Question

无法确定如何设置此表单。我有两个模型Business和User。商家有belong_to :business，用户有Rails.application.routes.draw do devise_for :users, :controllers => { :registrations => 'registrations' } root 'pages#index' resources :businesses do resources :users end # For details on the DSL available within this file, see http://guides.rubyonrails.org/routing.html end。我试图创建一个初始表单来创建一个企业和第一个用户（所有者）。这是我的路线文件：

class Business < ApplicationRecord

    has_many :users
    accepts_nested_attributes_for :users
end

business.rb

class User < ApplicationRecord
  rolify
  # Include default devise modules. Others available are:
  # :confirmable, :lockable, :timeoutable and :omniauthable
  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :validatable

  belongs_to :business
end

user.rb

<div class="row center-xs">
    <div class="col-sm-6">
        <h1>New Business</h1>
        <%= simple_form_for @business do |b| %>
            <div class="mdl-textfield mdl-js-textfield">
                <%= b.input :name, label_html: {class: 'mdl-textfield__label'}, input_html: {class: 'mdl-textfield__input'}, required: true, label: "Business Name" %>
            </div><br>
            <%= b.simple_fields_for(resource, :as => resource_name, :url => registration_path(resource_name), validate: true) do |f| %>
                <%= devise_error_messages! %>
                <%= f.input :role, as: :hidden, input_html: { value: "owner" } %>
                <div class="mdl-textfield mdl-js-textfield">
                    <%= f.input :name, label_html: {class: 'mdl-textfield__label'}, input_html: {class: 'mdl-textfield__input'}, required: true, label: "Your Name" %>
                </div><br>
                <div class="mdl-textfield mdl-js-textfield">
                    <%= f.input :email, label_html: {class: 'mdl-textfield__label'}, input_html: {class: 'mdl-textfield__input'}, validate: true, required: true %>
                </div><br>
                <% if @minimum_password_length %>
                    <em>(<%= @minimum_password_length %> characters minimum)</em>
                <% end %>
                <div class="mdl-textfield mdl-js-textfield">
                    <%= f.input :password, label_html: {class: 'mdl-textfield__label'}, input_html: {class: 'mdl-textfield__input'}, autocomplete: "off", required: true %>
                </div><br>
                <div class="mdl-textfield mdl-js-textfield">
                    <%= f.input :password_confirmation, label_html: {class: 'mdl-textfield__label'}, input_html: {class: 'mdl-textfield__input'}, autocomplete: "off", required: true %>
                </div><br>
            <% end %>   
            <%= b.button :submit, "Sign up", class: 'mdl-button' %>
        <% end %>
    </div>
</div>

以下是商业路线的new.html.erb：

 ActiveModel::UnknownAttributeError (unknown attribute 'user' for Business.)

当我尝试创建业务时，我收到一条错误消息：

def create
    @business = Business.new(business_params)

    respond_to do |format|
      if @business.save
        format.html { redirect_to @business, notice: 'Business was successfully created.' }
        format.json { render :show, status: :created, location: @business }
      else
        format.html { render :new }
        format.json { render json: @business.errors, status: :unprocessable_entity }
      end
    end
  end
# Never trust parameters from the scary internet, only allow the white list through.
    def business_params
  params.require(:business).permit(:name, :user => [:email, :name, :password, :password_confirmation])
end

现在控制器只是脚手架生成的默认控制器：

public class TestRestHeartUpdate{
public static void main(String[] args) throws Exception{

URL url;
url = new 
URL("http://127.0.0.1:8080/testDB1/col1/5967c13e61f73b88018db783");

HttpURLConnection hc;
hc = (HttpURLConnection) url.openConnection();
hc.setDoInput(true);
hc.setDoOutput(true);
hc.setRequestMethod("POST");
hc.setRequestProperty("X-HTTP-Method-Override", "PATCH");

hc.setRequestProperty("Content-Type","application/hal+json");
hc.setRequestProperty("Accept","application/hal+json");
hc.setInstanceFollowRedirects(false);
hc.setRequestProperty("If-Match","5967c28f42483b1c3dbedc54");
hc.setUseCaches(false);
hc.connect();

byte[] opB = " {'rating':'VeryGood'}".getBytes("UTF-8");
OutputStream os = hc.getOutputStream();
os.write(opB);
System.out.println(hc.getResponseCode());
}
}

Answer 1

在业务控制器中重命名：permit函数中的用户密钥：users_attributes

params.require(:business).permit(:name, :users_attributes => [:email, :name, :password, :password_confirmation])

创建设备用户和他们所属的关联
