class CreateCrews < ActiveRecord::Migration
  def self.up
    create_table :crews do |t|
      t.string :title
      t.text :description
      t.boolean :adult
      t.boolean :private
      t.integer :gender_id
      t.boolean :approved,:default => false
      t.timestamps
    end
  end
  def self.down
    drop_table :crews
  end
end


class Crew < ActiveRecord::Base
  has_many :users,:through => :crew_users
  belongs_to :user

  default_scope where(:approved => true)
end

当我进入控制台并创建新记录时,“已批准”属性设置为true,为什么？

如何将其自动设置为默认值(false),如我的迁移文件中所示？
