Re: A view associated with a lot of urls

Well that should work pretty well with an SQL database. But as I said
my database is a NoSQL one, here I need to have one "table" per
category. So creating another Categorylist table just for fun and put
all the category names into, then hit it in order to check if the
category exists just seems wrong to me.
I thought of retrieving a list of the table names from the database
and check if the category the user want is in that list but for that I
must import another module.
