ruby - How to stop only one user, say with id=22 from from create/update methods in rails? -

i using devise , have

before_filter :authenticate_user!  

on resource page, pages can created/updated registered user don't want specific user, :id = 22 not have thls. how ?

for example update code on pagecontroller

@page = page.find(params[:id]) 

so want make

if user.id != 22     @page = page.find(params[:id]) 

you may in pages controller by

if current_user , current_user.id != 22   ... 

or before_filter in pages controller by

before_filter :check_for_specific_user, :only => [:create, :update]  def check_for_specific_user   if current_user , current_user.id == 22     # redirect or   end end 

or may in application controller by

before_filter :check_for_specific_user  def check_for_specific_user   if params[:controller] == 'pages' , ['create', 'update'].include? params[:action] , current_user , current_user.id == 22     # redirect or   end end 

also idea have method in application controller like

def admin?   current_user , current_user.id == 22 end 

then in pages controller able write just

if admin?   # ... end
