Osm Admin: Adding Explicit Properties. Data Conversions

2022 April Osm Admin

2 years ago ∙ 4 minutes read

This time, I tackled adding an explicit property to an existing table, and then making it non-nullable.

It raised the need for data conversions - additional handling of the existing data - or otherwise, the database engine fails, or the data becomes invalid.

And it made me split migrations in two parts - the one that runs before the data conversion, and the other one that runs afterwards.

Osm Admin: Schema Migrations In Development Vs Production

Schema migrations are going to be generated and executed automatically under gulp watch. It will result in lots of tiny migrations: add a column, change its type, make it not nullable, and so on.

It's convenient during development, but it might be not optimal to reapply in production. Indeed, it's better to convert a large table to new structure all at once rather than running a conversion for each of the tiny migration.

This observation contradicts the previously stated migration workflow, so let's update it.

osm.software: Deploying Updates

2021 September osm.software Website

After pushing changes to GitHub, osm.software website is updated without any additional manual action. On push, GitHub executes the deployment script on the production server. Most changes are done to content only, and in this case, the deployment script only updates the search index. Otherwise, with the website being on maintenance, it additionally updates Composer and Node dependencies, builds JS and CSS assets, and runs the database migrations.
