任何对Rails 4有更多经验的人都能帮助我吗？我目前正在阅读“Rails 4 in Action”，我无法从书中获得其中一个规范（具体来自第7.5章：基本访问控制 - 基于命名空间的CRUD）。 我有一个规范，创建一个具有管理员权限的FactoryGirl用户，并尝试创建一个具有管理员权限的新用户。
spec/features/admin/creating_users_spec.rb
require 'spec_helper'
feature "Creating Users" do
let!(:admin) { FactoryGirl.create(:admin_user) }
before do
sign_in_as!(admin)
visit '/'
click_link "Admin"
click_link "Users"
click_link "New User"
end
scenario 'Creating a new user' do
fill_in "Email", with: "newbie@example.com"
fill_in "Password", with: "hunter2"
click_button "Create User"
expect(page).to have_content("User has been created.")
end
end
当我运行此规范时，我相信我一直收到“密码确认不能为空白错误”。

以下是创建它的工厂：
FactoryGirl.define do
sequence(:email) {|n| "user#{n}example.com" }
factory :user do
name "username"
email { generate(:email) }
#email "newbie@example.com"
password "hunter2"
password_confirmation "hunter2"
factory :admin_user do
admin true
end
end
end
这是管理员控制器：
class Admin::UsersController < Admin::BaseController
def new
@user = User.new
end
def index
@users = User.order(:email)
end
def create
@user = User.new(user_params)
if @user.save
flash[:notice] = "User has been created."
redirect_to admin_users_path
else
flash.now[:alert] = "User has not been created."
render action: "new"
end
end
private
def user_params
params.require(:user).permit(:name, :password, :password_confirmation)
end
end
这是用户模型：
class User < ActiveRecord::Base
attr_accessible :name, :password, :password_confirmation
has_secure_password
end
最后这里是管理视图表单，其中填写了所有这些信息：
<%= form_for [:admin, @user] do |f| %>
<% if @user.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(@user.errors.count, "error") %> prohibited
this user from being saved:</h2>
<ul>
<% @user.errors.full_messages.each do |msg| %>
<li><%= msg %></li>
<% end %>
</ul>
</div>
<% end %>
<p>
<%= f.label :email %>
<%= f.text_field :email %>
</p>
<p>
<%= f.label :password %>
<%= f.password_field :password %>
</p>
<p>
<%= f.check_box :admin %>
<%= f.label :admin, "Is an admin?" %>
</p>
<%= f.submit %>
<% end %>
我不知道如何解决这个问题。我已尝试在表单中创建另一个字段以进行密码确认，然后在规范中包含fill_in，但这没有做任何事情。我觉得它与具有某种限制的模型有关，除非有密码确认，否则不允许创建用户。但我不太确定。如果有人可以提供帮助，我真的很感激。

我尝试在表单中创建另一个字段以进行密码确认，然后在规范中包含了fill_in，但没有做任何事情。
将其放回，然后删除用户模型中的整个attr_accessible行。
Rails 4中默认允许使用大量分配的属性作为其strong parameters策略的一部分 - 您不必在模型中明确地将属性列入白名单。
如果这不起作用，请发布包含新password_confirmation表单字段和规范的更新视图。

那很有用！

这是规范：
require 'spec_helper'
feature "Creating Users" do
let!(:admin) { FactoryGirl.create(:admin_user) }
before do
sign_in_as!(admin)
visit '/'
click_link "Admin"
click_link "Users"
click_link "New User"
end
#=begin
scenario 'Creating a new user' do
fill_in "Email", with: "newbie@example.com"
fill_in "user[password]", with: "hunter2"
fill_in "Password confirmation", with: "hunter2"
click_button "Create User"
expect(page).to have_content("User has been created.")
end
#=end

scenario "Creating an admin user" do
fill_in "Email", with: "admin@example.com"
fill_in "Password", with: "password"

click_button "Create User"
expect(page).to have_content("User has not been created")
within("#users") do
expect(page).to have_content("admin@example.com (Admin)")
end
end

end
以下是观点：
<%= form_for [:admin, @user] do |f| %>
<% if @user.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(@user.errors.count, "error") %> prohibited
this user from being saved:</h2>
<ul>
<% @user.errors.full_messages.each do |msg| %>
<li><%= msg %></li>
<% end %>
</ul>
</div>
<% end %>
<p>
<%= f.label :email %>
<%= f.text_field :email %>
</p>
<p>
<%= f.label :password %>
<%= f.password_field :password %>
</p>
<p>
<%= f.label :password_confirmation %>
<%= f.password_field :password_confirmation %>
</p>
<p>
<%= f.check_box :admin %>
<%= f.label :admin, "Is an admin?" %>
</p>
<%= f.submit %>
<% end %>
虽然当我在用户模型中注释掉attr_accessible时，我收到了一个错误：
class User < ActiveRecord::Base
#attr_accessible :name, :password, :password_confirmation
has_secure_password
end
现在是规范：
bin/rspec spec/features/admin/creating_users_spec.rb

所以也许当我最后一次尝试创建密码确认字段时，我可能会遗漏一些东西，这次我没有 - 所以它有效。
非常感谢！
