Compare with:

environment(data = nil, options = {})

Adds configuration code to a Rails runtime environment.

By default, adds code inside the Application class in config/application.rb so that it applies to all environments.

environment %(config.asset_host = "cdn.provider.com")

Results in:

# config/application.rb
class Application < Rails::Application
  config.asset_host = "cdn.provider.com"
  # ...
end

If the :env option is specified, the code will be added to the corresponding file in config/environments instead.

environment %(config.asset_host = "localhost:3000"), env: "development"

Results in:

# config/environments/development.rb
Rails.application.configure do
  config.asset_host = "localhost:3000"
  # ...
end

:env can also be an array. In which case, the code is added to each corresponding file in config/environments.

The code can also be specified as the return value of the block:

environment do
  %(config.asset_host = "cdn.provider.com")
end

environment(nil, env: "development") do
  %(config.asset_host = "localhost:3000")
end

Parameters

data opt = nil
options opt = {}
