How protect all fields against mass assignment in mongoid app

Question

I have added this fix https://gist.github.com/2382288 for protect all fields against mass assignment in mongoid app.

in my config/initializers/mongoid.rb I have added this fix:

module Mongoid
  module MassAssignmentSecurity
    extend ActiveSupport::Concern

    included do
      attr_accessible nil
    end
  end

  module Document
    include MassAssignmentSecurity
  end
end

My question is:

this fix completely protects your application against attacks mass assignment?

Or is recommended to add attr_accessible all the attributes in each model?

Answer 1

This will make all Mongoid::Documents by default accept no fields to mass-assignment. This is probably not exactly what you want, as you will not be able to @model.update(params[:model)

You'll almost certainly want to go into the document and add:

attr_accessible :first_name, :last_name
