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或完全忽略它),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"
