Dynamic attributes with Rails and Mongoid

Question

I\'m learning MongoDB through the Mongoid Ruby gem with Rails (Rails 3 beta 3), and I\'m trying to come up with a way to create dynamic attributes on a model based on fields

Answer 1

Be sure to set allow_dynamic_fields: true in mongoid.yml. Example:

defaults: &defaults
  allow_dynamic_fields: true
  parameterize_keys: true
  persist_in_safe_mode: true
  raise_not_found_error: true
  reconnect_time: 3
  use_object_ids: false

development:
  <<: *defaults
