CakePHP 3 paginate order by ambigious column bug?

Question

Когда im пытается передать условие подходящей функции, сопоставляя задачи с проектами, paginator передает ORDER BY, удаляя объект Table и заставляя столбец быть неоднозначным.

Это ошибка или кто-нибудь знает, как это могло случиться?

MATCHING

if($groupFilter) 
{ 
    // Filtering by group 
    $projects = $this->Projects->find('all')->where($wheres) 
     ->matching('Tasks', function ($q) use ($groupFilter) { 
      return $q->where(['Tasks.group_id' => $groupFilter, 'Tasks.removed' => 0])->order(['Tasks.deadline ASC', 'Tasks.created ASC']); 
       }) 
     ->contain(['Customers','Tasks.Users'])->distinct(['Projects.id']); 
} 
else 
{ 
    // Groupfiltering is not set, filter normally. 
    $projects = $this->Projects->find('all')->contain(['Customers'])->where($wheres)->contain([ 
     'Tasks', 
     'Tasks.Users' 
    ]); 
} 

постраничной

$this->paginate = [ 
    'sortWhitelist' => [ 
      'Projects.name', 'Customers.name', 'Projects.deadline IS NULL', 'Projects.tasks_active', 'Projects.tasks_used_hours', 'Projects.deadline' 
    ], 
    'order' => [ 
     'Projects.deadline IS NULL' => 'ASC', 
     'Projects.deadline' => 'ASC' 
    ], 
    'limit' => 50 
]; 
$this->set('projects', $this->paginate($projects));

Такие ключи порядка не supporte d, механизм префиксации paginators наткнется на него, так как он ожидает синтаксис Alias.field, и существование полей будет проверено на схеме модели.

Для того, чтобы иметь возможность использовать такие пункты заказа, вы должны будете применять их с помощью объекта запроса вместо. Следовательно, вы не можете сортировать пользователя по такой статье из коробки, вам нужно будет реализовать механизм, который захватывает (и выводит) значение sort из запроса запроса и применяет его к запросу, например

$sort = $this->request->query('sort'); 
// you may want to choose a non-technical alias instead 
if ($sort !== null && $sort === 'Projects.deadline IS NULL') { 
    unset($this->request->query['sort']); 

    $expression = $projects->newExpr()->isNull('Projects.deadline'); 
    if (strtoupper($this->request->query('direction')) === 'ASC') { 
     $projects->orderAsc($expression); 
    } else { 
     $projects->orderDesc($expression); 
    } 
}
