Something like this worked for me:

def initialize(user)
    allow :home, :index
allow "devise/sessions", [:new, :create]
    allow "devise/registrations", [:new, :create, :destroy]      
    allow_param :user, [:name, :email, :password, :password_confirmation, :remember_me]
if user
        allow "devise/registrations", [:edit, :update, :cancel]
        allow "devise/sessions", [:destroy]
allow_all if user.admin?

Hope this helps


How is it possible to use that with nested attributes (forms). I have my models defined as follows:

class Timesheet < ActiveRecord::Base
  belongs_to :user
  has_many :activities, dependent: :destroy, inverse_of: :timesheet
  has_many :time_entries, through: :activities
  accepts_nested_attributes_for :activities, allow_destroy: true

class Activity < ActiveRecord::Base
  belongs_to :timesheet, inverse_of: :activities
  belongs_to :task
  has_many :time_entries, order: :workdate, dependent: :destroy, inverse_of: :activity
  accepts_nested_attributes_for :time_entries, allow_destroy: true, reject_if: proc { |a| a[:worktime].blank? }

class TimeEntry < ActiveRecord::Base
  belongs_to :activity, :inverse_of => :time_entries
  validates :worktime, presence: true, inclusion: { in: [0.5, 1] }       
  validates_presence_of :activity     

Actually it does not work. As far I could see at Ryan's strong_parameters rails casts github, he managed to do that (not very dynamically as he said and only for one post). In my case I have 1 or more activity with 7 time_entries each. Any idea how to do that? Thank you.


Fails if there is more than one nested resource. In my case I have: Timesheet-> accepts_nested_attributes_for :activities, Activity -> accepts_nested_attributes_for :time_entries. In permission file I declared it as follows:

        allow_param :timesheet, [:status, :user_id, :start_date, :end_date] 
        allow_nested_param :timesheet, :activities_attributes, [:task_id]
        allow_nested_param :activity, :time_entries_attributes, [:workdate, :worktime]

Nevertheless, I always get the error that time_entries attributes is empty. Any idea ? Thanks and regards


I followed by letter the screencast tuto but got the below errors:

Solved. I don't know why after copy-paste it did not work but after creating the same project from scratch everything worked fine. Thanks!


Great episode, Ryan, Thanks a lot> I tried it on a Windows machine with some minore modifications(added some specific gem dependencies) and everything worked as needed. Then I copy-pasted the same project on a Linux (Ubuntu 10.04) PC, changed the dependencies in Gemfile for gem 'libnotify', :group => [:test, :development], and the guard fails after running the bundle and 'guard' commandes:

Any idea on that?
I'm on Rails 3.1. and use Ruby 1.9.2 p0 version.
Thanks a lot.
