Lukas, I've uncovered a small bug in MAReportComponent. While the #renderContentOn: method calls #labelId, that method is not implemented in the class hierarchy. I'm not sure if the implementation from MAElementComponent should be moved up, or if something else was intended for the report hierarchy. For reference, this is in package Magritte-Seaside-pmm.206. -- ============================================================ Thomas Koschate

HTML Attributes with custom renderers

by Norbert Hartl

Hi, I'm playing with custom views in Magritte. I have a model and overwrote descriptionContainer with my own instance of MAComponentRenderer. What I'm trying to achieve is to display a text input the following: <label for="anyid">labeltext</label> <input type="text" id="anyid"..../> As a quick test I changed the renderLabel: to renderLabel: aDescription aDescription hasLabel ifTrue: [ html label attributeAt: 'for' put: aDescription hash; with: [ html render: aDescription label ] ] I need an id attribute in the <input> tag which has the same content as the for attribute in the <label> tag. I don't have a glue how to insert an id attribute to the renderControl:. Is there a way to add an attribute if I only have a component. I doubt the component description is the right place to put. If I only want to change the behaviour of the text input field, is it best to overwrite the visitStringDescription? thanks in advance, Norbert

[ANN] Audioscrobbler Plugin for Pier

by Philippe Marschall

Hi There is now an audioscrobbler[1] plugin for Pier at [2]. Margitte is used for XML data binding. It makes use of traits so you will need a Squeak 3.9. And the YAXO XML parser. Currently supported are: * Top Artists * Top Albums * Top Tracks * Top Tags * Recent Tracks * Recent Banned Tracks * Recent Loved Tracks * Weekly Artist Chart * Weekly Album Chart * Weekly Track Chart The Audioscrobbler system is a database that tracks listening habits and calculates relationships and recommendations based on the music people listen to. A screenshot can be found at: http://img79.imageshack.us/img79/7537/audioscrobblervp6.png [1] http://www.audioscrobbler.net/ [2] http://mc.lukas-renggli.ch/audioscrobbler/ Cheers Philippe

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

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.
