Hi all,
I''d like to move some view code to a helper but it doesn''t
work because
I need to render two partials each time.
Q: Is it possible to do this with a helper?
Example:
-----------------
Before: In the view:
...
<% case controller.controller_name
when ''member'' %>
<%= render :partial => ''shared/member_menu'' %>
<%= render :partial => ''shared/member_submenu'' %>
..
<% end %>
...
After: In the view:
<%= generate_menu %>
After: in application_helper.rb (DOESN''T WORK)
def generate_menu
case controller.controller_name
when ''member''
render :partial => ''shared/member_menu''
<--- HAS NO
EFFECT !!
render :partial => ''shared/member_submenu''
...
end
end
problem: the 1st ''render :partial'' has no effect

By default they will return the last evaluated line, in this case what your second render line returns. You can probably concatenate the two to a single return value. //jarkko -- Jarkko Laine http://jlaine.net http://odesign.fi -------------- next part -------------- A non-text attachment was scrubbed...

Of course, you''re right. What was I thinking?

Yes :
def generate_menu
case controller.controller_name
when ''member''
a = render :partial =>
''shared/members_avantages_menu''
b = render :partial =>
''shared/member_submenu''
a+b <<---- CONCATENATION
when ..
...
end
end
Thanks again for waking me up.
