Rails的理解不同的正則表達式，然後rubular

Question

我想做一個簡單的基於正則表達式的電子郵件驗證：

class EmailValidator < ActiveModel::EachValidator 
    def validate_each(record, attribute, value) 
    unless value =~ /\A([\S]+)@((?:[-a-z0-9]+\.)+[a-z]{2,})\z/i 
     record.errors[attribute] << (options[:message] || 'is not an email') 
    end 
    end 
end 

這是Rails文檔中提到

。 我已經在rubular和everythings中檢查過它的工作正常，但是在rails中，由於某種原因（john.doe@example.com）帶有點在本地地址的電子郵件未通過驗證。奇怪的是它接受任何其他非空白字符（例如& ^％＃！*（），當然不包括@）。

class User < ApplicationRecord 
    validates :email,  presence: true, length: { maximum: 64 }, 
         uniqueness: { case_sensitive: false }, email: true 
    validates :password, presence: true, length: { in: 8..64 } 
    validates :first_name, length: { in: 2..16 }, allow_blank: true 
    validates :last_name, length: { in: 2..32 }, allow_blank: true 
    validates :student_id, length: { in: 5..6 }, allow_blank: true, 
         numericality: true 
end 

而失敗的測試：

test 'should validate email with special characters in local address' do 
    @user.email = 'john.doe@domain.com' 
    assert @user.valid? 
    end 

全user_test.rb

class UserTest < ActiveSupport::TestCase 
    def setup 
    @user = User.new(email: 'johndoe@domain.com', password: 'password12', 
        first_name: 'John', last_name: 'Doe', 
        student_id: '112233') 
    end 

    # Presence validation 
    test 'user validate user' do 
    assert @user.valid? 
    end 

    test 'should not validate empty email' do 
    @user.email = '' 
    assert_not @user.valid? 
    end 

    test 'should not validate blank password' do 
    @user.password = '  ' 
    assert_not @user.valid? 
    end 

    test 'should validate blank first name' do 
    @user.first_name = '' 
    assert @user.valid? 
    end 

    test 'should validate blank last name' do 
    @user.last_name = '' 
    assert @user.valid? 
    end 

    test 'should validate blank student id' do 
    @user.student_id = '' 
    assert @user.valid? 
    end 

    # Length validation 
    test 'should not validate too long email' do 
    @user.password = 'a' * 65 
    assert_not @user.valid? 
    end 

    test 'should not validate too long password' do 
    @user.password = 'a' * 65 
    assert_not @user.valid? 
    end 

    test 'should not validate too short password' do 
    @user.password = 'a' * 7 
    assert_not @user.valid? 
    end 

    test 'should not validate too long first name' do 
    @user.first_name = 'a' * 17 
    assert_not @user.valid? 
    end 

    test 'should not validate too short first name' do 
    @user.first_name = 'a' 
    assert_not @user.valid? 
    end 

    test 'should not validate too long last name' do 
    @user.last_name = 'a' * 33 
    assert_not @user.valid? 
    end 

    test 'should not validate too short last name' do 
    @user.last_name = 'a' 
    assert_not @user.valid? 
    end 

    test 'should not validate too long student id' do 
    @user.student_id = '1234567' 
    assert_not @user.valid? 
    end 

    test 'should not validate too short student id' do 
    @user.student_id = '1234' 
    assert_not @user.valid? 
    end 

    # Email format validation 
    test 'should not validate email with wrong format' do 
    @user.email = 'john.doe@domain' 
    assert_not @user.valid? 
    end 

    test 'should validate email with special characters in local address' do 
    @user.email = 'john.doe@domain.com' 
    assert @user.valid? 
    end 

    test 'should not validate email with special characters in domain' do 
    @user.email = 'john.doe@dom_ain.com' 
    assert_not @user.valid? 
    end 

    # Numeric-only validation 
    test 'should not validate student id with non-numeric characters' do 
    @user.student_id = 'ab123c' 
    assert_not @user.valid? 
    end 

    # Uniqueness validation 
    test 'should not validate duplicated email' do 
    @copycat_user = @user.dup 
    @user.save 
    assert_not @copycat_user.valid? 
    end 
end 

任何想法可能是對於怪異的行爲的原因是什麼？

Answer 1

我有決議。

我有相同的參數作爲夾具

@user = User.new(email: 'johndoe@domain.com', password: 'password12', 
       first_name: 'John', last_name: 'Doe', 
       student_id: '112233') 

由於電子郵件必須是唯一的，它給我的電子郵件已經採取了一個錯誤。
