CakePHP发现没有在查询中插入正确的引号

I am using this code to make a list of truck types counted and sorted by type.

$count['type'] = $this->Type->find('all',
        array('joins' => array(
            array(
                'table' => 'truck_has_types',
                'alias' => 'TruckHasTypes',
                'type' => 'LEFT',
                'conditions' => array(
                    'Type.id' => 'TruckHasTypes.types_id',
                )
            )
        ),
        'fields' => array(
            'Type.id',
            'Type.name',
            'COUNT(TruckHasTypes.types_id) as N'),
            'group' => 'TruckHasTypes.types_id'
        )
    );

The query only returns a single result even thought there should be many more. I found the culprit. The query looks like this (got this from sql_dump)

SELECT `Type`.`id`, `Type`.`name`, COUNT(`TruckHasTypes`.`types_id`) as N FROM `douglass_cake`.`types` AS `Type` LEFT JOIN `douglass_cake`.`truck_has_types` AS `TruckHasTypes` ON (`Type`.`id` = 'TruckHasTypes.types_id') WHERE 1 = 1 GROUP BY `TruckHasTypes`.`types_id`

You can see that

ON (`Type`.`id` = 'TruckHasTypes.types_id')

Does no have the same quotes as

ON (`Type`.`id` = `TruckHasTypes`.`types_id`)

I have added those quotes manually in phpmyadmin and the query is successful, but I cannot not get cakephp to automatically generate this query. Any ideas?

Thank you! Ryan

    Do it this way:

    $count['type'] = $this->Type->find('all',
        array(
            'joins' => array(
                array(
                    'table' => 'truck_has_types',
                    'alias' => 'TruckHasTypes',
                    'type' => 'LEFT',
                    'conditions' => array(
                        'Type.id=TruckHasTypes.types_id',
                    )
                )
            ),
            'fields' => array(
                'Type.id',
                'Type.name',
                'COUNT(TruckHasTypes.types_id) as N'
            ),
            'group' => 'TruckHasTypes.types_id'
        )
    );
