Question

我的代码有问题。我必须使用5个表中的id删除数据，这些表由主键和外键连接。

这是我尝试过的方法，但是它将显示添加订阅表ID。但是已经添加了订阅表ID。

$subscription = DB::table('tbl_asset_subscription')->where('id',$post['asset_id'])->get();
        foreach($subscription as $row)
        {
        DB::table('tbl_asset_subscription')->where('id',$row->id)->delete();
        }

        $orderId = array();

        foreach($subscription as $row)
        {
        $order = DB::table('tbl_asset_order')->where('subscription_id',$row->id)->first();
        $orderId[] = $order->id;

        }


        foreach($orderId as $row)
        {
        DB::table('tbl_asset_payment')->where('order_id',$row->id)->delete();
        DB::table('tbl_asset_order')->where('id',$row->id)->delete();
        }





        DB::table('tbl_asset_versions')->where('asset_id',$post['asset_id'])->delete();
        DB::table('tbl_assets')->where('id',$post['asset_id'])->delete();

        // DB::table('tbl_asset_subscription')->where('asset_id',$post['asset_id'])->delete();
        echo(json_encode(array("result" => true)));

{
    "message": "SQLSTATE[23000]: Integrity constraint violation: 1451 Cannot delete or update a parent row: a foreign key constraint fails (`piccoscript`.`tbl_asset_subscription`, CONSTRAINT `fk_tbl_asset_subscription_tbl_assets` FOREIGN KEY (`asset_id`) REFERENCES `tbl_assets` (`id`) ON DELETE NO ACTION ON UPDATE NO ACTION) (SQL: delete from `tbl_assets` where `id` = 1)",

Answer 1

您可以暂时禁用外键约束

在Laravel中，您可以执行以下操作：

import {MyClass} from './MyClass'
describe('Test the MyClass:', () => {
    test('invalid inputs for thefunction()',  () => {
        expect(MyClass.theFunction(0)).toThrow(/*'TypeError: tokens is not iterable'*/); 
        //Tried with and without the Error Message
    });
});

Answer 2

$ orderId不是关联数组，因此出现错误。试试这个代码。

foreach($subscription as $row)
{
$order = DB::table('tbl_asset_order')->where('subscription_id',$row->id)->first();
$orderId[] = array(
        'id' => $order->id
    );

}


foreach($orderId as $row)
{
DB::table('tbl_asset_payment')->where('order_id',$row->id)->delete();
DB::table('tbl_asset_order')->where('id',$row->id)->delete();
}


DB::table('tbl_asset_versions')->where('asset_id',$post['asset_id'])->delete();
DB::table('tbl_assets')->where('id',$post['asset_id'])->delete();

// DB::table('tbl_asset_subscription')->where('asset_id',$post['asset_id'])->delete();
echo(json_encode(array("result" => true)));

加入所有表时删除多个表中的数据php larvel
