  • Any working tutorials for Authlogic?

    - by Mark Wilbur
    I've been trying to build my first rails app and have gotten stuck on the issue of user authentication. I've found a number of tutorials for using various plug-ins to do this, but so far every single one of them is out-dated, and as a result, broken! From what I've read, I think Authlogic may be the best fit for me, and I've tried two things: 1) Going through Railscast, episode #160 (which is a tutorial for setting it up) 2) Using Ryan B's nifty_authentication gem with the --authlogic tag In both cases, I get the following error as soon as I try to do anything with a user: undefined local variable or method `acts_as_authentic' for # I believe this is from the User model: class User < ActiveRecord::Base acts_as_authentic end I'm sure I've installed the authlogic gem, and I've added config.gem "authlogic" to my environment.rb Any ideas about what's wrong? Anybody know of a complete and up to date tutorial for adding user authentication?

    - by jaderanderson
    Well, the question is kinda simple. I have a object defined as: public class FullListObject : System.Collections.ArrayList, IPagedCollection And when i try to: IPagedCollection pagedCollection = (IPagedCollection)value; It don't work... value is a FullListObject... this is my new code trying to get around a issue with the "is" operator. When the system tests (value is IPagedCollection) it never gets true for FullListObject. How to cast the object to another object with a interface type?

  • Using Propel ORM in my own custom classes

    - by Stick it to THE MAN
    I am refactoring a few classes I wrote a while ago, into my Symfony project (v1.3.2 with Propel ORM). The classes originally used direct connections to the database, I want to refactor those classes (stored in $(SF_LIB_DIR)) so that I can call propel and also use the ORM objects. To clarify, So for example, I want to be able to use code like this in my custom classes: try { $con = Propel::getConnection(); $c = new Criteria(); $foo = new PropelORMFooObject(); $foobar = PropelORMFooBarObjectPeer::fetch($c); //set fields etc $foo->setFooBar($foobar); // now save using obtained connection .. $foo->save($con) }catch(SomeException $e) { //deal with it } I assume that I will need to add some require_once() statements to my custom libraries, but it is not clear which files to include. Does anyone know how to do this?

  • Windows Live Writer plugin with .NET 4

    - by Steve Dunn
    Has anyone written a plugin for Windows Live Writer that runs against .NET 4? I've read the .NET 4 introduces side-by-side running, so one part of the app can target .NET x and another part can target .NET 4. I thought WLW would be a good starting point to try this as previously it only supported plugins up to .NET 2. But my .NET 4 plugin never shows. Maybe they test dependencies before loading the plugins? Anyone else got this working?

    - by Jlbelmonte
    Hi, I've been looking and googling a lot, but I didn't find a solution to this problem. I was successfully using xrandr to extend my desktop in my work place with this little "script". #!/bin/sh xrandr --newmode 1920x1080 220.64 1920 2056 2264 2608 1080 1081 1084 1128 -HSync +Vsync xrandr --addmode VGA 1920x1080 xrandr --output VGA --mode 1920x1080 Everything was going well till one day that magically stop working. When I try to use it. I just get this message. X Error of failed request: BadName (named color or font does not exist) The laptop display resizes in a strange way, but nothing happens with the extended monitor. I've restored gnome desktop default config. I changed the font config, I tried with other layouts and monitors, but always occur the same. So any Idea will be welcomed. My best regards.

  • EF 4.0 - Many to Many relationship - problem with deletes

    - by chugh97
    My Entity Model is as follows: Person , Store and PersonStores Many-to-many child table to store PeronId,StoreId When I get a person as in the code below, and try to delete all the StoreLocations, it deletes them from PersonStores as mentioned but also deletes it from the Store Table which is undesirable. Also if I have another person who has the same store Id, then it fails saying "The DELETE statement conflicted with the REFERENCE constraint \"FK_PersonStores_StoreLocations\". The conflict occurred in database \"EFMapping2\", table \"dbo.PersonStores\", column 'StoreId'.\r\nThe statement has been terminated" as it was trying to delete the StoreId but that StoreId was used for another PeronId and hence exception thrown. Person p = null; using (ClassLibrary1.Entities context = new ClassLibrary1.Entities()) { p = context.People.Where(x=> x.PersonId == 11).FirstOrDefault(); List<StoreLocation> locations = p.StoreLocations.ToList(); foreach (var item in locations) { context.Attach(item); context.DeleteObject(item); context.SaveChanges(); } }

  • avaudioplayer interferes with mpmovieplayer on ipad

    - by user175826
    my app plays video and audio. however, i have a problem where once i play an audio file using avaudioplayer, the video refuses to play. when i play the video first, everything is fine. but if the audio is played first, any time i try to play the video it simply pops up the video player but will not play the actual video (you can use the scroller to go to any point in the video, but no playback will happen). this issue does not come up on the iphone, nor on the ipad simulator. clearly there is some resource conflict here, probably related to the audio, and i'd welcome some input on how to address it.

  • How to silently import a Certificate into a specific Certificate Store?

    - by Adriaan
    I am attempting to import a Certificate into the Current User - Personal store using the command line "importpfx -f [certificate name.p12] -p [password] -t USER -s Personal". It works, but for reasons I don't understand there are now two Personal stores under the Current User, and the imported certificate is in the new Personal store. When I try to connect to the website of [well-known money transfer service], it fails. However, if I manually import the certificate using MMC into the original Personal store, it works. My question is: How can I force IMPORTPFX to import the certificate into the original Personal store, and how can I delete the new Personal store? Context: I need to do a silent import of certificates on 3000+ remote point-of-sale devices, so it needs to be a silent install via PSEXEC (SysInternals).

  • touchesEnded not being called??? or randomly being called

    - by Rob
    If I lift my finger up off the first touch, then it will recognize the next touch just fine. It's only when I hold my first touch down continuously and then try and touch a different area with a different finger at the same time. It will then incorrectly register that second touch as being from the first touch again. Update It has something to do with touchesEnded not being called until the very LAST touch has ended (it doesn't care if you already had 5 other touches end before you finally let go of the last one... it calls them all to end once the very last touch ends) - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { UITouch* touch = [touches anyObject]; NSString* filename = [listOfStuff objectAtIndex:[touch view].tag]; // do something with the filename now } - (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event { ITouch* touch = [touches anyObject]; NSString* buttonPressed = [listOfStuff objectAtIndex:[touch view].tag]; // do something with this info now }

  • External Reference to Richfaces modal

    - by John
    Hi, I need to get a <rich:modalPanel id="mod1" .../> component to load an external page on "show" action, defined as: <a4j:commandButton value="link" id="l1" reRender="mod1" oncomplete="Richfaces.showModalPanel('mod1')"> <f:setPropertyActionListener target="#{mybean.someParam}" value="#{myOtherbean.someOtherparam}" /> </a4j:commandButton> . My first try was with <rich:modalPanel id="mod1"> <ui:include src="#{mybean.generateURL()"/> </rich:modalPanel> but it just throws me a 404 page not found error, typing the generated URL directly into the address bar works perfectly fine. Does anyone know what's causing the problem , or what's the correct way to do this? The system is running on seam/richfaces. Thanks!

    - by H4mm3rHead

  • How do you work out the IIS Virtual Path for an application?

    - by joshcomley
    When I try to change the ASP.NET version to v4 on IIS 6, I receive the following warning: Changing the Framework version requires a restart of the W3SVC service. Alternatively, you can change the Framework version without restarting the W3SVC service by running: aspnet_regiis.exe -norestart -s IIS-Viirtual-Path Do you want to continue (this will change the Framework version and restart the W3SVC service)? How do I work out IIS-Virtual-Path? I have tried the obvious paths i.e.: aspnet_regiis.exe -norestart -s "/WebSites/Extranet/AppName" Where WebSites is the name of the folder in IIS, Extranet the name of the root app and AppName the name of the Virtual Directory application I am trying to change. Thanks! Edit: How do I work out the virtual path for the Auth virtual directory in following IIS6 setup: I have tried: aspnet_regiis.exe -norestart -s "/Web Sites/Extranet/Auth" aspnet_regiis.exe -norestart -s "Auth" I get: Installation stopped because the specified path (WhateverIPutIn) is invalid.

  • Using devise with Rails 3 beta

    - by Terw
    I'm currently trying to use Devise 1.1.pre3 as authentication in my upcoming project, but I can't get it to work properly. I have done everything it says in the documentation, installed warden and the correct Devise version, run the install and used the generator to create the model. But when I try to access the sign up form (localhost:3000/users/sign_up) all I get is No route matches "/users/sign_up" But when I run rake routing I get the following: ... GET /users/sign_up(.:format) {:controller=>"devise/registrations", :action=>"new"} ... I doesn't have any files matching that controller. Is there any steps I have missed (installed, updated routing etc and created model)

  • reading a BYTE as a DWORD in Masm

    - by Help I'm in college
    Hi, once again I'm doing MASM programming. I'm trying to write a procedure using the Irvine32 library where the user enters a string which is put into an array of BYTEs with ReadString. Then it loops over that arrray and determines if each character is a number. However, when I try cmp [buffer + ecx], 30h MASM complains about comparing two things that are not the same size. Is there anyway I could read the ASCII code in each BYTE in the array as a DWORD (or otherwise extract the ASCII value in each BYTE)?

  • How do I upgrade my Crystal Report libraries in a .NET 3.5 project to CR XI R2?

    - by Stuart B
    Our project currently uses Crystal Reports for Visual Studio 2008. We need to upgrade to XI R2, but I'm having problems doing so. Here are the steps I followed: Install Crystal Reports XI R2. Collect updated assemblies from the GAC. I did this because I couldn't find version XI libraries in the "Add References..." dialog. I verified that these assemblies were of version 11.5.*. The libraries I gathered were: CrystalDecisions.CrystalReports.Engine CrystalDecisions.Enterprise.Framework CrystalDecisions.Enterprise.InfoStore CrystalDecisions.ReportSource CrystalDecisions.Shared CrystalDecisions.Windows.Forms Replace all references in my projects to version 10.5 Crystal libraries with references to the newer assemblies. Everything builds fine, but when I try to instantiate a ReportDocument, I get this error: The type initializer for 'CrystalDecisions.CrystalReports.Engine.ReportDocument' threw an exception. Is there anything I'm missing? Will this just not work?

  • Visual Studio 2008 Unexpected Error on Project Checkout with VSS 2005

    - by Cyberherbalist
    I've encountered an odd misbehavior of VS 2008's integration with Visual Source Safe 2005. Situation occurs when I fire up VS2008 when a project is checked out to someone else, and later they check the project back in, while I still hold the VS2008 open. If I at that time add a new item, VS2008 tells me that my action has caused a check out of the project and a new version has been loaded from source control. Fair enough, but thereafter I get an error dialog stating "Visual Studio has encountered an unexpected error" with OK at every subsequent action, such as save file and search text, making it almost unusable. This is overcome by closing VS (which pops the error dialog once more) and restarting. Is there some kind of fix or workaround to this (besides the obvious ones: "don't try to check out the project when it's checked out to someone else", or "get latest version if you think the other person may have checked the project back in")?

  • How do I properly embed third-party frameworks in my Cocoa application?

    - by Jordan Kay
    I am writing a Cocoa application that makes use of the ParseKit framework (http://www.parsekit.com/). I've included the Framework in the proper folder, added a Copy Files build phase, and added it to the build phase. I can build and launch the application on my Mac. However, when I try to run it on another Mac, it crashes. The Console shows the following error message: dyld: Library not loaded: /Users/Jordan/Files/ParseKit/build/Debug/ParseKit.framework/Versions/A/ParseKit It looks like when the app launches, it is looking for the framework on my local drive. However, the framework is in the Copy Files build phase, so it has been copied into that application's Contents/Frameworks folder. If if the application were looking in this folder, it would be able to load the framework just fine, but for some reason it's looking for it on my local drive on the original Mac (which obviously doesn't exist on the other Mac). What am I doing wrong?

  • Error 2006: "MySQL server has gone away" using Python, Bottle Microframework and Apache

    - by Jamie
    After accessing my web app using: - Python 2.7 - the Bottle micro framework v. 0.10.6 - Apache 2.2.22 - mod_wsgi - on Ubuntu Server 12.04 64bit; I'm receiving this error after several hours: OperationalError: (2006, 'MySQL server has gone away') I'm using MySQL - the native one included in Python. It usually happens when I don't access the server. I've tried closing all the connections, which I do, using this: cursor.close() db.close() where db is the standard MySQLdb.Connection() call. The my.cnf file looks something like this: key_buffer = 16M max_allowed_packet = 128M thread_stack = 192K thread_cache_size = 8 # This replaces the startup script and checks MyISAM tables if needed # the first time they are touched myisam-recover = BACKUP #max_connections = 100 #table_cache = 64 #thread_concurrency = 10 It is the default configuration file except max_allowed_packet is 128M instead of 16M. The queries to the database are quite simple, at most they retrieve approximately 100 records. Can anyone help me fix this? One idea I did have was use try/except but I'm not sure if that would actually work. Thanks in advance, Jamie
