Display 2 random items from Postgres DB

I am building a test app to help me learn RoR.

In the app, I want to display 2 random images from the db.

First question is, where do I put this method? in the model or the controller? (right now it's in the Model)

here is the method: def makematch @objects = Object.find(:all, :limit => 2, :order => "RANDOM()") end

I think this will find 2 records and I can create two hashes to pull the appropriate avatar_urls

second question is once I have the method, how do I access it in the view?

Totally confused in this.

I moved the logic to the view which basically works:

The initial assignment returns #<ActiveRecord::Relation::ActiveRecord_Relation_Object:0x00000101f97908> on screen above the images. How can I get this logic to work from the model?
