Why, when I am trying to manually assign permalinks, would I get this  
from the ruby console:

s.update\_attribute :permalink, ‘my-shiny-weblog’  
NoMethodError: undefined method `permalink=' for #<Story:0x32361c8> from /usr/local/lib/ruby/gems/1.8/gems/activerecord-1.15.2/lib/ active_record/base.rb:1858:in`method\_missing’  
from /usr/local/lib/ruby/gems/1.8/gems/activerecord-1.15.2/lib/  
active\_record/validations.rb:772:in `send' from /usr/local/lib/ruby/gems/1.8/gems/activerecord-1.15.2/lib/ active_record/validations.rb:772:in`update\_attribute’  
from (irb):54

If you don’t have a permalink field in your db, yes.

Pat

p.s. Actually you get that any time you don’t have a permalink= method  
(just like it says). Rails just happens to create that method for you  
based on your attributes
