Question

我目前有以下型号：

user.rb

    class User < ApplicationRecord
      has_one :profile, dependent: :destroy
      before_create :build_profile 
    end

profile.rb

    class Profile < ApplicationRecord
      belongs_to :user  
      delegate :name, :email, :name=, :email=, to: :user
    end

对于个人资料，我有以下控制器：

profile_controller.rb

    class ProfileController < ApplicationController

      before_action :set_user
      before_action :authenticate_user!

      def edit
        @user = current_user
        @profile = @user.profile
      end

      def update
        @user = current_user
        @profile = @user.profile

        if @profile.update(profile_params)
          redirect_to profile_path(current_user.username)
        else
          render :edit
        end
      end

      private

      def profile_params
         params.require(:profile).permit(:name, :email, :user_id, :bio, :avatar, :remove_avatar) 
      end

    end

我的“编辑个人资料”表单如下：

edit.html.haml

    = simple_form_for @profile do |f|
      = f.error_notification
      .form-inputs
        .row
          .col-md-6.col-sm-12
            = f.input :name, required: true, placeholder: "Name"
          .col-md-6.col-sm-12
            = f.input :email, required: true, placeholder: "Email"
        = f.input :bio, required: true, hint: "Write a short bio about yourself", placeholder: "PHP Developer developing cool apps in Tokyo."
        = f.input :avatar, as: :attachment, direct: true, presigned: true
      .form-actions
        = f.button :submit, "Update", class: "btn ban-info"

我正在尝试更改配置文件表单中的委托值。但是，它们不会持久存储到数据库中。我该怎么做呢？

代替通常为暴露不涉及持久性的公共方法而保留的委托，请尝试将以下行添加到配置文件模型中：

accepts_nested_attributes_for :user #This will allow you to handle user attributes via a profile object

此外，在您的update操作中，您需要指定个人资料和用户的关系，例如：

if @user.profile.update_attributes(profile_params)

如何在rails中保留委派字段的值
