I'd do something like:
def feedtype(request, feedtype, page=0):
paginator =
ObjectPaginator(
Item.objects.filter(
feed__feedtype__feedtype__iexact=re.sub('(s$|S$)',
'',
feedtype
)
).order_db('-time'), 15
)
return render_to_response(
'planetx/feedtypepage.html',
{
'realname': "Planet X",
'feedtype': feedtype,
'items': paginator.get_page(page),
'pages': {
'nextpage':
paginator.has_next_page(page),
'nextpagenumber': (page + 1),
'previouspage':
paginator.has_previous_page(page),
'previouspagenumber': (page -1)
},
}
)
Which looks like a lot more - but is just laid out easier and makes it
easier to edit later. More lines aren't neccessarily evil :)
Not sure that's too pythonic, but it means that I can read it!
Cheers,
