Have a Ruby on Rails 5.1.4 project with a single model. The application does not compile my app/assets/javascripts/posts.es6.erb file.
The idea is to pass a Ruby value to a ES6 Javascript bridging it with ERB like so: console.log('<%= Rails.env %>').
When changing my file to app/assets/javascripts/posts.js.erb it works fine but the es6 extension fails.
Rails just seems to silently ignore my es6.erb file.
Can anyone help?

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.
Im trying to put the bootstrap source files in my rails project but I am not seeing an "assets" folder in my app folder. Are the Image, Javascript, and CSS folders in "public" the same thing? If not then where do I put the source files? I am using ruby version 1.9.2-p290, rails version 3.0.19, and bootstrap version 2.3.2. Not sure if that makes a difference or not.
Why don't you just use a bootstrap gem like bootstrap-sass instead?
Look at this project: twitter-bootstrap-rails
It is an easy way to set up bootstrap in your Ruby on Rails project.
i am trying to use sass in a rails 3.0.1 project that i am working on. I install the gem but when i create a scss file and add some style nothing happens. I've been searching for an answer and it seems others have haml installed as well, do I need this?
I think you should add the assets pipeline (Sprockets) in addition to SASS.
Here is a gist that explains the setup for Rails 3.0.x.

When I use Rails with YAML I change boot.rb with
require "yaml"
YAML::ENGINE.yamler = "syck"
It works fine with normal Ruby.
When I transfer the application from Ruby to JRuby, it doesn't work.
Where should I write these lines in JRuby?
Syck is a native gem. a gem that builds native extensions that is. jRuby and native extensions do not mix. Just don't use that syck snippet and your jRuby problem should go away.
I am trying to implement a gem called stanfordparser which can be found here: http://stanfordparser.rubyforge.org/
It is a ruby wrapper for a java natural language parser
I am developing in netbeans using ruby on rails / jruby on a windows 7 machine. My web app works fine otherwise, but when I try to add the parser wrapper it breaks.
Here is the code that is causing a problem:
gem 'stanfordparser'
def show
parser = StanfordParser::LexicalizedParser.new
#words = parser.apply("This is a sentence.")
end
this is in the taskscontroller
and when I go to tasks/show (which, if i remove this code, works fine) I get the following error
uninitialized constant TasksController::StanfordParser
I have made sure the gem is installed in netbeans
I am very new to ruby on rails, and teaching myself, so it may be something obvious
Thanks!
EDIT: I checked my glassfish server logs and it says
SEVERE: Missing these required gems:
stanfordparser
which is weird because I've installed the gem using netbeans, I've done rake gems:install and netbeans says the gem is installed. I've checked in netbeans gems folder and the gem is installed there.
EDIT 2:
So, after a lot of research and head banging, I've decided to simplify things a bit by just trying to use jruby to implement the java classes, now I need to figure out how to import the stanfordparser java classes (there are at least 50), I think I need to compress all the classes into a jar so that jruby can load it. maybe.
If you are using Rails 3 then the gem 'stanfordparser' statement needs to be specified in Bundler's Gemfile within the project's root. Otherwise, for Rails 2.x you need a config.gem 'stanfordparser' statement within config/environment.rb.
I was able to solve my problem the following way:
instead of using the stanfordparser ruby wrapper (which implements java ruby bridge to connect the java stanford parser to pure ruby), I use jruby to just implement the java from the stanford parser.
the code that ended up working:
include Java
require 'C:\\Stanford-Parser\\Current\\stanford-parser.jar'
require 'rubygems'
include_class 'edu.stanford.nlp.parser.lexparser.LexicalizedParser'
lp = LexicalizedParser.new(args) #args is the arguments, not copied here
