Error to connect to database

[brunofrank]

Hello everyone,

I came across with a very weird behavior, when I setup the database in database.yml it can't connect, it just shows the error could not obtain a database connection within 5.000 seconds (waited 5.000 seconds) (ActiveRecord::ConnectionTimeoutError)

When I type ActiveRecord::Base.configurations on the console, it returns an empty hash ({}) it's like it could not load the database.yml file.

I work around this declaring a DATABASE_URL environment variable

I tried to create a brand new project with stealth new <NAME> and run the command with the default configurations and sqlite adapter, but I had the same problem.

Versions:

Ruby 2.4.7 Stealth 1.1.6 and I tried 1.1.5 too ActiveRecord 5.2.4.3

database.yml

default: &default
  adapter: postgresql
  host: <%= ENV['POSTGRES_HOST'] %>
  username: <%= ENV['POSTGRES_USER'] %>
  password: <%= ENV['POSTGRES_PASSWORD'] %>
  database: <%= ENV['POSTGRES_DB'] || 'zion_bot_dev' %>
  port: <%= ENV.fetch('POSTGRES_PORT', 5432) %>
  encoding: unicode
  pool: <%= ENV.fetch("STEALTH_MAX_THREADS", 5).to_i %>

development:
  <<: *default

staging:
  <<: *default
  pool: 5

test:
  <<: *default
  database: zion_bot_test

production:
  <<: *default
  pool: 10

Looks like some ERB parsing is missing in https://github.com/hellostealth/stealth/blob/af5c4705157c979c5ea3df9b91de9abe5428877c/lib/stealth/base.rb#L126-L132

It's loading the config file as is and considers the <%= ENV.fetch... as text instead of parsing it to the appropriate value...

I suppose something like this would do:

 if ENV['DATABASE_URL'].present? 
   ActiveRecord::Base.establish_connection(ENV['DATABASE_URL']) 
 else 
   database_config = File.read(File.join(Stealth.root, 'config', 'database.yml'))
   ActiveRecord::Base.establish_connection( 
     YAML.load(ERB.new(database_config).result)[Stealth.env]
   ) 
 end
