Environment variables

Conversation

Add gem and file for environment variables?
          1)  None
          2)  Add .env with Foreman

Purpose

Use dotenv gem + .env file + initializers by default

Checklist for changes:

• Add gem 'dotenv-rails' to Gemfile

• Add .env.sample file to the app root with content:

# NOTE: don't forget to:
# 1) add a variable to .env on server
# 2) stop and start puma process (right after you added new variables)

RAILS_ENV=development

• Add script to setup script(copies vars from env sample file to env):

  unless File.exist?(".env")
    cp ".env.sample", ".env"
  end

• Add script to update script(updates env vars from sample file):

def env_sample_vars
  File.read('.env.sample').each_line.inject({}) do |variables, line|
    variable = line.split('=')[0]
    variables.merge({variable => line})
  end
end

def try_to_add_new_env_vars
  env_file = File.read('.env')

  File.open('.env', 'a') do |file|
    env_sample_vars.each do |var_name, var_definition|
      file << var_definition unless env_file.include?(var_name)
    end
  end
end

if File.exist?(".env")
  try_to_add_new_env_vars
else
  cp ".env.sample", ".env"
end
