  • perl - converting a date into a string

    - by Jason
    I need to convert a date to a string, the date is entered as 07/04/2010 and should then read July 4th 2010. It should also be able to be entered using singe digits instead of double (7 instead of 07, and it needs to add the 20 to the year if the user enters only /10) This is what I have so far - #!/usr/bin/perl use CGI qw(:standard); use strict; #declare variables my ($date, $month, $day, $year); my @months = ("January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"); #assign input item to variable $date = param('Date'); #break date apart $date =~ /([0-9]{1,2})\/([0-9]{1,2})\/([0-9]{2,2}|20[0-9]{2,2})/; $month = $1; $day = $2; $year = $3; unless($year =~ /20[0-9]{2,2}/){ $year = "20".$year; } $date = $months[int($1)]." ".$day.", ".$year; #display date print "<HTML><HEAD><TITLE>The Date</TITLE></HEAD>\n"; print "<BODY>\n"; print "The date is: $date\n"; print "</BODY></HTML>\n"; However I keep getting errors Use of uninitialized value in pattern match (m//) at c08ex6.cgi line 14.

  • Ruby-on-Rails equivalent to ORM Designer for Symfony?

    - by fayer
    In Symfony i just have to create models with ORM Designer and export it to symfony as a schema.yml and then use a symfony command to create tables, models and forms. I wonder if there is an equivalent to the RoR so that you dont have to create models manually by hand? It saves a lot of time using GUI for this kind of tasks and it is less error-prone. thanks

  • Generate A Simple Read-Only DAL?

    - by David
    I've been looking around for a simple solution to this, trying my best to lean towards something like NHibernate, but so far everything I've found seems to be trying to solve a slightly different problem. Here's what I'm looking at in my current project: We have an IBM iSeries database as a primary repository for a third party software suite used for our core business (a financial institution). Part of what my team does is write applications that report on or key off of a lot of this data in some way. In the past, we've been manually creating ADO .NET connections (we're using .NET 3.5 and Visual Studio 2008, by the way) and manually writing queries, etc. Moving forward, I'd like to simplify the process of getting data from there for the development team. Rather than creating connections and queries and all that each time, I'd much rather a developer be able to simply do something like this: var something = (from t in TableName select t); And, ideally, they'd just get some IQueryable or IEnumerable of generated entities. This would be done inside a new domain core that I'm building where these entities would live and the applications would interface with it through a request/response service layer. A few things to note are: The entities that correspond to the database tables should be generated once and we'd prefer to manually keep them updated over time. That is, if columns/tables are added to the database then we shouldn't have to do anything. (If some are deleted, of course, it will break, but that's fine.) But if we need to use a new column, we should be able to just add it to the necessary class(es) without having to re-gen the whole thing. The whole thing should be SELECT-only. We're not doing a full DAL here because we don't want to be able to break anything in the database (even accidentally). We don't need any kind of mapping between our domain objects and the generated entity types. The domain barely covers a fraction of the data that's in there, most of it we'll never need, and we would rather just create re-usable maps manually over time. I already have a logical separation for the DAL where my "repository" classes return domain objects, I'm just looking for a better alternative to manual ADO to be used inside the repository classes. Any suggestions? It seems like what I'm doing is just enough outside the normal demand for DAL/ORM tools/tutorials online that I haven't been able to find anything. Or maybe I'm just overlooking something obvious?

  • hibernate modeling relationships managed through an intermediate table

    - by shikarishambu
    I have a datamodel that has an intermediate table to manage relationships between entities. For example, tables Person and Organization are related through the Relationship table Party (table) - ID Person (table) - ID (references Party.ID) - name Organization (table) -ID (references Party.ID) -name Relationship (table) -ID (PK) -type (references relationshiptype lookup) -fromID (references Party.ID) -ToID (references Party.ID) -fromDate -ToDate Type+fromID+ToID+fromDate+ToDate is guaranteed to be unique. How do I manage this using hibernate? TIA

  • SQL: Get count of rows returned from a left join

    - by Rogue Coder
    I have two tables, one called calendars and one called events. There can be multiple calendars, and multiple events in a calendar. I want to select every calendar, also getting the number of events in the calendar. Right now I have : SELECT C.*, COUNT(*) AS events FROM `calendars` AS C LEFT JOIN `events` E ON C.ID=E.calendar GROUP BY C.ID But that doesn't work. Items with no events still return 1. Any ideas?

  • Perl daemon script for message queue hanging for 20 seconds after each process. Why?

    - by Mike Diena
    I have daemon script written in Perl that checks a database tables for rows, pulls them in one by one, sends the contents via HTTP post to another service, then logs the result and repeats (only a single child). When there are rows present, the first one is posted and logged immediately, but every subsequent one is delayed for around 20 seconds. There are no sleep()'s running, and I can't find any other obvious delays. Any ideas?

  • Image jQuery scroller in a container. (like facebook cropper) can't get values of position.

    - by Stefan
    Hey all. Having a reallllll mind pain. I have a php image uploader which is all good and sotring the file and the jquery ajax is returning the image in an ammended html div with a div set up like this: #crop-holder { width:80px; height:80px; margin:10px 10px 20px 10px; border:1px #c0c0c0 solid; overflow:hidden; cursor:move; } The image is viewing fine and I am using the jquery scrollview plugin: http://code.google.com/p/jquery-scrollview/ I have tried adding a few lines to the plugin to store variables of scrollTop and Left and then replacing two hidden input values with x and y in my page. And then on the returned ajax html in the div I am trying to on a button click (for example) retrieve the values of the two hidden inputs.... Heres what i added to the plugin (i'm no js expert!): .mouseout(function(){ var _m = this.m; var lasty = _m.scrollTop(); getElementById("ycord").value = lasty; var lastx = _m.scrollLeft(); getElementById("xcord").value = lastx; self.stopgrab(); }) Still no luck!! How can I get the scrollTop and scrollLeft and successfully prepare them for sending onto another php script!? Thanks:) stefpretty

  • iOS: display modal view over the top of a UIWebView

    - by Sly
    Is it possible to display a modal view over the top of a UIWebView? I have a UIViewController that loads a WebView. I then want to push a Modal View Controller over the top so that a modal view covers up the WebView temporarily... The WebView is working fine; here's how it's loaded in the View Controller: - (void)loadView { // Initialize webview and add as a subview to LandscapeController's view myWebView = [[[UIWebView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]] autorelease]; myWebView.scalesPageToFit = YES; myWebView.autoresizesSubviews = YES; myWebView.autoresizingMask = (UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight); myWebView.delegate = self; self.view = myWebView; } If I attempt to load a Modal View controller from within viewDidLoad, however, no modal view appears: - (void)viewDidLoad { [super viewDidLoad]; // Edit dcftable.html with updated figures NSMutableString *updated_html = [self _updateHTML:@"dcftable"]; // Load altered HTML file as an NSURL request [self.myWebView loadHTMLString:updated_html baseURL:nil]; // If user hasn't paid for dcftable, then invoke the covering modal view if (some_condition) { LandscapeCoverController *landscapeCoverController = [[[LandscapeCoverController alloc] init] autorelease ]; [self presentModalViewController:landscapeCoverController animated:YES]; } } I suspect that there's something that needs to be done with the UIWebView delegate to get it to receive the new modal view...but can't find any discussion or examples of this anywhere...again, the objective is to invoke a modal view that covers over the top of the WebView. Thanks for any thoughts in advance!

  • Count of products NOT sold...per store, per day over the past month

    - by user1893510
    I'm struggling with an interview question. 3 dimension tables (Product, Store and Date) and 1 fact table (Sales). The question asks for a T-SQL solution that will return the count of products not sold, per store, per day over the past month. At this point, my answer is futile but I've spent significant time trying to back into a solution, to no avail, and would like to close the loop. Any guidance is greatly appreciated.

  • Linq to SQL: how get row security between write access??

    - by Francisco
    I would like to allow two threads to write in a table at the same time (I know the problem of updating the same row, but this would be a story apart). I need that in behalf of speed up the operations in my aplication (one thread could write in row X while another could do the same in row X+n instead of waiting the first to finalize). So, can I block rows instead of tables with Linq to SQL? Thanks.

  • How to create view in RoR if skipped during controller generation

    - by swapnesh
    When I run this: rails generate controller hello index it no doubt generates hello controller, but accidentally when I run another command like this: rails generate controller world it creates the world controller successfully, but missed the Route "world/index" like as "hello/index". For this mistake I need to use destroy controller and then generate it once more, is thr some kind of mid way command that I can generate if forgotten something rather than destroying and creating every time. This command rails generate controller contact-us index creates a route as contact_us/index or contact_us after changing routes.rb under config folder. How could I create a more SEO friendly URL in RoR? Like localhost:3000/contact-us? I am working on some very basic rules to follow RoR..like 3 static pages (Home, About us, Contact Us) Just simple html content to understand more, will certainly add more features to it as well. localhost:3000/home localhost:3000/About_us localhost:3000/contact_us I created this via creating home, About_us, contact_us controller command and then changed html in views. Since I am on an initial phase, I read somewhere for static pages we can create this in our public like what we have error pages there in the folder or the approach im using is correct?

  • jQuery: Adding li element only if it not already there?

    - by Legend
    I am constructing an <li> element like this: var element = $("<li></li>") .html(mHTML) .attr('id', "elemid"); I am trying to add this element to a <ul> element only if it doesn't already exist. Any ideas on how to do this? Am I supposed to use contains() to see if the ul element contain the html and then decide? For instance, <ul id="elemul"> <li id="elemli1">Element 1</li> <li id="elemli2">Element 2</li> <li id="elemli3">Element 3</li> </ul> If I try adding Element 1, it should not add it. What should I do if its a longer string (not really long but about 150 characters). Do I go about using hashmaps?

  • Understanding REST: is GET fundamentally incompatible with any "number of views" counter?

    - by cocotwo
    I'm trying to understand REST. Under REST a GET must not trigger something transactional on the server (this is a definition everybody agrees upon, it is fundamental to REST). So imagine you've got a website like stackoverflow.com (I say like so if I got the underlying details of SO wrong it doesn't change anything to my question), where everytime someone reads a question, using a GET, there's also some display showing "This question has been read 256 times". Now someone else reads that question. The counter now is at 257. The GET is transactional because the number of views got incremented and is now incremented again. The "number of views" is incremented in the DB, there's no arguing about that (for example on SO the number of time any question has been viewed is always displayed). So, is a REST GET fundamentally incompatible with any kind of "number of views" like functionality in a website? So should it want to be "RESTFUL", should the SO main page either stop display plain HTML links that are accessed using GETs or stop displaying the "this question has been viewed x times"? Because incrementing a counter in a DB is transactional and hence "unrestful"? EDIT just so that people Googling this can get some pointers: From http://www.xfront.com/REST-Web-Services.html : 4. All resources accessible via HTTP GET should be side-effect free. That is, the request should just return a representation of the resource. Invoking the resource should not result in modifying the resource. Now to me if the representation contains the "number of views", it is part of the resource [and in SO the "number of views" a question has is a very important information] and accessing it definitely modifies the resource. This is in sharp contrast with, say, a true RESTFUL HTTP GET like the one you can make on an Amazon S3 resource, where your GET is guaranteed not to modify the resource you get back. But then I'm still very confused.

  • Store children in database preserving information about their order

    I am designing database tables for a master-detail scenario. The specific requirement is that it is necessary to store information about the order of children. I see some possible solutions (like adding a column representing a position in the sequence, or a column with foreign key to the previous child) but I would like to know the best practices how to solve such problems.

  • How do I write object classes effectively when dealing with table joins?

    - by Chris
    I should start by saying I'm not now, nor do I have any delusions I'll ever be a professional programmer so most of my skills have been learned from experience very much as a hobby. I learned PHP as it seemed a good simple introduction in certain areas and it allowed me to design simple web applications. When I learned about objects, classes etc the tutor's basic examnples covered the idea that as a rule of thumb each database table should have its own class. While that worked well for the photo gallery project we wrote, as it had very simple mysql queries, it's not working so well now my projects are getting more complex. If I require data from two separate tables which require a table join I've instead been ignoring the class altogether and handling it on a case by case basis, OR, even worse been combining some of the data into the class and the rest as a separate entity and doing two queries, which to me seems inefficient. As an example, when viewing content on a forum I wrote, if you view a thread, I retrieve data from the threads table, the posts table and the user table. The queries from the user and posts table are retrieved via a join and not instantiated as an object, whereas the thread data is called using my Threads class. So how do I get from my current state of affairs to something a little less 'stupid', for want of a better word. Right now I have a DB class that deals with connection and escaping values etc, a parent db query class that deals with the common queries and methods, and all of the other classes (Thread, Upload, Session, Photo and ones thats aren't used Post, User etc ) are children of that. Do I make a big posts class that has the relevant extra attributes that I retrieve from the users (and potentially threads) table? Do I have separate classes that populate each of their relevant attributes with a single query? If so how do I do that? Because of the way my classes are written, based on what I was taught, my db update row method, or insert method both just take the attributes as an array and update all of that, if I have extra attributes from other db tables in each class then how do I rewrite those methods as obbiously updating automatically like that would result in errors? In short I think my understanding is limited right now and I'd like some pointers when it comes to the fundamentals of how to write more complex classes.
