Using session variables vs passing parameters via URL


#1

Hi,
I have been tweaking my index view in order to narrow down the amount of
data displayed. The obvious first step was to add will-paginate, but
then I
added a couple of select boxes to narrow things down a bit more based on
categories. Somewhere in the midst of all of this I discovered the way
cool
feature of named routes that allows me to pass parameters into the named
route. So I am using things like new_document_path(:category =>
@category,
:prefix => @prefix) in order to pass the values of @category and @prefix
from my “index” view into my “new” view.

I am trying to do the same thing with the named route in a form (i.e.
form_for (document_path(:prefix => @prefix, ;category => @category,
:page =>
@page) …) and am running into some problems. It may be the case that
I
cannot use this feature for the #create action. I’m not sure yet. But
as
I’ve started thinking about this I’ve started to wonder if I’m going
down
the best path.

Would it make more sense to store @prefix, @category, @page, and
whatever
else I think I might want to pass around in the session? Or should I
keep
going down this route?

I should point out that the purpose of these parameters is solely to
narrow
down the number of items displayed. They don’t affect anything other
than
the view the user sees as (s)he navigates back and forth between the
#index
view, the #new view, the #index view for some other controller etc…

Hi Patrick,

Session variables are awefull, please don’t use them.
Just think of a user passing the url to another user expecting
that the other will see the same content but with weird session
variables that wouldn’t happen.

ciao, tom
