  • Sorting related objects in the Django Admin form interface

    - by Carver
    I am looking to sort the related objects that show up when editing an object using the admin form. So for example, I would like to take the following object: class Person(models.Model): first_name = models.CharField( ... ) last_name = models.CharField( ... ) hero = models.ForeignKey( 'self', null=True, blank=True ) and edit the first name, last name and hero using the admin interface. I want to sort the objects as they show up in the drop down by last name, first name (ascending). How do I do that? Context I'm using Django v1.1. I started by looking for help in the django admin docs, but didn't find the solution As you can see in the example, the foreign key is pointing to itself, but I expect it would be the same as pointing to a different model object. Bonus points for being able to filter the related objects, too (eg~ only allow selecting a hero with the same first name)

  • Difference between Class Abstraction and Object Interfaces in PHP?

    - by Mark Tomlin
    What is the difference between a Class Abstraction and an Object Interfaces in PHP? I ask because, I don't really see the point to both of them, they both do the same thing! So, what are the advantages of disadvantages using both against one or the other? Class Abstraction: abstract class aClass { // Force extending class to define these methods abstract public function setVariable($name, $var); abstract public function getHtml($template); } Object Interface: interface iClass { // Force impementing class to define these methods public function setVariable($name, $var); public function getHtml($template); }

  • Understanding reflection

    - by sdmiller
    I recently started work at a new company and a .net web application we have is built using reflection. I have only been out of school for a year and haven't worked with this concept. After studying the code... it looks like there is a single backend interface of type object that has about 20 classes that inherit from it. lots of generic gets and sets On the surface it looks like standard inheritance to me. I guess my question is, what makes this reflection? Is it because the interface is not strongly typed? Thanks

  • ASP.NET Custom Control With A Property That Is An Interface

    - by user129674
    I want to have a property on my custom control that is an interface type. For example: [ ToolboxData("<{0}:MyTextBox runat=server></{0}:MyTextBox"), ParseChildren(true, "Validation") ] class MyTextBox : WebControl { [ Category("Behavior"), Description("The validation to use"), DesignerSerializationVisibility(DesignerSerializationVisibility.Content), PersistenceMode(PersistenceMode.InnerDefaultProperty) ] public IValidation Validation { get; set; } } Then when I go to use my control in a web form I would like to be able to do: <my:MyTextBox ID="txt" runat="server"> <my:FancyValidator /> </my:MyTextBox> That way I will be able to define one class that could use any number of validators. When I try and do this now, I end up with an error saying: Type 'IValidator' does not have a public property named 'FancyValidator' What do I need to do to make this work? Thanks!

  • How does transmission created it's cross plataform app? It has from Qt/Mac to CLI interfaces!

    - by Somebody still uses you MS-DOS
    I'm amazed at Transmission, a BT client. It has a Mac, a GTK+, a QT, a Web Client and a CLI interface to it. I tried reading some of it's source to understand how he creates all these interfaces, but no luck. Does the developer creates them using a single ide? Or does he create the interface logic in each specific environment (specially mac), "exports" this window code and integrates with the main logic? How did the developers create this software with so many interfaces?

  • Build common interface for two applications(one is in .asp, other in java)

    - by govardhan
    We have two applications. One application in .asp and second application in java. we want to build interface for universal authentication, so that one can access the other application once signed into one application. Both applications are using SQL database, but one is written in .ASP hosted on Windows server while the other is in JAVA hosted on a Linux server. The applications are currently resided on two different servers. requirements: 1)The end user are most likely to access the applications through .ASP first, then reach the 2nd application more like "back office" management system. 2)he JAVA application currently works well with IE web browser, but not very smooth with other browsers such as Firefox. Would like to make the application to be more compatible with other browsers. Please help me, its very important to me. Thanks in advance!

  • Cross platform, Interactive text-based interface with command completion

    - by trojanfoe
    Does anyone know of a C++ library that will provide a text-based interactive interface? I want to create two versions of an application; a console based program that will perform whatever actions are given on the command line or interactively at the console as well as a GUI based program (Mac Cocoa and Windows MFC). Both versions will share a common C++ backend. For the console based program I would like similar history abilities to readline (which I cannot use as this application will be closed source) with command completion (Tab-activated for example). Perhaps there is something like this already available?

  • C# compiler fails to recognize a class is implementing an interface

    - by Freek
    The following code fails to compile (using VS2010) and I don't see why. The compiler should be able to infer that List is 'compatible' (sorry for lack of a better word) with IEnumerable, but somehow it doesn't. What am I missing here? interface ITest { void Test(); } class TestClass : ITest { public void Test() { } } class Program { static void Test(IEnumerable<ITest> tests) { foreach(var t in tests) { Console.WriteLine(t); } } static void Main(string[] args) { var lst = new List<TestClass>(); Test(lst); // fails, why? Test(lst.Select(t=>t as ITest)); //success Test(lst.ToArray()); // success } }

  • Drawing lines between windows just like in Interface Builder

    - by Koning Baard
    I have two windows, each with a round NSView: ------------------ ------------ |X-+ Oscillator | |X-+ Mixer | |----------------| |----------| | | | | | O | | O | | | | | | | | | ------------------ ------------ Both windows are in a seperate NIB. I want to be able to draw a line between the two round NSViews at runtime, using drag'n'drop, just like connecting IBOutlets in Interface Builder: ------------------ ------------ |X-+ Oscillator | |X-+ Mixer | |----------------| |----------| | | | | | O-------+-----+-----O | | | | | | | | | ------------------ ------------ I also want to be able to determine to which NSViews the NSViews are connected using the drawn lines. I need this to connect Oscillators to Mixers. I also want to be able to remove the connections by dragging into empty space. Can anyone explain me how to do this? Thanks.

  • C# creating a custom user interface

    - by CSharpInquisitor
    Hi, I have a SQL database holding a number of numeric and text values that get updated regularly. The exact number/type/names of these data points can change depending on the source of the database writes. I would like to create a user interface editor, where the user can add database points to the UI and arrange them and format them as they want. If a new point is added to the database they can right click on the UI and say "add this point" and choose from a list of database points. I'm looking for some pointers on where to start on creating this editor application, could something clever be done using XAML to dynamically create std WPF controls at runtime? Thanks in advance for any help, Si

  • Calling inheriting class methods via interface.

    - by Stacey
    Given the scenario... interface IBase{ void Process(int value); } abstract class Base : IBase { public virtual void Process(int value){ throw new NotImplementedException(); } } class Implemented: Base, IBase { public void Process(int value) { // .. some code here.. } } I'm trying to write a loop similar to the following. foreach( Base b in CollectionOfImplemented ) { b.Process( // something will go here // ); } Trying this, it keeps calling Base.Process, instead of Implemented.Process; but the type in the collection is Implemented, not Base. Boxing it seems to work, but I was hoping to see if I could find a more intelligent approach to it, since the Collection will contain other types of objects that also inherit from Base.

  • How should 4 decimals places behave, being simple yet powerful

    - by vener
    I have a UI question that troubled me on the best method to handle 4 decimal places for prices. In an table already cramped full of data, I would want to simplified the interface to make it not so cluttered. The actual current UI is shown below. http://i41.tinypic.com/bg5tub.jpg The problem is, for a unit price/units/D.Price and Dis.(Discount) to have 4 decimal places ($0.3459) is quite rare but it still happens (5 in 100 entries). This will result a lot of junk decimal places, cluttering up the interface. What is the best solution to this problem? In short, I want to declutter it yet maintain the precision. Note: This is web app

What modification should I do to get rid of it? Thanks Nayn

  • How to implement fluent interface with a base class, in C++

  • Multiple SVN repos on Debian HTTPd vhost setup

    - by Jonathon Reinhart
    I would like to have my svn/http server setup so I can access multiple repositories via a "svn" subdomain: https://svn.example.com/repo1 https://svn.example.com/repo2 I am using Debian 6, and already have multiple vhosts set up via the standard sites-available method. Resources and their problems: How To: subversion SVN with Apache2 and DAV This one doesn't deal with a server with multiple vhosts. Installing and Configuring Subversion This one only considers one subversion repository. This one does show putting the SVN DAV <Location> in the svn vhost file. However, it doesn't say whether to put it inside or outside the <VirtualHost> tag. Does this really limit the subversion access to just that vhost? I just tried, and can access /foorepo from any subdomain. Setting Up Subversion And Trac As Virtual Hosts On An Ubuntu Server This one appears to be very close, but I can still access repos from any vhost. In other words, it doesn't matter what subdomain I specify, as long as the path matches the repo name. Doesn't make any sense. And yes, my <Location> tag is inside the <VirtualHost>. A lot of these articles seem to have been written in 2006 or earlier, and don't necessarily conform to the configuration methods that newer distros are using. Can anyone guide me in the right direction?

  • New monitor connected to HDMI adaptor doesn't show output after booting

    - by Paul
    Hello out there in the multiple monitors’ world. I am a very old newbie in your world and need help. I just purchased a new Asus VH236H monitor and hooked it up the HDMI port of an ATI Radeon HD4300 / 4500 Series display adaptor. I left the old Princeton LCD19 (TMDS) hooked up to the DVI port of the same display adaptor. Both monitors displayed the boot sequence, after I fired good old Sarastro2 (Asus P5Q Pro Turbo – Dual Core E5300 – 2.60 GHz) up. The Asus lacked one half of a second behind the Princeton until the Windows 7 Ultimate SP 1 boot up was complete. Then the Asus displayed “HDMI NO SIGNAL” and went into hibernation. The Princeton stayed lit up as before. Both monitors are displayed on the “Screen Resolution Setup Display” and I plaid around with them for a while. The only thing I accomplished was to shove the desktop icons from the Princeton to the still hibernating Asus. The “Multiple displays:” is set to “Extend these displays”, the Orientation is “Landscape” and the Resolutions are set on both to the “recommended” one. Both monitors show that they work properly in the advanced Properties display. What am I doing wrong, what am I missing? Never mind the opinions about the different resolutions of the two monitors. I always can unhook the Princeton and give it to a Goodwill Store if I do not like the setup. I just would like to make it work. Any constructive help is very much appreciated, Thank you.

  • IPTables: NAT multiple IPs to one public IP

    - by Kaemmelot
    I'm looking for a way how to nat 2 or more inner IPs (in my case xen doms) to one outer IP. I tried to use iptables -t nat -A PREROUTING -d 123.123.123.123 -j DNAT --to 1.2.3.4 --to 1.2.3.7 iptables -t nat -A POSTROUTING -s 1.2.3.4 -j SNAT --to 123.123.123.123 iptables -t nat -A POSTROUTING -s 1.2.3.7 -j SNAT --to 123.123.123.123 And got an error: iptables v1.4.14: DNAT: Multiple --to-destination not supported Try `iptables -h' or 'iptables --help' for more information. I found this in the manpage: Later Kernels (= 2.6.11-rc1) don't have the ability to NAT to multiple ranges anymore. So my question is: Why is it not possible anymore and is there a workaround? Maybe I should use an other method I don't know yet? EDIT: The idea is to use the system like a router, so I have one address but multiple users behind. The problem is I don't know which connection reffers to a user (for example 1.2.3.4). But I know, they all have different ports open for incomming traffic. So my solution (for DNAT) would be to nat all incoming connections to all users and filter all unused ports, so the connection goes to one single user. For outgoing traffic I would use iptables -A FORWARD -i eth0 -d 1.2.3.4 -m state --state ESTABLISHED,RELATED -j ACCEPT

  • Setting up Apache with multiple virtual host when using Plone 4.1

    - by Shaun Owens
    I have a Plone server running on CentOS, I have multiple instances of Plone running 4.0 and 4.1, I also have multiple sites. I am new to linux and haveing problems getting Apache to work with multiple virtuale hosts. The first host listed works just fine but the second host does not. I get the following error message when I start HTTPD: Starting httpd: [Mon Nov 07 14:38:31 2011] [warn] VirtualHost ordevel3.ucdavis.edu:80 overlaps with VirtualHost ordevel4.ucdavis.edu:80, the first has precedence, perhaps you need a NameVirtualHost directive.

  • routing through multiple subinterfaces in debian

    - by Kstro21
    my question is as simple as the title, i have a debian 6 , 2 NICs, 3 different subnets in a single interface, just like this: auto eth0 iface eth0 inet static address 192.168.106.254 netmask 255.255.255.0 auto eth0:0 iface eth0:0 inet static address 172.19.221.81 netmask 255.255.255.248 auto eth0:1 iface eth0:1 inet static address 192.168.254.1 netmask 255.255.255.248 auto eth1 iface eth1 inet static address 172.19.216.3 netmask 255.255.255.0 gateway 172.19.216.13 eth0 is conected to a swith with 3 differents vlans, eth1 is conected to a router. No iptables DROP, so, all traffic is allowed. Now, passing the traffic through eth0 is OK, passing the traffic through eth0:0 is OK, but, passing the traffic through eth0:1 is not working, i can ping the ip address of that sub interface from a pc where this ip is the default gateway, but can't get to servers in the subnet of the eth1 interface, the traffic is not passing, even when i set the iptables to log all the traffic in the FORWARD chain and i can see the traffic there, but, the traffic is not really passing. And the funny is i can do any the other way around, i mean, passing from eth1 to eth0:1, RDP, telnet, ping, etc, doing some work with the iptable, i manage to pass some traffic from eth0:1 to eth1, the iptables look like this: iptables -t nat PREROUTING -d 192.168.254.1/32 -p tcp -m multiport --dports 25,110,5269 -j DNAT --to-destination 172.19.216.1 iptables -t nat PREROUTING -d 192.168.254.1/32 -p udp -m udp --dport 53 -j DNAT --to-destination 172.19.216.9 iptables -t nat PREROUTING -d 192.168.254.1/32 -p tcp -m tcp --dport 21 -j DNAT --to-destination 172.19.216.11 iptables -t nat POSTROUTING -s 172.19.216.0/24 -d 172.19.221.80/29 -j SNAT --to-source 172.19.221.81 iptables -t nat POSTROUTING -s 172.19.216.0/24 -d 192.168.254.0/29 -j SNAT --to-source 192.168.254.1 iptables -t nat POSTROUTING -s 172.19.216.0/24 -o eth0 -j SNAT --to-source 192.168.106.254 dong this is working, but,it is really a headache have to map each port with the server, imagine if i move the service from server, so, now i have doubts: can debian route through multiple subinterfaces?? exist a limit for this?? if not, what i'm doing wrong when i have the same setup with other subnets and it is working ok?? without the iptables rules in the nat, it doesn't work thanks and i hope good comments/answers

  • How to distribute multiple executions of an app across many machines

    - by Salec
    I've got a simulation app (64-bit windows) that runs without any user interaction. This app gathers information and pushes it to a remote MS SQL Server. What I'd like to do is execute this simulation as many times as I can on multiple machines after our nightly build has finished and it has passed the test suite. If possible I'd love to have the ability to configure it to stop after x total runs or if the entire batch has taken over y hours. I've tried using Visual Studio's built in test framework since we already have a test lab set up with multiple agents. I created a single unit test that simply runs the simulation then I created an ordered test and added that single test multiple times (from what I gather, this is the only way to execute the same unit test more than once). I found that ordered tests are only run on a single agent and not distributed which is very limiting. We use TeamCity to perform our nightly builds and I suspect it's possible to implement this on top of that, but I'm fairly new to TeamCity. We also have Jenkins and Bamboo available and I'm open to any other software that would get the job done presuming it runs on a 64-bit Windows OS. Any suggestions?

  • Windows 8 install app for multiple user accounts

    - by Robert Graves
    I purchased Adera episode 2 intending to play through it with my son. We each have our own user account on the same PC. When my son logged in, he was prompted to purchase the app which I had already purchased, installed, and played on the same PC. So I checked the Terms of Use. After selecting an app in the store, there is a Terms of Use link on the left side under the Install button. It is almost impossible to identify it as a link unless you put your mouse over it. The Terms of Use are standard across all apps in the store, not specific to particular apps. The terms of use indicates that the app may be installed on up to five devices, but says nothing about multiple user accounts on those devices. However, this Microsoft blog article indicates that it is allowed. Say, for example, that your family has a shared PC. You have previously used your Microsoft account to purchase a game that all your kids like to play. You can install it for each of your kids by having each of them sign in to their Windows accounts on the shared PC, then launch the Store and sign in to the Store using your own Microsoft account. There, you’ll see all your apps and you can re-install the app on your kid’s Windows account. Installing apps on multiple user accounts on a shared PC still only counts as one of the five allowable PCs where you can install apps. So I have two questions: Is it permissible under the Terms of Use to install the app under multiple accounts on the same device? If so, how do I do so given that my son has already signed into the store using his own Microsoft account.

  • What are good reasons to use explicit interface implementation for the sole purpose of hiding members?

    - by Nathanus
    During one of my studies into the intricacies of C#, I came across an interesting passage concerning explicit interface implementation. While this syntax is quite helpful when you need to resolve name clashes, you can use explicit interface implementation simply to hide more "advanced" members from the object level. The difference between allowing the use of object.method() or requiring the casting of ((Interface)object).method() seems like mean-spirited obfuscation to my inexperienced eyes. The text noted that this will hide the method from Intellisense at the object level, but why would you want to do that if it was not necessary to avoid name conflicts?
