[英]Return _data array from ORM with FuelPHP
我正在使用FuelPHP及其ORM創建REST API,文檔可在此處找到: http ://fuelphp.com/docs/packages/orm/crud.html
我可以像這樣返回數據庫行的對象:
$entry = Model_V1_Inventory::find(1);
這使我返回了PK等於1的對象,這與預期的一樣。 如何訪問_data數組以json_encode並將其作為REST響應的一部分返回? 我可以通過簡單地調用以下命令來訪問數組中的單個項目:
$entry->product_ref
作為示例,但無論如何我都看不到返回受保護的_data數組。
從ORM返回的對象:
Model_V1_Inventory Object
(
[_is_new:protected] =>
[_frozen:protected] =>
[_sanitization_enabled:protected] =>
[_data:protected] => Array
(
[product_ref] => from the model
[cost_price] => 0.99
[rrp_price] => 11.67
[current_price] => 5.47
[description] => test description
[created_at] => 2016-04-26 14:29:20
[updated_at] => 2016-04-26 14:29:20
[id] => 1
)
[_custom_data:protected] => Array
(
)
[_original:protected] => Array
(
[product_ref] => from the model
[cost_price] => 0.99
[rrp_price] => 11.67
[current_price] => 5.47
[description] => test description
[created_at] => 2016-04-26 14:29:20
[updated_at] => 2016-04-26 14:29:20
[id] => 1
)
[_data_relations:protected] => Array
(
)
[_original_relations:protected] => Array
(
)
[_reset_relations:protected] => Array
(
)
[_disabled_events:protected] => Array
(
)
[_view:protected] =>
[_iterable:protected] => Array
(
)
)
好了,在玩了一些游戲之后,我發現使用FuelPHP的一個內置類Format來解決此問題。
Format::forge($entry)->to_array();
將執行轉換,然后對響應數組進行json_encode編碼。 這是我使用FuelPHP ORM將json編碼的字符串發送回用戶的完整方法:
public function get_product()
{
$product_id = Uri::segment(4);
$response = new Response();
try{
if($product_id == null){
throw new Exception('No product ID given');
}else{
$entry = Model_V1_Inventory::find($product_id);
$entry = Format::forge($entry)->to_array();
$response->body(json_encode($entry));
$response->set_status(200);
return $response;
}
}catch(Exception $e){
$response->body(json_encode(['Status' => 400, 'Message' => $e->getMessage()]));
$response->set_status(400);
return $response;
throw new Exception($e);
}
}
您也可以簡單地使用$entry->to_array()
,不需要Format
類。
