[入門][続き２]rails3でコントローラ作成してみました！
( Ruby )お勉強のつづきです。
rails3フレームワークを指定したディレクトリにインストールします。 コマンドはrailsを利用してもろもろ作成していきます。
[nakajijapan] #rails new test ・ ・ ・ Using rack-ssl (1.3.2) Using rdoc (3.9.4) Using thor (0.14.6) Using railties (3.1.0) Installing coffee-rails (3.1.1) Installing jquery-rails (1.0.14) Using rails (3.1.0) Installing sass (3.1.8) Installing sass-rails (3.1.4) Using sqlite3 (1.3.4) Installing turn (0.8.2) Installing uglifier (1.0.3) Your bundle is complete! Use `bundle show [gemname]` to see where a bundled gem is installed.
その後、コントローラを導入してみます。 処理内容としては顧客情報のCRUDをやらせましょう。
[nakajijapan] #rails generate scaffold customer name:string email:string address:text [/var/www/spec]
/usr/local/Cellar/ruby/1.9.2-p290/lib/ruby/gems/1.9.1/gems/rack-1.3.4/lib/rack/backports/uri/common_192.rb:53: warning: already initialized constant WFKV_
invoke active_record
create db/migrate/20111004120942_create_customers.rb
create app/models/customer.rb
invoke test_unit
create test/unit/customer_test.rb
create test/fixtures/customers.yml
route resources :customers
invoke scaffold_controller
create app/controllers/customers_controller.rb
invoke erb
create app/views/customers
create app/views/customers/index.html.erb
create app/views/customers/edit.html.erb
create app/views/customers/show.html.erb
create app/views/customers/new.html.erb
create app/views/customers/_form.html.erb
invoke test_unit
create test/functional/customers_controller_test.rb
invoke helper
create app/helpers/customers_helper.rb
invoke test_unit
create test/unit/helpers/customers_helper_test.rb
invoke assets
invoke coffee
create app/assets/javascripts/customers.js.coffee
invoke scss
create app/assets/stylesheets/customers.css.scss
invoke scss
create app/assets/stylesheets/scaffolds.css.scss
もろもろできちゃいましたね。これでCRUDの処理系は作成し終わっちゃうことになりました。
お継ぎはrakeっていうコマンドを利用して、顧客テーブルをDBに反映させます。すごい便利ですね。 その前にコマンド群をbrewでインストールしているために、若干パスが通っているかのチェックと あるファイルを要求させないとうまく動かないので入れておきます。
vi /usr/local/bin/rake require 'rake/dsl_definition'
DB反映
[nakajijapan] #rake db:migrate [/var/www/spec/config] (in /private/var/www/spec) rake aborted! Please install the mysql adapter: `gem install activerecord-mysql-adapter` (mysql is not part of the bundle. Add it to Gemfile.) Tasks: TOP => db:migrate => db:load_config (See full trace by running task with --trace)
ひゃっほーー。
・・・・！！！！！
アボンしました。
gemで以下のDBに関するプラグイン郡を入れてみることにします。
[nakajijapan] #sudo gem install activerecord-mysql-adapter [/var/www/spec/config] ERROR: Could not find a valid gem 'activerecord-mysql-adapter' (>= 0) in any repository ERROR: Possible alternatives: activerecord-jdbcmysql-adapter, activerecord-odbc-adapter, activerecord-jdbc-adapter, activerecord-jdbcmssql-adapter, activerecord-jdbch2-adapter [nakajijapan] #gem install activerecord-jdbcmysql-adapter, activerecord-odbc-adapter, activerecord-jdbc-adapter, activerecord-jdbcmssql-adapter, activerecord-jdbch2-adapter [/var/www/spec/config] ERROR: Could not find a valid gem 'activerecord-jdbcmysql-adapter,' (>= 0) in any repository ^CERROR: Interrupted [nakajijapan] #gem install activerecord-jdbcmysql-adapter activerecord-odbc-adapter activerecord-jdbc-adapter activerecord-jdbcmssql-adapter activerecord-jdbch2-adapter [/var/www/spec/config] Fetching: activerecord-jdbc-adapter-1.2.0.gem (100%) Fetching: jdbc-mysql-5.1.13.gem (100%) Fetching: activerecord-jdbcmysql-adapter-1.2.0.gem (100%) Successfully installed activerecord-jdbc-adapter-1.2.0 Successfully installed jdbc-mysql-5.1.13 Successfully installed activerecord-jdbcmysql-adapter-1.2.0 Fetching: activerecord-odbc-adapter-2.0.gem (100%) Successfully installed activerecord-odbc-adapter-2.0 Successfully installed activerecord-jdbc-adapter-1.2.0 Fetching: jdbc-jtds-1.2.5.gem (100%) Fetching: activerecord-jdbcmssql-adapter-1.2.0.gem (100%) Successfully installed jdbc-jtds-1.2.5 Successfully installed activerecord-jdbcmssql-adapter-1.2.0 Fetching: jdbc-h2-1.3.154.gem (100%) Fetching: activerecord-jdbch2-adapter-1.2.0.gem (100%) Successfully installed jdbc-h2-1.3.154 Successfully installed activerecord-jdbch2-adapter-1.2.0 9 gems installed Installing ri documentation for activerecord-jdbc-adapter-1.2.0...

これも必要らしい（あ、忘れた。。。）
sudo gem install bundler
もう一度DBに反映させてみます。
[nakajijapan] #rake db:migrate [/var/www/spec] == CreateCustomers: migrating ================================================ -- create_table(:customers) -> 0.1567s == CreateCustomers: migrated (0.1568s) =======================================
ひゃっほー！！
DBでもチェックしてみます。
mysql> desc customers; +------------+--------------+------+-----+---------+----------------+ | Field | Type | Null | Key | Default | Extra | +------------+--------------+------+-----+---------+----------------+ | id | int(11) | NO | PRI | NULL | auto_increment | | name | varchar(255) | YES | | NULL | | | email | varchar(255) | YES | | NULL | | | address | text | YES | | NULL | | | created_at | datetime | YES | | NULL | | | updated_at | datetime | YES | | NULL | | +------------+--------------+------+-----+---------+----------------+ 6 rows in set (0.01 sec)
できましたね。
簡単にできるのはいいけど、多少の融通きけるものであってほしいけどどうなんでしょうね！！！
次はまた今度。
