Question

class Project < ActiveRecord::Base
  has_many :pages
  attr_accessible :name, :class_name, :content, :style

  def bulk_update_pages(attributes)
    for a in attributes do
      pages.find(a['id'].to_i).update_attributes(a) if pages.exists?(a['id'])
    end
  end

end

class Page < ActiveRecord::Base
  belongs_to :project
end

Is it a good way to bulk update pages from project ? Project.find(session[:ProjectId]).bulk_update_pages(params)

I think you’d be better off using a nested form:
