How do I get Haml to work with Rails?

Question

I am trying to get Haml to work with my Ruby on Rails project. I am new to Ruby on Rails and I really like it. However, when I attempt to add an aplication.html.haml

Answer 1

Before trying to use haml in your rails application, you can verify that the command line executable is installed correctly:

$ haml
%p 
  %span Hello World!

Then press CTRL-D and you should see:

<p>
  <span>Hello World!</span>
</p>

Answer 2

if for some reason you installed haml, but you haml doesn't start. try

sudo ln haml /usr/bin/

in the bin directory of your haml gem

for some reason this didn't happen automatically on my ubuntu 9.04 Jaunty.

Answer 3

make sure to add haml gem into your Gemfile

Answer 4

This may be an old question but I think the answer is using haml-rails at https://github.com/indirect/haml-rails

Answer 5

The answers above are spot-on. You just need to put gem 'haml' in your Gemfile.

One other tip that was not mentioned: to have rails generators use haml instead of erb, add the following to config/application.rb:

config.generators do |g|
  g.template_engine :haml

  # you can also specify a different test framework or ORM here
  # g.test_framework  :rspec
  # g.orm             :mongoid
end

If you are using Pow you will need to restart it also. Ideally you are using powder (gem install powder), because then you can just run this at the terminal

$ powder restart
