@amplication/plugin-db-postgres

Use a PostgreSQL database in the service generated by Amplication.

Note: this plugin is used by the code generation engine by default when no other DB plugin is installed.

Purpose

This plugin adds the required code to use PostgreSQL database in the service generated by Amplication. It updates the following parts:

• Updates the datasource on the schema.prisma file:
  • For versions older than 1.3.3 the datesource name is based on the database type
    • PostgreSQL - the datasource name is postgresql
  • From version 1.3.3 the datasource name is db, no matter what is the database type
• From version 1.3.3 as the datasouce name is db, all the custom attributes that use the @{datasource.name}.{nameOfTheAttribute} are replaced with @db.{nameOfTheAttribute}
• Adds the requires services and variables to docker-compose.yml
• Add the db service to the docker-compose.dev.yml
• Add the requires environment variables to .env

Configuration

The plugin uses the parameters configured on the database tab on the service settings page

Usage

This plugin integrates with the all default tasks and scripts used by the generated service:
