From my home page you can choose a tire size your looking for this
takes you to the tire_results page.
now this page is built on what tires are in @tire. So you may be looking
at all the 14" tires I have. But you will be looking at singles, pairs
and sets. I would like my customers to be able to narrow down what there
looking for like just find all the set of 4’s or all the pairs.
From the home page a :id gets past to tire_results page… bringing back
all those tires… how can I reuse this same page to render the :id
tires and narrow it down to were t.qty =='s 2 or 1 or what ever.
You can just pass it into the view as a hidden param.
like a session variable or some thing?
Well I was thinking that maybe I could build a route that went
controller/action/id/qty
So if :qty was absent it would use the general array of tires with that
:id param and if :qty was present it would then delete all elements that
didn’t meet the qty sent.
Currently the @tires array gets built on were size equals :id. I’m not
sure how to say if :qty != nil{ delete_if( |t|
t.qty != :qty}

I’d avoid session variables.

That is a nicer way of looking at things. It also means (unlike using
a hidden form parameter) that people can link to that precise page,
bookmark it etc.

That’s pretty much exactly what you’d do (or you might want to add the
condition on qty into what fetches tries from the database)
