How do I set the size of a field of type string in a migration? Ex: 

class CreateRooms < ActiveRecord::Migration
def change
create_table :rooms do |t|
  t.string :title
  t.string :location
  t.text :description

  t.timestamps
end
end
end

How can I say that the title field is varchar (50)

Use the limit : 

t.string :title, limit: 50
