我即将结束Hartl rails教程并遇到了一个我似乎无法弄清楚的Rspec问题。 http://www.railstutorial.org/book/user_microposts#sec-access_control清单10.23中引入的2个测试失败，并显示以下消息：
Failures:
1) Authentication authorization for non-signed-in users in the Microposts controller submitting to the create action
Failure/Error: before { post microposts_path }
ActionController::ParameterMissing:
param is missing or the value is empty: micropost

# ./app/controllers/microposts_controller.rb:5:in `create'
# ./spec/requests/authentication_pages_spec.rb:107:in `block (6 levels) in <top (required)>'
2) Authentication authorization for non-signed-in users in the Microposts controller submitting to the destroy action
Failure/Error: before { delete micropost_path(FactoryGirl.create(:micropost)) }
ActionView::MissingTemplate:
Missing template microposts/destroy, application/destroy with {:locale=>[:en], :formats=>[:html], :handlers=>[:erb, :builder, :raw, :ruby, :jbuilder, :coffee]}. Searched in:

这是我的authentication_pages_spec.rb：

对于数字1）似乎它正在寻找一个微博但它应该完全通过并且只需转到登录页面（如下所示，微博控制器具有之前的操作设置以检查用户是否已签名如果他们不将它们转发到登录页面......这适用于所有行动）。
对于数字2）它正在寻找一个不会而且永远不会存在的视图？它为什么这样做？如何阻止此行为。
似乎应用程序绕过了微博控制器中的前置过滤器？
这是我的microposts_controller.rb：
class MicropostsController < ApplicationController
before_action :signed_in_user
def create
@micropost = current_user.microposts.build(micropost_params)
if @micropost.save
flash[:success] = "Micropost created!"
redirect_to root_url
else
render 'static_pages/home'
end
end
def destroy
end
private
def micropost_params
params.require(:micropost).permit(:content)
end
end
＆安培;我的signed_in_user和sign_in？位于我的sessions_helper.rb
中的方法def signed_in_user
unless signed_in?
store_location
redirect_to signin_url, notice: "Please sign in."
end
end
def signed_in?
!current_user.nil?
end
有关我的测试失败原因的任何见解？
答案 0 :(得分：0)
问题解决了。不知道我是怎么错过的，但我在运行测试时仍然登录了。在运行未签名的用户帖子和销毁测试的Microposts之前注销是所有需要的。我在authenication_pages_spec.rb中添加了注销代码，如下所示：
describe "in the Microposts controller" do
before do
click_link "Sign out"
describe "submitting to the create action" do
before { post microposts_path }
specify { expect(response).to redirect_to(signin_path) }
end
describe "submitting to the destroy action" do
before { delete micropost_path(FactoryGirl.create(:micropost)) }
specify { expect(response).to redirect_to(signin_path) }
end
end
end
