ruby-on-rails-3.1

Background I have an app that I recently updated to Rails 3.2.1 (from Rails 3.0.x) and have refactored the JS and CSS assets to make use of the new asset pipeline. The app is hosted on Heroku with the Celadon Cedar stack. App Config I keep application specific configuration in a YAML file called app_config.yml and load it into a global APP_CONFIG variable using an initializer: # config/initializers/load_app_config.rb app_config_contents = YAML.load_file("#{Rails.root.to_s}/config/app_config.yml") app_config_contents["default"] ||= {} APP_CONFIG = app_config_contents["default"].merge( app

I'm trying to deploy a Rails 3.1 application for the first time on Heroku. I set it to the Cedar stack, removed the sqlite3 gem but when I push the code to Heroku I get this error: -----> Installing dependencies using Bundler version 1.1.rc Running: bundle install --without development:test --path vendor/bundle --deployment Fetching gem metadata from http://rubygems.org/ ....... (...) Installing rails (3.1.0) Installing sqlite3 (1.3.4) with native extensions Unfortunately, a fatal error has occurred. Please report this error to the Bundler issue tracker at https://github.com/carlhuda/bundler

I recently branched one of my Rails 3.0 projects with the 3.1 rc1 to try the new assets pipeline. I've been using Sass in the project before going 3.1 so I've been setting up some variables and functions in a separate configure file and let all my other sass files import that one file at the first line. This has been working out great to not repeat some color codes and general geometry through in the stylesheets. Problem is now with the new Assets Pipeline is that as I've understood it converts the ".css.sass" files to raw css before appending it to the rest of the code. So if i specify, in my

Similar to Integrating CKEditor with Rails 3.1 Asset Pipline I am trying to integrate ckeditor with my rails 3.2 application. I have all ckeditor files copied under /app/assets/javascripts/ckeditor/* . I have the following lines in my application.js and application.js is included in my layout file: //= require jquery //= require jquery_ujs //= require ckeditor/ckeditor //= require_self Taken it from the answer to Integrating CKEditor with Rails 3.1 Asset Pipline I can understand that I need to add something like: config.assets.precompile += your_files to my development.rb file so that all the

I am creating a pdf file in the latest version of the Prawn library (v1.0.1rc) in Rails (3.1.1) and when I run my code it generates the PDF into the root of the application. I don't want this. I want it to render the output into user's browser window, without saving it locally to the server. Please tell me how I can achieve this. Here are my files: views/foo/show.pdf.erb : <%= require 'prawn' pdf = Prawn::Document.new(:page_size => 'LETTER', :page_layout => :landscape, :margin => 50, :top_margin => 20, :bottom_margin => 50) ..... render_file("foo.pdf") %> controllers/foo_controller : class

I'm getting these warnings when trying to use sass in Rails 3.1 rc1. WARN: tilt autoloading 'sass' in a non thread-safe way; explicit require 'sass' suggested. WARN: tilt autoloading 'sass/plugin' in a non thread-safe way; explicit require 'sass/plugin' suggested. This is my Gemfile. gem "rails", "~> 3.1.0.rc1" gem "haml" gem "sass" I've tried to create a file called sass.rb inside the config/initializers containing this code. require "sass" Changing the Gemfile to this. gem "rails", "~> 3.1.0.rc1" gem "haml" gem "sass", require: false But the warnings remains. Anyone knows how to solve it? I

I use @import 'd partial sheets to organize my css/sass: /app /assets /stylesheets _constants.sass _layout.sass ... app.css.sass app.css.sass: @import _constants.sass // basic styles @import _layout.sass @import ... app.css.sass has an @import rule for _layout.sass , which allows me to share mixins and variables amongst the raw sass files before they're complied down into app.css The problem is that Rails doesn't recognize changes to the @import 'd partials ( _layout.sass ) and won't regenerate app.css until I make a change to the actual app.css.sass file itself. This dramatically slows down
