使用Phalcon开发工具碰到的数据库问题"Table 'XXX' doesn't exist in database when dumping meta-data for XXX"

使用Phalcon开发工具，通过命令行生成程序框架

设置好config.php，在对数据库进行读取、保存数据的时候出现了问题“Table 'XXX' doesn't exist in database when dumping meta-data for XXX”

注意到上方还有一条语句“Array to string conversion”，找到对应services.php处的代码

 $di->set('db', function () use ($config) {
     return new DbAdapter($config->toArray());
 });

再查看$config内容

$config = include __DIR__ . "/../app/config/config.php";

config.php内容

 <?php

 return new \Phalcon\Config(array(
     'database' => array(
         'adapter'     => 'Mysql',
         'host'        => 'localhost',
         'username'    => 'root',
         'password'    => '',
         'dbname'      => 'eduhelper',
         'charset'     => 'utf8',
     ),
     'application' => array(
         'controllersDir' => __DIR__ . '/../../app/controllers/',
         'modelsDir'      => __DIR__ . '/../../app/models/',
         'migrationsDir'  => __DIR__ . '/../../app/migrations/',
         'viewsDir'       => __DIR__ . '/../../app/views/',
         'pluginsDir'     => __DIR__ . '/../../app/plugins/',
         'libraryDir'     => __DIR__ . '/../../app/library/',
         'cacheDir'       => __DIR__ . '/../../app/cache/',
         'baseUri'        => '/eduHelper/',
     )
 ));

经分析是数据库连接那块出了问题，可以看到$config中还有一个'application'，而我们所需要的显然只有'database'

应该将services.php处的代码改为

 $di->set('db', function () use ($config) {
     return new DbAdapter($config->database->toArray());
 });

或者

$di->set('db', function () use ($config) {
    return new DbAdapter($config['database']->toArray());
});
