我正在尝试使用控制器方法创建数据库表。每次运行我的代码时，都会收到以下错误消息。 我正在使用Yii2 Framework
SQLSTATE [HY000]：常规错误：1215无法添加外键约束 正在执行的SQL是：CREATE TABLE
name（typevarchar（64）not null，descriptionint not null，rule_nametext，datavarchar（64），created_attext，updated_atint not null，actionInstallint not null）CHARACTER SET utf8 COLLATE utf8_unicode_ci ENGINE = InnoDB错误信息：数组（ [0] =＆gt; HY000 [1] =＆gt; 1215 [2] =＆gt;无法添加外键约束）引起：PDOException
SQLSTATE [HY000]：常规错误：1215无法添加外键约束
在 /home/offneo/Projects/MODULEMANAGER/Product/Software/vendor/yiisoft/yii2/db/Command.php 在第844行
以下是控制器方法$db = Yii::$app->db;
$tableOptions = null;
$status = true;
if ($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';
}
// Table auth_rule
if ( $db->getTableSchema('auth_rule') === null ) {
$status &= (bool) $db->createCommand()->createTable('auth_rule', [
'name' => 'varchar(64) not null',
'data' => "text",
'created_at' => "int",
'updated_at' => "int",
'PRIMARY KEY (name)'
], $tableOptions)->execute();
$status &= (bool) $db->createCommand()->createIndex('name_UNIQUE', 'auth_rule', 'name', true)->execute();
}
// Table auth_item
if ( $db->getTableSchema('auth_item') === null ) {
$status &= (bool) $db->createCommand()->createTable('auth_item', [
'name' => 'varchar(64) not null',
'type'=>'int not null',
'description' => 'text',
'rule_name' => "varchar(64)",
'data'=>'text',
'created_at' => 'int not null',
'updated_at' => 'int not null'
], $tableOptions)->execute();
$status &= (bool) $db->createCommand()->addPrimaryKey('name_pk', 'auth_item', 'name')->execute();
// $status &= (bool) $db->createCommand()->addForeignKey('fk_auth_item_auth_rule1_idx', 'auth_item', 'rule_name', 'auth_rule', 'name', 'SET NULL', 'CASCADE')->execute();
// $status &= (bool) $db->createCommand()->createIndex('fk_auth_item_auth_rule1_idx', 'auth_item', 'name', false)->execute();
