Hey all,
Trying to use GROUP by in containable behaviour and it's not working as
expected.
Ratings model has fields: *Rating.id, Rating.restaurant_id, Rating.rating
(1-5)*
I have a query (which amongst other things) fetches the average + total
ratings for a restaurant:
$restaurant = $this->Restaurant->find('first', array(
'fields' => array(Restaurant.x, Restaurant.y, Restaurant.z),
'contain' => array(
'model1' => array(x, y, z),
* 'Rating' => array(*
* 'fields' => array(*
* 'AVG(Rating.rating)',*
* 'COUNT(Rating.id)'*
* )*
* ),*
'model2' => ...
)
));
It works fine on my mysql version 5.0 on my dev server but as soon as I
upload it onto live site mysql 4.1 I get error saying I *cannot mix group
columns (avg, sum, etc) is illegal without a GROUPBY field.*
So ok fair play, I'm not including a groupby field. I jumped in and added
one:
$restaurants = $this->Restaurant->find('all', array(
'fields' => array(Restaurant.x, Restaurant.y, Restaurant.z),
'contain' => array(
'model1' => array(x, y, z),
* 'Rating' => array(*
* 'fields' => array(*
* 'AVG(Rating.rating)',*
* 'COUNT(Rating.id)'*
* ),*
* 'group' => 'Restaurant.id' // I also tried 'group' => 'id'*
* ),*
'model2' => ...
)
));
Which I would figure works but it doesn't. I get an error saying that *there
is no column called 'group'* and it is trying to execute this query:
SELECT `Rating`.`restaurant_id`, AVG(`Rating`.`rating`),
COUNT(`Rating`.`id`), `Rating`.`group` FROM `ratings` AS `Rating` WHERE
`Rating`.`restaurant_id` = (5)
Am I using containable incorrectly?
