.fetch(key) ⇒ Object

2 levels of configuration:

config/app_config.yml “‘

app:
  name:
    detail:
db:
  readonly: true

“‘

Environment variables. Variable name will be downcase and replace ‘__` by `.` “`

APP__NAME__DETAIL=octopus
APP__NAME2=octopus2

“‘ Value in environment variable will overwrite value in `config/app_config.yml` BUT key will be ignore if doesn’t exists in ‘config/app_config.yml` So in case above, “`

TpCommon::AppConfig::Environment.fetch(:'app.name.detail') # => "octopus"
TpCommon::AppConfig::Environment.fetch(:'app.name2') # => nil

“‘ We could mixed both to use, but we recommend:

use `config/app_config.yml` which committed to repo to know
  how many, what are config we use in app
  with default value (optional)
use environment variables for differences config between stages (producion, staging, pre-production, ...)
