本章介绍如何添加记忆令牌以确保记住用户登录状态,并且只有在用户明确注销时才会清除会话。我理解在我的应用中使用此功能的重要性,因此要确保它正常工作。当我运行
时,我遇到了一堆错误$ bundle exec rspec spec/
我怀疑他们与我的用户模型有关,因为他们除了一个包含:
NoMethodError:
undefined method `remember_token=' for #<User:...>
,最后一个包含
Failure/Error: it { should respond_to(:remember_token) }
然后指向我的user_spec.rb,user.rb和authentication_pages_spec.rb文件,我在这里包含了大部分(相关部分)。
user.rb:
# == Schema Information
#
# Table name: users
#
# id :integer not null, primary key
# name :string(255)
# email :string(255)
# created_at :datetime not null
# updated_at :datetime not null
#
class User < ActiveRecord::Base
attr_accessible :name, :email, :password, :password_confirmation
has_secure_password
before_save { |user| user.email = email.downcase }
before_save :create_remember_token
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, length: { minimum: 6 }
validates :password_confirmation, presence: true
private
def create_remember_token
self.remember_token = SecureRandom.urlsafe_base64
end
end
authentication_pages_spec.rb:
require 'spec_helper'
describe "Authentication" do
subject {page}
describe "signin page" do
before { visit signin_path }
it {should have_selector('h1', text: 'Sign in')}
it {should have_selector('title', text: 'Sign in')}
end
describe "signin" do
before {visit signin_path}
describe "with invalid information" do
before {click_button "Sign in"}
it {should have_selector('title', text: 'Sign in')}
it {should have_selector('div.alert.alert-error', text: 'Invalid')}
describe "after visiting another page" do
before { click_link "Home" }
it { should_not have_selector('div.alert.alert-error') }
end
end
describe "with valid information" do
let(:user) { FactoryGirl.create(:user) }
before do
fill_in "Email", with: user.email
fill_in "Password", with: user.password
click_button "Sign in"
end
it { should have_selector('title', text: user.name) }
it { should have_link('Profile', href: user_path(user)) }
it { should have_link('Sign out', href: signout_path) }
it { should_not have_link('Sign in', href: signin_path) }
end
end
end
和user_spec.rb的开头:
# == Schema Information
#
# Table name: users
#
# id :integer not null, primary key
# name :string(255)
# email :string(255)
# created_at :datetime not null
# updated_at :datetime not null
#
require 'spec_helper'
describe User do
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 be_valid }
it { should respond_to(:password_digest) }
it { should respond_to(:password) }
it { should respond_to(:password_confirmation) }
it { should respond_to(:authenticate) }
it { should respond_to(:remember_token) }
describe "remember token" do
before { @user.save }
its(:remember_token) { should_not be_blank }
end

非常感谢任何帮助!

如果您在Heroku上的生产中遇到此错误,请在运行后执行:
heroku run rake db:migrate
您需要重新启动应用:
heroku restart

您是否生成了将列添加到用户模型的迁移?
$ rails generate migration add_remember_token_to_users
此后编辑迁移文件以添加新字段remember_token
和
之后你需要做
$ bundle exec rake db:migrate
$ bundle exec rake db:test:prepare
模型上的注释不显示列。确保执行了上述命令。

我得到了类似的测试失败错误。
我所做的是用字符串类型生成remember_token
列。
rails generate migration add_remember_token_to_users remember_token:string --force
rake db:migrate RAILS_ENV=test
之后,测试通过。

我在学习Mhartl教程时遇到了同样的问题。我解决了这个问题。当你的数据库已经拥有一些用户数据时,这个问题出现了,然后&#34; remember_token&#34;迁移不起作用。你必须清理你的日期,然后做db:migrate.like this:
rake db:drop db:create rake db:migrate(小心:这会擦除你的所有数据)
希望帮助

我遇到了同样的问题,得到了未定义的方法find_by_remember_token。
以下是我要解决的问题:
heroku run rake db:migrate
然后再次推送到heroku
git push heroku
