Rails: FATAL - Peer authentication failed for user (PG::Error)

Question

I am running my development on Ubuntu 11.10, and RubyMine

Here is my development settings for the database.yml: which RubyMine created for me

develop         


        

Answer 1

You can go to your /var/lib/pgsql/data/pg_hba.conf file and add trust in place of Ident It worked for me.

local   all all trust
host    all 127.0.0.1/32    trust

For further details refer to this issue Ident authentication failed for user

Answer 2

I also faced this same issue while working in my development environment, the problem was that I left host: localhost commented out in the config/database.yml file.

So my application could not connect to the PostgreSQL database, simply uncommenting it solved the issue.

development:
  <<: *default
  database: database_name

  username: database_username 

  password: database_password

  host: localhost

That's all.

I hope this helps
