I have checked out your code and everything is both the exact same. What I am thinking is that it is something in the database maybe. I am getting two errors, one from each page, edit.rhtml and list.rhtml. From the edit page, I get this:

I have had a very similar problem which I solved on Win2k with Peter's solution below. The curious thing is, when I run the original syntax on WinXP it works. I was using this tutorial as a template/learning experience to write a small message board program. Until I lean more, I have had to create win2k and xp versions!

I am also getting a similar error:
RuntimeError in Recipe#edit
Showing /recipe/edit.rhtml where line #20 raised:
Called id for nil, which would mistakenly be 4 -- if you really wanted the id of nil, use object_id
Extracted source (around line #20):
17:
18: <select name="recipe[category_id]">
19: <% @categories.each do |category| %>
20: <option value="<%= category.id %>" <%= ' selected' if category.id == @recipe.category.id %>><%= category.name %></option>
21: <% end %>
22: </select>
23:
Does anyone know what this is or how I can fix it? I thought I had triple-checked my code. -

Fixed the problem.
Basically I had to change this:
<%= ' selected' if category.id == @recipe.category.id %>
to this:
<%= ' selected' if category.id == @recipe.category_id %>

Check your database and make sure all of your recipe entries have valid category ids.

This looks like the same problem that Peter just resolved above in the post "Couldn't find Recipe without an ID". Please try his solution. -

To get past the list.rhtml page, I omitted the line 18 that states
<td><%= recipe.category.name %></td>
Now it enables me to see the page, but still is not doing me any good since it did not solve the problem. With that, on the edit.rhtml I changed line 24 to:
<%= 'selected' if category.id == @recipe.category_id %>>
Instead of:
<%= 'selected' if category.id == @recipe.category.id %>>
Does that make sense with that second change? Thanks! -

@recipe.category_id points to the foreign_key in the table recipe called category_id,so it makes perfect sense. @recipe.category.id points to a column that doesn`t exist in the table recipe. -

I tried it and still getting the same issue and same errors. I am sorry to be posting this, but still learning and not familiar enough to get this one going. -

Make sure that every recipe in your database has an assigned category.
Also, near the beginning og part 2 of this article, there is a link to the source code for a working version of part 1 (hopefully it still works since Rails 0.13 was just released). Anyway, you can download my sourcecode and see if that works, and then compare it with what youhave. -

the column id must be in lowercase - id - not Id, as mysql defines it first, in the database - just change the column name; rails use a lot of concepts about naming
