Ruby on rails 如何在rails中呈现表及其关联项目

我已经在rails中创建了脚手架项目和舞台。两者在rails中都有多对一关联。就像每个项目将有多个阶段，用户将有多个项目。我能够渲染项目将关联的用户id，但舞台将在每个用户上渲染。我能解决这个问题吗

project.rb

  has_many :stages

stage.rb

  belongs_to :project

project show.html.erb，我在其中渲染项目的阶段

<div class="table-scroll">
  <table>
    <thead>
      <tr>
        <th>Stage</th>
        <th>Responsibility</th>
        <th>Status</th>
        <th>Finance</th>
      </tr>
    </thead>

    <tbody>
      <% @stages.each do |stage| %>
        <tr>
          <td><%= stage.stage %></td>
          <td><%= stage.responsibility %></td>
          <% if stage.status == true %>
            <td class="completed"><%= "Completed" %></td>
          <% elsif stage.status == false %>
            <td class="in-progress"><%= "In-Progress" %></td>
          <% else %>
            <td class="yet-to-start"><%= "Yet to Start" %></td>
          <% end %>
          <td><%= stage.finance %></td>

        </tr>
      <% end %>
    </tbody>
  </table>
</div>

stages\u controller.rb

def index
    @projects = current_user.projects.all.paginate(page: params[:page], per_page: 15)
  end

  def show
    @project=Project.find(params[:id])
    @stages = Stage.all
  end

  def new
    @project = current_user.projects.build
  end

  def create
    @project = current_user.projects.build(project_params)

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

  def index
    @stages = Stage.all
  end

  def show
  end

  def new
    @stage = Stage.new
    @project = Project.find(params[:project_id])
  end


  def create
    @project = Project.find(params[:project_id])
    @stage = @project.stages.build(stage_params)

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

我希望舞台只呈现给他们的相关项目。我需要做哪些更改？

在旁注中-不要将布尔值用作状态。这是一个可怕的db设计选择。一个字符串、一个整数或其他任何东西，甚至多个布尔列都是更好的选择。特别是因为您似乎使用了空状态，这意味着它甚至不是真正的布尔值。@max感谢您的建议。

def show
  @project = Project.includes(:stages).find(params[:id])
  @stages = @project.stages
end
