The following five initializers are included by default in all Rails applications. Backtrace Silencers Nobody likes really long exception backtraces, except maybe Java programmers. Rails has a mechanism for reducing the size of backtraces by eliminating lines that don’t really add anything to your debugging. rb initializer lets you modify the way that backtraces are shortened. I’ve found it useful to remove backtrace entries for noisy libraries, but removing all silencers is usually never needed during normal application development.
A. 0 Superstar. My friendship with David is a big factor in why I’m writing this book today. David’s opinions and public statements shape the Rails world, which means he gets quoted a lot when we discuss the nature of Rails and how to use it effectively. David has told me on a couple of occasions that he hates the “DHH” moniker that people tend to use instead of his long and difficult-to-spell full name. ” When you encounter references to “David” without further qualification, I’m referring to the one-and-only David Heinemeier Hansson.
Autoload_paths in Rails 3 so that it is crystal clear to the develooper that the collection is about stuff that can be autoloaded. Those directories are also added to $:, but in general that is of little interest, because stuff in autoload_paths is usually meant to be autoloaded. Plugin Load Order Normally, Rails loads plugins alphabetically by directory name. If you are unlucky enough to run into a problem with the default order, you can use the following code to adjust ordering. Config # require "action_view/railtie" # require "action_mailer/railtie" # require "active_resource/railtie" 10 Chapter 1: Rails Environments and Configuration # Only load the plugins named here, in the order given (default is alphabetical).
