Saving data with 2 HABTM and one hasMany association - cakephp

Question

I am trying to save data with multiple HABTM & hasMany relation. Even if I use
$this->Project->save();
$this->Project->saveMany();
$this->Project->saveAssociated();
$this->Project->saveAlll();
It does not save associated model, I can't figure out what I am doing wrong.
Models Reations
Project hasAndBelongsToMany Skill
Project hasMany Milestone
Project hasAndBelongsToMany Attachment (because Milestone's will also have attachement so can not bind project & attachment in hasMany Relation)
Project Model
class Project extends AppModel{
public $belongsTo = array('Profile');
public $hasMany = array('Milestone');
public $hasAndBelongsToMany = array(
'Skill' =>
array(
'className' => 'Skill',
'joinTable' => 'projects_skills',
'foreignKey' => 'project_id',
'associationForeignKey' => 'skill_id',
'dependent' => true,
//'conditions' => array('Advertisement.advertisement_is_active' => '1')
),
'Attachment' =>
array(
'className' => 'Attachment',
'joinTable' => 'attachments_projects',
'foreignKey' => 'project_id',
'associationForeignKey' => 'attachment_id',
)
);
public function beforeSave($options = array()) {
parent::beforeSave($options = array());
foreach (array_keys($this->hasAndBelongsToMany) as $model):
if(isset($this->data[$this->alias][$model])):
$this->data[$model][$model] = $this->data[$this->alias][$model];
unset($this->data[$this->alias][$model]);
endif;
endforeach;
return true;
}
}
Skill Model
class Skill extends AppModel {
public $name = 'Skill';
public $hasOne = array('Exam');
public $hasAndBelongsToMany = array(
'Category' =>
array(
'className' => 'Category',
'joinTable' => 'categories_skills',
'foreignKey' => 'skill_id',
'associationForeignKey' => 'category_id',
'dependent' => true
),
'Profile' =>
array(
'className' => 'Profile',
'joinTable' => 'profiles_skills',
'foreignKey' => 'skill_id',
'associationForeignKey' => 'profile_id',
'dependent' => true
),
'Project' =>
array(
'className' => 'Project',
'joinTable' => 'projects_skills',
'foreignKey' => 'skill_id',
'associationForeignKey' => 'project_id',
//'dependent' => true
)
);
}
Attachment Model
class Attachment extends AppModel{
public $name = 'Attachment';
public $hasAndBelongsToMany = array(
'Project' =>
array(
'className' => 'Project',
'joinTable' => 'attachments_projects',
'foreignKey' => 'attachment_id',
'associationForeignKey' => 'project_id',
'dependent' => true,
)
);
}

Answer 1

Pass Skill id not the field name of relation model
[Skill] => Array
(
[0] => Array
(
[id] => 14
)
[1] => Array
(
[id] => 16
)
)
