  • Responsive: two different toggles on same element

    - by Mathijs Delva
    I'm having difficulties with the following problem. For a responsive website, i need to use the same toggle element for both a toggle system for one window width, and another toggle system for a second window width. I have the following snippets: 1.A simple hover for a language dropdown, which should be executed for resolutions greater than 980px. $('#clickme').hover(function() { $(this).parent().find("#select-language").show(); $(this).find("> a span").css({"opacity":"0.5"}); }, function() { $(this).parent().find("#select-language").hide(); $(this).find("> a span").css({"opacity":"1"}); }); 2.A simple click for the same language toggle, which should be executed for resolutions smaller than 980px. jQuery('#clickme').click(function() { jQuery("#select-language-mobile").slideToggle("fast"); }); I need to nest these two, so that when the user is viewing the website in one resolution, the click function with be fired, and in the other case the hover function. Can anybody help me with this? PS: I'm sorry, but the code blocks don't seem to work at the moment.

  • Is starting to use CDATA a breaking change?

    - by kicsit
    For interaction with a customer's application we use XML documents. That is, we send an XML over HTTP and receive a response XML document the same way. The customer specified two XML schemata that describe the format of both the request and reply. All was working fine, until one day the customer started to use CDATA sections in the response XML. We set up our parser unmindful of CDATA sections, so we failed to interpret them. My question is: Who made a mistake here? I tried to find an answer in the XML standards, but I'm still not sure. I think I cannot prescribe using or not using CDATA's in an XSD, is that right? If so, is it not enough to agree upon an XSD, but a separate agreement has to be made about CDATA sections? Or one is obliged to be prepared to parse CDATA and regular text as well? I'm interested in both your personal views and official statements too. Thank you!

  • Beginner having difficulty with SQL query

    - by Vulcanizer
    Hi, I've been studying SQL for 2 weeks now and I'm preparing for an SQL test. Anyway I'm trying to do this question: For the table: 1 create table data { 2 id int, 3 n1 int not null, 4 n2 int not null, 5 n3 int not null, 6 n4 int not null, 7 primary key (id) 8 } I need to return the relation with tuples (n1, n2, n3) where all the corresponding values for n4 are 0. The problem asks me to solve it WITHOUT using subqueries(nested selects/views) It also gives me an example table and the expected output from my query: 01 insert into data (id, n1, n2, n3, n4) 02 values (1, 2,4,7,0), 03 (2, 2,4,7,0), 04 (3, 3,6,9,8), 05 (4, 1,1,2,1), 06 (5, 1,1,2,0), 07 (6, 1,1,2,0), 08 (7, 5,3,8,0), 09 (8, 5,3,8,0), 10 (9, 5,3,8,0); expects (2,4,7) (5,3,8) and not (1,1,2) since that has a 1 in n4 in one of the cases. The best I could come up with was: 1 SELECT DISTINCT n1, n2, n3 2 FROM data a, data b 3 WHERE a.ID <> b.ID 4 AND a.n1 = b.n1 5 AND a.n2 = b.n2 6 AND a.n3 = b.n3 7 AND a.n4 = b.n4 8 AND a.n4 = 0 but I found out that also prints (1,1,2) since in the example (1,1,2,0) happens twice from IDs 5 and 6. Any suggestions would be really appreciated.

  • (Android) Why won't invalidate() update my buttons immediately?

    - by frustrated user
    I have read several forums and examples on using invalidate() in order to update views immediately but I still do not understand why what I am doing will not work. The code below uses image buttons defined by "red", "blue", "green", and "yellow". I set a 1 second delay between each time I try and change a button's appearance. Please someone tell me what i'm doing wrong. private void showPattern() { if (correct == true) { for (int k = 0; k < temp_basket.length; k++) { if (temp_basket[k] == 0) { red.setPressed(true); red.invalidate(); final Handler handler = new Handler(); Timer t = new Timer(); t.schedule(new TimerTask() { public void run() { handler.post(new Runnable() { public void run() { red.setPressed(false); red.invalidate(); } }); } }, 1000); There are 3 more or these blocks after this one that are blue, green, and yellow.

  • Android onFling not responding

    - by Kevin Moore
    I am new to android first of all so think of any newbie mistakes first I am trying to add a fling function in my code. public class MainGamePanel extends SurfaceView implements SurfaceHolder.Callback, OnGestureListener { private MainThread thread; private Droid droid; private Droid droid2; private static final String TAG = gameView.class.getSimpleName(); private GestureDetector gestureScanner; public MainGamePanel(Context context){ super(context); getHolder().addCallback(this); droid = new Droid(BitmapFactory.decodeResource(getResources(), R.drawable.playerbox2), 270, 300); droid2 = new Droid(BitmapFactory.decodeResource(getResources(), R.drawable.playerbox2), 50, 300); thread = new MainThread(getHolder(), this); setFocusable(true); gestureScanner = new GestureDetector(this); } public boolean onTouchEvent(MotionEvent event){ return gestureScanner.onTouchEvent(event); } @Override protected void onDraw(Canvas canvas){ canvas.drawColor(Color.BLACK); droid.draw(canvas); droid2.draw(canvas); } @Override public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) { droid.setX(50); droid.setY(50); Log.d(TAG, "Coords: x=" + e1.getX() + ",y=" + e2.getY()); return true; } @Override public boolean onDown(MotionEvent e) { droid2.setX((int)e.getX()); droid2.setY((int)e.getY()); Log.d(TAG, "Coords: x=" + e.getX() + ",y=" + e.getY()); return false; } I got the gestureListener to work with: onDown, onLongPress, and onShowPress. But i can't get any response with onFling, onSingleTapUp, and onScroll. What mistake am I making? does it have to do with views? I don't know what code would be useful to see.... so any suggestions would be much appreciated. Thank You!

  • issue with tab bar view displaying a compound view

    - by ambertch
    I created a tab bar application, and I make the first tab a table. So I create a tableView controller, and go about setting the class identity of the view controller for the first tab to my tableView controller. This works fine, and I see the contents of the table filling up the whole screen. However, this is not what I actually want in the end goal - I would like a compound window having multiple views: - the aforementioned table - a custom view with data in it So what I do is create a nib for this content (call it contentNib), change the tab's class from the tableView controller to a generic UIViewController, and set the nib of that tab to this new contentNib. In this new contentNib I drag on a tableView and set File's Owner to the TableViewController. I then link the dataSource and delegate to file's owner (which is TableViewController). Surprisingly this does not work and I receive the error: **Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[UIViewController tableView:numberOfRowsInSection:]: unrecognized selector sent to instance 0x3b0f910'** This is bewildering to me since the file's owner is the TableViewController, which has been assigned to be both the dataSource and delegate. Does someone have either insight into my confusions, or a link to an example of how to have a compound view include a tableView? *update* I see this in the Apple TableView programming guide: "Note: You should use a UIViewController subclass rather than a subclass of UITableViewController to manage a table view if the view to be managed is composed of multiple subviews, one of which is a table view. The default behavior of the UITableViewController class is to make the table view fill the screen between the navigation bar and the tab bar (if either are present)." <----- I don't really get what this is telling me to do though... if someone can explain or point me to an example I'd be much appreciated!

  • Changing style sheets depending on useragent

    - by John Vasiliou
    <script language="Javascript"> var deviceIphone = "iPhone"; var deviceIpod = "iPod"; //Initialize our user agent string to lower case. var uagent = navigator.userAgent.toLowerCase(); //************************** // Detects if the current device is an iPhone. function DetectiPhone() { if (uagent.search(deviceIphone) > -1) {document.write('<link rel="stylesheet" type="text/css" href="ui/mobile/css/site.css">'); } etc... Above is the start of my code. I am trying to change the CSS file depending on what platform the user is using. I currently use media="screen ... " but it doesn't work with the amount of platforms I'm trying to use. I need something a lot more detailed/complex that is why I'm turning to useragents. Any ideas why the css file doesn't change on my iPhone using the above code? Better yet, any ideas on another way to change style sheets depending on the users platform/screen resolution?

  • One-to-many Associations Empty Columns Issue (Ext on Rails)

    - by Joe
    I'm playing with rewriting part of a web application in Rails + Ext. However, I'm having trouble getting an associated models' name to display in the grid view. I've been able to successfully convert several models and arrange the views nicely using tabs and Ext's layout helpers. However, I'm in the middle of setting up an association -- I've followed along with Jon Barket's tutorial on how to do this using Ext -- and I've made all the Rails and JS changes suggested (with appropriate name changes for my models,) the result being that the combo box is now being correctly populated with the names of the associated models, and changes are actually written correctly to database, BUT the data doesn't show up in the column, it's just empty. However, the correct data is there in the 'detail' view. Really just wondering if anyone else ran into this, or had any thoughts on what could be happening. Definitely willing to post code if requested; just note that (AFAIK) my changes follow the tutorial pretty closely. Thanks in advance! UPDATE: Alright, slight progress - kind of. I can get the associated model id # displaying properly -- just by modifying the column model slightly. But I can't get the virtual attribute displayed in the main table (in Jon's example it's country_name.) It still goes blank when I change the data source for that column from dataIndex: 'model[associated_model_id]' to dataIndex: 'virtual_attributes[associated_model_name]' ANOTHER UPDATE: Bump. Has NOBODY here tried integrating Ext with Rails?

  • javascript unable to locate a form using the ID tag

    - by ihake
    Here's my problem: I'm trying to set up a simple mobile contact form with a captcha built in. The page I'm working on can be found here: http://m.lancasterpainting.com/contact.php I'm using the following php contact form: http://www.html-form-guide.com/contact-form/php-email-contact-form.html I want to first say that I'm not the only one to run into this problem. After googling the issue, I've found multiple people struggling with this, but no-one seems to have an answer. Now for the problem... As you can see if you visit the page, each time the page is accessed, an error appears that says "Error: couldnot get Form object contact_form". I cannot--for the life of me--figure out why the javascript can't find the form I pass it. I call the function that generates this error at the top of the page: var frmvalidator = new Validator("contact_form"); The form I'm referencing is as follows in the HTML code: <div data-role="page" data-theme="e" id="contact_form" name="contact_form" data-position="inline"> ... And the function that is called that generates the error can be found in an external .js file here: http://m.lancasterpainting.com/scripts/gen_validatorv31.js Is there something that I am simply not seeing? Why can't the javascript locate the form? Thanks so much to anyone that helps with this.

  • How do I change the application background color at run-time in a Flex 3.5 application?

    - by Adam Tuttle
    I have a Flex 3.5 application that will serve multiple purposes, and as part of the visual changes that I'd like to make to indicate which mode the application is in, I want to change its background color. Currently, the application tag looks like this: <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" xmlns:com="ventures.view.component.*" xmlns:views="ventures.view.*" layout="absolute" preinitialize="onPreInitialize()" creationComplete="onCreationComplete()" applicationComplete="onApplicationComplete()" click="onClick(event)" enabled="{(!chainController.generalLocked)}" backgroundGradientColors="[0xFFFFFF, 0xFFFFFF]" > I've tried using a binding, for both the backgroundColor and backgroundGradientColors attributes: <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" ... backgroundColor="{app_background_color}" > —and— <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" ... backgroundGradientColors="{app_background_color}" > but for the former binding is not allowed, and for the latter there is a warning that: Data binding will not be able to detect assignments to "app_background_color". I also ran across this page which seems to indicate that I could do it with the setStyle() method, but the documentation seems to indicate that this method is only available for components, not the main canvas. I suppose I could wrap everything in a <mx:Canvas></mx:Canvas> specificially for this purpose, but that seems wasteful—like Div-itis in HTML or something. What's the best way to change the main application background color at run-time?

  • What's your take on this Javascript thingy?

    - by Nischal
    We've been having a discussion at our workplace on this with some for and some against the behavior. Wanted to hear views from you guys : <html> <body> <div> Test! <script> document.body.removeChild(document.getElementsByTagName('div')[0]); </script> </div> </body> </html> Should the above script work and do what it's supposed to do? First, let's see what's happening here : I have a javascript that's inside the <div> element. This javascript will delete the child node within body which happens to hold the div inside which the script itself exists. Now, the above script works fine in Firefox, Opera and IE8. But IE6 and IE7 give an alert saying they cannot open the page. Let's not debate on how IE should have handled this (they've accepted it as a bug and hence fixed it in IE8). The point here is since the 'SCRIPT' tag itself is a part of DOM, should it be allowed to do something like this? Should it even exist after such an operation?

  • Google Anlytics event not firing

    - by yar1
    I am not getting and event data in GA. I installed Google Analytics Debugger Chrome extension and I see nothing happening (same goes when looking at Network panel in developer tools). I Googled it and read many (many) other answers and it looks like I'm doing things right. Page views, etc. are registering correctly... I have this code as the last thing before my closing tag: <script> (function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){ (i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o), m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m) })(window,document,'script','//www.google-analytics.com/analytics.js','ga'); ga('create', 'UA-MYREALCODE', 'mybna.net'); ga('send', 'pageview'); var _gaq = _gaq || []; _gaq.push(['_setAccount', 'UA-MYREALCODE']); _gaq.push(['_trackPageview']); </script> My event handlers are done using jQuery, all inside an external js file, loaded before the closing tag. For example: $(function () { $('#show-less').click(function (e) { pbr.showHideMore(e); _gaq.push(['_trackEvent', 'ShowMore', 'Hide', 'top button']); }); }); Any ideas anyone?

  • NSView only redraws on breakpoint

    - by Jacopo
    I have a custom view inside a NSPopover. It should change according to user input and it does the first time the user interact with it but it fails to redraw the following times. I have tried to put an NSLog inside the -drawRect: method and it doesn't get called during normal execution. When I try to debug and put a breakpoint inside the method it gets called normally and the app works as it should. I explicitly call the view -setNeedsDisplay: method every time I need it to redraw. I don't understand why it should make a difference. Here is the code that update the status of the view. These methods are part of the NSTextField delegate method -textDidChange: and I checked that these get called every time the user type something in the textfield associated with popover. [tokenCloud tokensToHighlight:[NSArray arrayWithObject:completeSuggestionString]]; tokenCloud.tokens = filteredTokens; [tokenCloud setNeedsDisplay:YES]; The views is a series of recessed button. The first line update the status of all the buttons in the popover and the second add or delete buttons. They both work properly because the first time they are called the view is update properly. I have also checked that both the status of the buttons in tokenCloud and its property tokens are updated correctly. The problem is that the NSView subclass, tokenCloud, doesn't redraw so the changes are not reflected in the UI the second time. Here is the draw method of the view: - (void)drawRect:(NSRect)rect { [self recalculateButtonLocations]; NSLog(@"Redrawn"); } Again this method gets called normally every time I update the view if I place a breakpoint in [self recalculateButtonLocations];. If instead I let the app run normally nothing gets logged in the console the second time I update the view. Same thing if I include the NSLog in the recalculateButtonLocations method, nothing gets logged the second time meaning that the method is not called.

  • Domain model for an online WYSYWG webpage generator / runtime

    - by CharlieBrown
    Hi all, I'm using C#, MVC, NHibernate and StructureMap as my IoC container, and need some ideas regarding my domain model. The application I'm working has two parts: an Authoring part and a Runtime part. The idea is to allow the user to create a webpage in Authoring (mostly a form actually) by choosing from a set of predefined controls. That webpage will be later used as a form in a call center environment (Runtime part), or may be used in an intranet portal, etc. Basically something similar to what a CMS would do. The difference is, of course, that the webpage/form the author generates will be used and fulfilled in runtime, and that authros should be able to freely create the webpage they want without limitations. I have a draft working model that allows a RunController to iterate over the ScriptPage (my class for the "generated webpage") Controls collection and uses partial views to render each of them. Works kind of fine. Basically I have a common ScriptControl class, and then I can create for example a TextInputControl or a DropDownControl by inheriting from that base class. I can also figure out the Authoring part of the app, although that will surely be fun in itself for sure. :) The biggest problem I have now is persistance. In order to be flexible, I want to be able to add more controls, and template controls (think of an Address composite control) in sepparate DLLs, so I think having a relational model that handles very possible control is not the way to go. My current thinking is using a kind of ObjectStore: binary-serializing the ScriptPage object that contains the List collection and deserializing at Runtime, but I'm not sure how good will it work with NHibernate and how good the performance will be. Serializing a small "page" with 10 controls results in 7964 bytes, for example. Any ideas out there? Thanks in advance, excuse the length. ;)

  • What are various methods for discovering test cases

    - by NativeByte
    All, I am a developer but like to know more about testing process and methods. I believe this helps me write more solid code as it improves the cases I can test using my unit tests before delivering product to the test team. I have recently started looking at Test Driven Development and Exploratory testing approach to software projects. Now it's easier for me to find test cases for the code that I have written. But I am curios to know how to discover test cases when I am not the developer for the functionality under test. Say for e.g. let's have a basic user registration form that we see on various websites. Assuming the person testing it is not the developer of the form, how should one go about testing the input fields on the form, what would be your strategy? How would you discover test cases? I believe this kind of testing benefits from exploratory testing approach, i may be wrong here though. I would appreciate your views on this. Thanks, Byte

  • Best way and problems when using ajax tabs with an MVC PHP project

    - by Jonathan
    Hi, I'm building an IMDB.com like website using PHP/jQuery and a MVC approach (no OOP). I have an index.php base controller to 'rule them all' :), a controllers folder with all the controllers, a models folder and a view folder. In some pages of the website I have tabbed navigation, when the visitor clicks on one of those tabs to get more information, jQuery gets that data using the $.post or $.get method and shows it on the tab container, obviously without refreshing the page. The problem is that those pages loaded by ajax are also generated using controllers, models, and views, and the things are getting a bit complicated for someone like me ( = 'no experience'). To dynamically get the data I some times need to include a model twice, include an include in an include in an include, send information multiple times, connect with the database again, and all sort of things like that and I'm sure there is a better and prettier way to do this. I'm searching for the best approach and common methods for this. I have no experience working with a big project like this. This is a personal project so I have full control and every answer is welcome. Thanks!!!

  • Why would 1.000 subforms in a db be a bad idea?

    - by KlaymenDK
    Warm-up I'm trying to come up with a good way to implement customized document forms. It's for a tool to request access to applications; each application will want to ask its own specific questions. The thing is, we have one kind of (common) user who needs to fill in and submit documents based on templates, and another kind of (super) user who needs to be able to define what each template needs to contain. One implementation option would be to use a form (with the basic mandatory stuff), and have that form dynamically include a subform appropriate to the specific task at hand. The gist of the matter is that we could (=will!) quite easily end up having many hundreds of different subforms! (NB. These subforms will be maintained in an automated manner, but that is another topic that may be considered outside the scope of this Question.) Question It's common knowledge that having a lot of views in a Notes database is Bad Thing. But has anyone tried pushing the number of forms or subforms and made any experiences regarding performance?

  • C# - Is it possible to start my project with a class instead of a form?

    - by Irro
    I want my project to be started through an class instead of a form, is there any way to do this? Or to be more precise is there any good way to make sure that the first class, except Program, that is started isn't a form-class. I tried to change to my class in Program.main() but it looks like Application.run() needs a ApplicationContext. I guess that I could change the Program-class to start another class and let that class start the form with Application.run() but I think that it will cause a lot of problem since I don't want the same form to be started first each time and Application.run() have to be used at least once and at most once. So I think it will be hard to keep track of if Application.run() has been used or not. Another question that might be even more important; Is this a good way to do things in .net? The reason I want to do so is because I want to create some sort of MVC project where the class I want to start with is the controller and all forms I'll use will be views.

  • sortable list using jquery ui not passing updated list order

    I am following the sortable lists railscast and got everything working except when I sort, the same (original) order gets passed to the update method each time, so it doesn't update the true order. Here's the code: In the view: %tbody#lineup{"data-update-url" => sort_lineups_url} - @lineup.pieces.each_with_index do |piece, index| = content_tag_for :tr, piece do = render 'piece', :piece => piece, :index => index and pieces.js.coffee: jQuery -> $('#lineup').sortable( axis: 'y' update: -> $.post($(this).data('update-url'), $(this).sortable('serialize')) ); sort and show methods of lineupscontroller: def show @lineup = Lineup.find_by_user_id(current_user.id) @pieces = @lineup.pieces.order("position") end def sort params[:piece].each_with_index do |id, index| current_user.lineup.pieces.update_all({position: index+1}, {id: id}) end render nothing: true end and the update request: Started POST "/lineups/sort" for 127.0.0.1 at 2012-06-24 20:06:14 -0700 Processing by LineupsController#sort as */* Parameters: {"piece"=>["8", "2", "1", "4", "3", "7"]} User Load (0.4ms) SELECT `users`.* FROM `users` WHERE `users`.`id` = 2 LIMIT 1 Lineup Load (0.6ms) SELECT `lineups`.* FROM `lineups` WHERE `lineups`.`user_id` = 2 LIMIT 1 SQL (2.9ms) UPDATE `pieces` INNER JOIN `piece_lineups` ON `pieces`.`id` = `piece_lineups`.`piece_id` SET `position` = 1 WHERE `piece_lineups`.`lineup_id` = 3 AND `pieces`.`id` = 8 SQL (0.6ms) UPDATE `pieces` INNER JOIN `piece_lineups` ON `pieces`.`id` = `piece_lineups`.`piece_id` SET `position` = 2 WHERE `piece_lineups`.`lineup_id` = 3 AND `pieces`.`id` = 2 SQL (0.6ms) UPDATE `pieces` INNER JOIN `piece_lineups` ON `pieces`.`id` = `piece_lineups`.`piece_id` SET `position` = 3 WHERE `piece_lineups`.`lineup_id` = 3 AND `pieces`.`id` = 1 SQL (0.5ms) UPDATE `pieces` INNER JOIN `piece_lineups` ON `pieces`.`id` = `piece_lineups`.`piece_id` SET `position` = 4 WHERE `piece_lineups`.`lineup_id` = 3 AND `pieces`.`id` = 4 SQL (0.6ms) UPDATE `pieces` INNER JOIN `piece_lineups` ON `pieces`.`id` = `piece_lineups`.`piece_id` SET `position` = 5 WHERE `piece_lineups`.`lineup_id` = 3 AND `pieces`.`id` = 3 SQL (0.5ms) UPDATE `pieces` INNER JOIN `piece_lineups` ON `pieces`.`id` = `piece_lineups`.`piece_id` SET `position` = 6 WHERE `piece_lineups`.`lineup_id` = 3 AND `pieces`.`id` = 7 Rendered text template (0.0ms) so each time i drag+drop the list, it sends the same order again. what am I doing wrong that the params isn't passing the right, updated order? Completed 200 OK in 2757ms (Views: 1.0ms | ActiveRecord: 6.7ms)

  • Seeking good practice advice: multisite in Drupal

    - by deanloh
    I'm using multisite to host my client sites. During development stage, I use subdomain to host the staging site, e.g. client1.mydomain.com. And here's how it look under the SITES folder: /sites/client1.mydomain.com When the site is completed and ready to go live, I created another folder for the actual domain, e.g. client1.com. Hence: /sites/client1.com Next, I created symlinks under client1.com for FILES and SETTINGS.PHP that points to the subdomain i.e. /sites/client1.com/settings.php --> /sites/client1.mydomain.com/settings.php /sites/client1.com/files --> /sites/client1.mydomain.com/files Finally, to prevent Google from indexing both the subdomain and actual domain, I created the rule in .htaccess to rewrite client1.mydomain.com to client1.com, therefore, should anyone try to access the subdomain, he will be redirected to the actual domain. This above arrangement works perfectly fine. But I somehow feel there is a better way to achieve the above in much simplified manner. Please feel free to share your views and all advice is much appreciated.

  • Need help optimizing this Django aggregate query

    - by Chris Lawlor
    I have the following model class Plugin(models.Model): name = models.CharField(max_length=50) # more fields which represents a plugin that can be downloaded from my site. To track downloads, I have class Download(models.Model): plugin = models.ForiegnKey(Plugin) timestamp = models.DateTimeField(auto_now=True) So to build a view showing plugins sorted by downloads, I have the following query: # pbd is plugins by download - commented here to prevent scrolling pbd = Plugin.objects.annotate(dl_total=Count('download')).order_by('-dl_total') Which works, but is very slow. With only 1,000 plugins, the avg. response is 3.6 - 3.9 seconds (devserver with local PostgreSQL db), where a similar view with a much simpler query (sorting by plugin release date) takes 160 ms or so. I'm looking for suggestions on how to optimize this query. I'd really prefer that the query return Plugin objects (as opposed to using values) since I'm sharing the same template for the other views (Plugins by rating, Plugins by release date, etc.), so the template is expecting Plugin objects - plus I'm not sure how I would get things like the absolute_url without a reference to the plugin object. Or, is my whole approach doomed to failure? Is there a better way to track downloads? I ultimately want to provide users some nice download statistics for the plugins they've uploaded - like downloads per day/week/month. Will I have to calculate and cache Downloads at some point? EDIT: In my test dataset, there are somewhere between 10-20 Download instances per Plugin - in production I expect this number would be much higher for many of the plugins.

  • Limiting a search to records from last_request_at...

    - by bgadoci
    I am trying to figure out how to display a count for records that have been created in a table since the last_request_at of a user. In my view I am counting the notes of a question with the following code: <% unless @questions.empty? %> <% @questions.each do |question| %> <%= h(question.notes.count) %> end end This is happening in the /views/users/show.html.erb file. Instead of counting all the notes for the question, I would only like to count the notes that have been created since the users last_request_at datetime. I don't neccessarily want to scope notes to display this 'new notes' count application wide, just simply in this one instance. To accomplish I am assuming I need to create a variable in the User#show action and call it in the view but not really sure how to do that. Other information you may need: class Note < ActiveRecord::Base belongs_to :user belongs_to :question end class Question < ActiveRecord::Base has_many :notes, :dependent => :destroy belongs_to :user end

  • Rails - Update a single attribute : link with custom action or form with hidden fields?

    - by MrRuru
    Let's say I have a User model, with a facebook_uid field corresponding to the user's facebook id. I want to allow the user to unlink his facebook account. Do do so, I need to set this attribute to nil. I currently see 2 ways of doing this First way : create a custom action and link to it # app/controllers/users_controller.rb def unlink_facebook_account @user = User.find params[:id] # Authorization checks go here @user.facebook_uid = nil @user.save # Redirection go here end # config/routes.rb ressources :users do get 'unlink_fb', :on => :member, :as => unlink_fb end # in a view = link_to "Unlink your facebook account", unlink_fb_path(@user) Second way : create a form to the existing update action # app/views/user/_unlink_fb_form.html.haml = form_for @user, :method => "post" do |f| = f.hidden_field :facebook_uid, :value => nil = f.submit "Unlink Facebook account" I'm not a big fan of either way. In the first one, I have to add a new action for something that the update controller already can do. In the second one, I cannot set the facebook_uid to nil without customizing the update action, and I cannot have a link instead of a button without adding some javascript. Still, what would you recommend as the best and most elegant solution for this context? Did I miss a third alternative?
