i developing web application using angular js , sails. struck issue.in application there menu, displays different count values database.plz see back

getallcountmyprofile: function(req,res){ usertokenservice.checktoken(req.get('user-token'), function (err, tokencheck) { var userid = tokencheck.tokendetails.userid;  var query = "select (select count(*) review userid="+ userid +" , approvalstatus = 'approved') reviewreceived ,"+       " (select count(*) review reviewerid="+ userid +" ) reviewpenned, "+       "(select count(*) photos userid="+ userid +" , accesstype='private' , status='active') privatephotocount, "+       "(select count(*) photos userid="+ userid +" , accesstype='public' , status='active') publicphotocount";  review.query(query, function (err, photoreviewcount) {         if(err){             console.log("error"+ err);         }         else{              return res.json(200, {status:4, message:'success',data1:photoreviewcount});         }     }); userservice.checkvideolimit(userid, function (err, videocount)        {          var novideos=videocount.data;         console.log("video count "+novideos);         return res.json(200, {status: 1, data2: videocount});      }); var query="select sum(rating) totalrating,count(*) totalcount review userid=" +userid+ "";        review.query(query, function (err, avgrating) {         if(err){             console.log("error"+ err);         }         else{             var rating=json.stringify(result);             var totalrating=result[0].totalrating;             var count=result[0].totalcount;             var avgratingvalue=(totalrating/count).tofixed(2);             console.log(totalrating,count);             console.log("avgrating"+rating);             return res.json(200, {status:4, message:'success',data3:avgrating});         }     });    });` }

if execute each return response got result. if execute above query , got error message on console "can't set headers after sent." need result data1,data2, data3. solution obtain this?

you cannot set response more 1 time. either can use res.write , edit response queries , send res.end() or can change code send response once. this:

res.status(200).json({      "data":{           "data1":photoreviewcount,           "data2":videocount,            "data3":avgrating             } })

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. :)
