So I'm a newbie to Rails and attempting to add multiple models to a
form.
I found the Railscast for "Complex Forms, Part 1" at
http://railscasts.com/episodes/73-complex-forms-part-1 which is from
2007 and at the point where the moderator, Ryan, says "Let's take a
look at our code..." and refreshes the UI and in the Railscast we see
3 Tasks below the Project. However, when I refresh my project screen,
my code shows a "NoMethodError" in the Controller with an undefined
method for the prepsteps that were added. I'm not following the
Project/Task models, but am building a Recipe/Preparation Steps models
to learn Rails. Not sure what's up except my controller needs a method
somewhere. I'm using Rails 2.3.4. Any sugggestions?
Thanks in advance!!

Error message:
NoMethodError in RecipesController#new
undefined method `prepsteps'
Following is my code:
recipes_controller.rb
def new
@recipe = Recipe.new
3.times { @recipe.prepsteps.build }
respond_to do |format|
format.html # new.html.erb
format.xml { render :xml => @recipe }
end
end
recipes\new.html.erb
<% for prepstep in @recipe.prepsteps %>
<% fields_for "recipe[prepstep_attributes][]", prepstep do |
prepstep_form| %>
<p>
<%= prepstep_form.text_field :step_number %>
<%= prepstep_form.text_field :step %>
</p>
<% end %>
<% end %>
recipe.rb
class Recipe < ActiveRecord::Base
validates_presence_of :name
has_many :prep_steps, :dependent => :destroy
accepts_nested_attributes_for :prep_steps
end
prep_steps.rb
class PrepSteps < ActiveRecord::Base
has_one :recipe, :dependent => :destroy
validates_presence_of :recipe
end
