Something wrong in my sequence of factory creation

I was hoping someone would spot why this wouldn't work.

I am getting an error thats being called because the attributes I specify with开发者_开发问答 Factory_Girl are not being applied to the stub before validation.

The Error:

undefined method `downcase' for #<Category:0x1056f2f60>

RSpec2

it "should vote up" do
  @mock_vote = Factory.create(:vote)
  Vote.stub(:get_vote).and_return(@mock_vote)
  get :vote_up, :id => "1"        
end

Factories

Factory.define :vote, :class => Vote do |v|
  v.user_id "1"
  v.association :post
end

Factory.define :post, :class => Post do |p|
  p.category "spirituality"
  p.name "sleezy snail potluck"
  p.association :category
end

Factory.define :category, :class => Category do |c|
  c.name "spirituality"
  c.id "37"
end

Post.rb - Model

before_save           :prepare_posts
validate              :category?

def prepare_posts
  self.update_attribute("category", self.category.downcase)
  if self.url?
    self.url = "http://" + self.url unless self.url.match /^(https?|ftp):\/\//
  end
end

def category?
  unless Category.exists?(:name => self.category.downcase)
    errors.add(:category, "There's no categories with that name.")
  end
  return true
end

Also, feel free to nitpick any blatantly gross looking code. :D

Thanks!!

You have a category attribute, which appears to be a string, but you also seem to have a category association which automatically creates, among other things, an attribute on Post called category, probably overwriting your category attribute. Hence, the Category class has no downcase method, because it's not a String.

Rename your category attribute to something like category_name, but really you shouldn't have that attribute at all.

Maybe where you're calling self.category.downcase you meant self.category.name.downcase?
