如何将 Current_User 添加到嵌套属性？

Question

date_value
result_value

None 以上属性在我加载索引页时显示。

我知道是因为这一行：<% if averaged.user == current_user %>

更具体地说，这是因为 date_value 和 result_value 的嵌套属性（因为如果我取出这些嵌套属性，名称和指标将显示）

我需要向控制器添加什么才能让嵌套属性显示在索引页上，并且实际上所有属性都有效？

提前感谢您的服务！

<div id="values" class="panel panel-default">
  
  <div class="panel-heading"><h4><b>AVERAGE</b></h4></div>

  <!-- Table -->
<table>
  <% @averaged_quantifieds.each do |averaged| %>
    <% if averaged.user == current_user %>
        <th class="value">
          <%= link_to edit_quantified_path(averaged) do %>
          <%= averaged.name %>
          <% end %>
          (<%= averaged.metric %>)
        </th>
      <tbody class="value"> 
          <td><%= averaged.date_value.strftime("%m-%Y") %></td>
          <td><%= averaged.result_value %></td>
      </tbody>
    <% end %>
  <% end %>
</table>
</div>

控制器

class QuantifiedsController < ApplicationController
  before_action :set_quantified, only: [:show, :edit, :update, :destroy]
  before_action :authenticate_user!, except: [:index, :show]

  def index
   @averaged_quantifieds = current_user.quantifieds.averaged
   @instance_quantifieds = current_user.quantifieds.instance
   @averaged_quantifieds = Result.all.order("date_value")
   @instance_quantifieds = Result.all.order("date_value")
  end

  def show
  end

  def new
    @quantified = current_user.quantifieds.build
    @quantified = Quantified.new
  end

  def edit
  end

  def create
    @quantified = current_user.quantifieds.build(quantified_params)
    if @quantified.save
      redirect_to quantifieds_url, notice: 'Quantified was successfully created'
    else
      render action: 'new'
  end
end

  def update
    if @quantified.update(quantified_params)
      redirect_to quantifieds_url, notice: 'Goal was successfully updated'
    else
      render action: 'edit'
  end
end

  def destroy
    @quantified.destroy
    redirect_to quantifieds_url
  end

  private
    def set_quantified
      @quantified = Quantified.find(params[:id])
    end

    def correct_user
      @quantified = current_user.quantifieds.find_by(id: params[:id])
      redirect_to quantifieds_path, notice: "Not authorized to edit this goal" if @quantified.nil?
    end

    def quantified_params
      params.require(:quantified).permit(:categories, :name, :metric, :result, :date, results_attributes: [:id, :result_value, :date_value, :_destroy])
    end
end

quantified.rb

class Quantified < ActiveRecord::Base
 belongs_to :user
  scope :averaged,  -> { where(categories: 'averaged') }
  scope :instance,  -> { where(categories: 'instance') }
  has_many :results
 accepts_nested_attributes_for :results, :reject_if => :all_blank, :allow_destroy => true

 CATEGORIES = ['averaged', 'instance']

end

希望这能为您指明正确的方向

这对我来说很奇怪

  def index
   @averaged_quantifieds = current_user.quantifieds.averaged 
   @instance_quantifieds = current_user.quantifieds.instance
   @averaged_quantifieds = Result.all.order("date_value")
   @instance_quantifieds = Result.all.order("date_value")
  end

你定义了这两个并且基本上互相覆盖了？

如果您的属性没有显示，则与嵌套无关，与逻辑有关。所以换句话说，这个逻辑

if averaged.user == current_user

未计算为真，因此请检查每个对象实际包含的内容。您可以通过在视图中检查它来以肮脏的方式执行此操作

例如放 <%= averaged.user.inspect %> 和 <%= current_user.inspect %>

一旦您知道它持有什么对象，请在您的代码中回溯到您如何将它们更改为该状态。我怀疑它会返回到您遇到问题的控制器。
