1、文件路径:advanced/console/migrations/m130524_201442_init.php
2、补充点:增加约束“username”“email”验证的唯一性:
原代码:
<?php use yii\db\Schema; use yii\db\Migration; class m130524_201442_init extends Migration { public function up() { $tableOptions = null; if ($this->db->driverName === ‘mysql‘) { // http://stackoverflow.com/questions/766809/whats-the-difference-between-utf8-general-ci-and-utf8-unicode-ci $tableOptions = ‘CHARACTER SET utf8 COLLATE utf8_unicode_ci ENGINE=InnoDB‘; } $this->createTable(‘{{%user}}‘, [ ‘id‘ => Schema::TYPE_PK, ‘username‘ => Schema::TYPE_STRING . ‘ NOT NULL‘, ‘auth_key‘ => Schema::TYPE_STRING . ‘(32) NOT NULL‘, ‘password_hash‘ => Schema::TYPE_STRING . ‘ NOT NULL‘, ‘password_reset_token‘ => Schema::TYPE_STRING, ‘email‘ => Schema::TYPE_STRING . ‘ NOT NULL‘, ‘status‘ => Schema::TYPE_SMALLINT . ‘ NOT NULL DEFAULT 10‘, ‘created_at‘ => Schema::TYPE_INTEGER . ‘ NOT NULL‘, ‘updated_at‘ => Schema::TYPE_INTEGER . ‘ NOT NULL‘, ], $tableOptions); } public function down() { $this->dropTable(‘{{%user}}‘); } }
补充后的代码:
<?php use yii\db\Schema; use yii\db\Migration; class m130524_201442_init extends Migration { public function safeUp() { $tableOptions = null; if ($this->db->driverName === ‘mysql‘) { // http://stackoverflow.com/questions/766809/whats-the-difference-between-utf8-general-ci-and-utf8-unicode-ci $tableOptions = ‘CHARACTER SET utf8 COLLATE utf8_unicode_ci ENGINE=InnoDB‘; } $this->createTable(‘{{%user}}‘, [ ‘id‘ => Schema::TYPE_PK, ‘username‘ => Schema::TYPE_STRING . ‘ NOT NULL‘, ‘auth_key‘ => Schema::TYPE_STRING . ‘(32) NOT NULL‘, ‘password_hash‘ => Schema::TYPE_STRING . ‘ NOT NULL‘, ‘password_reset_token‘ => Schema::TYPE_STRING, ‘email‘ => Schema::TYPE_STRING . ‘ NOT NULL‘, ‘status‘ => Schema::TYPE_SMALLINT . ‘ NOT NULL DEFAULT 10‘, ‘created_at‘ => Schema::TYPE_INTEGER . ‘ NOT NULL‘, ‘updated_at‘ => Schema::TYPE_INTEGER . ‘ NOT NULL‘, ], $tableOptions); $this->createIndex(‘username‘, ‘{{%user}}‘, ‘username‘, true); $this->createIndex(‘email‘, ‘{{%user}}‘, ‘email‘, true); } public function safeDown() { $this->dropTable(‘{{%user}}‘); } }
