我一直在阅读 M.Hart 的 Rails 教程。在其中一个部分中，您为每个不属于您自己的用户在用户索引页面上实现删除链接；假设您是管理员用户。我还想在每个用户的个人资料页面中实现一个删除链接。我将删除链接代码放入部分中，它在索引页面和单个用户显示页面上运行良好，但在将部分添加到显示页面代码后，我仍然遇到 RSpec 失败。我的代码在下面......顺便说一句 - 主用户与管理员用户相同。
用户/show.html.erb
<section>
<%= gravatar_for @user %>
<h3><%= @user.name %></h3>
<div id="profile_delete_link"><%= render 'shared/user_delete_link', user: @user %></div>
</section>
共享/user_delete_link（部分 -> _user/delete/link.html.erb）
<% if !current_user?(user) && current_user.master? %>
>> <%= link_to "delete", user, method: :delete, data: { confirm: "You sure?" } %>
<% end %>
user_pages_spec.rb -> 下面的代码是如果将部分（以上）添加到用户/显示代码中的规范。当部分被删除时，这些规格会变回绿色
describe "profile page" do
let(:user) { FactoryGirl.create(:user, name: "foo bar") }
let!(:mp1) { FactoryGirl.create(:micropost, user: user, content: "Foo") }
let!(:mp2) { FactoryGirl.create(:micropost, user: user, content: "Bar") }
before { visit user_path(user) }
it { should have_selector('h3', text: user.name) }
it { should have_selector('title', content: "F.Bar") }
describe "microposts" do
it { should have_content(mp1.content) }
it { should have_content(mp2.content) }
it { should have_content(user.microposts.count) }
end

用户.rb

email_regex = /^[_+a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,4})$/i
attr_accessible :name, :email, :password, :password_confirmation
has_many :microposts, dependent: :destroy

validates :password, :presence => true, :length => { within: 5..50 }
validates :password_confirmation, :presence => true
def feed
Micropost.where("user_id = ?", id)
end
end
user_controller.rb 显示和索引操作以及过滤器之前
before_filter :authorize, only: [:index, :edit, :update, :destroy]
before_filter :correct_user, only: [:edit, :update]
before_filter :master_user, only: [:destroy]
def index
@users = User.all
end
def show
@user = User.find(params[:id])
@microposts = @user.microposts.paginate(page: params[:page])
@title = initials_of @user.name
end
如果您希望我发布任何代码或添加更多信息，请让我知道:) 提前谢谢。
更新：RSpec 错误：
UserPages profile page microposts
Failure/Error: before { visit user_path(user) }
ActionView::Template::Error:
