I''m working on the onlamp tutorial, and I''m to the point where
I have
the following controller:
class RecipeController < ApplicationController
scaffold :recipe
end
I can enter a new recipe, list recipes, show recipes, but if I click
edit from the list view, I get the error "Couldn''t find Recipe
without
an ID". Same response for edit and destroy. However, the ID is shown
in the table.
Since I''ve only entered a single line of code (scaffold :recipe), and
the other pages seem to work, I''m uncertain what the deal is or how to
fix this. Google has nothing. Any pointers?
Platform:
WEBrick 1.3.1
ruby 1.8.2 (2004-12-25) [i386-mswin32]
actionmailer (0.6.1)
actionpack (1.4.0)
activerecord (1.6.0)
rails (0.9.5)
rake (0.4.15)
Found the problem. My id field was uppercase. The embarassing thing is that the tutorial specifically states that it needs to be lower case, and I missed it because I was in a rush. Oops...

I even more glad that I didn''t get a chance to respond until now! :-) Just proves the old adage that if you procrastinate long enough the task might just go away. Curt
hi curt- just going through the tutorial i found that the rake tests fail UNLESS i do ruby scripts/new_model Todos ruby scripts/new_controller todos that is, of course, using the plural table def. provided in the tutorial. the docs suggest that this plural/singlular mapping should be accounted for : is this correct? iff not is this bug known?

As far as I know, the RPA guys stopped packaging Rails. They should drop it from the repository rather than abandon releases with an old version. I assume there''s some issue with gems; here''s a tarball: http://rubyforge.org/frs/download.php/2767/rails-0.9.5.tgz jeremy
