问题描述

所以我遇到了 Laravel 更新和保存的烦人问题.我有一个模型/表 Invoiceinvoices,它有一个时间戳 sent_at.

So I'm running into an annoying problem with Laravel update and save. I have a model/table Invoice and invoices, that has a timestamp 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InvoiceItems(Invoice 的子模型),并且,如果所有InvoiceItems 都被标记为支付,然后将invoices.status 更新为paid(或partially_paid)并将invoices.paid_at 更新为Carbon::now()(或null).

What this does is pays the selected InvoiceItems (child model of Invoice), and, if all InvoiceItems are marked as paid, then updates invoices.status to paid (or partially_paid) and invoices.paid_at to Carbon::now() (or null).

这一切正常,但不知何故,这段代码也在更新 sent_at(因此是 Log 语句).当代码加载 Invoice 时,在应用所有保存逻辑后,在保存后,最后在提交后,记录 sent_at 属性:

This all works fine, but somehow, this code is also updating sent_at (hence the Log statements). When the code loads the Invoice, after applying all save logic, right after saving and finally right after committing, the sent_at attribute is logged:

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

[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 时间戳始终为 2019-05-08 12:42:50.但是我一重新查询数据库,时间戳就是2019-05-08 12:43:24,也就是paid_at的值updated_at 时间戳.

As you can see, the sent_at timestamp is consistently 2019-05-08 12:42:50. But as soon as I re-query the database, the timestamp is 2019-05-08 12:43:24, which is the value of the paid_at and updated_at timestamps.

(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,该模型具有以下逻辑来确定附加逻辑:

Note this is called from an API, with a subsequent request to load a list of Invoice models, which has the following logic to determine so additional logic:

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

但我看不出这如何修改 sent_at 列(以下不会调用保存/更新,即使调用了,2019-05-08 12:43:24 不等于 addDays(3)->endOfDay();

But I don't see how that could modify the sent_at column (no save/update is called following, and even if it did, 2019-05-08 12:43:24 does not equate to addDays(3)->endOfDay();

有人见过这个吗?它在另一个视图中搞乱了一些排序逻辑,所以我最终需要修复它......

Has anyone seen this before? It's messing up some ordering logic in another view, so I need to fix it eventually...

编辑

如果我禁用 $invoice->save();,它的 updated_at 时间戳仍然更新,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...确实会导致错误的数据,但仍在开发中.

If I disable $invoice->save();, it's updated_at timestamp is still updated, but I have no idea why. And, oddly enough, disabling $invoiceTransaction->save(); and $invoiceItem->save(); results in no change to updated_at... Does result in bad data, but this is still in development.

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"

我认为那里存在问题:

sent_at 时间戳 NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,

sent_at timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,

推荐答案

这是由于 MySQL 5.7 配置,而不是 Laravel.

This is due to the MySQL 5.7 configuration, and not Laravel.

表中的第一个 TIMESTAMP 列,如果未使用 NULL 属性或显式 DEFAULT 或 ON UPDATE 属性显式声明,将自动使用 DEFAULT CURRENT_TIMESTAMP 和 ON UPDATE CURRENT_TIMESTAMP 属性声明.

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.

src - Mysql 文档

修复方法是在迁移中将时间戳设置为可为空,和/或手动更改表.

The fix is to set the timestamp to nullable in the migration, and/or alter the table manually.

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