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 or index.html.haml for a view, I just receive errors.
I am using NetBeans as my IDE.
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.
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
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
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
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>
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.
This may be an old question but I think the answer is using haml-rails at https://github.com/indirect/haml-rails
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.
