我有一个模特
# == Schema Information
#
# Table name: posts
#
# id :integer not null, primary key
# name :string(255)
# title :string(255)
# content :text
# created_at :datetime
# updated_at :datetime
# abstract :text
# category_id :integer
# finalversion :boolean default(FALSE)
# published_date :date
#
class Post < ActiveRecord::Base
has_many :tags
belongs_to :category
validates :published_date, :presence => true
default_scope :order => 'created_at DESC'
accepts_nested_attributes_for :tags, :allow_destroy => :true,
:reject_if => proc { |attrs| attrs.all? { |k, v| v.blank? } }
def prev_post
self.class.first(:conditions => ["id < ?", id], :order => "id desc")
end
def next_post
self.class.first(:conditions => ["id > ?", id], :order => "id asc")
end
def seo_title
title.gsub(/\s+/,'_')
end
end
和工厂
FactoryGirl.define do
factory :post do
published_date Date.today
association :category, :factory => :category
title Forgery::LoremIpsum.words
name Forgery::LoremIpsum.word
content Forgery::LoremIpsum.words(100, :random => 250)
abstract Forgery::LoremIpsum.words(100, :random => 50)
finalversion true
end
end
并且在rails控制台中我没有问题
FactoryGirl.create :post
获取有效对象并能够访问* published_date *属性。但是在我的规范中
require 'spec_helper'
(1..5).map do |i|
title = "a title\t#{i}"
escape_title = "a_title_#{i}"
perma_link = "/posts/#{i}/title/#{escape_title}"
describe "A post with title '#{title}'" do
before do
@post = FactoryGirl.create :post, :id=>i, :title => title
visit '/posts'
end
it "should appear in all links with permalink #{perma_link}" do
within "section.post_#{@post.id}" do
page.should have_xpath(%Q%.//h1/a[@href="#{perma_link}"]%)
within "div.teaser" do
page.should have_xpath(%Q%.//a[@href="#{perma_link}"]%)
end
end
end
end
end
我收到了回溯错误
5) A post with title 'a title 5' should appear in all links with permalink /posts/5/title/a_title_5
Failure/Error: @post = FactoryGirl.create :post, :id=>i, :title => title

我完全被它难住了。任何想法

答案 0 :(得分：7)
你运行rake db:test:prepare了吗？在我看来，您的Post型号有published_date，但您的工厂说它不存在。不运行此rake任务将是导致此问题的主要因素。
