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!
...Bill
------------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 %>
<tr>
<td><%=h spare.name %></td>
<td><%=h spare.partno %></td>
<td><%=h spare.state %></td>
...
</tr>
<% end %>

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. http://ryandaigle.com/articles/2008/3/24/what-s-new-in-edge-rails-has-finder-functionality -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

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. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
