Automated build
by Mart-Mari Breedt 15 Jun '05

15 Jun '05

We are trying to automate the building process starting from a clean image and then loading packages, mcz's, sar's etc... So far we have been successful, but we keep on running into little scenarios that still requires user interaction like: * A prompt for loading an older dependency than the one already installed * The prompt for entering the administrator's username and password for the seaside config app. * Some applications require you to enter you initials before continuing. (Like when installing ODBC) Does anyone have any idea how to get around these prompts in order for the build to run without any user interaction? Thanks, Mart-Mari

Re: Seaside Digest, Vol 30, Issue 18

Hi, I have similar question: I've got a select box and I want to update contents of one textInput when selection is made (like in usual file choosers). I think it is sufficient to use JavaScript to fill the textInput's value instead of LiveUpdate. Can somebody point me to an example how to attach JavaScript to selection please? thanks -- .:jbk:.

dynamic selection - liveCallback question
by Florian Minjat 14 Jun '05

14 Jun '05

Hi, I would like to have two select on the same page, and the content of the second one would depend on the content of the first one dynamicaly. I tried something with the liveCallback: renderContentOn: html html form: [ html selectFromList: #(a b c) selected: #a callback: [:sel] labels: [:ea | ea asString] liveCallback: [:sel :h | selected := sel. self renderContentOn: h]. ]. html form: [ html selectFromList: ((selected = #a) ifTrue: [ #(aa bb cc)] ifFalse: [ #(ba bb bc) ]) selected: #aa callback: [:sel] labels: [:ea | ea asString] ]. where selected is an instance variable. But it's not working, the variable is well changed, but I have to refresh the page in order to make the second select change. I could not find any documentation on how to use the liveCallback for changing something different from a span. Does someone have an idea on how to do this? Florian

The WAOnce decoration is missing from the current distribution (the test for it is there though, now that's extreme programming :-)) rado

setting up security on components
by James 12 Jun '05

12 Jun '05

Hi all, I am trying to set up a security system on an application where different users will have the rights to see different components. By default a user will be set as a Guest account and stored in a subclass of WASession. When they try to view a secured component it should check if they have permission. If they do the component is shown, if they do not a login dialog is shown. If they login successfully their new user is stored in the session and the component retries the check for permissions. I have tried to implement this by defining a WASecuredComponent class which is a subclass of WAComponent. This has the following methods renderContentOn: html self checkPermission. checkPermission (self session user checkPermissionTo: self ) ifFalse: [self requestLogin. self checkPermission.] requestLogin (self call: WALogin new) ifFalse: [self requestLogin]. Classes to be secured extend WASecuredComponent and have to start renderContentOn with super renderContentOn: html. WALogin extends WALoginDialog and contains login | user | user := WAUser verifyPassword: password forUser: username. (user userId > 0) ifTrue: [ self session user: user.]. self answer: (user userId > 0). At first it all seems to work OK. I get the login dialog if I don't have permission to view the component. Entering an invalid password or one without permission on the component leads to the login dialog showing again. Entering a correct password leads to the secured component showing. However if I try to do something with the secured component, such as post a form on it, I get the "Components not found while processing callbacks: #(a TAG.WAForm)" error. I know this error usually means a problem with a children method, but I can't see how that could be the case in this situation, particularly since my application has successfully shown the login form and the secured component already. I have tried to debug, and it seems that the secured component is still delegated to the login form, despite the fact that the secured component has just been visible. Am I going about this in the wrong way, or is there a mistake in my implementation? I don't think the User, Session and other classes are relevant to this problem - let me know if their definitions would help. If it makes a difference I am using VW 7.3 Many thanks James Bridger

WACanvas, WABrush, and liveUpdate
by Wilkes Joiner 11 Jun '05

11 Jun '05

I really like the new WACanvas and WABrush classes. They should be much more flexible going forward. I added support for the liveUpdate Javascript library. I thought that this would be a good way to get familiar with the new classes and that you guys might find them useful. I just ported the existing Live test page to use the WACanvas classes. It is under the "Live Canvas" tab. I had some problems with the script: method escaping the ampersands. I'm not sure if my fix is really appropriate given my ignorance of the new approach. These were created off of Seaside2.6a1-avi.43 - Wilkes

Should I use Comanche > or Apache? Using Comanche and Apache aren't exclusive: it's common to have Seaside on top of Comanche serving dynamic content, but all behind Apache which serves static content and proxies the dynamic requests through to Squeak. For database, it depends a lot on what kind of data you're dealing with, and how much of it. You may find that the simplest way to start is simply to keep the data inside the Smalltalk image, and periodically write it out to or reload it from a flat file. If you want a more "real" database, GOODS is probably the easiest to get started with, with OmniBase offering better performance (and certainly better *control* over the performance) but with a much steeper learning curve. Or, if you're comfortable with relational databases, there are several options (like GLORP and ROE) for working with PostgreSQL - but I wouldn't recommend that unless you're already SQL-savvy. Avi

Emission of static web pages?
by Greg Lewin 10 Jun '05

10 Jun '05

Hi, I've played with Seaside a bit and like the look of it, and have been keen on Smalltalk for a long time, which adds extra interest. I've looked at the documentation and don't see any obvious answers to this: While Seaside is clearly great for dynamic pages, and as a development environment, I've been wondering how easy it is to emit a static set of completely self-sufficient, stand-alone web pages which can be propagated to another web server. If it is easy, this would make it even more useful to more people - e.g. those who don't want to use Squeak as a web server ( i.e. commercial hosts). I apologise if the answer is yes and it's obvious, but I haven't seen it yet. Thanks for a very nice product. Greg
