So rather than using inheritance, use composition, have your repository include a set as a member variable, to hide the implementation, and simply delegate only those protocols a repository needs to the internal collection, because you will need to change it later.

[OT] Case insensitive comparison not stable ?
by Francois Beausoleil 11 Jan '06

11 Jan '06

Hello everyone ! I know this is off-topic, but at least recognize a few names here :) Anyway, I can't seem to sort a set of objects represented by names case insensitively. Here's what I have at the moment (some methods omitted for brevity): Object subclass: #Author instanceVariableNames: 'name email messages' classVariableNames: '' poolDictionaries: '' category: 'Message-Board-Model'! <= other ^ name caseInsensitiveLessOrEqual: (other name) Set subclass: #AuthorRepository instanceVariableNames: '' classVariableNames: '' poolDictionaries: '' category: 'Message-Board-Model'! sortedByName ^ SortedCollection new addAll: self. If I repeatedly "Do it" the following in the Workspace, I see the names jumping around. Also, most of the time, Stefanny is on top, instead of Francois ? |ar| ar := AuthorRepository new. ar add: (Author new name: 'francois'). ar add: (Author new name: 'stefanny'). ar add: (Author new name: 'Kelly-anne'). Transcript clear. ar sortedByName do: [:author | Transcript show: author name; cr.] So, what am I doing wrong here ? I'm on Squeak 3.8. Also, for the future, where should I be asking questions like that ? Squeak-dev ? Thanks ! -- François Beausoleil http://blog.teksol.info/

new user curious about use of GLORP with Seaside on Squeak 3.8
by Michael Kohout 11 Jan '06

11 Jan '06

Hello- I've been curious about and have dabbled in Smalltalk in general (and Squeak in particular) for a while but only recently I've become aware of Seaside. From what I can tell, for the most part I like it and have decided to write a proof of concept application for my department. My largest requirement for this proof of concept is that I can use some Object Relational Mapping system that works for Postgres(development) and Oracle(production). To this end, I decided to try using GLORP, but I can't get the required Postgres client(v 0.9.2) to install into my image. If there is a patched version of this client, or some other postgres client out there could someone point it out? What is the most common pattern for Seaside applications? What do you use to persist stuff to a relational database? thanks for any insight you can provide. Mike Kohout Software Engineer Minnesota State Colleges and Universities

Generating a text and anchor in a list item with canvas API like #list:do: used to
by Yar Hwee Boon 10 Jan '06

10 Jan '06

Is there a way go generate lists with items that allows a block to control what is rendered for each item? For eg. Item 1 (delete), where "Item 1" and delete are 2 separate anchors? ie. with the old API: renderContentOn: html html list: #(1 2 3) do: [:v | html anchorWithAction: [self edit: v] do: [html text: 'Item ', v displayString]. html text: ' ('. html anchorWithAction: [self delete: v] do: [html text: 'delete']. html text: ')'] Thanks. -- Hwee Boon http://motionobj.com/ MotionObj (65) 6764-9774

File downloads etc

Hi guys! Ok, this has surely been discussed a *hundred* times - but I just started digging into Seaside for real so forgive me. And yes, I did search a bit with Google first. :) The question is: How do people serve files with Seaside? Especially static files like images? And no, you don't need to reply if you use Apache or HV2 on the side :) - I am interested in the "Seaside way" here. And in my current project an external web server is a no-no. Using HV2 would be an option but I am learning Seaside now. I started digging of course and found WADocumentHandler - but uncommented, as well as all the handler classes in fact, ehrm, <insert coughs here>. IMHO this is a lacking in Seaside - just a *teeeeny* bit too few class comments. :) ...and why does WADocumentHandler>>response send #text to the content stream btw? Anyway, suppose we add these two methods to WAImageTag: WAImageTag>>fileName: aFileName mimeType: mimeString "Create a document handler for the file contents and insert a URL for it. The document will be served binary and with a non expiring cache." ^self url: (canvas context urlForDocument: ((StandardFileStream readOnlyFileNamed: aFileName) binary; contentsOfEntireFile) mimeType: mimeString fileName: aFileName). WAImageTag>>fileName: aFileName "Create a document handler for the file contents and insert a URL for it. The document will be served binary and with a non expiring cache." ^self fileName: aFileName mimeType: (MIMEDocument guessTypeFromExtension: (FileDirectory extensionFor: aFileName)) Note how we don't send the filestream itself but fetch all its contents first - this is because otherwise the filestream gets put into the WAResponse which never closes it. Darn. So perhaps it was never meant to send a FileStream into #urlForDocument:. Now, given how it works today (the WAResponse>>writeOn: will eventually send #contents to the stream and write that) there is no real point in sending the stream, so I read it all into memory myself, close the filestream and send the ByteArray or String. The downside is of course that we end up with all these loaded into the image, but for small images etc it is not a big deal. I assume these handlers stick around for the session lifetime? Hmmm, ok even longer (http://lists.squeakfoundation.org/pipermail/seaside/2005-February/00441 1.html). And yes, above we could be smarter regarding where to look for files etc. End usage with WACanvas: MyComponent>>renderContentOn: html html image fileName: 'myimage.gif' regards, Göran PS. I assume WAImageTag>>resourceUrl: is for referring to stuff served by some other server? Or have I missed something?

Yup, that's why Seaside's got me, no matter the problem, I fix it in one language, Smalltalk. I get paid to work in ASP.net, and let me tell you, I'm so sick of having to work in and constantly switch back and forth between HTML, XSLT, XML, C# and SQL, all so I can do 10x the work I'd have to do in Squeak to get an app that's half as cool and takes way long to write. Ruby reduces the syntactic annoyances, but it keeps all the environmental annoyances, it's the same old architecture, lot's of text files, HTML templating, SQL, same old stuff, just on a diet, it's evolution. Seaside is revolution, a new better way. Ruby is the bridge by which Java/C# programmers can approach Smalltalk without losing their minds, so it only helps Smalltalk in the long run. In the mean time, Seaside is a secret weapon, I don't mind it staying that way.

They are already cached across sessions. The idea behind the current approach is that their URL changes IFF the content changes, so that they can be cached forever. > Moreover, i would like to make it possible to return a mime > document so that files can be served without the need to tweak > something with the web-server.

Hi Lukas, I've done that in VisualWorks. If you happen to have VisualWorks at hand, there is a parcel named SeasideWebDesignerTool that includes a WAPictureServer (subclass of WARequesthandler) and a WAPictureHandler (subclass of WADocumentHandler) These things are able to serve urls like : .../seaside/images/MyClass/MyMethod.jpg The parcel includes a sample (Douglas Bowman's Sliding doors) that demonstrates CSS that is invoking pictures directly from Seaside. The parcel is also able to upload graphic files into Smalltalk methods, a bit like your FTP server. Hope this helps.
