Rails 3: create input field for each element of a collection (MongoID)

Hi all,

I have two models, Item and Bid

class Item

include Mongoid::Document
field :name, type: String
has_many :bids
end
class Bid
include Mongoid::Document
include Mongoid::Timestamps::Created
field :bid, type: Float
belongs_to :item
end

In views/prices/index I would like to list all items in a table and for
each item put a field next it in which people can enter a number. At the
bottom of the form should be a submit button for all records.

How is this best achieved?
There’s plenty of code out there explaining how to add, for instance,
several
questions to one
surveyhttp://railscasts.com/episodes/196-nested-model-form-part-1but I
couldn’t find an example that shows how to add one new record for
each of of an existing element of a collection.

Thanks…
