解析：在查询<PHP>中包含相关对象

I have _Installation and Swipt_User classes in parse, the installation has UserR, which related to Swipt_User table as in the pic :

I have this query :

$query = new ParseQuery("_Installation");
$query->includeKey("Swipt_User");
$installations = $query->find(true);

included the object related to installation which is Swipt_User, but when i try to get the object in foreach, it didn't get it as below and returned as null

foreach ($installations as $key => $installation) {
    $user = $installation->get('Swipt_User');
}

Any help ? .. please

You need to specify the name of the column, not the name of the related table (group), when using include.

Your code needs to be:

$query = new ParseQuery("_Installation");
$query->includeKey("userR");
$installations = $query->find(true);
