Rails4 - 如何验证性别[布尔型]字段我的webapp

Question

我新的轨道，并试图性别添加到我用迈克尔·哈特尔的教程

我决定使用布尔类型性别创建了现有的应用程序。 我添加了新列在迁移文件

DB /迁移/ [时间戳] _add_admin_to_users.rb

class AddAdminToUsers < ActiveRecord::Migration 
    def change 
    add_column :users, :admin, :boolean, default: false 

    #Start - Adding for gender and dob 
    add_column :users, :date_of_birth, :datetime 
    add_column :users, :is_female, :boolean, default: false 
    #End - Adding for gender and dob 

    end 
end 

运行以下与我的新列创建表

$bundle exec rake db:migrate 

决定创建选择框，因为我无法在重复尝试后创建单选按钮

应用程序/模型/ user.rb

class User < ActiveRecord::Base 
. 
. 
GENDER_TYPES = [ ["Male","0"], [ "Female","1" ] ] 
validates :is_female, presence: true, inclusion: { in: ["0","1"] } 
. 
. 

更新测试 测试/模型/ user_test.rb

require 'test_helper' 

class UserTest < ActiveSupport::TestCase 

    def setup 
    @user = User.new(name: "Example User", email: "user@example.com", 
        password: "foobar", password_confirmation: "foobar", 
        date_of_birth: "08/04/1987", is_female: "0") 
    end 
. 
. 

这是我的观点注册表格

的选择框片段

app/views/users/new.html.erb

<%= f.label :is_female, "Gender" %> 
<%= f.select :is_female, User::GENDER_TYPES, class: 'form-control' %> 

这是从HTML注册表格

   <div> 
       <label for="user_is_female">Gender</label> 
       <select id="user_is_female" name="user[is_female]"><option value="0">Male</option> 
<option value="1">Female</option></select> 
       </div> 

添加以下是从质量分配漏洞免疫选择框片断

应用程序/控制器/ users_controller.rb

class UsersController < ApplicationController 
. 
. 
    private 

    def user_params 
     params.require(:user).permit(:name, :email, :password, 
            :password_confirmation, :is_female, :date_of_birth) 
    end 
. 
.

无法保存男性用户

能给... AVE女性用户

>> 

is_female： “1”，is_female： “真”工作
我不知道为什么
is_female： “0”和is_female： “假”不起作用？

请帮忙。

Answer 1

我发现了它。 存在：在

validates :is_female, presence: true, inclusion: { in: [true,false] } 

是造成这个问题。 实测值中下面的 “钢轨4路由O.费尔南德斯，K.福斯蒂诺& V.库什纳”

validates_inclusion_of :is_female, in: [true, false] 

这是工作。 Yippie和所有的测试都通过了。

Answer 2

由于性别是一个布尔字段，你应该使用

validates :is_female, presence: true, inclusion: { in: [true,false] }
