![]() ![]() Zeitwerk uses absolute paths internally, and applications running in :zeitwerk mode do not need require_dependency, so models, controllers, jobs, etc. This flag is true by default, but it is recommended to be set to false in :zeitwerk mode early, in config/application.rb. Says whether autoload paths have to be added to $LOAD_PATH. 3.2.5 config.add_autoload_paths_to_load_path Since Rails 6, it is not recommended to adjust this. 3.2.4 toload_pathsĪccepts an array of paths from which Rails will autoload constants. All elements of this array must also be in autoload_paths. Otherwise, all autoloading happens only once. Relevant if config.cache_classes is false, which is the default in the development environment. 3.2.3 toload_once_pathsĪccepts an array of paths from which Rails will autoload constants that won't be wiped per request. Shorter version of config.action_controller.asset_host. Useful when CDNs are used for hosting assets, or when you want to work around the concurrency constraints built-in in browsers using different domain aliases. delete 'div' end Copy 3.2.2 config.asset_host ![]() Useful for configuring values set up by other initializers:Ĭonfig. Note that this block will be run for rake tasks. That includes the initialization of the framework itself, engines, and all the application's initializers in config/initializers. Takes a block which will be run after Rails has finished initializing the application. The following configuration methods are to be called on a Rails::Railtie object, such as a subclass of Rails::Engine or Rails::Application. config.action_controller.wrap_parameters_by_default: true.config.action_controller.raise_on_open_redirects: true.3.1.1 Default Values for Target Version 7.0 In cases of conflicting values, newer versions take precedence over older versions. For example, config.load_defaults 6.1 will load defaults for all versions up to and including version 6.1.īelow are the default values associated with each target version. 3.1 Versioned Default ValuesĬonfig.load_defaults loads default configuration values for a target version and all versions prior. This will break because autoloading during initialization cannot be safely repeated when the app reloads. If you need to apply configuration directly to a class, use a lazy load hook in an initializer to avoid autoloading the class before initialization has completed. ![]()
