  • django admin app error (Model with property field): global name 'full_name' is not defined

    - by rxin
    This is my model: class Author(models.Model): first_name = models.CharField(max_length=200) last_name = models.CharField(max_length=200) middle_name = models.CharField(max_length=200, blank=True) def __unicode__(self): return full_name def _get_full_name(self): "Returns the person's full name." if self.middle_name == '': return "%s %s" % (self.first_name, self.last_name) else: return "%s %s %s" % (self.first_name, self.middle_name, self.last_name) full_name = property(_get_full_name) Everything is fine except when I go into admin interface, I see TemplateSyntaxError at /bibbase2/admin/bibbase2/author/ Caught an exception while rendering: global name 'full_name' is not defined It seems like the built-in admin app doesn't work with a property field. Is there something wrong with my code?

  • jQuery drag drop slower for more DIV items

    Hi there, I have got a hierarchichal tags (with parent child relationship) in my page and it will account to 500 - 4500 (can even grow). When i bound the draggable and droppable for all i saw very bad performance in IE7 and IE6. The custom helper wont move smoothly and was very very slow. Based on some other post i have made the droppable been bound/unbound on mouseover and mouseout events (dynamically). Its better now. But still i dont see the custom helper move very smoothly there is a gap between the mouse cursor and the helper when they move and gets very bad when i access the site from remote. Please help me to address this performance issue. Am totally stuck here.. :(

  • c# Attribute Question

    - by Petoj
    Well i need some help here i don't know how to solve this problem. the function of the attribute is to determine if the function can be run... So what i need is the following: The consumer of the attribute should be able to determine if it can be executed. The owner of the attribute should be able to tell the consumer that now it can/can't be executed (like a event). It must have a simple syntax. This is what i have so far but it only implements point 1, 3. [AttributeUsage(AttributeTargets.Method, AllowMultiple = false)] public class ExecuteMethodAttribute : Attribute { private Func<object, bool> canExecute; public Func<object, bool> CanExecute { get { return canExecute; } } public ExecuteMethodAttribute() { } public ExecuteMethodAttribute(Func<object, bool> canExecute) { this.canExecute = canExecute; } }

  • Response.Redirect in a COM+ Object Called from Classic ASP Page

    - by ajdams
    Basically we moved from IIS 5 to IIS 7 and I am trying to update some of our old COM objects to .NET by rewriting them in C#. What I am have so far is a Classic ASP page calling the COM+ object and then I am trying to do a simple redirect within the COM+ object (this is just for testing purposes, it's not what the object will do eventually). My problem/question is, why does the redirect call not work properly? Am I doing something wrong or can you not redirect within a COM+ object? All that happens is a blank white page comes up and if I check the IIS logs, I see no errors. Here is my code so far: In Classic ASP (the call to COM+) Set oBankReg = CreateObject("BVSRegistration.SignIn") oBankReg.GetBankId(bankid) Code in C# COM object: using System; using System.Web; using System.Text; using System.EnterpriseServices; using System.Collections.Generic; using System.Runtime.InteropServices; [assembly: ApplicationName("BVSRegistration")] [assembly: Description("COM+ upgrade of the BVSRegistration VB6 SignIn.cls.")] [assembly: ApplicationActivation(ActivationOption.Server)] [assembly: ApplicationAccessControl(false, AccessChecksLevel = AccessChecksLevelOption.ApplicationComponent)] namespace BVSRegistration { public class SignIn : ServicedComponent { public void GetBankId(string bankid) { HttpContext.Current.Response.Redirect("http://www.google.com"); } } } Any ideas? Thanks

  • Call a function by its name, given from string java

    - by Joao
    Hello, I would like to be able to call a function based on its name provided by a string. Something like public void callByName(String funcName){ this.(funcName)(); } I have searched a bit into lambda funcions but they are not supported. I was thinking about going for Reflection, but I am a bit new to programming, so I am not so familiar with the subject. This whole question was brought up on my java OOP class, when I started GUI (Swing, swt) programming, and events. I found that using object.addActionCommand() is very ugly, because I would later need to make a Switch and catch the exact command I wanted. I would rather do something like object.attachFunction(btn1_click), so that it would call the btn1_click function when the event click was raised. Thank you Joao

  • wcf class implementing two operation contracts in different service contracts with same name

    - by Archie
    Hello, I have declared two service contracts as follows: [ServiceContract] public interface IContract1 { [OperationContract] double Add(int ip); } [ServiceContract] public interface IContract2 { [OperationContract] double Add(double ip); } I have a class which implements these two contracts. I have created two end points for both the contracts. But I'm not able to access the service from client code. It displays a big error when i try to update the service reference as: Metadata contains an error that cannot be resolved.... There was no endpoint listening at ... etc. I know that you can't have two OperationContracts with the same name but is it possible to have two operation contracts in different service contracts with same name but different signature? Thanks.

  • Copy object into another

    Is there an easy way how to achieve this: MyObj : (id, name); MyObj myObj_1 = new MyObj(1, "Name 1"); MyObj myObj_2 = new MyObj(2, "Name 2"); instead of myObj_2.setName(myObj_1.getName()) etc do something as following: myObj_2.copyFrom(myObj_1) so that they are different instances, but have equal properties.

  • .Net: Prevent an object from being paged out (VirtualLock equivalent)

    - by Gene
    How would one go about keep an object in memory such that it won't be paged out by the OS in .Net? i.e. Something similar to VirtualLock, but operating on an object, such that if compacting occurs and the object is moved it still would not be paged out, etc.. (I suppose one could pin the object's, determine what pages it belongs to, and then VirtualLock those pages, but that seems non-desireable for many reasons.) If possible, could you point me to a reference or working sample? (C# ideally) Many thanks in advance!

  • Tomcat - virtualhosting - name / ip / port - based

    - by lisak
    Hey, what are the usage scenarios for these kinds of virtual hosting ? Name Based - typical tomcat virtual hosting, one HOME instance with many contexts, each as an individual host IP based / port based - multiple instances of tomcat ( how is it with performance and memory consuption?) running on IP aliases (virtual IPs) for one network adapter, usually behind http apache server that can run name based virtual hostings. Otherwise I can't figure out how would I forward requests in iptables/firewall based on IP address, which is just one. How is IP based virtual hosting done as to Tomcat and multiple instances ? I'd like to hear some usage scenarios from your experience. How are you running your applications. Cause there are applications having it's own modified classloader and they are developed in a way to run alone withing a tomcat instance. Then there are trivial applications which can run within one instance without problems. Many thanks

  • Programming related name for a kitten? [closed]

    - by andrhamm
    I am a programmer and I just got my first kitten. A Google search for nerdy/geeky cat names was unimpressive. She's a little black kitten with a very courageous and adventurous attitude! She has a little light gray spot on her chest which might turn white with time. Here she is on my Flickr Which name would you suggest? Which of these do you like? It should be something short that has a couple contrasting sounds so it stands out a bit when you say it. PHP is my favorite scripting language but it makes for a lousy name :P Java Pixel Perl Ruby Gizmo Mocha Thanks for the help!

  • Find package name for Android apps to use Intent to launch Market app from web

    - by eom
    I'm creating a mobile website that will include a page from which people can download relevant apps that we recommend. I've found instructions for creating the links to launch the Market but this assumes that you are the developer of the app in question and know the exact package name. Is there any way to get the package name, other than just contacting the developers and asking? Also, it turns out that those instructions don't really work for creating web hyperlinks. They only give you a URI to reference in a string of Java code in another Android app. Our site is in Drupal, so Java is not going to work. For the iPhone, I found easy instructions for getting the URL/link style I need from the iTunes store, so I'm looking for info like that.

  • What are possible reasons for java.io.IOException: "The filename, directory name, or volume label sy

    - by Turismo
    I am trying to copy a file using the following code: File targetFile = new File(targetPath + File.separator + filename); ... targetFile.createNewFile(); fileInputStream = new FileInputStream(fileToCopy); fileOutputStream = new FileOutputStream(targetFile); byte[] buffer = new byte[64*1024]; int i = 0; while((i = fileInputStream.read(buffer)) != -1) { fileOutputStream.write(buffer, 0, i); } For some users the targetFile.createNewFile results in this exception: java.io.IOException: The filename, directory name, or volume label syntax is incorrect at java.io.WinNTFileSystem.createFileExclusively(Native Method) at java.io.File.createNewFile(File.java:850) Filename and directory name seem to be correct. The directory targetPath is even checked for existence before the copy code is executed and the filename looks like this: AB_timestamp.xml The user has write permissions to the targetPath and can copy the file without problems using the OS. As I don't have access to a machine this happens on yet and can't reproduce the problem on my own machine I turn to you for hints on the reason for this exception.

    Hi, When I bind a mousemove event to an element it is working smoothly with every browser except Internet Explorer. With IE the CPU usage is way too much and some associated things (eg. tooltip) are ugly. Is there any way I could rid of the performance problem? (yeah I know, don't use IE :))
