"selected" in form.select

I have a search form in my navbar where a user can select in which area he wants to search. After clicking the submit-button the results get rendered but the previous selected area is no longer selected.

<%= form.select (:suchfeld,    [ ['Beschreibungen','description'],    ['Headlines','headline']] ) %>

I was able to re-fill the search-field wich the previous content doing the following:

<%= form.text_field    :suche,    :name => "suche",    :size => 25,    :value => params[:suche].gsub(' ','') %>

But how can I automatically add "selected" to a select-field to select the last selected item?

Thanx

The easiest way is to use the html attrs parameter, like this: <%= form.select (:suchfeld,

   [ ['Beschreibungen','description'],    ['Headlines','headline']]

, :selected => @varname

) %>

where "@varname" is the value that was selected before posting. That var would be set in the controller, probably when you are grabbing the post data.
