• Are there any issues with MySQL's i18n(indic language) support ?

  - by anjanb

  Hi All, We're evaluating MySQL and PostgreSQL for building our indic language web application which will use MySQL or PostgreSQL. One of my colleagues mentioned that MySQL had issues with i18n. I mostly come from the Oracle world and although I've played a lil with MySQL, I don't know enough to know that there are issues with its i18n support. Does anyone know issues with MySQL's i18n support and if PostgreSQL would be better placed for building an application with indic language support(kannada, telugu, tamil, etc) ? Just so you know, we're going to be using J2EE to build this application and we will be using JDBC drivers to access the DB. P.S : Will anything change if we were to use Rails to build the app instead of J2EE ? Thank you,

• Best Ruby ORM for Wrapping around Legacy SQL Server Database?

  - by Technocrat

  Hi. I found this answer and it sounds like almost exactly what I'm doing. I have heard mixed answers about whether or not datamapper can support SQL Server through dataobjects. Basically, we have an app that uses a consistently structured database, consistently named tables, etc in SQL Server. We're making all kinds of tools and stuff that have to interact with it, some of them remotely and so I decided that we need to create some common, simple access point to do read/write operations on the SQL Server app since it's API is all C# and other things I despise. Now my question is if anyone has any examples or projects they know of where a ruby ORM can essentially create models for another application's legacy database by defining the conventions of each model's pkeys, fkeys, table names, etc. Sequel is the only ORM I've used with SQL Server but never to do anything quite like this. Any suggestions?

• XNA or C# Pop-up progress bar for the LoadContent() method

  - by Warlax

  Hey people, We wrote a small game using Microsoft's XNA Game Studio 3.1. The LoadContent() takes a long time because, other than loading models, and config files, we're also running some one-time (per run) terrain analysis. We are not C# or XNA programmers... we're Java programmers, and want to be able to give the user some feedback that the system is loading. Preferably, this will be through a simple pop-up with a progress bar that will say something simple like "loading please wait". The progress bar doesn't have to be a 0 to 1 progress bar, it can instead be one of those 'back and forth' progress bars. I was hoping for some quick copy-paste ready code to just do that - as it is not a central piece of our project, nor do we have a need to delve into too much documentation. I appreciate you time, effort, and possible donation. Thanks.

• Does Seaside scale?

  - by Richard Durr

  Seaside is known as "the heretical web framework". One of the points that make it heretical is that it has much shared state. That however is something which, in my current understanding, hinders easy scaling. Ruby on rails on the other hand shares as less state as possible. It has been known to scale pretty well, even if it is dog slow compared to modern smalltalk vms. flickr uses php and has scaled to an extremly big infrastructure... So has anybody some experience in the scaling of Seaside?

• Implementing Qt File Dialog with a Different File System Library (boost)

  - by knight

  Hi, I am writing an application which requires me to use another file system and file engine handlers and not the qt's default ones. Basically what I want to be able to do is to use qt's file dialog but have an underlying file system handler (for example built using boost file system library) of mine handling all the operations with regards to file and directory operations within that dialog. I have already written a custom file engine which handles some of the operations but I am now stuck with Qt's file system model and the file system watcher engine, as I need to have the signals transmitted for this custom file engine. Seems like I have a daunting task ahead. Am I heading in the right direction? Is there any other simpler way that I could implement this? Can anyone give me any idea on how to proceed. I was thinking of looking into proxy models but not sure if that would work. Thanks in advance for any help.

• What to read as a good intro and quickstart to aspect-oriented programming and metaprogramming?

  - by Ivan

  As I've found myself repeating myself a lot, writing very similar queries and classes for different entities (despite of doing strong object and relational normalisation), etc, I've came to an Idea that I could and should automate the most of this and write an engine which will compile simple declarative models I specify into all the code limiting my job to describe the task and and finally just customise the result as needed. As far as I know this is about metaprogramming and aspect-oriented programming. How do I get acquainted with modern tools available quickly so that I don't invent one more bicycle developing my own?

• Writing a custom auth system (like the default django auth system), use it to generate tables in DB

  - by dotty

  Hay all, I've been reading up on middleware and how to use it with a context object. I want to write a simple middleware class which i can use on my own applications, it will essentially be a cut down version of the django one. The problem i seem to have is that if i have INSTALLED_APPS = ('django.contrib.my_auth') in the settings file, all is well. I've also added MIDDLEWARE_CLASSES = ('django.contrib.my_auth.middleware.MyAuthMiddleware') in it and everything is fine. My question is, how would i make my middleware automatically generate tables from a models.py module, much like how the django auth does when i run manage.py syncdb? thanks

• Implementing DRY Forms

  - by virtualeyes

  Getting into Play 2.0, overall, blown away, great stuff. Anyway, wondering how one can achieve DRY forms in Play? If you look at the create & edit examples in the Computer Database Sample, you'll see that the form elements are repeated. With just 4 fields (in the sample form), no big deal, but when you're dealing with large, complex forms and/or handling many CRUD models, the duplication becomes a bigger maintenance issue. On the binding end ( form.bindFromRequest and form.fill(Foo) ), the implementation is so elegant for create/edit operations; is there a corresponding solution in the template layer?

• Inlines in Django Admin

  - by Oli

  I have two models, Order and UserProfile. Each Order has a ForeignKey to UserProfile, to associate it with that user. On the django admin page for each Order, I'd like to display the UserProfile associated with it, for easy processing of information. I have tried inlines: class UserInline(admin.TabularInline): model = UserProfile class ValuationRequestAdmin(admin.ModelAdmin): list_display = ('address1', 'address2', 'town', 'date_added') list_filter = ('town', 'date_added') ordering = ('-date_updated',) inlines = [ UserInline, ] But it complains that UserProfile "has no ForeignKey to" Order - which it doesn't, it's the other way around. Is there a way to do what I want?

• iOS Facebook SDK: FBRequestDelegate only works on AppDelegate??

  - by RMR

  Hi guys, I want to encapsulate all my Facebook interactions within a FacebookFacade class to keep things clean and tidy. I have an instance of the iOS SDK Facebook class within my FacebookFacade. My problem is that when I make a Graph API call within the facade, such as: [self.facebook requestWithGraphPath:@"me" andDelegate:self]; the only method of FBRequestDelegate that gets called is requestLoading: and nothing else. I have tried putting similar code in other places, like in controllers and other models, and there too not all of the FBRequestDelegate methods get called, only requestLoading:. In fact the only way I can get the other FBRequestDelegate methods to be called is to put all my Facebook logic in the AppDelegate and make my AppDelegate the FBRequestDelegate. Why is this the case? Am I missing something here? I definitely do not want to use the AppDelegate as my FBRequestDelegate as I don't want to confuse the purpose of the AppDelegate. Thanks.

• User settings mechanism for Yii

  - by Peterim

  Hi guys! I need some help with user settings mechanism for my Yii-based application. I've created the following db structure to store user settings: table user with the following fields id | username | email | etc. table settingslist (to store a list of all possible settings with descriptions) with the following fields id | code | name | description table settings (to store all user settings) with the following fields id | userid | settingslistcode | value Now I'm stuck with the form which allows user to change his settings. I had to deal before with the regular models (i.e. for posts, comments, etc.) where every new model had only one row in the database (Post model - id | title | body |) with the certain amount of attributes (fields of the table). But now I need to store user settings in 10-15 rows and I don't know how to apply Yii model mechanism to work with this, so I can retrieve those settings in a single form (so user could change his preferences). Any suggestions are greatly appreciated. Thank you!

• What is the best way to have a dynamic dropdownlist in PHP and POST selected value

  - by mouthpiec

  Hi, I am writing the following in PHP: i would like to have 2 dropdownlists, where the second one is populated from a mySQL dB according to the choice made on the first dropdown list. Then I would like to use the values of the selected values of the dropdownlist to call another PHP page in which I will generate a db query. Eg: List A: Car Manufactures (honda, nissan, etc) List B: Models (accord, civic, etc) Then I will have a submit button, to POST the values in another PHP file? (I have the basics of how to perform the above without having a dynamic list, but I tried this with AJAX, but I am having problems to pass the value of the second dropdownlist) Any tips of how I can perform the above?

• iOS - playing a youtube video from a webview thumbnail

  - by soleil

  Was about to finally submit an app when I realized that the youtube videos I'm playing play from the iPhone, but not the iPad. Here's the code I'm using: NSString *embedHTML = @"\ <html><head>\ <style type=\"text/css\">\ body {\ background-color: transparent;\ color: white;\ }\ </style>\ </head><body style=\"margin:0\">\ <embed id=\"yt\" src=\"%@\" type=\"application/x-shockwave-flash\" \ width=\"%0.0f\" height=\"%0.0f\"></embed>\ </body></html>"; NSString *html = [NSString stringWithFormat:embedHTML, [videoItem objectForKey:@"URL"], thumb.frame.size.width, thumb.frame.size.height]; UIWebView *videoView = [[UIWebView alloc] initWithFrame:thumb.frame]; [videoView loadHTMLString:html baseURL:nil]; [videoContainer addSubview:videoView]; Is there any reason this would work on the iPhone and not the iPad? I'm testing on a 1st generation iPad. The videos play on both iPhone models I've tested (3GS and 4S). Nothing happens at all when I tap on the webviews on the iPad.

• 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!

• OOP App Architecture: Which layer does a lazy loader sit in?

  - by JW

  I am planning the implemention an Inheritance Mapper pattern for an application component http://martinfowler.com/eaaCatalog/inheritanceMappers.html One feature it needs to have is for a domain object to reference a large list of aggreageted items (10,000 other domain objects) So I need some kind of lazy loading collection to be passed out of the aggregate root domain object to other domain objects. To keep my (php) model scripts organised i am storing them in two folders: MyComponent\ controllers\ models\ domain\ <- domain objects, DDD repository, DDD factory daccess\ <- PoEAA data mappers, SQL queries etc views\ But now I am racking my brains wondering where my lazy loading collection sits. Any suggestions / justifications for putting it in one place over another another?

• Is OpenGL required for my iPhone game?

  - by Ben X Tan

  On an iPhone: If I am writing a game that has multiple levels, with multiple animations (image sequences), jpg and png (transparent), some full screen and some not, some looped and some played once only. What is the best way of doing it? Each level might have up to 10MB of images. Add on to this music, and video (cut scenes). All 2D graphics, no 3D models. Is OpenGL required? Or can this be achieved with Quartz or Core Animation?

• How do I move Zend Framework From Development to Production?

  - by dirtylogic

  I'm just wondering if anyone else has had problems moving the Zend Framework from development to production. I changed my docroot to the public folder, updated my library path, but it's still not working out for me. The IndexController is working just fine, but my ServiceController is giving me an internal server error. ServiceController <?php class ServiceController extends Zend_Controller_Action { public function amfAction() { require_once APPLICATION_PATH . '/models/MyClass.php'; $srv = new Zend_Amf_Server(); $srv->setClass('Model_MyClass', 'MyClass'); echo $srv->handle(); exit; } }

• spring mvc nested model validation

  - by hguser

  I have two models : User,Project public class Project{ private int id; @NotEmpty(message="Project Name can not be empty") private String name; private User manager; private User operator; //getter/setter omitted } public class User{ private int id; private String name; //omit other properties and getter/setter } Now, when I create a new Project, I will submit the following parameters to ProjectController: projects?name=jhon&manager.id=1&operator.id=2... Then I will create a new Project object and insert it to db. However I have to validate the id of the manager and operator is valid,that's to say I will validate that if there is matched id in the user table. So I want to know how to implement this kind of validation?

• Error & status handling for functions

  - by Industrial

  Hi everyone, We're working with a new codeigniter based application that are cross referencing different PHP functions forwards and backwards from various libraries, models and such. We're running PHP5 on the server and we try to find a good way for managing errors and status reports that arises from the usage of our functions. While using return in functions, the execution is ended, so nothing more can be sent back. Right? What's the best practice to send a status information or error code upon ending execution of actual function? Should we look into using exceptions or any other approach? http://us.php.net/manual/en/language.exceptions.php

• Mercurial merge strategy per file type

  - by dls

  All: I want to use kdiff to merge all files with a certain suffix (say *.c, *.h) and I want to do two things (turn off premerge and use internal:other) for all files with another suffix (say *.mdl). The purpose of this is to allow me to employ a type of 'clobber merge' for a specific file type (ie: un-mergable files like configurations, auto-generated C, models, etc..) In my .hgrc I've tried: [merge-tools] kdiff3= clobbermerge=internal:other clobbermerge.premerge = False [merge-patterns] **.c = kdiff3 **.h = kdiff3 **.mdl = clobbermerge but it still triggers kdiff3 for all files. Thoughts? An extension of this would be to perform a 'clobber merge' on a directory - but once the syntax is clear for a file suffix, the dir should be easy.

• Canonicalizing XML in Ruby

  - by whazzmaster

  I'm working on a SAML gateway using Ruby/Rails and I'm attempting to write some code that validates the xml digital signature of the incoming SAML response against the x509 cert of the originating service. My problem: the signature depends on a canonicalized version of the XML that is hashed and then signed and I'm having trouble finding a ruby lib/gem that will canonicalize XML per the spec. I found a super old gem on rubyforge that is a mess but I'd be more interested if something like nokogiri supported this kind of functionality (from the nokogiri docs, it doesn't). I've googled extensively but thought I'd ask around here to see if anyone has any good insights before I go and try to write my own version or rework the existing c14n-r library.

• Running Ruby app on Apache

  - by TandemAdam

  I have been learning Ruby lately, and I want to upload a test web application to my server. But I can't figure out how to get it to run on my shared hosting. My Hosting Details Shared Hosting with JustHost (see here for list of features) OS: Linux Apache: 2.2.11 cPanel: 11.25.0-STABLE No SSH access. Can install Ruby Gems. Can't install Apache modules. Can "Manage Ruby on Rails Applications" through cPanel. Mongrel gem is installed. I built the following simple HelloWorld Ruby Rack app using Sinatra: #!/usr/bin/ruby ruby require 'rubygems' require 'sinatra' get '/hi' do "Hello World!" end I just can can't figure out how to "start" the application. Do I need to tell Mongrel (or maybe Apache) that the application exists somehow? How do I start this app running? I am happy to provide more info if needed.

• Autocomplete with Django, jQuery and google app engine

  Hey guys, I'm new to Django and jQuery, but I have a lot of python experience. I'm basically trying to write an HTML form, with one text box for now, that as you type in it, shows you auto completion options. this will be used for finding restaurants, and I intend to use the Yelp API for that. can someone please point me out in a direction of a tutorial on how to do this - specifically with regards to the Django / HTML / jQuery rather than how to work with the Yelp API? Are there any tutorials I should read? All tutorials I have found are very basic ones that build forms from the Django data models.. Thanks!
