Here is how defined inside th model. The total does not return in array form after getTotalAttribute is used

protected $casts = [
    'total' => 'array'
];

public function getTotalAttribute($value)
{
    return $this->_auth($value);
}

CodePudding user response：

You have to make sure “total” in database is a valid JSON format.

The array cast is particularly useful when working with columns that are stored as serialized JSON.
