Rails - Jul 2006 - Can''t get observe_field to take a variable for a field name

The subject pretty much says it all: I can''t?get observe_field to take
a
variable for a field name

I''ve tried:

<%= observe_field(var_name, ...
<%= observe_field("#{var_name}", ...
<%= observe_field(:"#{var_name}", ...

No luck.

Am I missing something?

Thanks,

: )

Just went through this myself, so I feel your pain ;-)  It''ll work if
your
observe_field and the field you''re observing are in a partial and you
pass
the variable in as a local.  I''ve included the my code below.

hth,
Bill

----  edit.rhtml (in part)  ----
<%= render :partial => ''std_surgery_div'',
                   :locals => {:surgery_name => name_underscored,
                                     :display_name => display_label,
                                     :checkbox_name => box_name,
                                     :datefield_name => field_name,
                                     :numeric_value => numeric_value,
                                     :checked_value => checked_value,
                                     :date_exists => checked_value,
                                     :surgery_date => date} %>

---- _std_surgery_div.rhtml ----
<div id=<%= surgery_name %> >
<p><label><%= display_name %></label>
<%= check_box_tag(checkbox_name, numeric_value, checked_value) %>
<%= observe_field(checkbox_name, :url => {:action =>
''update_std'', :id =>
surgery_name}) %>

<% if date_exists == ''true'' %>
  Approx. Date:
  <%= text_field_tag(datefield_name, surgery_date, :size => 30) %>
  <%= observe_field(datefield_name, :url => {:action =>
''update_date'', :id
=> surgery_name}, :with => "sdate" ) %>
<% end %>
</p>
</div>
