Hi, How do I get a value out of a form block eg. <% form_for :order do |form_block| %> <%= form_block.text_field :name, :size => 40 %> <% end %> If within that block I wanted to get the value of an attribute like age, how cold you get that from the form_block instance? eg form_block.age (i realise this does not work). I could just do @order.age but I need to check from a helper where the block is only sen to it.

I think, you trying to implement something like observe field on name
to get age.
You can
<%= observe_field ''order_name'',
:frequency => 1,
:update => "UPDATE_SPAN/DIV/TEXTFIELD_ID_OF_AGE",
:url => {:action => ''YOUR_ACTION_TO_GET_AGE
''}%>
For more info on this ajax, refer this:

Hi Carolene, Unfortunately, I have not explained myself properly... Great answer though! What I meant is:- <% form_for :order do |form_block| %> <%= form_block.text_field :name, :size => 40 %> <% some code here that could return the value of age that refers to age via form_block (not @order) eg form_block.age %> <% end %> On Aug 13, 5:18 pm, Carolene <kiran.sou...-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> wrote:> I think, you trying to implement something like observe field on name > to get age. > You can > <%= observe_field ''order_name'', > :frequency => 1, > :update => "UPDATE_SPAN/DIV/TEXTFIELD_ID_OF_AGE", > :url => {:action => ''YOUR_ACTION_TO_GET_AGE ''}%> > > For more info on this ajax, refer this:http://wiki.rubyonrails.org/rails/pages/observe_field+-+Passing+Param... > > Regards. > > On Aug 13, 11:52 am, "nigel.bris" <nigel.b...-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> wrote: > > > Hi, > > > How do I get a value out of a form block > > eg. > > <% form_for :order do |form_block| %> > > <%= form_block.text_field :name, :size => 40 %> > > <% end %> > > > If within that block I wanted to get the value of an attribute like > > age, how cold you get that from the form_block instance? eg > > form_block.age (i realise this does not work).

I might be wrong about the edge/non-edge distinction; it''s based on some quick trials, where <%debug f.object %> got me nil in non-edge.
