Example: golang gorm postgres uuid relation

I was trying forever to get autoloading relationships working with postgres 9.4 and gorm and primary keys of type uuid.

Many tutorials and examples, even those on the official docs were just not workiong or missing important details.

The program in this gist creates the table structure and inserts a nested record. A parent and a child object is created by simply creating the child, which holds the relation to a parent. The child element then is queried by ID. The returned object holds the nested parent object.

Used package versions:

package main

import (
	"context"
	"crypto/tls"
	"fmt"
	"log"
	"net/http"
	"net/url"
	"time"

Build Aurora 0.7.1-SNAPSHOT on CentOS 6.5

I created a CentOS 6.5 Droplet on Digital Ocean with 8GB RAM (you'll need at least 4 for the Java portion of the build), feel free to use any other CentOS 6.5 environment that you can have root on.

Prepare the Environment

First, Mesos 0.21.0+ requires subversion 1.8+ devel package which is not available by default by yum. Add a repo that has subversion-devel 1.8 available, i.e:

Add new repo /etc/yum.repos.d/wandisco-svn.repo, with:
