Example application
All patterns and instructions in this documentation refer to the filterrific demo Rails application below. You can view a live demo, and the source for the demo app.
I have included only the parts of the code required to demonstrate Filterrific. In a production app you would have to add a lot more code to handle permissions, strong params, etc.
The Student model is the primary model which we will filter. It belongs to
the Country class as shown below:

# app/models/student.rb
class Student < ActiveRecord::Base
# db columns:

# string: first_name

belongs_to :country
end
Country
The Country class represents the country a Student belongs to, e.g.,
“Canada”, “United States”, and “Australia”.
Not all students belong to a country.
