  • java.lang.IllegalStateException: missing behavior definition for the preceding method call getMessag

    - by user362199
    Hi All, I'm using EasyMock(version 2.4) and TestNG for writing UnitTest. I have a following scenario and I cannot change the way class hierarchy is defined. I'm testing ClassB which is extending ClassA. ClassB look like this public class ClassB extends ClassA { public ClassB() { super("title"); } @Override public String getDisplayName() { return ClientMessages.getMessages("ClassB.title"); } } ClassA code public abstract class ClassA { private String title; public ClassA(String title) { this.title = ClientMessages.getMessages(title); } public String getDisplayName() { return this.title; } } ClientMessages class code public class ClientMessages { private static MessageResourse messageResourse; public ClientMessages(MessageResourse messageResourse) { this.messageResourse = messageResourse; } public static String getMessages(String code) { return messageResourse.getMessage(code); } } MessageResourse Class code public class MessageResourse { public String getMessage(String code) { return code; } } Testing ClassB import static org.easymock.classextension.EasyMock.createMock; import org.easymock.classextension.EasyMock; import org.testng.Assert; import org.testng.annotations.Test; public class ClassBTest { private MessageResourse mockMessageResourse = createMock(MessageResourse.class); private ClassB classToTest; private ClientMessages clientMessages; @Test public void testGetDisplayName() { EasyMock.expect(mockMessageResourse.getMessage("ClassB.title")).andReturn("someTitle"); clientMessages = new ClientMessages(mockMessageResourse); classToTest = new ClassB(); Assert.assertEquals("someTitle" , classToTest.getDisplayName()); EasyMock.replay(mockMessageResourse); } } When I'm running this this test I'm getting following exception: java.lang.IllegalStateException: missing behavior definition for the preceding method call getMessage("title") While debugging what I found is, it's not considering the mock method call mockMessageResourse.getMessage("ClassB.title") as it has been called from the construtor (ClassB object creation). Can any one please help me how to test in this case. Thanks.

  • Project ideas for automated deduction/automated theorem proving?

    - by wsh
    Dear Stack Overflow brethren, I'm a second-semester junior who will embark upon my thesis soon, and I have an interest in automated deduction and automated theorem provers. As in, I'd like to advance the art in some way (I don't mean that pretentiously, but I do want to do something productive). I've Googled pretty far and wide and so far few promising ideas have emerged. There are a few student project idea pages, but most seem either horribly outdated or too advanced (I was originally going to attempt to synthesize postmodernist thought (hahaha) and abstract its logical content, build a complete and consistent model (if possible, of course), and attempt to automate it, grounding said model as possible in a nonstandard logic a la these. My advisor thought that gave postmodernist thought too much credit (a while ago I reimplemented the Postmodernism Generator in Haskell with Parsec, so that is in part where the idea came from); I am tempted to concur.) So, yeah. Does anyone have ideas? I apologize if there is some obvious gap in my approach here/if I haven't appropriately done my homework (and if there is one, please tell me!), but in large part I don't even know where to start, and thank you for reading all that.

  • Is there any special tool for interactive GUI development

    - by niko
    Hi, Currently I am preparing exercises about networks and mobile communications for students. I was thinking about creating an interactive user-interface which enables the user to drag&drop predefined elements and then implement a logic based upon element distances etc. An example would be to place two base stations (a predefined element with several properties), set the scale in the interface and then check the signal interferrence in the environment (user-interface). The first part might be too abstract whereas the example might be too specific, but I was wondering whether there already exists any friendly framework or language which enables developers to create interactive interfaces (for teaching/learning purpouses) in short ammount of time. Usually I write applications for PC environment in .NET but in this case it would take too much time to create a specific interface for every exercise. I would appreciate if anyone could suggest any way to create interactive user-interface in short ammount of time. Are there any special programming languages or development tools for this kind of applications or are there any useful frameworks for .NET, Java or any other language to speed up the development of user-interfaces? Thank you!

  • How do you marshall a parameterized type with JAX-WS / JAXB?

    - by LES2
    Consider the following classes (please assume public getter and setter methods for the private fields). // contains a bunch of properties public abstract class Person { private String name; } // adds some properties specific to teachers public class Teacher extends Person { private int salary; } // adds some properties specific to students public class Student extends Person { private String course; } // adds some properties that apply to an entire group of people public class Result<T extends Person> { private List<T> group; private String city; // ... } We might have the following web service implementation annotated as follows: @WebService public class PersonService { @WebMethod public Result<Teacher> getTeachers() { ... } @WebMethod public Result<Student> getStudents() { ... } } The problem is that JAXB appears to marshall the Result object as a Result<Person> instead of the concrete type. So the Result returned by getTeachers() is serialized as containing a List<Person> instead of List<Teacher>, and the same for getStudents(), mutatis mutandis. Is this the expected behavior? Do I need to use @XmlSeeAlso on Person? Thanks! LES

  • .NET WF4: Should it be in the middle of everything?

    - by stimpy77
    I am aware that WF4 (Windows Workflow 4.0, part of .NET 4.0) is a significant rework and redesign of WF3, where much of what made WF3 a poor technology choice has been cleaned up in WF4. For example, as far as I can tell, WF4 (Windows Workflow 4.0) activities are more or less testable with [TestMethod] and mocking. This among other things, like improved performance, has grabbed my attention about the technology again, whereas I had previously pooh-poohed WF3. I'm working on a new architecture for essentially an n-tier collaborative application (not enterprise-class, just a smallish project with potential to grow significantly) where I'm already trying to discipline myself to use IoC and, to some extent, TDD, and I'm wondering, in general terms, whether it is wiser to just hand-code workflow logic or if I should delve into learning and integrating WF4 so that WF becomes literally the controller of the entire application, i.e. the practical C in "MVC" (not ASP.NET MVC but rather the pattern). So should workflow activities in WF4 be the primary controller for a highly expandable/growable web-based collaborative application? Or am I asking entirely the wrong question? This is a vague question, I'm sure, so abstract answers are as welcome as specific ones.

  • Custom ASPNetMembership FailureInformation always null, OnValidatingPassword issue

    - by bigb
    As stated here http://msdn.microsoft.com/en-us/library/system.web.security.membershipprovider.onvalidatingpassword.aspx "When the ValidatingPassword event has completed, the properties of the ValidatePasswordEventArgs object supplied as the e parameter can be examined to determine whether the current action should be canceled and if a particular Exception, stored in the FailureInformation property, should be thrown." Here is some details/code which really shows why FailureInformation shouldn't be always null http://forums.asp.net/t/991002.aspx if any password security conditions not matched. According with my Membership settings i should get an exception that password does not match password security conditions, but it is not happened. Then i did try to debug System.Web.ApplicationServices.dll(in .NET 4.0 System.Web.Security located here) Framework Code to see whats really happens there, but i cant step into this assembly, may be because of this [TypeForwardedFrom("System.Web, Version=2.0.0.0, Culture=Neutral, PublicKeyToken=b03f5f7f11d50a3a")] public abstract class MembershipProvider : ProviderBase Easily i may step into any another .NET 4.0 assembly, but in this one not. I did check, symbols for System.Web.ApplicationServices.dll loaded. Now i have only one idea how ti fix it - to override method OnValidatingPassword(ValidatePasswordEventArgs e). Thats my story. May be some one may help: 1) Any ideas why OnValidatingPassword not working? 2) Any ideas how to step into it?

  • Error CS0117: Namespace.A does not contain definition for Interface..

    - by SnOrfus
    I'm getting the error: 'Namespace.A' does not contain a definition for 'MyObjectInterface' and no extension method 'MyObjectInterface' accepting a first argument of type ... I've looked at this and this and neither seems to apply. The code looks like: public abstract class Base { public IObject MyObjectInterface { get; set; } } public class A : Base { /**/ } public class Implementation { public void Method() { Base obj = new A(); obj.MyObjectInterface = /* something */; // Error here } } IObject is defined in a separate assembly, but: IObject is in a separate assembly/namespace Base and A are in the same assembly/namespace each with correct using directives Implementation is in a third separate assembly namespace, also with correct using directives. Casting to A before trying to set MyObjectInterface doesn't work Specifically, I'm trying to set the value of MyObjectInterface to a mock object (though, I created a fake instead to no avail) I've tried everything I can think of. Please help before I lose more hair. edit I can't reproduce the error by creating a test app either, which is why I'm here and why I'm frustrated. @Reed Copsey: /* something */ is either an NUnit.DynamicMock(IMailer).MockInstance or a Fake object I created that inherits from IObject and just returns canned values. @Preet Sangha: I checked and no other assembly that is referenced has a definition for an IObject (specifically, it's called an IMailer). Thing is that intellisense picks up the Property, but when I compile, I get CS0117. I can even 'Go To Definition' in the implementation, and it takes me to where I defined it.

  • Having trouble with extension methods for byte arrays

    - by Dave
    I'm working with a device that sends back an image, and when I request an image, there is some undocumented information that comes before the image data. I was only able to realize this by looking through the binary data and identifying the image header information inside. I've been able to make everything work fine by writing a method that takes a byte[] and returns another byte[] with all of this preamble "stuff" removed. However, what I really want is an extension method so I can write image_buffer.RemoveUpToByteArray(new byte[] { 0x42, 0x4D }); instead of byte[] new_buffer = RemoveUpToByteArray( image_buffer, new byte[] { 0x42, 0x4D }); I first tried to write it like everywhere else I've seen online: public static class MyExtensionMethods { public static void RemoveUpToByteArray(this byte[] buffer, byte[] header) { ... } } but then I get an error complaining that there isn't an extension method where the first parameter is a System.Array. Weird, everyone else seems to do it this way, but okay: public static class MyExtensionMethods { public static void RemoveUpToByteArray(this Array buffer, byte[] header) { ... } } Great, that takes now, but still doesn't compile. It doesn't compile because Array is an abstract class and my existing code that gets called after calling RemoveUpToByteArray used to work on byte arrays. I could rewrite my subsequent code to work with Array, but I am curious -- what am I doing wrong that prevents me from just using byte[] as the first parameter in my extension method?

  • Castle ActiveRecord / NHibernate Linq Querys with ValueTypes

    - by Thomas Schreiner
    Given the following code for our Active Record Entites and ValueTypes Linq is not working for us. [ActiveRecord("Person")] public class PersonEntity : ActiveRecordLinqBase<PersonEntity> { string _name; [Property("Name", Length = 20, ColumnType = "string", Access = PropertyAccess.FieldCamelcaseUnderscore)] public Name Name { get { return NameValue.Create(_name);} set { _name = value.DataBaseValue; } } ... } public abstract class Name : IValueType { string DataBaseValue {get;set;} ... } public class Namevalue : Name { string _name; private NameValue(string name) { _name = name; } public static NameValue Create(string name) { return new NameValue(name); } ... } We tried to use linq in the following way so far with no success: var result = from PersonEntity p in PersonEntity.Queryable where p.Name == "Thomas" select p; return result.First(); // throws exception Cannot convert string into Name We tried and implemented a TypeConverter for Name, but the converter never got called. Is there a way to have linq working with this ValueTypes? Update: Using NHibernate.UserTypes.IUserType it sortof works. I Implemented the Interface as described here: http://stackoverflow.com/questions/1565056/how-to-implement-correctly-iusertype I still had to add a ConversionOperator from string to Name and had to call it Explicitly in the linq Statement, even though it was defined as implicit. var result = from PersonEntity p in PersonEntity.Queryable where p.Name == (Name)"Thomas" select p; return result.First(); //Now works

  • CSS compilers and converting IE hacks to conditional css

    - by xckpd7
    Skip to bottom for question, but first, a little context. So I have been looking into CSS compilers (like Sass & Less) for a while, and have been really interested in them, not because they help me understand anything easier (I've been doing css for a couple of years now) but rather they cut down on cruft and help me see things easier. I recently have been looking into reliably implementing inline-block (and clearfix), which require lots of extraneous code & hacks. Now according to all the authorities in the field, I shouldn't put IE hacks in the same page I do my CSS in, I should make them conditional. But for me that is a really big hassle to go through and manage all this additional code, which is why I really like things like Less. Instead of applying unsemantic classes, you specify a mixin and apply it once, and you're all set. So I guess I got a little of the track (I wanted to explain my points) but bascially, I'm at the point where these CSS compilers are very useful for me, and allow me to abstract a lot of the cruft away, and reliably apply them once and then just compile it. I would like to have a way to be able to compile IE specific styles into their own conditional files (ala Less / Sass) so I don't have to deal with managing 2 files for no reason. Does anything like a script/applcation that runs and can make underscore / star hacks apart of their own file exist?

  • Typecasting EnityObject

    - by AJ
    Hello, I'm new to C# and am stuck on the following. I have a Silverlight web service that uses LINQ to query a ADO.NET entity object. e.g.: [OperationContract] public List<Customer> GetData() { using (TestEntities ctx = new TestEntities()) { var data = from rec in ctx.Customer select rec; return data.ToList(); } } This works fine, but what I want to do is to make this more abstract. The first step would be to return a List<EntityObject> but this gives a compiler error, e.g.: [OperationContract] public List<EntityObject> GetData() { using (TestEntities ctx = new TestEntities()) { var data = from rec in ctx.Customer select rec; return data.ToList(); } } The error is: Error 1 Cannot implicitly convert type 'System.Collections.Generic.List<SilverlightTest.Web.Customer>' to 'System.Collections.Generic.IEnumerable<System.Data.Objects.DataClasses.EntityObject>'. An explicit conversion exists (are you missing a cast?) What am i doing wrong? Thanks, AJ

  • Rendering LaTeX on third-party websites

    - by A. Rex
    There are some sites on the web that render LaTeX into some more readable form, such as Wikipedia, some Wordpress blogs, and MathOverflow. They may use images, MathML, jsMath, or something like that. There are other sites on the web where LaTeX appears inline and is not rendered, such as the arXiv, various math forums, or my email. In fact, it is quite common to see an arXiv paper's abstract with raw LaTeX in it, e.g. this paper. Is there a plugin available for Firefox, or would it be possible to write one, that renders LaTeX within pages that do not provide a rendering mechanism themselves? Some notes: It may be impossible to render some of the code, because authors often copy-paste code directly from their source TeX files, which may contain things like "\cite{foo}" or undefined commands. These should be left alone. This question is a repost of a question from MathOverflow that was closed for not being related to math. I program a lot, but Javascript is not my specialty, so comments along the lines of "look at this library" are not particularly helpful to me (but may be to others).

  • ObjC: Alloc instance of Class and performing selectors on it leads to __CFRequireConcreteImplementat

    - by Arakyd
    Hi, I'm new to Objective-C and I'd like to abstract my database access using a model class like this: @interface LectureModel : NSMutableDictionary { } -(NSString*)title; -(NSDate*)begin; ... @end I use the dictionary methods setValue:forKey: to store attributes and return these in the getters. Now I want to read these models from a sqlite database by using the Class dynamically. + (NSArray*)findBySQL:(NSString*)sql intoModelClass:(Class)modelClass { NSMutableArray* models = [[[NSMutableArray alloc] init] autorelease]; sqlite3* db = sqlite3_open(...); sqlite3_stmt* result = NULL; sqlite3_prepare_v2(db, [sql UTF8String], -1, &result, NULL); while(sqlite3_step(result) == SQLITE_ROW) { id modelInstance = [[modelClass alloc] init]; for (int i = 0; i < sqlite3_column_count(result); ++i) { NSString* key = [NSString stringWithUTF8String:sqlite3_column_name(result, i)]; NSString* value = [NSString stringWithUTF8String:(const char*)sqlite3_column_text(result, i)]; if([modelInstance respondsToSelector:@selector(setValue:forKey:)]) [modelInstance setValue:value forKey:key]; } [models addObject:modelInstance]; } sqlite3_finalize(result); sqlite3_close(db); return models; } Funny thing is, the respondsToSelector: works, but if I try (in the debugger) to step over [modelInstance setValue:value forKey:key], it will throw an exception, and the stacktrace looks like: #0 0x302ac924 in ___TERMINATING_DUE_TO_UNCAUGHT_EXCEPTION___ #1 0x991d9509 in objc_exception_throw #2 0x302d6e4d in __CFRequireConcreteImplementation #3 0x00024d92 in +[DBManager findBySQL:intoModelClass:] at DBManager.m:114 #4 0x0001ea86 in -[FavoritesViewController initializeTableData:] at FavoritesViewController.m:423 #5 0x0001ee41 in -[FavoritesViewController initializeTableData] at FavoritesViewController.m:540 #6 0x305359da in __NSFireDelayedPerform #7 0x302454a0 in CFRunLoopRunSpecific #8 0x30244628 in CFRunLoopRunInMode #9 0x32044c31 in GSEventRunModal #10 0x32044cf6 in GSEventRun #11 0x309021ee in UIApplicationMain #12 0x00002988 in main at main.m:14 So, what's wrong with this?

  • How to make Fluent NHibernate ignore Dictionary properties

    - by Matt Winckler
    I'm trying to make Fluent NHibernate's automapping ignore a Dictionary property on one of my classes, but Fluent is ignoring me instead. Ignoring other types of properties seems to work fine, but even after following the documentation and adding an override for the Dictionary, I still get the following exception when BuildSessionFactory is called: The type or method has 2 generic parameter(s), but 1 generic argument(s) were provided. A generic argument must be provided for each generic parameter. I've tried overriding by property name: .Override<MyClass>(map => { map.IgnoreProperty(x => x.MyDictionaryProperty); }) and also tried implementing ignores using a custom attribute, both of which result in the same exception from BuildSessionFactory. The only thing so far that makes this exception go away is removing the Dictionary property entirely. My question seems to be identical to this one which was never answered (though I'll expand the scope by stating it doesn't matter whether the dictionary is on an abstract base class; the problem always happens for me regardless of what class the property is on). Any takers this time around?

  • F# Active Pattern List.filter or equivalent

    - by akaphenom
    I have a records of types type tradeLeg = { id : int ; tradeId : int ; legActivity : LegActivityType ; actedOn : DateTime ; estimates : legComponents ; entryType : ShareOrDollarBased ; confirmedPrice: DollarsPerShare option; actuals : legComponents option ; type trade = { id : int ; securityId : int ; ricCode : string ; tradeActivity : TradeType ; enteredOn : DateTime ; closedOn : DateTime ; tradeLegs : tradeLeg list ; } Obviously the tradeLegs are a type off of a trade. A leg may be settled or unsettled (or unsettled but price confirmed) - thus I have defined the active pattern: let (|LegIsSettled|LegIsConfirmed|LegIsUnsettled|) (l: tradeLeg) = if Helper.exists l.actuals then LegIsSettled elif Helper.exists l.confirmedPrice then LegIsConfirmed else LegIsUnsettled and then to determine if a trade is settled (based on all legs matching LegIsSettled pattern: let (|TradeIsSettled|TradeIsUnsettled|) (t: trade) = if List.exists ( fun l -> match l with | LegIsSettled -> false | _ -> true) t.tradeLegs then TradeIsSettled else TradeIsUnsettled I can see some advantages of this use of active patterns, however i would think there is a more efficient way to see if any item of a list either matches (or doesn't) an actie pattern without having to write a lambda expression specifically for it, and using List.exist. Question is two fold: is there a more concise way to express this? is there a way to abstract the functionality / expression (fun l - match l with | LegIsSettled - false | _ - true) Such that let itemMatchesPattern pattern item = match item with | pattern -> true | _ -> false such I could write (as I am reusing this design-pattern): let curriedItemMatchesPattern = itemMatchesPattern LegIsSettled if List.exists curriedItemMatchesPattern t.tradeLegs then TradeIsSettled else TradeIsUnsettled Thoughts?

  • How do I compose an existing Moose role into a class at runtime?

    - by Oesor
    Say I define an abstract My::Object and concrete role implementations My::Object::TypeA and My::Object::TypeB. For maintainability reasons, I'd like to not have a hardcoded table that looks at the object type and applies roles. As a DWIMmy example, I'm looking for something along these lines in My::Object: has => 'id' (isa => 'Str', required => 1); sub BUILD { my $self = shift; my $type = $self->lookup_type(); ## Returns 'TypeB' {"My::Object::$type"}->meta->apply($self); } Letting me get a My::Object with My::Object::TypeB role applied by doing the following: my $obj = My::Object(id = 'foo') Is this going to do what I want or am I on the entirely wrong track? Edit: I simplified this too much; I don't want to have to know the type when I instantiate the object, I want the object to determine its type and apply the correct role's methods appropriately. I've edited my question to make this clearer.

  • Read a buffer of unknown size (Console input)

    - by Sanarothe
    Hi. I'm a little behind in my X86 Asm class, and the book is making me want to shoot myself in the face. The examples in the book are insufficient and, honestly, very frustrating because of their massive dependencies upon the author's link library, which I hate. I wanted to learn ASM, not how to call his freaking library, which calls more of his library. Anyway, I'm stuck on a lab that requires console input and output. So far, I've got this for my input: input PROC INVOKE ReadConsole, inputHandle, ADDR buffer, Buf - 2, ADDR bytesRead, 0 mov eax,OFFSET buffer Ret input EndP I need to use the input and output procedures multiple times, so I'm trying to make it abstract. I'm just not sure how to use the data that is set to eax here. My initial idea was to take that string array and manually crawl through it by adding 8 to the offset for each possible digit (Input is integer, and there's a little bit of processing) but this doesn't work out because I don't know how big the input actually is. So, how would you swap the string array into an integer that could be used? Full code: (Haven't done the integer logic or the instruction string output because I'm stuck here.) include c:/irvine/irvine32.inc .data inputHandle HANDLE ? outputHandle HANDLE ? buffer BYTE BufSize DUP(?),0,0 bytesRead DWORD ? str1 BYTE "Enter an integer:",0Dh, 0Ah str2 BYTE "Enter another integer:",0Dh, 0Ah str3 BYTE "The higher of the two integers is: " int1 WORD ? int2 WORD ? int3 WORD ? Buf = 80 .code main PROC call handle push str1 call output call input push str2 call output call input push str3 call output call input main EndP larger PROC Ret larger EndP output PROC INVOKE WriteConsole Ret output EndP handle PROC USES eax INVOKE GetStdHandle, STD_INPUT_HANDLE mov inputHandle,eax INVOKE GetStdHandle, STD_INPUT_HANDLE mov outputHandle,eax Ret handle EndP input PROC INVOKE ReadConsole, inputHandle, ADDR buffer, Buf - 2, ADDR bytesRead, 0 mov eax,OFFSET buffer Ret input EndP END main

  • Trying to debug a 'Assertion failure in -[UIActionSheet showInView:]' error....

    I am working through "Beginning iPad Application Development" and am getting hung up in Chapter 3 where I have created a project that works with an Action Sheet. As it stands now, my application loads into the simulator just fine with no errors that I am aware of, but as it runs, it crashes with the following errors showing up in the debugger window: 2010-05-31 19:44:39.703 UsingViewsActionSheet[49538:207] * Assertion failure in -[UIActionSheet showInView:], /SourceCache/UIKit_Sim/UIKit-1145.66/UIAlert.m:7073 2010-05-31 19:44:39.705 UsingViewsActionSheet[49538:207] * Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Invalid parameter not satisfying: view != nil' I am sure that this is the block where the app breaks based upon my use of breakpoints. //Implement viewDidLoad to do additional setup after loading the view, typically from a nib. - (void)viewDidLoad { UIActionSheet *action = [[UIActionSheet alloc] initWithTitle:@"This is my Action Sheet!" delegate:self cancelButtonTitle:@"OK" destructiveButtonTitle:@"Delete Message!" otherButtonTitles:@"Option 1", @"Option 2", @"Option 3", nil]; [action showInView:self.view]; // <-- This line seems to trigger the crash....

  • Testing a method that sends e-mail without sending the mail

    I have a method like public abstract class Base { public void MethodUnderTest(); } public class ClassUnderTest : Base { public override MethodUnderTest() { if(condition) { IMail mail = new Mail() { /* ... */ }; IMailer mailer = new Mailer() { /* ... */ } mailer.Send(mail); } else { /* ... */ } } } I have unit tests for this method, and the mail gets sent to myself, so it's not terrible (better than no test) but I'd prefer not to send the mail. The problem I have is that I don't want test specific code in the class (ie. if (testMode) return; instead of sending the mail) I don't know lots about DI, but I considered passing a mock IMailer into MethodUnderTest except that it overrides the base class, and no other class that derives from Base needs an IMailer object (I don't want to force implementers of Base to take an unnecessary IMailer in MethodUnderTest) What else can I do? (note: IMail and IMailer are part of an external library for sending e-mail. It's written in house, so I can modify it all I like if necessary, though I can't see a need to in this situation)

  • Extend base type and automatically update audit information on Entity

    - by Nix
    I have an entity model that has audit information on every table (50+ tables) CreateDate CreateUser UpdateDate UpdateUser Currently we are programatically updating audit information. Ex: if(changed){ entity.UpdatedOn = DateTime.Now; entity.UpdatedBy = Environment.UserName; context.SaveChanges(); } But I am looking for a more automated solution. During save changes, if an entity is created/updated I would like to automatically update these fields before sending them to the database for storage. Any suggestion on how i could do this? I would prefer to not do any reflection, so using a text template is not out of the question. A solution has been proposed to override SaveChanges and do it there, but in order to achieve this i would either have to use reflection (in which I don't want to do ) or derive a base class. Assuming i go down this route how would I achieve this? For example EXAMPLE_DB_TABLE CODE NAME --Audit Tables CREATE_DATE CREATE_USER UPDATE_DATE UPDATE_USER And if i create a base class public abstract class IUpdatable{ public virtual DateTime CreateDate {set;} public virtual string CreateUser { set;} public virtual DateTime UpdateDate { set;} public virtual string UpdateUser { set;} } The end goal is to be able to do something like... public overrride void SaveChanges(){ //Go through state manager and update audit infromation //FOREACH changed entity in state manager if(entity is IUpdatable){ //If state is created... update create audit. //if state is updated... update update audit } } But I am not sure how I go about generating the code that would extend the interface.

  • IoC & Interfaces Best Practices

    - by n8wrl
    I'm experimenting with IoC on my way to TDD by fiddling with an existing project. In a nutshell, my question is this: what are the best practices around IoC when public and non-public methods are of interest? There are two classes: public abstract class ThisThingBase { public virtual void Method1() {} public virtual void Method2() {} public ThatThing GetThat() { return new ThatThing(this); } internal virtual void Method3() {} internal virtual void Method4() {} } public class Thathing { public ThatThing(ThisThingBase thing) { m_thing = thing; } ... } ThatThing does some stuff using its ThisThingBase reference to call methods that are often overloaded by descendents of ThisThingBase. Method1 and Method2 are public. Method3 and Method4 are internal and only used by ThatThings. I would like to test ThatThing without ThisThing and vice-versa. Studying up on IoC my first thought was that I should define an IThing interface, implement it by ThisThingBase and pass it to the ThatThing constructor. IThing would be the public interface clients could call but it doesn't include Method3 or Method4 that ThatThing also needs. Should I define a 2nd interface - IThingInternal maybe - for those two methods and pass BOTH interfaces to ThatThing?

  • WPF Designer has bug with parsing generic control with overrided property

    - by Ivan Laktyunkin
    I've created a generic lookless control with virtual property: public abstract class TestControlBase<TValue> : Control { public static readonly DependencyProperty ValueProperty; static TestControlBase() { ValueProperty = DependencyProperty.Register("Value", typeof(TValue), typeof(TestControlBase<TValue>)); } protected TestControlBase() { Focusable = false; Value = default(TValue); } public virtual TValue Value { get { return (TValue)GetValue(ValueProperty); } set { SetValue(ValueProperty, value); } } } Then I've made a control derived from it and overrided Value property: public class TestControl : TestControlBase<int> { public override int Value { get { return base.Value; } set { base.Value = value; } } } So I use it in a Window XAML: <TestControls:TestControl /> When I open window in designer all is OK, but when I put mouse cursor to this line, or to this control in designer I receive exception: Exception has been thrown by the target of an invocation. at System.RuntimeMethodHandle._InvokeMethodFast(Object target, Object[] arguments, SignatureStruct& sig, MethodAttributes methodAttributes, RuntimeTypeHandle typeOwner) at System.RuntimeMethodHandle.InvokeMethodFast(Object target, Object[] arguments, Signature sig, MethodAttributes methodAttributes, RuntimeTypeHandle typeOwner) at System.Reflection.RuntimeMethodInfo.Invoke(Object obj, BindingFlags invokeAttr, Binder binder, Object[] parameters, CultureInfo culture, Boolean skipVisibilityChecks) at System.Delegate.DynamicInvokeImpl(Object[] args) at System.Windows.Threading.ExceptionWrapper.InternalRealCall(Delegate callback, Object args, Boolean isSingleParameter) at System.Windows.Threading.ExceptionWrapper.TryCatchWhen(Object source, Delegate callback, Object args, Boolean isSingleParameter, Delegate catchHandler) Ambiguous match found. at System.RuntimeType.GetPropertyImpl(String name, BindingFlags bindingAttr, Binder binder, Type returnType, Type[] types, ParameterModifier[] modifiers) at System.Type.GetProperty(String name) at MS.Internal.ComponentModel.DependencyPropertyKind.get_IsDirect() at MS.Internal.ComponentModel.DependencyPropertyKind.get_IsAttached() at MS.Internal.ComponentModel.APCustomTypeDescriptor.GetProperties(Attribute[] attributes) at MS.Internal.ComponentModel.APCustomTypeDescriptor.GetProperties() at System.ComponentModel.TypeDescriptor.TypeDescriptionNode.DefaultExtendedTypeDescriptor.System.ComponentModel.ICustomTypeDescriptor.GetProperties() at System.ComponentModel.TypeDescriptor.GetPropertiesImpl(Object component, Attribute[] attributes, Boolean noCustomTypeDesc, Boolean noAttributes) at System.ComponentModel.TypeDescriptor.GetProperties(Object component) at MS.Internal.Model.ModelPropertyCollectionImpl.GetProperties(String propertyNameHint) at MS.Internal.Model.ModelPropertyCollectionImpl.<GetEnumerator>d__0.MoveNext() at MS.Internal.Designer.PropertyEditing.Model.ModelPropertyMerger.<GetFirstProperties>d__0.MoveNext() at MS.Internal.Designer.PropertyEditing.PropertyInspector.UpdateCategories(Selection selection) at MS.Internal.Designer.PropertyEditing.PropertyInspector.OnSelectionChangedIdle() Who know this problem? Please explain :) I have no ideas except that WPF Designer doesn't like generics. If I replace generics by Object all is OK.

  • A Django form for entering a 0 to n email addresses

    - by Erik
    I have a Django application with some fairly common models in it: UserProfile and Organization. A UserProfile or an Organization can both have 0 to n emails, so I have an Email model that has a GenericForeignKey. UserProfile and Organization Models both have a GenericRelation called emails that points back to the Email model (summary code provided below). The question: what is the best way to provide an Organization form that allows a user to enter organization details including 0 to n email addresses? My Organization create view is a Django class-based view. I'm leading towards creating a dynamic form and an enabling it with Javascript to allow the user to add as many email addresses as necessary. I will render the form with django-crispy-forms. I've thought about doing this with a formset embedded within the form, but this seems like overkill for email addresses. Embedding a formset in a form delivered by a class-based view is cumbersome too. Note that the same issue occurs with the Organization fields phone_numbers and locations. emails.py: from django.db import models from parent_mixins import Parent_Mixin class Email(Parent_Mixin,models.Model): email_type = models.CharField(blank=True,max_length=100,null=True,default=None,verbose_name='Email Type') email = models.EmailField() class Meta: app_label = 'core' organizations.py: from emails import Email from locations import Location from phone_numbers import Phone_Number from django.contrib.contenttypes import generic from django.db import models class Organization(models.Model): active = models.BooleanField() duns_number = models.CharField(blank=True,default=None,null=True,max_length=9) # need to validate this emails = generic.GenericRelation(Email,content_type_field='parent_type',object_id_field='parent_id') legal_name = models.CharField(blank=True,default=None,null=True,max_length=200) locations = generic.GenericRelation(Location,content_type_field='parent_type',object_id_field='parent_id') name = models.CharField(blank=True,default=None,null=True,max_length=200) organization_group = models.CharField(blank=True,default=None,null=True,max_length=200) organization_type = models.CharField(blank=True,default=None,null=True,max_length=200) phone_numbers = generic.GenericRelation(Phone_Number,content_type_field='parent_type',object_id_field='parent_id') taxpayer_id_number = models.CharField(blank=True,default=None,null=True,max_length=9) # need to validate this class Meta: app_label = 'core' parent_mixins.py from django.contrib.contenttypes.models import ContentType from django.contrib.contenttypes import generic from django.db import models class Parent_Mixin(models.Model): parent_type = models.ForeignKey(ContentType,blank=True,null=True) parent_id = models.PositiveIntegerField(blank=True,null=True) parent = generic.GenericForeignKey('parent_type', 'parent_id') class Meta: abstract = True app_label = 'core'

  • how to store JSON into POJO using Jackson

    - by user2963680
    I am developing a module where i am using rest service to get data. i am not getting how to store JSON using Jackson and store it which has Queryparam also. Any help is really appreciated as I am new to this.I am trying to do server side filtering in extjs infinte grid which is sending the below request to rest service. when the page load first time, it sends http://myhost/mycontext/rest/populateGrid?_dc=9999999999999&page=1&start=0&limit=500 when you select filter on name and place, it sends http://myhost/mycontext/rest/populateGrid?_dc=9999999999999&filter=[{"type":"string","value":"Tom","field":"name"},{"type":"string","value":"London","field":"Location"}]&page=1&start=0&limit=500 I am trying to save this in POJO and then sending this to database to retrieve data. For this on rest side i have written something like this @Provider @Path("/rest") public interface restAccessPoint { @GET @Path("/populateGrid") @Produces({MediaType.APPLICATION_JSON}) public Response getallGridData(FilterJsonToJava filterparam,@QueryParam("page") String page,@QueryParam("start") String start,@QueryParam("limit") String limit); } public class FilterJsonToJava { @JsonProperty(value ="filter") private List<Filter> data; .. getter and setter below } public class Filter { @JsonProperty("type") private String type; @JsonProperty("value") private String value; @JsonProperty("field") private String field; ...getter and setters below } I am getting the below error The following warnings have been detected with resource and/or provider classes: WARNING: A HTTP GET method, public abstract javax.ws.rs.core.Response com.xx.xx.xx.xxxxx (com.xx.xx.xx.xx.json.FilterJsonToJava ,java.lang.String,java.lang.String,java.lang.String), should not consume any entity. com.xx.xx.xx.xx.json.FilterJsonToJava, and Java type class com.xx.xx.xx.FilterJsonToJava, and MIME media type application/octet-stream was not found [11/6/13 17:46:54:065] 0000001c ContainerRequ E The registered message body readers compatible with the MIME media type are: application/octet-stream com.sun.jersey.core.impl.provider.entity.ByteArrayProvider com.sun.jersey.core.impl.provider.entity.FileProvider com.sun.jersey.core.impl.provider.entity.InputStreamProvider com.sun.jersey.core.impl.provider.entity.DataSourceProvider com.sun.jersey.core.impl.provider.entity.RenderedImageProvider */* -> com.sun.jersey.core.impl.provider.entity.FormProvider ...
