Re: [RDBO] Integration with Rose::HTML::Form

id is in $session, which the form knows nothing about. But in most

applicable data like the session, in which case it's reasonable for
customer_from_form() to return you an object that's completely ready
to be save()d, without any fiddling, and, ideally, without need for an
explicit update = ... argument.
This is a question I have for some time now: How to get your framework object
into the depth of
all the RDBO and RHTMLO objects (DB table/manager, HTML forms, special fields).
I use
CGI::Application as my framework and Template Toolkit as my templating engine
and it is so
helpful to have the CGI::Application object within the template as 'c'. So I
can just say
c.session.param('something'). Thanks Cees!
Are there any similar solutions out there for the Rose family of Objects? E.g.
I need something to
list the dates of the currently logged in user. At the moment I have to
explicitely pass the
CGI::Application object (or the id of the user). It would be so helpful if it
was already there
somehow.
Cheers,
Michael

I don't use CGI::Application, so maybe I'm misunderstanding how it works,
but how about a class method that returns the current CGI::Application
object? e.g., MyWebSite-current_app(). You'd set it at the beginning of
each request. Then, in your common RDBO base class, just add a method:
sub app { MyWebSite-current_app }
and now you can get at it from any RDBO object.

Yes, I will try this but I was hoping for some import hack that would do this
for me by just 'use'-ing
a plugin module. Then I wouldn't have to do it again for every app in every
(base) class and I don't
have base classes for everything yet.
But anyway I think this is a good start.
Thanks,
Michael
