h() method in form partial

Hi
   I have a doubt. Dont know it is valid. Just asking. I am trying to
reuse the same partial _form for both new and edit. So from new.html.erb
I call partial like

<%= render :partial => 'user_fields', :locals => {:f => f}%>

and in _user_fields.html.erb an example field as

<p>
      <%= u.label :first_name,'First Name' %>
      <%= u.text_field :first_name,:maxlength => 50 %>
</p>

      My question is if I call this same partial in edit.html.erb also,
how can I apply the h() method like below (since this fields being
populated with value from db being an edit form)

<p>
      <%=h u.label :first_name,'First Name' %>
      <%=h u.text_field :first_name,:maxlength => 50 %>
</p>

Thanks in advance
Tom

I'm pretty sure the text_field method will cover that for you - you
wouldn't want to put the h where you have there or you'd end up escaping
the actual <input type="text" /> field.

If you really wanted to override the value then you could do something
like this:

<%= u.text_field :first_name, :value => h(your_value) %>

Well it is valid but not useful - The label help would generate
something like

<label for='first_name>First Name</label>

But then h comes along and escapes the whole lot (not just the label
contents) - try it for yourself!
