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.

Go has excellent build tools that mitigate the need for using make. For example, go install won't update the target unless it's older than the source files.

However, a Makefile can be convenient for wrapping Go commands with specific build targets that simplify usage on the command line. Since most of the targets are "phony", it's up to you to weigh the pros and cons of having a dependency on make versus using a shell script. For the simplicity of being able to specify targets that can be chained and can take advantage of make's chained targets,
