Question

I have two different types of objects, say of classes Object1 and Object2. I want to be able to render, mix, and sort them in the same container.

In the controller action:

@objects1=Object1.reorder('created_at DESC')
@objects2=Object2.reorder('created_at DESC')

In the view:

 <div class="container">
   <%= render @objects1 %>
   <%= render @objects2 %>
 </div>

What SQL/ActiveRecord statement can I use so that they are sorted against one another?

Answer 1

How about just combining them into a single array and then sorting the array?

@all_objects = objects1.concat(objects2).sort!{ |a,b| a.created_at <=> b.created_at }
