为什么水豚/ rspec会失去current_user？

Question

以下规范失败并重新执行。我已经尝试了一切，但无法让它工作。如果我手动测试它看起来很好:(一些帮助/提示将非常好！

如果他/她拥有正确的令牌（在URL中），加入操作应该将已登录的用户添加到公会/ ）如果用户没有登录，动作将重定向到登录页面，并将令牌和ID保存到cookie。登录后，如果cookie被设置，用户将被重定向到加入页面

I'我发现在测试过程中current_user会丢失，会话变量仍然存在，我有一个标准的Authlogic设置，所有其他测试都通过了，所以我真的不知道发生了什么问题，我是RSpec /水豚，但黄瓜/水豚测试（我从中迁徙）也失败了，所以我认为这是水豚问题。

失败规格：

describe GuildsController do 
    fixtures :roles 

    def login 
    @user = Factory(:User) 
    visit login_path 
    fill_in 'Login', :with => @user.login 
    fill_in 'Password', :with => 'password' 
    click 'Login' 
    page.should have_css(".notice") 
    end 

    def assing_user_to_guild_as(role) 
    role_id = Role.where(:name => role).first.id 
    @guild.assignments << Assignment.new(:role_id => role_id, :user_id => @user.id, :guild_id => @guild.id) 
    end 

    before(:each) do 
    @guild = Guild.first || Factory(:Guild).build 
    visit root_path 
    end 

    context "a user" do 
    before(:each) do 
     login 
    end 

    it "should be able to join a guild with a valid token" do 
     visit "guilds/#{@guild.id}/join/#{@guild.token}" 
     @guild.members.include?(@user.login).should be_true 
     page.should have_css(".notice") 
    end 

    it "shouldn't be able to join a guild with a invalid token" do 
     visit "guilds/#{@guild.id}/join/#{@guild.token+"invalid"}" 
     @guild.members.include?(@user.login).should be_false 
     page.should have_css(".error") 
    end 
    end 
end 

控制器动作：

def join 
    @guild = Guild.find(params[:id]) 
    respond_to do |format| 
     if current_user.nil? 
     flash[:error] = t("have_to_be_logged_in") 
     unless params[:token].nil? 
      cookies[:rguilds_jg_token] = params[:token] 
      cookies[:rguilds_jg_gid] = params[:id] 
     end 
     format.html { redirect_to(login_path) } 
     else 
     unless cookies[:rguilds_jg_token].nil? && cookies[:rguilds_jg_gid].nil? 
      cookies.delete(:rguilds_jg_token) 
      cookies.delete(:rguilds_jg_gid) 
     end 
     if @guild.verified? 
      if params[:token] == @guild.token 
      unless @guild.users.include?(current_user) 
       @guild.assignments << Assignment.create(:user_id => current_user.id, :role_id => Role.find_by_name("member").id) 
       flash[:notice] = t('guilds.joined') 
       format.html { redirect_to(@guild) } 
      else 
       flash[:error] = t('guilds.already_joined') 
       format.html { redirect_to(@guild) } 
      end 
      else 
      flash[:error] = t('guilds.invalid_token') 
      format.html { redirect_to(@guild) } 
      end 
     else 
      flash[:error] = t('guilds.not_verified') 
      format.html { redirect_to(@guild) } 
     end 
     end 
    end 
    end

# In your test_helper.rb/spec_helper.rb 

class ActiveRecord::Base 
    mattr_accessor :shared_connection 
    @@shared_connection = nil 

    def self.connection 
    @@shared_connection || retrieve_connection 
    end 
end 

# Forces all threads to share the same connection. This works on 
# Capybara because it starts the web server in a thread. 
ActiveRecord::Base.shared_connection = ActiveRecord::Base.connection
