@user.errors.add(:email, "Not valid")
If you don't want to use any attributes, then in your model
如果您不想使用任何属性，那么在您的模型中
@user.errors[:base] << "This person is invalid because ..."

If you just add errors in a separate method (not in a validation), then by default when you call .valid? or .save those errors will be automatically cleared. So you may want to use validation contexts instead.
如果您只是在单独的方法中添加错误(而不是在验证中)，那么在默认情况下，当您调用.valid时?或者。save这些错误将被自动清除。因此，您可能需要使用验证上下文。
