Hi,
I've got a bunch of campaigns I wish to render into an index-page.
Two diagrams have to be in each campaign (jQuery). One of them
requires a database query within a loop (the finished orders for each
day of one week).
Since its bad code to put a database query in the view, and I dont
want to work with 4 dimensional arrays, I thought about rendering each
campaign from a seperate action, with a view attached to it.
But I either get format errors on Nil if I try
<% @campaigns.each do |c| %>
<%= render :action => "get_single_campaign", :params => {:campaign_id
=> c.id} %>
<% end %>
or with no html at all if I'm using
@get_all_campaign_output = ""
@campaigns.each do |c|
@get_all_campaign_output += get_single_campaign(c.id)
end
in the controller (output is a string). I get the feeling my whole
approach is wrong, since I cant find a solution and I've been
searching for two days already. I hope some of you can tell me how to
solve this.
Thanks in advance,
Heike
