验证失败：电子邮件已被占用

Question

请注意，我遇到此错误不是在创建用户时，而是在编辑时。

我相信电子邮件唯一性的检查可以在devise 内完成。

Github 仓库：https://github.com/tenzan/shop，但 editing_users_spec.rb 还没有。

$ bundle exec rspec spec/features/admin/editing_users_spec.rb
FF

在您的工厂中为您拥有的用户...

sequence(:email) { |n| 'test#{n}@example.com' }

应该是……

sequence(:email) { |n| "test#{n}@example.com" }

n的插值需要双引号
