From the Ruby Noob Dept: Issue(s) with accepts_nested_attributes_for
27 Feb 2010
Finally took some time to jump in and refactor some nested forms at Thredded using Rails 2.3′s accepts_nested_attributes_for. Thanks to Ryan Bates’ screencasts on the topic it was fairly easy. A little code cleanup and everything worked as it should … other than one thing.
Can’t mass-assign these protected attributes
Noticed that error in my development logfiles after a particular form wasn’t being saved. A User class had some protected, and some not, attributes and until I added the Profile attributes to it, the nested form submitting a User and it’s associated Profile record would not save.
class User < ActiveRecord::Base has_one :profile accepts_nested_attributes_for :profile attr_accessible :login, :email, :password, :password_confirmation # ... end
Needed just the Profile attributes set as accessible and ready for mass assignment
class User < ActiveRecord::Base has_one :profile accepts_nested_attributes_for :profile attr_accessible :login, :email, :password, :password_confirmation, :profile_attributes # ... end
Another case where you need to know at all times where and if properties of your classes are locked down or not.
