When I'm trying to eager load my Model with relation like that:

$plants = Plant::with('history')
    ->get()
    ->where('user_id', auth()->id());

I want to modify those extracted dates with my function like that:

foreach ($plants as $plant) {
        $plant->watered_at = self::getDateForHumans($plant->history->watered_at);
        $plant->fertilized_at = self::getDateForHumans($plant->history->fertilized_at);
    }

I get this kind of error:

ErrorException Trying to get property 'watered_at' of non-object

but if I try to debug it by dd() function i get a positive result

   dd(self::getDateForHumans($plant->history->watered_at));

dd() result

Does anybody know how to fix it or what is the workaround?

CodePudding user response：

seems your history has no watered_at member, so it comes to this error.

Check first if you can access this member with

if(isset($plant->history->watered_at)){
    $plant->watered_at = self::getDateForHumans($plant->history->watered_at);
}
