如何在特定字段之前的exisitng MongoDB集合文档中添加两个新字段？

Question

我正在使用Laravel Jensegger's Moloquent库来使用Mongo DB。我有一个像这样的Mongo DB文档： -

{
    "_id" : ObjectId("5b1e05d7987a8e0bcd018966"),
    "place_id" : "5a29f3d8d4cc987f64976fc9",
    "title_AR" : "Kick Axe",
    "title_EN" : "Kick Axe",
    "description_AR" : "",
    "description_EN" : "",
    "best_photo" : "https://igx.4sqi.net/img/general/250x250/65688_HR7zrFOF5fpgVEB8Nv9SBxoy2YgZm65K36-mvoHmzWg.jpg",
    "city_AR" : "New York",
    "city_EN" : "New York",
    "state_AR" : "NY",
    "state_EN" : "NY",
    "country" : "US",
    "postal_code_AR" : "11217",
    "postal_code_EN" : "11217",
    "location_AR" : "622 Degraw St, New York, NY 11217, United States",
    "location_EN" : "622 Degraw St, New York, NY 11217, United States",
    "latitude" : 40.6790636331833,
    "longitude" : -73.9835408883314,
    "loc" : {
        "type" : "Point",
        "coordinates" : [ 
            -73.9835408883314, 
            40.6790636331833
        ]
    },
    "website" : "https://www.kickaxe.com",
    "email" : "",
    "contact_number_AR" : "8335425293",
    "contact_number_EN" : "8335425293",
    "ratings_AR" : "8.7",
    "ratings_EN" : "8.7",
    "no_of_comments_AR" : 8,
    "no_of_comments_EN" : 8,
    "categories" : "4d4b7105d754a06377d81259,5744ccdfe4b0c0459246b4b5,4d4b7105d754a06377d81259,5744ccdfe4b0c0459246b4b5,4d4b7104d754a06370d81259,4bf58dd8d48988d1f1931735,4d4b7105d754a06377d81259,4eb1d4d54b900d56c88a45fc",
    "category_array" : [ 
        "4d4b7105d754a06377d81259", 
        "5744ccdfe4b0c0459246b4b5", 
        "4d4b7105d754a06377d81259", 
        "5744ccdfe4b0c0459246b4b5", 
        "4d4b7104d754a06370d81259", 
        "4bf58dd8d48988d1f1931735", 
        "4d4b7105d754a06377d81259", 
        "4eb1d4d54b900d56c88a45fc"
    ],
    "created_date" : "2018-06-11 10:47:11",
    "modified_date" : "2018-06-11 10:47:11",
    "photo_saved" : 0,
    "tip_saved" : 0,
    "updated_at" : ISODate("2018-06-11T05:17:11.000Z"),
    "created_at" : ISODate("2018-06-11T05:17:11.000Z")
}

该文档没有任何名为“ complete_status ”和“ cannonical_url ”的字段。

我想在现有文档中添加这两个字段。我正在使用此代码： -

$insertUrl = MongoFourSquarePlaces::where('place_id',$place_id)
                                ->update(
                                        array(
                                            'cannonical_url'=> $url, 
                                           'complete_status'=>1
                                        ));

此代码在“ created_at ”之后添加了两个字段＆amp; “ updated_at ”字段。如何在所需位置添加两个新字段，例如在“ created_at ”字段之前？
