# Read In Environment-Specific Config Values
|
|
|
|
The [`config_for`](https://apidock.com/rails/Rails/Application/config_for)
|
|
method allows you to read in a YAML file for the current environment in your
|
|
config files. These YAML files need to be located in the `config` directory.
|
|
|
|
For instance, let's say you have `config/extra_settings.yml`:
|
|
|
|
```yml
|
|
development:
|
|
support_email: support+dev@test.com
|
|
|
|
production:
|
|
support_email: support@test.com
|
|
```
|
|
|
|
You can read that file in as part of your `application.rb` config setup:
|
|
|
|
```ruby
|
|
# config/application.rb
|
|
module MyApp
|
|
class Application < Rails::Application
|
|
extra_settings = config_for(:extra_settings)
|
|
set_support_email(extra_settings.fetch(:support_email))
|
|
end
|
|
end
|
|
```
|
|
|
|
In `development` this call to `config_for` would return a hash of the values
|
|
under `development`. Likewise in `production`.
