This is great and helped me a lot!

I ran into one issue with this part:

collection_action :send_invitation, :method => :post do
  @user = User.invite!(permitted_params[:user], current_user)
  if @user.errors.empty?
    flash[:success] = "User has been successfully invited." 
    redirect_to admin_users_path
  else
    messages = @user.errors.full_messages.map { |msg| msg }.join
    flash[:error] = "Error: " + messages
    redirect_to new_invitation_admin_users_path
  end
end

@user.errors.empty? will probably almost never be true after User.invite! since it skips validations. If you do want to have some validations in the Admin form you can make the blank User with new and call a custom validation method on it before the if. Then if it passes you can save and invite the User.

@user = User.new(permitted_params[:user].merge(invited_by: current_user)
@user.valid_to_invite
if @user.errors.empty?
  @user.save(validate: false)
  @user.deliver_invitation

I'm glad a 7 year old gist is still valuable, and appreciate the feedback, @jelaniwoods @storrence88 et al!
