▲各種ファイルの作成

■migrateファイルの編集

座標用のフィールド属性には追加したい事があるので、migrate用ファイルを編集する。

Ruby

# ---- cpro01\db\migrate\20100118123851_create_maps.rb ----
class CreateMaps < ActiveRecord::Migration
  def self.up
    create_table :maps do |t|
      t.integer :book_id
      t.integer :user_id
      t.decimal :la, :precision => 18, :scale => 14, :default => 0
      t.decimal :lo, :precision => 18, :scale => 14, :default => 0
      t.text :title
      t.text :comment
      t.text :tag
      t.integer :netabare_flg
      t.integer :kokai_flg
      t.string :nendai
      t.text :memo
      t.integer :del_flg

      t.timestamps
    end
  end

  def self.down
    drop_table :maps
  end
end

▲7,8行目を編集
