Rspec 验证失败：电子邮件已被接收

请注意，我不是在创建用户时出错，而是在编辑时出错

我相信电子邮件唯一性检查可以在

设计中完成

Github repo:，但是还没有编辑用户规范rb

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

在您的工厂为您的用户提供

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

应该是

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

您需要双引号来插值
n

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