如果我的Post模型中有范围,我将看不到我的帖子列表:

模型:

class Post
  include Mongoid::Document
  include Mongoid::Timestamps
  ...
  scope :last_nine, where(:published.ne => nil).limit(9).order_by([:created_at, :desc])
end

控制器:

def index
 @posts = Post.last_nine.where(locale: locale)
  respond_to do |format|
    format.html
  end
end

与水豚的集成测试:

require 'spec_helper'
describe "Posts" do
  let!(:posts) { FactoryGirl.create_list(:post, 3) }
  subject { page }
  describe "index page should have last nine results" do
    posts.each do |p|
      current_path.should == root_path
      should have_selector "h4 a", :text => post.title
    end
    save_and_open_page
  end
end

我用方法看不到我在 capybara 输出中的最后九个帖子save_and_open_page

但是,如果我删除@posts = Post.last_nine.where(locale: locale)并添加@posts = Post.all到我的控制器中:

def index
   @posts = Post.all
    respond_to do |format|
      format.html
    end
  end

我的测试运行良好,@posts = Post.all我可以在 capybara 输出中看到我的帖子列表。

如何使用模型范围测试我与 capybara 的集成测试?
