Rails 3 Nested Forms with datamapper
- by jens freudenau
i have two models:
class MeetingPoint
include DataMapper::Resource
belongs_to :profile
property :id, Serial
property :lat, String
end
and
class Profile
include DataMapper::Resource
has n, :meeting_points
property :id, Serial
property :distance, Text
property :created_at, DateTime
property :updated_at, DateTime
end
Now I create a form to edit the profile and the meeting_poing:
= form_for @profile do |f|
= f.text_field :distance
= f.fields_for :meeting_points do |ff|
= ff.text_field :lat
= f.submit
But when I want to save the values I get always the error:
"undefined method `readonly?' for ["lat", "14.000"]:Array"
