Boolean Validaiton : I am facing a little problem here. 
I have fetch the data from data using following code, 
    
    class CreateGrounddetails < ActiveRecord::Migration
     def change
      create_table :grounddetails do |t|
      t.string :name
      t.datetime :working_hours
      t.string :address
      t.string :contact_no
      t.string :email
      t.integer :number_of_grounds
      t.text :description
      t.boolean :featured_ground #Featured  
      t.timestamps null: false
      end
      end
      end
 
I have a boolean values stored in the field "featured_ground", now i want to fetch only the data which has "TRUE" value for "featured_ground".
How can i achieve that ?

Thank you in advance.
