rails4多站点显示主机 - 有时可以工作 [英] rails4 multisite show host in view - sometimes works

问题描述

我已经在这个整个下午工作了......

我在heroku上有一个codebase多个应用程序设置。我试图在主域名（stati_controller）上显示主机：www.domain.hu（env：production，production.rb），但不在另一个主域上：www.domain.co。 uk（env：production-uk，production-uk.rb）
Debug告诉我：无
我错过了什么？

基于< a href =https://stackoverflow.com/questions/2660172/how-do-i-set-default-host-for-url-helpers-in-rails>这个和这我尝试了以下但没有运气（一个接一个地尝试......）。在 production-uk.rb 中：

  Rails.application.default_url_options [：host] ='www .domain.co.uk'
 Rails.application.default_url_options [：host] ='domain.co.uk'
 config.asset_host ='www.domain.co.uk' - 这个杀死 CSS 
 config.default_url_options = {host：'www.domain.co.uk'} 
 config.default_url_options [：host] ='domain.co.uk'
 config.action_controller。 default_url_options = {host：'www.domain.co.uk'} 
 config.action_controller.default_url_options = {host：'domain.co.uk'} 
 Rails.application.default_url_options = {host：' domain.co.uk'} 
 config.action_controller.default_url_options = {host：'domain.co.uk'} 
 config.action_controller.default_url_options [：host] ='domain.co.uk'
 host ='www.domain.co.uk'
 config.action_controller.default_url_options = {host：host} 
  

我也在 static_pages_controller.rb - 没有运气（带或不带过滤器）：

  def default_url_options 
如果Rails.env == 'production'
 {：host => www.domain.hu} 
 elsif Rails.env =='production-uk'
 {：host => www.domain.co.uk} 
 else 
 {} 
 end 
 end 
  

和基于request.host的验证工作罚款，所以我不明白（static_pages_controller.rb）：

  before_filter：验证
 ... 
 def验证
 domain = request.host 
 if domain =='www.domain。 hu'
 authenticate_or_request_with_http_basic do |用户名，密码|用户名=='东西'&&密码=='boda'
结束
 elsif域=='www.domain.co.uk'
 authenticate_or_request_with_http_basic do |用户名，密码|用户名=='东西'&&密码=='boda'
结束
结束
结束
  

我在production-uk.rb中也有这样的作品：

  host ='www.domain.co.uk'
 config.action_mailer.default_url_options = {host：host} 
  

更新
还有一件事：当我在应用程序的heroku控制台中写入app.host时，答复始终为www.example.com。

感谢您阅读！

解决方案

这是一个严峻的错误。我有

  @host = request.host 
  

在static_pages_controller.rb中的gmaps4rails的位中

这就是为什么它不总是工作.... grr p>

Have been working on this all afternoon now...

I have a one codebase multiple apps setup on heroku. I am trying to display the host on the home page (stati_controller) which works on my main domain: www.domain.hu (env: production, production.rb) but doesn't on the other one: www.domain.co.uk (env: production-uk, production-uk.rb) Debug tells me: nil What am I missing?

Based on this and this I tried the followings but no luck (tried one-by-one...). In production-uk.rb:

Rails.application.default_url_options[:host] = 'www.domain.co.uk'
Rails.application.default_url_options[:host] = 'domain.co.uk'
config.asset_host = 'www.domain.co.uk' - this "kills" the CSS 
config.default_url_options = { host: 'www.domain.co.uk' }
config.default_url_options[:host] = 'domain.co.uk'
config.action_controller.default_url_options = { host: 'www.domain.co.uk' }
config.action_controller.default_url_options = { host: 'domain.co.uk' }
Rails.application.default_url_options = { host: 'domain.co.uk' }
config.action_controller.default_url_options = { host: 'domain.co.uk' }
config.action_controller.default_url_options[:host] = 'domain.co.uk'
host = 'www.domain.co.uk'
  config.action_controller.default_url_options = { host: host }

I also tried this in static_pages_controller.rb - no luck (with or without before-filter):

  def default_url_options
    if Rails.env == 'production'
      {:host => "www.domain.hu"}
    elsif Rails.env == 'production-uk'
      {:host => "www.domain.co.uk"}
    else  
      {}
    end
  end 

And authenticate works based on request.host fine so I don't understand (static_pages_controller.rb):

before_filter :authenticate
...
def authenticate
domain = request.host
if domain == 'www.domain.hu' 
authenticate_or_request_with_http_basic do |username, password| username == 'stuff' && password == 'boda'
  end
elsif domain == 'www.domain.co.uk'
authenticate_or_request_with_http_basic do |username, password| username == 'stuff' && password == 'boda'
end
end
end

I have this in production-uk.rb too that works:

host = 'www.domain.co.uk'
config.action_mailer.default_url_options = { host: host }

UPDATE There is one more thing: When I am in the heroku console of the app and write app.host the reply is always "www.example.com"

Thanks for reading!

解决方案

It was a stvpid mistake. I had

@host = request.host

inside the gmaps4rails's bit in the static_pages_controller.rb

That's why it didn't always work.... grr
