嵌套窗体Rails的问题

Question

我想在同一时间使用嵌套窗体保存在2个表中。我不知道为什么这不会发生。 Rails错误说“1个错误禁止这个人被保存：”为什么法人没有得到Person_id？

模型

class Person < ApplicationRecord 
    has_one :legal_person, dependent: :destroy 
    accepts_nested_attributes_for :legal_person 
end 


class LegalPerson < ApplicationRecord 
    belongs_to :person 
end 

控制器

class PeopleController < ApplicationController 
    before_action :set_person, only: [:show, :edit, :update, :destroy] 

    # GET /people 
    # GET /people.json 
    def index 
    @people = Person.all 
    end 

    # GET /people/1 
    # GET /people/1.json 
    def show 
    end 

    # GET /people/new 
    def new 
    @person = Person.new 
    @person.build_legal_person 
    end 

    # GET /people/1/edit 
    def edit 
    end 

    # POST /people 
    # POST /people.json 
    def create 
    @person = Person.new(person_params) 

    respond_to do |format| 
     if @person.save 
     format.html { redirect_to @person, notice: 'Person was successfully created.' } 
     format.json { render :show, status: :created, location: @person } 
     else 
     format.html { render :new } 
     format.json { render json: @person.errors, status: :unprocessable_entity } 
     end 
    end 
    end 

    # PATCH/PUT /people/1 
    # PATCH/PUT /people/1.json 
    def update 
    respond_to do |format| 
     if @person.update(person_params) 
     format.html { redirect_to @person, notice: 'Person was successfully updated.' } 
     format.json { render :show, status: :ok, location: @person } 
     else 
     format.html { render :edit } 
     format.json { render json: @person.errors, status: :unprocessable_entity } 
     end 
    end 
    end 

    # DELETE /people/1 
    # DELETE /people/1.json 
    def destroy 
    @person.destroy 
    respond_to do |format| 
     format.html { redirect_to people_url, notice: 'Person was successfully destroyed.' } 
     format.json { head :no_content } 
    end 
    end 

    private 
    # Use callbacks to share common setup or constraints between actions. 
    def set_person 
     @person = Person.find(params[:id]) 
    end 

    # Never trust parameters from the scary internet, only allow the white list through. 
    def person_params 
     #params.require(:person).permit(:nome, :tipopessoa, :telefonefixo, :telefonecelular) 
     params.require(:person).permit(:nome, :tipopessoa, :telefonefixo, :telefonecelular, 
            legal_person_attributes: LegalPerson.attribute_names.map(&:to_sym)) 
            #legal_person_attributes: [:id, :cnpj, :nomefantasia, :person_id]) 
    end 
end

Answer 1

使用属性名的[:cnpj, :nomefantasia]代替

LegalPerson.attribute_names.map(&:to_sym)
