Question

（Rails Newbie here）我有两种型号Usuario和Ficha。 Usuario与Ficha有一个联合。

以下是我的模特：

class Ficha < ApplicationRecord
 belongs_to :user
 belongs_to :usuario
end

class Usuario < ApplicationRecord
 belongs_to :user
 has_one :ficha, :dependent => :destroy
end

这是Usuario控制器：

    class UsuariosController < ApplicationController
      before_action :authenticate_user!
      def index
        @usuarios = Usuario.all
        @usuario_last = Usuario.last(10)
        @usuario_rev = @usuario_last.reverse
        @user_count = current_user.usuarios

        #Search
        @usuario_search = if params[:term]
          Usuario.where("name ~* ?", params[:term])
        else
          Usuario.all
        end
        @usuario_pag = @usuario_search.paginate(:page => params[:page], :per_page => 10)
      end

      def show
        @usuario = Usuario.find(params[:id])
      end

      def new
        @usuario = current_user.usuarios.build
      end

      def create
        @usuario = current_user.usuarios.build(usuario_params)

        @usuario.save
        redirect_to @usuario
      end

      def edit
        @usuario = Usuario.find(params[:id])
      end

      def update
        @usuario = Usuario.find(params[:id])

        if @usuario.update(usuario_params)
          redirect_to @usuario
        else
          render 'edit'
        end
      end

      def destroy
        @usuario = Usuario.find(params[:id])
        @usuario.destroy

      redirect_to usuarios_path
      end

      private
        def usuario_params
          params.require(:usuario).permit(:name, :age, :doc, :docnum, :estadocivil, :country, :street,
          :direction, :municipal, :zipcode, :tel1, :tel2)
        end
    end

这是我的Ficha控制器：

    class FichasController < ApplicationController
      before_action :authenticate_user!
      def index
      end

      def show
        @ficha = Ficha.find(params[:id])
      end

      def new
        @usuario = Usuario.find(params[:usuario_id])
        if @usuario.ficha.nil?
          @ficha = @usuario.build_ficha
        else
          flash[:error] = "Ya tienes una ficha"
        end
      end

      def create
        @usuario = Usuario.find(params[:usuario_id])

        @ficha = @usuario.build_ficha(ficha_params)
        if @ficha.save
          redirect_to @usuario, :notice => "Your ficha has been successfully created."
        else
          render :action => 'new'
        end
      end

      def edit
        #@ficha = Ficha.find(params[:id])
      end

      def update
        @ficha = Ficha.find(params[:id])

            if @ficha.update(ficha_params)
                redirect_to @ficha
            else
                render 'edit'
            end
      end

      def destroy

        @usuario = Usuario.find(params[:usuario])
        @ficha = @usuario.fichas.find(params[:id])
        @ficha.destroy

      redirect_to fichas_path
    end

    private
      def ficha_params
        params.require(:ficha).permit(:name, :age, :doc, :docnum, :estadocivil, :country, :street,
        :direction, :municipal, :zipcode, :tel1, :tel2, :time, :redes, :estudios, :profession,
        :laboral, :discapacity, :percent, :derivado1, :derivado2, :derivacion, :nombredelprofesional,
        :observaciones, :conocio, :signature, :date, :term)
      end
    end

我在控制器中创建ficha的某个地方出错了吗？在usuario模型中使用after_create后立即创建对象会更好吗？

任何帮助表示赞赏！谢谢！

是的，你以正确的方式解决这个问题。如果您的<script type='text/javascript'> var zoneMap; var currentRestMarkers = []; var markerInfoWindow; var distances = [{"fee":2,"distance":5,"available":1},{"fee":3,"distance":7,"available":1},{"available":1,"distance":9,"fee":7},{"fee":9,"available":0,"distance":10}];

查看debugging with the console命令，了解如何解决这些类型的问题，方法是在保存尝试后插入@ficha以查看console对象是否附加了任何错误

Answer 2

在Rails 4.2.1中

我在这里看不到你使用了＃accepted; accepts_nested_attributes_for＆＃39;。阅读http://api.rubyonrails.org/classes/ActiveRecord/NestedAttributes/ClassMethods.html

试试这些

class Ficha < ApplicationRecord
 belongs_to :user
 belongs_to :usuario
end

class Usuario < ApplicationRecord
 belongs_to :user
 has_one :ficha, :dependent => :destroy
 accepts_nested_attributes_for :ficha
end

你也可以在UsuariosController中使用ficha_attributs，就像这些

一样

private
  def usuario_params
     params.require(:usuario).permit(:name, :age, :doc, :docnum, :estadocivil, :country, :street,:direction, :municipal, :zipcode, :tel1, :tel2, ficha_attributes: [# Write ficha attributes you want save])
  end

为什么我的关联对象无法保存？
