Call populate on any ActiveRecord model to fill it with data. Pass the number of records you want to create, and a block to set the attributes. You can nest calls to handle associations and use ranges or arrays to randomize the values.

  Person.populate(3000) do |person|
    person.name = "John Doe"
    person.gender = ['male', 'female']
    Project.populate(10..30, :per_query => 100) do |project|
      project.person_id = person.id
      project.due_at = 5.days.from_now..2.years.from_now
      project.name = Populator.words(1..3).titleize
      project.description = Populator.sentences(2..10)
    end
  end

The following options are supported.

• :per_query - limit how many records are inserted per query, defaults to 1000

Populator::Factory is where all the work happens.
