• newbie: Rails on remote Apache server not displaying index.html.erb

  - by paracaudex

  I played around with Rails on my laptop (running Linux + Apache + MySQL) and had no trouble getting the Getting Started with Rails tutorial to work locally. Now I'm trying the same thing at work on a remote Mac OS X + Apache server, and things aren't quite so rosy. I typed rails blog -d mysql to create a directory called blog in /Library/WebServer/Documents/mydirectory. The trouble is, if I go to server.com/mydirectory/public, I get the public/index.html in my browser. But, I don't get this file if I go to server.com/mydirectory/. Instead, I get a 403 error. Also, when I: script/generate controller home index to create: app/views/home/index.html.erb I am unable to view this file, whether I go to server.com/mydirectory/home/index, or if I add a new line (map.root :controller => "home") to config/routes.rb and go to server.com/mydirectory. Am I missing something really obvious about Apache and Rails?

• What was the most surprising failure of your 'Engineer's intuition'?

  - by Bubba88

  Hi! This may seem as an open-ended question but I'll surely accept the most impressive and upvoted answer ;) Basically, I could describe my own case - I just fail 5 times a day with my intuition cause very frequently I can be just not up-to-the-speed with my requirements/manager/team/etc. and I just have to make code quickly - that's why proper formalization in many cases stands aside. I want to gather some experience of yours - what was the most epic failure when you did rely on you implicit reasoning/intuitive knowledge/immediate perception etc. of course everything you describe should be related to programming/computers. It's mostly just to measure the danger of using that 'it's obvious..' words. I've made it com. wiki to be properly transformed after gathering enough views count. Thank you!

• Is this part of MVC in .NET?

  - by 4thSpace

  I have a .NET MVC winform app. I've created an AppDelegate class that handles application startup and shutdown...for now (it might do more later). Winform apps have a Program.cs file that does some app initialization, starts the message pump and creates the first form. In my app, the first form is AppDelegate, which isn't really a form but is forced that way by Application.Run(). AppDelegate does any further app initialization and starts the first Controller, which then initializes any child controllers (these then create their views). I don't consider events occuring in Program.cs and AppDelegate as part of the MVC. Conceptually, what would these be called?

• how to organize javascripts using rails and jquery

  - by VP

  Hi, i'm working in a big and rich rails web application using tons of javascript. I would like to know if anybody has a tip to organize the javascripts. Today i'm generating a new file named controller.js and adding it to my views using content_for. The problem is, some files are becoming big and sometimes, i need a function from one controller in another, so then in the end, i add a products.js to a details controller just to keep DRY. Is that solution good? Any other tip? I think the same pattern can be applied as well to css files?

• allowDefinition='MachineToApplication' error when publishing from VS2010 (but only after a previous

  - by burnt_hand

  I can run my Asp.Net MVC 2 application without an issue on my local computer. Just Run / Debug. But if I have already built it, I can't publish it! I have to clean the solution and publish it again. I know this is not system critical, but it's really annoying. "One Click Publish" is not "Clean solution and then One click publish" The exact error is as follows: Error 11 It is an error to use a section registered as allowDefinition='MachineToApplication' beyond application level. This error can be caused by a virtual directory not being configured as an application in IIS. I suspect it's something to do with the Web.Config in the Views folder, but then why only after I build once previously. And just to note, the app works fine once published.

• Rails override validator message

  - by Anand

  Hi, I have a site thats served in 2 flavours, English and French. Here's some code app/views/user/register.html.erb ----------------- <% form_for .....> <%= f.text_field :first_name %> <% end %> app/models/user.rb ------------------ class User < ActiveRecord::Base validates_presence_of :first_name end Now to display the error message in case if the site is being served in the French version, I have app/config/locales/fr.yml ------------------------- activerecord: errors: messages: empty: "ne peut pas être vide" So if someone does not fill in a first name, the validator takes the name of the field and appends the custom message for empty clause giving "First name ne peut pas être vide" which is incorrect, coz 'First name' in French is 'Prénom', hence it should be "Prénom ne peut pas être vide" Please can someone suggest a way of achieving the desired result.

• iPhone TabBar selection cancelling

  - by Chris Schnyder

  I am developing an iPhone app that displays several views, all acessed via Tab Bar items. However I need to add an additional item to the Tab Bar that simply launches a URL in Safari. I've accomplished this by adding an empty placeholder view to the TabBar and returning FALSE from shouldSelectViewController when the this view's tabBarItem is clicked on, and launching Safari at the same time. That code is: - (BOOL)tabBarController:(UITabBarController *)tabBarController shouldSelectViewController:(UIViewController *)viewController { if([[viewController tabBarItem] title] == "Website"){ //... launch Safari return FALSE; } else { return TRUE; } } PROBLEM: If the TabBar has too many items, and this "Safari Launch" tab is pushed off to the "More" navigation controller, I lose the capability to intercept the event and prevent the view from loading when clicked. Any suggested tips?

• Game Key Events: Event or Method Overload?

  - by Ell

  If you were going to develop a game in say, Ruby, and you were provided with a game framework, would you rather act on key up/down events by overloading a method on the main window like so: class MyGameWindow < Framework::GameWindow def button_down(id) case id when UpArrow do_something when DownArrow do_something end end end Or have an event class with which you can make a method and assign a handle to it, like so: class MyGameWindow < Framework::GameWindow def initialize key_down.add_handler(method(:do_something)) end def do_something puts "blah blah" end end Please give your views, which do you think would be better in a game developement area, and thanks in advance, ell.

• Android VideoView plays 2 videos at the same time

  - by evosoft

  I ma trying to play a videoview on top of another video view. the first video view is paused, while the second is playing. It appears to work but no second video appears on he screen (though I hear the audio and see the controls that would normally appear on top). I am assuming this is some sort of Zorder issue. Any thoughts. By the way, I have no problem displaying other views on top of the main video view and having the video fill the background.

• In ASP.NET MVC, what is the equivalent of ASP classic's server side includes?

  - by Quakkels

  I have been developing in classic ASP for about 2.5 years and I am trying to update my skill set to include ASP.NET MVC. What is the MVC way of executing SSIs? IE: How can I include a database drawn navigation list in a sidebar? I have been looking into partial views, but they seem to get their content from the controller. As far as I can tell this means that I would need to write each controller to pass the navigation list. Am I thinking along the right lines?

• MVC MapPageRoute and ActionLink

  - by Dismissile

  I have created a page route so I can integrate my MVC application with a few WebForms pages that exist in my project: public static void RegisterRoutes(RouteCollection routes) { routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); // register the report routes routes.MapPageRoute("ReportTest", "reports/test", "~/WebForms/Test.aspx" ); routes.MapRoute( "Default", // Route name "{controller}/{action}/{id}", // URL with parameters new { controller = "Home", action = "Index", id = UrlParameter.Optional } ); } This has created a problem whenever I use Html.ActionLink in my Views: <%: Html.ActionLink("Home", "Index", "Home") %> When I load the page in the browser the link appears like: http://localhost:12345/reports/test?action=Index&controller=Home Has anyone run into this before? How can I fix this?

  Hi, I want to use Open GL ES 2.0 for a new game, but I have two questions.

Q: I want to use the 4th quadrant of a Cartesian co-ordinate system for my game and not use -0.5 to +0.5 for values on screen, how once the first question is answered can I achieve this?

• How to monitor and maintain my grails application in live/production environment?

  - by fabien7474

  It is the first time I have ever launched live a website (with Grails web framework under Amazon EC2 platform and Cloud Foundry) and I realized quickly that I am not ready for monitoring and maintening correctly my application in production mode (fortunately the website is accessible to a very limited number of users) . The issues I have faced so far are: Cannot change my views. I need to redeploy my application I have no monitoring. I don't know who is connected, when do they sign in / sign out... Redploying my application (upload WAR + deploy) takes at least 30 minutes. I don't know how to restart my Tomcat server without a redeploy through Cloud Foundry ! ... So, my question is very simple: What tools (including grails plugins) and methods can you recommend me for taking me out from my current blindness?

• ASP.Net MVC elegant UI and ModelBinder authorization

  - by SDReyes

  We know authorization stuff is a cross cutting concern, and we do anything we could to avoid merge business logic in our views. But I still not found an elegant way to filter UI components (e.g. widgets, form elements, tables, etc) using the current user roles without contaminate the view with business logic. same applies for model binding. Example Form: Product Creation Fields: Name Price Discount Roles: Role Administrator Is allowed to see and modify the Name field Is allowed to see and modify the Price field Is allowed to see and modify the Discount Role Administrator assistant Is allowed to see and modify the Name Is allowed to see and modify the Price Fields shown in each role are different, and model binding needs to ignore the discount field for 'Administrator assistant' role. How would you do it?

• Simple multilingual CMS?

  - by Christoffer

  Hi, I have been searching for a while now for a dead simple CMS with multi-language support. The ideal candidate is very lean and offers the possibility to set up different languages for different domains. It's OK if the language support is provided by a plugin/extension. For example I want example.com to point to English and example.fr should be French. With different URI-mappings for SEO. It can be developed in either of PHP, Ruby or Python and has to be open source. Any tips? Thank you EDIT / MORE DETAILS What I want is a CMS that is as simple to use and grasp for a client as Radiant is, but with tabs on each resource that can translate articles to different languages. Languages have to be able to use multiple domains, one for each language. I want to easily use the same article for more than one language as well as have articles (e.g. blog posts or news stories) that are only connected to one language. The CMS should be very light in core functionality (like Radiant, unlike Drupal/Joomla) but be easily extendable with plugins.

• Prime Number - Data while loading

  - by Emroot

  Hi, I was trying in Ruby on Rails how to find a prime number. Here is my code : helper : app/helpers/test_helper.rb module TestHelper def prime_number? number index = 2 tmp = 0 while index <= number if tmp < 1 if (number % index) == 0 tmp += 1 end else return false end index += 1 end return true end end and my view : app/views/test/index.html.erb <% (2..100).each do |i| -%> <% if prime_number? i %> <%= i %> <% end -%> <% end -%> So my question is : How can you load data while it's calculating ? I mean if I replace 100 by 100000 in my view, how can I see data on my view while my helper method is calculating ? Do I need to use ajax or rails provide a tool for that ? Thank you.

• Can I use the CSS :visited pseudo class on 'wildcard' links?

  - by rabidpebble

  Let's say I have a site with multiple links as follows: www.example.com/product/1 www.example.com/product/2 www.example.com/product/3 I also append tracking info to links from time to time so that I can see how my site is being used, e.g, if somebody visits the products page from the product browser I would set a ref parameter: www.example.com/product/1&ref=pb www.example.com/product/2&ref=pb www.example.com/product/3&ref=pb The problem with this is that if the user visits a link of the first type and then views a link of the second type then the :visited pseudo class doesn't seem to apply because the browser only seems to match on exact URLs. Is there any way to have "wildcards" apply to links in this sense, so that when the user sees either the first type or the second type of link that it is highlighted? Note: I cannot change this "ref" architecture; it is inherited.

• Any MVVM frameworks work well with NavigationWindows?

  - by Will

  I'd like to "throw away" the current version of a WPF application and move version 2 to a stable MVVM framework. The main concern I'm having is that I don't see much talk about MVVM frameworks and navigation (i.e., NavigationWindows and Frames). My current app relies heavily on Pages to present views to the user. I would prefer to keep it this way. I'd rather not change everything to UserControls and rely on DataTemplates to switch out the view I need to present. Are there any MVVM frameworks that: Work well with NavigationWindows and Pages Provide ViewModels adequate access to the navigation process Provide the ability to change navigation in response to security-related events (e.g., redirect to login Page after logout)

• iPhone Live Video Stream Media Player

  - by happyhammer83

  I'm hoping to make an app that streams live video that has a view placed on top with labels and a button on it. From my research and testing of the http video streaming feature (available since iPhone 3.0 OS), it seems that you create a webview that points to the index html that contains the converted video stream, and this displays as a quicktime video in the app. This means that I don't have control over the Media Player that is opened. Does anyone know how you can control this? I know that the Apple's MoviePlayer sample code shows you how to place views on top of a MediaPlayer video, but how can this be done with a http live stream? Thanks in advance.

• Django - transactions in the model?

  - by orokusaki

  Models (disregard typos / minor syntax issues. It's just pseudo-code): class SecretModel(models.Model): some_unique_field = models.CharField(max_length=25, unique=True) # Notice this is unique. class MyModel(models.Model): secret_model = models.OneToOneField(SecretModel, editable=False) # Not in the form spam = models.CharField(max_length=15) foo = models.IntegerField() def clean(self): SecretModel.objects.create(some_unique_field=self.spam) Now if I go do this: MyModel.objects.create(spam='john', foo='OOPS') # Obviously foo won't take "OOPS" as it's an IntegerField. #.... ERROR HERE MyModel.objects.create(spam='john', foo=5) # So I try again here. #... IntegrityError because SecretModel with some_unique_field = 'john' already exists. I understand that I could put this into a view with a request transaction around it, but I want this to work in the Admin, and via an API, etc. Not just with forms, or views. How is it possible?

• Connect two UIScrollView's together

  - by johnw188

  Here's a tricky iPhone problem I've been working on. I have three UIScrollViews on a page, one that only scrolls horizontally, one that only scrolls vertically, and one that scrolls both horizontally and vertically. I want to lock the views together, so that the horizontal location of the horizontal only scrollview matches the horizontal location of the main scrollview, and the vertical scrollview likewise, so that dragging the main scrollview around controls the horizontal and vertical scrollviews. Problem is, I'm completely stumped. I've looked around inside the apple documentation, but there doesn't seem to be any way to do this officially. One thought that I had was to somehow "clone" any touch on any of the scrollviews to a point on the other two, but I have no idea how to do this. If anyone has any thoughts on this, I'd very much appreciate it.

• Appengine not liking my .jspx files

  - by Hans Westerbeek

  I have a little app that runs fine on local dev appengine, but appengine itself is not processing my .jspx files. The jspx files are in WEB-INF so they should not be excluded by appengine (as a static resource) I am using Apache Tiles to define my views. So the html produced looks like this: <html xmlns:jsp="http://java.sun.com/JSP/Page" xmlns:c="http://java.sun.com/jsp/jstl/core" xmlns:tiles="http://tiles.apache.org/tags-tiles" > <jsp:output omit-xml-declaration="yes"/> <jsp:directive.page contentType="text/html;charset=UTF-8" /> <jsp:directive.page isELIgnored="false"/> (etc etc) How can I solve this problem?
