Question

我正在制作一个带有一个控制器的网站＆＃34; Projects＆＃34;我希望将所有项目显示到路线：

/ admin / projects /：id = / admin / projects / 1（works）
/ front /：id = /front.1（没有工作）

我在route.rb中尝试了这个

get 'front/:id' => 'projects#show', :constraints => { :id => /[^/]+/ }

，但它不起作用。

我的档案：

的routes.rb

Rails.application.routes.draw do

  resources :users, path: '/admin/clients'

  get 'admin' => 'admin#dashbord'

  get 'admin/profile'

  get 'admin/settings'

  get 'admin/_admin_header'

  get 'front' => 'front#index'

  get 'front/profile' => 'front#profile'

  get 'front/:id' => 'projects#show'

  scope '/admin' do
    resources :projects do
      resources :pictures
    end
  end

  end

projects_controller.rb

  layout 'adminApplication'
  before_action :set_project, only: [:show, :edit, :update, :destroy]


  def index
    @projects = Project.all
  end


  def show
  end


  def new
    @project = Project.new
  end


  def edit
  end


  def create
    @project = Project.new(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 update
    respond_to do |format|
      if @project.update(project_params)
        format.html { redirect_to @project, notice: 'Project was successfully updated.' }
        format.json { render :show, status: :ok, location: @project }
      else
        format.html { render :edit }
        format.json { render json: @project.errors, status: :unprocessable_entity }
      end
    end
  end


  def destroy
    @project.destroy
    respond_to do |format|
      format.html { redirect_to projects_url, notice: 'Project was successfully destroyed.' }
      format.json { head :no_content }
    end
  end

  private

    def set_project
      @project = Project.find(params[:id])
    end


    def project_params
      params.require(:project).permit(:name, :date, :location, :integer)
    end
end

front_controller.rb

  def index
    @projects = Project.all
    render 'projects/index'
  end

  def show
  end

  def profile
  end
end

in projects / index.html.erb

- link_to 'Show', project
- link_to 'Show', front_path(project)

我已经检查了所有类似的问题。

感谢您的帮助！

$out = []; foreach($trainers as $trainerId=> $trainerName){ $out[] = array( 'id'=>$trainerId, 'name'=>$trainerName, 'gold'=>isset($gold[$trainerId])?$gold[$trainerId]:0, 'silver'=>isset($silver[$trainerId])?$silver[$trainerId]:0, 'bronze'=>isset($bronze[$trainerId])?$bronze[$trainerId]:0, ); } uasort($out, function($a, $b){ // Here: sort by your algorithm. Here is example: if($a['gold'] != $b['gold']){ return $b['gold'] - $a['gold']; } if($a['silver'] != $b['silver']){ return $b['silver'] - $a['silver']; } return $b['bronze'] - $a['bronze']; }); $placeId = 1; foreach($out as &$info){ $info['place'] = $placeId++; } unset($info); foreach($out as $info){ echo "{$info['place']} place goes to - {$info['name']} ({$info['id']}) as he/she got {$info['gold']} gold medals, {$info['silver']} silver and {$info['bronze']} bronze"; }：

rake routes | grep front

Answer 1

您正在使用命名路线助手，但您没有指定它：

front_path

您可以在自己的路线中看到projects#show rake routes | grep front front GET /front(.:format) front#index front_profile GET /front/profile(.:format) front#profile GET /front/:id(.:format) projects#show不存在：

routes.rb

所以，在你的get 'front/:id' => 'projects#show', as: :custom_front添加助手：

rake routes

现在运行custom_front_path以查看新帮助程序（它应该是- link_to 'Show', custom_front_path(project)）并使用它：

Log.i("GPSTracker GPS","lat : " + latitude + ", long : " + longitude);
Log.i("GPSTracker Net","lat : " + latitude + ", long : " + longitude);

Answer 2

您可能希望将路线更改为

get 'front.:id' => 'projects#show'
