  • Kohana v2 - problem with routes

    - by yoda
    Hi, I'm attempting to set some custom routes in Kohana v2. What I'm looking for is some method that allow the system to : follow a pre-defined name to it's related root; redirect the non-matched url's into another controller; To give you a more clear view over the problem, I want the first url parameter to be associated to certain pages (contacts, home, services, about us, etc), and those urls who doesn't match the previous pages would be routed into a controller called products, in order to determine if the first url parameter regards a product name. Here's a sample of what I have : $config['_default'] = 'home'; $config['([a-zA-Z]+)'] = 'products/showcat/$1'; What am I missing here? Thanks in advance!

  • Sending url params and POST body to a MVC 2 Controller

    - by Luiggi
    Hi, I'm having some issues trying to make a HTTP PUT (or POST) using WebClient against a MVC 2 controller. The exception is: The parameters dictionary contains a null entry for parameter 'total' of non-nullable type 'System.Int32' for method 'System.Web.Mvc.ActionResult Company(System.Guid, Int32, Int32, System.String)' The controller action is: [HttpPut] public ActionResult Company(Guid uid, int id, int total, string url) The route is: routes.MapRoute( "CompanySet", "job/active/{uid}/company/{id}", new { controller = "Job", action = "Company" } ); As you may see, what I want is to send the 'uid' and 'id' parameters via url, but the 'total' and 'url' parameters as part of the PUT or POST body. I've also tried to merge the latter parameters into a class (i.e., CompanySetMessage), doing it no longer raises an exception but I dont receive the values on the server side. Any ideas? Thank you!

  • In .NET which loop runs faster for or foreach

    - by Binoj Antony
    In c#/VB.NET/.NET which loop runs faster for or foreach? Ever since I read that for loop works faster than foreach a long time ago I assumed it stood true for all collections, generic collection all arrays etc. I scoured google and found few articles but most of them are inconclusive (read comments on the articles) and open ended. What would be ideal is to have each scenarios listed and the best solution for the same e.g: (just example of how it should be) for iterating an array of 1000+ strings - for is better than foreach for iterating over IList (non generic) strings - foreach is better than for Few references found on the web for the same: Original grand old article by Emmanuel Schanzer CodeProject FOREACH Vs. FOR Blog - To foreach or not to foreach that is the question asp.net forum - NET 1.1 C# for vs foreach [Edit] Apart from the readability aspect of it I am really interested in facts and figures, there are applications where the last mile of performance optimization squeezed do matter.

  • Ruby/RoR: calling original method via super()?

    - by fearless_fool
    In a RoR app, I want to specialize ActiveRecord's update_attributes() method in one of my models, extracting some of the attributes for special handling and passing the rest of them to the original update_attributes() method. The details: class Premise < ActiveRecord::Base ... def update_attributes(attrs) attrs.each_pair do |key, val| unless has_attribute?(key) do_special_processing(key, val) attrs.delete(key) end end # use original update_attributes() to process non-special pairs super.update_attributes(attrs) end ... end The call to super.update_attributes(attr) raises an error: undefined method `update_attributes' for true:TrueClass ... which makes me suspect I really don't understand the super keyword in Ruby. What am I missing? Specifically, how do I call the original update_attributes() method?

  • Converting ObjC Blocks to C# Lambas

    - by Sam
    I need some help converting an Objective-C block to C#. Here is the source ObjC: NSDate* addYear = [_calendar dateByAddingComponents:((^{ NSDateComponents* components = [NSDateComponents new]; components.month = 12; return components; })()) toDate:now options:0]; Now I tried the following in C#: NSDate date = _calendar.DateByAddingComponents((() => { NSDateComponents components = new NSDateComponents(); components.Month = 12; return components; })(), now, NSCalendarOptions.None); To which I get the following compiler error: Expression denotes a 'anonymous method' where a 'method group' was expected. Removing the parentheses around the lambda yields Cannot convert 'lambda expression' to non-delegate type 'MonoTouch.Foundation.NSDateComponents'. What is the correct C# syntax? I need to retain the closures as there are a lot more in the code base that I am porting.

  • Debugging a Browser Redirect Loop

    - by just_wes
    Hi all, I am using CakePHP with the Auth and ACL components. My page loads fine for non-registered users, but if I try to log in as a registered user I get an infinite redirect loop in the browser. I am sure that this is some sort of permissions problem, but the problem exists even for users who have permissions for everything. The only way to prevent this behavior is to allow '*' in my AppController's beforeFilter method. What is the best way to debug this sort of problem? Thanks!

  • Android playing Video data from a custom network stream?

    - by Cinar
    Does Android MediaPlayer can only work with file sources? I would like play media (video) from a network stream, but the stream comes in a non-standard protocol, so I have to somehow feed Android MediaPlayer with the data only. Is there anyway to do that? I found a few web pages suggesting using a temporary file for the buffered media data etc. but I would like to minimize the I/O usage as much as I can, so I'm looking for a API only solution if there is any? how about JNI? but looks like the permissions going to be an issue with that also.

  • Is it a good idea to keep documentation in the VCS?

    - by Jj
    At work we just moved to Mercurial for our VCS from SVN. In SVN we used to have a "docs" folder next to "trunk", in "docs" we would keep all our file documentation, client files, diagrams, mockups, etc. (we use a wiki(Redmine) for internal documentation). Now in a DVCS enviroment we don't need a "trunk" folder, so we drop the code at the root of the repo, and now having a "docs" folder inside the repo feels weird being at the same level that the code. This has taken me to reconsider if it is a good idea to keep those files in the VCS, we have a "documents" section in Redmine, but I have never used it because it is a pain to have to download a file each time I want to open it and I can't access the file when I'm offline. What best practices have you guys found to manage these kind of non-code files?

  • App Engine - Objectify - Storing a byte[]

    - by Spines
    I'm using the Objectify library for interfacing with the app engine datastore. In my User class, I store the hashed password as a byte[]. When I put it in the datastore, it is correctly stored as a blob. When I try to load the User object back out I get this error: java.lang.IllegalStateException: Cannot load non-collection value '<Blob: 40 bytes>' into private byte[] How do I fix this? Do I have to change my User class to have the hashed password be of type ShortBlob?

  • How can unit testing make parameter validation redundant?

    - by Johann Gerell
    We have a convention to validate all parameters of constructors and public functions/methods. For mandatory parameters of reference type, we mainly check for non-null and that's the chief validation in constructors, where we set up mandatory dependencies of the type. The number one reason why we do this is to catch that error early and not get a null reference exception a few hours down the line without knowing where or when the faulty parameter was introduced. As we start transitioning to more and more TDD, some team members feel the validation is redundant. Uncle Bob, who is a vocal advocate of TDD, strongly advices against doing parameter validation. His main argument seems to be "I have a suite of unit tests that makes sure everything works". But I can for the life of it just not see in what way unit tests can prevent our developers from calling these methods with bad parameters in production code. Please, unit testers out there, if you could explain this to me in a rational way with concrete examples, I'd be more than happy to seize this parameter validation!

  • Why does Python's __import__ require fromlist?

    - by ieure
    In Python, if you want to programmatically import a module, you can do: module = __import__('module_name') If you want to import a submodule, you would think it would be a simple matter of: module = __import__('module_name.submodule') Of course, this doesn't work; you just get module_name again. You have to do: module = __import__('module_name.submodule', fromlist=['blah']) Why? The actual value of fromlist don't seem to matter at all, as long as it's non-empty. What is the point of requiring an argument, then ignoring its values? Most stuff in Python seems to be done for good reason, but for the life of me, I can't come up with any reasonable explanation for this behavior to exist.

  • What's the most straightforward way to typeset MLA-style college essays in LaTeX?

    - by bcat
    I've been using LaTeX for a little while now to typeset my algorithms homework, and I really like the quality of the output as well as the ease-of-use. I'd like to starting using LaTeX in other classes as well, but non–computer-science subjects have more stringent formatting requirements than I've come across in CS. Most classes that require essays want them to be formatted in MLA style, but I'm not sure what to best way to do that using LaTeX is. I've tried Googling "latex mla" and other similar things, but I've found many different MLA templates, and my LaTeX skills aren't good enough to determine which is the best. Is anyone else using LaTeX for "normal" essays, and, if so, how are you doing it?

  • How do I pass (by value) a struct in Objective-C?

    - by Striker
    This one has been driving me mad! I have a struct: typedef struct{ int a; }myStruct; Then I have: myStruct tempStruct; I am trying to pass the struct to a class method whose implementation is: - (void) myFunc:(struct myStruct)oneOfMyStructs{}; I call the method like so: [myClass myFunc:(struct myStruct)tempStruct]; The compiler complains about "Conversion to non-scalar type requested." All I want to do is pass a struct into a class method, but the syntax has me a bit confused. I'm new to Objective-C. Please let me know if you can see where I'm going wrong. I've not been able to pass by reference either, so if you could help me out with that, that would be great! Thanks!

  • Edit and create nodes in a view?

    - by tputkonen
    We are storing people's class attendance information to Drupal. We would like to show this in a grid/chart, where the first column of each row shows person's name, and rest of the columns (ca. 20) either a checkbox or "X" if the user attended a class, or otherwise an non-checked box or empty column: (dates here) Jack X XXX X X Jill XX XXX XX It should also be possible to edit the attendance information on the grid. Each attendance information is a node of its own. This functionality can probably mostly be achieved using views and editablefields, but there is one problem: if a person has not attended a specific class he/she will not have at all an attendace node for that day. What would be the easiest way to create an attendace node in those cases, so that it would be possible for the end user to edit the grid by just clicking on the checkbox or typing an 'X'?

  • asp.net mvc route clashing with physical path in IIS7

    - by Andrew Bullock
    I'm messing about with controller organisation and I've hit a problem. If I have the following physical structure /Home/HomeController.cs /Home/Index.aspx /Home/About.aspx and I request the URI: /Home/Index I get a 403 Directory Listing Denied :( (im using a custom IControllerFactory and IViewEngine to look in this non-default path) Why is this happening? (I know the 403 is because its hitting the /Home folder, but why is it hitting the folder?) Why doesn't the UrlRoutingModule rewrite the route and let the controller pick up the request? Application_BeginRequest fires, but then it seems to pass control back to IIS to try and serve from the filesystem. Is it the UrlRoutingModule that defaults to a physical path if it exists before rewriting? Is there a way to make this work? N.B. Please don't suggest relocating my controllers etc. I know this is an obvious option, but that isn't the question ;) Using IIS7 In Integrated Mode Thanks

  • Check if a class is subclass of another class in Java

    - by craesh
    Hi! I'm playing around with Java's reflection API and trying to handle some fields. Now I'm stuck with identifying the type of my fields. Strings are easy, just do myField.getType().equals(String.class). The same applies for other non-derived classes. But how do I check derived classes? E.g. LinkedList as subclass of List. I can't find any isSubclassOf(...) or extends(...) method. Do I need to walk through all getSuperClass() and find my supeclass by my own? Thanks! craesh

  • Access the internal phonebook

    - by L0rdAli3n
    For more than two days now, I'm trying to grab a list of all contacts, from the internal phonebook (no facebook-, gmail- or twittercontacts) with their family- and givenname. I managed to get a list with all contacts, socialcontacts included. So I looked at the account_type and saw that on my HTC Desire they were all "com.htc.android.pcsc" and I was like "Great, I just have to filter the whole list". But then all people with non-htc android cellphones would be unable to use my app, if I would hardcode this filter. Next idea was to let the user choose which account he wants to use, but unfortunately the "com.htc.android.pcsc" didn't appear in the list I got from the AccountManager?!? So my question is: Is there any standardized way to access the internal phonebook? I'm really stuck with that and any hint is highly appreciated!

  • SQLite problem with some parameterized queries

    - by Trevor Balcom
    I am having some trouble using SQLite and parameterized queries with a few tables. I have noticed some queries using the "SELECT * FROM Table WHERE row=?" are returning 1 row when there should be more rows returned. If I change the parameterized query to "SELECT * FROM Table WHERE row='row'" then the correct number of rows is returned. Does anyone know why sqlite3_step would return only 1 row when using a parameterized query vs. using the same query in a traditional non-parameterized way? I am using a very thin C++ wrapper around SQLite3. I suspect there could be a problem with the wrapper, but this problem only exists on a few tables. It makes me wonder if there is something wrong with the way those tables are setup. Any advice is appreciated.

  • Streaming multiple TObjects to a TMemoryStream

    - by Altar
    I need to store multiple objects (most of them are TObject/non persistent) to a TMemoryStream, save the stream to disk and load it back. The objects need to be streamed one after each other. Some kind of universal container. I started to make several functions that store stuff to stream - for example function StreamReadString(CONST MemStream: TMemoryStream): string; StreamWriteString(CONST MemStream: TMemoryStream; s: string); However, it seems that I need to rewrite a lot of code. One of the many examples is TStringList.LoadFromStream that will not work so it needs to be rewritten. This is because TStringList needs to be the last object in the stream (it reads from current position to the end of the stream). Anybody knows a library that provide basic functionality like this? I am using Delphi 7 so RTTI won't help too much.

  • PHP Change Array Over and Over

    - by Steven
    Hello, I have any array $num_list = array(42=>'0',44=>'0',46=>'0',48=>'0',50=>'0',52=>'0',54=>'0',56=>'0',58=>'0',60=>'0'); and I want to change specific values as I go through a loop while(list($pq, $oin) = mysql_fetch_row($result2)) { $num_list[$oin] = $pq; } So I want to change like 58 to 403 rather then 0. However I always end up getting just the last change and non of the earlier ones. So it always ends up being something like 0,0,0,0,0,0,0,0,0,403 rather then 14,19,0,24,603,249,0,0,0,403 How can I do this so it doesn't overwrite it? Thanks

  • Scalable (half-million files) version control system

    - by hashable
    We use SVN for our source-code revision control and are experimenting using it for non-source-code files. We are working with a large set (300-500k) of short (1-4kB) text files that will be updated on a regular basis and need to version control it. We tried using SVN in flat-file mode and it is struggling to handle the first commit (500k files checked in) taking about 36 hours. On a daily basis, we need the system to be able to handle 10k modified files per commit transaction in a short time (<5 min). My questions: Is SVN the right solution for my purpose. The initial speed seems too slow for practical use. If Yes, is there a particular svn server implementation that is fast? (We are currently using the gnu/linux default svn server and command line client.) If No, what are the best f/oss/commercial alternatives Thanks

  • What platforms have something other than 8-bit char?

    - by Craig McQueen
    Every now and then, someone on SO points out that char (aka 'byte') isn't necessarily 8 bits. It seems that 8-bit char is almost universal. I would have thought that for mainstream platforms, it is necessary to have an 8-bit char to ensure its viability in the marketplace. Both now and historically, what platforms use a char that is not 8 bits, and why would they differ from the "normal" 8 bits? When writing code, and thinking about cross-platform support (e.g. for general-use libraries), what sort of consideration is it worth giving to platforms with non-8-bit char? In the past I've come across some Analog Devices DSPs for which char is 16 bits. DSPs are a bit of a niche architecture I suppose. (Then again, at the time hand-coded assembler easily beat what the available C compilers could do, so I didn't really get much experience with C on that platform.)

  • The remote server returned an error: (407) Proxy Authentication Required

    - by chris
    I'm getting this error when I call a web service: "The remote server returned an error: (407) Proxy Authentication Required". I get the general idea and I can get the code to work by adding myProxy.Credentials= NetworkCredential("user", "password", "domain"); or by using DefaultCredentials in code. My problem is that the call to the web service works in production without this. It seems like there is a non code solution involving Machine.config, but what is it? At the moment I can't get to the production boxes machine.config file to see what that looks like. I tried updating my machine.config as follows, but I still get the 407 error.

  • DOM class injection in PHP

    - by Adam Kiss
    idea Via jQuery, I was able to mark all :first-child and :last-child elements in document (well, almost all :)) with class first which could I later style (i.e. first li in ul#navigation would be easily adressable as ul#navigation .first). I used following code: var $f = $('*:first-child') $f.addClass('first'); var $l = $('body *:last-child') $l.addClass('last'); question Now, my question is if it's possible to do the same via php, so non-JS users/gadgets could have the same effects and additional styling and also it would be less overkill on browser. So, is it possible to capture output, parse it as html and inject this class easily in php?
