node.js - Sailsjs: How to populate association after *update* to model? -


i have following controller code works index, show, create methods update fails when include populate - doing wrong?

  // user list   index: function(req, res) {     user.find()     .populate('profile')     .exec(function(err, users) {       if (err) return res.json(err, 400);       if (!users) return res.json(users, 404);       res.json(users, 200);     });   },    // single user   show: function(req, res) {     user.findone({ username: req.param('username') })     .populate('profile')     .exec(function(err, user) {       if (err) return res.json(err, 400);       if (!user) return res.json(user, 404);       res.json(user, 200);     });   },    // create user   create: function(req, res) {     user.create(req.body, function(err, user) {       if (err) return res.json(err, 400);       person.create({user: user.id, slug: user.username}, function(err, profile) {         if (err) return res.json(err, 400);         user.update(user.id, {profile: profile.id})         .populate('profile')         .exec(function(err, user) {           if (err) return res.json(err, 400);         });         user.profile = profile;         res.json(user, 200);       });     });   },    // update user   update: function(req, res) {     var username = req.param('username');     user.update({ username: username }, req.body)     .populate('profile')     .exec(function(err, user) {       if (err) return res.json(err, 400);       res.json(user, 201);     });   },

as per documentation update function takes callback passes updated records. example doc :

// example, update user's name, // .update(query, params change, callback) user.update({   name: 'sally' },{   phone: '555-555-5555' }, function(err, users) {   // error handling   if (err) {     return console.log(err);   // updated users successfully!   } else {     console.log("users updated:", users);   } });

applied code, :

// update user update: function(req, res) {   var username = req.param('username');   user.update({ username: username }, req.body)   .exec(function(err, users) {     if (err) {       return res.json(err, 400);     }      var user = users.slice(0,1); // take first user in array     user.findone(user.id) // may try user._model(user) instead avoid roundtrip db.     .populate('profile')     .exec(function(err, user) {       if (err) {         return res.json(err, 400);       }       res.json(user, 201);     });   }); }

c# - OpenXML hanging while writing elements -

i have program pulls data database, caches file , exports data multiple formats (excel, excel 2003, csv). i'm using openxml sdk 2.0 excel work. these export processes run in parallel (using parallel.foreach ), , amount of data can pretty large - e.g. csvs 800mb. during these larger exports, i've noticed writing of xml documents hang. instance, if have 8 exporting in parallel, @ point "pause". hang around same point: //this.writer openxmlwriter created worksheetpart. this.writer.writeelement(new cell() { cellvalue = new cellvalue(value), datatype = cellvalues.string }); when happens, pause debugger (vs2013 in case) , notice threads blocking around same portion of code - bit deeper in openxml sdk - stem call openxmlwriter.writeelement . i dug through source using justdecompile didn't find answers. appears there intermediary stream in use writing isolated storage , is, reason, blocking. underlying stream each of these filestream . here screenshot ...
