Rails - Jul 2006 - partial_counter

Hi,

i was wondering if there was any conventional way to find out (via the 
partialname_counter, or any other way) which partial is the last in a 
set of partials ( render :partial => ''name'', :collection
=>
''@somethings'') so that i can display some kind of variable in
the last
partial.

there''s got to be some neat way to do this?
(like setting :locals => {:abc => @var} if partialname_counter == LAST)
thanks,

s

Shai -

  Interesting Idea.

  If its a display issue then would displaying it after the loop calling the
collection of partials be acceptible?

  Example:
# in controller
render :action => ''list''

# in list.rhtml
<%= render :partial => ''mypartial'', :collection =>
@mypartials %>
<%= display_cool_stuff_for( @var ) -%>

  ---------------------

If its a data issue then I suppose the following might work.

# in list.rhtml
<% @mypartials.each_with_index do | part, ii | %>
  <% if ii + 1 == @mypartials.size %>
    <%= render :partial => ''mypartial'', :locals=> {
:mypartial => part,
:other => @var } %>
  <% else %>
    <%= render :partial => ''mypartial'', :locals => {
:mypartial => part } %>
  <% end %>
<% end %>

 ------------------------

Hi travis,

''tis an interesting idea; i was actually visualizing some kind of rails
magic (like partialname_counter.last) to do the above, instead of 
defining a each_with_index on an array of partials...
i already got the solution done by passing:

<%= render :partial => ''object'', :collection =>
@objects, :locals =>
@objects%>

and then, in the partial itself i put my variable
<% if object == @objects.last %>..@var..<% end %>
which worked fine...i was just hoping to see if there was some kind of 
rails method for doing this when calling a collection of partials that 
could be inserted in the _partial.rhtml

either way, thanks for the speedy reply,
and regards back 2 u,

shai
