Announcing online_migrations - a gem that catches unsafe migrations in development and provides helpers to run them easier in production
I’m publishing a new gem today. The name is online_migrations, it’s at https://github.com/fatkodima/online_migrations. For those familiar with strong_migrations, it is a "strong_migrations on steroids".
strong_migrations provides you with text guidance on how to run migrations safer, but my gem have actual code helpers (which the gem suggests to use) you can use to do what you want. For example, it has migration helpers for renaming tables/columns (https://github.com/fatkodima/online_migrations/blob/4eec4c1a21689b291fabf4d315cf465f1d859745/lib/online_migrations/schema_statements.rb#L123-L320), changing column types (https://github.com/fatkodima/online_migrations/blob/master/lib/online_migrations/change_column_type_helpers.rb), adding columns with defaults (https://github.com/fatkodima/online_migrations/blob/4eec4c1a21689b291fabf4d315cf465f1d859745/lib/online_migrations/schema_statements.rb#L343-L424), and more. And ability to run heavy data migrations in background (https://github.com/fatkodima/online_migrations/blob/master/BACKGROUND_MIGRATIONS.md).

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.
