Hello!

In my controller, I have a model that preloads (or eager loads?) its  
respective child members.

class Parent \< ApplicationController

def show  
@parent = Parent.find(:all, :include =\> :children)  
end  
end

In my view, I need to display a specific child by searching for it in  
@parent.children. Right now I am using ActiveRecord’s find, which  
results in an additional query to the database.

@parent.children.find(:all, :conditions =\> [‘name = ?’, jonas])

So would it be possible to use Enumerable’s find method to search the  
eagerly loaded children instead of using ActiveRecord’s find?

Thanks!  
Mike

Yes! @parent.children.to\_a.find #\<= this is Enumerable’s find
