Thanks, but that is not the problem. I know transitions well and its
"in my fingertips" so to speak.
However. I cannot use :params => [:comment], since comment is not a
part of the model. The comment field I want to show is an ad-hoc
field, a placeholder for the user to add a comment, which I can handle
in the block after the transition:
Something like:
transition :foo, { :work=> :work } , :params
=>[:comment], :available_to => :user do |record|
c = Comment.new
c.body = record.comment
record.comments << c
record.save!
end
In the :work state allow a transition that keeps state in :work, but
which allows the user to enter a comment that will be saved in a child-
relation of the model.
I *could* add a comment-field to the model and just use it to get the
form displayed and then never really use the field in the database,
but that *really* feels like a bad hack...
