Hello all. I’ve set up an inventory app and I want to be able to have
the index file display ether everything in inventory or only items on
order. So I want to populate @spares with the appropriate content then
pass it to index.html.erb
Is this the right approach? If so how do put logic into the controller
to populate @spares ?
Any help appreciated!

------------spares_controller.rb
def index @spares = Spare.find(:all) <–do this to see total inventory @spares = Spare.find(:all, :conditions => [“state = ?”, “On Order”])
<–do this to see what’s on order
…
end
-------------index.html.erb
<% for spare in @spares %>

It looks like you’re generally going in the right direction. However,
you’re setting @spares twice, so your view will only see the results of
the second #find. It’s not really clear to me what effect you’re going
for here.
I also recommend using named_scope for the “on order” items, if you’re
using Rails 2.1 or above. They’re a bad-ass way to encapsulate common
filters on your objects.

Thanks for the reply Jeremy. I didn’t mean to show that I was populating @spares twice, I was looking for a way to populate it one of the two
ways depending on what the user wanted to see.
I’ll take a look at the link you sent, might be the way to go.
Thanks again.
