问题描述
我正在使用一种相当传统的忘记密码电子邮件-我想通过电子邮件将隐藏在链接中的密码更改令牌发送给用户,用户可以单击该令牌来更改密码。我通过传统的ActionMailer发送电子邮件。
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.
如果我使用普通的link_to标签
If I use a normal link_to tag
<%= link_to "click here", :controller => foo, :action => 'bar', :token => token %>
我得到了一个相对链接-电子邮件中没有用。
I get a relative link - rather useless from an email.
如果我添加
:only_path => false
,然后出现错误,提示我需要设置 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。肯定有一个配置选项可以告诉Rails的主机名是什么,而无需添加我自己的配置文件,对其进行解析等?
: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?
推荐答案
default_url_options
可从 config.action_mailer
获得,并且应在您环境的配置文件中进行设置。
default_url_options
is available from config.action_mailer
and should be set in your environment's configuration file.
例如,在 config / environments / production.rb
:
config.action_mailer.default_url_options = {
:host => 'www.yourdomain.com'
}
对于本地测试,请修改 config / environments / development.rb
:
For local testing, modify config/environments/development.rb
:
config.action_mailer.default_url_options = {
:host => '127.0.0.1',
:port => 3000
}
然后,假设您有一个名为的命名路由forgot_password_login
,您可以使用以下方式在邮件程序中生成登录链接URL:
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:
forgot_password_login_url(:token => 'a7s8q15sk2...')
