Question

当你从模型中的数据库中检索数据时，将所有值都返回为字符串。

例如，如果您加载模型$ user = User :: findFirst（1），当您访问属性$ user-＆gt; id时，它返回一个（字符串）“1”。

我在模型中声明元数据以尝试获取php类型，但不起作用：

public function metaData()
{
    return array(
        //Every column in the mapped table
        MetaData::MODELS_ATTRIBUTES => array(
            'id',  'email', 'password', 'created'
        ),

        //Every column part of the primary key
        MetaData::MODELS_PRIMARY_KEY => array(
            'id'
        ),

        //Every column that isn't part of the primary key
        MetaData::MODELS_NON_PRIMARY_KEY => array(
             'email', 'password', 'created'
        ),

        //Every column that doesn't allows null values
        MetaData::MODELS_NOT_NULL => array(
            'id',  'email', 'password', 'created'
        ),

        //Every column and their data types
        MetaData::MODELS_DATA_TYPES => array(
            'id' => Column::TYPE_INTEGER,
            'email' => Column::TYPE_VARCHAR,
            'password' => Column::TYPE_VARCHAR,
            'created' => Column::TYPE_INTEGER,
        ),

        //The columns that have numeric data types
        MetaData::MODELS_DATA_TYPES_NUMERIC => array(
            'id' => true,
            'year' => true,
        ),

        //The identity column, use boolean false if the model doesn't have
        //an identity column
        MetaData::MODELS_IDENTITY_COLUMN => 'id',

        //How every column must be bound/casted
        MetaData::MODELS_DATA_TYPES_BIND => array(
            'id' => Column::BIND_PARAM_INT,
            'email' => Column::BIND_PARAM_STR,
            'password' => Column::BIND_PARAM_STR,
            'created' => Column::BIND_PARAM_INT,
        ),

        //Fields that must be ignored from INSERT SQL statements
        MetaData::MODELS_AUTOMATIC_DEFAULT_INSERT => array(
            'id' => true
        ),
    );
}

Phalcon有办法将sql类型自动转换为php类型吗？感谢。

Answer 1

如果您使用Phalcon \ Db \ Adapter \ Pdo \ Mysql作为适配器，默认情况下整数将作为字符串在PDO中返回

返回正确的类型，您需要为适配器设置适当的选项，你需要设置 ATTR_EMULATE_PREPARES和ATTR_STRINGIFY_FETCHES到false

您需要在配置或服务文件中更改您的适配器代码，如此设置

return new Phalcon\Db\Adapter\Pdo\Mysql([
    'host' => 'DATABASE_HOST',
    'username' => 'USERNAME',
    'password' => 'PASSWORD',
    'dbname' => 'DATABASE_NAME',
    'options' => array(
        PDO::ATTR_EMULATE_PREPARES => false,
        PDO::ATTR_STRINGIFY_FETCHES => false,
    )
]);

Answer 2

重要的是要说你需要原生的mysql驱动程序。否则选项不会影响。

sudo apt-get purge php5-mysql
sudo apt-get install php5-mysqlnd

sql数据类型为模型中的php数据类型
