Hi, Keith
you missed my second email (sent immediately after ther first) where I
warned about the parenthesys that needed to be moved. Or, better, remove the
parenthesys, and just write:
<%= link_to 'Destroy', {:action => 'destroy', id => @album.id},
:confirm => 'Are you
sure?',
:method => :delete %>
This SHOULD work, without changing anything in the routes.rb file. However,
allow me to point this important point:
a) you have the routes.rb configured for REST, but you are not using the
Rest style Urls.
b) You could delete the line map.resources :albums, if for some reason you
do not want the RESTful Urls, as at a certain moment there will be
confusion; or perhaps invert the order of the rules in routes.rb, as
suggested by the forum post (although I would delete, for more clarity).
On the other hand, if you wanted to to begin use the Rest routes (standard
in Rails since 2007), you would just need to do:
# replace the lines for delete with:
<%= link_to "Destroy", project_path(@album),
*:*confirm => 'Are you sure?', :method => :delete %>
# replace the line
<%= link_to('Edit', :action => 'edit', :id => @album.id ) %>
# with:
<%= link_to "Edit", edit_album_path(@album) %>
But if you are inserting custom actions (like 'alt_album_list') you may want
to postpone moving to Rest for the moment. I just showed the above to let
you know.

Yes, David Black book is great for Ruby; the AWDWR is great for Rails.
One note: my updated advice for a person seriously interested in Ruby would
be:
a) first, David Black's book mentioned above, as introduction to Ruby
b) then, "The Ruby Programming Language", by David Flanagan (with
contributions from Matz). Not only it shows 1.8, but also 1.9 (in a very
natural way, without confusion). An extraordinary book.
