CRUD index.html.erb，new.html.erb，編輯等頁面未顯示？ Ruby 上軌

Question

目前我的 index.html、new.html.erb 等文件中沒有任何內容正在加載。 例如，如果我輸入 http://localhost:3000/teams/new 或 http://localhost:3000/teams，除了我的導航欄加載之外什么都沒有。

這是我的teams_controller.rb

class TeamsController < ApplicationController
  before_action :set_team, only: [:show, :edit, :update, :destroy]

  # GET /teams
  # GET /teams.json
  def index
    @teams = Team.all.sort_by {|t| t.total_points}
  end

  # GET /teams/1
  # GET /teams/1.json
  def show
    @team_roster = User.for_team(@team).by_first_name
  end

  # GET /teams/new
  def new
    @team = Team.new
  end

  # GET /teams/1/edit
  def edit
  end

  # POST /teams
  # POST /teams.json
  def create
    @team = Team.new(team_params)

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

  # PATCH/PUT /teams/1
  # PATCH/PUT /teams/1.json
  def update
    respond_to do |format|
      if @team.update(team_params)
        format.html { redirect_to @team, notice: 'Team was successfully updated.' }
        format.json { render :show, status: :ok, location: @team }
      else
        format.html { render :edit }
        format.json { render json: @team.errors, status: :unprocessable_entity }
      end
    end
  end

  # DELETE /teams/1
  # DELETE /teams/1.json
  def destroy
    if @team.destroy
      flash[:notice] = "Successfully removed #{@team.name}."
      redirect_to teams_url
    else
      @team_roster = User.for_team(@team.id).by_first_name
      render action: 'show'
    end
  end

  private
    # Use callbacks to share common setup or constraints between actions.
    def set_team
      @team = Team.find(params[:id])
    end

    # Only allow a list of trusted parameters through.
    def team_params
      params.require(:team).permit(:name, :description, :active)
    end
end

這是我的application.html.erb

<!DOCTYPE html>
<html>
  <head>
    <title>ACFQuarantineChallenge</title>
    <meta name="viewport" content="width=device-width, initial-scale=1">

    <%= csp_meta_tag %>



    <%= stylesheet_link_tag    'application', media: 'all', 'data-turbolinks-track': 'reload' %>

  </head>

  <body>
  <%= render :partial => "partials/nav" %>
  </body>
</html>

這是我團隊索引的片段index.html.erb

<% if @teams.empty? %>
  <h4>There are no teams in the system at this time.</h4>
<% else %>

  <h1>Teams</h1>

  <table>
    <thead>
      <tr>
        <th>Name</th>
        <th>Description</th>
        <th>Active</th>
        <th colspan="3"></th>
      </tr>
    </thead>

    <tbody>
      <% @teams.each do |team| %>
        <tr>
          <td><%= team.name %></td>
          <td><%= team.description %></td>
          <td><%= team.active %></td>
          <td><%= link_to 'Show', team %></td>
          <td><%= link_to 'Edit', edit_team_path(team) %></td>
          <td><%= link_to 'Destroy', team, method: :delete, data: { confirm: 'Are you sure?' } %></td>
        </tr>
      <% end %>
    </tbody>
  </table>

  <br>

  <%= link_to 'New Team', new_team_path %>

<%end%>

我已經嘗試過輸入像“Hello World”這樣的虛擬文本，但即使這樣也沒有渲染。 任何幫助，將不勝感激！

Answer 1

看起來您已經從application.html.erb文件中刪除了yield 。 在<%= render:partial => "partials/nav" %> <%= yield %> > 。

<%= yield %>將呈現當前控制器#action 的模板。

您可以在此處閱讀有關產量的更多信息。

Answer 2

您尚未在布局文件中添加yield ，即application.html.erb您應該在正文或_nav.html.erb中添加<%= yield %> ，具體取決於您的頁面樣式。
