Question

所以我正在开发一个rails引擎并生成一个邮件，将我的观点放在

中

app/
  views/ 
    my_engine/ 
      user_mailer/
        account_activation.html.erb
        account_activation.text.erb

配置虚拟应用以显示我添加的预览

测试/虚设/配置/环境/ development.rb

config.action_mailer.preview_path = MSearcher::Engine.root.join('test/mailers')

测试/邮寄者/预览/ my_engine / user_mailer_preview.rb

module MyEngine
    class UserMailerPreview < ActionMailer::Preview
        def account_activation
            User.first
            UserMailer.account_activation(user)
        end
    end
end

现在，如果我创建我的邮件

/应用/邮寄者/ my_engine / user_mailer文件

module MyEngine
    class UserMailer < Application Mailer
        def account_activation(user)
            mail to: user.email, subject: "Account Activation"
        end
    end
end

有了这个，我可以导航到 localhost：3000 / rails / mailers / my_engine / users_mailer / account_activation

我收到错误

Template is missing
Missing template layouts/mailer with {:locale=>[:en], :formats=>[:html], :variants=>[], :handlers=>[:raw, :erb, :html, :builder, :ruby, :coffee]}. 
Searched in: * 
    "/home/me/workspace/rails/my_engine/test/dummy/app/views" * 
    "/home/me/workspace/rails/my_engine/app/views"

所以默认行为是在应该存在的文件夹上方查找我的模板。如何配置正确的行为？

我最终做的是告诉它哪里可以找到布局

当我生成我的邮件时，它在

中创建了一个默认布局

app/
  views/ 
    layouts
      my_engine/
        mailer.html.erb
        mailer.text.erb
    my_engine/ 
      user_mailer/
        account_activation.html.erb
        account_activation.text.erb

app / mailers / my_engine / application_mailer.rb

中的默认模板

module MyEngine
  class ApplicationMailer < ActionMailer::Base
    default from: 'from@example.com'
    layout 'mailer'
  end
end

这个布局确实应该是'my_engine / mailer'我不知道为什么Rails不会自动执行此操作，但这解决了我的问题。

rails engine mailer缺少模板
