  • Framework Similar to Pylons for Ruby

    - by Travis
    I've been using Python for most of my web projects lately, and have come to really love the Pylons MVC framework. I like the incredible transparency (lack of magic), the built-in components they selected (sqlalchemy, formencode, routes), and the ability to easily change things up (use a different ORM or templating engine). Moving forward, due to constraints at my company, I'm going to be trying out Ruby rather than Python. I'm wondering if people with experience in both have any recommendations for a Ruby framework that is comparable to Pylons. Python is to Django as Ruby is to Rails Python is to Pylons as Ruby is to ?

  • VB.net 'cross-referencing' tables.

    - by Lee
    Hello, I have a DataGridView that is being filled with data from a table. Inside this table is a column called 'group' that has the ID of an individual group in another table. What I would like to do, is when the DataGridView is filled, instead of showing the ID contained in 'group', I'd like it to display the name of the group. Is there some type of VB.net 'magic' that can do this, or do I need to cross-reference the data myself? Here is a breakdown of what the 2 tables look like: table1 id group (this holds the value of column id in table 2) weight last_update table2 id description (this is what I would like to be displayed in the DGV.) take care, lee BTW - I am using Visual Studios Express.

  • Controller getting NULL value?

    - by RSolberg
    I'm trying to make a call to a controller via jQuery $.post, but the parameter for my controller method keeps getting a NULL value despite it appearing to be setup similar to other controller methods. CONTROLLER [AcceptVerbs(HttpVerbs.Post)] public ActionResult SearchWeatherLocations(string searchFor) { //Do Some Magic } GLOBAL.ASAX routes.MapRoute("SearchWeatherLocations", "Home/SearchWeatherLocations/{searchFor}", new { controller = "Home", action = "SearchWeatherLocations" }); jQuery Call From View <script type="text/javascript" language="javascript"> $(document).ready(function () { GetWeatherLocations("seat"); }); function GetWeatherLocations(sSearchFor) { var divToBeWorkedOn = '#locations'; var webMethod = '<%= Url.Action("SearchWeatherLocations", "Home") %>/'; var url = webMethod + sSearchFor; $.post(url, function (data) { $('#locations').children().remove(); for (var count in data) { $('#locations').append("<li>" + data[count].LocationName + "&nbsp;(" + data[count].LocationCode + ")</li>"); } }); } </script>

  • Can't get data with spaces into the database from Ajax POST request

    - by J Jones
    I have a real simple form with a textbox and a button, and my goal is to have an asynchronous request (jQuery: $.ajax) send the text to the server (PHP/mysql a la Joomla) so that it can be added to a database table. Here's the javascript that is sending the data from the client: var value= $('#myvalue').val(); $.ajax( { type: "POST", url: "/administrator/index.php", data: { option: "com_mycomponent", task: "enterValue", thevalue: value, format: "raw"}, dataType: "text", success: reportSavedValue } ); The problem arises when the user enters text with a space in it. The $_POST variable that I receive has all the spaces stripped out, so that if the user enters "This string has spaces", the server gets the value "Thisstringhasspaces". I have been googling around, and have found lots of references that I need to use encodeURIComponent. So I have tried it, but now the value that I get from $_POST is "This20string20has20spaces". So it appears to be encoding it the way I would expect, only to have the percent signs stripped instead of the spaces, and leaving the hex numbers. I'm really confused. It seems that this sort of question is asked and answered everywhere on the web, and everywhere encodeURIComponent is hailed as the silver bullet. But apparently I'm fighting a different breed of lycanthrope. Does anyone have any suggestions?

  • Type-safe, generic, empty Collections with static generics

    - by Droo
    I return empty collections vs. null whenever possible. I switch between two methods for doing so using java.util.Collections: return Collections.EMPTY_LIST; return Collections.emptyList(); where emptyList() is supposed to be type-safe. But I recently discovered: return Collections.<ComplexObject> emptyList(); return Collections.<ComplexObject> singletonList(new ComplexObject()); etc. I see this method in Eclipse Package Explorer: <clinit> () : void but I don't see how this is done in the source code (1.5). How is this magic tomfoolerie happening!!

  • Start exe even with missing dependency dlls?

    - by k3b
    In Dotnet2.0 and later a program refuses to start if one of its dependent (static referenced) dlls are missing. With Dotnet1.1 and 1.0 the program started but crashed later when trying to use functionality of the missing assembly. I wonder if there is something like a compiler switch , configuration option or a dotnet [attribute] to allow me to start the app when certain dlls are missing. Is it possible without moidfying the sourcecode (execpt by applying some Attriutes)? I don't want to manualy load assemblies by programcode or use IOC-Framworks. Update: With "static referenced dlls" i mean the opposite of dynamicly loading a dll in my own programcode using reflection and Assembly.Loadxxxx(). Update 2010-12-25: This scenario happens for example if you want to use Log4net with Dotnet4 clientprofile together with a WinForms-Aplication: Log4net requires System.Web.dll that is not in Dotnet4-Clientprofile. You must install dotnet4-web-support to use the winforms-aplication that is compiled against log4net unless there is some magic Compiler-switch/Attribute/Configuration that i am still looking for.

  • Migrating to CF9: trouble getting JRun working with SSL

    - by DaveBurns
    I have a client on MX7 who wants to migrate to CF9. I have a dev environment for them on my WinXP machine where I've configured MX7 to run with JRun's built-in web server. I've had that working for a long time with both regular and SSL connections. I installed CF9 yesterday side-by-side with the existing MX7 install to start testing. The install was smooth and detected MX7, adjusted CF9's port numbers for no conflict, etc. Testing started well: MX7 over regular and SSL still worked and CF9 worked over regular HTTP. But I can't get CF9 to work with SSL. I installed a new certificate with keytool, FireFox (v3.6) complained about it being unsigned, I added it to the exception list, and now I get this: Secure Connection Failed An error occurred during a connection to localhost:9101. Peer reports it experienced an internal error. (Error code: ssl_error_internal_error_alert) I've been Googling that in all variations but can't find much help to get past this. I don't see any info in any log files either. FWIW, here's my SSL config from SERVER-INF/jrun.xml: <service class="jrun.servlet.http.SSLService" name="SSLService"> <attribute name="enabled">true</attribute>` <attribute name="interface">*</attribute> <attribute name="port">9101</attribute> <attribute name="keyStore">{jrun.rootdir}/lib/mykey</attribute> <attribute name="keyStorePassword">*deleted*</attribute> <attribute name="trustStore">{jrun.rootdir}/lib/trustStore</attribute> <attribute name="socketFactoryName">jrun.servlet.http.JRunSSLServerSocketFactory</attribute> <attribute name="deactivated">false</attribute> <attribute name="bindAddress">*</attribute> <attribute name="clientAuth">false</attribute> </service> Anyone here know of any issues re setting up SSL and CF9? Anyone had success with it? Dave

  • What are the best options for a root filesystem hosted on SSD under Linux

    - by stsquad
    I'm working on an embedded system which is going to be booting and hosting it's rootfs on an SSD disk. We are currently looking at using Intel X-18M SSDs. The file system structure will have a fairly static /usr section (modulo software upgrades) and an active /var and /var/log for maintaining state and logging. Given the wear-levelling done by the underlying flash does having separate partitions help or hinder? As modern SSDs appear as straight block devices and hide their mapping magic behind their firmware is there any point trying to optimise the choice of file-system that sits on-top of the SSD? Finally does enable SMART monitoring make any sense in this context or are their SSD specific ways of determining the underlying health of the storage hardware?

  • Is it possible to use objects as function paremeters in EL with JBoss EL resolver?

    - by calavera.info
    There is this sentence in JBoss EL resolver online documentation: It's important to fully understand how this extension to EL works. When the page is rendered, the parameter names are stored (for example, hotel.id and user.username), and evaluated (as value expressions) when the page is submitted. You can't pass objects as parameters! But I had used objects as function parameters in my project before I accidentally read this hint and it worked! How is it possible? I'm afraid of that there is some magic now...

  • T4MVC calling controller methods multiple times?

    - by Maslow
    I suspected there was some hidden magic somewhere that stopped what looks like actual method calls all over the place in T4MVC. Then I had a view fail to compile, and the stackTrace went into my actual method, not the generated code in T4MVC. <%=Ajax.ActionLink("Apply", "Apply", new RouteValueDictionary() { { "shortName", item.Shortname } }, new AjaxOptions() { UpdateTargetId = "masterstatus" })%> <%=Html.ActionLink("Apply",MVC.Alliance.Apply(item.Shortname),new AjaxOptions() { UpdateTargetId = "masterstatus" }) %> The second method threw an exception on compile because the method Apply in my controller has an [Authorize] attribute so that if someone that isn't logged on clicks this, they get redirected to login, then right back to this page. There they can click on apply again, this time being logged in. And yes I realize one is Ajax.ActionLink while the other is Html.ActionLink I did try them both with the T4MVC version. Is this a fluke or is it actually calling into the real methods and running my database calling code just to generate the views?

  • Why LINQ will work this way?

    - by Benny
    public static ArrayList GetStudentAsArrayList() { ArrayList students = new ArrayList { new Student() { RollNumber = 1,Name ="Alex " , Section = 1 ,HostelNumber=1 }, new Student() { RollNumber = 2,Name ="Jonty " , Section = 2 ,HostelNumber=2 }, }; return students; } this doesn't compile: ArrayList is not IEnumerable ArrayList lstStudents = GetStudentAsArrayList(); var res = from r in lstStudents select r; but this will compile: ArrayList lstStudents = GetStudentAsArrayList(); var res = from Student r in lstStudents select r; Can anybody explain? what's the magic here?

  • Is there a certain IIS configuration required to allow a functioning .Net 4.0 ASP.Net MVC 2 Azure ap

    - by erg39
    I just installed the Azure 1.2 tools update and would like to get to work on an Azure project running locally using ASP.Net MVC and .Net 4, but I cannot get MVC pages to load. If I just create a new Azure project in VS 2010, add a ASP.Net MVC web role, and run the application, pages never load. It appears that routing is somehow at fault as controller actions never get called, but if I add other pages to the project (like .htm or .aspx) they will load in the browser. It all works fine with a new project using .Net 3.5, MVC 2 project in the Azure development environment; it all works fine with .Net 4.0 MVC 2 project that is not running in Azure; only the combination does not work. Environment is Win 7 x64 (IIS 7.5), VS 2010, Azure tools 1.2 Is there some magic IIS setting I need to change or something? Any ideas?

  • How does refer(r)er work technically?

    - by NoozNooz42
    I don't understand: how are webserver and trackers like Google Analytics able to track referrals? Is it part of HTTP? Is it some (un)specified behavior of the browsers? Apparently every time you click on a link on a web page, the original web page is passed along the request. What is the exact mechanism behind that? Is it specified by some spec? I've read a few docs and I've played with my own Tomcat server and my own Google Analytics account, but I don't understand how the "magic" happens. Bonus (totally related) question: if, on my own website (served by Tomcat), I put a link to another site, does the other site see my website as the "referrer" without me doing anything special in Tomcat?

  • Detecting that the stack is full in C/C++

    - by Martin Kristiansen
    When writing C++ code I've learned that using the stack to store memory is a good idea. But recently I ran into a problem: I had an experiment that had code that looked like this: void fun(unsigned int N) { float data_1[N*N]; float data_2[N*N]; /* Do magic */ } The code exploted with a seqmentation fault at random, and I had no idea why. It turned out that problem was that I was trying to store things that were to big on my stack, is there a way of detecting this? Or at least detecting that it has gone wrong?

  • Can't get custom error rendering to work in symfony 1.4

    - by hongkildong
    I'm tring to customize error rendering in my form according to this example. Here is my code: if ($this['message']->hasError()) { $error_msg = '<ul>'; foreach ($this['message']->getError() as $error) $error_msg .= "<li>$error</li>"; $error_msg .= '</ul>'; } return $error_msg; but when $this['message'] has error this code returns '<ul></ul>' so it seems foreach ($this['message']->getError() as $error) causes no iterations $this['message']->getError() returns sfValidatorError object - maybe something changed in symfony 1.4 and it isn't iterable anymore... At first I thought that all magic in that example happened because of object being placed in $error by iteration implements __toString() but it seems no iterations happens at all...

  • python xml.dom.minidom.Attr question

    - by rudy
    Getting attributes using minidom in Python, one uses the "attributes" property. e.g. node.attributes["id"].value So if I have <a id="foo"></a>, that should give me "foo". node.attributes["id"] does not return the value of the named attribute, but an xml.dom.minidom.Attr instance. But looking at the help for Attr, by doing help('xml.dom.minidom.Attr'), nowhere is this magic "value" property mentioned. I like to learn APIs by looking at the type hierarchy, instance methods etc. Where did this "value" property come from?? Why is it not listed in the Attr class' page? The only data descriptors mentioned are isId, localName and schemaType. Its also not inherited from any superclasses. Since I'm new to Python, would some of the Python gurus enlighten?

  • Dependency Injection with @Inject in Weld (JSR-299 RI). How is the corresponding @Produces found?

    - by Thorbjørn Ravn Andersen
    I have played with the JSR-299 Reference Implementation "Weld" with the purpose of using it in a stand-alone application, and I have had a look at the documentation, and marveled at the magic. My question is how the producer of a given object to be @Inject'ed is found? Either the java compiler produces hints for annotations which is easily found by the classloader, or the complete classpath must be traversed loading all classes to see what they do which sounds highly inefficient to me, or it is a completely different approach. What is the trick?

  • Regexing it up with IIS re-write module

A typical user's profile url would be http://www.mymark.com/mike Each user is also created a blog in a multi-user wordpress installation. The wordpress url would look like this: http://www.mymark.com/blog/mike I am trying to use the rewrite module to create more canonical urls for the user (http://www.mymark.com/mike/blog), and have tried several regex variations that I have created through RegExr(a regex generation tool) and come up with this as the pattern to match (www.|)mymark.com/([^/]+)/blog but haven't had any success so far. What am I doing wrong here? Here is a screen shot of my re-write rule:

  • Displaying Google Calendar event data on FullCalendar

    - by aurealus
    I am using Google Calendar as a storage engine for a calendar system I am building, however, I am using a single Google user account with multiple calendars, i.e. each user on my system has their own calendar within the one user account. I'm able to create a calendar per user just fine, but I would like to have FullCalendar retrieve the events for display purposes, without manually getting the magic cookie url from Google Calendar settings. I would like to be able to retrieve it programmatically or 'proxy' the feed via an authenticated call to get event data that I'm doing in Django. $('#calendar').fullCalendar({ events: $.fullCalendar.gcalFeed( "http://www.google.com/calendar_url/" <-- or /my/event/feed/url ) });

  • VBA Macro On Timer style to run code every set number of seconds, i.e. 120 seconds

    - by FinancialRadDeveloper
    I have a need to run a piece of code every 120 seconds. I am looking for an easy way to do this in VBA. I know that it would be possible to get the timer value from the Auto_Open event to prevent having to use a magic number, but I can't quite get how to fire off a timer to get something to run every 120 seconds. I don't really want to use an infinite loop with a sleep if I can avoid it.

  • Accessing constructor from abstract base class with reflection

    - by craesh
    Hi! I'm playing around with Java's Reflection. I have an abstract class Base with a constructor. abstract class Base { public Base( String foo ) { // do some magic } } I have some further classes extending Base. They don't contain much logic. I want to instantiate them with Base's constructor, without having to write some proxy contructors in those derived classes. And of course, I want to instantiate those derived classes with Reflection. Say: Class cls = SomeDerivedClass.class; Constructor constr; constr = cls.getConstructor( new Class[] { String.class } ); // will return null Class clsBase = Base.class; constr = clsBase.getConstructor( new Class[] { String.class } ); // ok Base obj = (Base) constr.newInstance( new Object[] { "foo" } ); // will throw InstantiationException because it belongs to an abstract class Any ideas, how I can instantiate a derived class with Base's constructor? Or must I declare those dumb proxy constructors?

  • Using emacs across many hosts

    - by mbac32768
    On a daily basis I: use multiple workstations running either Linux, Windows, or MacOS X edit files on additional Linux hosts that are not any of the workstations mentioned above The only common element here is that the internet connects all of these hosts: workstations and servers. I can keep all of the config files in sync on my workstations too and can run an X server on all of them. What's the right way of running emacs? I don't want to sacrifice any features. In my ideal world I can type 'emacs foo.txt' on a remote host and some magic happens via X forwarding to display the file in my workstation's existing emacs session. Non-solutions tramp: when I'm manipulating a remote host an editor is just part of my workflow. I need a terminal open so I can run other commands quickly. tramp is all wrong for this. ncurses emacs: sucks, I want the graphical kind If you don't have a positive answer to my question, please don't just guess. Thanks.

  • What is the best way to marshal a char array function argument?

    - by Seh Hui 'Felix' Leong
    Let say that given the following signature in LegacyLib.dll: int Login(SysInst *inst, char username[8], char password[6]); The simple way to marshal this function in C# would be: [DllImport("LegacyLib.dll", CharSet=CharSet.Ansi)] public static extern int Login(ref SysInst inst, string username, string password); The problem of doing it in a such a naive way is that the managed string we passed into the username or password parameter could be longer than the array bounds and this could potentially cause a buffer overrun in LegacyLib.dll. Is there a better way which overcomes this problem? i.e. is there any quick [MarshalAs(…)] magic that I could use to counter that?

  • Hide anchors using jQuery

    - by Eric Di Bari
    I've created a dynamic page that, depending on the view type, will sometimes utilize the anchor tags and other times not. Essentially, I want to be able to control if on click the page jumps to the anchor. Is it possible to hide anchor tags using jQUery, so they are essentially removed? I need to be able to re-enable the anchors when necessary, and always show the current anchor in the browser's address bar. It seems to work in FireFox, but not in Internet Explorer. I have three sections: the 'table of contents', the content, and the javascript (jQuery) code Table of Contents <a id="expandLink0" class="expandLinksList" href="#green">What is green purchasing</a><br> <a id="expandLink1" class="expandLinksList" href="#before">Before you buy</a><br> Contents <ul id="makeIntoSlideshowUL">' <li id="slideNumber0" class="slideShowSlide"> <a name="green"></a> <div>Green Purchasing refers to the procurement of products and service...<a href="#topOfPageAnchor" class="topOfPageAnchorClass">Back to Top</a></div> </li> <li id="slideNumber1" class="slideShowSlide"> <a name="before"></a> <div>We easily accomplish the first four bullet points under...<a href="#topOfPageAnchor" class="topOfPageAnchorClass">Back to Top</a></div> </li> </ul> jQuery On Page Load $(".slideShowSlide").each(function() { $(this).children(":first-child").hide(); }); jQuery to re-enable links $(".slideShowSlide").each(function() { $(this).children(":first-child").show(); });
