  • RoR - Associations into practise - forms (View)

    - by NicoJuicy
    I'm learning Ruby on Rails. I'm using some associations (has_many :through, ...) But i'm having some problems with it when i'm combining my views. How exactly do i combine these nested forms? Can i do this with partial forms and where do i have to write extra code for this? I have seen examples only use the "view" and others also edit the controller.... An example would be very nice :-)

  • MVC3 - render view that is not a method in a controller

    - by scoo-b
    I don't know how to best describe my requirement, but here goes. I'm trying to render a view from the following controller/model in a nopCommerce application: CustomerController.cs snippet: [NonAction] protected CustomerNavigationModel GetCustomerNavigationModel(Customer customer) { var model = new CustomerNavigationModel(); model.HideAvatar = !_customerSettings.AllowCustomersToUploadAvatars; model.HideRewardPoints = !_rewardPointsSettings.Enabled; model.HideForumSubscriptions = !_forumSettings.ForumsEnabled || !_forumSettings.AllowCustomersToManageSubscriptions; model.HideReturnRequests = !_orderSettings.ReturnRequestsEnabled || _orderService.SearchReturnRequests(customer.Id, 0, null).Count == 0; model.HideDownloadableProducts = _customerSettings.HideDownloadableProductsTab; model.HideBackInStockSubscriptions = _customerSettings.HideBackInStockSubscriptionsTab; return model; } CustomerNavigationModel.cs: public partial class CustomerNavigationModel : BaseNopModel { public bool HideInfo { get; set; } public bool HideAddresses { get; set; } public bool HideOrders { get; set; } public bool HideBackInStockSubscriptions { get; set; } public bool HideReturnRequests { get; set; } public bool HideDownloadableProducts { get; set; } public bool HideRewardPoints { get; set; } public bool HideChangePassword { get; set; } public bool HideAvatar { get; set; } public bool HideForumSubscriptions { get; set; } public CustomerNavigationEnum SelectedTab { get; set; } } public enum CustomerNavigationEnum { Info, Addresses, Orders, BackInStockSubscriptions, ReturnRequests, DownloadableProducts, RewardPoints, ChangePassword, Avatar, ForumSubscriptions } MyAccountNavigation.cshtml snippet: @model CustomerNavigationModel @using Nop.Web.Models.Customer; @if (!Model.HideInfo) { <li><a href="@Url.RouteUrl("CustomerInfo")" class="@if (Model.SelectedTab == CustomerNavigationEnum.Info) {<text>active</text>} else {<text>inactive</text>}">@T("Account.CustomerInfo")</a></li>} Views: @Html.Partial("MyAccountNavigation", Model.NavigationModel, new ViewDataDictionary()) I am aware that it is unable to render MyAccountNavigation because it doesn't exist in the controller. However, depending on which page the syntax is placed it works. So is there a way to achieve that without changing the code in the controller? Thanks in advance.

  • Eclipse on Ubuntu: Rectangles instead of Strings and some Java methods and classes

    - by Claus Hausberger
    after upgrading from Ubuntu 9.04. to 11.04 (new installation), I have weird problems with the Eclipse editor. With the Eclipse PyDev plugin, whenever I typ single quoted strings like 'bla', they appear as rectangles (both the quotes as well as the string). First I thought this was a problem with the PyDev plugin, but it also happens with Java and Scala Plugins. With Java, it happens, for example, when typing System.out.println("bla") and then "out" is shown as rectangles only. Weird is that for about half a second I see "System.out.println" and then the editor changes it to System.[][][].println (not really [] (here I used two brackets), it is shown as rectangles). This is very weird. I've never had this before with any Ubuntu, Java or Eclipse version. Currently, I use: Ubuntu 11.04. Eclipse 3.6 Java 1.6.0_25 The latest plugins for Python (2.1) and Scala (beta 5) where used. Eclipse and Ubuntu Terminal is set to UTF-8. The problem also happens when using KDE instead of Gnome. I doubt is has anything to do with Java as I use the same versions on older Ubuntu installations (10.04, 9.10, etc) at work. It does not happen with Netbeans. But I saw once error dialog message from the Update Manager where there were some rectangles in the error widget. Maybe this is the same problem Any ideas what could be wrong here and how to fix this? Eclipse is unusable but I need this for work and also for Scala and Python (the Eclipse plugins for those are very good now). Claus

  • Hiera + Puppet classes

    - by Amadan
    I'm trying to figure out Puppet (3.0) and how it relates to built-in Hiera. So this is what I tried, an extremely simple example (I'll make a more complex hierarchy when I manage to get the simple one working): # /etc/puppet/hiera.yaml :backends: - yaml :hierarchy: - common :yaml: :datadir: /etc/puppet/hieradata # /etc/puppet/hieradata/common.yaml test::param: value # /etc/puppet/modules/test/manifests/init.pp class test ($param) { notice($param) } # /etc/puppet/manifests/site.pp include test If I directly apply it, it's fine: $ puppet apply /etc/puppet/manifests/site.pp Scope(Class[Test]): value If I go through puppet master, it's not fine: $ puppet agent --test Could not retrieve catalog from remote server: Error 400 on SERVER: Must pass param to Class[Test] at /etc/puppet/manifests/site.pp:1 on node <nodename> What am I missing? EDIT: I just left the office but a thought struck me: I should probably restart puppet master so it can see the new hiera.conf. I'll try that on Monday; in the meantime, if anyone figures out some not-it problem, I'd appreciate it :)

  • Is there an way to get the top level classes included in a puppet node?

    - by pwan
    Is there an easy way to return the top level classes applied to a node. By this I mean the classes included in a node definition or ENC equivalent For example with the sample node below, I'd like to return 'return::me' and 'return::me2' for somehost, but not 'dontreturn::me' class return::me { include dontreturn::me } node "somehost" { include return::me include return::me2 } I see that /var/lib/puppet/state/classes.txt includes the full list of classes applied to the node, but that includes any additional classes included by to the top level classes. Is there some way to get at this data with a puppet faces command ? I suspect 'puppet nodes' might be useful, but I haven't been able to get it return what I what.

  • Puppet inheritance of parametrized classes

    - by paweloque
    I have a situation in puppet where I want to inherit from a parametrized class: class base ($basepath) { ... } class extends_base ($ext_param) inherits base { ... } Now trying to instantiate the extends_base class I get the following error message: Must pass basepath to Class[Base] However, I don't see a way how to pass the basepath parameter to the Base class.. I tried to pass the param in the Class[Extends_base] definition, puppet doesn't like this either.

  • Generating Java classes out of XMLSchema.xsd using JAXB

    - by Christian Schulz
    I'm using jaxb to generate java classes out of a xml schema. The schema imports XMLSchema.xsd and its content is used as an element in the document. If I remove the import and the reference to "xsd:schema" respectively then the binding compiler generates successfully the classes. If I do not then it would produce the following errors, which are the same if I would try to generate Java classes from the XMLSchema.xsd only!

  • Contructor parameters for dependent classes with Unity Framework

    - by Onisemus
    I just started using the Unity Application Block to try to decouple my classes and make it easier for unit testing. I ran into a problem though that I'm not sure how to get around. Looked through the documentation and did some Googling but I'm coming up dry. Here's the situation: I have a facade-type class which is a chat bot. It is a singleton class which handles all sort of secondary classes and provides a central place to launch and configure the bot. I also have a class called AccessManager which, well, manages access to bot commands and resources. Boiled down to the essence, I have the classes set up like so. public class Bot { public string Owner { get; private set; } public string WorkingDirectory { get; private set; } private IAccessManager AccessManager; private Bot() { // do some setup // LoadConfig sets the Owner & WorkingDirectory variables LoadConfig(); // init the access mmanager AccessManager = new MyAccessManager(this); } public static Bot Instance() { // singleton code } ... } And the AccessManager class: public class MyAccessManager : IAccessManager { private Bot botReference; public MyAccesManager(Bot botReference) { this.botReference = botReference; SetOwnerAccess(botReference.Owner); } private void LoadConfig() { string configPath = Path.Combine( botReference.WorkingDirectory, "access.config"); // do stuff to read from config file } ... } I would like to change this design to use the Unity Application Block. I'd like to use Unity to generate the Bot singleton and to load the AccessManager interface in some sort of bootstrapping method that runs before anything else does. public static void BootStrapSystem() { IUnityContainer container = new UnityContainer(); // create new bot instance Bot newBot = Bot.Instance(); // register bot instance container.RegisterInstance<Bot>(newBot); // register access manager container.RegisterType<IAccessManager,MyAccessManager>(newBot); } And when I want to get a reference to the Access Manager inside the Bot constructor I can just do: IAcessManager accessManager = container.Resolve<IAccessManager>(); And elsewhere in the system to get a reference to the Bot singleton: // do this Bot botInstance = container.Resolve<Bot>(); // instead of this Bot botInstance = Bot.Instance(); The problem is the method BootStrapSystem() is going to blow up. When I create a bot instance it's going to try to resolve IAccessManager but won't be able to because I haven't registered the types yet (that's the next line). But I can't move the registration in front of the Bot creation because as part of the registration I need to pass the Bot as a parameter! Circular dependencies!! Gah!!! This indicates to me I have a flaw in the way I have this structured. But how do I fix it? Help!!

  • Building Dynamic Classes in Objective C

    - by kjell_
    I'm a somewhat competent ruby programmer. Yesterday I decided to finally try my hand with Apple's Cocoa frameworks. Help me see things the ObjC way? I'm trying to get my head around objc_allocateClassPair and objc_registerClassPair. My goal is to dynamically generate a few classes and then be able to use them as I would any other class. Does this work in Obj C? Having allocated and registered class A, I get a compile error when calling [[A alloc] init]; (it says 'A' Undeclared). I can only instantiate A using runtime's objc_getClass method. Is there any way to tell the compiler about A and pass it messages like I would NSString? A compiler flag or something? I have 10 or so other classes (B, C, …), all with the same superclass. I want to message them directly in code ([A classMethod], [B classMethod], …) without needing objc_getClass. Am I trying to be too dynamic here or just botching my implementation? It looks something like this… NSString *name = @"test"; Class newClass = objc_allocateClassPair([NSString class], [name UTF8String], 0); objc_registerClassPair(newClass); id a = [[objc_getClass("A") alloc] init]; NSLog(@"new class: %@ superclass: %@", a, [a superclass]); //[[A alloc] init]; blows up.

  • wxOSX/Carbon: wxGLCanvas mouse offset in non-floating window classes

    - by srose
    Hi All, I mainly program plugins using wxWidgets within a Carbon bundle which is loaded at runtime. The host-applications where my plugins are running in provide a native window handle (WindowRef), which I can use to add my custom, wxWidgets-based GUI-classes. To use the native window handle with wxWidgets classes I had to write a wxTopLevelWindow wrapper class, which does all the WindowRef encapsulation. So far, this works pretty well, but under some circumstances I got vertical mouse offsets within a wxGLCanvas if the window class of the native window handle is not of the type "kFloatingWindowClass". I am able to bypass the problem if I display an info panel (wxPanel) over the whole wxGlCanvas and if the user hides the info panel then the mouse offset is gone. Now my questions: Is there a "simple" explanation for this behaviour? Is it possible to use certain method calls to imitate info panel effect without using the panel itself? I tried several combinations of Update() and Refresh() calls of all involved components, but none of them worked so far. Even the use of wxSizer couldn't help here. Window hierarchy used by plugin-applications: wxCustomTopLevelWindow (WindowRef provided by host-application) wxPanel (parent window for all application panel) wxPanel (application info panel) wxPanel (application main panel) wxPanel (opengl main panel) wxGlCanvas (main opengl canvas) Any ideas? Any help is very appreciated.

  • Two classes and inline functions

    - by klew
    I have two classes and both of them uses some of the other class, on example: // class1.h class Class1; #include "class2.h" class Class1 { public: static Class2 *C2; ... }; // class2.h class Class2; #include "class1.h" class Class2 { public: static Class1 *C1; ... }; And when I define it like in example above, it works (I also have some #ifndef to avoid infinite header recurency). But I also want to add some inline functions to my classes. And I read here that I should put definition of inline function in header file, because it won't work if I'll put them in cpp file and want to call them from other cpp file (when I do it I get undefined reference during linking). But the problem here is with something like this: // class1.h ... inline void Class1::Foo() { C2->Bar(); } I get error: invalid use of incomplete type ‘struct Class2’. So how can I do it?

  • Restricting dynamically loaded classes and jars based on a security policy

    - by Max
    Hi, I would like to dynamically load a set of jars or classes (i.e. plugins loaded at runtime). At the same time, I would like to restrict what these plugins are able to do in the JVM. For a test case, I would like to restrict them to pretty much everything (right now I'm just allowing one System.getProperty value to be read). I am currently using a security policy file, but I'm having difficulty specifying a policy for one folder or package in my codeBase, but not another. Here is how my policy looks now: grant codeBase "file:/home/max/programming/java/plugin/plugins/" { permission java.util.PropertyPermission "java.version", "read"; }; grant codeBase "file:/home/max/programming/java/plugin/api/" { permission java.security.AllPermission; }; Where (for testing purposes), all files in the plugins package and folder are restricted, but the classes in the api folder are not. Is this possible? Do I have to create a custom class loader? Is there a better way to go about doing this? Thanks.

  • How do attribute classes work?

    - by AaronLS
    My searches keep turning up only guides explaining how to use and apply attributes to a class. I want to learn how to create my own attribute classes and the mechanics of how they work. How are attribute classes instantiated? Are they instantiated when the class they are applied to is instantiated? Is one instantiated for each class instantiated that it is applied to? E.g. if I apply the SerializableAttribute class to a MyData class, and I instantiate 5 MyData instances, will there be 5 instances of the SerializbleAttribute class created behind the scenes? Or is there just one instance shared between all of them? How do attribute class instances access the class they are associated with? How does a SerializableAttribute class access the class it is applied to so that it can serialize it's data? Does it have some sort of SerializableAttribute.ThisIsTheInstanceIAmAppliedTo property? :) Or does it work in the reverse direction that whenever I serialize something, the Serialize function I pass the MyClass instance to will reflectively go through the Attributes and find the SerialiableAttribute instance?

  • Javascript hide/show classes with checkbox

    - by Christina
    I am just learning javascript, so please bear with me! I want to be able to use checkboxes to choose to hide/show div classes (to basically filter the amount of info being shown). It is done in this... but I'm try to figure out something much simpler (since I don't need to dynamically generate the checkbox options.) I came across this example: The Javascript: function showMe (it, box) { var vis = (box.checked) ? "block" : "none"; document.getElementById(it).style.display = vis; } The HTML <form> <input type="checkbox" checked="checked" value="value1" onclick="showMe('div1', this)" />value1 <input type="checkbox" checked="checked" value="value2" onclick="showMe('div2', this)" />value2 <input type="checkbox" checked="checked" value="value3" onclick="showMe('div3', this)" />value3 </form> <div id="div1" style="display:block">Show Div 1</div> <div id="div2" style="display:block">Show Div 2</div> <div id="div3" style="display:block">Show Div 3</div> </body> </html> But it only works for div ids, not classes. Any idea on how I can work this? Thanks in advance if you can help me out!

  • Storing an object to use in multiple classes

    - by Aaron Sanders
    I am wondering the best way to store an object in memory that is used in a lot of classes throughout an application. Let me set up my problem for you: We have multiple databases, 1 per customer. We also have a master table and each row is detailed information about the databases such as database name, server IP it's located and a few config settings. I have an application that loops through those multiple databases and runs some updates on them. The settings I mentioned above are updated each loop iteration into memory. The application then runs through series of processes that include multiple classes using this data. The data never changes during the processes, only during the loop iteration. The variables are related to a customer, so I have them stored in a customer class. I suppose I could make all of the members shared or should I use a singleton for the customer class? I've never actually used a singleton, only read they are good in this type of situation. Are there better solutions to this type of scenario? Also, I could have plans for this application to be multithreaded later. Sorry if this is confusing. If you have questions, let me know and I will answer them. Thanks for your help.

  • jQuery element with multiple classes: storing one class as a var

    - by Aaron
    I'm trying to create a standardized show/hide element system, like so: <div class="opener popup_1">Click Me</div> <div class="popup popup_1">I'm usually hidden</div> Clicking on the div with the opener class should show() the div with the popup class. I don't know how many opener/popup combinations I'm going to have on any given page, I don't know where on any given page the opener and the popup are going to be displayed, and I don't know how many popups a given opener should call show() for. Both the opener and the popup have to be able to have more classes than just what's used by jQuery. What I'd like to do is something like this: $(".opener").click(function() { var openerTarget = $(this).attr("class").filter(function() { return this.class.match(/^popup_([a-zA-Z0-9-_\+]*) ?$/); }); $(".popup." + openerTarget).show(); The idea is that when you click on an opener, it filters out "popup_whatever" from opener's classes and stores that as openerTarget. Then anything with class=popup and openerTarget will be shown.

  • Object Oriented Programming in AS3

    - by Jordan
    I'm building a game in as3 that has balls moving and bouncing off the walls. When the user clicks an explosion appears and any ball that hits that explosion explodes too. Any ball that then hits that explosion explodes and so on. My question is what would be the best class structure for the balls. I have a level system to control levels and such and I've already come up with working ways to code the balls. Here's what I've done. My first attempt was to create a class for Movement, Bounce, Explosion and finally Orb. These all extended each other in the order I just named them. I got it working but having Bounce extend Movement and Explosion extend Bounce, it just doesn't seem very object oriented because what if I wanted to add a box class that didn't move, but did explode? I would need a separate class for that explosion. My second attempt was to create Movement, Bounce and Explosion without extending anything. Instead I passed in a reference to the Orb class to each. Then the class stores that reference and does what it needs to do based on events that are dispatched by the Orb such as update, which was broadcast from Orb every enter frame. This would drive the movement and bounce and also the explosion when the time came. This attempt worked as well but it just doesn't seem right. I've also thought about using Interfaces but because they are more of an outline for classes, I feel like code reuse goes out the window as each class would need its own code for a specific task even if that task is exactly the same. I feel as if I'm searching for some form of multiple inheritance for classes that as3 does not support. Can someone explain to me a better way of doing what I'm attempting to do? Am I being to "Object Oriented" by having classed for Movement, Bounce, Explosion and Orb? Are Interfaces the way to go? Any feedback is appreciated!

  • why is OOP hard for me?

    - by netrox
    I have trouble writing OOP in PHP... I understand the concept but I never create classes for my projects... mainly because it's often a small project and nothing complex. But when I read OOP, it seems more difficult to code than writing simple procedural statements. It also seems to take a lot of room as well with so many empty abstract classes and that can be easily lost in the land of objects... it's becoming like a junkyard to me. Also, I noticed that virtually all instructions on how to use OOP use "car" or "cat" or "dog" analogies. Hello... we're not dealing with animals or cars... we're dealing with windows or consoles. You can talk about analogies to death and I will never learn. What I want is see a code that's written to show how objects are created - not, "aCow-moo!" For example, I want to see a browser window object displaying say... three inputs. I want to see an "object" created to output a window with three inputs then I want to see how overriding works, like change the window object to display only two inputs instead of three inputs. I think that would make learning more easy, wouldn't it? Any recommended tutorials of that nature instead of quacks, moos, and woofs.

  • Unit test project doesn't recognize the classes it was generated from

    - by DougLeary
    I have a fairly simple file-system website consisting of one aspx page and several classes in separate .cs files. Everything is on my own HD. The web app itself builds and runs fine. Out of curiosity I decided to try out Visual Studio's nifty, easy-to-use unit test feature. So I opened each class file and clicked Create Unit Tests. VS generated a test project containing a set of test classes and some other files. Easy! But when I try to build or run the test project it throws a series of build errors, one for every class: The type or namespace name 'class-name' could not be found (are you missing a using directive or an assembly reference?). Somebody asked if my test project has a reference to the original project. Well no, because the original project is a file-system website. It has no bin folder and no DLL, so there's nothing to reference as far as I can tell. I would think that since VS generated these unit tests it would generate whatever references it needs, but apparently not. Is generating unit tests for file-system web apps an undocumented no-no, or is there a magic trick to getting it to work?

  • c# multi inheritance

    - by user326839
    So ive got a base class which requires a Socket: class Sock { public Socket s; public Sock(Socket s) { this.s = s; } public virtual void Process(byte[] data) { } ... } then ive got another class. if a new socket gets accepted a new instance of this class will be created: class Game : Sock { public Random Random = new Random(); public Timerr Timers; public Test Test; public Game(Socket s) : base(s) { } public static void ReceiveNewSocket(object s) { Game Client = new Game((Socket)s); Client.Start(); } public override void Process(byte[] buf) { Timers = new Timerr(s); Test = new Test(s); Test.T(); } } in the Sock class ive got a virtual function that gets overwritten by the Game class.(Process function) in this function im calling a function from the Test Class(Test+ Timerr Class: class Test : Game { public Test(Socket s) : base(s) { } public void T() { Console.WriteLine(Random.Next(0, 10)); Timers.Start(); } } class Timerr : Game { public Timerr(Socket s) : base(s) { } public void Start() { Console.WriteLine("test"); } } ) So in the Process function im calling a function in Test. And in this function(T) i need to call a function from the Timerr Class.But the problem is its always NULL , although the constructor is called in Process. And e.g. the Random Class can be called, i guess its because its defined with the constructor.: public Random Random = new Random(); and thats why the other classes(without a constructor): public Timerr Timers; public Test Test; are always null in the inherited class Test.But its essentiel that i call other Methods of other classes in this function.How could i solve that?

  • Toggle two divs and classes

    - by kuswantin
    I have two links with classes (login-form and register-form) relevant to their target forms ID, they want to toggle. I have also a predefined 'slideToggle' function to toggle better. This is what I have tried so far: $('#userbar a').click(function() { var c = $(this).attr('class'); $('#userbar a').removeClass('active'); $(this).toggleClass('active'); $('#register-form,#login-form').hide(); //bad, causing flashy $('#' + c).slideToggle('slow'); return false; }); With this I have trouble with the flashy window, and to correctly toggle the active classes when another link is clicked, the other link should not have active class anymore. Additional problem is the link is dead on serial clicks. I have another try, longer one: $('#userbar a').click(function() { var c = $(this).attr('class'); switch (c) { case 'login-form': $('#' + c).slideToggle('slow'); $(this).toggleClass('active'); $('#register-form').hide(); break; case 'register-form': $('#' + c).slideToggle('slow'); $(this).toggleClass('active'); $('#login-form').hide(); break; } return false; }); This one is worse than the first :( Any suggestion to correct the behavior? What I want is when a link with class login-form is click, so toggle the form with ID login-form, and hide the register-form if open. Any help would be very much appreciated. Thanks.

  • DRYing out implementation of ICloneable in several classes

    - by Sarah Vessels
    I have several different classes that I want to be cloneable: GenericRow, GenericRows, ParticularRow, and ParticularRows. There is the following class hierarchy: GenericRow is the parent of ParticularRow, and GenericRows is the parent of ParticularRows. Each class implements ICloneable because I want to be able to create deep copies of instances of each. I find myself writing the exact same code for Clone() in each class: object ICloneable.Clone() { object clone; using (var stream = new MemoryStream()) { var formatter = new BinaryFormatter(); // Serialize this object formatter.Serialize(stream, this); stream.Position = 0; // Deserialize to another object clone = formatter.Deserialize(stream); } return clone; } I then provide a convenience wrapper method, for example in GenericRows: public GenericRows Clone() { return (GenericRows)((ICloneable)this).Clone(); } I am fine with the convenience wrapper methods looking about the same in each class because it's very little code and it does differ from class to class by return type, cast, etc. However, ICloneable.Clone() is identical in all four classes. Can I abstract this somehow so it is only defined in one place? My concern was that if I made some utility class/object extension method, it would not correctly make a deep copy of the particular instance I want copied. Is this a good idea anyway?

  • Multiple Inheritence with same Base Classes in Python

    - by Jordan Reiter
    I'm trying to wrap my head around multiple inheritance in python. Suppose I have the following base class: class Structure(object): def build(self, *args): print "I am building a structure!" self.components = args And let's say I have two classes that inherit from it: class House(Structure): def build(self, *args): print "I am building a house!" super(House, self).build(*args) class School(Structure): def build(self, type="Elementary", *args): print "I am building a school!" super(School, self).build(*args) Finally, a create a class that uses multiple inheritance: class SchoolHouse(School, House): def build(self, *args): print "I am building a schoolhouse!" super(School, self).build(*args) Then, I create a SchoolHouse object and run build on it: >>> sh = SchoolHouse() >>> sh.build("roof", "walls") I am building a schoolhouse! I am building a house! I am building a structure! So I'm wondering -- what happened to the School class? Is there any way to get Python to run both somehow? I'm wondering specifically because there are a fair number of Django packages out there that provide custom Managers for models. But there doesn't appear to be a way to combine them without writing one or the other of the Managers as inheriting from the other one. It'd be nice to just import both and use both somehow, but looks like it can't be done? Also I guess it'd just help to be pointed to a good primer on multiple inheritance in Python. I have done some work with Mixins before and really enjoy using them. I guess I just wonder if there is any elegant way to combine functionality from two different classes when they inherit from the same base class.

  • Using JMX classes to notify on events over time

    - by Cincinnati Joe
    I've been looking at JMX for monitoring application and system metrics (partially because MBeans can accessed by various tools such as JConsole). It would seem like the classes included with JMX would be useful for things like notification when metrics have exceeded thresholds. But I'm not sure they fit with the way I want to measure these over a specified time period. For example, let's say I want to notify an admin when the average CPU load is over 95% for more than 5 minutes. Is that something can be done with a GaugeMonitor? From the docs, it doesn't seem quite suited for this, and I'm wondering if instead I should write my own MBean with the necessary logic. A more relevant example is when the login times for users exceed 10s over a period of 5 mins. Slightly different would be the last 20 logins took more than 10s on average. Another case would be when a process crashes 4+ times in an hour. Or the request queue exceeds 15 for 5 mins. Are the JMX Monitor classes useful for this kind of thing?

  • Duplicate C# web service proxy classes generated for Java types

    - by Sergey
    My question is about integration between a Java web service and a C# .NET client. Service: CXF 2.2.3 with Aegis databinding Client: C#, .NET 3.5 SP1 For some reason Visual Studio generates two C# proxy enums for each Java enum. The generated C# classes do not compile. For example, this Java enum: public enum SqlDialect { GENERIC, SYBASE, SQL_SERVER, ORACLE; } Produces this WSDL: <xsd:simpleType name="SqlDialect"> <xsd:restriction base="xsd:string"> <xsd:enumeration value="GENERIC" /> <xsd:enumeration value="SYBASE" /> <xsd:enumeration value="SQL_SERVER" /> <xsd:enumeration value="ORACLE" /> </xsd:restriction> </xsd:simpleType> For this WSDL Visual Studio generates two partial C# classes (generated comments removed): [System.CodeDom.Compiler.GeneratedCodeAttribute("System.Runtime.Serialization", "3.0.0.0")] [System.Runtime.Serialization.DataContractAttribute(Name="SqlDialect", Namespace="http://somenamespace")] public enum SqlDialect : int { [System.Runtime.Serialization.EnumMemberAttribute()] GENERIC = 0, [System.Runtime.Serialization.EnumMemberAttribute()] SYBASE = 1, [System.Runtime.Serialization.EnumMemberAttribute()] SQL_SERVER = 2, [System.Runtime.Serialization.EnumMemberAttribute()] ORACLE = 3, } [System.CodeDom.Compiler.GeneratedCodeAttribute("System.Xml", "2.0.50727.3082")] [System.SerializableAttribute()] [System.Xml.Serialization.XmlTypeAttribute(Namespace="http://somenamespace")] public enum SqlDialect { GENERIC, SYBASE, SQL_SERVER, ORACLE, } The resulting C# code does not compile: The namespace 'somenamespace' already contains a definition for 'SqlDialect' I will appreciate any ideas...
