  • fluent nhibernate - storing and retrieving three classes in/from one table

    - by Will I Am
    Noob question. I have this situation where I have these objects: class Address { string Street; string City; ... } class User { string UserID; Address BillingAddress; Address MailingAddress; ... } What is the proper way of storing this data using (fluent) nHibernate? I could use a separate Address table and create a reference, but they are 1:1 relationships so I don't really want to incur the overhead of a join. Ideally I would store this as a single flat record. So, my question is, what is the proper way of storing an instance of class 'User' in such a way that it stores its contents and also the two addresses as a single record? My knowledge is failing me on how I can store this information in such a way that the two Address records get different column names (e.g. BillingAddress_Street and MailingAddress_Street, for example), and also how to read a record back into a User instance.

  • ASP.NET MVC Generic Partial

    - by gnome
    Is is possible to have a partial view inherit more than one model? I have three models (Contacts, Clients, Vendors) that all have address information (Address). In the interest of being DRY I pulled the address info into it's own model, Addresses. I created a partial create / update view of addresses and what to render this in other other three model's create / update views.

  • MySQL: host name universal change.

    - by ctrlShiftBryan
    I am making some updates to a php site which I did not design. I have a local copy of the site. At the top of each page there are settings for the host name for the db connection. Is there someway I can setup a pointer to the remote address. The address is 'mysqlhost' for example and I want that to point to 'mysql.myhost.com'. I tried creating a HOST record for mysqlhost pointing to the IP address it resolves to but that doesn't work. If I put 'mysql.myhost.com' in the connection it works. If I put that IP address it doesn't so that is probably why the HOST record idea doesn't work. Other than creating a local copy of the DB is there a quick way so that I don't have to modify each file in my dev environment and then again when I redeploy?

  • how can I get around no arrays as class constants in php?

    - by user151841
    I have a class with a static method. There is an array to check that a string argument passed is a member of a set. But, with the static method, I can't reference the class property in an uninstantiated class, nor can I have an array as a class constant. I suppose I could hard code the array in the static method, but then if I need to change it, I'd have to remember to change it in two places. I'd like to avoid this.

  • Is this data set in third normal form?

    - by user2980802
    UNF: (Customer-name, Customer-id, Customer-address, (Unit-price, Order-id, Quantity, Product-id, Delivery-date) (Supplier-name, Supplier-id, Supplier-Address) 3NF: CUSTOMER (Customer-id, Order-id, Customer-name, Customer-address) ORDER (Order-id, Customer-id) ORDER/PRODUCT (Order-id, Quantity, Product-id) PRODUCT (Order-id, Product-id, Delivery-date, Supplier-id, Unit-price,) SUPPLIER (Supplier-name, Supplier-id, Supplier-Address, Product-id) Basically, the UNF is the un-normalised form. The information should have EXACTLY five tables, it's a hint we were given. The tables listed are the definite table names. We were told to make assumptions based on this information: Customer Invoice is generated from customer orders (Order & Order/Product entities) Supplier Order is generated for products that are low in stock (Product entity) Assumptions A customer can place many orders but an order is placed by only one customer An order can be for many products and a product can be ordered many times A product is supplied by only one supplier, a supplier may supply many products This is one of my modules in university and my lecturer is all but useful, I'm really struggling so any help is really appreciated.

  • C++0x class factory with variadic templates problem

    - by randomenglishbloke
    I have a class factory where I'm using variadic templates for the c'tor parameters (code below). However, when I attempt to use it, I get compile errors; when I originally wrote it without parameters, it worked fine. Here is the class: template< class Base, typename KeyType, class... Args > class GenericFactory { public: GenericFactory(const GenericFactory&) = delete; GenericFactory &operator=(const GenericFactory&) = delete; typedef Base* (*FactFunType)(Args...); template <class Derived> static void Register(const KeyType &key, FactFunType fn) { FnList[key] = fn; } static Base* Create(const KeyType &key, Args... args) { auto iter = FnList.find(key); if (iter == FnList.end()) return 0; else return (iter->second)(args...); } static GenericFactory &Instance() { static GenericFactory gf; return gf; } private: GenericFactory() = default; typedef std::unordered_map<KeyType, FactFunType> FnMap; static FnMap FnList; }; template <class B, class D, typename KeyType, class... Args> class RegisterClass { public: RegisterClass(const KeyType &key) { GenericFactory<B, KeyType, Args...>::Instance().Register(key, FactFn); } static B *FactFn(Args... args) { return new D(args...); } }; Here is the error: when calling (e.g.) // Tucked out of the way RegisterClass<DataMap, PDColumnMap, int, void *> RC_CT_PD(0); GCC 4.5.0 gives me: In constructor 'RegisterClass<B, D, KeyType, Args>::RegisterClass(const KeyType&) [with B = DataMap, D = PDColumnMap, KeyType = int, Args = {void*}]': no matching function for call to 'GenericFactory<DataMap, int, void*>::Register(const int&, DataMap* (&)(void*))' I can't see why it won't compile and after extensive googling I couldn't find the answer. Can anyone tell me what I'm doing wrong (aside from the strange variable name, which makes sense in context)?

  • JUnit Theories: Why can't I use Lists (instead of arrays) as DataPoints?

    - by MatrixFrog
    I've started using the new(ish) JUnit Theories feature for parameterizing tests. If your Theory is set up to take, for example, an Integer argument, the Theories test runner picks up any Integers marked with @DataPoint: @DataPoint public static Integer number = 0; as well as any Integers in arrays: @DataPoints public static Integer[] numbers = {1, 2, 3}; or even methods that return arrays like: @DataPoints public static Integer[] moreNumbers() { return new Integer[] {4, 5, 6};}; but not in Lists. The following does not work: @DataPoints public static List<Integer> numberList = Arrays.asList(7, 8, 9); Am I doing something wrong, or do Lists really not work? Was it a conscious design choice not to allow the use Lists as data points, or is that just a feature that hasn't been implemented yet? Are there plans to implement it in a future version of JUnit?

  • How do I make this Java code operate properly? [Multi-threaded, race condition]

    - by Fixee
    I got this code from a student, and it does not work properly because of a race condition involving x++ and x--. He added synchronized to the run() method trying to get rid of this bug, but obviously this only excludes threads from entering run() on the same object (which was never a problem in the first place) but doesn't prevent independent objects from updating the same static variable x at the same time. public class DataRace implements Runnable { static volatile int x; public synchronized void run() { for (int i = 0; i < 10000; i++) { x++; x--; } } public static void main(String[] args) throws Exception { Thread [] threads = new Thread[100]; for (int i = 0; i < threads.length; i++) threads[i] = new Thread(new DataRace()); for (int i = 0; i < threads.length; i++) threads[i].start(); for (int i = 0; i < threads.length; i++) threads[i].join(); System.out.println(x); // x not always 0! } } Since we cannot synchronize on x (because it is primitive), the best solution I can think of is to create a new static object like static String lock = ""; and enclose the x++ and x-- within a synchronized block, locking on lock. But this seems really awkward. Is there a better way?

  • LNK4221 and LNK4006 Warnings!

    - by user295030
    Hi, I basically making a static library of my own. I have taken my code which works and now put it into a static library for another program to use. In my library I am using another static library which I don't want the people who will be using my API to know. Since, I want to hide that information from them I can't tell them to install the other static library. Anyway, I used the command line Lib.exe to extract and create a smaller lib file of just the obj's I used. However, I get a bunch of "LNK4006 :second definition ignored" linker warnings for each obj I use followed by "LNK4221 no public symbols found;archive member will be inaccessible". I am doing this work in vs2008 and I am not sure what I am doing wrong. I am using the #pragma comment line in my .cpp file I have also modified the librarian to add my smaller .lib along with its location. my code simply makes calls to a couple functions which it should be able to get from those Obj file in the smaller lib. All my functions are implemented in .cpp file and my header just have the includes of the third party header files and come standard c++ header files. nothing fancy. I have actually no function definitions in there atm. I was going to put the API definition in there and implement that in the .cpp for this static lib that i was going to make. However, I just wanted to build my code before I added more to it. s Any help would be appreciated. is this a vs2008 configuration issue? or a program issue I am not sure. thanks for the help!

  • Where to declare variable? C#

  • java packets byte

    - by user303289
    Guys, I am implementing a protocol in one of the wireless project. I am stucked at one point. In of the java file i am suppose to receive a packet and that packet is 12 byte packet and I have to write different functions for reading different parts of packets and convert it to diferent type. Like I want first four byte in one of the function and convert it to int, next two bytes in string. and again next two in string, last two hop in string and followed by last two int. I want follwing function to implement: // here is the interface /* FloodingData should use methods defined in this class. */ class FloodingPacket{ public static void main(String arg[]){ byte FloodingPack[]; // just for example to test in code FloodingPack=new byte[12]; interface IFloodingPacket { // Returns the unique sequence number for the packet int getSequenceNumber() ; // Returns the source address for the packet String getSourceAddress(); // Returns the destination address for the packet String getDestinationAddress(); // Returns the last hop address for the packet String getLastHopAddress(); // Sets the last hop address to the address of the node // which the packet was received from void updateLastHopAddress(); // Returns the entire packet in bytes (for sending) byte[] getBytes(); // Sets the bytes of the packet (for receiving) void setBytes(byte[] packet); }

  • Reference and Value confusion

    - by rgamber
    Hi I read this question on Stack overflow, and tried to do an example. I had the below code: public static void main(String[] args){ int i = 5; Integer I = new Integer(5); increasePrimitive(i); increaseObject(I); System.out.println(i); //Prints 5 - correct System.out.println(I); //Still prints 5 System.out.println(increaseObject2(I)); //Still prints 5 } public static void increasePrimitive(int n){ n++; } public static void increaseObject(Integer n){ n++; } public static int increaseObject2(Integer n){ return n++; } Does the increaseObject print 5 because the value of reference is changing inside that function? Am I right? I am confused why the increasedObject2 prints 5 and not 6. Can anyone please explain?

  • Magic squares, recursive

    Hi, my problem is, I'm trying to permute all posibilities for a 3x3 square and check if the combination is magic. I've added a tweak with (n%3==0) if statement that if the sum of numbers in row differs from 15 it breaks the creation of other two lines... but it doesn't work. Any suggestions? I call the function with Permute(1). public static class Global { //int[] j = new int[6]; public static int[] a= {0,0,0,0,0,0,0,0,0}; public static int[] b= {0,0,0,0,0,0,0,0,0}; public static int count = 0; } public static void Permute(int n) { int tmp=n-1; for (int i=0;i<9;i++){ if (Global.b[i]==0 ) { Global.b[i]=1; Global.a[n-1]=i+1; if ((n % 3) == 0) { if (Global.a[0+tmp]+Global.a[1+tmp]+Global.a[2+tmp] == 15) { if (n<9) { Permute(n+1); } else { isMagic(Global.a); } } else break; } else { Permute(n+1); } Global.b[i]=0; } } }

  • Three customer addresses in one table or in separate tables?

    - by DR
    In my application I have a Customer class and an Address class. The Customer class has three instances of the Address class: customerAddress, deliveryAddress, invoiceAddress. Whats the best way to reflect this structure in a database? The straightforward way would be a customer table and a separate address table. A more denormalized way would be just a customer table with columns for every address (Example for "street": customer_street, delivery_street, invoice_street) What are your experiences with that? Are there any advantages and disadvantages of these approaches?

  • Applying jQuery attr value to new DOM elements (result of AJAX query)

    - by Daniel
    Hello everyone, I have a div on a page whose contents is replaced by an AJAX request when the user selects an option from a select list. When the page loads, I issue a command to disable the autocomplete feature for all of the pages text input elements: //Stop that pesky browser autocomplete $('input[type=text]').attr("autocomplete", "off"); However, when new elements appear in the div after an AJAX call, this line of code does not reference them because they were not part of the original DOM (when the page was loaded). I have tried appending the autocomplete line to the end of the post function: //AJAX Post request that changes the fields in the address div for each different country $("div#address select#country").live("change", function() { $.post("<?php print($_SERVER['PHP_SELF']); ?>", { country: $(this).val() }, function(data) { $('div#address').html(data); }, "text"); $('div#address input[type=text]').attr("autocomplete", "off"); }); But for some reason it does not work and the autocomplete pops up when text is entered into any of the address fields. As far as I am aware I cannot use .live() to select the input elements because changing an attribute is not classed as an event. So can anyone advise me how to modify the attributes of a newly created DOM element?

  • Using addMouseListener() and paintComponent() for JPanel

    - by Alex
    This is a follow-up to my previous question. I've simplified things as much as I could, and it still doesn't work! Although the good thing I got around using getGraphics(). A detailed explanation on what goes wrong here is massively appreciated. My suspicion is that something's wrong with the the way I used addMouseListener() method here. import java.awt.Color; import java.awt.Graphics; import java.awt.event.MouseAdapter; import java.awt.event.MouseEvent; import javax.swing.JFrame; import javax.swing.JPanel; public class MainClass1{ private static PaintClass22 inst2 = new PaintClass22(); public static void main(String args[]){ JFrame frame1 = new JFrame(); frame1.add(inst2); frame1.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame1.setTitle("NewPaintToolbox"); frame1.setSize(200, 200); frame1.setLocationRelativeTo(null); frame1.setVisible(true); } } class PaintClass11 extends MouseAdapter{ int xvar; int yvar; static PaintClass22 inst1 = new PaintClass22(); public PaintClass11(){ inst1.addMouseListener(this); inst1.addMouseMotionListener(this); } @Override public void mouseClicked(MouseEvent arg0) { // TODO Auto-generated method stub xvar = arg0.getX(); yvar = arg0.getY(); inst1.return_paint(xvar, yvar); } } class PaintClass22 extends JPanel{ private static int varx; private static int vary; public void return_paint(int input1, int input2){ varx = input1; vary = input2; repaint(varx,vary,10,10); } public void paintComponent(Graphics g){ super.paintComponents(g); g.setColor(Color.RED); g.fillRect(varx, vary, 10, 10); } }

  • Avoiding instanceof in Java

    - by Mark Lutton
    Having a chain of "instanceof" operations is considered a "code smell". The standard answer is "use polymorphism". How would I do it in this case? There are a number of subclasses of a base class; none of them are under my control. An analogous situation would be with the Java classes Integer, Double, BigDecimal etc. if (obj instanceof Integer) {NumberStuff.handle((Integer)obj);} else if (obj instanceof BigDecimal) {BigDecimalStuff.handle((BigDecimal)obj);} else if (obj instanceof Double) {DoubleStuff.handle((Double)obj);} I do have control over NumberStuff and so on. I don't want to use many lines of code where a few lines would do. (Sometimes I make a HashMap mapping Integer.class to an instance of IntegerStuff, BigDecimal.class to an instance of BigDecimalStuff etc. But today I want something simpler.) I'd like something as simple as this: public static handle(Integer num) { ... } public static handle(BigDecimal num) { ... } But Java just doesn't work that way. I'd like to use static methods when formatting. The things I'm formatting are composite, where a Thing1 can contain an array Thing2s and a Thing2 can contain an array of Thing1s. I had a problem when I implemented my formatters like this: class Thing1Formatter { private static Thing2Formatter thing2Formatter = new Thing2Formatter(); public format(Thing thing) { thing2Formatter.format(thing.innerThing2); } } class Thing2Formatter { private static Thing1Formatter thing1Formatter = new Thing1Formatter(); public format(Thing2 thing) { thing1Formatter.format(thing.innerThing1); } } Yes, I know the HashMap and a bit more code can fix that too. But the "instanceof" seems so readable and maintainable by comparison. Is there anything simple but not smelly?
