This doesn't avoid sorting between the different cases in the controller, but it does make the code in the controller more readable and cuts down on the code there. So linking to the specific querie using the following: 'great') %> will link to this url /items?average_rating=great which will access the following if statement in the items_controller: def index if params[:average_rating] == "great" @items = Item.find_items_that_are_great else @items = Item.find(:all) ... end The else part of the statement returns RESTful results as expected from /items if the initial condition/querie is not met. However, if the first condition of the if statement is met/true "find_items_that_are_great" in models/items.rb returns results in accordance with the following which is the specific querie: def self.find_items_that_are_great find(:all, :order => 'score desc', :conditions => 'score>4' ) end The code is implemented here: http://isitgreat.heroku.com/items?average_rating=great By using an if statement in the controller, as detailed below, it is possible to move code to the model. This doesn’t avoid sorting between the different cases in the controller, but it does make the code in the controller more readable and cuts down on the code there.

So linking to the specific querie using the following:

‘great’) %>

will link to this url /items?average_rating=great which will access the following if statement in the items_controller:

def index
if params[:average_rating] == “great”
@items = Item.find_items_that_are_great
else
@items = Item.find(:all)
…
end

The else part of the statement returns RESTful results as expected from /items if the initial condition/querie is not met.

However, if the first condition of the if statement is met/true “find_items_that_are_great” in models/items.rb returns results in accordance with the following which is the specific querie:

def self.find_items_that_are_great
find(:all, :order => ‘score desc’, :conditions => ‘score>4′ )
end

The code is implemented here:

http://isitgreat.heroku.com/items?average_rating=great
