打开/config/db.php
return [
'class' => 'yii\db\Connection',
'dsn' => 'mysql:host=localhost;dbname=yii2basic',
'username' => 'root',
'password' => '',
'charset' => 'utf8',
// Schema cache options (for production environment)
//'enableSchemaCache' => true,
//'schemaCacheDuration' => 60,
//'schemaCache' => 'cache',
];
把配置改为
return [
'db' => [
'class' => 'yii\db\Connection',
'dsn' => 'mysql:host=localhost;dbname=yii2basic',
'username' => 'root',
'password' => '',
'charset' => 'utf8',
],
// Schema cache options (for production environment)
//'enableSchemaCache' => true,
//'schemaCacheDuration' => 60,
//'schemaCache' => 'cache',
];
然后报错
打开/config/web.php
加上 $config['components'] = array_merge($config['components'], $db);
