Rails - Feb 2007 - undefined method ... from `alias_method'

0 wicked var/www % ./script/console
Loading development environment.
>> r = Recipe.find :first
NameError: undefined method `recipe_type='' for class `Recipe''
        from ./script/../config/../config/../app/models/recipe.rb:
101:in `alias_method''

In recipes_controller:

alias_method :orig_recipe_type=, :recipe_typedef recipe_type=(t)
  if t.nil?
    self.orig_recipe_type = guess_recipe_type
    self.recipe_type_is_guess = true
  else
    self.orig_recipe_type = t
    self.recipe_type_is_guess = false
  end
end

recipe_type is a column in my recipes table.  Does this happen because
AR uses method_missing to do recipe_type=?  Can I get around this?

Thanks,
--Dean

Correct.  Use super.

def recipe_type=(t)
  if t.nil?
    super guess_recipe_type
    self.recipe_type_is_guess = true
  else
    super t
    self.recipe_type_is_guess = false
  end
end

Thanks for the reply Chris and the follow up explanation.  That
explains why alias_method works for my association assignments  :-)
