Question

计划（对象）

    #<Program id: 1, country: "UK", title: "Bee Movie", subtitle: "Born to bee wild.", 
description: "Barry B. Benson, a bee who has just graduated from ...", official_rating: 6.1,
 rating: 6.1, ptype: "movie", year: "2007", imdb: "0389790", tmdb: "5559", tvdb: nil, wiki:

程序（模型）

class Program < ActiveRecord::Base
 attr_accessor :subdomain

 def subdomain
     'something elaborated'
  end
end

的routes.rb

 scope ":subdomain" do
     resources :programs
   end

现在，如果我称之为

p = Program.first
program_path(p)

我得到了

ActionController::UrlGenerationError: No route matches {:locale=>:en, :action=>"show", :controller=>"programs", :id=>nil, :format=>nil} missing required keys: [:subdomain, :id]

我在我的模型中设置了attr_accessor。还缺少什么？

我的网址应为：http://example.com/uk/programs/1-bee-movie

顺便说一句，由于原因，我打电话给'：subdomain'。因为在它之前是uk.example.com，但现在，对于seo，应该是example.com/uk

Answer 1

routes.rb

scope "/(:subdomain)" do
    resources :programs
end

视图文件

program_path(program, :subdomain => 'uk')

Answer 2

解决。

使用：子域与Rails的“子域”冲突

url program_url(p, :country_prefix => 'uk')

通过动态属性编辑resource_path
