我希望能够在浏览器中预览我的电子邮件.

I would like to be able to preview my emails in the browser.

我正在使用 Rspec 并在 spec/mailers/previews 中有以下预览设置:

I am using Rspec and have the following preview setup in spec/mailers/previews:

# Preview all emails at localhost:3000/rails/mailers/employee_mailer class EmployeeMailerPreview < ActionMailer::Preview def welcome Notifier.welcome_email(Employee.first) end end

当我尝试访问它时，出现以下错误:

When I try to access this I get the following error:

AbstractController::ActionNotFound at /rails/mailers/employee_mailer Mailer preview 'employee_mailer' not found

但是，当我将预览代码放在测试/邮件程序/预览中时它有效.

However, when I put the code for the preview inside of tests/mailers/previews it works.

如何配置我的 Rails 应用以在 spec/mailers/previews 中查找预览?

How can I configure my Rails app to look for the previews inside of spec/mailers/previews?

推荐答案

使用

config.action_mailer.preview_path = "#{Rails.root}/spec/mailers/previews"

在 config/development.rb 中定义预览所在的路径.

in config/development.rb to define the path where previews are located.
