RSpec：ActionView :: Template :: Error：nil的未定义方法`full_name’：NilClass

启动规范测试时，我收到此错误。 我知道没有设置与用户的连接。 我该怎么办才能通过考试？

RSpec文件：posts_controller_spec.rb

require 'spec_helper' include Devise::TestHelpers describe PostsController do render_views context "Logged in as user" do let(:user) { FactoryGirl.create(:user) } before { login_as(user) } context "on viewing index page" do let!(:p) { FactoryGirl.create(:post) } before { get :index } it { should respond_with(:success) } it { assigns(:posts).should == [p] } end end end 

我的观点：_home.html.erb

RSpec失败：

 PostsController Logged in as user on viewing index page Failure/Error: before { get :index } ActionView::Template::Error: undefined method `full_name' for nil:NilClass # ./app/views/posts/_home.html.erb:5:in `block in _app_views_posts__home_html_erb__709569216_93469850' # ./app/views/posts/_home.html.erb:2:in `each' # ./app/views/posts/_home.html.erb:2:in `_app_views_posts__home_html_erb__709569216_93469850' # ./app/views/posts/index.html.erb:1:in `_app_views_posts_index_html_erb___825727830_90641210' # ./spec/controllers/posts_controller_spec.rb:33:in `block (4 levels) in ' 

Answer 1

如果没有看到Post和User模型，看起来你需要改变

 let!(:p) { FactoryGirl.create(:post) } 

至

 let!(:p) { FactoryGirl.create(:post, :user => user) } 

要么

 let!(:p) { FactoryGirl.create(:post, :user_id => user.id) } 

正确设置关联。

但是，如果您的视图假设Post 总是有User ，也许您的Post模型应该validationUser的存在，或者您应该更改视图以处理Post没有User 。
