带有 Rspec2 和 authlogic 的 Rails 3：无法指定请求和视图

Question

我在为我的视图和请求创建规范时遇到问题。 我的一些控制器使用 named_scope，如下所示：

 #projects_controller.rb
 @projects = Project.with_user( current_user)

 ## project.rb:
 scope :with_user, lambda {|u|  {:joins => :client, :conditions => {:clients => {:user_id => u.id} } }}

但以下规范给出了错误：

规格：

describe "GET /projects" do
    it "works! (now write some real specs)" do
      get projects_path
    end 

错误：

6) Projects GET /projects works! (now write some real specs)
     Failure/Error: get projects_path
     Called id for nil, which would mistakenly be 4 -- if you really wanted the id of nil, use object_id
     # ./app/models/project.rb:9:in `block in <class:Project>'
     # /home/mping/.rvm/gems/ruby-1.9.2-rc2/gems/activerecord-3.0.0.rc/lib/active_record/named_scope.rb:95:in `call'
     # /home/mping/.rvm/gems/ruby-1.9.2-rc2/gems/activerecord-3.0.0.rc/lib/active_record/named_scope.rb:95:in `block in scope'
         # ./app/controllers/projects_controller.rb:4:in `index'

我的视图规范中有类似的错误：

 4) projects/show.haml renders attributes in <p>
     Failure/Error: render
     undefined method `name' for nil:NilClass
     # /home/mping/.rvm/gems/ruby-1.9.2-rc2/gems/activesupport-3.0.0.rc/lib/active_support/whiny_nil.rb:48:in `method_missing'
     # ./app/views/projects/show.haml:4:in `_app_views_projects_show_haml___1706343108022772066_34134280__4548622860215298334'

在我看来，我需要对 authlogic 定义的 current_user 方法进行存根，以便能够前进。我如何指定视图和请求？谢谢

Answer 1

我刚刚在这里成功使用了解决方案：http://spacevatican.org/2011/12/5/request-specs-and-authlogic

before(:each) do
  activate_authlogic
  @user = FactoryGirl.create(:user)
  UserSession.create @user
  cookies['user_credentials'] = "#{@user.persistence_token}::#@user.send(@user.class.primary_key)}"
end

Answer 2

存根current_user 可能是一种令人沮丧的经历。您可以按照 Authlogic 文档中的建议，通过创建用户并登录来在规范中获得必要的会话功能。例如。

include Authlogic::TestCase
activate_authlogic
@user = Factory.create(:user)
UserSession.create(:user)

退出：

session = UserSession.find
session.destroy if session
