Question

users表包含一个items数组，它只是Item ObjectId的集合。

用户

<?php
include_once 'dbconfig.php';
$first_name= null;
$last_name=null;
$employee_nrc=null;
$phone_no=null;
$business_type=null;
$business_site=null;
$business_activity=null;

if(isset($_POST['btn-update']))
{
    $id = $_POST['edit_id'];
    $fname = $_POST['first_name'];
    $lname = $_POST['last_name'];
    $employee_nrc = $_POST['employee_nrc'];
    $Phone = $_POST['phone_no'];
    $Businesstype = $_POST['business_type'];
    $Businesssite = $_POST['business_site'];
    $Businessactivity = $_POST['business_activity'];


    if($crud->update($id,$fname,$lname,$employee_nrc,$Phone,$Businesstype,$Businesssite,$Businessactivity))
    {
        $msg = "<div class='alert alert-info'>
                <strong>WOW!</strong> Record was updated successfully <a href='index.php'>HOME</a>!
                </div>";
    }
    else
    {
        $msg = "<div class='alert alert-warning'>
                <strong>SORRY!</strong> ERROR while updating record !
                </div>";
    }
}

if(isset($_GET['edit_id']))
{
    $id = $_GET['edit_id'];
    extract($crud->getID($id));

项

{
  state: 'active',
  items: [ObjectId("4ecc05e55dd98a436ddcc47c"), ObjectId("4ecc05e55dd98a436ddcc47d")]
}

我想编写一个查询，查找所有拥有带创建者＆＃39;标记＆＃39;的项目的用户。这可能在一个查询中？我试过这样的东西，但它不起作用。

{
 name: 'weapon',
 creator: 'mark'
}

Answer 1

首先，您需要将项目集合作为嵌入或引用。考虑到这种结构，我们可以将查询编写为

db.Users.find（{“items.creator”：'mark'}）

使用mongoose查询ObjectIds数组
