Using fields from an association (has_many) model with formtastic in rails
- by pduersteler
I searched and tried a lot, but I can't accomplish it as I want.. so here's my problem.
class Moving < ActiveRecord::Base
has_many :movingresources, :dependent => :destroy
has_many :resources, :through => :movingresources
end
class Movingresource < ActiveRecord::Base
belongs_to :moving
belongs_to :resource
end
class Resource < ActiveRecord::Base
has_many :movingresources
has_many :movings, :through => :movingresources
end
Movingresources contains additional fields, like "quantity". We're working on the views for 'bill'. Thanks to formtastic to simplify the whole relationship thing by just writing
<%= form.input :workers, :as => :check_boxes %>
and i get a real nice checkbox list. But what I haven't found out so far is: How can i use the additional fields from 'movingresource', next or under each checkbox my desired fields from that model?
I saw different approaches, mainly with manually looping through an array of objects and creating the appropriate forms, using :for in a form.inputs part, or not. But none of those solutions were clean (e.g. worked for the edit view but not for new because the required objects were not built or generated and generating them caused a mess).
I want to know your solutions for this! :-)
