  • doctrine2: many-to-one with non default referencedColumnName does not persist entity

    - by timaschew
    I'm using symfony 2.1.2 with FOSUserBundle. I extend the User from FOS and define a many-to-one (bidirectional) association to a Customer entity. I don't want to use primary key for the association (referencedColumnName). I will use another integer uniqe column: customer_no use FOS\UserBundle\Entity\User as BaseUser; /** * @ORM\Entity * @ORM\Table(name="t_myuser") */ class MyUser extends BaseUser { /** * @ORM\ManyToOne(targetEntity="Customer", inversedBy="user") * @ORM\JoinColumn(name="customer_no", referencedColumnName="customer_no", nullable=false) */ $public $customer; } /** * @ORM\Entity * @ORM\Table(name="t_customer") */ class Customer extends BaseEntity // provides an id (pk) { /** * @ORM\Column(type="integer", unique=true, nullable=false) */ public $customer_no; /** * @ORM\OneToMany(targetEntity="MyUser", mappedBy="customer") */ public $user; } When I try to persist (via a form) a new MyUser entity with an (already in db existing and) loaded Customer entity from db, I get this error: Notice: Undefined index: customer_no in ...\vendor\doctrine\orm\lib\Doctrine\ORM\Persisters\BasicEntityPersister.php line 608 The schema on the db is all right. //update: I fix the inversedBy and mappedBy stuff, but this is not the problem.

  • Looking for the most painless non-RDBMS storage method in C#

    - by NateD
    I'm writing a simple program that will run entirely client-side. (Desktop programming? do people still do that?) and I need a simple way to store trivial amounts of data in a structured form, but really don't see any need to use a database system. What's more, some of the data needs to be serialized and passed around to different users, like some kind of "file" or perhaps a "document". (has anyone ever done that before?) So, I've looked at using .Net DataSets, LINQ, direct XML manipulation, and they all seem like they would get the job done, but I would like to know before I dive into any of them if there's one method that is generally regarded as easier to code than others. As I said, the amount of data to be stored is trivial, even if one hundred people all used the same machine we're not talking about more than 10 MB, so performance is not as large a concern as is codeability/maintainability. Thank you all in advance!

  • Flexible CMS for non-programmers

    - by Bunkerbewohner
    Hello! I'm looking for a content management system that allows creating single pages out of predefined blocks flexibly. For example I have a "product" block that is used to show producs on a page and it may appear numerous times on one page with different contents. But I also might wanna use it on different pages. Also I have simply generic blocks like multiple column text blocks (1 col, 2 col etc.) where I just want to insert this kind of structure into the page and enter any text. So I'm looking for a cms with someething like a building block / module concept for contents. I'm already searching the web but there are so many CMSs that I can't look into every one. So if anyone knows a solution that might be right for me, please tell me! Technology-wise it just has to run on Linux. If it's OpenSource / free that's great, but I might also pay for it, if it offers the features I want. Thanks for any hints in advance!

  • Minimum power requirement for VGA vs. its working

    - by Shiki
    Got a new XFX GTX260^2 video card. The only problem is the "Minimum power" is 500W on the box. I've got a Chieftec 450AA PSU with just a minimal number of attached stuff (1hdd, WD green; 6gb (4module) ram; dvd writer). Bought a cable for the 6pin power input on the card. Got picture, works in every aspect. Still. Should I get a new PSU (like a Corsair or Antec 600W)? Will the card perform slower with this PSU? (Yeah the last part is a particular question but in I'm also asking in generic. I was wondering about this so many times and I hope we'll put and end for this question for once and for all.)

  • RIA Services for transmitting non DB object-graph

    - by Mike Gates
    I have been getting into RIA services because I thought it would simplify dealing with the services layer of web applications I wish to build. I see lots of examples out there showing how to create DomainService classes which expose and consume entities that have some kind of relational database backing, and therefore have foreign-key relationships. However, I would like to know how to expose and consume normal object graphs...objects that contain references to eachother but don't have foreign keys. For example, say I want a service operation called "GetFolderInformation(string pathToFolder)". I want this to return a custom object called "FolderInformation" structured with: - string Name - IEnumerable<FileInformation> Files I cannot get this to work because it seems that RIA wants to deal with entities that have foreign key relationships. Why? Why can't the serializer just see my object references and recreate that in the proxy on the other side? Data exists behind service layers that doesn't necessarily have foreign key relationships...like folder/file for example. EDIT: I realized I hadn't asked my question! My question is, is there a way to do what I am trying to do?

  • How to inherit from a non-prototype object

    - by Andres Jaan Tack
    The node-binary binary parser builds its object with the following pattern: exports.parse = function parse (buffer) { var self = {...} self.tap = function (cb) {...}; self.into = function (key, cb) {...}; ... return self; }; How do I inherit my own, enlightened parser from this? Is this pattern designed intentionally to make inheritance awkward? My only successful attempt thus far at inheriting all the methods of binary.parse(<something>) is to use _.extend as: var clever_parser = function(buffer) { if (this instanceof clever_parser) { this.parser = binary.parse(buffer); // I guess this is super.constructor(...) _.extend(this.parser, this); // Really? return this.parser; } else { return new clever_parser(buffer); } } This has failed my smell test, and that of others. Is there anything about this that makes in tangerous?

  • socket.shutdown vs socket.close

    - by Jason Baker
    I recently saw a bit of code that looked like this (with sock being a socket object of course): sock.shutdown(socket.SHUT_RDWR) sock.close() What exactly is the purpose of calling shutdown on the socket and then closing it? If it makes a difference, this socket is being used for non-blocking IO.

  • Custom View - Avoid redrawing when non-interactive

    - by MasterGaurav
    I have a complex custom view - photo collage. What is observed is whenever any UI interaction happens, the view is redrawn. How can I avoid complete redrawing (for example, use a cached UI) of the view specially when I click the "back" button to go back to previous activity because that also causes redrawing of the view. While exploring the API and web, I found a method - getDrawingCache() - but don't know how to use it effectively. How do I use it effectively? I've had other issues with Custom Views that I outline here.

  • Making a non-trivial Image and Video Gallery with a really nice interface

    - by Cawas
    Short part: I'm starting to build an Image and Video Gallery for our intranet. It's pretty much like an image gallery with video thumbnails that play on click. It's just good to keep that in mind because caching and streaming happen in very different ways there. It will serve to browse our reference database, which will also contain searching, tagging and voting. There are 3 features that I need to begin with: Quick preview of thumbnails from each Gallery Fast zoom in / out Animated scrolling Now to the long part, since I can't seem to reduce this: I hope this question belongs here. Maybe people can read this through and identify with it, specially since I expect answers to be pretty specific. The first plan was getting Apple's mobile me gallery as base, because it just so happens to have all those 3 features. If you've never seem it, you should check it out. Move the mouse over each collection and you'll get a nice preview "per pixel". Carousel got a really good scrolling, not just because of the pretty effect. I like it much more than cooliris, but it would be nice to have it in several rows, maybe without the magnifying effect... Then it could be all in the same place with the zoom. The more the features blend-in together, the better. Zooming out with the mouse, scrolling by dragging, once the zoom is really out it becomes a browsing through galleries, with the quick-show preview of each, all properly cached and fast. That'd be perfect. A very compelling interface will be important in this project. Well, my point here is just describing what I need and hope to hear from people with more experience in all that stuff of what's already done and what I'd have to do myself. And how (i.e. which framework to use) to do it. To begin with, I've found a gallery demo and its source code (I think it was from here, but the link seems broken now). I guess it was made in SproutCore, which is what mobileme was based upon. Definitely with JQuery (which already seems a little slow). But I'm still missing two features there: the carousel and the fast zoom (it's just not as slow as the zoom in this demo with cappuccino). Then I've found a supposedly better one with a pretty good and similar zoom, that I'm not sure if it's using any framework and is already in php. Right now it'd be better having just the HTML, no server-side, since I'm building interface first. So, can anyone point directions? There are way too many options! Should I look for another solution closer to what I need, or try and tweak this one? I'm not familiar with any framework at all. Sorry for bringing this question that I will have to answer myself anyway sooner or later and sorry that I couldn't make this smaller. Thanks.

  • Sql Server differential backup : Simple vs Full recovery model

    - by MaxiWheat
    I need to better understand the backup process under SQL Server 2008. Since drive space is a kind of matter for us and we want to have a better disaster recovery solution, I decided that we will implement differential backups throughout the day (every hour). Am I right to think that if I keep the recovery model of my databases to Simple, the differential backup will be almost the same size as Full Backup (too big to make one every hour) ? I already tried to switch to Full recovery and it seemed to have fixed the issue (differential backups were way smaller). I heard that the recovery model must be set to Full to use Log backups (to the minute recovery etc., but we don't need that) but never about differential backups. So, is the recovery model really having an impact on differential backups or am I missing something ? Thank you

  • Annex-A vs Annex-B ADSL splitters

    - by Odys
    While trying to improve our Adsl connection, I found that we use a splitter that is from an unknown ventor and have no clue whether is for AnnexA (PSTN) or AnnexB (ISDN) line. Is it possible that somebody used the wrong splitter and just because it connected nobody ever cared? We have an ISDN line but the splitter used is blank. I am not really sure if it is AnnexB. Would it be possible to use an AnnexA filter over an ISDN line (even with that much signal loss)? (I am posting here because this is about our connection to the rack, I'm not sure if there is a more proper SExchange site)

  • undefined references

    - by Brandon
    Hello, I'm trying to compile some fortran code and I'm running into some confusing linking errors. I have some code that I compile and place into a static library: >gfortran -c -I../../inc -o bdout.o bdout.F >ar rv libgeo.a bdout.o I then try to compile against that library with some simple test code and get the following: >gfortran -o mytest -L -lgeo mytest.F /tmp/cc4uvcsj.o: In function `MAIN__': mytest.F:(.text+0xb0): undefined reference to `ncwrite1_' collect2: ld returned 1 exit status It's not in the object naming because everything looks fine: >nm -u libgeo.a bdout.o: U _gfortran_exit_i4 U _gfortran_st_write U _gfortran_st_write_done U _gfortran_transfer_character U _gfortran_transfer_integer U ncobjcl_ U ncobjwrp_ U ncopencr_ U ncopenshcr_ U ncopenwr_ U ncwrite1_ U ncwrite2_ U ncwrite3_ U ncwrite4_ U ncwritev_ I can check the original object file too: >nm -u bdout.o U _gfortran_exit_i4 U _gfortran_st_write U _gfortran_st_write_done U _gfortran_transfer_character U _gfortran_transfer_integer U ncobjcl_ U ncobjwrp_ U ncopencr_ U ncopenshcr_ U ncopenwr_ U ncwrite1_ U ncwrite2_ U ncwrite3_ U ncwrite4_ U ncwritev_ The test code simply contains a single call to a function defined in bdout.o: program hello print *,"Hello World!" call ncwrite1( istat, f, ix2, ix3, ix4, ix5, ih ) end program hello I can't figure out what the problem is. Does anyone have any suggestions? Maybe even just a way to track the problem down? Cheers.

  • what dataprovider in flex (aside from ArrayCollection) will work for single, non-repeating XML nodes

    - by Rees
    hello, i asked this question before but haven't been able to get an answer.. i get the following error when i retrieve an XML that only has 1 node (no repeating nodes) from a PHP page and i try to store in an ArrayCollection. -When I have MORE than 1 "name" nodes...i do NOT get an error. TypeError: Error #1034: Type Coercion failed: cannot convert "XXXXXX" to mx.collections.ArrayCollection. this error occurs as the line of code: myList= e.result.list.name; I'm using this ArrayCollection as a dataprovider for a Component -is there an alternative I can use that will take BOTH single and repeating nodes as well as work as a dataprovider? Thanks in advance! code: [Bindable] private var myList:ArrayCollection= new ArrayCollection(); private function getList(e:Event):void{ var getStudyLoungesService:HTTPService = new HTTPService(); getStuffService.url = "website.com/asdf.php"; getStuffService.addEventListener(ResultEvent.RESULT, onGetList); getStuffService.send(); } private function onGetList(e:ResultEvent):void{ myList= e.result.list.name; }

  • PS/2 vs USB keyboards: performance and energy consumption

    - by Mister Smith
    As far as I know, PS/2 keyboards are interrupt driven, while USB are polled. Typically a PS/2 keyboard was assigned IRQ_1 on Windows. I'm no hardware expert, but at a first glance seems like the PS/2 keyboards are more efficient. So here are my questions: On modern day computers, are PS/2 keyboard better (or faster), and if so, would it be noticeable at all? (e.g.: in gaming) Since they don't need polling, do PS/2 keyboards save energy compared to USB? (notice I'm not talking only about the peripheral here, but about the overall computer energy consumption). In case PS/2 had any advantage over USB, would adding a PS/2 adapter to my USB keyboard make the device as good as an actual PS/2 keyboard? Conversely, would adding a USB adapter to a PS/2 make it as bad as a USB KB? Thanks in advance.

  • Simple non-network concurrency with Twisted

    - by Rince
    Dear pythoners, I have a problem with using Twisted for simple concurrency in python. The problem is - I don't know how to do it and all online resources are about Twisted networking abilities. So I am turning to SO-gurus for some guidance. Python 2.5 is used. Simplified version of my problem runs as follows: A bunch of scientific data A function that munches on the data and creates output ??? < here enters concurrency, it takes chunks of data from 1 and feeds it to 2 Output from 3 is joined and stored My guess is that Twisted reactor can do the number three job. But how? Thanks a lot for any help and suggestions.

  • Mocking a non-settable child property with Rhino Mocks

    - by Marcus
    I currently have interfaces much like the following: interface IService { void Start(); IHandler ServiceHandler { get; } } interface IHandler { event EventHandler OnMessageReceived; } Using Rhino Mocks, it's easy enough to mock IService, but it doesn't assign any IHandler instance to the ServiceHandler property. Therefore when my method under test adds an event handler to _mockedService.ServiceHandler.OnMessageReceived, I get an 'Object reference not set' error. How can I ensure that ServiceHandler is assigned a value in the mocked IService instance? This is likely Rhino Mocks 101, but I'm just getting up to speed on it...

  • CCATS needed for non-export iPhone app?

    - by Steve
    I'm getting ready to finally deploy my first iPhone app. The app uses SSL to connect to a REST web service. While reading the docs on deploying the app to the app store, I came across some drivel regarding having to go through a 30 - 60 day government vetting process just to ship an app that simply connects to an HTTPS server. My question is, since this is an export requirement, do apps that are only distributed in the US face this same restriction? Thanks

  • How can I fix this clang warning: "Object with +0 retain counts returned to caller where +1 (owning)

    - by mipadi
    I have a piece of Objective-C code that looks like the following: - (NSString *)copyData:(NSData *)data { NSString *path = [[[self outputDirectory] stringByAppendingPathComponent:@"archive"] stringByAppendingPathExtension:@"zip"]; NSLog(@"Copying data to %@", path); [data writeToFile:path atomically:NO]; return path; } The code is called from an initializer that looks like this: - (id)initWithData:(NSData *)data { if ((self = [super init]) != nil) { NSString *path = [self copyData:data]; // Line 41 (referenced in warning, shown below) return [self initWithContentsOfFile:path]; } return self; } When running the clang static analyzer, I get the following warnings for the path variable: Potential leak of an object allocated on line 41 and stored into 'path' Object with +0 retain counts returned to caller where +1 (owning) retain count is expected I'm confused. My understanding is that stringByAppendingPathComponent should not return an autoreleased string, so it should have a net retain count of 0. (Obviously I don't want to retain it.) I've tried altering copyData: to return the following, but it didn't get rid of the warning: return [[path retain] autorelease]; So what's the deal with this warning?

  • Streaming a non-PCM WAV file to a SilverLight application

    - by Satumba
    Hi, I would like to allow users to play recorded WAV files that stored on a server back to a Silverlight application as a client to play them. I saw that there is a way to play a WAV file on Silverlight (here), but when i tried to impliment it, i got an error playing the file because it is not in PCM format but encoded. The files that i'm trying to play are encoded with a special encoder, so i thought that the only way is to decode the WAV file on the server and stream it back to the client. The limitation is that the decode process should occur in real time because it is not reasonable to convert all the WAV files that exists. Is it possible to do it? Which streamer can i use? (Windows Media Service can help here?) Does somebody has any experience with such a scenario? Appreciate your help.

  • Dynamically assigning properties on a non data bound ASP.NET control

    - by thinknow
    For example, let's say I have a HyperLink: <asp:HyperLink runat="server" Text="Foo" NavigateUrl="foo.aspx" /> How can I set the NavigateUrl on the server side, without having to go the code-behind? This doesn't work of course: <asp:HyperLink runat="server" Text="Foo" NavigateUrl="<%= urlString %>" /> (where urlString might be a string I created earlier in the page) And this doesn't work because the HyperLink is not within a data bound control: <asp:HyperLink runat="server" Text="Foo" NavigateUrl='<%# urlString %>' /> I guess I could just use a standard anchor element: <a href="<%= urlString %>">Foo</a> But I'd rather not mix up HTML and ASP.NET controls, and it would be handy to be able to do this for other controls. Surely there must be a way?

  • Stability, x86 Vs Sparc

    - by Jason T
    Our project are plan to migrate from Sparc to x86, and our HA requirement is 99.99%, previous on Sparc, we assume the hardware stability would like, hardware failure every 4 month or even one year, and also we have test data for our application, then we have requirement for each unplanned recovery (fail over) to achieve 99.99% (52.6 minutes unplanned downtime per year). But since we are going to use Intel x86, it seems the hardware stability is not so good as Sparc, but we don't have the detail data. So compare with Sparc, how about the stability of the Intel x86, should we assume we have more unplanned downtime? If so, how many, double? Where I can find some more detail of this two type of hardware?

  • Deleting a non-owned dynamic array through a pointer

    - by ayanzo
    Hello all, I'm relatively novice when it comes to C++ as I was weened on Java for much of my undergraduate curriculum (tis a shame). Memory management has been a hassle, but I've purchased a number books on ansi C and C++. I've poked around the related questions, but couldn't find one that matched this particular criteria. Maybe it's so obvious nobody mentions it? This question has been bugging me, but I feel as if there's a conceptual point i'm not utilizing. Suppose: char original[56]; cstr[0] = 'a'; cstr[1] = 'b'; cstr[2] = 'c'; cstr[3] = 'd'; cstr[4] = 'e'; cstr[5] = '\0'; char *shaved = shavecstr(cstr); delete[] cstrn; where char* shavecstr(char* cstr) { size_t len = strlen(cstr); char* ncstr = new char[len]; strcpy(ncstr,cstr); return ncstr; } In that the whole point is to have 'original' be a buffer that fills with characters and routinely has its copy shaved and used elsewhere. To prevent leaks, I want to free up the memory held by 'shaved' to be used again after it passes through some arguments. There is probably a good reason for why this is restricted, but there should be some way to free the memory as by this configuration, there is no way to access the original owner (pointer) of the data.
