php - Symfony FOS Rest Bundle Api Call Many to Many Relationship -

i seem have issue. , i'm sure has simple fix. have api uses fos rest bundle. have call sends post request postcreatetimesheetaction( request $request ) creates empty row in timesheet table. have call patchtimesheetaction laters adds data table. okay well. have call patchcareoptionaction( timesheet $timesheet ) creates row in table has many many relationship built careoptions.php(below) , timesheet.php(below). api calls work , function should. post them below here:

creates blank new timesheet row in timesheet table: (timesheet.php)

curl -h "accept: application/json" -h "content-type: application/json" -i -x post -d '{"homecare_homecarebundle_timesheet":""}' www.hc-timesheets-demo.com/app_dev.php/api/v1/create/timesheet

updates timesheet row data:

curl -i -h "accept: application/json" -h "content-type: application/json" -d '{"homecare_homecarebundle_timesheet":{"agency":"157","recipient":"154","pca":"16","service":"6"}}' -x patch www.hc-timesheets-demo.com/app_dev.php/api/v1/timesheet/31

and creates many many relationship:

curl -i -h "accept: application/json" -h "content-type: application/json" -d '{"homecare_homecarebundle_timesheet":{"careoption":[456,457] }}' -x patch www.hc-timesheets-demo.com/app_dev.php/api/v1/careoption/31

notice 31 @ end of patch request. id of timesheet created in table first api call. lets question! whenever call 3rd api call create many many rows in table. when call again not replace old rows new ones. adds more rows table. want many many table rows updated , old ones gone. need delete them out first? let me explain little more. if see in 3rd api call i'm adding 2 careoptions timesheet: (careoptions 456 , 457). if call again, , lets want add 458 , 459. want 456 , 457 automatically delete , gone. please me out??!!

you need either call second api delete 2 previous added options, or in updatetimesheet delete 2 previous added options, can select them query creating function in repository :

public function getlasttwocareoptions(){  $query = "select co.id careoptiontable co inner join timesheettable ts ts.id = timesheetid order co.id limit 2;";  $connection = $this->getentitymanager()->getconnection(); $prep_query = $connection->prepare($req); $result = $prep_query->fetchall(); } 

you can make limit parameter function if may need update 3 last care options someday or more.

then ids , remove them timesheet. solution use same query differently delete them sql query without having select , delete.
