为什么我的异常没有被 Laravel destroy 方法捕获？

Question

为什么我的异常没有被捕获？

    try {
        \Account::destroy($id);
        return Redirect::to("/manager/account")
                            ->with("success_message", "Item excluido com sucesso");
    } catch (Exception $e) {
        return Redirect::to("/manager/account/{$id}/edit")
                        ->with("error_message", "Erro ao excluir item");
    }

SQLSTATE[23000]: Integrity constraint violation: 1451 Cannot delete or update a parent row: a foreign key constraint fails (imob_io.users, CONSTRAINT users_account_id_foreign FOREIGN KEY (account_id) REFERENCES accounts (id)) (SQL: delete from accounts where id = 2)

Answer 1

目前您正在捕获当前命名空间内的 class Exception。相反，您应该参考全局类型 \Exception:

catch (\Exception $e){
    return Redirect::to("/manager/account/{$id}/edit")
                    ->with("error_message", "Erro ao excluir item");
}

我还建议您缩小范围，而不是只捕获每个异常。例如，您可以捕获 QueryException，它将因违反约束等而被抛出。

catch(\Illuminate\Database\QueryException $e)

Why is my exception not caught by the Laravel destroy method?
