  • Django: How to get current user in admin forms

    - by lazerscience
    In Django's ModelAdmin I need to display forms customized according to the permissions an user has. Is there a way of getting the current user object into the form class, so that i can customize the form in its __init__ method? I think saving the current request in a thread local would be a possibility but this would be my last resort think I'm thinking it is a bad design approach....

  • Best practices for custom http user-agent strings?

    - by Noufal Ibrahim
    I'm developing an application that communicates with an internal web service using HTTP. Are there any "best practices" for custom user-agent strings so that I can put a nice one in my app? It's a Python library and the lower transport is Python's own httplib. Should the user-agent string say that or something else?

  • How do you test the usability of your user interfaces

    - by Martin
    How do you test the usability of the user interfaces of your applications - be they web or desktop? Do you just throw it all together and then tweak it based on user experience once the application is live? Or do you pass it to a specific usability team for testing prior to release? We are a small software house, but I am interested in the best practices of how to measure usability. Any help appreciated.

  • Writing user stories for internal technical tasks

    - by John Nolan
    I am attempting to manage my projects a little better so I am looking at attempting to apply some of (eventually all) the features of scrum. Looking at user stories specifically the high level format seems to be: As a User I can Feature Description or Artifact is Doing Something How would I write "Upgrade the Database"? Is it simply Upgrade the Database? I think I am being thrown off as there is no specific actor/customer and that the customer is the IT department.

  • User accounts in Symfony?

    - by gruner
    I'm new to Symfony. Is my understanding correct that the User class is actually for controlling sessions? But is there built-in login and account creation? I'm not finding it. But if there's an admin backend generator, how can it function without user logins?

  • User input without waiting for enter

    - by Hermann Ingjaldsson
    I am trying to make an interactive shell script in perl. The only user input I can find is the following: $name = <STDIN>; print STDOUT "Hello $name\n"; But in this the user must always press enter for the changes to take effect. How can I get the program to proceed immediately after a button has been pressed?

  • JavaScript Trigger window.open When a User Clicks Anywhere on Page

    - by Joe Hammonds
    I have a problem that I have been trying to figure out and haven't been able to get past it because Chrome/FireFox/IE do not publicly publish their "rules" for pop up blocking when it comes to JavaScript, Flash, etc. I am trying to trigger a window.open() when a user clicks anywhere on page. I've tried this: document.onclick = window.open("http://msn.com"); But all 3 browsers are blocking the popup, even though it is a user interaction.

  • Using a user-defined type as a primary key

    - by Chris Kaminski
    Suppose I have a system where I have metadata such as: table: ====== key name address ... Then suppose I have a user-defined type described as so: datasource datasource-key A) are there systems where it's possible to have keys based on user-defined types? B) if so, how do you decompose the keys into a form suitable for querying? C) is this a case where I'm just better off with a composite primary key?

  • Installation procedure RAC One Node

    - by rene.kundersma
    Okay, In order to test RAC One Node, on my Oracle VM Laptop, I just: - installed Oracle VM 2.2 - Created two OEL 5.3 images The two images are fully prepared for Oracle 11gr2 Grid Infrastructure and 11gr2 RAC including four shared disks for ASM and private nics. After installation of the Oracle 11gr2 Grid Infrastructure and a "software only installation" of 11gr2 RAC, I installed patch 9004119 as you can see with the opatch lsinv output: This patch has the scripts required to administer RAC One Node, you will see them later. At the moment we have them available for Linux and Solaris. After installation of the patch, I created a RAC database with an instance on one node. Please note that the "Global Database Name" has to be the same as the SID prefix and should be less then or equal to 8 characters: When the database creation is done, first I create a service. This is because RAC One Node needs to be "initialized" each time you add a service: The service configuration details are: After creating the service, a script called raconeinit needs to run from $RDBMS_HOME/bin. This is a script supplied by the patch. I can imagine the next major patch set of 11gr2 has this scripts available by default. The script will configure the database to run on other nodes: After initialization, when you would run raconeinit again, you would see: So, now the configuration is ready and we are ready to run 'Omotion' and move the service around from one node to the other (yes, vm competitor: this is service is available during the migration, nice right ?) . Omotion is started by running Omotion. With Omotion -v you get verbose output: So, during the migration you will see the two instance active: And, after the migration, there is only one instance left on the new node:

  • disable shutdown/suspend if there is other user logged in via ssh

    - by Denwerko
    I remember that in versions of ubuntu around 9.04 was possible to disable user to shutdown ( and maybe suspend too ) system if there was other user logged in.Something like policykit or similar. Is it possible to do in 11.04 ? Thanks edit: if someone needs ( for own risk ), little change in /usr/lib/pm-utils/bin/pm-action will allow user to suspend machine if he is only user logged in or when user will run sudo pm-suspend. Probably not best piece of code, but for now works. diff -r 805887c5c0f6 pm-action --- a/pm-action Wed Jun 29 23:32:01 2011 +0200 +++ b/pm-action Wed Jun 29 23:37:23 2011 +0200 @@ -47,6 +47,14 @@ exit 1 fi +if [ "$(id -u )" == 0 -o `w -h | cut -f 1 -d " " | sort | uniq | wc -l` -eq 1 ]; then + echo "either youre root or root isnt here and youre only user, continuing" 1&2 + else + echo "Not suspending, root is here or there is more users" 1&2 + exit 2 + fi + + remove_suspend_lock() { release_lock "${STASHNAME}.lock" Question still stands, is it possible to forbid shutdown or suspend when there is more than one user logged in ( without rewriting system file )?

  • User.Identity.Name returning NT AUTHORITY\NETWORK SERVICE i want Domain\USER

    - by Jalvemo
    in my asp.net MVC project i have an database connection with connectionstring: Data Source=.;Initial Catalog=dbname;Integrated Security=True All users can execute Stored Procedures on that connection and i want to log those users. so after each execution I store "User.Identity.Name" to another database. This work great on my development machine but after deployment, to access the site i have to go through a VPN-connention and then remote desktop to the same server that the IIS is running on and use a web-browser there. Then i get User.Identity.Name: "NT AUTHORITY\NETWORK SERVICE". i would expect it to be the credentials i entered in remote desktop that have access to the database. any idea how i can get this to work? iis6 authentication: "windows authentication: enabled" web.config:

  • Handling selection and deselection of objects in a user interface

    - by Dennis
    I'm writing a small audio application (in Silverlight, but that's not really relevant I suppose), and I'm a struggling with a problem I've faced before and never solved properly. This time I want to get it right. In the application there is one Arrangement control, which contains several Track controls, and every Track can contain AudioObject controls (these are all custom user controls). The user needs to be able to select audio objects, and when these objects are selected they are rendered differently. I can make this happen by hooking into the MouseDown event of the AudioObject control and setting state accordingly. So far so good, but when an audio object is selected, all other audio objects need to be deselected (well, unless the user holds the shift key). Audio objects don't know about other audio objects though, so they have no way to tell the rest to deselect themselves. Now if I would approach this problem like I did the last time I would pass a reference to the Arrangement control in the constructor of the AudioObject control and give the Arrangement control a DeselectAll() method or something like that, which would tell all Track controls to deselect all their AudioObject controls. This feels wrong, and if I apply this strategy to similar issues I'm afraid I will soon end up with every object having a reference to every other object, creating one big tightly coupled mess. It feels like opening the floodgates for poorly designed code. Is there a better way to handle this?

  • Growing user control not updating

    - by user328259
    I am developing in C# and .Net 2.0. I have a user control that draws cells (columnar) depending upon the maximum number of cells. There are some drawing routines that generate the necessary cells. There is a property NumberOfCells that adjust the height of this control; CELLHEIGHT_CONSTANT * NumberOfCells. The OnPaint() method is overridden (code that draws the Number of cells). There is another user control that contains a panel which contains the userControl1 from above. There is a property NumberCells that changes userControl1's NumberOfCells. UserControl2 is then placed on a windows form. On that form there is a NumericUpDown control (only increments from 1). When the user increments by 1, I adjust the VerticalScroll.Maximum by 1 as well. Everything works well and good BUT when I increment once, the panel updates fine (inserts a vertical scrolll when necessary) but cells are not being added! I've tried Invalidating on userControl2 AND on the form but nothing seems to draw the newly added cells. Any assistance is appreciated. Thank you in advance. Lawrence

  • Can you make a Windows network default user profile NOT apply to a certain operating system?

    - by Jordan Weinstein
    I would like to create a network Default User account for Windows 7 only. This is on a Windows 2003 domain with servers from Windows 2000 to 2008 R2 and Windows XP on workstation side. We're about to do a full migration to Windows 7 and I'd like to start using the network default user profile functionality as we're not migrating user profiles over. Want everyone to start clean. I followed the simple steps from this page: http://support.microsoft.com/kb/973289 under the heading: "How to turn the default user profile into a network default user profile in Windows 7 and in Windows Server 2008 R2" but the problem is that profile would then apply to a new user\admin logging into a 2008 server. That's no good. Anyone have any ideas on how to limit what actually uses that network profile? I was thinking about setting deny permissions for all my admin\service accounts on that "\\dcserver\netlogon\Default User.v2" folder but then it might be timing out and cause other problems. Haven't tried yet as that seems like a bad way of making this work.

  • Partner outreach on the Oracle Fusion Applications user experience begins

    - by mvaughan
    by Misha Vaughan, Architect, Applications User Experience I have been asked the question repeatedly since about December of last year: “What is the Applications User Experience group doing about partner outreach?”  My answer, at the time, was: “We are thinking about it.”  My colleagues and I were really thinking about the content or tools that the Applications UX group should be developing. What would be valuable to our partners? What will actually help grow their applications business, and fits within the applications user experience charter?In the video above, you’ll hear Jeremy Ashley, vice president of the Applications User Experience team, talk about two fundamental initiatives that our group is working on now that speaks straight to partners.  Special thanks to Joel Borellis, Kelley Greenly, and Steve Hoodmaker for helping to make this video happen so flawlessly. Steve was responsible for pulling together a day of Oracle Fusion Applications-oriented content, including David Bowin, Director, Fusion Applications Strategy, on some of the basic benefits of Oracle Fusion Applications.  Joel Borellis, Group Vice President, Partner Enablement, and David Bowin in the Oracle Studios.Nigel King, Vice President Applications Functional Architecture, was also on the list, talking about co-existence opportunities with Oracle Fusion Applications.Me and Nigel King, just before his interview with Joel. Fusion Applications User Experience 101: Basic education  Oracle has invested an enormous amount of intellectual and developmental effort in the Oracle Fusion Applications user experience. Find out more about that at the Oracle Partner Network Fusion Learning Center (Oracle ID required). What you’ll learn will help you uncover how, exactly, Oracle made Fusion General Ledger “sexy,” and that’s a direct quote from Oracle Ace Director Debra Lilley, of Fujitsu. In addition, select Applications User Experience staff members, as well as our own Fusion User Experience Advocates,  can provide a briefing to our partners on Oracle’s investment in the Oracle Fusion Applications user experience. Looking forward: Taking the best of the Fusion Applications UX to your customersBeyond a basic orientation to one of the key differentiators for Oracle Fusion Applications, we are also working on partner-oriented training.A question we are often getting right now is: “How do I help customers build applications that look like Fusion?” We also hear: “How do I help customers build applications that take advantage of the next-generation design work done in Fusion?”Our answer to this is training and a tool – our user experience design patterns – these are a set of user experience best-practices. Design patterns are re-usable, usability-tested, user experience components that make creating Fusion Applications-like experiences straightforward.  It means partners can leverage Oracle’s investment, but also gain an advantage by not wasting time solving a problem we’ve already solved. Their developers can focus on helping customers tackle the harder development challenges. Ultan O’Broin, an Apps UX team member,  and I are working with Kevin Li and Chris Venezia of the Oracle Platform Technology Services team, as well as Grant Ronald in Oracle ADF, to bring you some of the best “how-to” UX training, customized for your local area. Our first workshop will be in EMEA. Stay tuned for an assessment and feedback from the event.
