Containable to do show deeper data or join table - cakephp

Question

I have 3 tables: projects, project_reminder_users, project_types.
The relations is as follow:
Project => belong to => ProjectType
hasMany => ProjectReminderUser
ProjectReminderUser => belong to => Project
ProjectType => hasMany => Project
I get all data based on who assigned(ProjectReminderUser) by this
$this->Project->ProjectReminderUser->Behaviors->load('Containable');
$this->paginate = array(
'ProjectReminderUser' => array(
'limit' => $limit,
'contain' => array(
'Project' => array(
'ProjectComment',
'ProjectFile',
),
'User'
),
'conditions' => array(
'User.group_id' => $this->Session->read('Auth.User.group_id'),
'ProjectReminderUser.user_id' => $this->Session->read('Auth.User.id'),
'Project.project_status_id' => PROJECT_STATUS_OPEN,
),
'order' => 'Project.due_date',
)
);
$this->set('myTasks', $this->paginate('ProjectReminderUser'));
and the result look like this
array(
'ProjectReminderUser' => array(
'id' => '96',
'user_id' => '1',
'project_id' => '46'
),
'Project' => array(
'id' => '46',
'project_type_id' => '9',
'contact_id' => null,
'company_id' => null,
'subject' => 'Test Modified Field',
'description' => 'Test Modified Field',
'ProjectFile' => array(
(int) 0 => array(
'id' => '19',
'project_id' => '46',
'user_id' => '6',
'file_path' => '46_bhbinary_xmm_1728.jpg',
'notes' => null,
'created' => '2013-11-26 18:37:49'
),
),
'ProjectComment' => array(
)
),
'User' => array(
'password' => '*****',
'id' => '1',
'group_id' => '1',
'email' => 'xxx#xxxxx.com',
'first_name' => 'xxxx',
'deleted' => false,
'displayName' => 'xxxxx'
)
)
In the result There is data for Project.project_type_id, but I would like to have more detail of that. So I can show it as name instead of number. maybe like ProjectType.name instead.
How can I achieve this, so I can sort it in the view? something like this
$this->Paginator->sort('ProjectType.name', 'Type');

Answer 1

The problem is that Paginator doesn't play nice with deep model associations. I think though if rather than using Cake's methods for doing model associations, you instead do your joins manually, you may be able to work out the sorting as you want. See the below discussion.

Worst comes to worse, you may have to also rewrite the model's paginate function to deal with sorting how you need it to.

Answer 2

How about
'contain' => array(
'Project' => array(
'ProjectComment',
'ProjectFile',
'ProjectType',
),
'User'
),
Looks like you did not contain "ProjectType"
