cakephp formatting an array - php

Question

My goal is to display 1 Projects and many Keywords to it. My DB is simple:
Project has many Keywords
Keyword belongs to Project
So far so good. Now I try to get the Information in my ProjectsController:
public function view($id = null)
{
$this->Project->bindModel(array('hasMany' => array('Keyword' => array('className' => 'Keyword',
'foreignKey' => 'project_id')
)), false);
$this->paginate['Project']['conditions'] = array('Project.id' => $id);
$this->paginate['recursive'] = '2';
$this->set('projects', $this->paginate('Project'));
$Projects = $this->paginate('Project');
$this->set('projects', $this->paginate());
}
by printing out the array it looks a bit unexpected:
Array
(
[0] => Array
(
[Project] => Array
(
[id] => 3
[title] => Foo
[created] => 2013-08-05 17:39:07
[modified] => 2013-08-05 17:39:07
)
[Keyword] => Array
(
[0] => Array
(
[id] => 1
[project_id] => 3
[title] => Num1
[demand] => 50000000000
[competition] => 37889.56700
[cpc] => 676.50
[created] => 2013-06-26 17:54:48
[modified] => 2013-09-19 13:37:25
)
)
)
[1] => Array
(
[Project] => Array
(
[id] => 4
[title] => Bar
[created] => 2013-08-05 17:39:07
[modified] => 2013-08-05 17:39:07
)
[Keyword] => Array
(
[0] => Array
(
[id] => 3
[project_id] => 4
[title] => Num1
[demand] => 76534000000
[competition] => 5555.55560
[cpc] => 99.34
[created] => 2013-06-26 17:54:48
[modified] => 2013-09-19 13:37:36
)
)
)
)
Now I have the problem, how do i display it with the right Project.id? because the new created array contains a different id than Project.id. My question is how do I filter the right Project.id for display it only in my /View/[id]
EDIT
I think the best way to work with, is an array structure like this:
Array
(
[Project] => Array
(
[id] => 3
[title] => Lerncoachies
[created] => 0000-00-00 00:00:00
[modified] => 2013-08-05 17:39:07
)
[Keyword] => Array
(
[0] => Array
(
[id] => 1
[project_id] => 3
[title] => Num1
[demand] => 50000000000
[competition] => 37889.56700
[cpc] => 676.50
[created] => 2013-06-26 17:54:48
[modified] => 2013-09-19 13:37:25
)
)
)
)

Answer 1

From descriptions it looks like you'd like to paginate Keywords not Projects - so you have 'unexpected result'.
This is an expected result for paginating Projects.
If you'd like to paginate Keywords then:
$this->Project->recursive = 1;
$project = $this->Project->findById($id);
$this->loadModel('Keywords'); // I don't remember if this is needed
$this->paginate['Keywords'] = array(
'project_id' => $project['Project']['id']
);
$this->set('keywords', $this->paginate('Keyword'));
$this->set('project', $project);
You'll have a view with 1 Project and you'll be able to paginate Keywords related to given project with sorting.

Answer 2

public function view($id = null) {
$this->Project->bindModel(array(
'hasMany' => array('Keyword' => array(
'className' => 'Keyword',
'foreignKey' => 'project_id')
)), false
);
$this->Project->recursive = 2;
$project = $this->Project->findById($id);
}
Now your project array should suffice your requirement.
