如何在电子邮件的 url_helpers 中包含 ruby​​ on rails 生产挂载点? [英] How to get ruby on rails production mount-point included in url_helpers for email?

问题描述

tl;dnr:我的页面链接没问题，但转换为非页面文本(电子邮件)的链接缺少生产应用挂载点.

tl;dnr: My page links are fine, but links erb-olated into non-page text (email) lack the production app mount-point.

detail:我的 RoR 应用在开发和生产中使用略有不同的 URL:在开发中，顶级实体是资源模型:

detail: My RoR app uses slightly different URLs in dev and production: in dev, the top-level entity is the resource model:

http://localhost:3000/ENTITY/1/edit

但在生产环境中，应用安装在低一级，因此 URLS 有一个额外的术语:

But in production, the app is mounted one level down, so URLS have an extra term:

https://server.example.com/APP/ENTITY/1/edit

这适用于大多数情况:像 edit_entity_url 这样的 url_helpers 返回我显示的 URL.坦率地说，我不清楚它是如何工作的.我想 Phusion 乘客和 Rack 能解决问题吗?

This works fine for most cases: url_helpers like edit_entity_url return the URLs as I've shown them. Frankly, I'm not clear exactly how that works; I suppose Phusion Passenger and Rack work it out?

但是，当我发送电子邮件(例如确认密码重置)时，它不起作用:edit_entity_url 从不添加 APP 挂载点.在 ERB 中缺少我自己的条件逻辑，我怎样才能在那里获得/APP"?

However, when I send email (such as to confirm a password reset), it's not working: edit_entity_url never adds the APP mount-point. Short of my own conditional logic in ERB, how can I get that "/APP" in there?

我尝试过的事情:

• 设置 `Rails.application.routes.default_url_options[:host] 以包含/registry"(无效)
• 使用 <%= link_to 'Reset', edit_entity_url(...) %>(无帮助)

版本信息:

• actionmailer (4.0.2)
• Rails 4.0.2
• 红宝石 2.1.0p0
• 机架 (1.5.2)
• 乘客 (4.0.35)

将事物联系在一起的 Apache启用站点"文件(也是我能找到的唯一定义了/registry"标记的地方):

The Apache "sites-enabled" file that ties things together (and the only place I can find that the "/registry" token is defined):

<VirtualHost *:80>
    ServerName server.example.com
        DocumentRoot /var/www
        <Directory />
                Options FollowSymLinks
                AllowOverride None
        </Directory>
        <Directory /var/www/>
                Options Indexes FollowSymLinks MultiViews
                AllowOverride None
                Order allow,deny
                allow from all
        </Directory>

    Alias /registry /app01/capapp/registry/current/public
    <Location /registry>

    </Location>
    <Directory /app01/capapp/registry/current/public>
        Allow from all

    <Directory "/usr/lib/cgi-bin">

        Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch
        Order allow,deny
        Allow from all
    </Directory>

    ErrorLog ${APACHE_LOG_DIR}/error.log

    LogLevel warn

    CustomLog ${APACHE_LOG_DIR}/access.log combined

    Alias /doc/ "/usr/share/doc/"
    <Directory "/usr/share/doc/">
        Options Indexes MultiViews FollowSymLinks

        Deny from all
        Allow from 127.0.0.0/255.0.0.0 ::1/128
    </Directory>

</VirtualHost>

Rails config/environments/production.rb 文件.

Registration::Application.configure do
  config.cache_classes = true
  config.eager_load = true
  config.consider_all_requests_local       = false
  config.action_controller.perform_caching = true
  config.serve_static_assets = false
  config.assets.js_compressor = :uglifier
  config.assets.compile = false
  config.assets.digest = true
  config.assets.version = '1.0'
  config.log_level = :debug
  config.i18n.fallbacks = true
  config.active_support.deprecation = :notify
  config.log_formatter = ::Logger::Formatter.new
  Rails.application.routes.default_url_options[:host] = "server.example.com"
end

Registration::Application.config.middleware.use ExceptionNotification::Rack,
:email => {
  :email_prefix => "[Registration]",
  :sender_address => %{"Admin" <[e-mail]>},
  :exception_recipients => %w{[e-mail]}
}

查看电子邮件(app/views/user_mailer/password_reset.text.erb):

To reset your password click the URL below.  

<%= edit_password_reset_url(@user.password_reset_token) %>

If you did not request your password to be reset please ignore this email 
and your password will stay as it is.  

是的，将 URL 基于 reset_token 而不是 user_id 是很奇怪的，但它是在控制器中处理的.基于 Railscast #274

Yes, it's odd to base the URL on the reset_token not the user_id, but it's handled in the controller. Structure based on Railscast #274

推荐答案

您可以将 :script_name 参数传递给 url_for(或其他基于 url_for 的方法)来设置挂载点.我用

You can pass the :script_name parameter to url_for (or other methods based on url_for) to set the mount point. I use

url_for( :only_path => false,
:host => some.host,
:script_name => Rails.application.config.relative_url_root
...

并在配置中设置 config.relative_url_root = '/your-mount-point'.

and set config.relative_url_root = '/your-mount-point' in the config.
