  • ordering a collection by an association's property

    - by neiled
    class Person belongs_to :team class Status #has last_updated property class Team has_many :members, :class => "Person" Ok, so I have a Team class which has many People in it and each of those people has a status and each status has a last_updated property. I'm currently rendering a partial with a collection similar to: =render :partial => "user", :collection => current_user.team.members Now how do I go about sorting the collection by the last_updated property of the Status class? Thanks in advance! p.s. I've just written the ruby code from memory, it's just an example, it's not meant to compile but I hope you get the idea!

  • Basic CSS: having unordered list extend beyond container div?

    - by Tony
    Hi. It's been a bit since I've gotten really into CSS work, I'm trying to make a simple layout with a menubar. The idea is to have a container holding everything in the center of the screen and have a menubar (unordered inline list) that runs the full length of the screen but the list items to be contained in the container. See this pic for a visual example ps. I know this isn't true "programming", but this seemed like the most appropriate place to post this question. Let me know if there's a better /r/ for this to go.

  • Writing at the end of file

    - by user342534
    Hi, I'm working on a system that requires high file I/O performance (with C#). Basically, I'm filling up large files (~100MB) from the start of the file until the end of the file. Every ~5 seconds I'm adding ~5MB to the file (sequentially from the start of the file), on every bulk I'm flushing the stream. Every few minutes I need to update a structure which I write at the end of the file (some kind of metadata). When flushing each one of the bulks I have no performance issue. However, when updating the metadata at the end of the file I get really low performance. My guess is that when creating the file (which also should be done extra fast), the file doesn't really allocates the entire 100MB on the disk and when I flush the metadata it must allocates all space until the end of file. Guys/Girls, any Idea how I can overcome this problem? Thanks a lot!

  • MySQL Database || Tables Issue

    - by user1780103
    I'm trying to write up a script where the user is able to purchase an amount of points for dollars. I want the transaction to be inserted into MySQL. I keep facing a: "Column count doesn't match value count at row 1" error. And I have no idea what I'm doing wrong. I have written up this: mysql_query("INSERT INTO paypal_donations VALUES (NULL, ".$account_id.", ".$char_id.", ".$price.", ".$dp.", NOW(), NOW(), 'Started', 0, 0, '', '');") or die(mysql_error()); But I don't know what to execute in MySQL, since I've never worked with it before. Could anyone write up a quick script that I can insert into MySQL for it to work.

  • C++ Char without Limit

    - by Lienau
    I'm pretty well versed in C#, but I decided it would be a good idea to learn C++ as well. The only thing I can't figure out is chars. I know you can use the string lib but I also want to figure out chars. I know you can set a char with a limit like this: #include <iostream> using namespace std; int main() { char c[128] = "limited to 128"; cout << c << endl; system("pause"); return 0; } But how would I make a char without a limit? I've seen chars with * but I though that was for pointers. Any help is greatly appreciated.

  • jQuery won't parse xml with nodes called option

    - by user170902
    hi all, I'm using jQuery to parse some XML, like so: function enumOptions(xml) { $(xml).find("animal").each(function(){ alert($(this).text()); }); } enumOptions("<root><animal>cow</animal><animal>squirrel</animal></root>"); This works great. However if I try and look for nodes called "option" then it doesn't work: function enumOptions(xml) { $(xml).find("option").each(function(){ alert($(this).text()); }); } enumOptions("<root><option>cow</option><option>squirrel</option></root>"); There's no error, just nothing gets alerted, as if the find isn't finding anything. It only does it for nodes called option everything else I tested works ok! I'm using the current version of jQuery - 1.4.2. Anyone any idea? TIA. bg

  • Any ORMs that easily support access to raw table schema?

    - by fizil
    I work with a ASP.NET UI framework that pulls fields for a particular screen off a database. These fields can be associated with particular data fields in another database for binding. The idea with this setup is that if a client needs a new column on a table, they can easily add it, and create a UI field that binds to it without any sort of application restart or recompile. The problem I've always had with this is that it has meant I'm always having to work with untyped datasets in my code. Are there any ORM libraries for .NET out there that could easily accommodate the requirement of being able to access arbitrary columns in the table schema over and above ones mapped to strongly typed fields?

  • Mercurial adding new file gives no match found error

    - by Ivo
    I have a strange problem with updating Mercurial. Everytime when I add a file to my repository and then update another location of the repository (for example with in CI process), the error "no match found" occures.

  • Process locks a folder

    - by Vad
    Have pretty odd situation. There are 2 applications: 1) C:\MyFolder1\First.exe 2) C:\MyFolder2\Second.exe First.exe runs Second.exe and quits. Process.Start(@"C:\MyFolder2\Second.exe"); // And exit. Seconds.exe waits a few seconds and tries to remove "C:\MyFolder1\" folder. // Wait for 5 seconds - First.exe terminated by that time for 100% Directory.Delete(@"C:\MyFolder1\", true); Action fails with “The process cannot access the file ‘C:\MyFolder1\’ because it is being used by another process.” It's able to remove the First.exe file (actually all files in the folder), but not the folder itself. Does anybody have an idea why the folder is locked by the second process?

  • ActiveRecord and transactionsin between `before_save` and `save`

    - by JP
    I have some logic in before_save whereby (only) when some conditions are met I let the new row be created with special_number equal to the maximum special_number in the database + 1. (If the conditions aren't met then I do something different, so I can't use auto-increments) My worry is that two threads acting on this database at once might pick the same special_number if the second is executed while the first is saving. Is there way to lock the database between before_save and finishing the save, but only in some cases? I know all saves are sent in transactions, will this do the job for me? def before_save if things_are_just_right # -- Issue some kind of lock? # -- self.lock? I have no idea # Pick new special_number new_special = self.class.maximum('special_number') + 1 write_attribute('special_number',new_special) else # No need to lock in this case write_attribute('special_number',some_other_number) end end

  • Is there a way to embed an mp3 player in a website that isn't flash based (so that the website is iP

    - by hartleybrody
    I did a lot of searching for what I thought would be a pretty common question, but I came up with nothing. If there is another thread with a similar topic, please let me know. Basically, I'm looking for a way to have an .mp3 file play in a website without relying on a flash-based player. I've searched w3 schools and every forum I can think of, but every media player I've found so far has been some sort of proprietary flash player. Doesn't HTML support some sort of native player? I've found some that rely on Windows Media Player which is close, but I want the player to work on an iPhone and something tells me WMP won't get that done... PS, as I'm thinking more about this this idea just popped into my head: a javascipt player and inside the <noscript> tag, put a flash player? I'm running a music blog (@ http://www.freshoncampus.com) so the less code per post, the better...

  • Java - Count words in two documents

    - by user552961
    Good Morning - it is school assignment, I am not asking for any source code (if you can provide any pesudo code it would be awesome). Here is the problem :( I have to create a term frequency table. It is not pure TF, I just need to count the words and write down. I know basic steps to do it 1 - extract all terms (I can do it with file reader) 2 - remove repeating terms (I can do it with TreeMap) The output of 2nd step would be Niga, ponga, dinga, bitlo, etc. 3 - Now I have to see if there is any word in current file from above terms or not, if yes then I will count. Now this is my problem, I stucked on step 3 :( I have some idea how to count words with TreeMap (treemap.containskey etc.) but it would be global count not local count for each file :( Any pseudo code?

  • Retain Site Background and Switch Pages?

    - by yar
    I was about to redo a Rails site today using AJAX so that the background could remain in place. Then I thought, "that would be exactly like using frames," and then I thought about SEO consequences and I dropped the idea entirely and took a look around the Web. It turns out that few sites -- except for Google itself, which has the link bar at the top -- are doing this. It doesn't look impossible to do, but it's not exactly easy. Aside from Ajaxing, you have to think about updating the query-string and having SEO-friendly links (that actually don't work, but rather make background requests via Javascript). Will any of the new technologies -- HTML5, perhaps -- solve this problem and allow us to have a Web with background colors (and other static elements) that do not disappear momentarily between page refreshes? On the other hand, why are few devs doing this with current technologies? Is it just not a big deal, too complicated to implement, or....?

  • what is the purpose of numeric/boolean/string objects as opposed to primitive values?

    - by zespri
    In javascript you can call a function as a function or as a constructor. For example you can do : myObject = new Number(13); myPrimitiveValue = Number(13); or simply myPrimitiveValue = 13; I understand the difference between the results. Can you explain me under which reasonable circumstances creating a number, a boolean or a string as an object is desirable? For example, ability to set new properties (this is something you can do on objects but can't really do on primitive values) is almost always a bad idea for objects containing number/boolean/string. Why would I want a numeric/boolean/string object?

  • Are there Vi/Vim users who aren't touch typists?

    - by michael
    I'm trying to write a Vim tutorial and I'd like to start by dismissing a few misconceptions, as well as giving some recommendations. I don't know if I should dismiss touch-typing as a misconception, or include it as a recommended prerequisite. At the time I learned the editor, I had already been touch typing for a couple of years, so I have absolutely no idea what would be the experience of a two-fingered typist in Vim. Are you a vim two-fingered typist? what has your experience been like?

  • Pointer aliasing- in C++0x

    - by DeadMG
    I'm thinking about (just as an idea) disjointed pointer aliasing in C++0x. I was thinking about seeing if it could be implemented similarly to const correctness- that is, enforced by the compiler. What would be the requirements for such a thing? As this is more of a thought experiment, I'm perfectly happy to look at solutions that destroy legacy code or redefine half the language and that kind of thing. What I'd really rather not do is have, say, restrict from C99 where the programmer just promises it. It should be enforced.

  • String as \x03\x00\x00\x00 to integer

    - by marta
    Helo: I have a question, that I solved in c, but now I want to do it in hava: I have a String like: '\x03\x00\x00\x00' This is representing an hexadecimal value of a integer. I transform to 0x03\0x00... And now I want to obtain the integer, but I don't know how to do it in java could someone give me some idea ? Thanks in advance (Is it some way to use this format ('\x03\x00\x00\x00' ) directly without use byte[] arrays? and in C can I use this format directly to build a integer (int)?)

  • When is it good to use FTP?

    - by Tom Duckering
    In my experience I see a lot of architecture diagrams which make extensive use of FTP as a medium for linking architectural components. As someone who doesn't make architectural decisions but tends to look at architecture diagrams could anyone explain what the value is of using FTP, where it's appropriate and when transferring data as files is a good idea. I get that there are often legacy systems that just need to work that way - although any historical insight would be interesting too I can see the attraction in transferring files (especially if that's what needs to be transferred) because of the simplicity and familiarity and wonder if the reasoning goes beyond this.

  • Continue Drupal processing after page send.

    - by David
    I need to do some additional processing after a Drupal page has been sent. I know I could fire a background shell command, but I need the current Drupal execution context to be maintained. I've spent a lot of time looking, but I can't find any documentation in this regard. This is surprising because it must surely be a common requirement. The only real idea I have is to fire up Drupal (again) via a shell command (exec, etc) and supply it with a pseudo path which would invoke the continued processing. But this seems unnecessarily complex/wasteful. Any pointers greatly appreciated, tks.

  • Use AJAX to check for a new message

    - by Luke
    Quite simply, I need to alert the end user when they have a new private message. From a combination of research and other opinion, I realise I need to use AJAX for this. The mysql query would be SELECT id FROM tbl_messages WHERE to_viewed = 1 So when someone sends a message, I want an alert to popup on the screen to inform the user without a page reload. I have absolutely no idea what I am doing, but know what I want. Really need help with this, AJAX is definitely something I want to improve as it opens up greater possibilities! Thanks
