Laravel 在没有明确调用的情况下更新时间戳

Laravel Timestamp Being Updated Without Explicit Call To Do So

所以我 运行 遇到了 Laravel 更新和保存的恼人问题。我有一个 model/table Invoiceinvoices,它们有一个时间戳 sent_at

Invoice.php

class Invoice extends Model {
    protected $dates = [
        "sent_at",
    ];
}

我有以下更新 Invoice 的函数:

InvoicesController.php:

public function postPayInvoice(Request $request, $invoiceId){
    $user = $this->apiResponse->user;

    $invoiceItemIds = $request->input("invoice_item_ids");

    $invoice = Invoice::with(["invoiceItems" => function($subQuery) use($invoiceItemIds){
        return $subQuery->whereIn("invoice_items.id", $invoiceItemIds);
    }])->where("id", "=", $invoiceId)->first();

    \Log::info("Load: ".$invoice->sent_at);

    DB::beginTransaction();
    try {
        foreach($invoice->invoiceItems AS $invoiceItem){
            $invoiceItem->status = "paid";
            $invoiceItem->paid_at = Carbon::now();
            $invoiceItem->save();
        }

        $totalInvoices = $invoice->invoiceItems()->count();
        $paidInvoiceItems = $invoice->invoiceItems()->where("status", "=", "paid")->count();

        if($totalInvoices == $paidInvoiceItems){
            $invoice->status = "paid";
            $invoice->paid_at = Carbon::now();
        } else {
            $invoice->status = "partially_paid";
        }

        \Log::info("Pre: ".$invoice->sent_at);

        $invoice->save();

        \Log::info("Post: ".$invoice->sent_at);

    } catch(\Exception $ex){
        DB::rollBack();
        return $this->apiResponse->returnFail([], "Unable to Pay Invoice: ".$ex->getMessage(), 200);
    }

    DB::{$request->input("rollback", null) ? "rollback" : "commit"}();

    \Log::info("Post Commit: ".$invoice->sent_at);

    return $this->apiResponse->returnSuccess($invoice, "Invoice paid!", 200);
}

这样做是支付选定的 InvoiceItemsInvoice 的子模型),并且,如果所有 InvoiceItems 都标记为 paid,则更新 invoices.statuspaid(或partially_paid)和invoices.paid_atCarbon::now()(或null)。

一切正常,但不知何故,这段代码也在更新 sent_at(因此 \Log 语句)。当代码加载 Invoice 时,在应用所有保存逻辑之后,在保存之后,最后在提交之后,记录了 sent_at 属性:

[2019-05-08 12:43:24] local.INFO: Load: 2019-05-08 12:42:50
[2019-05-08 12:43:24] local.INFO: Pre: 2019-05-08 12:42:50
[2019-05-08 12:43:24] local.INFO: Post: 2019-05-08 12:42:50
[2019-05-08 12:43:24] local.INFO: Post Commit: 2019-05-08 12:42:50

如您所见,sent_at 时间戳始终是 2019-05-08 12:42:50。但是我一重新查询数据库,时间戳是2019-05-08 12:43:24,这是paid_atupdated_at时间戳的值。

(status, sent_at, paid_at, created_at, updated_at)

请注意,这是从 API 调用的,随后请求加载 Invoice 模型列表,它具有以下逻辑来确定附加逻辑:

$cutoff = $this->sent_at->addDays(3)->endOfDay();

但我看不出如何修改 sent_at 列(后面没有调用 save/update,即使调用了,2019-05-08 12:43:24 也不等同于 addDays(3)->endOfDay();

有人以前看过这个吗?它在另一个视图中弄乱了一些排序逻辑,所以我最终需要修复它...

编辑

如果我禁用 $invoice->save();,它的 updated_at 时间戳仍然会更新,但我不知道为什么。而且,奇怪的是,禁用 $invoiceTransaction->save();$invoiceItem->save(); 不会导致 updated_at 发生任何变化...确实会导致数据错误,但这仍在开发中。

二次编辑

"CREATE TABLE `invoices` (
`id` int(10) unsigned NOT NULL AUTO_INCREMENT,
`user_id` int(11) NOT NULL,
`account_id` int(11) NOT NULL,
`description` text,
`subtotal` decimal(10,2) NOT NULL,
`grand_total` decimal(10,2) NOT NULL,
`status` enum('pending','sent','partially_paid','paid') NOT NULL DEFAULT 
'pending',
`sent_at` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
`paid_at` timestamp NULL DEFAULT NULL,
`created_at` timestamp NULL DEFAULT NULL,
`updated_at` timestamp NULL DEFAULT NULL,
`deleted_at` timestamp NULL DEFAULT NULL,
PRIMARY KEY (`id`)
)
ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8"

我认为这里有问题:

sent_at timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,

这是由于 MySQL 5.7 配置,而不是 Laravel。

The first TIMESTAMP column in a table, if not explicitly declared with the NULL attribute or an explicit DEFAULT or ON UPDATE attribute, is automatically declared with the DEFAULT CURRENT_TIMESTAMP and ON UPDATE CURRENT_TIMESTAMP attributes.

修复方法是在迁移中将时间戳设置为可为空,and/or手动更改 table。

ALTER TABLE invoices CHANGE sent_at sent_at timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP;
