ユーザー管理システム

ほとんどすべてのアプリケーションではユーザー、ロール、パーミッションなど何らかのセキュリティもしくは認証システムを提供する必要があります。基本的なユーザー管理とセキュリティシステムを提供するいくつかのモデルの例です。

class User extends Doctrine_Record { public function

setTableDefinition() { $this->hasColumn('username', 'string', 255, array( 'unique' => true ) ); $this->hasColumn('password', 'string', 255); } }

class Role extends Doctrine_Record { public function setTableDefinition() { $this->hasColumn('name', 'string', 255); } }

class Permission extends Doctrine_Record { public function setTableDefinition() { $this->hasColumn('name', 'string', 255); } }

class RolePermission extends Doctrine_Record { public function setTableDefinition() { $this->hasColumn('role_id', 'integer', null, array( 'primary' => true ) ); $this->hasColumn('permission_id', 'integer', null, array( 'primary' => true ) ); }

public function setUp()
{
    $this->hasOne('Role', array(
            'local' => 'role_id',
            'foreign' => 'id'
        )
    );
    $this->hasOne('Permission', array(
            'local' => 'permission_id',
            'foreign' => 'id'
        )
    );
}

}

class UserRole extends Doctrine_Record { public function setTableDefinition() { $this->hasColumn('user_id', 'integer', null, array( 'primary' => true ) ); $this->hasColumn('role_id', 'integer', null, array( 'primary' => true ) ); }

public function setUp()
{
    $this->hasOne('User', array(
            'local' => 'user_id',
            'foreign' => 'id'
        )
    );
    $this->hasOne('Role', array(
            'local' => 'role_id',
            'foreign' => 'id'
        )
    );
}

}

class UserPermission extends Doctrine_Record { public function setTableDefinition() { $this->hasColumn('user_id', 'integer', null, array( 'primary' => true ) ); $this->hasColumn('permission_id', 'integer', null, array( 'primary' => true ) ); }

public function setUp()
{
    $this->hasOne('User', array(
            'local' => 'user_id',
            'foreign' => 'id'
        )
    );
    $this->hasOne('Permission', array(
            'local' => 'permission_id',
            'foreign' => 'id'
        )
    );
}

}

YAMLフォーマットでの例は次の通りです。[doc yaml-schema-files :name]の章でYAMLの詳細を読むことができます:

User: columns: username: string(255) password: string(255) relations:

Roles: class: Role refClass: UserRole foreignAlias: Users Permissions: class: Permission refClass: UserPermission foreignAlias: Users

Role: columns: name: string(255) relations: Permissions: class: Permission refClass: RolePermission foreignAlias: Roles

Permission: columns: name: string(255)

RolePermission: columns: role_id: type: integer primary: true permission_id: type: integer primary: true relations: Role: Permission:

フォーラムアプリケーション

カテゴリ、ボードと、スレッドと投稿機能を持つフォーラムアプリケーションの例は次の通りです:

class Forum_Category extends Doctrine_Record { public function

setTableDefinition() { $this->hasColumn('root_category_id', 'integer', 10); $this->hasColumn('parent_category_id', 'integer', 10); $this->hasColumn('name', 'string', 50); $this->hasColumn('description', 'string', 99999); }

public function setUp()
{
    $this->hasMany('Forum_Category as Subcategory', array(
            'local' => 'parent_category_id',
            'foreign' => 'id'
        )
    );
    $this->hasOne('Forum_Category as Rootcategory', array(
            'local' => 'root_category_id',
            'foreign' => 'id'
        )
    );
}

}

class Forum_Board extends Doctrine_Record { public function setTableDefinition() { $this->hasColumn('category_id', 'integer', 10); $this->hasColumn('name', 'string', 100); $this->hasColumn('description', 'string', 5000); }

public function setUp()
{
    $this->hasOne('Forum_Category as Category', array(
            'local' => 'category_id',
            'foreign' => 'id'
        )
    );
    $this->hasMany('Forum_Thread as Threads',  array(
            'local' => 'id',
            'foreign' => 'board_id'
        )
    );
} 

}

class Forum_Entry extends Doctrine_Record { public function setTableDefinition() { $this->hasColumn('author', 'string', 50); $this->hasColumn('topic', 'string', 100); $this->hasColumn('message', 'string', 99999); $this->hasColumn('parent_entry_id', 'integer', 10); $this->hasColumn('thread_id', 'integer', 10); $this->hasColumn('date', 'integer', 10); }

public function setUp()
{
    $this->hasOne('Forum_Entry as Parent',  array(
            'local' => 'parent_entry_id',
            'foreign' => 'id'
        )
    );
    $this->hasOne('Forum_Thread as Thread', array(
            'local' => 'thread_id',
            'foreign' => 'id'
        )
    );
}

}

class Forum_Thread extends Doctrine_Record { public function setTableDefinition() { $this->hasColumn('board_id', 'integer', 10); $this->hasColumn('updated', 'integer', 10); $this->hasColumn('closed', 'integer', 1); }

public function setUp()
{
    $this->hasOne('Forum_Board as Board', array(
            'local' => 'board_id',
            'foreign' => 'id'
        )
    );

    $this->ownsMany('Forum_Entry as Entries', array(
            'local' => 'id',
            'foreign' => thread_id'
        )
    );
}

}

まとめ

これらの実際の世界のスキーマの例によってDoctrineの実際のアプリケーションを使うことに役立つことを願っております。この本の最後の章では[doc coding-standards コーディング規約]を検討します。コーディング規約はあなたのアプリケーションにもお勧めします。コードの一貫性が大切であることを覚えておいてください！
