DangerousAttributeError in OmniAuth Railscast Tutorial: create is defined by ActiveRecord

Question

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:

Answer 1

So just to finish the question off you will need to create a migration using this command:

rails g migration remove_silly_authentication_fields_which_should_not_be_there

Which looks something like this:

class DropSillyControllerAttributes < ActiveRecord::Migration
   def change
      remove_column :authentications, :index
      remove_column :authentications, :create
      remove_column :authentications, :destroy
   end
end

And run it using the usual:

rake db:migration

Or alternatively you should be able to run:

rake db:rollback

To roll back the changes just made to the database and:

rails d scaffold authentication

To remove all the files, then run:

rails g scaffold authentication user_id:integer provider:string uid:string

And do the other stuff manually

I did exactly the same thing myself by the way.
