使用rails将值插入时间戳字段mysql

Question

我将表迁移到了2个额外的列，其中：timestamp字段如下所示

class AddingStartAndEndTimeForQuestions < ActiveRecord::Migration
  def change
    add_column :questions, :eventMode, :boolean, default: false
    add_column :questions, :eventModeStartTime, :timestamp
    add_column :questions, :eventModeEndTime, :timestamp
  end
end

我无法从rails控制台手动在此字段中插入时间戳。

我试过

q.eventModeStartTime = Time.now
q.eventModeStartTime = Time.zone.now
q.eventModeStartTime = DateTime.now
q.eventModeStartTime = Time.now.to_s(:db)

Mysql错误：

Mysql2::Error: Incorrect datetime value: '2015-09-23 22:46:28.109.109000' for column 'eventModeStartTime'

如何手动插入？我在这里做错了吗？

INSERT INTO `db_name`.`table` 
  (`id`, `field`, `created_at`, `updated_at`) 
VALUES 
  ('1', 'field_value', '2020-07-05 16:42:17', '2020-07-05 16:42:18');
