You can connect to the Postgres server with explicit ( my

ie username) or implicit ( timonin

ie role in database.yml

).

As I can see yours database.yml

has a username operator, but only for a production environment . Running rake tests without specifying the Rails environment runs them by default for the development environment. This is why you have an error for example FATAL: role "my" does not exist

.

Thus, depending on your needs, you need to add these instructions to all database constraints ( test

and development

):

  username: timonin
  password: <%= ENV['TIMONIN_DATABASE_PASSWORD'] %>

The Rails application will then connect as a user timonin

.

Complete checklist:

  • Create role

Here is the SQL for PostgreSQL:



CREATE ROLE timonin LOGIN PASSWORD 'Pas$_sword'
  NOINHERIT CREATEDB
   VALID UNTIL 'infinity';
COMMENT ON ROLE timonin
  IS 'Timonin database role for Rails app';
  • Uncomment or add statements username: timonin

    and password: <%= ENV['TIMONIN_DATABASE_PASSWORD'] %>

    to database.yml file
  • Run all operations on the variable TIMONIN_DATABASE_PASSWORD

    :

Here's the modified rake command:

rake db:create TIMONIN_DATABASE_PASSWORD='Pas$_sword'

or:

rake db:create TIMONIN_DATABASE_PASSWORD='Pas$_sword' RAILS_ENV=test

for a test environment.

I had the same problem using Ubuntu 14.04 LTS for my Ruby on Rails installation. The problem was that I didn't create a user for my postgres database, so I did the following and it worked.

# 1 logged in as default user
$ sudo su postgres

# 2 enter the postgres
PSQL interactive terminal

Alternatively, you can combine steps # 1 and # 2 like this:
$ sudo su postgres psql



# 3 View the list of roles in the postgres staging terminal
postgres = # \ du

# 4 create a role in postgres database postgres
= # CREATE user with password '';

# 5 Make the user just create superuser
postgres = # change superuser user;

# 6 Exit postgres console
postgres = # \ q
