Question

我正在关注Sinatra :: Base上本教程中的配方 https://www.safaribooksonline.com/library/view/sinatra-up-and/9781449306847/ch04.html

我在尝试使用我的路线时遇到问题，目前只有一条路线正常工作，get '/'从ApplicationController < Sinatra::Base home.erb加载。

我的第二个控制器中名为ExampleController < ApplicationController的路由不起作用

config.ru （仅限相关代码）

# Load Controllers and models
Dir.glob('./{controllers,models}/*.rb').each { |file| require file }

map('/example') { run ExampleController }
map('/') { run ApplicationController }

application_controller.rb

class ApplicationController < Sinatra::Base
  # set folder for root
  set :root, File.expand_path("../app", Dir.pwd)

  # don't enable logging when running tests
  configure :production, :development do
    enable :logging
  end

  get '/' do
    title "Home.erb"
    erb :home
  end

  not_found do
    title 'Not Found!'
    erb :not_found
  end

end

example_controller.rb ，其中的路线不会从当前加载

class ExampleController < ApplicationController

  get '/example' do
    title "Example Page"
    erb :example
  end

end

根据教程，您看起来在config.ru文件和ExampleController的路由中都使用了路由/example。这可能意味着您的本地网址最终可能会被视为＆＃39; http://localhost:4567/example/example＆＃39; 。根据事物的外观，您的example_controller.rb文件应该如下所示，使用＆＃39; /＆＃39;作为路线：

<强> example_controller.rb

class ExampleController < ApplicationController

  get '/' do
    title "Example Page"
    erb :example
  end

end

您的config.ru文件中似乎还需要require 'sinatra/base'。

<强> config.ru

# Load Controllers and models
require 'sinatra/base'
Dir.glob('./{helpers,controllers}/*.rb').each { |file| require file }

map('/example') { run ExampleController }
map('/') { run ApplicationController }

此外，您的application_controller.rb似乎缺少您的帮助程序，并且未包含设置视图。

<强> application_controller.rb

class ApplicationController < Sinatra::Base
  helpers ApplicationHelper

  # set folder for templates to ../views, but make the path absolute
  set :views, File.expand_path('../../views', __FILE__)

  # don't enable logging when running tests
  configure :production, :development do
    enable :logging
  end

  get '/' do
    title "Home.erb"
    erb :home
  end

  # will be used to display 404 error pages
  not_found do
    title 'Not Found!'
    erb :not_found
  end
end

模块化Sinatra - 路由不工作 - 构建config.ru和多个控制器来处理路由
