  • Help creating a ColumnName Convention using FluentNHibernate

    - by Rafael E. Belliard
    I've been trying to specify a custom naming convention for my database table columns. So far, I have been able to setup a convention for the table's name, but not the actual columns. I've seen a few guides on the internet, but they're not working using the latest Fluent NHibernate (1.0.0 RTM). public class CamelCaseSplitNamingConvention : IClassConvention, IComponentConvention { public void Apply(IClassInstance instance) { instance.Table(instance.EntityType.Name.ChangeCamelCaseToUnderscore()); } public void Apply(IComponentInstance instance) { // is this the correct call for columns? If not, which one? } } Please help.

  • PHP regex help -- reverse search?

    - by Ian Silber
    So, I have a regex that searches for HTML tags and modifies them slightly. It's working great, but I need to do something special with the last closing HTML tag I find. Not sure of the best way to do this. I'm thinking some sort of reverse reg ex, but haven't found a way to do that. Here's my code so far: $html = "<div id="test"><p style="hello_world">This is a test.</p></div>"; $pattern = array('/<([A-Z][A-Z0-9]*)(\b[^>]*)>/i'); $replace = array('<tag>'); $html = preg_replace($pattern,$replace,$html); // Outputs: <tag><tag>This is a test</p></div> I'd like to replace the last occurance of "" with something special, say for example, "". Any ideas?

  • Help me understand Rails eager loading

    - by aaronrussell
    I'm a little confused as to the mechanics of eager loading in active record. Lets say a Book model has many Pages and I fetch a book using this query: @book = Book.find book_id, :include => :pages Now this where I'm confused. My understanding is that @book.pages is already loaded and won't execute another query. But suppose I want to find a specific page, what would I do? @book.pages.find page_id # OR... @book.pages.to_ary.find{|p| p.id == page_id} Am I right in thinking that the first example will execute another query, and therefore making the eager loading pointless, or is active record clever enough to know that it doesn't need to do another query? Also, my second question, is there an argument that in some cases eager loading is more intensive on the database and sometimes multiple small queries will be more efficient that a single large query? Thanks for your thoughts.

  • Dynamic table design (common lookup table), need a nice query to get the values

    - by Swoosh
    sql2005 This is my simplified example: (in reality there are 40+ tables in here, I only showed 2) I got a table called tb_modules, with 3 columns (id, description, tablename as varchar): 1, UserType, tb_usertype 2, Religion, tb_religion (Last column is actually the name of a different table) I got an other table that looks like this: tb_value (columns:id, tb_modules_ID, usertype_OR_religion_ID) values: 1111, 1, 45 1112, 1, 55 1113, 2, 123 1114, 2, 234 so, I mean 45, 55, 123, 234 are usertype OR religion ID's (45, 55 usertype, 123, 234 religion ID`s) Don't judge, I didn't design the database Question How can I make a select, showing * from tb_value, plus one column That one column would be TITLE from the tb_usertype or RELIGIONNAME from the tb_religion table I would like to make a general thing. Was thinking initially about maybe a SQL function that returns a string, but I think I would need dynamic SQL, which is not ok in a function. Anyone a better idea ?

    Hello, I have this jquery code: $(".button-banc").hover(function() { $(".button-banc img") .animate({ top: "-21px" }, 200).animate({ top: "-17px" }, 200) // first jump .animate({ top: "-19px" }, 100).animate({ top: "-17px" }, 100) // second jump .animate({ top: "-18px" }, 100).animate({ top: "-17px" }, 100); // the last jump }); The effect I want is: when you pass the mouse over an image this image should jump a bit. The problem is that I got "some" images with the class "button-banc" and I want this behaive: When you pass the mouse over, "only the actual image" should jump. The problem is that with the code I posted, every image jumps. How can I achieve this, please help; I want to make a generic way, so that if I add images with the class, they also behaive like that.

  • Help Auditing in Oracle

    - by enrique
    Hello everybody I need some help in auditing in Oracle. We have a database with many tables and we want to be able to audit every change made to any table in any field. So the things we want to have in this audit are: user who modified time of change occurred old value and new value so we started creating the trigger which was supposed to perform the audit for any table but then had issues... As I mentioned before we have so many tables and we cannot go creating a trigger per each table. So the idea is creating a master trigger that can behaves dynamically for any table that fires the trigger. I was trying to do it but no lucky at all....it seems that Oracle restricts the trigger environment just for a table which is declared by code and not dynamically like we want to do. Do you have any idea on how to do this or any other advice for solving this issue? thanks in advance.

  • Would Mercurial help me work from 2 PCs?

    - by rikh
    I currently use Perforce for source control, but want to start working on the code from 2 different PCs at the same time (desktop and laptop). The laptop would not be able to access the perforce server very often, which makes Perforce a poor choice in this setup. Distributed source control tools like Mercurial seem better suited to the task, but I am still not clear if this would work or not. Does anyone have any experience of using Mercurial to work on 2 machines at once (eg desktop in the week, laptop in evening and weekends). Does it help, or is it still a pain the butt keeping everything in sync and knowing what is going on.

    - by Shaza
    Hey, I have a problem in choosing the right method to accomplish my goal. I'm working on Algorithms teaching system, I'm using C#. I need to divide my algorithm into steps, each step will contain a recursion. I have to stop execution after each step, user can then move to the next step(next recursion) using a button in my GUI. After searching, threads was the right choice, but I found several methods: (Thread.sleep/interrupt): didn't work, my GUI freezed !! (Suspend/Resume): I've read that it's a bad idea to use. (Waithandles): still reading about them. (Monitor wait/resume). I don't have much time to try and read all previous methods, please help me in choosing the best method that fits my system.Any suggestions are extremal welcomed.

  • tsql proc logic help

    - by bacis09
    I am weak in SQL and need some help working through some logic with my proc. Three pieces: store procedure, table1, table2 Table 1 stores most recent data for specific IDs Customer_id status_dte status_cde app_dte 001 2010-04-19 Y 2010-04-19 Table 2 stores history of data for specific customer IDs: For example: Log_id customer_Id status_dte status_cde 01 001 2010-04-20 N 02 001 2010-04-19 Y 03 001 2010-04-19 N 04 001 2010-04-19 Y The stored proecure currently throws an error if the status date from table1 is < than app_date in table1. If @status_dte < app_date Error Note: @status_dte is a variable stored as the status_dte from table1 However, I want it to throw an error when the EARLIEST status_dte from table 2 with a status_cde of 'Y' is less than the app_dte column in table 1. Keep in mind that this earliest date is not stored anywhere, the history of data changes per customer. Another customer might have the following history. Log_id customer_Id status_dte status_cde 01 002 2010-04-20 N 02 002 2010-04-18 N 03 002 2010-04-19 Y 04 002 2010-04-19 Y Any ideas on how I can approach this?

  • jQuery Cookie Help

    - by Bruno
    Hi there.. So I have never attempted to use a cookie and was wondering if someone could possibly help me with some functionality I am trying to achieve.. Essentially I have a jQuery function that is fired when a user visits a webpage. What I would like to do is make it to where that animation only plays once.. Possibly leveraging some cookie that would tell it not to play again for x amount of days. I noticed that alot of people having questions about cookies and jQuery have been mentioned the following cookie plugin, but I dont even really know how to leverage it. Any ideas? Right now the animation is: $('#header, #footer, #secondary-column').fadeTo(600, 1); I would assume that if I could set a cookie to tell it the following: $('#header, #footer, #secondary-column').fadeTo(0, 1);

  • help understanding the concept of javascript callbacks with node.js, especially in loops

    - by Mr JSON
    hi I am just starting with node.js. I have done a little ajax stuff but nothing too complicated so callbacks are still kind of over my head. I looked at async but all I need is to run a few functions sequentially. I basically have something that pulls some json from an api, creates a new one and then does something with that. obviously i can't just run it because it runs everything at once and has an empty json. mostly they have to go sequentially but if while pulling a json from the api it can pull other json while it's waiting that is fine. I just got confused when putting the callback in a loop. what do I do with the index? i think i have seen some places that use callback inside the loop as kind of a recusive function and don't use for loops at all. simple examples would help alot thanks!

  • PyQt4 Need to move DLLs to package root

    - by Xavier
    Hi Guys, I've used the new installers from http://www.riverbankcomputing.co.uk/software/pyqt/download for Python 2.6 x86_64 and I've a small problem importing PyQt4 in one particular application. Here's the traceback: # ERROR : Traceback (most recent call last): # File "<Script Block >", line 2, in <module> # from PyQt4 import QtCore # ImportError: DLL load failed: The specified procedure could not be found. # - [line 2] This might look familiar. Fun thing is that in a previous version of the 3d software it does work (and from a standard command line), but not in the new software version. I inspected the sys.path (within the app) in order to see if this path was there: C:\Python26\Lib\site-packages\PyQt4\bin In both application this path is present. Finally managed to make it works by copying the DLLs from C:\Python26\Lib\site-packages\PyQt4\bin to C:\Python26\Lib\site-packages\PyQt4 Is there any known reason for this? I've a hard time debugging this thing further (making sure everything is 64 bit, path are correct, etc) Thanks for your help
