Yes, but if the user has JS disabled, you have a problem. What I typically do is have two separate actions, a delete and a do_delete. The delete action merely displays the record and has a form (link, whatever) asking Are you sure?, and then if they agree, you perform the do_delete that does the business. You could also have a single delete action but with a confirm parameter signalling that you're really deleting, etc. There are lots of options. You can pair this with JS if you want.

Re: [Catalyst] Newbie Question about Database
lol I know but I'm doing this inside a private lan where we are building this app with my coleagues :p of course later on we will have specific accounts with limited access Your colleagues can be your biggest security problem. It just takes an argument...a jealousy...someone who feels belittled...someone who just wants to take advantage of lax data security. It is real good practice to use least-privilege access to data from the very beginning. Exactly, also how many of those we will of course do X later...

[Catalyst] Custom fields in a model
I have a database table -- let's call it 'Contacts' that I'm accessing through a DBIx::Class model. This table has two fields called 'first_name' and 'last_name'. Could I get some suggestion on the best way to add code to the model (or the schema) to allow me to add a custom field to the resultset without having an actual column in the database table? I want to be able to access a field in the resultset called something like 'common_name'. This field would contain a concatenation of the first and last name fields for people and only the data from the last name for other entities like businesses. Thanks!

Ok, so, as a favour to the UKUUG and to Dave Cross, founder of the illustrious london.pm and person mad enough to let me split the tutorial time at the London Perl Workshop 2008 with him, I hereby re-appear on the lists to point out that there are tutorials going on, and those of you attempting to get people up to speed or rescue PHP developers or whatever might be interested in it. So, if you are interested, here's the details - UKUUG (in conjunction with O'Reilly) presents: Introduction to Perl - 25th February 2009 Advanced Perl Techniques - 26th February 2009 Tutor: Dave Cross see: http://www.ukuug.org/events/perl09/ Day 1: Introduction to Perl - 25th February: This one-day course is an introduction to Perl for complete beginners. No knowledge of Perl is assumed, although attendees will have a slight advantage if they have some knowledge of at least one other programming language. At the end of the course, attendees will have enough knowledge to write a number of useful Perl programs, together with details of where to go for more information. Syllabus: What is Perl Input and output Creating and running a Perl program Regular expressions Perl variables References Operators and functions Finding and using modules Conditional constructs Smart matching Subroutines Day 2: Advanced Perl Techniques - 26th February: Perl has come a long way since the scripting language which powered most of the world wide web in the 1990s. There are many ways to build applications in Perl. In this course we will look at some powerful techniques which are used by the best Perl programmers in the world. This one-day course is aimed at programmers who have been using Perl for some time but who may not be completely up to date with the latest Perl techniques. At the end of the course attendees will have a number of modern Perl programming techniques to their programming toolkit.

* Jesse Sheidlower jes...@panix.com [2009-01-21 15:55]: What I typically do is have two separate actions, a delete and a do_delete. The delete action merely displays the record and has a form (link, whatever) asking Are you sure?, and then if they agree, you perform the do_delete that does the business. You could also have a single delete action but with a confirm parameter signalling that you're really deleting, etc. There are lots of options. You can pair this with JS if you want. Best approach for pairing with JS: Do the above, ie. if the user GETs the link, you send back a form with POST and OK/Cancel buttons which they can use to POST the delete request. *Then*, use inobtrusive JS to modify the links, so that they first pop up a confirm dialog then submit a hidden form if the user says OK. That way users who have Javascript get asked OK/Cancel with a popup and they send a POST immediately. And users who don’t have Javascript get asked OK/Cancel on a separate page. And deletion is safely shielded behind a POST action in both cases. (I should make a jQuery plugin out of this sometime…) First rule of web apps: merely following a link (or typing into the browser address bar and hitting Enter) should NEVER EVER result in a destructive action, no matter what URL the user typed. Remember that following links need not be intentional. Your browser follows far more links automatically without telling you than the number of links you ever actively click on: every image, every stylesheet, every script, every frame, every Flash object on every page you visit is downloaded automatically. Now consider what happens if a malicious user puts img src=http://yourapp.example.org/addressbook/delete/all; into a page they control and then send a link to that page to your users. If you allow destructive actions on GET, you have just allowed for your users to be screwed over through no fault of their own.

This thread has been beat to death, but one other point: What do *you* think the vast majority of times you click Delete and are then asked Do you really want to delete? Of course I want to delete it, that's why I clicked that big fat delete button. The javascript confirmation is easy, and I do it all the time, but when not so lazy and the action lends itself I provide an undelete option afterwards for those rare oops times. -- Bill Moseley mose...@hank.org Sent from my iMutt ___ List: Catalyst@lists.scsys.co.uk Listinfo: http://lists.scsys.co.uk/cgi-bin/mailman/listinfo/catalyst Searchable archive: http://www.mail-archive.com/catalyst@lists.scsys.co.uk/ Dev site: http://dev.catalyst.perl.org/

On the other hand you might want a non-javascript undo option at the other end if you go that route. Duh, I should know this, but do screen readers support JavaScript? It depends on what the JS script does. If it draws a menu for example, it won't be accessible, but if it just hides/shows a div with menu elements, it would be accessible in some cases, but probably not for all the screen readers. For just showing a confirmation window, JS is accessible for the screen readers. The most annoying thing however is to use links that use JS code in the href attribute instead of associate it with the events like onClick. This is because when the user makes a shift+click or shift+enter on a link in order to open the new page in a new window, it just displays an error because the browser can't access an url like javascript:DoPostBack() It is also very annoying to need to open a link like # or . I think that if the user presses shift+enter, he knows that this will open the page in a new window, so the href attribute should contain the full URL to the targeted page. Of course, if the URL should change something on the server, that page that opens directly (without JS) should contain a form that asks for a confirmation.

Re: [Catalyst] Tool for rendering web pages consistently though time ?
From: lanas la...@securenet.net Hi, I'm looking for a tool/procedure that could render web pages in a consistent manner without having to rely on the screen resolution and fonts of a workstation so that, through time - and through many OS updates of various sorts - it'd be possible to always render the pages in the exact same way, for documentation purposes. Perhaps some kind of virtual screen that always uses the same parameters and whose output whould be in svg of jpg. Is there a way of doing that ? Thanls for any ideas/suggestions. I hope there isn't. Such a documentation would be targeted discriminatory only to the sighted users, and this is not nice at all.
