I am attempting to do this:
<% if not @session.nil? %><%=
@session[''user''][''firstname''] +
"''s" %><%
end %>
I know there is a better way of writing it, but my brain won''t work it
out.
When I do this
<h1>Listing <%= if not @session.nil?
@session[''user''][''firstname''] +
"''s" %> bookmarks</h1>
I get:
|compile error
(erb):3: syntax error
_erbout.concat "<h1>Listing "; _erbout.concat(( if not
@session.nil? @session[''user''][''firstname'']
+ "''s" ).to_s); _erbout.concat "
bookmarks</h1>\n"
^|
Cheers
Geoff

Try this: <%= @session[''user''][''firstname''] + "''s" if @session %> nil counts as false anything else is true so this simply looks for the @session to be there. -Nick On 10/15/05, Geoff <geoff-hL7hnT9RFJ9RuSCTpLpCrg@public.gmane.org> wrote:> I am attempting to do this: > <% if not @session.nil? %><%= @session[''user''][''firstname''] + "''s" %><% end > %> > > I know there is a better way of writing it, but my brain won''t work it out. > > When I do this > <h1>Listing <%= if not @session.nil? @session[''user''][''firstname''] + "''s" > %> bookmarks</h1> > I get: > compile error > (erb):3: syntax error > _erbout.concat "<h1>Listing "; _erbout.concat(( if not @session.nil? > @session[''user''][''firstname''] + "''s" ).to_s); _erbout.concat " > bookmarks</h1>\n" > ^ > > > Cheers > > > Geoff > > > > _______________________________________________ > Rails mailing list > Rails-1W37MKcQCpIf0INCOvqR/iCwEArCW2h5@public.gmane.org > http://lists.rubyonrails.org/mailman/listinfo/rails > > >

neat, but not as readable IMO On 10/15/05, Geoff <geoff-hL7hnT9RFJ9RuSCTpLpCrg@public.gmane.org> wrote:> Oooh, I like that one. > > Thanks > > Geoff > > Ezra Zygmuntowicz wrote: > > > > > On Oct 15, 2005, at 11:45 AM, Geoff wrote: > > > >> I am attempting to do this: > >> <% if not @session.nil? %><%= @session[''user''][''firstname''] + "''s" % > >> ><% end %> > >> > >> I know there is a better way of writing it, but my brain won''t work > >> it out. > >> > >> When I do this > >> <h1>Listing <%= if not @session.nil? @session[''user''][''firstname''] + > >> "''s" %> bookmarks</h1> > >> I get: > >> > > > > Try this one on for size: > > > > <%= @session[''user''][''firstname''] + "''s" rescue nil %> > > > > Cheers- > > > > -Ezra Zygmuntowicz > > WebMaster > > Yakima Herald-Republic Newspaper > > ezra-gdxLOakOTQ9oetBuM9ipNAC/G2K4zDHf@public.gmane.org > > 509-577-7732 > > _______________________________________________ > > Rails mailing list > > Rails-1W37MKcQCpIf0INCOvqR/iCwEArCW2h5@public.gmane.org > > http://lists.rubyonrails.org/mailman/listinfo/rails > > > _______________________________________________ > Rails mailing list > Rails-1W37MKcQCpIf0INCOvqR/iCwEArCW2h5@public.gmane.org > http://lists.rubyonrails.org/mailman/listinfo/rails >
