Database Views & Rails Active Record: defining new Model classes out of views
To model our Deliverable class, we will need a view. We will use the popular scenic gem, which provides some useful generators for creating views with their respective migrations, and utilities to handle views versioning.

Most performant way to build an analytics dashboard from a relational database backend that only stores numeric values, where the data the end-user sees is "categorized" into numeric brackets (e.g. 60-79 = Med, 80-100 = High, etc)
If the data doesn't need to be close to real-time, and if your DB can handle a bit of load, I'd use a "batch" approach. To do this, I'd create a materialized view in your relational DB that you'd then refresh periodically. The easiest way to do this is with the `scenic` gem. Once you've done this, you can simply create a new model and set the `table_name` to the name of the materialized view, and then treat it as a regular model.

Logidze 1.0, postgres-specific alternative to eg paper_trail for recording ActiveRecord change history
TIL about fx gem for storing triggers in schema.rb. That makes me so happy because scenic gem for creating database views is one of my favorites. Postgres is very powerful and it's great to see tools for exposing that through Rails.
What are some alternatives?
