Unpermitted Parameters adding new fields to Devise in rails 4.0

Question

Very new to working with rails. I have implemented a basic login system using Devise. I am trying to add a couple of new fields (bio:string, name:string) into the sign_up pa

Answer 1

The problem seems with the strong parameters, look here and copy the code.

https://github.com/plataformatec/devise/blob/rails4/app/controllers/devise/registrations_controller.rb

Copy that file to the same location in your project app/controllers/devise/registrations_controller.rb

and change the code of the create action

# POST /resource
def create
  # THIS LINE IS THE ONE YOU CHANGE
  self.resource = build_resource(sign_up_params.merge(:bio, :name))

  if resource.save
    if resource.active_for_authentication?
      set_flash_message :notice, :signed_up if is_navigational_format?
      sign_up(resource_name, resource)
      respond_with resource, :location => after_sign_up_path_for(resource)
    else
      set_flash_message :notice, :"signed_up_but_#{resource.inactive_message}" if is_navigational_format?
      expire_session_data_after_sign_in!
      respond_with resource, :location => after_inactive_sign_up_path_for(resource)
    end
  else
    clean_up_passwords resource
    respond_with resource
  end
end

I must tell you that Iam not pretty sure if this works because I don't use devise but seeing the code it seems it will work.
