From 2d3a6a0cb8df0360dd588a4d2fb260dd07cc9bcf Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?=C5=81ukasz=20Strza=C5=82kowski?= Date: Tue, 3 Dec 2013 11:17:01 +0100 Subject: Action Pack Variants By default, variants in the templates will be picked up if a variant is set and there's a match. The format will be: app/views/projects/show.html.erb app/views/projects/show.html+tablet.erb app/views/projects/show.html+phone.erb If request.variant = :tablet is set, we'll automatically be rendering the html+tablet template. In the controller, we can also tailer to the variants with this syntax: class ProjectsController < ActionController::Base def show respond_to do |format| format.html do |html| @stars = @project.stars html.tablet { @notifications = @project.notifications } html.phone { @chat_heads = @project.chat_heads } end format.js format.atom end end end The variant itself is nil by default, but can be set in before filters, like so: class ApplicationController < ActionController::Base before_action do if request.user_agent =~ /iPad/ request.variant = :tablet end end end This is modeled loosely on custom mime types, but it's specifically not intended to be used together. If you're going to make a custom mime type, you don't need a variant. Variants are for variations on a single mime types. --- actionview/lib/action_view/testing/resolvers.rb | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'actionview/lib/action_view/testing/resolvers.rb') diff --git a/actionview/lib/action_view/testing/resolvers.rb b/actionview/lib/action_view/testing/resolvers.rb index 7afa2fa613..af53ad3b25 100644 --- a/actionview/lib/action_view/testing/resolvers.rb +++ b/actionview/lib/action_view/testing/resolvers.rb @@ -21,7 +21,7 @@ module ActionView #:nodoc: def query(path, exts, formats) query = "" - EXTENSIONS.each do |ext| + EXTENSIONS.each_key do |ext| query << '(' << exts[ext].map {|e| e && Regexp.escape(".#{e}") }.join('|') << '|)' end query = /^(#{Regexp.escape(path)})#{query}$/ -- cgit v1.2.3
