chap_testが作成済み
/test/functional/main_controller_test.rb

    @first_id = members(:one).id
#:first から　:one へ変更する。

scaffold-03再度まとめ

aptanaでNewprojectとして作成する。
mysqlへログインする。

$mysql5 -u root
mysql> show databases;

/lib/tasks/base.rakeを下記の内容にて作成する。

env = ENV['RAILS_ENV'] || 'development'
database = "chap_#{env}"

task :connect_db => [:environment] do
  ActiveRecord::Base.establish_connection(
    :adapter => 'mysql',
    :host => 'localhost',
    :username => 'root',
    :database => 'mysql',
    :socket => '/opt/local/var/run/mysql5/mysqld.sock'
   )
end

task :setup_db => [:connect_db] do
  ActiveRecord::Schema.define do
    create_database database
  end
end

task :destroy_db => [:connect_db] do
  ActiveRecord::Schema.define do
    drop_database database
  end
end

データベースを作成する。

$ rake setup_db
(in /Users/monote/dev/rails/chap0425)
-- create_database("chap_development")
   -> 0.0453s
monote$ 

モデルを作成する。

$ ruby script/generate model member

データベースの要素を作成する。

/db/migrate/001_create_members.rb

class CreateMembers < ActiveRecord::Migration
  def self.up
    create_table :members do |t|
      t.column :text, :string
      t.column :create_at, :datetime      
    end
  end

  def self.down
    drop_table :members
  end
end

テーブル／項目作成。

$ rake db:migrate
(in /Users/monote/dev/rails/chap0425)
== CreateMembers: migrating ===================================================
-- create_table(:members)
   -> 0.0027s
== CreateMembers: migrated (0.0030s) ==========================================

スキャッフォールド作成。

$ ruby script/generate scaffold Member main
      exists  app/controllers/
      exists  app/helpers/
      create  app/views/main
      exists  app/views/layouts/

■なぜか再起動するとPATHが通っていないので

$export PATH=$PATH:/opt/local/lib/mysql5/bin

■mysqlログイン

To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:
/opt/local/lib/mysql5/bin/mysqladmin -u root password 'new-password'
/opt/local/lib/mysql5/bin/mysqladmin -u root -h mono-no-macbook.local password 'new-password'

Alternatively you can run:
/opt/local/lib/mysql5/bin/mysql_secure_installation

which will also give you the option of removing the test
databases and anonymous user created by default.  This is
strongly recommended for production servers.

See the manual for more instructions.

You can start the MySQL daemon with:
cd /opt/local ; /opt/local/lib/mysql5/bin/mysqld_safe &

You can test the MySQL daemon with mysql-test-run.pl
cd mysql-test ; perl mysql-test-run.pl

Please report any problems with the /opt/local/lib/mysql5/bin/mysqlbug script!
