• Where does the data model go in a Prism app?

  - by HawkeyeJoeS

  I'm having trouble where to put our data model in our Prism app. Most, if not all or our data will be coming from web services and the web services are unique for each module. Unfortunately, there will be objects that need to be shared (such as a person/user object). I'm really torn about whether to add these services directly to the module, so that each is truly independent, or create a separate project to house the web service proxies and business entities. The modules are being built by different teams, but will all live in the same solution (and source control, of course).

• What action is my Symfony/Doctrine generated form actually going to?

  - by Arms

  In my Symfony 1.4 project I am using the doctrine:generate-admin task to create the modules that compose my backend system. One such module is "journeys". When I view the source of the "journeys/new" page (which displays the form to create a new journey entity) the action of the form is simply "journeys" (I expected it to be "journeys/create"). The "journeys" route on its own would call the executeIndex method - however I put a log call in there and upon form submission, the log is not made. So this leads me to believe that executeIndex is NOT being called, and another piece of code is being fired upon form submission that then (depending on a hidden input in the form) calls either executeCreate() or executeUpdate(). Problem is, I don't know where that would be happening. Any insight would be much appreciated. I don't if this is relevant, but here is the routing definition for the journeys module journey: class: sfDoctrineRouteCollection options: model: journey module: journeys prefix_path: /journeys column: id with_wildcard_routes: true Thanks!

• Getting list of all existing vtables.

  - by Patrick

  In my application I have quite some void-pointers (this is because of historical reasons, application was originally written in pure C). In one of my modules I know that the void-pointers points to instances of classes that could inherit from a known base class, but I cannot be 100% sure of it. Therefore, doing a dynamic_cast on the void-pointer might give problems. Possibly, the void-pointer even points to a plain-struct (so no vptr in the struct). I would like to investigate the first 4 bytes of the memory the void-pointer is pointing to, to see if this is the address of the valid vtable. I know this is platform, maybe even compiler-version-specific, but it could help me in moving the application forward, and getting rid of all the void-pointers over a limited time period (let's say 3 years). Is there a way to get a list of all vtables in the application, or a way to check whether a pointer points to a valid vtable, and whether that instance pointing to the vtable inherits from a known base class?

• grouping objects to achieve a similar mean property for all groups

  - by cytochrome

  I have a collection of objects, each of which has a numerical 'weight'. I would like to create groups of these objects such that each group has approximately the same arithmetic mean of object weights. The groups won't necessarily have the same number of members, but the size of groups will be within one of each other. In terms of numbers, there will be between 50 and 100 objects and the maximum group size will be about 5. Is this a well-known type of problem? It seems a bit like a knapsack or partition problem. Are efficient algorithms known to solve it? As a first step, I created a python script that achieves very crude equivalence of mean weights by sorting the objects by weight, subgrouping these objects, and then distributing a member of each subgroup to one of the final groups. I am comfortable programming in python, so if existing packages or modules exist to achieve part of this functionality, I'd appreciate hearing about them. Thank you for your help and suggestions.

• Design Documents for Python/Django?

  - by british_trader

  After working on a Django project for a while, I now have to do some design documents for it (UML type stuff). However the code doesn't have classes, but instead uses views.py with modules in it... What would be the best way to show the design of my application from the initial __init__.py, to the urls.py where the HTML requests are then filtered to the specific urls.py in each of the packages and then handled by the views.py? i.e. django-app urls.py views.py settings.py manager.py __init__.py django-package urls.py views.py

• What are 3 C++ language features you expect AFTER C++0x?

  - by Vicente Botet Escriba

  If I have understood well C++0x is now on a phase to resolve pending issues, so no new features will be added. What I want to know is what new features you want to have in C++ after C++0x is released. Just to give you an idea, I have added major existing proposal that could be included after C++0x: Concepts, Contract Programming, Garbage Collection, Macro scopes, Modules, Multimethods, Reflection Answer with your favorite feature if not already in an answer and up-vote them if already present. Be free to add other features not included on this list. Please don't include here libraries. Only core language features.

• Function from other module not detecting

  - by Lethi

  I two modules in same src folder. mod1 declares function I wish to use in module mod2: -module(mod1). -export([myfunc/1]). myfunc(A) -> {ok}. In other module I not import mod1: -module(mod2). If I do "mod1:" in mod2 it recognizes "myfunc", problem is at run-time when I call mod1:myfunc(A) I get "undefined function mod1:myfunc/1" I not understand why I get error if intellisense detect my mod1 function in mod2?

• Silverlight PRISM and 'loose' style files

  - by Suiva

  Hi, We are looking at starting a new Silverlight project using the PRISM framework (to benefit from modules etc) and I am still a little unclear about the best styling approach. What I'd ideally like is to have editable XAML files (maybe even just 1 for the whole project) containing the application's style so that they can be edited to change the look and feel of the application without having to recompile everything. Is this approach something people use? I guess it would need to load the file in at startup and apply the style which I assume wouldn't be a massive overhead. Just wondering what approaches people use Thanks for your time

• File/module structure in Python

  - by keithjgrant

  So I'm just getting started with Python, and currently working my way through diveintopython.org. The code examples are nice, but the vast majority of them are little four-line snippets, and I want to see a little more of the big picture. As I understand it--and correct me if I'm wrong--each '.py' file becomes a "module", and a group of modules in a directory becomes a "package" (at least, it does if I create a __init__.py file in that directory). What is it if I don't have a __init__.py file? So what does each "module" file look like? Do I generally define only one class in the file? Does anything else go in that file besides the class definition and maybe a handful of import commands?

• Working with version control on a Drupal/CMS project

  - by Jens Ljungblad

  I was wondering how teams that develop sites using Drupal (or any other CMS) integrate version control, subversion, git or similar, into their workflow. You'd obviously want your custom code and theme files under version control but when you use a CMS such as Drupal a lot of the work consists of configuring modules and settings all of which is stored in the database. So when you are a team of developers, how do you collaborate on a project like this? Dumping the database into a file and putting that file under version control might work I guess, but when the site is live the client is constantly adding content which makes syncing a bit problematic. I'd love to know how others are doing this.

• How reduce dll size again

  - by cemick

  My dll have been bigger multiplied up many times than early for some reason. I begining to size up the situation: A source hasn't changed. Debug information everywhere turned off. Dll use package "Pack", but not include in Runtime Packages options. I've compared new dll with old version dll thought the instrumentality of PE Explore. In new dll I find out many modules with prefix 'ec' implicitly imported unlike old dll. Package "Pack" using ecControls components Dll doesn't using explicitly call to ecControls units. Why ecControls units imported in dll? Have anybody some advice?

• (Symfony) How can i change the templating of a form in sfDoctrineGuardPlugin ?

  - by ruic

  How can i change the templating of a form in sfDoctrineGuardPlugin? That is, I need to change the html (class, id) of the input elements (username, password) of a login form provided by sfDoctrineGuardPlugin. I've changed apps/app_name/modules/sfGuardAuth/templates/singinSuccess.php, but it then just echoes $form (I need to change contents of that part - $form): <form action="<?php echo url_for('@sf_guard_signin') ?>" method="post"> <table> <?php echo $form ?> </table> <input type="submit" class="go_button" value="ir" /> <a href="<?php echo url_for('@sf_guard_password') ?>"><?php echo __('Forgot your password?') ?></a> </form> (It really should be something like changing a _form.php = I cant find this, though :S) Thank you all for any answers provided =)

• Static assembly initialization

  - by ph0enix

  I'm attempting to develop an Interceptor framework (in C#) where I can simply implement some interfaces, and through the use of some static initialization, register all my Interceptors with a common Dispatcher to be invoked at a later time. The problem lies in the fact that my Interceptor implementations are never actually referenced by my application so the static constructors never get called, and as a result, the Interceptors are never registered. If possible, I would like to keep all references to my Interceptor libraries out of my application, as this is my way of (hopefully) enforcing loose coupling across different modules. Hopefully this makes some sense. Let me know if there's anything I can clarify... Does anyone have any ideas, or perhaps a better way to go about implementing my Interceptor pattern? TIA, Jeremy

• Magento module - database not initialized?

  - by Magnus

  Hello, So I've installed an extension in my Magento Enterprise. I've been able to configure new options in the admin interface after installing the module. However in the frontend it complains "table not found". Checking the database that is indeed true. Seems the mysql4-*.php scripts have not been run or failed. Is there a log or something I can look at to see what goes wrong? From what I've read (difficult to find documentation on this) the modules db should've been initialized on the first request after it was installed and activated. Any other suggestions to what I can check to find out why it's not initialized properly?

• Can you make an Extension Method Static/Shared?

  - by Matt Thrower

  OK, I've probably misunderstood something here but, as far as I can see ... An extension method has to be contained in a module, not a class You can't make methods in modules Static/Shared Therefore you can't use an extension method on a class without instantiating it. In other words you can't make an extension method on String called "MyExtensionMethod" and use: String.MyExtensionMethod("String") But instead .. Dim test As String test.MyExtensionMethod("string") Is this correct? Or is there a way I can get extension methods to work as static methods?

• Using PHP's $_COOKIE to create cookie.txt for cURL

  - by boogie

  Hi, I'm running Drupal and Mediawiki on my server under the same domain. They are connected to each other with extensions/modules. Meaning if I log in to Mediawiki, it automatically logs into Drupal also. Mediawiki has some extensions that filter the information shown on the page. What I want to do is to show that filtered information from Mediawiki on my Drupal page. I'm trying to fetch the data with PHP cURL, but I'm not able to force it to use the login information. How can I convert PHP's $_COOKIE into cURL cookie.txt format? I suppose after that I'm able to fetch the data from Mediawiki with the right permissions. This is what print_r($_COOKIE) outputs: [wiki_session] = gg05lhd6pcfs5g6iokhoo0gue7 [wikiUserName] = WikiSysop [wikiLoggedOut] = 20100510110913 [wikiUserID] = 1 [wikiToken] = 52cdb19a7b4a43e5a2f86939e4f54941 Thanks for any help!

• Is it good practice to export variables in Perl?

  - by gvkv

  I'm finding it very convenient to pass configuration and other data that is read or calculated once but then used many times throughout a program by using Perl's use mechanism. I'm doing this by exporting a hash into the caller's namespace. For example: package Myconfiguration; my %config; sub import { my $callpkg = caller(0); my $expsym = $_[1]; configure() unless %config; *{"$callpkg\::$expsym"} = \%config; } and then in other modules: use MyConfiguration (loc_config_sym); if ( $loc_config_sym{paramater} ) { # ... do stuff ... } However, I'm not sure about this as a best practice. Is it better to add a method that returns a hash ref with the data? Something else?

• Is it possible to place Joomla under revision control?

  - by Tom

  We are a team of many developers working on a website that uses both Joomla and custom PHP scripts. The problem is that there are multiple developers working on various features which need to update information in Joomla (adding modules, changing existing ones or changing settings) and when one developer changes something, he usually makes the change locally first and then does the same thing (hopefully) on the production server. Not only that this is very error-prone, but the developers often forget to tell other developers about the changes. The custom PHP scripts are easily shared between developers, but the changes in Joomla are often forgotten and they lead to serious conflicts when a developer tries to replicate his local changes in production. I have thought about placing Joomla in a Mercurial repository, but how could we distribute the changes in the database between the development, the testing and the production machines?

• Rails 2.3.5: How does one access code inside of lib/directory/file.rb?

  - by randombits

  I created a file so I can share a method amongst many models in lib/foo/bar_woo.rb. Inside of bar_woo.rb I defined the following: module BarWoo def hello puts "hello" end end Then in my model I'm doing something like: def MyModel < ActiveRecord::Base include Foo::BarWoo def some_method Foo::BarWoo.hello end end The interpreter is complaining that it expected bar_woo.rb to define Foo::BarWoo. The Agile Web Development with Rails book states that if files contain classes or modules and the files are named using the lowercase form of the class or module name, then Rails will load the file automatically. I didn't require it because of this.

• How to write a build script for a C++ project

  - by Paul

  I am developing a C++ application on Ubuntu. The application consists of several modules, each with its makefile. I want to have a customised command line build process that does the following: checks code out from a repository (for specified branch/tag) builds the app (release or debug as specified) logs any errors etc I am too lazy to learn Perl (I tried before, but cant seem to get my head around it). Are there any (preferably open source) tools anyone can suggest, or maybe a simpler scripting languuage - or do I really have to learn Perl?

• how to create english language dictionary application with python (django)?

  - by sintaloo

  Hi All, I would like to create an online dictionary application by using python (or with django). It will be similar to http://dictionary.reference.com/. My question is (1) Are there any existing open source python package or modules or application which implements this functionality that I can use or study from? (2) If the answer to the first question is NO. which algorithm should I follow to create such web application? Can I simply use the python built-in dictionary object for this job? so that the dictionary object's key will be the english word and the value will be the explanation. is this OK in term of performance? OR Do I have to create my own Tree Object to speed up the search? or any existing package which handles this job properly? Thank you very much.
