How do I configure the hostname for Rails ActionMailer?
提问by edebill
I'm working on a fairly traditional forgot password email - I want to email the user a password change token embedded in a link that they can click on in order to change their password. I'm emailing via the traditional ActionMailer.
我正在处理一个相当传统的忘记密码电子邮件 - 我想通过电子邮件向用户发送一个嵌入在链接中的密码更改令牌，他们可以单击该令牌以更改其密码。我通过传统的 ActionMailer 发送电子邮件。
If I use a normal link_to tag
如果我使用普通的 link_to 标签
<%= link_to "click here", :controller => foo, :action => 'bar', :token => token %>
I get a relative link - rather useless from an email.
我得到一个相对链接 - 从电子邮件中相当无用。
If I add in
如果我加入
:only_path => false, then it errors saying I need to set default_url_options[:host]. The ActionController docs imply that you do that by overriding the #default_url_options methods in your controller. Surely there's a configuration option to tell Rails what it's hostname is without adding my own config file, parsing it, etc?
:only_path => false，然后它错误说我需要设置default_url_options[:host]. ActionController 文档暗示您可以通过覆盖控制器中的 #default_url_options 方法来做到这一点。当然有一个配置选项可以告诉 Rails 它的主机名是什么，而无需添加我自己的配置文件、解析它等？

default_url_optionsis available from config.action_mailerand should be set in your environment's configuration file.
default_url_options可从config.action_mailer您的环境的配置文件中获得并应在其中进行设置。
For example, in config/environments/production.rb:
例如，在config/environments/production.rb：
config.action_mailer.default_url_options = {
:host => 'www.yourdomain.com'
}
For local testing, modify config/environments/development.rb:
对于本地测试，修改config/environments/development.rb：
config.action_mailer.default_url_options = {
:host => '127.0.0.1',
:port => 3000
}
Then, assuming you have a named route called forgot_password_login, you can generate the login link URL in your mailer using something like this:
然后，假设您有一个名为 的命名路由forgot_password_login，您可以使用以下内容在您的邮件程序中生成登录链接 URL：
forgot_password_login_url(:token => 'a7s8q15sk2...')

You probably want to set :protocol => 'https' as well, btw.
您可能还想设置 :protocol => 'https' ，顺便说一句。
config.action_mailer.default_url_options = {
:host => "portal.example.com",
:protocol => 'https'
}

There is another alternative, as described in http://pivotallabs.com/how-i-leaned-to-stop-hating-and-love-action-mailer/
还有另一种选择，如http://pivotallabs.com/how-i-leaned-to-stop-hating-and-love-action-mailer/ 中所述
This solution has the advantage that it doesn't require any configuration (so less of a hassle), and works fine as long as you send emails from within controllers.
这个解决方案的优点是它不需要任何配置（因此不那么麻烦），并且只要您从控制器内部发送电子邮件就可以正常工作。
But if you plan on sending email without going through a controller (e.g. from command line or in response to another email), you need the static configuration.
但是，如果您计划不通过控制器（例如从命令行或响应另一封电子邮件）发送电子邮件，则需要静态配置。

Setting default_url_optionsdirectly is deprecated in Rails 3.1. Use url_forinstead.
default_url_optionsRails 3.1 中不推荐直接设置。改用url_for。
Add parameter :protocolto override default value (http), :protocol => 'https://'. This will create url starting with "https://..." instead of default "http://"
添加参数:protocol以覆盖默认值 (http), :protocol => 'https://'. 这将创建以“https://...”开头的网址，而不是默认的“http://”

Interestingly, I had the same issue as you did, but in unit tests (while following Michael Hartl's railstutorial). I had this line in my test.rb file, but that didn't help:
有趣的是，我和你有同样的问题，但在单元测试中（同时遵循 Michael Hartl 的 railstutorial）。我的 test.rb 文件中有这一行，但这没有帮助：
config.action_mailer.default_url_options = { host: 'example.com', protocol: 'http' }
I've also added another line like this to test.rb, and surprisingly this solved the issue
我还在 test.rb 中添加了另一行这样的行，令人惊讶的是这解决了这个问题
default_url_options = { host: 'example.com', protocol: 'http' }

Rails 3.1 中不推荐直接设置 default_url_options
Use the url_for helper to create it:
使用 url_for 助手来创建它：
<%= link_to "click here", url_for(:controller => foo, :action => 'bar', :token => token, :host => 'www.yourdomain.com') %>

Can you just do
你能做吗
<%="click here", :controller => foo, :action => 'bar', :token => token, :host=>request.host -%>
