Question

我想得到＆＃39; loan_id＆＃39;插入两个表中。

return $this->getConnection()->getPdo()->lastInsertId(); 我想我应该至少得到最后一个id（这个模型被指定为＆＃39; id＆＃39;并且自动增加）但我也没有收到它。（只是空洞的回应）

如果我可以获得插入数据库中的完整对象，那就更好了。

所以，我希望在事务失败时捕获异常并在发生故障时返回错误消息，并在成功的情况下返回$ loan_id或保存的Object。怎么做？

<?php
namespace App\model;

use Illuminate\Database\Eloquent\Model as Eloquent;
//use Illuminate\Support\Facades\DB as DB;
use Illuminate\Support\Manager as Manager;
use Illuminate\Database\Capsule\Manager as DB;
use PDO;

class Loan extends Eloquent
{
    protected $table = 'loans';

    protected $primaryKey = 'id';

    public $timestamps = false;

    public function addLoan($amount, $instalments)
    {

        // Manager::connection()->getPdo()->beginTransaction();
        $this->getConnection()->transaction(function () use ($amount)
        {
            $loan_id = substr(uniqid(), -12);

            DB::table('loans')->insert([
                    'loan_id' => $loan_id,
                    'amount' => $amount,
                    'status' => 'requested'
                ]
            );

            DB::table('loan_instalment')->insert([
                    'loan_id' => $loan_id,
                    'principal' => 777.12,
                    'interest' => 333.12
                ]
            );

        });

        return $this->getConnection()->getPdo()->lastInsertId();
    }
}
?>

Answer 1

而不是

$this->getConnection()->getPdo()->lastInsertId()

你可以这样做：

DB::table('table')->insert([...])->lastInsertId();

捕捉异常请参阅：Laravel: Using try...catch with DB::transaction()

雄辩的lastInsertId
