What is OpenID?
OpenID is an Internet-wide identity system that allows you to sign in to many websites with a single account.
With OpenID, your ID becomes a URL (e.g. http://username.myopenid.com/). You can get a free OpenID for example from myopenid.com.
For more information visit the official OpenID site.

A question about DataObjectDecorators
17 July 2007 at 4:21am
For OpenID support I implemented a DataObjectDecorator, but I couldn't figure out how I can add a custom validator to it.
I need to ensure that the entered OpenID is unique so that only one user account is linked to a specific OpenID. Is that somehow possible?
The only way I know about is to use the augmentDatabase() method to add an unique-index to the database (adding it to extraDBFields() 'indexes' doesn't work) but in that way I can't output an error-message.
Does someone know how this can be solved?
Thanks a lot,
Markus -

Arg, this is a bug. I forgot to includes indexes on the list of You'll need to fix DataObjectDecorator::loadExtraDBFields()
There's a list of the static variables that are updated; just add indexes to this list.

OK, I fixed it in r38854 (and added also defaults to it). But this doesn't help to solve my problem
Now I can prevent that duplicate entries are created, but no error message will be shown since an database error occurs.. is there any way to implement a validator for DataObjectDecorators or handle such database errors ("Duplicate entry 'http://markus-lanthaler.myopenid.com/' for key 2")?

Are there any news on this? How can I implement a validator on a DataObjectDecorator??

OK, I fixed that in r40925 (also for the forum module: GSoC branch r40926).
It's not the best (scalable) solution but it works for the moment and Hayden said that I should not change the core's validation behavior at the moment.
