Find an array for hasMany relationship

I have relations li开发者_开发百科ke this:

• Project has multiple Properties
• Property has multiple Rates

On the project page, I want to display:

• The project, its properties and its latest rate

So far, I have this:

$this->set('rates', $this->Rate->find('all', array(
    'conditions' => array('Property.project_id' => $id),
    'fields' => array('Rate.id', 'Rate.rate', 'Rate.floor_rise', 'Property.id'),
    'order' => array('Rate.created DESC')
)));

This gives all rates for the respective property, but I only want the latest rate.

How should I do this query?

Change 'all' to 'first' in your find, and as you already have a good 'order' you should be fine.

$this->set('rates', $this->Rate->find('first', array(
'conditions' => array('Property.project_id' => $id),
'fields' => array('Rate.id', 'Rate.rate', 'Rate.floor_rise', 'Property.id'),
'order' => array('Rate.created DESC')

)));
