我对此有点困惑,因为我觉得我已经避开了常见的错误(比如错误输入 attr_accessible完全忽略它),但我仍然得到一个

Can't mass-assign protected attributes: home, work

错误在这里。我猜我错过了一些东西,但我不确定是什么。

无论如何,在我的新应用程序中,用户有一个家庭和一个工作(每个都属于一个用户),我希望用户在注册时输入它们。所以,在我的模型中:

用户.rb

attr_accessible :email, :first_name, :last_name, :password, :password_confirmation, :home_attributes, :work_attributes

  has_one :home, :work

  accepts_nested_attributes_for :work, :home

  has_secure_password

主页.rb

attr_accessible :address, :latitude, :longitude, :user_id
belongs_to :user

validates :address, presence: true

工作.rb

attr_accessible :address, :latitude, :longitude, :user_id
belongs_to :user

validates :address, presence: true

在我的控制器中

users_controller.rb

def new
    @user = User.new

  respond_to do |format|
    format.html # new.html.erb
    format.json { redirect_to @user }
  end
end

并以我的形式:

意见/用户/_form.html.haml

= form_for @user do |f|
  - if @user.errors.any?
    .error_explanation
      %h2
        = pluralize(@user.errors.count, "error") 
        prohibited this post from being saved:
      %ul
        - @user.errors.full_messages.each do |msg|
          %li= msg

  = f.label :first_name
  = f.text_field :first_name

  = f.label :last_name
  = f.text_field :last_name

  = f.label :email
  = f.text_field :email

  = f.label :password
  = f.password_field :password

  = f.label :password_confirmation, "Re-Enter Password"
  = f.password_field :password_confirmation

  = f.fields_for :home do |builder|
    = builder.label :address, "Home address"
    = builder.text_field :address
  %br
  = f.fields_for :work do |builder|
    = builder.label :address, "Work address"
    = builder.text_field :address

  .btn-group
    = f.submit 'Sign Up!', class: "btn"

看起来您还没有设置实例变量来包含这些属性。

在你的控制器中,你应该有这样的东西

def new
    @user = User.new
    @user.homes.build
    @user.works.build

  respond_to do |format|
    format.html # new.html.erb
    format.json { redirect_to @user }
  end
end

如果您不构建这些属性,表单将不知道该怎么做。
