I\'ve looked at ActiveRecord::DangerousAttributeError and other similar threads on SO, but they don\'t address the same issue.
I\'m following the omniauth tutorial:
Try: current_user.authentications.create!
EDIT
So basically your problem was that you had columns in your table named the same as methods of the Modal class.
You can't have a column named create or destroy in your database.
Most likely it was a typo on your model/controller generation.
