Reference variables between services

Just wondering... is it possible to reference a variable on my postgresql service (DB_HOST, DB_PORT...) on my other web service variables?
like: ${{ DB_HOST }}

other variables arent

Well, it didnt.

did u make the databases after you already deployed ur other web service

had to configure it myself, it didnt detect my .env file on my project either

no

atleast this was simple to do, just copy/pasted it into the raw editor

but the question remains, can I reference my service host variable on my web service variables?

what db is this

postgres

railway doesn't have these env vars

where did u get this Postgres from

did u deploy it urself

no, it was just an example

if i were to reference it in another service

then this answers your question

Ok, thanks.
For anyone finding this thread :
You can use database variables on other services, but not other vars.
