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 am using Rails 4.1.1 and Ruby 2.0.0. When I run rails new test_app, the generated file test_app/config/environments/development.rb always contains the first line:
Rails.application.configure do
The above line causes an undefined local variable error. It should be:
TestApp::Application.configure do
Is there a way to configure rails so that it always generates the correct name?
Using Ruby 2.0.0 and Rails 4.1.1, I just created a new Rails app using the command rails new test_app_rails_4-1-1. The top line of the development.rb file is Rails.application.configure do, which is the correct syntax.
I just looked at a the development.rb file in a Rails 4.0.1 app. The first line in that file is HeyLookARailsApp::Application.configure do. So it seems like the syntax in Rails 4.1.1 is different that Rails 4.0.1.
I have a Rails 1.2.6 application and I would like to be able to create a folder in app/ and have its contents loaded.
This is the behaviour of Rails 3. How can I achieve the same thing in Rails 1.2.6?
in config/environment.rb
config.load_paths += Dir["#{RAILS_ROOT}/app/jobs"]
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.
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...
