Rails - Jul 2006 - setting initial text field values in a form

Hi,

I am trying to create a basic form in which I want one of the fields 
initialized before displaying it.

My code (in a view) is as follows:

<%
  if ( session[:user_id] != nil  )
  then
    logged_in_user = User.find(session[:user_id])
  end
%>

<% form_for :suggestion do |form| %>

<label for="suggestion_title">Topic:</label><br/>
<%= form.text_field :title, :size => 64 %>
<label for="suggestion_email">Email:</label><br/>
<%= form.text_field :email, :size => 64 %>
<label
for="suggestion_suggestion">Suggestion:</label><br/>
<%= form.text_area :suggestion, :size => 1000, :cols => 48 %>
<%= submit_tag "Send Feedback", :name=>"addsuggestion"
%>
<% end %>

I would like to set the email address in the form field such that it 
displays the email address from the logged_in_user (i.e., 
logged_in_user.email) any ideas on how to do this would be appreciated.

I have tried multiple times using things such as
:suggestion.email = logged_in_user.email
:email = logged_in_user.email

appreciate the input

+1 slap on the wrist for putting business logic in a view....

However, a better way to do this is

-- controller

def action
  @suggestion = Suggestion.new
  @suggestion.email = User.find(session[:user_id]).email
end

-- view

<%= text_field ''suggestion'', ''email''
%>

If you initialize the object with default values in the action, you will  
see them in the view when it renders.
