7 Patterns to Refactor Rails Models 7 years later

You may have read the following excellent blogpost by Brian Helmkamp of CodeClimate. It nicely describes 7 types of objects that can be extracted from models and controllers in a Rails-app.

Here are my thoughts on it, reading it as an experienced rails developer, 7 years later 😅 👴

Solution of psql: FATAL: Peer authentication failed for user “postgres” (or any user)

psql: FATAL: Peer authentication failed for user “postgres” (or any user)

The connection failed because by default psql connects over UNIX sockets using peer authentication, that requires the current UNIX user to have the same user name as psql. So you will have to create the UNIX user postgres and then login as postgres or use sudo -u postgres psql database-name for accessing the database (and psql should not ask for a password).

If you cannot or do not want to create the UNIX user, like if you just want to connect to your database for ad hoc queries, forcing a socket connection using psql --host=localhost --dbname=database-name --username=postgres (as pointed out by @meyerson answer) will solve your immediate problem.

But if you intend to force password authentication over Unix sockets instead of the peer method, try changing the following pg_hba.conf* line:
