Subject: rails -> add a column -> NoMethodError in Admin#edit

[While I try to get on the Rails mailing list here...]

Rubies:

I am a Ruby on Rails newbie, and have been reading the book, "Agile Web 
Development with Rails", by Thomas & Hansson.

I seem to be stuck on page 61. The shtick is we create a database table, 
then go back and add a column. The column appears fine in my SQLite3 
database, and I used its test fixture to populate the column.

Then to rebuild the table's admin interface, I invoke "ruby script/generate 
scaffold Product Admin"... But the new column does not show up on the 
/admin/show/1 page, and /admin/edit/1 complains like this:

----8<---------------------------------

 NoMethodError in Admin#edit

Showing app/views/admin/_form.rhtml where line #17 raised:

undefined method `strength' for #<Champ:0xb742ca68>

Extracted source (around line #17):

14: <%= text_field 'champ', 'account'  %></p>
15:
16: <p><label for="champ_strength">Strength</label><br/>
17: <%= text_field 'champ', 'strength'  %></p>
18: <!--[eoform:champ]-->
19:

Trace of template inclusion: /app/views/admin/edit.rhtml

----8<---------------------------------

Now because I naturally don't understand the entire stack yet, I don't know 
how to work-around this, or how to fix it directly. Any help?
