Introduction

This document outlines how to model a common organization-based permission system in Hasura. Let's assume that you have some table structure like the following:

Table Name	Columns	Foreign Keys
User	id, name, email
Organization User	id, user_id, organization_id	user_id -> user.id, organization_id -> organization.id
Organization	id, name

CREATE TABLE accounts(
	id serial PRIMARY KEY,
	name VARCHAR(256) NOT NULL,
	parent_id INTEGER REFERENCES section,
    	parent_path LTREE
);

CREATE INDEX account_parent_path_idx ON accounts USING GIST (parent_path);
CREATE INDEX account_parent_id_idx ON accounts (parent_id);

You have to do 2 things in order to allow your container to access your host's postgresql database

1. Make your postgresql listen to an external ip address
2. Let this client ip (your docker container) access your postgresql database with a given user

Obs: By "Host" here I mean "the server where docker is running on".

Make your postgresql listen to an external ip address

Find your postgresql.conf (in case you don't know where it is)

$ sudo find / -type f -name postgresql.conf
