我一直在尝试为忘记密码的用户添加密码重置。用户点击忘记密码？在注册页面上。然后用户键入他们的电子邮件并单击重置密码，这会创建一个令牌并发送一封电子邮件，其中包含重置密码的链接。在大多数情况下，它仅在电子邮件框为空白或正好有 6 个随机字母/数字时有效，但当用户输入他的电子邮件并单击密码重置时它不起作用，它会显示错误消息：
**Validation failed: Password can't be blank
Password cant be blank, password is too short(6 min)**
通过更改user.rb 验证：password，presence：true，length：{ minimum: 6 } validates ：password_confirmation，presence：true
我得到了不同的错误，无论如何要从这个重置密码表单中排除这个验证
app/models/user.rb:30:in `send_password_reset'
app/controllers/password_resets_controller.rb:7:in `create'
在视频 275 How I Test 中遇到此错误。11:20
失败/错误：click_button "Reset Password" ActiveRecord::RecordInvalid: 验证失败：密码不能为空，密码太短（最少为 6 个字符），密码确认不能为空
