If I'm interpreting it correctly, you have a table 'likes' that has the
following fields:
user_id (unique, represents the user_id of the person who is liked)
count (number of users who indicated that they like this user_id)
so that Like belongsTo User, and conversely, User hasOne Like. Assuming that
both User and Like have the same dataSource, have you tried:
$this->paginate('User', array(
'contain' => array('Like'),
'conditions' => array(
'Like.count >' => 0
),
'order' => array(
'Like.count' => 'desc',
'Like.modified' => 'asc'
)
);
instead of using Like::getMostLiked() then running individual queries for
each user in the resulting array.
Because User hasOne Like, the ContainableBehavior uses a LEFT JOIN between
User and Like, so Like.count is in the scope of the SQL query, and you
should be able to use it as part of the $options['order']. Or as an
alternative, you can also try:
$this->paginate('Like', array(
'contain' => array('User'),
'conditions' => array(
'Like.count >' => 0
),
'order' => array(
'Like.count' => 'desc',
'Like.modified' => 'asc'
)
);
Either one should work, since there's a one-to-one relation between the two
models. And since only one SQL query is executed (instead of 1 + $limit,
because you currently run 1 SQL query for Like::getMostLiked, and then
individual queries for each of the user_id values), it should be a little
faster and less resource-intensive.
