php - Doctrine - ManytoMany Filter Result -


i need filter result many many relationship in doctrine.

class users extends recorditem {     /**     * @id @column(type="integer") @generatedvalue     * @var int     **/      protected $id;      /**      * @manytomany(targetentity="company")      * @jointable(name="users_join_company",      *      joincolumns={@joincolumn(name="user_id", referencedcolumnname="id")},      *      inversejoincolumns={@joincolumn(name="company_id", referencedcolumnname="id")}      *      )      */     protected $companys;      /**     * @column(type="string", length=100)     * @var string     */     protected $username;        //edit - > added array collection - forgotten     public function __construct() {         $this->companys = new arraycollection();     } }  class company extends recorditem {      /**     * @id @column(type="integer") @generatedvalue     * @var int     **/     protected $id;      /**     * @column(type="string", length=100)     * @var string     */     protected $company_name;   }

so far i'm able query company following code, there proper way add filter? example: there 3 company in array collection, want return 1 specify company "id"

$user = $entitymanager->getrepository('users')->findoneby(['id'=>1]);  $companys = $user->companys; // hope return company id 1  foreach($companys $company){     echo $company->company_name; }

if want filter collection, use arraycollection ...

http://doctrine-orm.readthedocs.io/projects/doctrine-orm/en/latest/reference/working-with-associations.html

example : 

// guess companies arraycollection $mydesiredcompanies = $companies->filter(function (company $entry) {     return ($entry->getid() == 1); });

it filter collection , return new collection desired results

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
