我见过其他有类似问题的线程，但它们似乎没有解决我的问题。我正在按照http://ruby.railstutorial.org/上的教程进行操作，以获取基本用户注册和登录或与示例不同的项目。

基本上，当我运行 rspec 时，我不断收到此错误。我已经运行了所有的迁移和测试准备。真的被这件事难住了。

1) User should reject duplicate email addresses
 Failure/Error: User.create!(@attr)
 ActiveRecord::RecordInvalid:
   Validation failed: Password digest can't be blank, Password can't be blank, Password is too short (minimum is 6 characters), Password confirmation can't be blank
 # ./spec/models/user_spec.rb:60:in `block (2 levels) in <top (required)>'

2) User should accept valid email addresses
 Failure/Error: valid_email_user.should be_valid end
   expected #<User id: nil, name: "Example User", email: "user@foo.com", created_at: nil, updated_at: nil, password_digest: nil> to be valid, but got errors: Password digest can't be blank, Password can't be blank, Password is too short (minimum is 6 characters), Password confirmation can't be blank
 # ./spec/models/user_spec.rb:48:in `block (3 levels) in <top (required)>'
 # ./spec/models/user_spec.rb:46:in `each'
 # ./spec/models/user_spec.rb:46:in `block (2 levels) in <top (required)>'

3) User should create a new instance given valid attributes
 Failure/Error: User.create!(@attr)
 ActiveRecord::RecordInvalid:
   Validation failed: Password digest can't be blank, Password can't be blank, Password is too short (minimum is 6 characters), Password confirmation can't be blank
 # ./spec/models/user_spec.rb:25:in `block (2 levels) in <top (required)>' 

4) User should reject email addresses identical up to case
 Failure/Error: User.create!(@attr.merge(:email => upcased_email))
 ActiveRecord::RecordInvalid:
   Validation failed: Password digest can't be blank, Password can't be blank, Password is too short (minimum is 6 characters), Password confirmation can't be blank
 # ./spec/models/user_spec.rb:67:in `block (2 levels) in <top (required)>'

这是我的 user_spec

require 'spec_helper'

describe User do
  before(:each) do
    @attr = { :name => "Example User", :email => "user@example.com" }
  end

  before do
    @user = User.new(name: "Example User", email: "user@example.com",
                     password: "foobar", password_confirmation: "foobar")
  end

  subject { @user }

  it { should respond_to(:name) }
  it { should respond_to(:email) }
  it { should respond_to(:password_digest) }
  it { should respond_to(:password) }
  it { should respond_to(:password_confirmation) }
  it { should respond_to(:authenticate) }

  it { should be_valid }

  it "should create a new instance given valid attributes" do
    User.create!(@attr)
  end

  it "should require a name"  do
    no_name_user = User.new(@attr.merge(:name => ""))
    no_name_user.should_not be_valid
  end

  it "should require an email address" do
    no_email_user = User.new(@attr.merge(:email => ""))
    no_email_user.should_not be_valid
  end

  it "should reject names that are too long" do
    long_name = "a" * 51
    long_name_user = User.new(@attr.merge(:name => long_name))
    long_name_user.should_not be_valid
  end

  it "should accept valid email addresses" do
    addresses = %w[user@foo.com THE_USER@foo.bar.org first.last@foo.jp]
    addresses.each do |address|
      valid_email_user = User.new(@attr.merge(:email => address))
      valid_email_user.should be_valid end
  end

  it "should reject invalid email addresses" do
    addresses = %w[user@foo,com user_at_foo.org example.user@foo.]
    addresses.each do |address|
      invalid_email_user = User.new(@attr.merge(:email => address))
      invalid_email_user.should_not be_valid end
  end

  it "should reject duplicate email addresses" do
    # Put a user with given email address into the database.
    User.create!(@attr)
    user_with_duplicate_email = User.new(@attr)
    user_with_duplicate_email.should_not be_valid
  end

  it "should reject email addresses identical up to case" do
    upcased_email = @attr[:email].upcase
    User.create!(@attr.merge(:email => upcased_email))
    user_with_duplicate_email = User.new(@attr)
    user_with_duplicate_email.should_not be_valid
  end

  describe "when password is not present" do
    before { @user.password = @user.password_confirmation = " " }
    it { should_not be_valid }
  end

  describe "when password doesn't match confirmation" do
    before { @user.password_confirmation = "mismatch" }
    it { should_not be_valid }
  end

  describe "when password confirmation is nil" do
    before { @user.password_confirmation = nil }
    it { should_not be_valid }
  end

  describe "with a password that's too short" do
    before { @user.password = @user.password_confirmation = "a" * 5 }
    it { should be_invalid }
  end

  describe "return value of authenticate method" do
    before { @user.save }
    let(:found_user) { User.find_by_email(@user.email) }

    describe "with valid password" do
      it { should == found_user.authenticate(@user.password) }
    end

    describe "with invalid password" do
      let(:user_for_invalid_password) { found_user.authenticate("invalid") }

      it { should_not == user_for_invalid_password }
      specify { user_for_invalid_password.should be_false }
    end
  end

end

这是我的用户模型

class User < ActiveRecord::Base

  attr_accessible :name, :email, :password, :password_confirmation
  has_secure_password

  before_save { |user| user.email = email.downcase }

  validates :name, presence: true, length: { maximum: 50 }
  VALID_EMAIL_REGEX = /\A[\w+\-.]+@[a-z\d\-.]+\.[a-z]+\z/i
  validates :email, presence:   true,
            format:     { with: VALID_EMAIL_REGEX },
            uniqueness: { case_sensitive: false }
  validates :password, presence: true, length: { minimum: 6 }
  validates :password_confirmation, presence: true
end

您的验证也被破坏，如果创建用户但之后不需要密码和密码确认应该需要

validates :password, presence: true, length: { minimum: 6 }
validates :password_confirmation, presence: true

如果您稍后尝试更新用户，例如更改其名称，您将遇到问题，因为它会检查密码和密码确认但用户已经有一个密码集，通常存储在由 bcrypt 加密但未存储的 password_digist 字段中连同密码和纯文本确认。

我建议仅对新记录进行验证：

validates :password, presence: true, length: { minimum: 6 } if new?
validates :password_confirmation, presence: true if new?

在所有失败的测试中，您使用@attr = { :name => "Example User", :email => "user@example.com" }创建一个新用户。但要创建新用户，您必须设置password和password_confirmation。将这些属性添加到@attr哈希中。然后应该自动设置该password_digest字段，并且应该可以保存用户。

删除这一行

attr_accessible :name, :email, :password, :password_confirmation

它现在应该可以工作了。

这可以防止方法 rails method password= 被调用。（另见secure_password.rb）
