How to make it work?
I have a file index.html.haml
and a index.html.erb. the erb one works, then when i delete the erb, it gives me the template is missing error.
I have rails 2.3.4 and installed the haml gem.
"Template is missing
Missing template profiles/index.erb in view path app/views"
Add config.gem "haml" to your Rails::Initializer.run block in your envrionment.rb file. The old haml --rails yourproject is being phazed out.
You also need a run haml --rails yourproject which will install a initalizer in vender/plugins/haml.

I have installed haml gem in my rails app (v4.2.0 beta4)
but it doesn't seem to compile any output.
I have included gem in my gemfile and ran bundle install and made sure
that I changed my html.erb files to html.haml
This is one of the template and all I see is the heading "New recipe".
%h1 New recipe
= render 'form'
= link_to 'Back', recipes_path
And nothing gets displayed for form partial.
I've come across someone with similar issue and the solution to the issue was making controller inherit
applicationController rather than actionController.
I wonder if this is what I need to do to make it working.
I would have thought installing haml gem would have handled everything needed to get it working.
In your Gemfile, put
gem "haml-rails"
And then of course bundle install
This is the ONLY gem you need to integrate HAML into your Rails app, as it provides the wrappers needed to be able to use ruby logic in your haml views. Simply using haml alone is not sufficient as haml is framework independent.
Since you've added the HAML gem (gem 'haml', '~> 4.0.5'), ran bundle install and restarted your server (Have you restarted your server??) I believe you have installed the Gem correctly.
When you say in your template file you see "New recipe", it makes me think the issue is not with the haml gem but with partial file.
Just to confirm, your partial is saved within the same folder (app/views/recipes/) as:
_form.html.haml
You need to make sure you have the underscore in front of the file name for partials.
I ended up downgrading my project to 4.1.8 and Haml works just fine.
gem 'haml-rails' was not necessary.
gem 'haml' did the job just fine.
I have a Rails 2.3.8 project running on Ruby (Ruby 1.8.7 (2010-06-23 patchlevel 299) [i686-linux]).
I have a folder in app/views called uploads and it has haml file:
_files.html.haml
But when I try to call it using:
<%= render :partial => "/uploads/files"%>
is says:
Missing template /uploads/_users.erb in view path app/views:vendor/plugins/devise-1.0.8/app/views
It appears to be that it tried to locate .erb (_users.erb) where as the file name is _users.html.haml.
How can I fix this?
Do you have the haml gem listed in your gemfile? I believe that's all that needs to be done.
I installed haml 2.2 on a Spree application with
rake gems:install
After placing it in my environment.rb .
Just like I thought, nothing loads anymore. Spree seems to be very exclusive about their source code.
Does anyone know anyway I can delete haml and restore my project?
Go to your config/environment.rb. If you see:
config.gem haml
remove that line.
If you're sure that HAML is not in environment.rb anymore, check that it's not installed as a plugin in vendor/plugins and finally uninstall the gem (sudo gem uninstall haml).
the line
rails new someapp -m haml
doesn't work. It seems to need a path to some where.
Update: haml-rails is in fact installed by gem install haml-rails but the line above wouldn't work.
The really short version
Generate a new rails app based on a simple template that sets up Haml out of the box (and some other nice optional features).
rails new ProjectName -m https://raw.github.com/RailsApps/rails3-application-templates/master/rails3-haml-html5-template.rb
http://decielo.com/articles/377/haml-by-default-in-a-new-rails-3-2-app
Also check this out:
https://github.com/RailsApps/rails-composer
EDIT:
If you want to do this through the "gem" you simply need to run the default command
rails new myapp -m https://raw.github.com/RailsApps/rails-composer/master/composer.rb
This is a safe command as it points to the master branch of the gem and will be a stable URL. Once you have run this command you will be prompted with options. Simply select HAML and SASS when asked by the wizard.
Gem haml-rails allows to generate views in Haml, but not the initial layout.
After running rails new someapp (note: w/o -m haml) and adding line gem "haml-rails" to your Gemfile, you just need to rename application.html.erb to application.html.haml and manually convert its content from ERB to Haml.
After that, all generated views will be in Haml.
app/views/layouts/application.html.haml
!!!
%html
%head
%title "HAML'd"
= stylesheet_link_tag "application"
= javascript_include_tag "application"
= csrf_meta_tags
%body
= yield
Make sure you have the haml-rails gem installed.
Don't forget to add gem 'haml-rails' to your Gemfile.
Trivial, but make sure you restart your rails server after adding the haml gems and run bundle install. This got me the first time around.
Install the gem html2haml and you can instantly change the html content to haml from within vim. Have a look at this - http://www.economyofeffort.com/2014/07/20/convert-html-to-haml-within-vim-buffer/
Rails is suddenly trying to render ERB instead of Haml and I can't figure out why. I've created new rails projects, reinstalled Haml, and reinstalled Rails.
Here's exactly the steps I take when making my application (Rails 2.3.2):
rails> rails test
rails> cd test
rails\test> haml --rails .
rails\test> ruby script\generate model user email:string password:string
rails\test> ruby script\generate controller users index
rails\test> rake db:migrate
Here's what the UsersController looks like:
class UsersController < ApplicationController
def index
#users = User.all
end
end
My routes:
ActionController::Routing::Routes.draw do |map|
map.resources :users
end
I now create views\users\index.html.haml:
%table
%th(style="text-align: left;")
%h1 Users
- for user in #users
%tr
%td= user.email
%td= user.password
Annnd run the server...
I navigate to localhost:3000\users and I get this error message:
Template is missing
Missing template users/index.erb in view path app/views
For some reason Rails is trying to find and render .erb files instead of .haml files.
vendor\plugins\haml\init.rb exists, untouched.
I've reinstalled Haml (Pretty Penny) multiple times and still get the same results.
I've also tried adding config.gem 'haml' to my environment.rb but this also doesn't work.
I can't figure out why suddenly rails will not render haml for me.
Hi it seem like haml is not enabled as Rails plugin ,in order to enable it use the following command .
Go to your application folder from the command prompt type the following
$ cd ..
$ haml --rails <yourproject>
if this doesnot work try installing haml gem with the following code
$ gem install haml
I tried with above example , it did work for me ,i have haml gem installed in my ubuntu system .
Good luck !
NOTE: "haml --rails" was deprecated in HAML 3.1
It's worth noting that the fact that the error message says that it couldn't find index.erb doesn't mean that it didn't look for index.haml too. The erb extension is hard-coded into the error message.
I thought that I had the same problem you describe, but it turned out that my application simply couldn't find my partial at all - it had nothing to do with the file extension.
I had this same problem (see this post) with Rails 2.3.4. Multiple gem uninstall/gem install rails didn't fix the problem. But downgrading to Rails 2.3.2 worked! (I know HAML previously worked in this project with this version of Rails).
sudo gem install -v 2.3.2 rails
Using Rails 3.1, I ran in to the same error and had to restart the web server.
I have this old project in rails 2.3.18, where the gems are managed using bundler, and all I had to do was explicitly use version 3.1.3 It did not work with the latest version (4.0). So in my version I added
gem 'haml', '3.1.3'
did bundle install and restarted my development server :)
Hmmm strange, this might be related.
According to: http://www.ruby-forum.com/topic/101346 you should use resource_url helpers in controllers and resource_path helpers in views. Right?
BUT, if I do use a resource_url helper in a redirect_to call inside my controller, then I get:
Missing template htp://localhost:4000/categories/new.erb in view path app/views
If I use the resource_path helper instead, there aren't any problems at all.
Anyone knows what could be wrong?
Why is the resource_url helper trying to redirect to an .erb file?
This is the error from the server log:
ActionView::MissingTemplate (Missing template http://localhost:4000/categories/new.erb in view path app/views):
haml (2.2.2) lib/haml/helpers/action_view_mods.rb:13:in `render'
app/controllers/categories_controller.rb:15:in `create'
haml (2.2.2) rails/./lib/sass/plugin/rails.rb:19:in `process'
P.S. This is in Rails 2.3.3
maybe your file name is wrong, if you have a whitespace in the end of the index.html.haml_, rails will wrong...
I ran into the same problem and I had to restart my server after installing Haml before my rails app recognized the changes.
I was having this issue with Ruby 1.9x, Rails 2.3.5, and HAML 3.1. I believe part of the issue is that some of the deprecated calls in 1.8 were removed in 1.9.
IMHO, if you want to use HAML in Rails 2, you'd be better off downgrading to Ruby 1.8. (which is what I did to fix my problem). In Rails 2, you MUST have the gem.config "haml" in your config.
Even better, move forward to Rails 3 on Ruby 1.9!
I've had this same problem.
The solution is documented in https://github.com/haml/haml/issues/672
You need to add
config.after_initialize do
require 'haml'
Haml.init_rails(binding)
end
inside your config/environment.rb within the Rails::Initializer.run do |config| configuration block !!
Updated - Not actual anymore:
I name all of my haml file only .haml
To illustrate:
test.haml
# not
test.html.haml
Update 5 years later:
I recommend to name them "file.format.haml", because its much more clear which format is the outcome...
