I'm looking for a way to check an item in memory to see if an association loaded. I load the association in the controller and then in the view I need to check to see if the associated model loaded because I display an attribute of it. Of course, if the model didn't load, because it doesn't exist, I get an error. For example, in my controller I have thus: def list @systems = System.find(:all, :order => 'name', :include => :review) end :review belongs to a :system, which has_one :review In my view I do this: <%= link_to_if !system.review.blank?, system.name, :action => 'edit', :id => system.review %> This doesn't work, because it queries the database each time (I'm looping through a collection of 200 items). So my question is, how can I get the link_to_if to check the memory object of review, or is there a different way to test this? I would think that I could just check what's in memory and not have to run another query for each item if I already loaded all of them. Thanks.
