’)

records = model.meta.Session.query(model.Page)
c.paginator = paginate.Page(
records,
page=int(request.params.get(‘page’, 1)),
items_per_page = 5,
)
return render(’/derived/page/list.html’)

It’s work, but I’m sure that there is a proper way, no ?

Perhaps with herit webhelpers.pagination and change all reference to url_for by pylons.url ?
