公寓红宝石宝石:想赶上例外

Question

我正在使用这间公寓一颗红宝石.

我在application.rb文件中添加了这个:

config.middleware.use 'Apartment::Elevators::Subdomain'

当我尝试在浏览器url'test.domain.local:3000'中点击此内容时,PostgreSQL中不存在子域'test'架构,我看到此错误

Apartment::SchemaNotFound (One of the following schema(s) is invalid: test, "public")

我知道这是gem的正常行为但是想要捕获这个异常并将用户重定向到其他页面,我该怎么做？

Answer 1

这就是我做的:

在lib/rescued_apartment_middleware.rb下创建文件

module RescuedApartmentMiddleware
  def call(*args)
    begin
      super
    rescue Apartment::TenantNotFound
      Rails.logger.error "ERROR: Apartment Tenant not found: #{Apartment::Tenant.current.inspect}"
      return [404, {"Content-Type" => "text/html"}, ["#{File.read(Rails.root.to_s + '/public/404.html')}"] ]
    end
  end
end

并按以下行添加到您的Apartment初始化程序文件中:

require 'rescued_apartment_middleware'

Rails.application.config.middleware.use 'Apartment::Elevators::Subdomain'
Apartment::Elevators::Subdomain.prepend RescuedApartmentMiddleware

这就像一个魅力!(用ruby 2.1和Rails 4.1测试)
