[ANN] Seaside+Pier+Magma image available

by Keith Hodges

First (alpha!) release of Pier running with Magma Persistency. Image available from ftp.seasidehosting.st User: preloaded Password: squeak enjoy Keith ------ Image Use Instructions In pier configuration click on 'Magma Control Panel', which will inform you that the repository does not exist. If you have placed this image on seasidehosting then you will have to manually create the repository directory. Given the list of options as to what repository to create, click the 'create' button (and wait). The existing pier kernel should appear in the list with a 'persist' button next to it, click 'persist'. Then try it and see! ------ ------ Detailed Log of Image Creation Steps (alternative title: "monticello tutorial") This image was prepared as follows: Beginning with Squeak3.8-6555full Initial start asks for updates: select "do not ask again" - this is important should you wish to deploy. Headless servers (e.g. seasidehosting) cannot handle user interaction and will stop at this point. From "world menu > open.... > Monticello Browser" Browser opens with (Monticello....) Click the "+Repository Button", select "HTTP" as the repository type, and enter MCHttpRepository location: 'http://www.squeaksource.com/Seaside' user: '' password: '' as the repository info (if you have a login on Squeaksource then you can enter your initials as the 'user' above.) Add the following repository for Monticello. MCHttpRepository location: 'http://www.squeaksource.com/Monticello' user: '' password: '' Add the following repository for Magma. MCHttpRepository location: 'http://www.squeaksource.com/MagmaTester' user: '' password: '' and the following two repositories for Magritte and Pier MCHttpRepository location: 'http://mc.lukas-renggli.ch/magritte' user: '' password: '' MCHttpRepository location: 'http://mc.lukas-renggli.ch/pier' user: '' password: '' also: MCHttpRepository location: 'http://www.squeaksource.com/OmniBrowser' user: '' password: '' (to edit this information: click the menu button in the right hand pane of the Monticello Browser) ---- Loading Latest Monticello. More recent versions of Monticello provide better feedback as to which packages are currently loaded. Select the http://www.squeaksource.com/Monticello repository, click "open", select the latest package (Monticello-avi.279) from the main "Monticello" branch, and click "load". Select the Monticello package on the left hand pane, and the squeaksource/Monticello repository in the right hand pane. Click 'open'. In the repository browser, click on the latest version (Monticello-avi.279.mcz) and click 'Load'. ---- Loading Seaside Select "world menu > open... SqueakMap"... and a dialog will ask if you wish to upgrade SqueakMap. Which you do. Notice that SMBase, SMLoader packages appeaer in the Monticello browser, since the upgrade is performed by loading Monticello packages. In SqueakMap, select the ever so convenient "Seaside Installer" which should load in the whole of seaside with its dependencies in one go. To do this select the left had pane menu button, "install". (Part way through the install you will be prompted to enter an admin username (seaside) and password (admin)) (if SqueakMap doesnt work it is being knobbled by a more recent package-cache, remove it and try again) Select the seaside repositoryClick the "open" and the repository browser will open. Select Seaside2.6b1 which is the current latest. In the right hand pane are the releases. Releases may be made by anyone and they may be small branches off from the main stream. Periodically an effort will be made to ensure that all changes are merged. Click the history button in order to browse the history of this package to get some idea of what is going on. Look at the ancestors of a package to see if one version is being sequentially built on the next, or whether any branching is occurring. Seaside is fairly mature and changes infrequent, therefore it is likely to be safe to grab the latest version. Loaded Seaside2.6b1-mb.79 Loaded Scriptaculous-lr.137 To start Seaside doit: WAKom startOn: 8080. ( Or use the "beach flags" SeasideMorph available from: http://minnow.cc.gatech.edu/squeak/5862 ) To test if everything is running, check the following url in your normal web browser. http://localhost:8080/seaside/config you should be prompted for you username and password (as given earlier). ---- Loading Magma Back to the Monticello Browser. Deselect the selected package by clicking on it once. This should re-reveal all of the registered repositories. (It is worth saving this. In the right hand side pane menu button there is a menu item: "Save Repositories", which writes a simple configuration script to the working directory.) Select the http://www.squeaksource.com/MagmaTester repository, and click "open". Select MagmaServerLoader, and click "load".

Customizing views in Magritte

by Norbert Hartl

Hi, at the moment I'm playing with magritte to test if it is suitable for my web application which is done with seaside. I created a model and I'm able to use it as a component with seaside. I have a model where ClassA has a 1:m relationship to ClassB. The exception here is that there is a fixed set of possible instances for ClassB to choose for the reference from ClassA. So what I need on the html rendering side is a kind of a pull-down and not an extra form for creating new instances of ClassB. I read the tutorial.pdf. There are three possibilities mentioned to customize the views for the model. Unfortunately I didn't figure out how this is working. The mentioned method defaultContainer (which should be overridden) doesn't exist in the magritte version I use. (I is the newest from Monticello) I even tried to set a new componentClass in the descriptionFoo class method.But with no effect. I'm not sure what I'm doing wrong. Magritte seems to ignore every step I take to customize. What would be the best way to customize on the class or even better on description instance side? Why is there an extra componentRenderer? As far as I figured it out componentRenderer is container dependent. What is the reason for having a additional method componentRenderer? What are the best practices for wiring magritte components together? The only way I found is to use onAnswer:. thanks in advance, Norbert

saving image and deployment features

by Martial Boniou

Hi, I am real interested in seaside/magritte/pier and as a newbie (in squeak but not in smalltalk) I would like to do a little Pier/seaside website. I chose to run my squeak process in a linux server with a framebuffer X server to administrate my image with VNC access (and not by the seaside inspector available with halos). I did it with a special user (not root) and my firewall connection configuration permits me to access externally to my webserver on standard port 80. But I am a bit unsecure with a deployment of a "classical" pier configuration. If my machine crash, I lost all my data. So I need to do backup. I can run a: SmalltalkImage current snapshot: true andQuit: false. but if a user does something on my website, it's rejected. So I read somewhere (maybe thru this mailing-list archive) about a way to do backup. Actually, I would like to save the image everytime it's possible. I heard about the use of: UnixProcess saveImageInBackgroundNicely but I don't know how to use it. With forkHeadlessSqueakAndDoThenQuit message, it seems to be possible to save my image in another until I do the permanent and tested weekly backup. So if I crash or there is a glitch, my image or the periodically save image can be broken but I can restore the most recent backup. If someone can explain me how to do (or find how to do) this, I'll be glad. I don't want to build a wiki/blog like site and lost in a crash all the readers'comments/posts. I also noticed some errors in the deployment of squeakfoundation.org. By clicking on 'Edit' or 'Login', there's error. But instead of permitting me to go back to the previous page with a short error message (and advertising the webadmin) like on the other classic php/jsp website, I go to debug message. It's really bad. I guess that when I click on 'Debug' I open a morph Debugger window on the squeak image. It's not what I (and probably the squeakfoundation.org webmaster) want. I am sure there is a way to shortcut the doesNotUnderstand message in seaside/pier so that in a deployment mode, the user has just a friendly error message and the webmaster received an email from squeak with the debug message infos and the context. So I need your help to try to develop a website with seaside/pier because I believe in those kind of way to develop websites (I like servlets too but it's ugly, heavy and I prefer smalltalk as I used smalltalk or ObjectiveC during the most important part of my life as a programmer). I thought that I just can develop component and toggle the deployment preference tag to true, to have a ready-to-use website but there are missing things. As I said before: + how to save in one or two temporary images without stopping the working pier site? and without going (as I do now) in config page (the only place when I said 'deployment' to false) to toggle halos and then to have an inspector which permits me to manually save (I know Lukas did so too but it's not a good way). There's database way too for persistence and I will probably look at Magma/REServe and something like that. I think there are smalltalk that can save multiimage (visualworks can do this I guess) and it could be a good option that squeak do that too. + how to build a beautiful debug messages to a secure and friendly deployment? The example of the squeakfoundation.org website is a horrible one. As with the 'Toggle Halos' button in the oops-i-didnt-see-i-toogle-deployment-to-false case, it's dangerous and every visitor can crash or browse in the image without getting the root seaside admin (that could be nd5 encrypted too). I hope you will have answers. Very thanks for reading this a-bit-too-long mail, -- Martial

Re: need help whith Magritte

by Lukas Renggli

Hi Christophe, > I make my model and view package. But now I am lost…how I can run > this… I see in your tutorial the line below to have seaside interface: > > result := self call: (aModel asComponent addValidatedForm; yourself). > > But I am block. This code looks ok and should work fine. The whole part within the brackets is Magritte, the rest is plain Seaside. So depending on why you are blocked, you might want to check out different resource: - If it is the Magritte part, you can read my master thesis [1] and or re-ask the question in the Pier, Magritte mailing list [2]. - If it is the Seaside part that poses the problem, you might want to check out my Seaside tutorials [3] or re-ask the question in the Seaside mailing list [4].

Re: RE: [Seaside] [Magritte] Multiple descriptions validation/condition

by Lukas Renggli

> Thanks, glad it's useful. As for beRequired, you got me there, no clue, > maybe someone else will chime in with the answer. The latest version of Magritte (Magritte-All-lr.179 or later) has properties to set the error text for specific error, e.g. #conflictErrorMessage:, #kindErrorMessage:, #multipleErrorsMessage:, #requiredErrorMessage: and #rangeErrorMessage:. The latest version of Pier also makes use of this new feature and now displays much nicer error messages. Note that you are required to load Seaside2.7 to use this version of Magritte. Hope this helps, Lukas -- Lukas Renggli http://www.lukas-renggli.ch

Re: Reuse of PierSecurity or Spielverderber without Pier in Seaside Application

by Philippe Marschall

2006/11/11, florent trolat <trolat.florent(a)laposte.net>: > Hi, > > I need, for my seaside application, security and authentification. > I've seen PierSecurity and Spielverder. This 2 packages will be very > usefull if I success tu use one without pier. > What's your feeling about this? > Do you think it's possible to reuse Spielverder without pier for example? > > maybe you know other security/authentification packages? I'm not really sure how much can be reused besides the general ideas behind it. I only know Spielverderber but I don't think the situation is much different for Lukas' package. The model makes the general assumption that we have commands that operate on a structure. There is a user class, a group class, some special group and user classes that you probably don't want and a command group class. Besides there is a list class, a list item class and some methods to find an item in the list. That was it, the rest is Pier specific. Philippe

Magritte Forms

by Ramon Leon

Anyone know if it's possible, to take descriptions from several objects and display them on the screen all at once? For example, say I have a Customer object with an addresses collection. But one data entry screen, I want to flatten it so that the first address in the collection shows up as fields on the customer form, but the model still keeps them as separate objects and each field still writes to it's original model. I looked through Lukas's thesis but didn't see anything. I was thinking I could override description on the instance side, and add All the subcomponents descriptors to the main description, but I don't see how it'd get bound to the subcomponent as it's model.

Magritte Validations

by Ramon Leon

Anyone know of any good resources for working with the validation system of Magritte. Specifically I'm interested in what it takes to have fields that depend on the value of each other. Say an end date that must be before a start date, both of which have just been edited. I was thinking something like this on the instance side... description ^self class description collect: [:each | each accessor selector = #eventEndDate ifTrue: [each addCondition: [:value | value > self eventStartDate]] ifFalse: [each]] But that doesn't work because I can't rely on eventStartDate having a value yet, it may not have been set by its description, or it may be invalid for some other reason. Are the any public sample apps that use Magritte heavily one could look at? Ramon Leon http://onsmalltalk.com
