[Rails] help for ideas of instance method or controller

I have a general question about Rails controller or instance method.


Say, I have two models,

Give
Take

Each of these has an identical set of columns like,

Give : weight:integer, day:date
Take: weight:integer, day:date

When @give = Give.new is created, I want to search if there is a
counterpart, Take, having the same values, weight and day. So I need to
define a search method somewhere.

I believe it will look like

@give = Give.new
...
if @give.search_counter #<- returns true if the counterpart exists
...
else
end

This must work for Take as well

@take = Take.new
...
if @take.search_counter #<- returns true if the counterpart exists
...
else
end


Questions:
Is it possible? I am not sure if the method works without arguments...
Where do I have to define the method? application_controller.rb maybe?
