Migrations & Seeding

What are migrations??

Migrations are a way to make database changes or updates, like creating or dropping tables, as well as updating a table with new columns with constraints via generated scripts. We can build these scripts via the command line using knex command line tool.

To learn more about migrations, check out this article on the different types of database migrations!

var knex;

/**
 * This module extends the knex query builder with selectDistance method,
 * The method adds a virtual column to the current query (qb) with the alias as, in which
 * resides the calculated distance from the geoPoint to the entity.location column.
 * It also accepts some options parameters like the unit (km | mi) and the decimalPrecision of the result.
 * Deps: Postgis
