A resolver that loads files from the filesystem. It allows to set your own resolving pattern. Such pattern can be a glob string supported by some variables.

Examples

Default pattern, loads views the same way as previous versions of rails, eg. when you’re looking for `users/new` it will produce query glob: `users/new{.{en},}{.{html,js},}{.{erb,haml},}` 

  FileSystemResolver.new("/path/to/views", ":prefix/:action{.:locale,}{.:formats,}{.:handlers,}")

This one allows you to keep files with different formats in seperated subdirectories, eg. `users/new.html` will be loaded from `users/html/new.erb` or `users/new.html.erb`, `users/new.js` from `users/js/new.erb` or `users/new.js.erb`, etc. 

  FileSystemResolver.new("/path/to/views", ":prefix/{:formats/,}:action{.:locale,}{.:formats,}{.:handlers,}")

If you don’t specify pattern then the default will be used.

In order to use any of the customized resolvers above in a Rails application, you just need to configure ActionController::Base.view_paths in an initializer, for example: 

  ActionController::Base.view_paths = FileSystemResolver.new(
    Rails.root.join("app/views"),
    ":prefix{/:locale}/:action{.:formats,}{.:handlers,}"
  )

Pattern format and variables

Pattern have to be a valid glob string, and it allows you to use the following variables:

  • :prefix - usualy the controller path
  • :action - name of the action
  • :locale - possible locale versions
  • :formats - possible request formats (for example html, json, xml...)
  • :handlers - possible handlers (for example erb, haml, builder...)
