I figured I'd update this post with the solution I worked my way to.
In my model, Manuscript.rb the relevant lines:
has_one :timeline
accepts_nested_attributes_for :timeline
In the ManuscriptsController, we need to setup a timeline object in the new
actions. Would also need to happen in update if there was no timeline on
load
def new
hobo_new
@manuscript.build_timeline
end
And finally, the piece of glue that makes this all work with Hobo:
<field-list fields="title, msid, status, article_type, coauthors,
primary_author, timeline.duration" param>
<timeline_duration-view:><input
name="manuscript[timeline_attributes][duration]"/></timeline_duration-view:>
</field-list>
(I'm sure this will get abstracted into its own tag as I progress through
the rest of my project). The name field must be called timeline_attributes
so that Rails knows to save it in a dependent model.
(accepts_nested_attributes_for creates the timeline_attributes=() method on
the model to make this all work).
As always, I'd love criticism, but if this actually looks correct and
proper, I'd be glad to write up a recipe for it.
