D2W: Grouping fields in edit form

Posted on by david

To group your edit form fields use sectionsContents instead of displayPropertyKeys. A rule for a User for might look like this:

LH: pageConfiguration = 'EditUser'
RH: sectionsContents =
(
  (
    "Personal Info",
    "salutation", 
    "firstName", 
    "lastName", 
    "emailAddress", 
    "phone", 
    "phoneExtension", 
    "mobile"), 
  (	
    "Address", 
    "address.address1", 
    "address.address2", 
    "address.city", 
    "address.province", 
    "address.postalCode"), 
  (	
    "Details", 
    "organization", 
    "role", 
    "loginCredential.password", 
    "loginCredential.isActive", 
    "loginCredential.role"
  )
)

This will result in a form that looks something like this:

Standard assumptions apply: Wonder’s D2W classes are being used.

D2W: List default sort order

Posted on by david

Assumptions: Your D2WList page inherits from ERD2WListPage in Wonder (and if it doesn’t it should).

Apply a default sort order on the list with a rule that looks like this:

LH: task = 'list' and entity.name = 'User'
RH: defaultSortOrdering = ( "name",
"compareAscending" )

Class: com.webobjects.directtoweb.Assignment

Also available are:

compareAscending
compareCaseInsensitiveAscending
compareCaseInsensitiveDescending
compareDescending.

Interesting stuff post

A couple of interesting bits and pieces today:

Blueprint is a CSS frameworks for making grid based web page layout much easier. It incorporates a decent reset.css (to clear all of the default rules set by the various browsers giving you a clean slate) then adds a grid.css and typography.css to give you a consistent base to start with.

I’m not much of a designer, and hacking CSS is fun, but only until it stops being fun (if that makes any sense). Anyway, this looks like a very promising start at making the fun bit last longer.

Via the Daring Fireball linked list.

ERAttachment is an addition to Project Wonder that provides a consistent mechanism for handling file attachments to web apps built in WebObjects. From the javadoc:

The framework provide a single unified set of components and models that can allow the storage of attachments on your local filesystem, served through your webserver; on your local filesystem served through a custom request handler; in your database, served through a custom request handler; and on Amazon’s S3 service, served directly from S3.

I’ve had to handle this kind of thing in a number of apps, allowing users to upload files and serve them back again. Very cool to see this make it into Wonder.
