i'm guessing you are talking about app/models/user.rb file. you don't need to have attr_accessible followed by attributes there no more if you are using Rails 4. in fact, if you type in the attributes, you'll get this error message:

attr_accessible is extracted out of Rails into a gem. Please use new recommended protection model for params(strong_parameters) or add protected_attributes to your Gemfile to use old one.

basically, define a private method in the controller that takes the params hash. see an example here: https://github.com/rails/strong_parameters

So after searching a lot i realised that the .rb files that were being generated in the project were missing this. (probably only in the present latest version of rails)

attr_accessible :email, :password, :password_confirmation, :remember_me, :first_name, :last_name, :profile_name

So basically these have to be manually added by us which is quite tedious. Is there any workaround?
