After scouring through the group I found several older posts on how to
make this work properly, not sure if it's documented elsewhere so I'll
put it all here for completeness.
For a Hobo 1.3 application where you want to use an enum-string to
populate a <filter-menu>, you must do the following (using the Agility
project story model with status filtering as an example):
In the model ...
class Story < ActiveRecord::Base
hobo_model # Don't put anything above this
Status =
HoboFields::Types::EnumString.for(:new, :accepted, :discussion, :implementation)
fields do
title :string
body :text
status Story::Status
timestamps
end
...
In the controller, setup the filter:
class StoriesController < ApplicationController
hobo_model_controller
auto_actions :all
def index
hobo_index Story.apply_scopes(:status_is => params[:status])
end
...
And finally at the view layer (index.dryml for my case) ...
...
<append-header:>
<div class="filter">
Display stories by status: <filter-menu param-name="status"
options="&Story::Status.values"/>
</div>
</append-header:>
...
I hope that this helps someone else out there. It would be beneficial
in my mind to add this to the Agility tutorial, or perhaps it's
already well documented and I just looked in the wrong places :-)
