这个很好用:

$news = NewsFeed::all();

返回是:

{
    "new": [
        {
            "id": "NF_gi042G0493C389rT1z09",
            "user_id": "CUS_G530t786S1GVwlcJ3Nw1",
            "newsfeedable_id": "STA_7F5eJ6587n2523750cZr",
            "newsfeedable_type": "Status",
            "created_at": "2015-03-31 06:01:03",
            "updated_at": "2015-03-31 06:01:03"
        },
        {
            "id": "NF_0k625I8vp9sG22637a80",
            "user_id": "CUS_G530t786S1GVwlcJ3Nw1",
            "newsfeedable_id": "CNT_dF22v8dorG2k143N1288",
            "newsfeedable_type": "Contact",
            "created_at": "2015-03-30 10:04:34",
            "updated_at": "2015-03-30 10:04:34"
        }
    ]
}

==============

但是这个:

$news = DB::select( DB::raw(" SELECT * FROM `news_feed` ") );

注意:mysql查询很好,工作正常

我的代码:

$x = $news->updated_at->diffForHumans();
echo $x;

错误:

  

在非对象

上调用成员函数diffForHumans()

我这里做的var_dump是db raw:

的结果
{
      "new": [
            {
                "id": "NF_gi042G0493C389rT1z09",
                "user_id": "CUS_G530t786S1GVwlcJ3Nw1",
                "newsfeedable_id": "STA_7F5eJ6587n2523750cZr",
                "newsfeedable_type": "Status",
                "created_at": "2015-03-31 06:01:03",
                "updated_at": "2015-03-31 06:01:03"
            },
            {
                "id": "NF_0k625I8vp9sG22637a80",
                "user_id": "CUS_G530t786S1GVwlcJ3Nw1",
                "newsfeedable_id": "CNT_dF22v8dorG2k143N1288",
                "newsfeedable_type": "Contact",
                "created_at": "2015-03-30 10:04:34",
                "updated_at": "2015-03-30 10:04:34"
            }
        ]
}

Eloquent和DB raw var dump结果是100%相同。

为什么diffForHumans()不能在db raw上工作?

1 个答案:

答案 0 :(得分:0)

如果你尝试使用eloquent

var_dump updated_at

的var_dump($ eloquent_news->的updated_at);

{
        "date": "2015-03-31 06:01:03.000000",
        "timezone_type": 3,
        "timezone": "UTC"
    }

这是由讽刺作者更新的update_at的实际结果,我不知道如何在DB :: raw中发生这种情况。但至少你现在知道发生了什么。

<强>底线:

  

Eloquent updated_at和DB :: raw不是100%相同。
