Render ERB JS templates with Underscore.js and Sprockets and Tilt in Rails 3.1

templates.js.coffee.erb

# creates a global JST object containing all the templates
# 1. install Tilt in your Gemspec
# 2. Paste this in a file at app/assets/javascripts/templates.js.coffee.erb
# 3. `require` the templates file from your main js include file.
# 4. Put your templates at app/views/whatever/my_template.html.jst

window.JST =
<% Dir[Rails.root.join('app/views/**/*.jst')].each do |path| %>
  <%= path.match(%r{/([^/]+)\.html\.jst$})[1] %>: _.template(<%= File.read(path).inspect.gsub(/\r?\n/, '') %>)
<% end %>

this isn't reloading in development mode. any solution to that?

I think Rails only renders the CoffeeScript to JS whenever the file is changed. That's probably why it won't reload. Not sure how to get around that at the moment. Maybe try touching the templates file as a workaround?

Yes, we're doing that but it's proving painful to say the least :)

Cheers

Looks like a good fit for guard
