As far as I understand your question you need to use the params hash- like object. -- Thanks, Ivan Povalyukhin On Jan 2, 11:08 am, "Jose tomas R." <li...-fsXkhYbjdPsEEoCn2XhGlw@public.gmane.org> wrote:> how could i get a value from previus page? > for example > > on EVENT show view i have > > <%= link_to ''New Message'', new_message_path( :event_id => @event.id) %> > | > > and i need to get the event id on the new_message page to send it when > creating the message > > -- > Posted viahttp://www.ruby-forum.com/.-- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

The parameters passed are then available in the params hash. So your :order variable should be available as params[:order]. I suggest you run through some tutorials to get an understanding of basic Rails operation. The one at railstutorial.org (available free online) is good. Also have a look at the Rails Guides.

However that is a horrible way to do it. Firstly a small point, the variable @order can just be order, unless you want the variable to be accessible in the view. Secondly, however, imagine what would happen if someone sends an http request with an SQL snippet in :order. That will get inserted into the SQL of the find and could wreck your database. A better way would be to test the value of params[:order] for a set of valid values and use the appropriate order setting in the call to paginate.
