Question

我是Ruby on rails和构建应用程序的新手，用户可以在注册后添加他的教育历史记录。我使用两个编辑表单，一个默认设计编辑视图用于密码或电子邮件更新，第二个编辑用户视图，我与users_controller一起创建用于更新其他字段，如名称等。我使用嵌套表单添加教育详细信息。问题是如何初始化教育模型，因为我希望用户在注册后添加教育详细信息。我不希望用户在注册字段中提示用户使用所有这些字段。没有错误，但没有教育领域。

主要问题是我使用设计注册和自定义编辑表单来添加教育字段。我需要编写自定义新方法吗？

这是我的app / views / users / edit.html.erb

中的代码

        <div class="input-field">
             <%= f.label :name %>
             <%= f.text_field :name %>
         </div>

        <div class="input-field">
            <%= f.label :date_of_birth %><br />
            <%=f.date_field(:date_of_birth, :class => "datepicker")%>
        </div>


        <div class="input-field">
            <%= f.label :city %><br />
            <%= f.text_field :city, autofocus: true %>
        </div>

         <div class="input-field">
            <%= f.label :about_me %>
            <%= f.text_area :about_me, autofocus: true %>
        </div>

        <%= f.fields_for :educations do |ff| %>
            <div>
                <%= ff.label :institution_name %>
                <%= ff.text_field :institution_name %>
            </div>

            <div>
                <%= ff.label :course %>
                <%= ff.text_field :course %>
            </div>

            <div class="input-field">
                <%= f.label :from %><br />
                <%=f.date_field(:from, :class => "datepicker")%>
            </div>

            <div class="input-field">
                <%= f.label :to %><br />
                <%=f.date_field(:to, :class => "datepicker")%>
            </div>

        <% end %>
        <%= f.submit "Save changes"%>
   <% end %>

这是我的userss_controller.rb

   class UsersController < ApplicationController
   before_action :authenticate_user!
   before_action :prepare_schools
   before_action :correct_user, only: [:edit, :update]

   def new
   end

   def index
     @users = User.all
   end

   def show
     @user= User.find(params[:id])
   end

   def edit
     @user = User.find(params[:id])
   end

   def update
     @user = User.find(params[:id])
     if @user.update_attributes(user_params)
      flash[:success] = "Profile updated"
      redirect_to @user
    else
        render 'edit'
    end
  end

 def correct_user
   @user = User.find(params[:id])
   redirect_to(root_url) unless current_user==(@user)
 end

 private

    def user_params
      params.require(:user).permit(:name,:date_of_birth,:city,:about_me,
          :educations_attributes => [:id,:institution_name, :from, :to])
    end

    def prepare_schools
       @schools = School.all
    end
 end

here is my USER model

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


     enum user_type: [:student, :teacher, :principal, :other]

    has_one :school
    has_many :educations,  dependent: :destroy, inverse_of: :user
    accepts_nested_attributes_for :educations, :allow_destroy => true,
                                  :reject_if     => :all_blank,
                                  :allow_destroy => true

    validates :name, presence: true, length: { maximum: 50 }
    validates :user_type, presence: true, length: { maximum: 50 }
    validates :school_id, presence: true
    validates :date_of_birth, presence: true
    validates :about_me,  length: { maximum: 1000 }
    validates :city,  length: { maximum: 100 }
 end

这是我的教育模式（嵌套模型）

  class Education < ActiveRecord::Base
     belongs_to :user, inverse_of: :educations
     validates_presence_of :user
  end

编辑（由pavan建议）：这是通过表单的参数，嵌套属性不存在

    !ruby/hash:ActionController::Parameters
     utf8: "✓"
     _method: patch
                                                                                    authenticity_token:1gHK22TcGLsPjIdb/
      user: !ruby/hash:ActionController::Parameters
       name: ''
       date_of_birth: '1992-03-03'
       city: delhi
       about_me: i am what i am!!
       commit: Save changes
       controller: users
       action: update
       id: '3'

P.S。我尝试使用formhelper函数，但这没有帮助。

在new或edit操作中，您可以构建educations个对象，它将初始化嵌套属性。如下 -

def new
  current_user.eductions.build #or @user.educations.build
  # it will initialize a eduction object in form

end

如何在注册后使用设计的ROR应用程序中初始化嵌套表单属性？
