  • Include in enity framework 4

    - by molgan
    Hello I've been using enity framework that came with 3.5sp. And now I've redone things for enityframework 4 and asp.net mvc 2. I've come across something (which worked in my previous version and asp.net mvc 1.0). I have this: public IQueryable<Booking> GetBookings() { return from b in _entities.Bookings.Include("BookingObject") select b; } And in my controller I have: return View("Index", new BookingsViewModel { Bookings = _br.GetBookings().ByDay(DateTime.Today) }); And it doesnt seem to include the "BookingObject"-entity, so I can type like <%= Model.Bookings.BookingObject.BookingObjectName %> in my view. What might be missing here? Do I need to turn something on in the diagram for it to include entities or? /M

  • how to avoid repeating code?

    - by helloWorld
    I have some technical question, I have repeating code in my work, and I want to get rid of it, so I know that in C++ it is not good idea to use macro, but instead I must use inline function, is it good idea to use this function as inline: list<Data>::iterator foo(int data){ if(dataExists(data)){ list<Data>::iterator i; for(i = Data.begin(); i != Data.end(); ++i){ if(i->getData() == data){ break; } return i; //here I have one more problem, what can I return if data doesn't exist? } I'm beginner, and I think that this function is very unsafe, can somebody please give me advice, how can I improve my code, thanks in advance P.S. what usually do You use to avoid repeating code?

  • populating on the basis of array elements in php

    - by Avinash
    This is my code. if(in_array("1", $mod)){ $res=array('First Name','Insertion','Last Name','Lead Country');} if(in_array("2", $mod)){ $res=array('Landline No:','Mobile No:','Lead Country');} if(in_array("3", $mod)){ $res=array('City','State','Country','Lead Country');} if(in_array("4", $mod)){ $res=array('Email','Lead Country');} return $res; Upto this it works fine. But if the array contains more than one value say (1,3) I need to return both results of 1 and 3. eg: if the array is like this array([0]=>1 [1]=>3) then $res=array('First Name','Insertion','Last Name','City','State','Country','Lead Country') But if there are 2 lead country only one should be displayed how to do this? Pls help me.

  • Is base method able to use derived base data members?

    - by iTayb
    Lets assume we have the following code: abstract class Base1 { protected int num; } class Der1:Base1 { protected Color color; protected string name; } class Der2:Base1 { protected DateTime dthen; } and so on. An array of base1 type exists and includes many objects created out of classes that are derived from base1. Is it possible to define the toString() method in the base class only? something like: public override string toString() { if (this is Der1) return "num = " + this.num + "color = " + this.color.toString() + " name = " this.name; if (this is Der2) return "num = " + this.num + "dthen = " + this.dthen.toString(); // and so on ... } Thank you very much :) P.S. This is not an homework question. I've just wondered about.

My Goal I want to query in orm like this select id,owner from article where id = 4 it's will be return only id & owner, how i can get that using orm ?

  • Reset JPA generated value between tests

    - by Rythmic
    I'm running spring + hibernate + JUnit with springJunit4runner and transactional set to default rollback I'm using in-memory derbydb as Database. Hibernate is used as a JPA Provider and I am successfully testing CRUD kinds of stuff. However, I have a problem with JPA and the behaviour of @GeneratedValue If I run one of my tests in isolation, two entitys are persisted with id 1 and 2. If i run the whole test suite the ids are instead 6 and 7. Spring does rollbacks just fine so there are only these two entitys in the database after addition and of course zero before. But behaviour of @GeneratedValue doesn't allow me to reliable findById unless I would return the Id from the dao.add(Entity e) //method I don't feel like doing that for the sake of testing, or is it a good practise to return the entity that was persisted so I should be doing it anyway?

  • How to give properties to c++ classes (interfaces)

    - by caas
    Hello, I have built several classes (A, B, C...) which perform operations on the same BaseClass. Example: struct BaseClass { int method1(); int method2(); int method3(); } struct A { int methodA(BaseClass& bc) { return bc.method1(); } } struct B { int methodB(BaseClass& bc) { return bc.method2()+bc.method1(); } } struct C { int methodC(BaseClass& bc) { return bc.method3()+bc.method2(); } } But as you can see, each class A, B, C... only uses a subset of the available methods of the BaseClass and I'd like to split the BaseClass into several chunks such that it is clear what it used and what is not. For example a solution could be to use multiple inheritance: // A uses only method1() struct InterfaceA { virtual int method1() = 0; } struct A { int methodA(InterfaceA&); } // B uses method1() and method2() struct InterfaceB { virtual int method1() = 0; virtual int method2() = 0; } struct B { int methodB(InterfaceB&); } // C uses method2() and method3() struct InterfaceC { virtual int method2() = 0; virtual int method3() = 0; } struct C { int methodC(InterfaceC&); } The problem is that each time I add a new type of operation, I need to change the implementation of BaseClass. For example: // D uses method1() and method3() struct InterfaceD { virtual int method1() = 0; virtual int method3() = 0; } struct D { int methodD(InterfaceD&); } struct BaseClass : public A, B, C // here I need to add class D { ... } Do you know a clean way I can do this? Thanks for your help edit: I forgot to mention that it can also be done with templates. But I don't like this solution either because the required interface does not appear explicitly in the code. You have to try to compile the code to verify that all required methods are implemented correctly. Plus, it would require to instantiate different versions of the classes (one for each BaseClass type template parameter) and this is not always possible nor desired.

  • jQuery click listener on <object> in IE failing

    - by Steve Meisner
    $("#listView object.modal").click(function(){ // Get the ID of the clicked link: var link = $(this).closest("h2").attr("title"); var id = $(this).closest("div").attr("id"); showDialog(link, id); return false; }); This fires a modal (jQuery UI). It it working in FF, Chrome/Safari but not in IE 7/8. Is there something I'm missing here? Big Picture: We're using a swf to render custom type and there is a link in the rendered (flash) content. We're hoping to catch the link action in the jQuery listener so we don't have to extend our swf have an optional param to return false on link click. We thought we got around it, until IE testing commenced... Let me know if any more info is needed. Thanks!

  • Temporarily Disallow JQuery Toggle

    - by Kevin Sylvestre
    I have a menu that is toggled when a user selects a link. The menu has an animation attached, and I want to prevent toggling while the animation is running. The following snippet works, but flips the state of toggle if the link is clicked quickly twice (i.e. if the user clicks the link quickly twice, the next click will trigger the same action): <a href="" id="button">Menu</a> <div id="menu">...</a> <script> $("#button").toggle( function (e) { if $("#menu").is(":animated")) return false; $menu.show("slow"); }, function (e) { if ("#menu").is(":animated")) return false; $menu.hide("slow"); } ); </script> How can I prevent switching states within toggle? Thanks.

  • How to compare two lists with duplicated items in one list?

    - by eladc
    I need to compare list_a against many others. my problem starts when there's a duplicated item in the other lists (two k's in other_b). my goal is to filter out all the lists with the same items (up to three matching items). list_a = ['j','k','a','7'] other_b = ['k', 'j', 'k', 'q'] other_c = ['k','k','9','k'] >>>filter(lambda x: not x in list_a,other_b) ['q'] I need a way that would return ['k', 'q'], because 'k' appears only once in list_a. comparing list_a and other_c with set() isn't good for my purpose since it will return only one element: k. while I need ['k','9','k'] I hope I was clear enough. Thank you

  • Difference Between Two Lists with Many Duplicates in Python

    - by Paul
    I have several lists that contain many of the same items and many duplicate items. I want to check which items in one list are not in the other list. For example, I might have one list like this: l1 = ['a', 'b', 'c', 'b', 'c'] and one list like this: l2 = ['a', 'b', 'c', 'b'] Comparing these two lists I would want to return a third list like this: l3 = ['c'] I am currently using some terrible code that I made a while ago that I'm fairly certain doesn't even work properly shown below. def list_difference(l1,l2): for i in range(0, len(l1)): for j in range(0, len(l2)): if l1[i] == l1[j]: l1[i] = 'damn' l2[j] = 'damn' l3 = [] for item in l1: if item!='damn': l3.append(item) return l3 How can I better accomplish this task?

  • C#: How to unit test a method that relies on another method within the same class?

    - by michael paul
    I have a class similar to the following: public class MyProxy : ClientBase<IService>, IService { public MyProxy(String endpointConfiguration) : base(endpointConfiguration) { } public int DoSomething(int x) { int result = DoSomethingToX(x); //This passes unit testing int result2 = ((IService)this).DoWork(x) //do I have to extract this part into a separate method just //to test it even though it's only a couple of lines? //Do something on result2 int result3 = result2 ... return result3; } int IService.DoWork(int x) { return base.Channel.DoWork(x); } } The problem lies in the fact that when testing I don't know how to mock the result2 item without extracting the part that gets result3 using result2 into a separate method. And, because it is unit testing I don't want to go that deep as to test what result2 comes back as... I'd rather mock the data somehow... like, be able to call the function and replace just that one call.

  • Why does Java ArrayList use per-element casting instead of per-array casting?

    - by user1111929
    What happens inside Java's ArrayList<T> (and probably many other classes) is that there is an internal Object[] array = new Object[n];, to which T Objects are written. Whenever an element is read from it, a cast return (T) array[i]; is done. So, a cast on every single read. I wonder why this is done. To me, it seems like they're just doing unnecessary casts. Wouldn't it be more logical and also slightly faster to just create a T[] array = (T[]) new Object[n]; and then just return array[i]; without cast? This is only one cast per array creation, which is usually far less than the number of reads. Why is their method to be preferred? I fail to see why my idea isn't strictly better?

  • AS3 Passing data between objects/classes

    - by 1337holiday
    So i a building a categorized menu of different foods. I have a class for "categories" (buttons) which essentially will return a string "salads", "drinks", etc. I now have another class "menuItems" for items within categories and this handles sizes such as "small", "med", "large", etc. My problem now is that when i return "salads", i want to invoke an array which contains all the elements of salads, send it to menuItems which will populate the menu. So far i have both the category objects and the menu object setup. I just cant seem to be able to send the data that the category object is returning and pass it to the menu object. Both of which are added to the stage as shown below: If there was a way that i could say add all these classes to one class so that they can talk to each other that would be great but i dont know how to do this. Been stuck for hours, please any help is greatly appreciated.

  • jQuery UI: how to run evaluation

    - by mikkelbreum
    I want to add 'Year' or Years' to the end of a string depending on the string. Like this: $("#selector").val(conditional_value_here); Using jQuery UI I have a slider that manipulates a value: $("#slider").slider({ value: 1, min: 1, max: 25, step: 1, slide: function(event, ui) { $("#amount").val(ui.value + ' Year' + function(){return (ui.value == 1) ? '' : 's';} ); } }); // and again I want to do the same for the initialization of the value: $("#amount_3").val($("#slider_3").slider("value") + ' Jahr' + function(){return ($("#slider_3").slider("value") == 1) ? '' : 's';}); This does not work. What is the correct way to to this?

  • What is the best signature for overloaded arithmetic operators in C++?

    - by JohnMcG
    I had assumed that the canonical form for operator+, assuming the existence of an overloaded operator+= member function, was like this: const T operator+(const T& lhs, const T& rhs) { return T(lhs) +=rhs; } But it was pointed out to me that this would also work: const T operator+ (T lhs, const T& rhs) { return lhs+=rhs; } In essence, this form transfers creation of the temporary from the body of the implementation to the function call. It seems a little awkward to have different types for the two parameters, but is there anything wrong with the second form? Is there a reason to prefer one over the other?

  • Actionscript: Switching back into previous function from event handler function

    - by J.Ded.
    I need to return to my original function after capturing an event (downloading something) with another function. The original function needs to return a value, which depends on the downloaded data. So, I'd like to pause original function for the time needed for the download and the eventhandler function to complete it's work, and resume it afterwards. The obvious way is to set a flag value (both the original function and the eventhandler are within the same class) and make the original function check it until the eventhandler function changes the flag. But that would be wasteful, and my AS is slow enough already:) [other parts of the application utilise some heavy graphics]. Is there another way? Like an event that gets captured "in the middle" of the function? Or some other form of flow control?

  • Is there a Javadoc-like plugin for Xcode that automatically generates the doc template?

    - by Mark
    I'm aware of Doxygen to generate the documentation. What I'm looking for is quick way to insert documentation in Xcode similar to what Eclipse does when editing Java files. Let's say I have an objective-c method with a couple of arguments like this: -(NSInteger*) sumOf: (NSInteger*) one and:(NSInteger*) two {... In Eclipse, if you place the cursor above the method and type: /**<Enter> you get a Javadoc template pre-populated with @param and @return tags. Is it possible to achieve something similar in Xcode? After typing /**<Enter>, I'd like to get this automatically: /** * * @param one * @param two * * @return */ -(NSInteger*) sumOf: (NSInteger*) one and:(NSInteger*) two {...

  • Generate a valid array key from an URL string in PHP

    I have a PHP array with some predefined values: $aArray = array( 0 => 'value0', 1 => 'value1' ); I need to create a function where the string input will always return the same, valid, array key so that when I call: GiveMeAKey('http://www.google.com'); // May return 0 or 1 I receive always the same key (I don't care which one) from the array. Obvisously I can't store the relationship in a database and the string passed to the GiveMeAKey method can be any URL. I wonder if there is a way of doing that ?
