Question

Im working with a medium sized Rails application and I do this in every controller:

def create
  @object = Model.new(params[:model].merge(editing_user: current_user))
  ...
end

def update
  @object = Model.find(params[:id])
  @object.editing_user = current_user
  ...
end

Setting the editing user over and over again is not DRY. I thought about cleaning this up with an observer but it would need access to the current user. Observers do not have access to the current user, neither should they (Law of Demeter).

Any suggestions how to DRY this up between controllers?

Answer 1

class ApplicationController < ActionController::Base
  before_filter :init_request

  def init_request
    params[:editing_user] = current_user
  end
end
