  • How do i use findAll method with a class in Doctrine?

    - by terrani
    Hi, I am a little bit confused with Doctrine class. I created a class and its base class in Doctrine. The class's name is User. so..I created an object of class User. $oUser = new User(); when I try to use findAll method, it does not work. I found the following code on the doctrine documentation. Doctrine_Core::getTable('User')-findAll(); I don't understand why i need to call getTable to use findAll method when I have User class. Am I missing something?

  • Passing an instantiated class to concrete class derived by Castle Windsor

    - by Tr1stan
    I have a system that I'm using to test some new architecture. I have the following setup (In MVC2 .Net - C Sharp): View < Controller < Service < Repository < DB I'm using Castle Windsor as my DI (IoC) controller, and this is working just fine in both the Service and Repo layers. However, I'm now at a point where I would like to pass an Entity Framework (DatabaseNameEntity) to the constructor to the Service, and then to the Repo, so that I have something similar to a Unit of Work pattern per request (This feels like what I'm trying to achieve anyway) - and I'm having trouble working out how this can be done using Castle Windsor. Am I going off on a silly tangent? Any pointers appreciated.

  • ZipArchive php Class, would this be the best approach??

    - by SoLoGHoST
    Ok, just wondering on the versions of PHP that this class is built into. And if they are built into all platforms (OS's). I'm wanting an approach to search through a zip file and place files using file_put_contents in different filepaths within the webroot. In any case, I'm familiar with how to do this with the ZipArchive class, but I'm wondering if using this class would be a good solution and support MOST, if not ALL servers?? I mean, I'd rather not use a method that requires the Server to have it installed. I'm looking for a solution to this that will support at least MOST servers without having to install the class... Thanks :) Also, I'd like to support opening tar.gz and/or .tgz files if possible, but I don't think the ZipArchive class supports this, but perhaps a different built-in php class does??

  • Java class Class<T> and static method Class.forName() drive me crazy.

    - by matt
    Hi, this code doesn't compile. i'm wandering what i am doing wrong: private static Importable getRightInstance(String s) throws Exception { Class<Importable> c = Class.forName(s); Importable i = c.newInstance(); return i; } where Importable is an interface and the string s is the name of an implementing class. The compiler says: ./Importer.java:33: incompatible types found : java.lang.Class<capture#964 of ?> required: java.lang.Class<Importable> Class<Importable> c = Class.forName(format(s)); thanks for any help!

  • how to specify which child class this object belong to after retrieving from a hashmap?

    - by chandra wibowo
    hi everyone, i have a parent class called Course, and two child class PostgradCourse and UndergradCourse. i have a hashmap HashMap courses; i store all the postgradCourse and undergradCourse objects in the hashmap. i want to retrieve an undergradCourse object from the hashmap using the key. Course course = courses.get(courseCode); then i want to call a method in the UndergradCourse class, setUnits() method course.setUnits(); but the compiler say cannot find symbol- method setUnit() im pretty sure the problem is the compiler is looking for a method setUnit() in the Course class instead of UndergradCourse class i did this but its not working UndergradCourse course = courses.get(courseCode); results in incompatible type so how can i retrieve undergradCourse object from the hashmap as an undergradCourse object instead of course object? so then i can call a method inside the child class thanks in advance

  • Why isn't this simple test class's method inherited in Ruby?

    - by Kevin Bannister
    Consider this very simple logging class: class MockLog def self.log_stub_method(*args) args.each do |a| define_method "#{a}" do |msg| t = Time.now.strftime("%Y-%m-%d %H:%M:%S") $stderr.puts "[#{a.upcase}] \u00bb [#{t}] #{msg}" end end end log_stub_method :fatal, :error, :warn, :info, :debug end Let's add logging to all our classes: class Module def has_logging() class_eval { @log = MockLog.new def log self.class.instance_variable_get :@log end } end end Now, why doesn't this work? class Foo has_logging end Foo.new.log.nil? # => false, as expected class Bar < Foo end Bar.new.log.nil? # => true?! Why wasn't the `log` method inherited?

  • c# 3.5 class List<int> class initialisation

    - by josephj1989
    I can initialize a List like new List{1,2,3,4,5}; However List does not have a constructor which accepts a single parameter. So I tried to run this through the debugger and it seems to be calling the Add method. So how does the compiler know which method to invoke to add each individual element. This may be a silly question but I am a bit confused. Thanks

  • I want to be able to derive from a class internally, but disallow class in other assemblies to derive from the class

    - by Rokke
    Hej I have the following setup: Assembly 1 public abstract class XX<T> : XX where T: YY { } public abstract class XX {} Assembly 2 public class ZZ : YY {} public class ZZFriend : XX<ZZ> {} I use this feature in reflection when in YY: public class YY { public Type FindFriend { return GetType().Assembly.GetTypes().FirstOrDefault( t => t.BaseType != null && t.BaseType.IsGenericType && typeof(XX).IsAssignableFrom(t) && t.BaseType.GetGenericArguments().FirstOrDefault() == GetType()); } } I would like do disallow inheritance of the non generic class XX like: public class ZZFriend: XX {} Alternatively, I need a method like (that can be used in the reflection in YY.FindFrind()): public Type F(Type t) { return GetTypeThatIsGeneric(XX, Type genericTypeParameter); } That can be used in YY as: Typeof(XX<ZZ) == F(typeof(GetType()) Hope that makes sense... Thanks in advance Søren Rokkedal

  • A Reusable Builder Class for Ruby Testing

    - by Liam McLennan
    My last post was about a class for building test data objects in C#. This post describes the same tool, but implemented in Ruby. The C# version was written first but I originally came up with the solution in my head using Ruby, and then I translated it to C#. The Ruby version was easier to write and is easier to use thanks to Ruby’s dynamic nature making generics unnecessary.  Here are my example domain classes: class Person attr_accessor :name, :age def initialize(name, age) @name = name @age = age end end class Property attr_accessor :street, :manager def initialize(street, manager) @street = street @manager = manager end end and the test class showing what the builder does: class Test_Builder < Test::Unit::TestCase def setup @build = Builder.new @build.configure({ Property => lambda { Property.new '127 Creek St', @build.a(Person) }, Person => lambda { Person.new 'Liam', 26 } }) end def test_create assert_not_nil @build end def test_can_get_a_person @person = @build.a(Person) assert_not_nil @person assert_equal 'Liam', @person.name assert_equal 26, @person.age end def test_can_get_a_modified_person @person = @build.a Person do |person| person.age = 999 end assert_not_nil @person assert_equal 'Liam', @person.name assert_equal 999, @person.age end def test_can_get_a_different_type_that_depends_on_a_type_that_has_not_been_configured_yet @my_place = @build.a(Property) assert_not_nil @my_place assert_equal '127 Creek St', @my_place.street assert_equal @build.a(Person).name, @my_place.manager.name end end Finally, the implementation of Builder: class Builder # defaults is a hash of Class => creation lambda def configure defaults @defaults = defaults end def a(klass) temp = @defaults[klass].call() yield temp if block_given? temp end end

  • Strategies for invoking subclass methods on generic objects

    - by Brad Patton
    I've run into this issue in a number of places and have solved it a bunch of different ways but looking for other solutions or opinions on how to address. The scenario is when you have a collection of objects all based off of the same superclass but you want to perform certain actions based only on instances of some of the subclasses. One contrived example of this might be an HTML document made up of elements. You could have a superclass named HTMLELement and subclasses of Headings, Paragraphs, Images, Comments, etc. To invoke a common action across all of the objects you declare a virtual method in the superclass and specific implementations in all of the subclasses. So to render the document you could loop all of the different objects in the document and call a common Render() method on each instance. It's the case where again using the same generic objects in the collection I want to perform different actions for instances of specific subclass (or set of subclasses). For example (an remember this is just an example) when iterating over the collection, elements with external links need to be downloaded (e.g. JS, CSS, images) and some might require additional parsing (JS, CSS). What's the best way to handle those special cases. Some of the strategies I've used or seen used include: Virtual methods in the base class. So in the base class you have a virtual LoadExternalContent() method that does nothing and then override it in the specific subclasses that need to implement it. The benefit being that in the calling code there is no object testing you send the same message to each object and let most of them ignore it. Two downsides that I can think of. First it can make the base class very cluttered with methods that have nothing to do with most of the hierarchy. Second it assumes all of the work can be done in the called method and doesn't handle the case where there might be additional context specific actions in the calling code (i.e. you want to do something in the UI and not the model). Have methods on the class to uniquely identify the objects. This could include methods like ClassName() which return a string with the class name or other return values like enums or booleans (IsImage()). The benefit is that the calling code can use if or switch statements to filter objects to perform class specific actions. The downside is that for every new class you need to implement these methods and can look cluttered. Also performance could be less than some of the other options. Use language features to identify objects. This includes reflection and language operators to identify the objects. For example in C# there is the is operator that returns true if the instance matches the specified class. The benefit is no additional code to implement in your object hierarchy. The only downside seems to be the lack of using something like a switch statement and the fact that your calling code is a little more cluttered. Are there other strategies I am missing? Thoughts on best approaches?

  • Dynamic Type to do away with Reflection

    The dynamic type in C# 4.0 is a welcome addition to the language. One thing Ive been doing a lot with it is to remove explicit Reflection code thats often necessary when you dynamically need to walk and object hierarchy. In the past Ive had a number of ReflectionUtils that used string based expressions to walk an object hierarchy. With the introduction of dynamic much of the ReflectionUtils code can be removed for cleaner code that runs considerably faster to boot. The old Way - Reflection Heres...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

  • Enhance GIMP’s Image Editing Power with Gimp Paint Studio

    - by Asian Angel
    Does your GIMP installation need a little super-charging? Using Gimp Paint Studio you can add a wonderful set of brushes, tools, and more to GIMP and take your work up to the next level. For our example we chose to install the beta version of Gimp Paint Studio on Ubuntu 10.10. Once you download the .zip file and unzip it, all that you need to do is manually transfer the contents shown here to the appropriate GIMP folders on your system. You can see the location of the destination folders here on our system… Note: Make certain to make a back-up copy of the “sessionrc and toolrc files” before you transfer Gimp Paint Studio into your installation (in case you would like to or need to revert back to the originals later). When you finish transferring the files start GIMP up and get ready to have fun. And if your experience is like ours then you should see a noticeable difference in window size and arrangement from the default settings. Here are some samples of the exceptional artwork done by Ramon Miranda and Mozart Couto using Gimp Paint Studio. Really impressive! Artwork by Ramon Miranda & Mozart Couto. Watch the introduction video and see Gimp Paint Studio in action.

  • Box2D Static-Dynamic body joint eliminates collisions

    - by andrewz
    I have a static body A, and a dynamic body B, and a dynamic body C. A is filtered to not collide with anything, B and C collide with each other. I wish to create a joint between B and A. When I create a joint (ex. revolute), B no longer collides with C - C passes through it as if it does not exist. What am I doing wrong? How can adding a joint prevent a body from colliding with another body it used to? EDIT: I want to join B with A, and have B collide with C, but not A collide with C. In realistic terms, I'm trying to create a revolute joint between a wheel (B) and a wall (A), and have a box (C) hit the wheel and the wheel would then rotate. EDIT: I create a the simplest revolute joint I can with these parameters (C++): b2RevoluteJointDef def; def.Initialize(A, B, B -> GetWorldCenter()); world -> CreateJoint(&def);

  • Using NginX and Apache alongside for both static and dynamic files

    - by faridv
    Background: I've searched a lot and found these useful threads about using of Apache or NginX for static or dynamic files. But they are old (mostly about 1 or 2 years ago) and I think both webservers, specifically Nginx has had important changes in performance and usage. So I think take another look on these issue cannot be that bad. Nginx (for static files) and Apache (for dynamic content)? nginx better than apache for dynamic content? [closed] Apache or NGINX for PHP? Nginx as reverse proxy to Apache with only dynamic content? My question: I have a PHP web application with lots of dynamic files and lots of static contents (videos, images etc.) and it's currently running on a CentOS 6 server and Apache 2.2 since 2 months ago. In past few days, number of our site visitors have gained so fast and I just thought if this number continues to increase with current ratio, we need to change many things (web server, application, etc.) to prevent failures. Because of hardware limitations that we are facing, I thought that it's best for us to start with web server. Should I start with something else? Should I try to increase performance of my PHP application and forget about web server for now? (even if gonna take a long time!) Because of huge usage of .htaccess files (for redirection, rewrites, etc.), I think it's gonna be painful to migrate to NginX as default web server or maybe only for dynamic files. Does this mean that I can't even use Nginx as reverse proxy? I'm not sure latest stable version of NginX and PHP-FPM have a better performance over my current Apache and my limitations (too many things) won't let me to give it a try. Which one is doing better currently? What will I lose by migrating to Nginx? To make it short, what should I do?

  • How do I get the compression on specific dynamic body

    - by Mike JM
    Sorry, I could not find any tag that would suit my question. Let me first show you the image and then write what I want to do: I'm using box2D. As you can see there are three dynamic bodies connected to each other (think of it as a table from front view).The LEG1 and LEG2 are connected to the static body. (it's the ground body). Another dynamic body is falling onto the table. I need to get the compression in the LEG1 and LEG2 separately. Joints have GetReactionForce() function which returns a b2Vec, which in turn has Length() and LengthSqd functions. This will give the total sum of the forces in any taken joint. But what I need is forces in individual bodies that are connected with joints. Once you connect several bodies with a single joint it again will show the sum of forces which is not useful.Here's the case iI'm talking about:

  • How to opendns with dynamic ip

    - by Joshua Robison
    OpenDNS is almost completely useless with a dynamic ip and most people have dynamic ip addresses. There isn't even a decent client for Linux to update your IP. There is a script you can install but it only seems to update on startup and all my child needs to do is unplug and replug the cable from the wall or router and a new ip is created totally killing the opendns service . I'm not even sure the Mac or windows ip update clients can protect from such a simple maneuver . How can I get my ip address to constantly update with opendns, is my question.

  • SEO indexing with dynamic titles, keywords and description

    - by Andrea Turri
    I'm working on a worldwide website (all in one single domain) so I'm wondering to create dynamic titles, descriptions, keywords and headings for each location. What I'm doing is to get information from the IP of the user and show for example a dynamic title: var userCity = codeToGetCityFromIP; <title>Welcome to userCity</title> // and same for description, keywords and headings... Obviously the code is different... I'd like to know if it is a good solution to create multiple SEO indexing based on cities? I'm also using GeoLocation and I do same using the returned values from it. I'm doing right or there are more effective ways to indexing in different countries and cities without create multiple website for each city of the world? Thanks.
