style problem
by Dmitry Dorofeev 12 Sep '05

12 Sep '05

Hi, I am using seaside 2.5 When I use 'style' method in the component which is the root (or say WAApplication subclass), it is applied. When i use style method in the plain component, styles are not applied. Is it correct and desired behavior ? Thanks, -Dmitry.

Gemstone IS pricy for commercial apps, but you can get a free version either from their site, or from cincom.com. Once your temp license runs out, you email gemstone and ask for another one. Works great for development projects. ________________________________________________________________ Sent via the WebMail system at mail.yans.net

I agree with a large part of all that, however, Smalltalk is IMHO, superior to Ruby, and given that fact, why shouldn't it be able to handle basic CRUD just as easily? This doesn't mean Seaside needs to do this, Seaside is fantastic as a base framework for developing really complex workflow style applications and shouldn't be overburdened with everything. But Smallwiki2 and Magritte, now that's the framework to enable simple programming-less CRUD. With Seaside as it's foundation, and Magritte's meta-descriptions, components, and composeable containers, and prevalence style persistence, Lukas is very close to having the capability of point and click CRUD application development with no programming, no databases, and no templates of code you have to specialize ala Rails. Like it or not, most complex apps start out with simple CRUD and build from there, you have to start somewhere. Seaside/Magritte/Smallwiki2 is a killer combination that IMHO will shortly surpass Rails in it's ease of use to the point that non programmers could possibly build simple applications with little to no training, and real programmers can use Magritte directly via code to make building "any" complex Seaside application much faster and easier.

I think that's probably the correct behavior, however, so this method should be: getAddressWithMessage: aString ^ self call: (WAStoreAddressEditor new validateWith: [:a | a validate]; addMessage: aString; yourself) I'll commit that fix shortly.

Store Demo Broken
by Ramon Leon 11 Sep '05

11 Sep '05

Anyone notice the store demo doesn't work anymore if you try and check out. Seems like addMessage: is being sent to a WAValidationDecoration, but it's a subclass of WAPresenter, rather than WAComponent which can handle that message? I'm running latest 2.6a2v5. getAddressWithMessage: aString ^ self call: ((WAStoreAddressEditor new validateWith: [:a | a validate]) addMessage: aString) results in... MessageNotUnderstood: WAValidationDecoration>>addMessage: * WAValidationDecoration(Object)>>doesNotUnderstand: #addMessage: self a WAValidationDecoration temps aMessage addMessage: 'Please enter your shipping address:' inst vars next a WAStateHolder(a WAFormDecoration) message a WAStateHolder(nil) validationBlock [] in WAStoreTask>>getAddressWithMessage: {[:a | a validate]} exceptionClass nil * WAStoreTask>>getAddressWithMessage: self a WAStoreTask temps aString 'Please enter your shipping address:' a nil inst vars decoration a WAStateHolder(a WATransaction) cart a WAStoreCart

Seaside2.6 a1 vs. a2
by Wilkes Joiner 11 Sep '05

11 Sep '05

What are the differences (in general) between the a1 and a2 branches? Is a2 an experimental branch and a1 the main branch for the 2.6 release? Just curious about which one I should play with. Thanks, Wilkes

[ANN] Squeak Foundation

Hi all Since a year, we (marcus and me and some others) have been playing with the idea that Squeak deserves a foundation and after several tries, we decided to doit! Have a look at: http://smallwiki.unibe.ch/squeakfoundation Now we are nearly ready for the prime time. We hope that you will like it and support it. Read the actions: http://smallwiki.unibe.ch/ squeakfoundation/actions/ and the goals and principles: http:// smallwiki.unibe.ch/squeakfoundation/foundationgoalsandprinciples/. In a nutshell we want to make sure that we get an organization that pushes the visibility of Squeak and that enables Squeak to be a platform of development for all kinds of applications (educations, multimedia, web developments, research), but also support the production of books, videos... We want to make sure that Squeak continues to be maintained even if we stop. We want to be able to pay a cleaner a day a week to support the harvesting and bug fixing. Squeak needs to have more users and companies selling products with it, because the more we will be the more we will be to fix and enhance the system. Now this is not a private club, if you want to REALLY help, you are more then welcome, we have a lot to do CD, DVD, merchandising, website, projects... But pay attention that we are looking for people not only talking :). Now if you like the idea but you do not have the time but trust us for all the good job we did over the years then support the foundation, read the http://smallwiki.unibe.ch/ squeakfoundation/supporters/ page. To speed up the bootstrap we asked ESUG to host it and also to sponsor it. They accepted and gave us some money to start (2000 Euros) and noury the ESUG treasurer accepted to have separate accounts and deal with the money issue. Stef, marcus, noury, and few others...

Seaside & Ruby Rails Compared
by Chad Nantais 09 Sep '05

09 Sep '05

I have been using Ruby on Rails and was wondering if Seaside can do some of the things RoR can do (without much development on my part). If it can do these things easily, I would consider moving to Seaside because I like the Squeak environment and Smalltalk language. Can Seaside perform: 1. Functional testing 2. Unit testing 3. User authentication 4. MySQL connectivity Thanks. -- Chad cnantais(a)gmail.com

I have tried the > prepared image and installed into 3.9a, and in both the > seaside session seems to hang when I try to save a change to a page. > > Since I get no clues on the smallwiki list, I will beg here! :) Yes, I'm using them, but it's very new to me, I spent about 8 hours after work last night digging into it and trying to grok it, so anything I say could be totally wrong, but I think I'm starting to get the basics of it. I use it with 3.8, Seaside2.6a2v5(current latest version), SeasideAsync, and latest versions of Magritte-All and Smallwiki2-All, haven't had any issues with saving pages or lockups. Load those in a fresh image and you shouldn't have any problems. >From what I can see so far, it's a hybrid Adaptive Object Model, Magritte descriptors can be used to describe existing classes, they are collected into a MAContainer which can then be sent the message asComponent to edit the descriptors, or sent to MAScaffolder description: aContainer to get the actual component described by the descriptors. Descriptors have a matching default Seaside Component for rendering them, several have more than one, which you can specify when building the description. The Adaptive Object Model comes into play because apparently, unless I'm mistaken, you can compose objects from descriptors dynamically, without actually needing a class underneath. Still digging into this part but it seems that instances of MAScaffolder are adaptive objects, they have a description that points to the MAContainer that built them, essentially its type (Type Object Pattern), and a values dictionary representing the values of its properties, keyed by the children descriptors of it's type/description. So instances of MAContainer appears to be playing the class role, and instances of MAScaffolder play the role of instances of that class. With the little documentation available, I can't guarantee my interpretation is correct, but that's what I've learned so far from digging into it last night.

2 FAQ suggestions to be included
by Dmitry Dorofeev 09 Sep '05

09 Sep '05

Hi All. Q. How to speed up file uploads ? A. Use FastSocketStream available on SqueakMap. Once installed in your image, change HttpAdaptor class >> # readAndWriteToSocket:service: to read as readAndWriteToSocket: aSocket service: httpService ^self readAndWriteTo: ((FastSocketStream on: aSocket) timeout: self dataTimeout; autoFlush: false; yourself) service: httpService Q. How to use Apache as frontend to Seaside (and serve static images with Apache) A. You may use a mod_proxy. Make sure that 1. mod_proxy is included into your apache installation for apache 1.3.x check lines in apache config similar to: LoadModule proxy_module libexec/libproxy.so AddModule mod_proxy.c 2. in your seaside app config (http://localhost:9999/seaside/config and click configure link against your app) 'Server Hostname' is empty and 'Server Port' is 80.(i.e. defaults) Sample Apache config assuming you have Seaside running on localhost:9999 and your app is on http://localhost:9999/seaside/test <VirtualHost X.Y.Z.A:80> ServerName www.test.com #Static files are placed here and /home/seaside/static/test.gif is # available via http://seaside.test.com/test.gif DocumentRoot /home/seaside/static <Directory /home/seaside/static> Options Indexes </Directory> UseCanonicalName off NoCache * ProxyRequests On # http://www.test.com/seaside/test is our app now!!! ProxyPass /seaside/test http://localhost:9999/seaside/test # This should work too # ProxyPass /app http://localhost:9999/seaside/test </VirtualHost> Feel free to amend it with more details -Dmitry
