How to get model name out of array

Question

I have a search controller something like this:

def index @foos = Foo.search @bars = Bar.search @search = [@foos, @bars] end

And in my search index:

<% @search.each do |s| %> <% s.each do |s| %> <% s.name %> <% end %> <% end %>

How can I write an if statement to find arrays only from the Foo model?

<% if s.modelname == "Foo" %> ?

Setting <%= s.each do %> shows that the array does have it's model name.

Try This :

<% if s.class.to_s == "Foo" %>

Why the to_s stuff when you can say s.class == Foo or better s.is_a? Foo instead?

Try This:

<% @search.each do |s| %> <% if s[0].class.to_s == "Foo" %> <% s.each do |s| %> <% s.name %> <% end %> <% end %>

With that we are checking the condition before entering into the sub loop ,So It will reduces the loop iterations.
