设计确认链接将用户重定向到heroku域而不是自定义域 [英] Devise confirm link redirects user to heroku domain not a custom domain

问题描述

我有一个Web应用程序：Angular的前端和Rails的后端。
我有一个自定义域 www.example.com 并将用户重定向到heroku URL（ example.herokuapp.com ）。

I have a web app: front-end in Angular and back-end in Rails. I have a custom domain www.example.com and redirects users to heroku URL(example.herokuapp.com).

用户注册后，他们需要确认电子邮件。当他们从我的Web应用程序收到电子邮件时，他们单击链接。我使用Devise顺便确认用户的电子邮件。
应该将用户带到 www.example.com/log_in 。但是，由于某种原因，该用户被带到 example.herokuapp.com/log_in 。在这种情况下，如何将用户重定向到自定义域？

After user signs up, they need to confirm their emails. When they receive an email from my web app, they click the link. I use Devise to confirm user's email by the way. It is supposed to take the user to www.example.com/log_in. However, for some reason, the user is taken to example.herokuapp.com/log_in. How do I redirect the user to custom domain for this edge case?

推荐答案

为此，您要覆盖 default_url_options 在您的环境配置文件中。例如，在您的 config / environments / production.rb 中，您可能需要以下内容：

To do this you want to override the default_url_options in your environment config files. For example, in your config/environments/production.rb you'll probably want the following:

config.action_mailer.default_url_options = {
  host: 'http://www.example.com'
}
config.action_mailer.asset_host = 'http://www.example.com'

无论您设置主机 default_url_options 中的c $ c>将成为通过ActionMailer发送的电子邮件（包括设计确认/密码重置电子邮件）中包含的所有链接的主机。 asset_host 用作您放置在电子邮件中的任何资产（例如图像）的主机，以便可以正确找到它们。

Whatever you set the host of default_url_options to will be the host of any links contained inside emails sent out through ActionMailer (this includes Devise confirmation / password-reset emails). asset_host is used as the host for any assets (eg images) you put inside of your emails, so that they can be found correctly.
