  • Marionette multi user/roles application

    - by Fabrizio Fortino
    I have to build a pretty complex application using Backbone Marionette. The user interface has to handle multiple users with different roles. For example the 'admin' user will see the complete menu whereas the 'guest' user will access a subset of the same menu. Moreover some views will be accessible to all the users but the functions inside them (add, edit, delete) need to be profiled on the different roles. I am not sure about the right approach to use in order to solve this issue. I could have different templates for the different roles but in this case plenty of code will be duplicated inside them. Is there any best practice (or maybe some example) to sort my problem out using Marionette? Thanks in advance, Fabrizio

  • A elusive multi level accordion

    - by juanpablo

  • Ajax Post Request Returns JSON but Deferred Fails

    - by imrane
    I have a cross-domain POST request to http://api.local/user/auth - my API endpoint. I allow Cross Domain requests in my api with CORS. Using Chrome if that makes a difference. I get a valid server JSON response with 200 Status Code but I am using deferreds from a backbone model like so: @model.save() .fail(-> console.log 'sync fail') .success -> console.log 'sync OK' And I consistently get a 'sync fail' instead of the expected 'sync OK' Thoughts?

    When I make a setup project in VS 2008, and select <Setup Project>, Properties, PreRequisites then i can select SqlExpress2005 to be automatically included. What I am looking for is a walkthrough of how to get SqlExpress2008 included in the same manner. Second choice would be how to get (or make) a MergeModule (MSM) file to do the same.

  • Socket.io - Tutorials? Better docs?

    - by mattbasta
    I've been toying around with nodejs for some of my COMET stuff and stumbled across Socket.io. Unfortunately, the documentation is fairly lacking and there is only one "real" example. Is anyone familiar with some decent tutorials on some of the intricacies of this library? Maybe just some better docs? I'd really like to use it, but I'm probably going to avoid it if I can't figure how to use it properly.

  • a script translatable to JavaScript with callback-hell automatic avoider :-)

    - by m1uan
    I looking for "translator" for JavaScript like already is CoffeScript, which will be work for example with forEach (inspired by Groovy) myArray.forEach() -> val, idx { // do something with value and idx } translate to JavaScript myArray.forEach(function(val, idx){ // do something with value and idx }); or something more usefull... function event(cb){ foo()-> err, data1; bar(data1)-> err, data2; cb(data2); } the method are encapsulated function event(cb){ foo(function(err,data1){ bar(data1, function(err, data2) { cb(data2); }); }); } I want ask if similar "compiler" to JavaScript like this even better already doesn't exists? What would be super cool... my code in nodejs looks mostly like this :-) function dealer(cb){ async.parallel([ function(pcb){ async.watterfall([function(wcb){ first(function(a){ wcb(a); }); }, function(a, wcb){ thirt(a, function(c){ wcb(c); }); fourth(a, function(d){ // dealing with “a” as well and nobody care my result }); }], function(err, array_with_ac){ pcb(array_with_ac); }); }, function(pcb){ second(function(b){ pcb(b);}); }], function(err, data){ cb(data[0][0]+data[1]+data[0][1]); // dealing with “a” “b” and “c” not with “d” }); } but, look how beautiful and readable the code could be: function dealer(cb){ first() -> a; second() -> b; third(a) -> c; // dealing with “a” fourth(a) -> d; // dealing with “a” as well and nobody care about my result cb(a+b+c); // dealing with “a” “b” and “c” not with “d” } yes this is ideal case when the translator auto-decide, method need to be run as parallel and method need be call after finish another method. I can imagine it's works Please, do you know about something similar? Thank you for any advice;-)

  • running requestAnimationFrame from within a new object

    - by JVE999
    I'm having trouble running an animation. This is inside var ob1 = function() {};. When called, it runs for a while and then I get the error Uncaught RangeError: Maximum call stack size exceeded. However, this same structure has no problems running outside of the object. /////////////// Render the scene /////////////// this.render = function (){ renderer.render(scene,camera); if(isControls == true) controls.update(clock.getDelta()); this.animate(); //console.log(true); requestAnimationFrame(this.render()); } /////////////// Update objects /////////////// this.animate = function (){ console.log("!"); }

  • MongoDb - $match filter not working in subdocument

    - by Ranjith
    This is Collection Structure [{ "_id" : "....", "name" : "aaaa", "level_max_leaves" : [ { level : "ObjectIdString 1", max_leaves : 4, } ] }, { "_id" : "....", "name" : "bbbb", "level_max_leaves" : [ { level : "ObjectIdString 2", max_leaves : 2, } ] }] I need to find the subdocument value of level_max_leaves.level filter when its matching with given input value. And this how I tried, For example, var empLevelId = 'ObjectIdString 1' ; MyModel.aggregate( {$unwind: "$level_max_leaves"}, {$match: {"$level_max_leaves.level": empLevelId } }, {$group: { "_id": "$level_max_leaves.level", "total": { "$sum": "$level_max_leaves.max_leaves" }}}, function (err, res) { console.log(res); }); But here the $match filter is not working. I can't find out exact results of ObjectIdString 1 If I filter with name field, its working fine. like this, {$match: {"$name": "aaaa" } }, But in subdocument level its returns 0. {$match: {"$level_max_leaves.level": "ObjectIdString 1"} }, My expected result was, { "_id" : "ObjectIdString 1", "total" : 4, }

  • Javascriptlibrary more efficient than Rickshaw for realtime visualizations

    - by dan kutz
    I want to visualize data as time-series graphs on mobile devices(tablets) and therefore stumbled upon rickshaw, which is based on D3. First I must say I was a little bit confused when I realized that realtime in web design is defined totally different to realtime in engineering which has fixed(and often very short) timeframes. Anyway my aim is to visualize the data as fast as possible, and on older tablets visualization with rickshaw is quite slow. Can anybody recommend another library, which may be more efficient in rendering? Or is there no way out and I have to go native? regards Dan.

  • Ember nested route. Load more models

    - by user3568719
    JsBin http://jsbin.com/EveQOke/153/ I know how to load more then one model to a route, using Ember.RSVP.hash. (see Jsbin Children menu). I use dynamic part to access one elem from a collection children/1. But i cant load more models to a nested resource. In my example i want to populate all the toys for a select, not just list the toys of the child. I have tried to access the model of the route children App.ChildRoute = Ember.Route.extend({ model: function(param){ return Ember.RSVP.hash({ allToys: this.modelFor("children"), child:this.store.find('child', param.child_id) }); } }); and use its model's toy property (since there have already loaded all of the toys) child.hbs <h4>All avaiable toys</h4> <table> {{#each toy in model.allToys.toys}} <tr> <td>{{toy.name}}</td> </tr> {{/each}} </table>

  • Update graph in real time from server

    - by user1869421
    I'm trying to update a graph with received data, so that the height of the bars increase as more data is received from the server via a websocket. But my code doesn't render a graph in the browser and plot the data points. I cannot see anything wrong with the code. I really need some help here please. ws = new WebSocket("ws://localhost:8888/dh"); var useData = [] //var chart; var chart = d3.select("body") .append("svg:svg") .attr("class", "chart") .attr("width", 420) .attr("height", 200); ws.onmessage = function(evt) { var distances = JSON.parse(evt.data); data = distances.miles; console.log(data); if(useData.length <= 10){ useData.push(data) } else { var draw = function(data){ // Set the width relative to max data value var x = d3.scale.linear() .domain([0, d3.max(useData)]) .range([0, 420]); var y = d3.scale.ordinal() .domain(useData) .rangeBands([0, 120]); var rect = chart.selectAll("rect") .data(useData) // enter rect rect.enter().append("svg:rect") .attr("y", y) .attr("width", x) .attr("height", y.rangeBand()); // update rect rect .attr("y", y) .attr("width", x) .attr("height", y.rangeBand()); var text = chart.selectAll("text") .data(useData) // enter text text.enter().append("svg:text") .attr("x", x) .attr("y", function (d) { return y(d) + y.rangeBand() / 2; }) .attr("dx", -3) // padding-right .attr("dy", ".35em") // vertical-align: middle .attr("text-anchor", "end") // text-align: right .text(String); // update text text .data(useData) .attr("x", x) .text(String); } useData.length = 0; } } Thanks

  • Visual Studio Question: How to go to a specific file path and line number programmatically?

    - by Jack
    In the Visual Studio output window, you can double click a line that contains a file path and line number and it automatically takes you to that location. In my program, I need to mimic this behavior and be able to click something (a button for example) and do go to a specific file and line number that I tell it to go to. Any help/suggestions would be appreciated. I am working in C#.

  • why does backbone not send the delete?

    - by Nippysaurus
    I have a very basic backbone (sample) application which just creates and destroys model items. When the model is created the object is persisted with a POST to the web server, but when the model is destroyed there is no DELETE sent to the server? Any idea why this might be? very basic model: window.User = Backbone.Model.extend({ urlRoot: 'users' }); my test code just to create and delete the model: var model = null; $(".add").click(function(){ if (model == null) { model = new window.User; model.set({name: 'meeee'}); model.save(); } }); $(".remove").click(function(){ if (model != null) { model.destroy(); } }); The JSON response when creating the model seems good too:

  • Locating SSL certificate, key and CA on server

    - by jovan
    Disclaimer: you don't need to know Node to answer this question but it would help. I have a Node server and I need to make it work with HTTPS. As I researched around the internet, I found that I have to do something like this: var fs = require('fs'); var credentials = { key: fs.readFileSync('path/to/ssl/private-key'), cert: fs.readFileSync('path/to/ssl/cert'), ca: fs.readFileSync('path/to/something/called/CA') }; var app = require('https').createServer(credentials, handler); I have several problems with this. First off, all the examples I found use completely different approaches. Some link to .pem files for both the certificate and key. I don't know what pem files are but I know my certificate is .crt and my key is .key. Some start off at the root folder and some seem to just have these .pem files in the application directory. I don't. Some use the ca thing too and some don't. This CA is supposed to be my domain's CA bundle according to some articles - but none explain where to find this file. In the ssl directory on my server I have one .crt file in the certs directory and one .key file in the keys directory, in addition to an empty csrs directory and an ssl.db file. So, where do I find these 3 files (key, cert, ca) and how do I link to them correctly?

  • d3: Coloring Multiple Lines from Nested Data

    - by diet_coke
    I'm currently assembling some line graphs with circles at the datapoints from arrays of JSON objects formatted like so: var data = [{ "name": "metric1", "datapoints": [ [10.0, 1333519140], [48.0, 1333519200] ] }, { "name": "metric2", "datapoints": [ [48.0, 1333519200], [12.0, 1333519260] ] }] I want to have a color for each metric, so I'm trying to color them based on the index of the object within the array data. The code I have currently for just placing the circles looks like: // We bind an svg group to each metric. var metric_groups = this.vis.selectAll("g.metric_group") .data(data).enter() .append("g") .attr("class", "metric_group"); // Then bind a circle for each datapoint. var circles = metric_groups.selectAll("circle") .data(function(d) { return d.datapoints; }); circles.enter().append("circle") .attr("r", 3.5); Now if I change that last bit to something like: circles.enter().append("circle") .attr("r", 3.5); .style("fill", function(d,i) { return i%2 ? "red" : "blue"; } I get alternating red and blue circles, as could be expected. Taking some advice from Nested Selections : 'Nesting and Index', I tried: circles.enter().append("circle") .attr("r", 3.5); .style("fill", function(d,i,j) { return j%2 ? "red" : "blue"; } Which doesn't work (j is undefined), presumably because we are in the named property datapoints, rather than an array element. How might I go about doing the coloring that I want without changing my data structure? Thanks!

  • How can I show the "Upload" tab in CKEditor?

    - by Hermet
    Hi guys, I've checked the CKEditor developer documentation and also some solved questions in here about this editor but couldn't find one which helped me. The thing is, I have set up CKEditor and when I get into the images dialog I can't see any "Upload" tab. I am trying to set up a custom file uploader, and according to the documentation is something like this: <script type="text/javascript"> CKEDITOR.replace( 'cuerpo', { filebrowserBrowseUrl : '/imgs/explorador.php', filebrowserUploadUrl : '/imgs/subirImagenes.php' }); </script> Thank you, and apologies for my English.

  • No parameterless constructor defined for this object when simply copying site

    - by jaffa
    I'm getting the above error. All I have done is copied an existing site and set-up debugging to use a different port using IISExpress in Visual Studio. Any ideas why I would suddenly get this error? Normally I get this error when StructureMap cannot for some reason resolve a dependency to inject into a controller. But this has me stumped. The code-base is the same. All I've done is copied the code into another folder!?!

  • getting data from dynamic schema

    - by coure2011
    I am using mongoose/nodejs to get data as json from mongodb. For using mongoose I need to define schema first like this var mongoose = require('mongoose'); var Schema = mongoose.Schema; var GPSDataSchema = new Schema({ createdAt: { type: Date, default: Date.now } ,speed: {type: String, trim: true} ,battery: { type: String, trim: true } }); var GPSData = mongoose.model('GPSData', GPSDataSchema); mongoose.connect('mongodb://localhost/gpsdatabase'); var db = mongoose.connection; db.on('open', function() { console.log('DB Started'); }); then in code I can get data from db like GPSData.find({"createdAt" : { $gte : dateStr, $lte: nextDate }}, function(err, data) { res.writeHead(200, { "Content-Type": "application/json", "Access-Control-Allow-Origin": "*" }); var body = JSON.stringify(data); res.end(body); }); How to define scheme for a complex data like this, you can see that subSection can go to any deeper level. [ { 'title': 'Some Title', 'subSection': [{ 'title': 'Inner1', 'subSection': [ {'titile': 'test', 'url': 'ab/cd'} ] }] }, .. ]

  • Looking for a 'pick a-or-b' voting system script

    - by user324455
    Apologies: this is my first time on stackoverflow and I'm starting with a question and seeking advice. Sorry. Caveats: I know HTML and CSS pretty well. Javascript and PHP are not completely alien, but I'm really pretty basic on those. That said, I'm pretty sharp and willing to search for explanations independently. Ok, so my question is this: I want to create a site with a voting system very much like the one on kittenwar.com - the page loads 2 random images from a db of some sort and you click on the one you want to 'win'. Ranked pairs kind of deal. Then there is a leaderboard of those images which have the highest win-loss ratio. There also needs to be an uploader for peeps to upload their own images and have them go into an approval workflow, and from there into the db that feeds the voting thing. I tried a pre-made solution ('photo battle') but found it was completely standalone, so trying to integrate it or change any of the options was a nightmare, plus it was buggy. i'm sure there has to be a relatively easy way to do this, right? Ideally I'd like to build my site in Joomla and integrate this functionality somehow. I'd be very grateful for any advice on this. Thanks Tom
