我已经为我的Rails应用程序（3.0.1）安装了Devise，它主要工作。我只是似乎无法自定义邮件程序视图。
app/controllers/users/中，如此app/controllers/users/sessions_controller.rb app/views/users/一样app/views/users/registrations/new.html.haml devise_for :users, :controllers => {
:sessions => "users/sessions",
:registrations => "users/registrations",
:passwords => "users/passwords",
:confirmations => "users/confirmations",
:unlocks => "users/unlocks"
} do
get "/login" => "devise/sessions#new"
get "/logout" => "devise/sessions#destroy"
end
至少在上面的一切都有效。但是，在发送邮件时， Devise似乎使用的模板不是我在app/views/users/mailer/ 编辑的模板。设计似乎仍然是默认的（好像我从未编辑过文件）。我猜测Devise仍然使用gem中的文件。
如果有帮助，这是黄瓜错误：
Feature: Manage accounts
In order to manage accounts
users
should be able to signup
# By default, www.example.com is the host when testing.
# This is a problem because when our site searches for the domain example.com, it cant find any.
# Therefore we must either set our testing domain to one of our choosing (and mention that in the routes), or create a domain example.com
# I prefer the first option.
Scenario: Signing up and resetting the password # features/manage_accounts.feature:10
Given I am on the login page # features/step_definitions/web_steps.rb:19
When I follow "Sign up" # features/step_definitions/web_steps.rb:33

另外，如果它有帮助，这里是我已经覆盖的控制器：
| | |~users/
| | | |-confirmations_controller.rb
| | | |-passwords_controller.rb
| | | |-registrations_controller.rb
| | | |-sessions_controller.rb
| | | `-unlocks_controller.rb
如何解决此问题？
谢谢！

我认为您需要自己管理Devise视图。在控制台中尝试以下操作：
rails generate devise:views
这将生成Devise使用的所有视图（包括邮件程序模板），您现在可以自定义它们。
您正在寻找的邮件应该是'app / views / devise / mailer'
如果您想生成范围内的视图，或者只想生成其中一部分视图。根据{{3}}的文档：
您还可以使用生成器生成范围视图：
rails generate devise:views users
如果您只想生成几组视图，例如可注册和可确认模块的视图，您可以使用-v标志将模块列表传递给生成器。
rails generate devise:views -v registrations confirmations
答案 1 :(得分：30)
按资源名称
生成视图rails generate devise:views users
通过recoverable
rails generate devise:views users -v passwords
仅生成指定邮件视图
rails generate devise:views users -v mailer
了解更多详情generate views
答案 2 :(得分：22)
你应该编辑你的config / initializers / devise.rb：
config.scoped_views = true
（默认情况下注释）
通过这样做，您可以为不同的模型而不是全局设计自定义视图。答案 3 :(得分：1)
如果您有兴趣不使用Devise的ActionMailer默认用法，而是想通过SendGrid，Mailgun或Postmark之类的服务使用API发送自定义电子邮件，则可以需要创建一个自定义Mailer的子类，该子类继承Devise::Mailer并覆盖其“通知”方法。

试试这个：
rails generate devise:views
答案 5 :(得分：0)
如果您只想生成电子邮件视图，则可以使用：rails g devise:views [SCOPE] -v mailer。您的情况下的[SCOPE]是users。
注意：我正在使用Devise 4.7.3。
