It contains: 6 | 7 | * handlebars.js 8 | * A HandlebarsView superclass 9 | * a rails helper module for rendering all your handlebars templates into your rails view 10 | 11 | Usage 12 | ===== 13 | 14 | This gem is designed to integrate with the asset pipeline of rails 3.1+. Somewhere in your 15 | coffeescript or javascript code you'll need to require it: 16 | 17 | #= require handlebars_view 18 | 19 | This will bring in handlebars and the view superclass. To use it, write a view like so: 20 | 21 | class FooView extends HandlebarsView 22 | 23 | name: "foo_view" 24 | 25 | This will cause the view to look for a template in an element with id "foo_view_template" and use 26 | handlebars to render this view, passing in the attributes of this view's model as the template 27 | context. You can change this by overriding the templateContext function in your view. 28 | 29 | RenderTemplatesHelper 30 | ====================== 31 | 32 | We've found it best practice to keep our handlebars templates in separate files so our rails 33 | views don't get all noisy. This all let's use the same HandleBars view on more than one rails 34 | view and in our jasmine specs. This gem also includes a rails helper module RenderTemplatesHelper. 35 | Best to just look at the code to see what it does for now, it's super simple. -------------------------------------------------------------------------------- /Rakefile: -------------------------------------------------------------------------------- 1 | # encoding: utf-8 2 | 3 | require 'rubygems' 4 | require 'bundler' 5 | begin 6 | Bundler.setup(:default, :development) 7 | rescue Bundler::BundlerError => e 8 | $stderr.puts e.message 9 | $stderr.puts "Run `bundle install` to install missing gems" 10 | exit e.status_code 11 | end 12 | require 'rake' 13 | 14 | require 'jeweler' 15 | Jeweler::Tasks.new do |gem| 16 | # gem is a Gem::Specification... see http://docs.rubygems.org/read/chapter/20 for more options 17 | gem.name = "backbone-handlebars" 18 | gem.homepage = "http://github.com/superchris/backbone-handlebars" 19 | gem.license = "MIT" 20 | gem.summary = %Q{Backbone views with handlebars templates} 21 | gem.description = %Q{That's all folks} 22 | gem.email = "superchrisnelson@gmail.com" 23 | gem.authors = ["Chris Nelson"] 24 | gem.files.include "vendor/assets/**/*" 25 | gem.files.include "lib/**/*" 26 | # dependencies defined in Gemfile 27 | end 28 | Jeweler::RubygemsDotOrgTasks.new 29 | 30 | require 'rake/testtask' 31 | Rake::TestTask.new(:test) do |test| 32 | test.libs << 'lib' << 'test' 33 | test.pattern = 'test/**/test_*.rb' 34 | test.verbose = true 35 | end 36 | 37 | require 'rcov/rcovtask' 38 | Rcov::RcovTask.new do |test| 39 | test.libs << 'test' 40 | test.pattern = 'test/**/test_*.rb' 41 | test.verbose = true 42 | test.rcov_opts << '--exclude "gems/*"' 43 | end 44 | 45 | task :default => :test 46 | 47 | require 'rake/rdoctask' 48 | Rake::RDocTask.new do |rdoc| 49 | version = File.exist?('VERSION') ?
