Cakephp, Retrieve Data for HABTM Models using conditional find

Question

There are 2 Models: Project & Category that are bind with HABTM relationship. I would like to perform a search from projects controller that can do the following:

FIND all DISTINCT Project.scedule WHERE Category.slug != 'uncategorised'

Apologies for the syntax, I'm no sequel expert.

What I have managed to do is to retrieve all projects that do not belong to Category uncategorised into an array however I'm not sure as to how to search again the array result for DISTINCT Project.schedule values (needed to fill out a form drop down)

Answer 1

Before answer this question,again I suggest you to read the HABTM in cookbook of CAKEPHP carefully,then you can finish jobs like this yourself.

$this->Project->bindModel(array(
'hasOne' => array(
    'CategorysProject',
    'FilterCategory' => array(
        'className' => 'Category',
        'foreignKey' => false,
        'conditions' => array('FilterCategory.id = CategorysProject.category_id')
))));
$this->Project->find('all', array(
    'fields' => array(DISTINCT (Project.scedule)),
    'conditions'=>array('FilterCategory.slug !='=>'uncategorised')
));
