Question

我有这个代码，这段代码工作正常，数据成功存储到表＆＃34;报告＆＃34;。但我也想更新Users表及其字段Credits。我怎么能在这个功能中做到这一点？我也有这两个表格之间的关系＆＃34;报告＆＃34;和＆＃34;用户＆＃34;。

    public function giveCredits($id)
{
    $report = Report::where('id', $id)->first();
    $report->credits += Input::get('credits');
    $report->save();
    return redirect()->back();
}

用户表

Schema::create('users', function (Blueprint $table) {
    $table->increments('id');
    $table->string('name')->unique();
    $table->string('email')->unique();
    $table->string('password');
    $table->integer('credits');
    $table->enum('role', ['user', 'admin'])->default('user');
    $table->rememberToken();
    $table->timestamps();
});

报告表

    Schema::create('reports', function (Blueprint $table) {
        $table->increments('id');
        $table->integer('user_id')->unsigned();
        $table->foreign('user_id')->references('id')->on('users');
        $table->integer('credits');

您只需要添加逻辑来更新用户（假设您有一个名为user的关系方法）：

public function giveCredits($id)
{
    $report = Report::where('id', $id)->first();
    $report->credits += Input::get('credits');

    // if the report has a user, update it
    if ($report->user) {
        $report->user->credits += Input::get('credits');
        $report->user->save();
    }

    $report->save();
    return redirect()->back();
}

Laravel。使用一种POST方法
