addCondition:labelled:


addCondition:labelled does not seem to be working the way I expected.

I just want to validate that a given text field is not empty

I have a description definition method and setter:

descriptionTags
^MAStringDescription new
    selectorAccessor: #tagsConverter;
    label: 'Tags';
    priority: 40;
    addCondition: [:value | value notEmpty ]
        labelled: 'Please provide at least one tag';
    yourself

tagsConverter: aString
    tags := aString asUppercase subStrings asSet

On submit, I get an error that nil does not understand asUppercase. Shouldn't the condition fail before the setter is called? I've tried [ :value | value notNil ], and beRequired as well, got the same error. I also tried to change the initialize method of the object I'm describing to set tags to an empty collection but that didn't work either.

Thanks,
Joel

a question about pier syntax

Let me forward this to the pier list since it's a syntax related  
question.

Re: addCondition:labelled:

> I just want to validate that a given text field is not empty

Normally sending #beRequired to the description should be enough. At
least with my Seaside forms this works well and there is no need to
add an additional check for #isEmpty.

> On submit, I get an error that nil does not understand asUppercase.
> Shouldn't the condition fail before the setter is called?

#beRequired ensures that a nil or empty value is not committed.
Additional conditions will not be evaluated (there are various
examples of this in Pier, for example).

Cheers,
Lukas

Ultra-newbie question

I have used Squeak, and I have used Seaside, but it has been a while.

I have brought up the Pier environment on a headless server, and it  
looks as if I probably have the ability to configure it, add to it,  
etc.  But there does not appear to be any documentation for Pier that  
is aimed at those who have forgotten what they may ever have learned  
about Seaside.  I'm going back over the Seaside tutorial, but I  
wonder if someone can tell me how to log in to the default Pier  
server, the one that comes up when you make minimal changes out of  
the box (not even running under Apache).  I had a "Log in" link on  
the page at one point, made the attempt with no errors reported, and  
was unable to edit anything.  I think I'm missing a major concept  
somehow.

Can anyone suggest what major item I've probably forgotten about  
Seaside?

Thanks.

GC

The default username/password of Pier is admin/pier.

The default username/password of Seaside is admin/seaside.

The basics on Pier are documented here: http://www.piercms.com/doc.

Let us know if you have further questions.

I modified it a bit to use lightbox.
See http://www.impro-v-istres.fr/seaside/pier/photos/picasa for an
example of how it looks.
The code is on http://www.squeaksource.com/PicasaClientLightbox/

Thanks very much.  I'll try to make at least marginal sense.

I want to make a random change on the page, for no other reason than
to see that I can have some effect.  So, the way to do that is... Turn
on Halos, I think, and then... OK, in a halo there are icons for Class
Browser, Object Inspector, and CSS Style Editor.  And also a pair of
letters, R-ender and S-ource.  I can edit the behavior of classes, but
if I want to change the color of one of the text objects, how do I do
that?  If I want to change the text itself, how do I do that?

OK, hard things are easy and easy things are hard.  The tools seem to
address issues of much greater complexity than I'm able to think about
yet.  And I don't see the corresponding tools for doing anything
dead simple.  And I have a feeling I'm staring blindly right at it.

Seaside manual maybe?  Any section in particular?  What I'm trying to
do should be the easy stuff, I would have thought.

I thank you in advance for your help.

After you are logged in, commands show up on the bottom of the page. (Where the Login link was, NOT the halos toolbar)

Click "Edit" to edit the page.
Click "Remove" to remove it.
Click "Add" to add a sub-page or a file or one of the many components available.
Click "Edit design" to change the CSS or the layout of the page structure.
Play with it, don't be afraid. the thing to understand is that you are not really writing any seaside code at this point. You are managing content.

Sure, OK, that's exactly what I want to do.  I had to stumble a bit more, apparently.  I appreciate your patience.

Two questions.
 1. If I click the Class Browser button, then I *am* modifying code, right?  I mean, I can make changes to class behavior of, ... the Pier classes?

 2. When I clicked Edit, I could totally go to town on the "Welcome to Pier!" block of text.  I still haven't worked out how to affect the "What's new" block.

Hope this helped
John


Yes indeed.  Thanks.

Re: Picasa client for Pier

hi Nicolas,


that's really cool but why didn't you publish it as a new version of the same project?

Cheers,
Cip
