Custom dynamic routing and get ids from url

I have a model name "profit" and it has a table name profits and 3 column of the table "product_id", "client_id", "grossprofit"

Now in my index.html.erb page I have option for show as

<td><%= link_to 'Show', profit %></td>

when I click on the show link i go to show page and link become

http://localhost:3000/profits/1
http://localhost:3000/profits/2

that is i am getting id of profits table but I need product_id and client_id in my url like below

http://localhost:3000/profits/3/5

where 3 will be product_id and 5 will be client_id

What changes I have to do to get this url and how can I get product_id and client_id from the url in show action of the controller?

Association among the models are 

product: has_many  profits
client: has_many profits
profit: belongs to product and client

Routes

As HarsHarl & cenyongh suggested, you'd be better looking at Nested Resources

The problem you've got is that you can't access the product_id and client_id vars, unless they're stored in a session. Because of this, you'll have to pass them through the URL

I'd use this:

resources :profits do
    get ":product_id/:client_id", to: "show"
end

This will create this route:

/profits/13/5

More importantly, it will pass these params: product_id and client_id to the show action

The routes.rb

resources :profits do    
  get ":product_id/:client_id", :action => :show, :as => :show, :on => :collection
end

The view

<%= link_to 'Show', show_profits_path(profit.product_id, profit.client_id) %>

The development log when clicking the link is 

Started GET "/profits/5/3" for 127.0.0.1 at 2014-01-04 20:42:10 +0800
Processing by ProfitsController#show as HTML
  Parameters: {"product_id"=>"5", "client_id"=>"3"}

end
