has_many is a SOLID violation

TL;DR has_many is an anti-pattern which leads straight to monolithic applications.

First - what defines a monolithic application? It is one that cannot be split apart because everything depends on everything else. No part can be extracted to an external library - the library would have to be the size of our entire app. Let this be our working definition of a monolith. Ignore, for the moment, whether it's deployed on more than one machine, but ask could it be separated if you desired.

One major culprit of not being able to split an application up is a dependency cycle.

-- Firstly, remove PRIMARY KEY attribute of former PRIMARY KEY
ALTER TABLE <table_name> DROP CONSTRAINT <table_name>_pkey;

-- Then change column name of  your PRIMARY KEY and PRIMARY KEY candidates properly.
ALTER TABLE <table_name> RENAME COLUMN <primary_key_candidate> TO id;

Locate the section for your github remote in the .git/config file. It looks like this:

[remote "origin"]
	fetch = +refs/heads/*:refs/remotes/origin/*
	url = git@github.com:joyent/node.git

Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:
