New TIL post on ActiveRecord Custom Types

In developing bracket-lab, I needed a 1-indexed bit field of 63 bits, stored as an unsigned 63-bit value in an int64 column.

ActiveRecord’s custom types made this clean.

#ruby #rails #activerecord

It happens you need some field in the database to not contain an empty string, but to be NULL. For example, a unique index has been added to this field, meaning there can only be one record with an empty string. However, if the field has a NULL value, it is unique and there can be multiple such records.

At Kaigi on Rails 2025, Rails Committer Yasuo Honda walked through:

• Protocol 3.2 & extended cancel keys
• Why pg ≥ 1.6 matters
• UNLOGGED partition removal
• pg_stat_statements improvements
• Virtual generated columns (now default in PG18)
• Rails 8.1 adapter support

This is a great example of ecosystem coordination:
PostgreSQL core → pg gem → Rails adapter → production apps.

e.g. Yesterday I Learned about #ActiveRecord's overloading of the #Ruby "shovel" ("<<") operator, and a couple of weeks ago I started a foray into #Rails YAML serialisation, which seems to have changed quite a bit between versions, leading to inconsistently-formatted data in the database, and the exciting prospect of writing a data migration that runs raw SQL queries 😵

ActiveRecord: опасная магия

В Ruby‑разработке ActiveRecord давно стал стандартом: он интуитивно понятен, встроен в Rails и позволяет быстро проводить CRUD‑операции. По мере роста проекта его «удобство» нередко начинает оборачиваться скрытыми проблемами.

How fast can an ActiveRecord SQL query run?, by Fritz Meissner

I know #SQLite3 supports #SQL comments in newer versions with the right flags, but `rails g` for #ActiveRecord ďoesn’t seem to support them except in #PostgreSQL or #MySQL / #MariaDB. Is there a workaround?
