Well other than saying that you are calling render from somewhere that  
you shouldn’t there’s not a lot more to be said without seeing what  
you have done.

ok This my module which in lib folder  
module Rakelimit  
def self.included(controller)

```
    controller.extend(ClassMethods)

   end

   module ClassMethods

    def acts_as_rakelimit
         ip = request.remote_ip
        puts ip = local_ip
       minute= (Time.now.to_i / 60).to_i
        checks = Ipcheck.find(:first, :conditions =>[ "ipaddress = ?

```

and time\_min =?", ip,minute] )  
puts checks.inspect  
if checks == nil

Ipcheck.create!(:ipaddress=\>ip,:time\_min=\>minute,:ip\_count=\>1)  
else  
checks.increment(:ip\_count,1).save  
if checks.ip\_count \>3

```
                render_404

       end
        end
    end

     def render_404
           render :file =>"#{RAILS_ROOT}/public/404.html", :status 

```

=\>  
“404 Not Found”

```
         return false
     end

```

it’s for susbend the process when the person trying more then 3 time if  
it  
increased more then 3 then i would like render 404 error

These shouldn’t be class methods. This is all about dealing with an  
individual request, which only makes sense in the context of an  
instance method
