問題描述

它非常簡單，因為它是最基本的東西，但我不知道我錯過了什么:

It's pretty straightforward as it's the most basic thing but I don't know what I'm missing:

有一個名為 Site

我正在使用 Eloquent ORM，所以當我調用(在控制器中)

I'm using Eloquent ORM, so when I call (in a controller)

$oSite = Site::find(1)

然后

var_dump($oSite);

它返回一個 NULL 的值.

但是當我檢查數據庫時，表sites"實際上包含以下項目:

But when I check the database, the table 'sites' actually contains the following item:

id: 1
user_id: 1
name: test

在我的 Site model 中，我有以下代碼:

In my Site model I have the following code:

use IlluminateDatabaseEloquentModelNotFoundException;

 Class Site extends Eloquent {

        protected $table = 'sites';

        protected $fillable = ['user_id', 'name'];
 }

相反，如果我使用以下內容收集項目:

Instead, if I gather the item with the following:

$oSite = DB::table('sites')
                ->where('id', 1)
                ->first();

它有效并且我得到了正確的寄存器.

It works and I get the correct register.

我做錯了什么?我沒有得到文檔的哪一部分?

What I'm doing wrong? Which part of the documentation I didn't get?

型號代碼可以在上面查看.

Model code can be checked above.

控制器:

use IlluminateSupportFacadesRedirect;
class SiteManagementController extends BaseController {

...

    public function deleteSite()
    {
        if (Request::ajax())
        {
            $iSiteToDelete = Input::get('siteId');

            $oSite = Site::find($iSiteToDelete);

            return var_dump($oSite);
        }
        else
        {
            return false;
        }
    }
}

編輯 2:(已解決)

不工作的真正原因:

我的模型代碼原本如下:

use IlluminateDatabaseEloquentSoftDeletingTrait;
use IlluminateDatabaseEloquentModelNotFoundException;

Class Site extends Eloquent {

    protected $table = 'sites';

    use SoftDeletingTrait;

    protected $dates = ['deleted_at'];

    protected $fillable = ['user_id', 'name'];
}

問題是我在啟動項目后添加了一個deleted_at"列，當我應用遷移時，我沒有啟用軟刪除.顯然，我犯了第二個錯誤，忘記啟用 'deleted_at' 為可空，因此所有插入的時間戳都錯誤(0000-00-00 ...).

Problem was I added a 'deleted_at' column after I started the project and when I applied migrations, I didn't have softdeleting enabled. Obviously, I did a second error, forgetting to enable 'deleted_at' to be nullable, hence all inserts went had a wrong timestamp (0000-00-00 ...).

修復:

1. 使deleted_at"列可以為空.

將所有錯誤的 'deleted_at' 時間戳設置為 NULL.

Set all wrong 'deleted_at' timestamps to NULL.

推薦答案

檢查您是否正確獲取了 Input::get('siteId').如果您得到它，請嘗試將其轉換為整數，即

Check you are getting Input::get('siteId') correctly. if you are getting it then try to convert it into integer i.e

$iSiteToDelete = intval(Input::get('siteId'));
