我是rails的新手，并尝试将Gender添加到我使用Michael Hartl教程创建的现有应用程序
我决定对Gender使用boolean类型。 我在迁移文件中添加了新列
db / migrate / [timestamp] _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
使用我的新列
创建表格$bundle exec rake db:migrate
决定创建选择框，因为我在重复尝试后无法创建单选按钮
应用/模型/ user.rb
class User < ActiveRecord::Base
.
.
GENDER_TYPES = [ ["Male","0"], [ "Female","1" ] ]
validates :is_female, presence: true, inclusion: { in: ["0","1"] }
.
.
更新了测试 的测试/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
.
.
这是我的注册表单
视图中的选择框摘录app / views / users / new.html.erb
<%= f.label :is_female, "Gender" %>
<%= f.select :is_female, User::GENDER_TYPES, class: 'form-control' %>
这是来自HTML注册表格的选择框摘录
<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>
添加以下内容以免受群发分配漏洞影响
应用/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
.
.

is_female：“1”， is_female：“true”正在运作
我不知道为什么
is_female：“0”和is_female：“false”不起作用？
请帮助。
答案 0 :(得分：1)
由于性别是一个布尔字段，您应该使用
validates :is_female, presence: true, inclusion: { in: [true,false] }
答案 1 :(得分：0)
我找到了。 存在：在
中为真validates :is_female, presence: true, inclusion: { in: [true,false] }
造成了这个问题。 在O. Fernandez，K。Faustino＆amp; Sons的＆＃34; The Rails 4 Way中找到以下内容。 V. Kushner＆＃34;
validates_inclusion_of :is_female, in: [true, false]
这很有效。 Yippie和所有测试都在通过。
