• Multiple controllers with a single model

  - by Eric K

  I'm setting up a directory application for which I need to have two separate interfaces for the same Users table. Basically, administrators use the Users controller and views to list, edit, and add users, while non-admins need a separate interface which lists users in a completely different manner. To do this, would I be able to just set up another controller with different views but which accesses the Users model? Sorry if this is a simple question, but I've had a hard time finding how to do this.

• visual tool to resolve conflicts merged into a single file

  - by Yehosef

  I did a git merge and ended up with a file like that looks like this: class member extends item{ /********CONSTANTS**********/ const is_flaggable = true; const is_commentable = false; const is_ratable = false; const table = 'member'; <<<<<<< HEAD const table_about = 'mem_about' ; const table_to_about = 'mem_to_about' ; const table_hobbies = 'mem_to_hobby'; ======= const table_friendship = 'friendship'; const table_about = 'mem_about' ; const table_to_about = 'mem_to_about' ; const table_hobbies = 'mem_to_hobby'; const table_friendship_id = 3; >>>>>>> my-copy In this file there are many blocks like this. Is there a visual tool to help me look at this file and pick and choose the changes I want? Most of the diff tools I found are for looking at two files.

• How to compare 2 pdf files using command line or any tool

  - by Darzen

  I have to compare 2 pdf files and check if they are same or different. I have tried my luck with WinMerge and Beyond compare. however they dont solve my issue. The issue is that there are 2 files which are exactly same except for the time in which they were saved. I have a piece of code that embeds the time of saving into the file. but i am not supposed to do any modifications to the code I have. Hence the above mentioned tools will say that the files dont match and There is just one difference, that is timestamp. Can anyone suggest me a way to handle this. Please. Thanks

• Injecting single-use object into class

  - by moteutsch

  I have the following code: <?php class X { public function do($url) { $httpRequest = new \HttpRequest\Curl($url, $this->getOptions()); $httpRequest->fire(); // etc. } // ... } In order to be able to unit test this class, I'd like to inject a mocked HttpRequest class. One way to do this would be as follows: <?php class X { private $httpRequestClass; public function __construct($httpRequestClass = '\HttpRequest\Curl') { $this->httpRequestClass = $httpRequestClass; } public function do($url) { $httpRequest = new $this->httpRequestClass($url, $this->getOptions()); $httpRequest->fire(); // etc. } // ... } But this doesn't seem right. Any other ideas?

• creating a static vb.net "app" that consist of a single picture

  - by michael

  I need to create a vb.net program that consists of a unmovable, always on top bitmap, with no menu bar or anything, and does not show up in the task bar as program. It needs to always start in the same place. Essentially I need to mask a part of the screen by using a bitmap that blends into the scenery. I am not sure which properties I need to tweak to achieve all of this.

• Application frame leaves blank line at the top

  - by iFloh

  Any clues why my programmatically defined UIScrollView (using the application frame) always leaves an empty space at the top (below the navigationBar) of 20 pixels. How can I close that? UIScrollView *vScrollView = [[UIScrollView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]]; vScrollView.backgroundColor = [UIColor redColor]; How do I need to call the application frame size to avoid that gap?

• Django: Converting an entire Model into a single dictionary

  - by LarrikJ

  Is there a good way in Django to convert an entire model to a dictionary? I mean, like this: class DictModel(models.Model): key = models.CharField(20) value = models.CharField(200) DictModel.objects.all().to_dict() ... with the result being a dictionary with the key/value pairs made up of records in the Model? Has anyone else seen this as being useful for them? Thanks. Update I just wanted to add is that my ultimate goal is to be able to do a simple variable lookup inside a Template. Something like: {{ DictModel.exampleKey }} With a result of DictModel.objects.get(key__exact=exampleKey).value Overall, though, you guys have really surprised me with how helpful allof your responses are, and how different the ways to approach it can be. Thanks a lot.

• Can single-buffer blocking WSASend deliver partial data?

  - by CodeAngry

  I've pretty much always used send() with sockets and now I'm moving onto the WSA functions. With send(), I have a sendall() helper that ensured all data is delivered even if it didn't happen in one try and a partial send occurred on first call. So, instead of learning the hard way or over-complicating code when I don't have to, decided to ask you: Can a blocking WSASend() send partial data or does it send everything before it returns or fails? Or should I check the bytes sent vs. expected to send and keep at it until everything is delivered? ANSWER: Overlapped WSASend() does not send partial data but if it does, it means the connection has terminated. I've never encountered the case yet.

• Rails - single ID for multiple models

  - by user352351

  I'm building an app which will allow a user to scan the barcode on a 'shelf', 'box' or 'product' which will then bring up that particular item or all the associated items. As these are all separate models with their own ID's, I need a global ID table. I was thinking of a polymorphic table called 'barcodes' barcodes id barcode_number barcodable Is there an easy way to do this? Or is polymorphic the best way?

• Considerations when porting a MS VC++ program (single machine) to a rocks cluster

  - by Mel

  I am trying to port a MS VC++ program to run on a rocks cluster! I am not very good with linux but I am eager to learn and I imagine porting it wouldn't be an impossible task for me. However, I do not understand how to take advantage of the cluster nodes. because it seems that the code execute only runs on the front end server (obviously). I have read a little about MPI and its seems like I should use MPI to comminicate between nodes. The program is currently written such that I have a main thread that synchronizes all worker threads. The main thread also recieves commands to manipulate the simulation or query its state. If the simulation is properly setup, communication between executing threads can be significantly minimized. What I don't understand is how do I start the process on the compute nodes and how do I handle failures in nodes? And maybe there should be other things I should also consider when porting my program to run in a cluster?

• Ant command line arguments

  - by js7354

  Program works fine when run with eclipse run configurations, but when run with ant, it is unable to parse int from args[0], which I do not understand. Full code is available here https://gist.github.com/4108950/e984a581d5e9de889eaf0c8faf0e57752e825a97 I believe it has something to do with ant, target name="run" description="run the project"> java dir="${build.dir}" classname="BinarySearchTree" fork="yes"> <arg value="6 in.txt"/> /java> /target> the arg value will be changed via the -D flag, as in ant -Dargs="6 testData1.txt" run. Any help would be much appreciated, it is very frustrating.

• tables wrapping to next line when width 100%

  - by jmo

  I'm encountering some weirdness with tables in css. The layout is fairly simple, a fixed-width nav bar on the left and the content on the right. When the content includes a table with a width of 100% the table ends up getting pushed down until it has room to take up the full width of the screen (instead of just the area to the right of the nav bar). If I remove the width=100% from the table's css, then it looks fine, but obviously the table doesn't grow to fill the space of the div. The problem is that i want the table to grow and shrink with the window but still stay in the bounds of its div. Thanks. Here's a simple example: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <title>Test</title> <style type="text/css"> #content { padding-right:20px; background:white; overflow:hidden; margin:20px; } #content .column { position:relative; padding-bottom: 20010px; margin-bottom: -20000px; } #center { width:100%; padding-top:15px; } body { min-width:700px; } #left { width: 330px; padding: 0 10px; padding-top:10px; float:left; } .tableData { width:100%; } </style> </head> <body> <div id="content"> <div class="column" id="left"> <div> Some text goes in here<br/> some more text<br/> some more text<br/> some more text<br/> some more text<br/> some more text<br/> </div> </div> <div class="column" id="center"> Some text at the top; <hr/> <table class="tableData"> <thead> <tr><th>A</th><th>B</th><th>C</th></tr> </thead> <tbody> <tr> <td>A1 A1 A1 A1</td> <td>B1 B1 B1 B1</td> <td>C1 C1 C1 C1 C</td> </tr> <tr> <td>A2 A2 A2 A2 </td> <td>B2 B2 B2 B2 </td> <td>C2 C2 C2 C2</td> </tr> <tr> <td>A3 A3 A3 A3 A3 </td> <td>B3 B3 B3 B3 B3 </td> <td>C3 C3 C3 C3 C3</td> </tr> <tr> <td>A4 A4 A4 A4 A4</td> <td>B4 B4 B4 B4 B4</td> <td>C4 C4 C4 C4 C4</td> </tr> </tbody> </table> </div> </div> </body> </html>

• How to integrate technical line/functional manager into Scrum team?

  - by thegreendroid

  We have recently had a new line manager start who is managing our Scrum team. He is immensely experienced in our field but is relatively inexperienced at Agile/Scrum. He has extensive technical expertise in embedded software (the team's domain) that would go to waste if not utilised properly. However, the team is wary of making a line manager part of the Scrum team. The general consensus is that the line manager should not be part of the Scrum team at all. There are a number of issues that may crop up, e.g. the team may start "reporting" to the manager (i.e. a daily status update!), the manager may start to micro-manage team members etc etc. As it currently stands, he has already said that he feels like an outsider within the team. We really want to make use of his technical skills, we'd be foolish if we didn't because we are a relatively inexperienced and young team of twenty somethings. What would be the best approach to integrate a senior "technical" line manager in a Scrum team and make him feel like he is part of the team?

• How do I remove a malformed line from my sources.list?

  - by eminencejae

  I have unistalled and reinstalled the Ubuntu Software Center as per info I found in a similar thread and I got the same response about line 91 or something like that. I just tried to upload a screen shot but since I'm new it won't allow me to. I also can not figure out how to cut and paste anything so I have to hand type what the error screen says, both when I attempt to open the software center and nothing happens, when I try to enter commands into the terminal to uninstall, reinstall, whatever I get the same following: COULD NOT INTITIALIZE THE PACKAGE INFORMATION An unresolvable problem occured while initializing the package information Please report t:his bug against the 'update-manager' package and include the following error message: 'E: Malformed line 91 in source list/etc/apt/sources.list (dist parse) E: The list of sources could not be read., E: The package list of status file could not be parsed or opened. How do I report bugs? What can be done about this. I have searched and everything everyone says to do leads me back to the same line error message. So, I don't know how to get to line 91 in the source list; to tell you what it says. Sorry, I'm really new to this. That is what I need is to find out how to get there and fix what it says. I would really like to NOT have to re partition my hard drive and start from scratch, so I'm really looking forward to getting this problem solved. I need to be able to install new software.
