  • Django 1.2 crash course needed

    - by delusionalweekendwarrior
    I know Python but I've never used Django. What do I need to know about Django 1.2 to port my typical PHP CRUD web application in one weekend? (Yes I've read Joel Spolsky's Netscape article :-)) I'm reading this tutorial right now and it's excellent. I'm already playing around with inspectdb to generate my models from the existing schema. I'm planning to use the following features of Django this weekend: Fragment caching Static asset versioning (for far future expires) Schema migrations (or whatever they're called in Django) Auto-admin (and customize it later) The test framework ...other stuff I probably don't know about yet I'm familiar with all these concepts in other languages/frameworks, except for the ORM which I've never used. I know SQL pretty well though. Any links, sage bits of advice, gotchas, stuff not mentioned in the (excellent) tutorial/docs, or stuff that is mentioned but warrants repeating == very welcome. Thanks!

  • Objective-C Framework PSMTabBarControl does not work

    - by ahmet2106
    Hello everybody In my App I'm trying to get PSMTabBarControl working, but all I do - nothing... I have copied the framework File in my Frameworks folder of my App, then included it. In my InterfaceBuilder (1.3.2) I was able to drag and drop the PSMTabBarControl to my Window and link it with the NSTabView (PSM - tabView - NSTabView && NSTabView - delegate - PSM), but after i tried a Demo (apple+r) I cant see the Tabs... Tried all I can - but dont know why.. Am I doing sth. wrong? Which other Framework or Source I can use to create Tabs like Firefox oder Safari? Thank you!

  • Is it worth the time to switch from AjaxControlToolkit to jQuery?

    - by Matthew Jones
    I keep hearing all these things about how awesome jQuery is and how the AjaxControlToolkit sucks. Unfortunately, I only heard about this after I built my entire WebForms site using the toolkit. Now I am considering switching, if not entirely, mostly to jQuery. This is partially for the experience (having never coded in Javascript or used any frameworks) and partially because I think I have more control over jQuery. There is no pressing need to switch, but I'm considering doing it anyway. Is it worth tackling the learning curve for jQuery just to get the experience, of should I leave my working site well enough alone?

  • Porting a PowerBuilder Application to .NET

    - by Justin Ethier
    Does anyone have any advice for migrating a PowerBuilder 10 business application to .NET? My company is considering migrating a legacy PB application to .NET (C#) and I am just wondering if anyone has any experience - good or bad - that you would like to share. The application is rather large with 10 PBL libraries, some PFC as well as custom frameworks. There are a large number of DLL calls being made as well. Finally, it uses a Microsoft SQL Server database. We have discussed porting the "core" application code to .NET and then porting more advanced functionality across as-needed.

  • JQuery removed background from iframe

    - by Webnet
    I'm trying to remove the background image on a page that's being loaded via an iframe within a lightbox effect. I have verified that body is the correct element within the iframe that's being selected, but I can't get the background image to go away. Am I missing something obvious? var body = jQuery('#fancybox-frame').contents().find('body'); body.css({ 'background': '', 'background-image': '', 'background-color': '#fff' });

  • Working with the Objective-C/Cocoa flat namespace

    - by Stephen Blinkhorn
    I've not found anything that addresses my specific name space question as yet. I am working on some AudioUnit plug-ins featuring Cocoa based GUIs. The plug-ins use a common library of user interface classes (sliders, buttons etc) which are simply added to each Xcode project. When I recompile and distribute updates it is pretty much guaranteed that at least one user interface class will have been updated since the last release. If the user launches an older plug-in before an updated plug-in then the old Cocoa classes are already loaded into the run time and the plug-in attempts to use the older implementations - often resulting in a failure one way or another. I know frameworks are the intended solution but the overhead and backwards compatibility issues are not ideal. I prefix all class names where possible but what options do I have to ensure that each plug-in contains unique class names for the shared user interface classes?

  • How can I try a new language or framework without installing it?

    - by flamingLogos
    With so many languages and frameworks that exist, and with new ones appearing all the time, I don't have the time to download, install, and configure each one to evaluate it. In the past I've run across webapps that allow one to write or paste code into a window, and see the results in realtime in the browser, usually in a tutorial setting. What are your favorite sandbox sites for a given technology? Edit: @fretj provided the link to the excellent Google Code Playground (+1 upvote), but I thought that it was just for experimenting with Google's own apps (Search, Maps, Earth, Language, etc). But it turns out that it contains a few hidden gems: In addition to their apps, you can try out the many Javascript libraries that they host including jQuery, jQuery UI, MooTools, Dojo, and Prototype Scriptaculous. They're all hidden under the Libraries category in the "Pick an API" box. I overlooked the category because I thought it was for an app called Google Libraries. There's also a Javascript category for Javascript itself.

  • Cakephp Auth Flash Messages losing style

    - by Michael
    My Auth flash messages were working earlier -- a bright green background with text in it, such as "You have successfully logged out". However, I have made quite a few changes to the site since then, and this green background has disappeared. What are the possible causes of this? (I've run my CSS through a validator -- so that doesn't seem to be the issue). Any other ideas? Thanks!

  • ORMs and Constructors

    - by Harper Shelby
    I'm looking over .NET ORM implementations, and I have a major burning question - are there any .NET ORM implemenations that don't require public properties for every field in the database? When I see examples like this, a little bell goes off in my head. I firmly believe in encapsulation, and being forced to open the kimono of my objects just to make them work nicely with persistence frameworks gives me the heebie-jeebies. Is this sort of accessibility required in all ORMs out there? If not, please point me to examples of those that don't need it!

  • Why does adding a reference to project targeting .NET Framework 4.0 fail?

    - by Malcolm Post
    We have two projects that are both class libraries. Project 1 is a VS 2008 project and targets the .NET Framework 3.5. Project 2 is a VS 2010 (release candidate) project that targets the .NET Framework 4.0. When I try to add a reference to Project 2 in Project 1, it fails with a less than informative error message. I know that if I change the target Framework for Project 2 to 3.5, then adding the reference will work. My question is, if I don't change the target frameworks, but convert Project 1 to VS 2010, will the referencing work? Stated another way, is there some inherent incompatiblity between class libraries targeting different framework versions, or is it failing for me because VS 2008 doesn't know about the 4.0 framework?

  • Most efficient way to download media files from a server from within an iPhone app.

    - by nikki
    Hi, I have an iPhone application which contains a lot of media files, so far we have been able to keep the size of the iPhone app to less than 20 MB. We add new content with new updates, it would be difficult to keep the app size within the 20 MB limit. The right thing to do here would be to fetch the files on demand from a media/web server. If you have any pointers on how to go about doing this, please suggest. What we would need is to fetch the media files (.jpg/.png images ) on demand when the user taps on a small thumbnail for the image. Are there existing frameworks/servers that provide such services to iPhone clients. Thanks.

  • In MVC framworks (such as Ruby on Rails), does usually Model spell as singular and controller and vi

    - by Jian Lin
    I usually see Ruby on Rails books using script/generate model Story name:string link:string which is a singular Story, while when it is controller script/generate controller Stories index then the Story now is Stories, which is plural. Is this a standard on Ruby on Rails? Is it true in other MVC frameworks too, like CakePHP, Symfony, Django, or TurboGears? I see that in the book Rails Space, the controller is also called User, which is the same as the model name, and it is the only exception I see. Update: also, when scaffold is done on Ruby on Rails, then automatically, the model is singular and the controller and view are both plural.

  • Is it possible to have 'sub-templates' when using MailDefinition

    - by Dan
    I am using the MailDefinition class to create html emails for my site. The only problem I am having is that there is alot of repetition in the string templates. For example the email footer along with all the associated html and css has to be repeated in each template type. Is there a way to have sub-template? or some mechanism for avoiding this repetition?

Filenames / paths are intact. If I add die() to the bottom of my layout.phtml, I get the page. Something is resetting the headers and sending a blank page. My error reporting is on and I get unrelated errors. What could this be?! Thanks!

  • Sintra app in a gem

    - by JP
    I have a Sinatra application I've created and I'd like to package it as a gem-based binary. I have my gemspec and gem set up to generate a suitable executable that points to the my_sinatra_app.rb (which is executable) but the sinatra server never runs. Any ideas why and how to make it work? my_sinatra_app executable: #!/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby # # This file was generated by RubyGems. require 'rubygems' version = ">= 0" if ARGV.first =~ /^_(.*)_$/ and Gem::Version.correct? $1 then version = $1 ARGV.shift end gem 'my_sinatra_app', version load Gem.bin_path('my_sinatra_app', 'my_sinatra_app', version)

  • Visual Studio Unit Testing of Windows Forms

    - by GWLlosa
    We're working on a project here in Visual Studio 2008. We're using the built-in testing suite provided with it (the Microsoft.VisualStudio.TestTools.UnitTesting namespace). It turns out, that much to our chagrin, a great deal of complexity (and therefore errors) have wound up coded into our UI layer. While our unit tests do a decent job of covering our business layer, our UI layer is a constant source of irritation. We'd ideally like to unit-test that, as well. Does anyone know of a good "Microsoft-compatible" way of doing that in visual studio? Will it introduce some sort of conflict to 'mix' unit testing frameworks like nUnitForms with the Microsoft stuff? Are there any obvious bear traps I should be aware of with unit-testing forms?

  • Maven and db4o dependency

    - by Jens Jansson
    I'm intrigued to test new frameworks in the Java world, and decided to create a new project that takes advantage of Maven and db4o. I'm starting to get a hang of Maven, but I have a hard time adding db4o as a dependency to the project. First problem is that db4o doesn't exist in the official Maven repositories. Next up comes the problem that db4o seem to have recently restructured their whole site's URI:s, so I'm getting 'site not found' messages all the time when I try to navigate their site. I found somewhere a potential Maven repository that should be at https://source.db4o.com/maven but I get all the time "Error reading archetype catalog https://source.db4o.com/maven Unable to locate resource in repository" when I try to access it. So, any suggestions on how I'll get db4o up through Maven? I've managing Maven through Eclipse with the M2Eclipse plugin.

  • What lessons can you learn from software maintanence?

    - by Vasil Remeniuk
    Hello everyone, In the perfect world, all the software developers would work with the cutting edge technologies, creating systems from the scratch. In the real life, almost all of us have to maintain software from time to time (unlucky ones do it on a regular basis). Personally I first 2 years of my career was fixing bugs in the company that no longer exists (it has been taken up by Oracle). And probably the biggest lesson I've learned that time - despite of the pressure, always try to get as much information about the domain as possible (even if it's irrelevant to fixing a specific bug or adding a feature) - abstract domain knowledge doesn't lose value as fast as knowledge about trendy frameworks or methodologies. What lessons have you learned from maintenance?
