Question

我正在构建一个多租户网站，并使用Ryan Bigg的https://leanpub.com/multi-tenancy-rails作为指南。我坚持创建一个简单的范围路线;我一直收到错误Rails 5 Routing Error - uninitialized constant DashboardController。我确信我遗漏了一些简单的东西，因为语法自出版物的最终版本发生了一些变化。我的代码下面是否应该如此 - 现在我只是想要显示仪表板索引页面？

控制器/帐户/ base_controller.rb

 module Accounts
   class BaseController < ApplicationController
     before_action :authenticate_user!
   end
 end

控制器/帐户/ dashboard_controller.rb

module Accounts
  class DashboardController < Accounts::BaseController
    def index
    end
  end
end

视图/帐户/仪表板/ index.html.rb

<section class="bg--secondary space--sm conversation">
  <div class="container">
    <div class="row">
      <div class="col-md-6">
        <h1>Dashboard</h1>
      </div>
    </div>
  </div>
</section>

的routes.rb

constraints(SubdomainRequired) do
  scope module: 'accounts' do
    root to: 'dashboard#index', as: :account_root
  end
end

Rails.application.routes.draw do
  devise_for :users

  constraints(SubdomainRequired) do
    root to: 'dashboard#index', as: :account_root
  end

  get '/accounts/new', to: 'accounts#new', as: :new_account
  post '/accounts', to: 'accounts#create', as: :accounts
  root 'welcome#index'
end

Answer 1

我很快就制作了多租户项目，并将lvh.me用于开发环境。尝试以下解决方案：

<强>配置/初始化/ subdomain_constraint.rb

class SubdomainConstraint
  def initialize
    @domain_development = 'lvh.me'
  end

  def matches?(request)
    if Rails.env.development?
      @domain_development == request.domain
    end
  end
end

<强>的routes.rb

constraints(SubdomainConstraint.new) do
      match '', to: 'dashboard#index', constraints: {subdomain: /.+/}, via: [:get]
end

Answer 2

我不确定您是否可以在routes.rb文件中定义一个类。也许如果您创建一个名为lib/subdomain_required.rb并移动

的新文件

class SubdomainRequired
  def self.matches?(request)
    request.subdomain.present? && request.subdomain != 'www'
  end
end

到该文件，而不是将其放入routes.rb。
