def self.current
    Thread.current[:skr_user_proxy]
end

.current_id ⇒ Fixnum

Retrieve the current id of the user we’re proxying for. get’s a bit complicated since we can proxy both for a user object or just the user’s id

Returns:

  • (Fixnum) —

    current user’s ID. If the current user is not set, returns 0

def self.current_id
    if self.current.nil?
        0

    end
end

.scoped_to(user) ⇒ UserProxy

sets the user for the duration of the block

Examples:

Inside a Rails controller


class DocumentsController < ApplicationController
    around_filter :set_skr_user

    # update's the Document's owner to current
    # But sets all the notes to be owned by admin
    def update_owner
        doc = Document.find(params[:id])
        doc.current_owner = Skr::UserProxy.current
        Skr::UserProxy.scoped_to( User.admin ) do
            doc.notes.each{ |note| note.set_owner_to_current! } # will set to Skr::UserProxy.current
        end
    end

    private

    def set_skr_user
        user = SuperUserModel.find( session[:user] )
        Skr::UserProxy.scoped_to( user ) do
