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

First, install haml as a gem in bundler by adding this to your Gemfile:

gem "haml"

Run bundle install, then make sure your views are named with a *.html.haml extension. For example:

`-- app
    `-- views
        |-- layouts
        |   `-- application.html.haml
        `-- users
            |-- edit.html.haml
            |-- index.html.haml
            |-- new.html.haml
            `-- show.html.haml

Answer 2

Add haml to your Gemfile:

gem "haml"

If you want to use the scaffold-functions too, add haml-rails within your development-group:

gem 'haml-rails', :group => :development

Don't forget to run:

$ bundle install

Answer 3

Haml with Rails 3

For Rails 3 all you need to do is add gem "haml", '3.0.25' to your Gemfile. No need to install plugin or run haml --rails ..

Just:

$ cd awesome-rails-3-app.git
$ echo 'gem "haml"' >> Gemfile

And you're done.

Answer 4

First, make sure you have the HAML gem.

gem list --local | grep haml

If haml doesn't show up in the list, then do this:

sudo gem install haml

Then do this from your project directory:

# cd ../
# haml --rails <yourproject>

That should install everything you need, and the HAML views should stop complaining and parse correctly.
