What is this?

This is a test project I created for a proof of concept.

The basic issue is that we use an EAV database design. However, we have several entities that need to use the attribute-value structure. I tried to solve it using single table inheritance. It seems to be quite nice right now.

You can load testdata using: doctrine:fixtures:load

JSONB

I added the JsonbArrayType in AppBundle\Types. That basically inherits from JsonArrayType and changes json to jsonb.

The bad part is that I need to use a workaround for using the contains function. But that's ok.

Setup Postgres

We will use the jsonb Postgre type to save the Values to. Be aware that you need to install at least Postgre 9.4. The jsonb will not work with <9.4

To setup Postgre we have to execute the following:

apt-get install postgresql postgresql-client
apt-get install php5-pgsql
adduser mypguser
su - postgres
psql
CREATE USER mypguser WITH PASSWORD 'mypguserpass';
CREATE DATABASE mypgdatabase;
GRANT ALL PRIVILEGES ON DATABASE mypgdatabase to mypguser;
