  • 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.

  • How do I call C++/CLI (.NET) DLLs from standard, unmanaged non-.NET applications?

    - by tronjohnson
    In the unmanaged world, I was able to write a __declspec(dllexport) or, alternatively, use a .DEF file to expose a function to be able to call a DLL. (Because of name mangling in C++ for the __stdcall, I put aliases into the .DEF file so certain applications could re-use certain exported DLL functions.) Now, I am interested in being able to expose a single entry-point function from a .NET assembly, in unmanaged-fashion, but have it enter into .NET-style functions within the DLL. Is this possible, in a simple and straight-forward fashion? What I have is a third-party program that I have extended through DLLs (plugins) that implement some complex mathematics. However, the third-party program has no means for me to visualize the calculations. I want to somehow take these pre-written math functions, compile them into a separate DLL (but using C++/CLI in .NET), but then add hooks to the functions so I can render what's going on under the hood in a .NET user control. I'm not sure how to blend the .NET stuff with the unmanaged stuff, or what to Google to accomplish this task. Specific suggestions with regard to the managed/unmanaged bridge, or alternative methods to accomplish the rendering in the manner I have described would be helpful. Thank you.

  • Sliding div in jquery

    - by Sean
    I am trying to make a toolbar type section on the top of my site. I just need one div that will be hidden by default, and a button that will be hanging off the bottom of that div. When it is clicked, the div should slide down (with the button still on bottom). And upon clicking, it should slide back up. Here is what I currently have: <div id="account_toolbar" style="background-color:#fff;"> <div id="toolbar_contents" style="display:none;"> This is the account toolbar so far </div> <div id="button" style="background-color: #ff0000;"><%= image_tag "templates/_global/my_account.png", :id => "my_account_btn", :style => "float: right; margin-right: 100px;" %></div> </div> The image tag is using ruby/rails syntax, so pay no attention to that. It will render like any other image tag. Here is the jquery i'm using: $('#my_account_btn').click(function () { $('#toolbar_contents').slideToggle(); }); So, this is actually working for the most part. My problem however is that the spacing where the toolbar content div goes, pushes the account button down. When it slides up or down it temporarily attaches itself to the bottom of the div, then jumps back down once it is finished sliding (leaving a gap between the bottom of the hidden div and the top of the account button). I hope that makes sense. thanks

  • fastest public web app framework for quick DB apps?

    - by Steve Eisner
    I'd like to pick up a new tech for my toolbox - something for rapid prototyping of web apps. Brief requirements: public access (not hosted on my machine) - like Google's appengine, etc no tricky configuration necessary to build a simple web app host DB access (small storage provided) including some kind of SQLish query language easy front end HTML templating ability to access as a JSON service C# or Java,PHP or Python - or a fun new language to learn is OK free! An example app, very simple: render an AJAXy editable (add/delete/edit/drag) list of rich-data list items via some template language, so I can quickly mock up a UI for a client. ie. I can do most of the work client-side, but need convenient back end to handle the permanent storage. (In fact I suppose it doesn't even need HTML templating if I can directly access a DB via AJAX calls.) I realize this is a bit vague but am wondering if anyone has recommendations. A Rails host might be best for this (but probably not free) or maybe App Engine, or some other choice I'm not aware of? I've been doing everything with heavyweight servers (ASP.NET etc) for so long that I'm just not up on the latest... Thanks - I'll follow up on comments if this isn't clear enough :)

  • Picture.writeToStream() not writing out all bitmaps

    - by quickdraw mcgraw
    I'm using webview.capturePicture() to create a Picture object that contains all the drawing objects for a webpage. I can successfully render this Picture object to a bitmap using the canvas.drawPicture(picture, dst) with no problems. However when I use picture.writeToStream(fos) to serialize the picture object out to file, and then Picture.createFromStream(fis) to read the data back in and create a new picture object, the resultant bitmap when rendered as above is missing any larger images (anything over around 20KB! by observation). This occurs on all the Android OS platforms that I have tested 1.5, 1.6 and 2.1. Looking at the native code for Skia which is the underlying Android graphics library and the output file produced from the picture.writeToStream() I can see how the file format is constructed. I can see that some of the images in this Skia spool file are not being written out (the larger ones), the code that appears to be the problem is in skBitmap.cpp in the method void SkBitmap::flatten(SkFlattenableWriteBuffer& buffer) const; It writes out the bitmap fWidth, fHeight, fRowBytes, FConfig and isOpaque values but then just writes out SERIALIZE_PIXELTYPE_NONE (0). This means that the spool file does not contain any pixel information about the actual image and therefore cannot restore the picture object correctly. Effectively this renders the writeToStream and createFromStream() APIs useless as they do not reliably store and recreate the picture data. Has anybody else seen this behaviour and if so am I using the API incorrectly, can it be worked around, is there an explanation i.e. incomplete API / bug and if so are there any plans for a fix in a future release of Android? Thanks in advance.

  • dotNet Templated, Repeating, Databound ServerControl: Counting the templates OnDataBind?

    - by Campbeln
    I have a server control that wraps an underlying class which manages a number of indexes to track where it is in a dataset (ie: RenderedRecordCount, ErroredRecordCount, NewRecordCount, etc.). I've got the server control rendering great, but OnDataBinding I'm having an issue as to seems to happen after CreateChildControls and before Render (both of which properly manage the iteration of the underlying indexes). While I'm somewhat familiar with the ASP.NET page lifecycle, this one seems to be beyond me at the moment. So... how do I hook into the iterative process OnDataBinding uses so I can manage the underlying indexes? Will I have to iterate over the ITemplates myself, managing the indexes as I go or is there an easier solution? Also... I implemented the iteration of the underlying indexes during CreateChildControls originally in the belief that was the proper place to hook in for events like OnDataBinding (thining it was done as the controls were being .Add'd). Now it seems that this may actually be unnecessary. So I guess the secondary question is: What happens during CreateChildControls? Are the unadulterated (read: with <%-tags in place) controls added to the .Controls collection without any other processing?

  • Is there a way to update the height of a single UITableViewCell, without recalculating the height for every cell?

    - by Chris Vasselli
    I have a UITableView with a few different sections. One section contains cells that will resize as a user types text into a UITextView. Another section contains cells that render HTML content, for which calculating the height is relatively expensive. Right now when the user types into the UITextView, in order to get the table view to update the height of the cell, I call [self.tableView beginUpdates]; [self.tableView endUpdates]; However, this causes the table to recalculate the height of every cell in the table, when I really only need to update the single cell that was typed into. Not only that, but instead of recalculating the estimated height using tableView:estimatedHeightForRowAtIndexPath:, it calls tableView:heightForRowAtIndexPath: for every cell, even those not being displayed. Is there any way to ask the table view to update just the height of a single cell, without doing all of this unnecessary work? Update I'm still looking for a solution to this. As suggested, I've tried using reloadRowsAtIndexPaths:, but it doesn't look like this will work. Calling reloadRowsAtIndexPaths: with even a single row will still cause heightForRowAtIndexPath: to be called for every row, even though cellForRowAtIndexPath: will only be called for the row you requested. In fact, it looks like any time a row is inserted, deleted, or reloaded, heightForRowAtIndexPath: is called for every row in the table cell. I've also tried putting code in willDisplayCell:forRowAtIndexPath: to calculate the height just before a cell is going to appear. In order for this to work, I would need to force the table view to re-request the height for the row after I do the calculation. Unfortunately, calling [self.tableView beginUpdates]; [self.tableView endUpdates]; from willDisplayCell:forRowAtIndexPath: causes an index out of bounds exception deep in UITableView's internal code. I guess they don't expect us to do this. I can't help but feel like it's a bug in the SDK that in response to [self.tableView endUpdates] it doesn't call estimatedHeightForRowAtIndexPath: for cells that aren't visible, but I'm still trying to find some kind of workaround. Any help is appreciated.

  • Defining Views Based On Selection

    - by Wayne
    Well the title isn't very descriptive but I'm not exactly sure how to explain but here goes! I have a web application (can use either MVC or standard web forms) which a user signs in to. If the user has signed up for more than one product they will have the option to switch between them. For the sakes of this example lets say User1 signs in and has access to Product1, Product2 and Product3. Now, each product will be very different and offer different functionally. What I want is the main view to be focused around the product they have selected and not redirected to a sub domain. What I don't want to have to do is get them to go to www.mysite.com/product1 or www.mysite.com/product2 but simply www.mysite.com regardless of the product they have selected and have the site render the views etc for that product. Wow does any of that make any sense? I was thinking mabe the use of sessions or something and URL rewriting? Are there any sample apps out there that make use of the same kind of functionallity that I could take a look at? Thanks for any help I appreciate it!

  • OOP + MVC advice on Member Controller

    - by dan727
    Hi, I am trying to follow good practices as much as possible while I'm learning using OOP in an MVC structure, so i'm turning to you guys for a bit of advice on something which is bothering me a little here. I am writing a site where I will have a number of different forms for members to fill in (mainly data about themselves), so i've decided to set up a Member controller where all of the forms relating to the member are represented as individual methods. This includes login/logout methods, as well as editing profile data etc. In addition to these methods, i also have a method to generate the member's control panel widget, which is a constant on every page on the site while the member is logged in. The only thing is, all of the other methods in this controller all have the same dependencies and form templates, so it would be great to generate all this in the constructor, but as the control_panel method does not have the same dependencies etc, I cannot use the constructor for this purpose, and instead I have to redeclare the dependencies and same template snippets in each method. This obviously isn't ideal and doesn't follow DRY principle, but I'm wondering what I should do with the control_panel method, as it is related to the member and that's why I put it in that controller in the first place. Am I just over-complicating things here and does it make sense to just move the control_panel method into a simple helper class? Here are the basic methods of the controller: class Member_Controller extends Website_Controller { public function __construct() { parent::__construct(); if (request::is_ajax()) { $this->auto_render = FALSE; // disable auto render } } public static function control_panel() { //load control panel view $panel = new View('user/control_panel'); return $panel; } public function login() { } public function register() { } public function profile() { } public function household() { } public function edit_profile() { } public function logout() { } }

  • Facebook API - Detect if session is active OR NOT active

    - by Tom Doe
    I'm sure I'm simply overlooking something in the Facebook API docs. Basically, after I've loaded the FB Graph, I need to know if the session is active... I cannot simply assume they're logged out and simply re-render if they're logged in once the 'auth.statusChange' event is triggered. I need to know right off the bat. Below is the code that I've used. Most importantly the FB.getLoginStatus/getAuthResponse/getAccessToken don't work like I'd expect; essentially where it indicates, when invoked, whether they're logged in or out. (function(d) { // Create fb-root var fb_root = document.createElement('div'); fb_root.id = "fb-root"; document.getElementsByTagName('body')[0].appendChild( fb_root ); // Load FB Async var js, id = 'facebook-jssdk', ref = d.getElementsByTagName('script')[0]; if (d.getElementById(id)) {return;} js = d.createElement('script'); js.id = id; js.async = true; js.src = "//connect.facebook.net/en_US/all.js"; ref.parentNode.insertBefore(js, ref); // App config-data var config = { appId : XXXX, cookie: true, status: true, frictionlessRequests: true }; window.fbAsyncInit = function() { // This won't work. // I can't assume they're logged out and rely on this to tell me they're logged in. FB.Event.subscribe('auth.statusChange', function(response) {}); // Init FB.init(config); // These do not inidicate if the user is logged out :( FB.getLoginStatus(function(response) { }); FB.getAuthResponse(function(response) { }); FB.getAccessToken(function(response) { }); }; }(document)); Any help is much appreciated. :)

  • Canvas draw calls are rendering out of sequence

    - by Tom Murray
    I have the following code for writing draw calls to a "back buffer" canvas, then placing those in a main canvas using drawImage. This is for optimization purposes and to ensure all images get placed in sequence. Before placing the buffer canvas on top of the main one, I'm using fillRect to create a dark-blue background on the main canvas. However, the blue background is rendering after the sprites. This is unexpected, as I am making its fillRect call first. Here is my code: render: function() { this.buffer.clearRect(0,0,this.w,this.h); this.context.fillStyle = "#000044"; this.context.fillRect(0,0,this.w,this.h); for (var i in this.renderQueue) { for (var ii = 0; ii < this.renderQueue[i].length; ii++) { sprite = this.renderQueue[i][ii]; // Draw it! this.buffer.fillStyle = "green"; this.buffer.fillRect(sprite.x, sprite.y, sprite.w, sprite.h); } } this.context.drawImage(this.bufferCanvas,0,0); } This also happens when I use fillRect on the buffer canvas, instead of the main one. Changing the globalCompositeOperation between 'source-over' and 'destination-over' (for both contexts) does nothing to change this. Paradoxically, if I instead place the blue fillRect inside the nested for loops with the other draw calls, it works as expected... Thanks in advance!

  • Rails from with better url

    - by Sam
    wow, switching to rest is a different paradigm for sure and is mainly a headache right now. view <% form_tag (businesses_path, :method => "get") do %> <%= select_tag :business_category_id, options_for_select(@business_categories.collect {|bc| [bc.name, bc.id ]}.insert(0, ["All Containers", 0]), which_business_category(@business_category) ), { :onchange => "this.form.submit();"} %> <% end %> controller def index @business_categories = BusinessCategory.find(:all) if params[:business_category_id].to_i != 0 @business_category = BusinessCategory.find(params[:business_category_id]) @businesses = @business_category.businesses else @businesses = Business.all end respond_to do |format| format.html # index.html.erb format.xml { render :xml => @businesses } end end routes map.resources What I want to to is get a better url than what this form is presenting which is the following: http://localhost:3000/businesses?business_category_id=1 Without rest I would have do something like http://localhost:3000/business/view/bbq bbq as permalink or I would have done http://localhost:300/business_categories/view/bbq and get the business that are associated with the category but I don't really know the best way of doing this. So the two questions are what is the best logic of finding a business by its categories using the latter form and number two how to get that in a pretty url all through restful routes in rails.

  • [Rails] Accessing error_messages on form_tag

    - by aaronrussell
    I have built a custom form for creating a joining model on a has_many :through relationship. The models look roughly like this: class Team has_many :team_members has_many :members, :through => :team_members end class Member has_many :team_members has_many :teams, :through => :team_members end class TeamMember belongs_to :team belongs_to :member # and this model has some validations too end The form I have built is for selecting which members should be in a team. I won't paste the form, but it uses the form_tag method and basically sends an array of hashes which contain a member_id and a squad_number. I then update the database with an action that looks roughly like this (simplified a bit, but you get the jist): @team.transaction do @team.team_members = params[:team_members].collect{|tm| @team.team_members.new(tm)} if @team.save redirect_to ... else render :action => :members end end Everything works great but I am validating the squad_number for uniqueness and numerically. So, when any of those validations fail, how do I get access to them in my view, and how do I ascertain which of the many members it has failed on?

  • Mystery: How does Google do cross-domain iframe communication?

    - by Shraga
    Hi everyone, When you host Googles web search element on a page, a div is created which incorporates an iframe which points to a Google adsense ads page. However, if there are no ads for the specific query, Google somehow changes the class on YOUR domain to render the div (and iframe) invisible. They are NOT using postMessage, as it also works in IE7. They are also not using the fragment identifier method, as no hash appears in the url. So how do they do it? To check what I'm saying just put the following into a regular html page: <!-- Google Custom Search Element --> <div id="cse" style="width:100%;">Loading</div> <script src="http://www.google.com/jsapi" type="text/javascript"></script> <script type="text/javascript"> google.load('search', '1'); google.setOnLoadCallback(function(){ new google.search.CustomSearchControl().draw('cse'); }, true); </script> and then do a search for "cars" (or anything else that will definitely have ads) and then for "wzxv", which has no ads...

  • rails route question

    - by badnaam
    I am trying to build a search functionality which at a high level works like this. 1 - I have a Search model, controller with a search_set action and search views/partial to render the search. 2 - At the home page a serach form is loaded with an empty search object or a search object initialized with session[:search] (which contains user search preferences, zip code, proximity, sort order, per page etc). This form has a post(:put) action to search_set. 3 - When a registered user performs a set the params of the search form are collected and a search record is saved against that user. If a unregistered user performs a search then the search set action simply stores the params in the session[:search]. In either case, the search is executed with the given params and the results are displayed. At this point the url of in the location bar is something like.. http://localhost:3000/searches/search_set?stype=1 At this point if the user simply hits enter on the location bar, I get an error that says "No action responded to show" I am guessing because the URL contains search_set which uses a put method and even though I have a search_show (:get) action (which simply reruns the search in the session or saved in the database) does not get called. How can I handle this situation where I can route a user hitting enter into the location bar to a get method? If this does not explain the problem , please let me know I can share more details/code etc. Thanks!

  • Using Color.rgb() doesnt work for full 0...255 range

    - by superflyninja
    I'm writing an android game using opengl. I'm using: colour = Color.rgb(theR,theG,theB); (all ints) to store the color of a rectangle. Then I parse out the RGB to render the rectangle: colorR = Color.red(color); colorG = Color.green(color); colorB = Color.blue(color); For example for color 53,130,255 this should result in a blue but on my app it results in a white. If i use 1,1,1 i get white. If i use 0,0,0 i get black. If i use 0,1,0 I get green etc. So it looks like any value over one is treated as 1 and so i am not getting the full 0...255 range. I tried using Color.argb and color = Color.parseColor(theColor) where the Color is a string. I'm using this in an opengles app. I have a class to display a rectangle of color. This definitely works fine as the correct size rectangle is rendered, just not a color using values above 1. I also use textures and everything displays fine. any ideas? thanks a million

  • new project app; use entirely node.js

    - by Jared
    I have been looking into Node.js, express and Nowjs and love how easy it is to have real time interactions between clients. My background is mostly from CodeIgniter MVC using PHP and MYSql. I want to re make a current web project of mine from scratch to make everything better and more real time with this newer technology. After researching and doing test examples I want to use node.js , express and Nowjs for the real time interactions once someone connects to the socket.io to pull data back to clients. But use Code Igniter for the control of the site and user management , possible shopping cart/store , pretty much everything else. This is purely due to time constraints and that I am already familiar with doing it that way. I have been looking at MongoDB as an alternative to MySql, Basically the app is going to be multiple chat rooms all on one page. with the ability of notifications and private messaging. Lots of data transfer and images. before I started piecing it together I wanted to get people who have already done something similar. My model would use Code Igniter and MySQL to render the page and then connect them onto a node.js server and broadcast using express and nowjs would using a mongoDB be better than mySQL for tons of messages and data being stored or MYSQL? Also does it make since to not make the whole site on Node.js , kinda piece it together like that?

  • Accessing global variables in a flash[:notice]

    This is deals_controller.rb. And it works like this, except two things. Not sure how to call Deal.count to add in my flash[:notice] . I get the hunch that its not calling something global.

  • Dynamic Image Caching with Java

    - by zteater
    I have a servlet with an API that delivers images from GET requests. The servlet creates a data file of CAD commands based on the parameters of the GET request. This data file is then delivered to an image parser, which creates an image on the file system. The servlet reads the image and returns the bytes on the response. All of the IO and the calling of the image parser program can be very taxing and images of around 80kb are rendering in 3-4000ms on a local system. There are roughly 20 parameters that make up the GET request. Each correlates to a different portion of the image. So, the combinations of possible images is extremely large. To alleviate the loading time, I plan to store BLOBs of rendered images in a database. If a GET request matches one previously executed, I will pull from cache. Else, I will render a new one. This does not fix "first-time" run, but will help "n+1 runs". Any other ideas on how I can improve performance?

  • BlackBerry Field class extension will not paint.

    - by jlindenbaum
    Using JRE 5.0.0, simulator device is an 8520. On a screen I am using a FlowFieldManager(Manager.VERTICAL_SCROLL) and adding Fields to it to show data. When I do this.flowManager = new FlowFieldManager(Manager.VERTICAL_SCROLL); Field field = new Field() { protected void paint(Graphics graphics) { graphics.drawTest("Test", 0, 0); } protected void layout(int width, int height) { this.setExtend(300, 300); // just testing } } this.flowManager.add(field); The screen renders correctly and 'Test' appears on the screen. If, on the other hand, I try and abstract this into a class called CustomField with the same properties and add it to the flow manager the render will not happen. Debugging shows that the device enters into the Object, into the layout function, but not the paint function. I can't figure out why the paint function is not called when I extend Field. The 4.5 API says that layout and paint are the only functions that I really need to extend. (getPreferredWidth and getPreferredHeight will be used to calculate screen sizes etc.) Thanks in advance.

  • JQuery Control Update Not Happening

    - by Mad Halfling
    Hi, I've got a script that disables a button input control, empties a table body and then (after an AJAX call) re-populates it. It all works fine but sometimes there are a lot of rows in the table so the browser (IE) takes a while to empty and refill it. The strange thing is, while the rows are being emptied, the button still appears to be enabled, however if I put an alert between the button being disabled and the tbody being emptied, the button works properly, disabling visibly before the the alert comes up. Is there any way I can get the button to update before the resource consuming table emptying process/command commences? Thx MH Code sample, as requested (but it's not complex, so I didn't initially include it) $('#Search').attr('disabled', true); $('#StatusSpan').empty(); $('#DisplayTBody').empty(); then I perform my AJAX call, re-enable the button and repopulate the table. As I mentioned, normally this is really quick and isn't a problem, but if there are, say, 1500 rows in the table it takes a while to clear down but the 'Search' button doesn't update on the screen, however if I put an alert after the .attr('disabled' line the button visibly updates when the alert box is up, but without that the button doesn't visibly disable until after the table clears (which is about 3 or 4 seconds with 1500 rows), it just stays in it's down/"mid-press" state. I don't have a problem with the time the browser is taking to render the table changes, that's just life, but I need the users to see visible feedback so they know the search has started

  • jQuery validation plugin: valid() does not work with remote validation ?

    - by a-dilla
    I got started by following this awesome tutorial, but wanted to do the validation on on keyup and place my errors somewhere else. The remote validation shows its own error message at the appropriate times, making me think I had it working. But if I ask specifically if a field with remote validation is valid, it says no, actually, its not. In application.js I have this... $("#new_user").validate({ rules: { "user[login]": {required: true, minlength: 3, remote: "/live_validations/check_login"}, }, messages: { "user[login]": {required: " ", minlength: " ", remote: " "}, } }); $("#user_login").keyup(function(){ if($(this).valid()){ $(this).siblings(".feedback").html("0"); }else{ $(this).siblings(".feedback").html("1"); } }) And then this in the rails app... def check_login @user = User.find_by_login(params[:user][:login]) respond_to do |format| format.json { render :json => @user ? "false" : "true" } end end I think that my problem might have everything to do with this ticket over at jQuery, and tried to implement that code, but, being new to jQuery, it's all a bit over my head. When I say bit, I mean way way. Any ideas to fix it, or a new way to look at it, would be a big help.
