implementing timestamp precision when saving records in Rails 7.1 with PostgreSQL
I'm building a feature where I am working with a question with timestamp precision when saving records in my Rails 7.1 application using PostgreSQL. I have a model `Event` with a `start_time` attribute defined as `t.datetime :start_time, precision: 6` in my migration. However, when I save an event, the timestamp gets rounded to the nearest second, losing the microsecond precision I expect. Here's a quick look at my migration: ```ruby class CreateEvents < ActiveRecord::Migration[7.1] def change create_table :events do |t| t.datetime :start_time, precision: 6 t.timestamps end end end ``` When I try to save an event with a timestamp like `2023-10-01 12:30:15.123456`, it gets saved as `2023-10-01 12:30:15` instead. I verified that my PostgreSQL database is set to allow microsecond precision by checking the column type in the schema: ```sql SELECT column_name, data_type, datetime_precision FROM information_schema.columns WHERE table_name = 'events'; ``` This returns `start_time` with a `datetime` type and a precision of 6. I've also tried adjusting the time zone settings in my `application.rb` file, setting `config.active_record.default_timezone = :utc`, but that didn’t help either. I’m unsure if this is a misconfiguration in my Rails app or a limitation of PostgreSQL. Has anyone experienced this scenario before? Any insights would be appreciated. I recently upgraded to Ruby LTS. Any feedback is welcome!
