got a select that does 10 query in doctrine (Symfony)
I currently have a big problem with my symfony app, I have a complexe sql query that makes too much connections the the database.
The query order, search for keyword using doctrine searchable, and check the geo position.
Here the complete model pasted and the sql log, anyone got an idea what I am doing wrong ? :/
public function getListItems($orderby, $budget, $motscles, $userid, $catID, $useDistance = true)
{
// CHANGE ORDER
if(!$orderby){
$orderby = "a.created_at DESC";
}else if($orderby == "price"){
$orderby = "a.price ASC";
}else if($orderby == "date") {
$orderby = "a.created_at DESC";
}else{
$orderby = "a.created_at DESC";
}
// Search Keywords in table
if($motscles){
$searchItem = Doctrine_Core::getTable('csw_Article');
$results = $searchItem->search($motscles);
$ids = array();
foreach ($results as $result) {
$ids[] = $result['id'];
}
if(sizeof($ids) == 0){
$ids[] = 0;
}
}
$q = Doctrine_Core::getTable('csw_Article')
->createQuery("a")
->leftJoin('a.csw_CategorieArticle ca');
$sfContext = sfContext::getInstance()->getUser();
if($useDistance){
$lat = (string)($sfContext->getAttribute('userLat')) ? $sfContext->getAttribute('userLat') : sfConfig::get("app_user_lat");
$long = (string)($sfContext->getAttribute('userLong')) ? $sfContext->getAttribute('userLong') : sfConfig::get("app_user_long");
$radius = 18;
$q->select("a.longitude, a.latitude, (3959 * acos(cos(radians('".$lat."')) * cos(radians(latitude)) * cos(radians(longitude) - radians('".$long."')) + sin(radians('".$lat."')) * sin(radians(latitude)))) AS distance");
$q->having("distance < ?", $radius);
}
if($orderby == "distance") {
$q->orderBy("distance desc");
}
$q->addOrderBy($orderby);

回答1:
You can enable xdebug_loggin to find out where you queries originate from:
//factories.yml
dev:
logger:
param:
loggers:
sf_web_debug:
param:
xdebug_logging: true
This will log the trace to each query and should give you a clue what went wrong
回答2:
I think that the problem is not how are you doing the query but in how are you using it in the action or at the view. I guess that you're doing something like:
foreach($items as $item){
$model->getListItems(...);
}
So there'll be one call to db for each $item. Try to use WhereIn instead of addWhere when filter by user.
