我查看堆栈溢出的答案,发现一些人发布了类似的问题,但解决方案没有帮助。据我所知,我的代码是完全正确的。
require 'spec_helper'
describe User do
before { @user = User.new(name: "Example User", email: "user@example.com") }
subject { @user }
it { should respond_to(:name) }
it { should respond_to(:email) }
it { should be_valid }
describe "when name is not present" do
before { @user.name = " " }
it { should_not be_valid }
end
describe "when email is not present" do
before { @user.email = " " }
it { should_not be_valid }
end
describe "when name is too long" do
before { @user.name = "a" * 51 }
it { should_not be_valid }
end
describe "when email format is invalid" do
it "should be invalid" do
addresses = %w[user@foo,com user_at_foo.org example.user@foo. foo@bar_baz.com foo@bar+baz.com]
addresses.each do | invalid_address |
@user.email = invalid_address
expect(@user).not_to be_valid
end
end
end
describe "when email format is valid" do
it "should be valid" do
addresses = %w[user@foo.COM A_US-ER@f.b.org frst.lst@foo.jp a+b@baz.cn]
addresses.each do | valid_address |
@user.email = valid_address
expect(@user).to be_valid
end
end
end
describe "when email address is already taken" do
before do
user_with_same_email = @user.dup
user_with_same_email.email = @user.email.upcase
user_with_same_email.save
end
#it "should not be valid" do
# expect(@user).not_to be_valid
#end
it { should_not be_valid }
end
end
最后一条规格失败。
我的用户验证是这样的:
class User < ActiveRecord::Base
before_save { self.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_sensative: false }
end
我完美地遵循了教程,但我似乎无法使此验证正常工作。我知道这个教程有点旧,我可能会使用一些新的宝石。我也知道这不是进行此类验证的最佳方法,但教程只是让它一开始变得非常简单。这是怎么回事?
谢谢!
修改 没有错误。当验证成功时,验证会失败。

再次编辑。 user_spec.rb已完全粘贴在任务中。对不起,我对ruby很陌生,并没有意识到可能需要帮助排除故障。

如果您继续阅读本教程,您会发现作者说测试仍未完成传递。那是因为当前的验证仍然区分大小写。
添加uniqueness: { case_sensitive: false }
会使测试按预期传递
validates :email, presence: true, format: { with: VALID_EMAIL_REGEX },
uniqueness: { case_sensitive: false }

我认为它刚刚解决了。也许有人可以解释刚刚发生的事情。我决定继续学习本教程并将gem 'bcrypt-ruby', '3.1.2'
添加到gemfile中。然后我跑了bundle install
。
然后我尝试运行rspec spec/
并返回错误:
Migrations are pending; run 'bin/rake db:migrate RAILS_ENV=development' to resolve this issue.
但当我跑rake db:migrate
时,什么也没发生。所以我用Google搜索并找到了this SO post a solution。
我跑了:
rake test:prepare
rake db:migrate
然后所有测试都通过了。
也许我的测试环境对我疯狂了?我仍然不知道刚刚发生了什么。

您可以在user_with_same_email.valid?
之前添加.save
并提供其输出,但我相信它会true
,因为:
您尚未更改id
的{{1}}
您只需更改email的大小写,但它也同样有效,因此“A@A.COM”和“a@a.com”相同且有效。< / p>
@user
返回#valid
,因为true
存在,有良好的:email
,并且仍然是唯一的。
