我刚刚将Laravel的数据库层Eloquent包含在我的CodeIgniter 3项目中。然而,我的问题是我无法使用Eloquent模型连接到多个数据库。
对于默认数据库,这是我配置数据库的方式:
$capsule = new Capsule;
$capsule->addConnection(array(
'driver' => 'mysql',
'host' => "localhost",
'database' => "employees_db",
'username' => "root",
'password' => "",
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
));
$capsule->setAsGlobal();
$capsule->bootEloquent();
以上效果很好。但我有一个来自另一个数据库的员工表。我可以使用查询构建器来使用它,但是使用Eloquent模型会失败。
我试过了:
$employees = new Capsule;
$employees->addConnection(array(
'driver' => 'mysql',
'host' => "host2",
'database' => "employees_db",
'username' => "user",
'password' => "pass",
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
),'employees');
$employees->setAsGlobal();
尝试设置Eloquent模型并使用如下连接:
protected $connection = "employees";
是否可以使用Laravel之外的Illuminate \ Database Eloquent ORM连接到多个数据库?如果是,怎么样?
答案 0 :(得分:14)
雄辩的ORM只需要初始化一次。添加可选的第二个参数作为连接名称。
$capsule = new Capsule;
$capsule->addConnection(
array(
'driver' => 'mysql',
'host' => "localhost",
'database' => "employees_db",
'username' => "root",
'password' => "",
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
),
"default"
);
$capsule->addConnection(
array(
'driver' => 'mysql',
'host' => "192.168.1.1",
'database' => "employees_db2",
'username' => "user",
'password' => "password",
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
),
"employees"
);
$capsule->setAsGlobal();
$capsule->bootEloquent();
如果已经设置了上述内容,您可以通过编写以下代码来指定模型文件中要连接的数据库:
protected $connection = "employees";
