Display of data on view from route.js

    // This is my router.js


    router.get('/restful', function(req, res){
    console.log("before");
      User.show_deatils(req, res, function(err, resultArray){
       if(!err){
        req.session.resultArray=resultArray;
        req.session.save();
      }
      });
      //console.log(req.session.resultArray)
     res.render('restful',{resultArray:req.session.resultArray});   
     });


    //This is model.js
    module.exports.show_deatils=function(req,res,callback){

      var resultArray=[];
      mongo.connect(url,function(err,db){
        assert.equal(null,err);
        var cursor=db.collection('users').find();
        cursor.forEach(function(doc,err){
          assert.equal(null,err);
          resultArray.push(doc);
        callback(null, resultArray); 


        });


    });

    }

//I want to display the resultArray on loading view(restful.ejs).But the problem is when I first redirect to the page.It is not showing any value.But upon clicking the same page its been showing me the details.What I feel is on the first load it is not storing the values in session.How can we solve this issue?I am trying this for long time.

That is because you are rendering outside the async callback function Change your code like this

 router.get('/restful', function(req, res){
    console.log("before");
      User.show_deatils(req, res, function(err, resultArray){
       if(!err){
        req.session.resultArray=resultArray;
        req.session.save();
        res.render('restful',{resultArray:req.session.resultArray});   

      }
      });
      //console.log(req.session.resultArray)
     });

It is storing correct in the session, that part is working but since the first time you are rendering outside the async callback, it has no value.
