在我创建工厂的过程中出了点问题

我希望有人能发现为什么这行不通。

我得到一个调用的错误,因为我用Factory\u Girl指定的属性在验证之前没有应用到存根。

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

RSpec2型

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

工厂

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

后rb-型号

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

另外,请随意挑剔任何明显粗俗的代码。:D个

谢谢!!
