Rails – モデル生成とマイグレーション

2021-03-03 / tau / コメントする

概要

Railsでは、データベースのテーブルをモデルを通して扱う。そのための開発時点での操作は以下のとおり。

モデルの生成・操作
マイグレーションによるテーブルの生成・操作

モデルの生成・削除

モデルの生成

テーブルに対して1つのモデルを生成する。

基本形は以下のコマンド。

rails generate model model_name

生成時にテーブルのフィールド名とフィールドの型を指定する場合(フィールド指定の間はスペース)。

rails generate model model_name col1:type col2:type ...

フィールドの型

primary_key
binary, boolean
date, datetime, time, timestamp
decimal, float, integer
string, text

生成されるファイル

実行後、モデルクラスとマイグレーションの2つのクラスファイルが生成される。

モデルクラスファイル

app_name/app/models/model_name

ファイルの内容はクラス定義
クラス名はモデル名のパスカルケース(ModelName)
ApplicationRecordを継承

class ModelName < ApplicationRecord
end

1 2	class ModelName < ApplicationRecord end

マイグレーションファイル

app_name/db/migrate/yyyymmddhhmmss_create_model_name.rb

テーブルを扱うマイグレーションクラスが定義される
マイグレーションクラスはActiveRecordモジュールのMigrationクラスを継承している
マイグレーションクラスのクラス名はCreateModelNames
- パスカルケース
- 最後にsがついた複数形
マイグレーションクラスのcreate_tableはDSL(ドメイン固有言語、Railsdoc)
- テーブル名はスネークケースでモデル名の複数形
- 生成時にフィールド名と型を指定した場合、create_tableブロック内でフィールドが定義される

class CreateModelNames < ActiveRecord::Migration[5.1]
  def change
    create_table :model_names do |t|
      t.string :col1
      t.string :col2
      .....

      t.timestamps
    end
  end
end

class CreateModelNames < ActiveRecord::Migration[5.1]

def change

create_table :model_names do |t|

t.string :col1

t.string :col2

.....

t.timestamps

end

モデルの削除

モデルの削除は以下のコマンドで、モデルクラスファイルとマイグレーションファイルが削除される。

rails destroy model model_name

ただしデータベース上のテーブルは削除されない。

テーブルの生成・削除

テーブルの生成

以下のコマンドで、マイグレーションファイルの設定に従ってデータベースにテーブルが生成される。

rails db:migrate

モデル生成時にフィールドを指定しなかった場合やモデル生成後にフィールドを追加する場合は、マイグレーションファイルにフィールドを追加する。

class CreateDemoRecords < ActiveRecord::Migration[6.1]
  def change
    create_table :demo_records do |t|
      t.型 :フィールド名
  
      t.timestamps
    end
  end
end

class CreateDemoRecords < ActiveRecord::Migration[6.1]

def change

create_table :demo_records do |t|

t.型 :フィールド名

t.timestamps

end

一度migrateした後にマイグレーションファイルを修正して再度migrateしても反映されない。一旦rails db:rollbackでテーブル生成前の状態に戻してからマイグレーションファイルを修正して再度実行。

テーブルの削除

ロールバック

rails db:rollbackで直前に生成したテーブルを削除

MySQLでの削除

MySQLのコンソールでDROP TABLEを実行

マイグレーション

model_nameモデルのmodel_namesテーブルを例にとる。

model_nameモデルを削除
- rails destroy model model_name
以下のコマンドでダミーのマイグレーションファイルを生成
- rails generate migration 任意の名前
マイグレーションファイルのdef changeブロックに以下を追加
- drop_table: model_names
rails db:migrationを実行
db/migrate/マイグレーションファイルを削除

実行例

モデルの生成

demo_recordという名前でモデルを生成する。このモデルはname:stringとage:integerの2つのフィールドを持つモデルを生成する。

[vagrant@localhost demo_app]$ rails g model demo_record name:string
Running via Spring preloader in process 24003
      invoke  active_record
      create    db/migrate/20210303061311_create_demo_records.rb
      create    app/models/demo_record.rb
      invoke    test_unit
      create      test/models/demo_record_test.rb
      create      test/fixtures/demo_records.yml

[vagrant@localhost demo_app]$ rails g model demo_record name:string

Running via Spring preloader in process 24003

invoke active_record

create db/migrate/20210303061311_create_demo_records.rb

create app/models/demo_record.rb

invoke test_unit

create test/models/demo_record_test.rb

create test/fixtures/demo_records.yml

モデルファイル

モデルファイルがapp/modelsの下に作成される。モデルファイル名はモデル生成時のモデル名のスネークケースになっている。

[vagrant@localhost demo_app]$ ls app/models/
application_record.rb  concerns  demo_record.rb

1 2	[vagrant@localhost demo_app]$ ls app/models/ application_record.rb concerns demo_record.rb

モデルファイルの内容はモデルクラスの定義で、生成当初は空の定義。モデルクラス名がモデル名のパスカルケースになっている。

class DemoRecord < ApplicationRecord
end

1 2	class DemoRecord < ApplicationRecord end

マイグレーションファイル

マイグレーションファイルがdb/migrateの下に作成される。

[vagrant@localhost demo_app]$ ls db/migrate/
20210303071205_create_demo_records.rb

1 2	[vagrant@localhost demo_app]$ ls db/migrate/ 20210303071205_create_demo_records.rb

マイグレーションファイルの内容はテーブル生成クラスの定義で、create_tableブロックの中でフィールドの名前と型を指定している。

モデル名demo_recordに対して生成されるテーブルクラス名はCreateDemoRecordsで、接頭辞Createにモデル名に複数形のsがついたパスカルケース
create_tableブロックでフィールドの型とフィールド名を定義

class CreateDemoRecords < ActiveRecord::Migration[6.1]
  def change
    create_table :demo_records do |t|
      t.string :name

      t.timestamps
    end
  end
end

class CreateDemoRecords < ActiveRecord::Migration[6.1]

def change

create_table :demo_records do |t|

t.string :name

t.timestamps

end

テーブルの生成～マイグレーション

rails db:migrateコマンドにより、マイグレーションファイルの設定に基づいてテーブルを生成する。

[vagrant@localhost demo_app]$ rails db:migrate
== 20210303063040 CreateDemoRecords: migrating ================================
-- create_table(:demo_records)
   -> 0.0329s

Vagrant – Atomを使う

2021-03-01 / tau / コメントする

方法1～共有フォルダ－

共有フォルダにあるファイルをホスト側のAtomで開く。

ただし、Railsのファイルを編集している場合、いったんRailsサーバーを立ち上げなおさないと内容が反映されないという症状が出た。

方法2～AtomからFTP接続

remote-ftpのインストール

AtomにFTP接続用のパッケージをインストールして接続する。

手順

File → Settings→Installからremote-ftpを検索してインストール
AtomからホストのVirtualBoxの仮想マシンフォルダーを開く(C:\vagrant\centos7)
Packages→Remote FTP → Create SFTP config file
Atomで開いた.ftpconfigファイルの内容を編集

.ftpconfigファイルの編集

.ftpconfigファイルの編集に必要な情報は、コンソールからvagrant ssh-configコマンドで表示させる。

C:\vagrant\centos7>vagrant ssh-config
Host default
  HostName 127.0.0.1
  User vagrant
  Port 2222
  UserKnownHostsFile /dev/null
  StrictHostKeyChecking no
  PasswordAuthentication no
  IdentityFile C:/vagrant/centos7/.vagrant/machines/default/virtualbox/private_key
  IdentitiesOnly yes
  LogLevel FATAL

C:\vagrant\centos7>vagrant ssh-config

Host default

HostName 127.0.0.1

User vagrant

Port 2222

UserKnownHostsFile /dev/null

StrictHostKeyChecking no

PasswordAuthentication no

IdentityFile C:/vagrant/centos7/.vagrant/machines/default/virtualbox/private_key

IdentitiesOnly yes

LogLevel FATAL

この情報に基づいて.ftpconfigを編集。

トラブル

ERBファイル

Railsのerbファイルに色がつかない。config.csonを編集してみたが効果がなかった。

原因はtree-sitter parserのバグが考えられ、以下で対処。

Settings→Coreの”Use Tree Sitter Parsers”のチェックを外す
再起動→チェックが外れているという警告は無視

Vagrant/CentOS7 – Railsのインストール

2021-02-26 / tau / コメントする

概要

Vagrant + VirtualBox + CentOSの環境にRuby、MySQLをインストール後、Railsをインストールするのにいろいろと躓きながら進めた記録。

構成

Vagrant : 2.2.14
VirtualBox : 6.1.18
Box : bento/CentOS-7.7
mysql : Ver 8.0.23 for Linux on x86_64
Ruby : ruby 3.0.0p0
Rails : Rails 6.1.3

インストール概略

階層が下のものは今回必要になったもの。

SELinux、firewalldの停止
Railsインストール
- sasscインストール
  - g++インストール
- mysql-develインストール
  - Node.jsインストール
Railsサーバー実行
- webpackerインストール
  - Node.jsインストール(再掲)
  - Yarnインストール

利用手順

アプリケーション生成

sqlite3がデフォルトで未インストールではエラーが出るため、コマンドラインでmysqlを指定。

rails new app_name -d mysql
rails new app_name --database=mysql

database.ymlの修正

データベースを使わない場合は、development、test、productionの各database:をコメントアウト／削除。

default: &default
  adapter: mysql2
  encoding: utf8mb4
  pool: <%= ENV.fetch("RAILS_MAX_THREADS") { 5 } %>
  username: root
  password: vagrant
  socket: /var/lib/mysql/mysql.sock

development:
  <<: *default
#  database: bbs_development

test:
  <<: *default
#  database: bbs_test

production:
  <<: *default
#  database: bbs_production
#  username: bbs
#  password: <%= ENV['BBS_DATABASE_PASSWORD'] %>

default: &default

adapter: mysql2

encoding: utf8mb4

pool: <%= ENV.fetch("RAILS_MAX_THREADS") { 5 } %>

username: root

password: vagrant

socket: /var/lib/mysql/mysql.sock

development:

サーバー起動・接続

ここでrails sでサーバーを起動するが、ブラウザーがつながらない。

参考サイト(Rails4.2：Vagrant上の仮想マシンで起動したRailsにホストのブラウザからアクセス出来ない)のおかげで、Railsサーバーを以下で立ち上げるとよいことが分かった。

rails s -b 0.0.0.0

概要

Vagrant + VirtualBox + CentOS7でRailsをインストールする際にNode.jsが必要になったのでインストール。

参考サイト：CentOS 7 Node.js のインストール手順 (yum を利用)

準備～nvmのインストール

nvmはNode.jsのバージョン管理ツール。Gitでnvmをクローン。

概要

firewalldはファイアーウォールの機能を提供するサービス。

ステータスの確認

ステータスの確認にはsystemctlコマンドを使う。

[vagrant@localhost ~]$ systemctl status firewalld
● firewalld.service - firewalld - dynamic firewall daemon
   Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled; vendor preset: enabled)
   Active: inactive (dead)

[vagrant@localhost ~]$ systemctl status firewalld

● firewalld.service - firewalld - dynamic firewall daemon

Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled; vendor preset: enabled)

Active: inactive (dead)

Docs: man:firewalld(1)

active (running)の場合は実行中、inactive (dead)の場合は停止中。

ステータスの設定

ステータスの設定・変更には、suでsystemctlコマンドを使う。

firewalldの有効化

有効化はsudo systemctl start firewalld。

[vagrant@localhost ~]$ sudo systemctl start firewalld

Linux – SELinux

2021-02-25 / tau / コメントする

概要

SELinuxはシステムへのアクセス制御のための機能。

ステータスの確認

SELinuxの動作状況はgetenforceコマンドで確認。

[vagrant@localhost ~]$ getenforce
Permissive

1 2	[vagrant@localhost ~]$ getenforce Permissive

ステータスは3種類。

Permissive: アクセス制御は無効、警告メッセージを表示。
Enforcing: アクセス制御が有効。
Disabled: SELinuxは無効。

ステータスの変更

一時的な設定～setenforce

suでsetenforceコマンドを使い、Permissive/Enforcingを設定。

sudo setenforce 0/1

0でPermissing、1でEnforcing

起動時の設定～/etc/selinux/config

/etc/selinux/configファイル中、SELINUXの行をコメントアウトして設定すると、起動時のステータスが設定される。

# SELINUX= can take one of these three values:
#     enforcing - SELinux security policy is enforced.
#     permissive - SELinux prints warnings instead of enforcing.
#     disabled - No SELinux policy is loaded.

# SELINUX= can take one of these three values:

# enforcing - SELinux security policy is enforced.

# permissive - SELinux prints warnings instead of enforcing.

# disabled - No SELinux policy is loaded.

Vagrant – MySQLのインストール – CentOS7

パスワードの変更

初期状態でパスワードがわからない

MySQLインストール直後にrootでログインしようとしたとき、パスワードがわからずログインできなかった。

[vagrant@localhost ~]$ mysql -u root -p
Enter password:
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)

[vagrant@localhost ~]$ mysql -u root -p

Enter password:

ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)

ログファイルの確認

初期パスワードはログファイルに残されているとのことで、ログからパスワードを確認。

By default, a MySQL installation has an anonymous user,
allowing anyone to log into MySQL without having to have
a user account created for them. This is intended only for
testing, and to make the installation go a bit smoother.
You should remove them before moving into a production
environment.

Remove anonymous users? (Press y|Y for Yes, any other key for No) : y
Success.


Normally, root should only be allowed to connect from
'localhost'. This ensures that someone cannot guess at
the root password from the network.

Disallow root login remotely? (Press y|Y for Yes, any other key for No) : y
Success.

By default, MySQL comes with a database named 'test' that
anyone can access. This is also intended only for testing,
and should be removed before moving into a production
environment.


Remove test database and access to it? (Press y|Y for Yes, any other key for No) : y

Vagrant – 共有設定・カーネル更新

2021-02-23 / tau / コメントする

概要

Vagrantの仮想環境での共有フォルダ－設定
環境はWindows10、Vagrant、VirtualBox、bento/Centos-7.7
この過程でカーネルのアップデートが必要

Vagrant初期起動

bento/Centos-7.7の前にCentos/7のBoxで共有設定をしたときにvagrant-vbguestパッケージをインストール済みだったので、GuestAdditionsの不整合は解決されている様子。

ただしkernelのバージョン不整合は解決されない。

共有設定・再起動

共有設定の最終段階
ホスト側の共有フォルダ－を作成
vagrantfileに1行追加
vagrant reloadでVagrantを再起動
仮想環境下にもフォルダーが作成され、同期される

vagrantfile設定

config.vm.synced_folder "ホスト側パス", "ゲスト側パス"

第1引数はホスト側パスで、vagrantfileからの相対パスで指定
- ホスト側で共有ディレクトリーを作成しておく必要がある
第2引数はゲストパスで、絶対パスで指定
- ゲスト側の共有ディレクトリーはVagrantが作成してくれる

Vagrant.configure("2") do |config|
  .....
  config.vm.box = "bento/centos-7.7"
  .....
  config.vm.synced_folder "./share", "/home/vagrant/share"
  .....
end

Vagrant.configure("2") do |config|

.....

config.vm.box = "bento/centos-7.7"

.....

config.vm.synced_folder "./share", "/home/vagrant/share"

.....

end

Vagrant再起動

Vagrantを再起動すると、共有フォルダ－が作成される。
