defining relationships...
by sergio_101 26 Feb '10

26 Feb '10

okay, i am really almost there.. i just need to understand how to define relationships between models .. for example.. if i have the following objects: Object subclass: #Artist instanceVariableNames: 'name formationYear ' Object subclass: #Album instanceVariableNames: ' albumName releaseDate numberOfSongs duration' Object subclass: #Song instanceVariableNames: ' title duration' in this case... an artists has many albums an album has many songs and a song has and belongs to many albums (it can be on the original release, or it can be on a best of album).. so, in this case, how would i define my instance variables to show these relationships... and how would i grab all songs that belong to a particular album? ie.. how would i say: give me all fleetwood mac albums or give me all songs on the album 'tusk' or give me all albums that "don't stop" shows up on thanks so much! -- ---- peace, sergio photographer, journalist, visionary http://www.coffee-black.com http://www.painlessfrugality.com http://www.twitter.com/sergio_101 http://www.facebook.com/sergio101

(New) tree widget in Seaside
by Magnus Schwarz 26 Feb '10

26 Feb '10

I was wondering whether it would be possible/a good idea to exchange the current script.aculo.us tree widget with something more easy to use, for instance jsTree? If you use the current tree it is quite hard (for users of your web pages) to properly drag&drop because parts of the tree "jump around" as you move one item and you have to be very careful where to drop to get the intended change. In jsTree (for example) it is much easier for users to use drag&drop properly, but: - jsTree is based on jQuery - if you want to use jsTree and Prototype based stuff on the same web page you probably have to use jQuery.noConflict() and patch the complete jsQuery library (?) - you once again have the the problem that parts of jsQuery are organized in sub folders. Maybe it is also time to renovate the WAFileLibrary in order to support (virtual) paths and sub folder structures and move away from keeping the filename in the method name (which was a nice idea for starters) but inside some other structure (in VisualWorks we can use pragmas but AFAIK there is nothing comparable in Squeak/Pharo?). Any ideas/comment?

Thx, Lukas, didn't know that.

JS - onclick="return confirm('Are you sure?')"
by John Thornborrow 26 Feb '10

26 Feb '10

Hi all, I'm loving the new JS api, however when I try to achieve the above in an #onClick: event, it is proving difficult to do so via the javascript API. I'm probably missing something, but it seems the only way to do so, is to use a literal string, e.g.: html button type: 'submit'; onClick: 'return confirm(''Are you sure?'')'; callback: [self doSomething]; text: 'Click me!!1' I've tried with various #confirm: sends, and the nearest I can get is: (html javascript return: true) confirm: 'Are you sure?' But this prints: if(confirm('Are you sure?')){return true} Which, as it doesn't have a "false" path, means it will always submit. Am I missing anything? :) Consider your responsibility to the environment - think before you print! ****************************************************************************************************************************************** This email is from Pinesoft Limited.

SUAccordion broken
by AA 26 Feb '10

26 Feb '10

While we're on the topic of SULightbox being slightly broken, SUAccordion is also suffering a problem, specifically when closing an accordion body - the accordion snaps rather than slides back... The problem is in the SUAccordion 'scriptHide:on' method: scriptHide: anElement on: aScript | index | index := self findIndex: anElement ifAbsent: [ ^ self ]. aScript scriptaculous effect id: (self uid: 'body' at: index); " onAfterFinish: (aScript prototype element id: (self uid: 'body' at: index); remove);" duration: 0.3; blindUp. aScript prototype element id: (self uid: 'head' at: index); removeClassName: 'active' The commented-out section is the offending one. (Sorry, I know this should appear in the Dev mailing list!) Amir

Re: SULightbox style 2.8.4 vs. 3.0
by Bob N. 26 Feb '10

26 Feb '10

Yes, but it's not my code I'm looking at, I'm looking at SUAllComponentTests in an unmodified Squeak Seaside 3.0a5 image, which has PTDeploymentLibrary. The SULightboxText seems broken. I use the latest one-click images to compare my VW 7.7 Seaside code with, so I was surprised that I had the same symptom as the Squeak image. It's probably something silly... I'd just like to know what.

Magritte & Seaside 3.0
by John Chludzinski 25 Feb '10

25 Feb '10

Lukas, is there a version of Magritte that's compatible with Seaside 3.0? I loaded Seaside 3.0 into the latest Cobalt release (opencobalt-1.0alpha1rc30renci 2), then tried to install Magritte - that failed. There appears to be compatibility issues with Seaside 3.0. I've installed and am using Seaside 2.9 with Magritte but 3.0 seems to be a bridge too far. Any help? ---John

weird CSS behaviour
by AxiNat 25 Feb '10

25 Feb '10

Hi all! I have finally been able to get my domain working and stuff, now I have a very weird problem for which I can seem to find no workaround... The thing is that the CSS is not loaded at all when I access my website normally at www.asmalltalkbytheseaside.com, but it works perfectly when accessing it like http://www.asmalltalkbytheseaside.com:8080/seaside/asmalltalkbytheseaside The code I'm using to retrieve the css file is: style |aCSSFile theCSSdata| aCSSFile := FileStream fileNamed: '/var/www/style.css'. theCSSdata := aCSSFile contentsOfEntireFile. aCSSFile close. ^theCSSdata I wrote the absolute path of the file to make sure there was no problem with different working directories, but it didn't solve anything. The other problem is that files/ASBTSFileLibrary/whateverfile.ext is not working either (ex. http://www.asmalltalkbytheseaside.com/files/ASBTSFileLibrary/MANUAL-EN.txt) Anybody had similar problems? Any ideas? -- Jonathan Swift<http://www.brainyquote.com/quotes/authors/j/jonathan_swift.html> - "May you live every day of your life."
