问题描述
我无法解决旧版 MysqL 数据库的问题。我相信罪魁祸首是其中一个字段的类型设置错误（它包含以毫秒为单位的时间，适配器不希望具有 DateTime 类型），不幸的是我无法更改它。 会发生什么（使用 Ruby on Jets）：
2.5.8 :001 > User.all.each {|u| puts u.inspect};mil
Traceback (most recent call last):

ArgumentError (hour out of range)
我试图修补这个，但我认为我修补的不是正确的东西，看起来要改变的是适配器（哎哟...）。
我见过其他更改过的 ActiveSupport 但它对我不起作用，而且基本上我无法在 ActiveRecord 崩溃的情况下遍历我的记录。我什至无法解决问题，我不知道为什么，但 rescue ArgumentError 不会被该异常触发。
有没有人遇到过这个问题并设法禁用记录的 AR 解析？获得使 AR 和 / 1000 崩溃的值就足够了，但我显然找不到办法做到这一点。
型号：
class User < ApplicationRecord
self.table_name = :user
self.primary_key = :user_id
alias_attribute :first_name,'user_firstname'
alias_attribute :last_name,'user_lastname'
alias_attribute :email,'user_email'
alias_attribute :phone,'user_contact_number'
alias_attribute :job_title,'user_job_title'
alias_attribute :contact_status,'user_contact_status'
alias_attribute :created_at,'user_created'
# has_one :settings,class_name: 'UserSettings'
# has_many :cases,foreign_key: :created_by_user_id
# has_many :subscriptions,-> { order('id DESC') }
# has_many :orders,foreign_key: :user_id
end
