  • How to detect invalid route and trigger function in Backbone.Controller

    - by tomodian
    Is there any method to detect invalid (or undefined) route and trigger 404 page in Backbone.Controller? I've defined routes in my Controller like this, but it didn't work. class MyController extends Backbone.Controller routes: "method_a": "methodA" "method_b": "methodB" "*undefined": "show404Error" # when access to /#method_a methodA: -> console.log "this page exists" # when access to /#method_b methodB: -> console.log "this also exists" # when access to /#some_invalid_hash_fragment_for_malicious_attack show404Error: -> console.log "sorry, this page does not exist"

  • Why does passing arguments to the command in an env invocation not work?

    - by timdisney
    I have a shell script to run node with some arguments like so: #!/usr/bin/env node --harmony_proxies ... This works fine under OS X but in Ubuntu it errors with: /usr/bin/env: node --harmony_proxies: No such file or directory Node is definitely installed and on the PATH since if I remove the --harmony_proxies flag it works fine. Is there some different way of passing arguments when using env in Ubuntu?

  • How to reference {{outlet}} in Ember.CollectionView's itemView

    - by ceed
    I am new to ember and ran into a problem and could not find an answer online. I have a collectionView App.MyView = Ember.CollectionView.extend({ itemViewClass: 'App.MyViewItem', contentBinding: 'controller' }); and the itemViewClass App.MyViewItem = Ember.View.extend({ templateName: 'mytemplate' }); the template looks like that: <div {{action 'select' view.content}}>{{view.content.name}}</div> {{outlet detail}} </div> This produces the content list just fine. In the controller, I have an action: select: function(evt){ this.transitionToRoute('item', evt); } What I want to do is to transition to a nested route when selecting the item (which works fine) and also load more data of the selected item into {{outlet detail}}. While I can load the content of the "item" route into an outlet of e.g. application.hbs, I don't know how to reference the outlet of the selected collectionView item so that the detailed contents are displayed within the existing view. I tried to use: this.render('item', { outlet: 'detail', into: '????' }); within the item Route, but I don't know how to reference the collectionview item template. Maybe there's also a much easier way of loading more data from an item in the item's view (while changing the route at the same time). Any help would be appreciated.

    - by Ilya Rusanen

Thats why I have to pass some parameter. But res.redirect('back', (reg_error:'username')}) can not be used directly 'cause res.redirect() doesn't support parameters. How can I render prevous page with some parameter? Thanks!

  • How to set up Node server for production on own machine?

    - by Matt Hintzke
    This must be a pretty basic thing to do, but I cannot find any good guide on how to do it on the internet. I only find how to set up a development environment for Node. I want to be able to forward my R-Pi's port 80 to my Node server, which I want to obviously listen on port 80. How can I close the native port 80 so that I can let me Node server listen on that port. Ultimately, I want to be able to access my pi from any remote location. I know how to set up a static IP and forward the port on my router, but now how do I allow Node into port 80?

  • Multiple collections tied to one base collection with filters and eventing

    - by damienc88
    I have a complex model served from my back end, which has a bunch of regular attributes, some nested models, and a couple of collections. My page has two tables, one for invalid items, and one for valid items. The items in question are from one of the nested collections. Let's call it baseModel.documentCollection, implementing DocumentsCollection. I don't want any filtration code in my Marionette.CompositeViews, so what I've done is the following (note, duplicated for the 'valid' case): var invalidDocsCollection = new DocumentsCollection( baseModel.documentCollection.filter(function(item) { return !item.isValidItem(); }) ); var invalidTableView = new BookIn.PendingBookInRequestItemsCollectionView({ collection: app.collections.invalidDocsCollection }); layout.invalidDocsRegion.show(invalidTableView); This is fine for actually populating two tables independently, from one base collection. But I'm not getting the whole event pipeline down to the base collection, obviously. This means when a document's validity is changed, there's no neat way of it shifting to the other collection, therefore the other view. What I'm after is a nice way of having a base collection that I can have filter collections sit on top of. Any suggestions?

  • Socket.io Duplicate clients on a namespace

    - by Servernumber
    Hi I'm trying to use dynamic namespace to create them on demand. It's working except that I get duplicate or more client for some reason Server side : io.of("/" + group ).on("connection", function(socket_group) { socket_group.groupId = group; socket_group.on("infos", function(){ console.log("on the group !"); }) socket_group.on('list', function () { Urls.find({'group' : '...'}).sort({ '_id' : -1 }).limit(10).exec(function(err, data){ socket_group.emit('links', data); }); }) [...] }) Client Side : socket.emit('list', { ... }); On the client side only one command is sent but the server is always responding with 2 or more responses. Every time I close/open my app the response is incremented. Thanks if you find out.

  • Lost in Nodester Installation

    - by jslamka
    I am trying to install my own version of Nodester. I have tried on Ubuntu 12.04 LTS and now with CentOS. I am not the most skilled Linux user (~2 months use) so I am at a loss at this point. The instructions are located at https://github.com/nodester/nodester/wiki/Install-nodester#wiki-a. They ask you to "export paths (to make npm work)" with the lines necessary to accomplish this. cd ~ echo -e "root = ~/.node_libraries\nmanroot = ~/local/share/man\nbinroot = ~/bin" > ~/.npmrc echo -e "export PATH=3d9c7cfd35d3628e0aa233dec9ce9a44d2231afcquot;\${PATH}:~/bin3d9c7cfd35d3628e0aa233dec9ce9a44d2231afcquot;;" >> ~/.bashrc source ~/.bashrc I can accomplish all of this until I get to the source ~/.bashrc line. When I run that, I get the following: [root@MYSERVER ~]# source ~/.bashrc -bash: /root/.bashrc: line 13: syntax error near unexpected token ';;' -bash: /root/.bashrc: line 13: 'export PATH=3d9c7cfd35d3628e0aa233dec9ce9a44d2231afcquot;${PATH}:~/bin3d9c7cfd35d3628e0aa233dec9ce9a44d2231afcquot;; I have tried changing the quot; to " and that didn't help. I tried changing quot; to colons and that didn't help. I also removed that and it didn't help (I am sure many of you at this point are probably wondering why I would even try those things). Does anyone have any insight as to what I need to do to get this to run properly?

    - by lptrung
    Hi all! I have a problem when run animation with three.j. See example: http://jsfiddle.net/5ywdE/13/ When the green cube is rotated to position of the blue cube, the red cube will be rotated.

Can I set the cube which will be displayed in front of other cube in case of overlapped? What am I doing wrong?? Thanks in advance

  • A better and faster way for eval?

    - by user1707250
    I want to build my queries dynamically and use the following snippet: --snip-- module.exports = { get : function(req, res, next) { var queryStr = "req.database.table('locations').get(parseInt(req.params.id))"; if (req.params.id) { if (req.fields) { queryStr += '.pick(' + req.fieldsStr + ')'; } console.log(queryStr); eval(queryStr).run(function(result) { console.log(result); res.send(result); }); } else if (!req.params.id) { --snip-- However introducing eval opens up my code to injection (req.fields is filled with url parameters) and I see the response time of my app increase from 7 to 11ms Is there a smarter way to accomplish what I did here? Please advice.

  • Variable text in links with knockout

    - by Gepser
    I'm generating a list of links and they have not the same text but I don't know how to put a text with knockout. This is what I have: <a data-bind="attr: { href: 'Controller/Method/' + Id, 'Title': CurrentTask }"> <!-- I need the name of the CurrentTask here--> CurrentTask </a> So, the text I want to show appears only in the "alt" property but not in the text of the link. It works but I need that the name of the CurrentTask be the link and now it's just showing me everything like this: <a href...>CurrentTask</a> <a href...>CurrentTask</a> <a href...>CurrentTask</a> <a href...>CurrentTask</a> and I need this <a href...>I get this data from de controller</a> <a href...>Sometext</a> <a href...>OtherText</a> <a href...>Anything</a>

  • ExpressJS: What is the difference between app.local and res.local?

    - by aeyang
    I'm trying to learn Express and in my app I have middleware that passes the session object from the Request object to my Response object so that I can access it in my views: app.use((req, res, next) -> res.locals.session = req.session next() ) But app.locals is available to the view as well right? So is it the same if I do app.locals.session = req.session? Is there a convention for the types of things app.locals and res.locals are used for? I was also confused on what the difference is between res.render() and res.redirect()? When should each be used? Thanks for reading. Any help related to Express is appreciated!

  • Ember - ConnectOutlet - when does view change from preRender to inDom

    - by dagda1
    I am trying to get my head round the connectOutlet method and when a view that is returned from connectOutet is actually inserted into the DOM. The view that is created in connectOutlet leaves connectOutlet in the preRender state. connectOutlet: function(name, context) { // method body view = this.createOutletView(outletName, viewClass); if (controller) { set(view, 'controller', controller); } set(this, outletName, view); return view; } I've not tracked down where or when the view is inserted into the Dom and the view transitions to the inDom state. I suspect the runloop is at play and it transitions after the current runloop has finished. Can anyone shed any light on this?

  • start javascript code with $(function, etc

    - by YAmikep
    I am studying Backbone and the todo example apps from http://todomvc.com/ I have noticed there are 3 severals ways of starting the code in the files: $(function() { // code here }); $(function( $ ) { // code here }); (function() { // code here }()); I do not understand the differences and when I should use one over the other. I also saw some people using this to start their code: $(document).ready(function(){ // code here }); From what I have seen, this is the full way of writing it right? In a more general way, should I always include my javascript code into something like that in each files? Thanks for your advice.

  • YUI Calendar: how does it load the Sam's Skin CSS?

    - by dound
    I'm using YUI 2's calendar in YUI 3. How does it load Sam's skin CSS? I didn't manually include it (though it seems like I should so the user can download it in the one request I make to the combo loader for css). Strangely, I don't see it being downloaded nor do I see it in the JS files themselves. I must be overlooking it. This is how I'm loading the CSS and JS now: <head> ... <link rel="stylesheet" type="text/css" href="http://yui.yahooapis.com/combo?3.1.0/build/cssreset/reset.css&amp;3.1.0/build/cssfonts/fonts.css&amp;3.1.0/build/cssbase/base.css"/> ... </head> ... <!--and at the end of the body tag:--> <script type="text/javascript" src="http://yui.yahooapis.com/combo?3.1.1/build/yui/yui-min.js&amp;3.1.1/build/oop/oop-min.js&amp;3.1.1/build/event-custom/event-custom-base-min.js&amp;3.1.1/build/event/event-base-min.js&amp;3.1.1/build/json/json-parse-min.js&amp;3.1.1/build/querystring/querystring-stringify-simple-min.js&amp;3.1.1/build/io/io-base-min.js&amp;3.1.1/build/dom/dom-base-min.js&amp;3.1.1/build/dom/selector-native-min.js&amp;3.1.1/build/dom/selector-css2-min.js&amp;3.1.1/build/node/node-base-min.js&amp;3.1.1/build/node/node-style-min.js&amp;3.1.1/build/stylesheet/stylesheet-min.js&amp;2in3.1/2.8.0/build/yui2-calendar/yui2-calendar-min.js&amp;2in3.1/2.8.0/build/yui2-yahoo/yui2-yahoo-min.js&amp;2in3.1/2.8.0/build/yui2-dom/yui2-dom-min.js&amp;2in3.1/2.8.0/build/yui2-event/yui2-event-min.js"></script> <script type="text/javascript">//<![CDATA[ YUI().use('yui2-calendar', function(Y) { var YAHOO = Y.YUI2; var cal = new YAHOO.widget.Calendar("cal",{navigator:true,mindate:'1/1/2000'); cal.render(); // ... Edit: I want to make a few minor changes to the default sam skin. What is the best way to do that? I answered this part of my question. If I wrap the calendar in an extra div, then specifying CSS rules which include that div as part of the selector makes the rule more specific so the browser uses it over Sam's skin. Rough example: <style type="text/css"> .magic .yui-skin-sam .yui-calendar td.calcell { height: 10em; width: 15em; } </style> ... <div class="magic"> <div class="yui-skin-sam"> <div id="cal"></div> </div> </div>
