A demo implementation to support using Point data structure with slick3 on PostGIS and POSTGRESQL

Use PostGis with Slick3

Slick can be a bit mysteric when we have to extend it with new datatypes.

This demo project is looking to provide an example to extend slick with the ability to work with PostGis on POSTGRESQL.

Overview

This is a play 2.6 project. Slick is integrated via the play-slick project. The other relevant dependencies are as below:

• Slick 3.2.0.
• postgis-jdbc 2.2.1
• postgresql driver 42.2.2

The test runs on JDK 1.8, scala 2.12.2. Using postgresql 10 + PostGis 2.4.

Preparation

We need to have a postgresql database with postgis installed.

Install vagrant and use vagrant up to provision a testing postgresql.

The test postgresql runs on host 168.95.56.98. Use the below credential to manage.

• username: postgres
• password: postgres

If you need SSH access, use the below

• username: vagrant
• password: vagrant
• Or simply run vagrant ssh from command line.

Manually prepare the database by creating a new user and database.

-- connect with postgres/postgres
CREATE USER test WITH CREATEDB LOGIN INHERIT PASSWORD 'test';
CREATE DATABASE test OWNER test;

-- connect with postgres/postgres with database test. Ex: \c test in psql
CREATE EXTENSION postgis;

If you wish to use an existing postgresql database, please change conf/application.conf accordingly.

Running

The project has no api or frontend, execute the few test cases from sbt.

sbt test
