Rails - Feb 2007 - Pass parameters in periodically_call_remote?

Hi,

I am still new to RoR, so please bear with this newbie question.  I
would like to have the application in view to press result back to the
controller when the periodically_call_remote is called.  Right now,

this is the code in the view:

<div id="get_result"></div>
<%= periodically_call_remote(:update => ''get_result'',
                                        :url => { :action =>
"getlog" },
                                        :frequency => 2 );
%>


this is the code in the controller

def getlog
  userid = params[:user_id]
  if (userid == "1")
    render :text => "Here"
  else
    render :text => "There"
  end
end

I tried periodically_call_remote(:update => ''get_result'',
:url => {
:action => "getlog", :user_id = "1" }, :frequency => 2
), but it would
not work

Are you sure?  periodically_call_remote is typically used to fetch a value 
from the controller to pass back to the view.  It sounds like you''re
wanting
(maybe in the next iteration of your code) to pass a user-entered value back 
to the controller.  If that''s the case, then you''ll want to
use
observe_field.

To answer the question you asked, though ...

:url => { :action => "getlog", :user_id =>
''1''}

hth,
Bill

Thanks.  I will look into observ_field.
