text_field value doubt

<%= f.text_field :item, :value => Date.today %>
above code displays todays date in item text field.

I want to display the parameter thr(search string)..somthin lik
<%= f.text_field :item, :value => params[:search_string] %>
but above code does not work.

Textfield is blank and no param value is printed. why? plz help.

Btw the search_string(param) was entered thru a textField that was in a
different view page. do we have to pass it to this 'creteForm' view
page. if yes,how to do it?

Have a look at the Getting Started guide at
http://guides.rubyonrails.org/. It will show you how to setup an @
variable in the controller to display in the view.

Also have a look at the guide on debugging so that you see how to
break into your code and inspect variables to see what is going on
when it does not work.
