# class ActionView::FileSystemResolver

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...)
