Setting up AppSignal on Shelly Cloud

Setting up AppSignal on Shelly Cloud

To set up AppSignal on Shelly Cloud, you first have to add both the dotenv-rails and the appsignal gem to your Gemfile. Make sure that the dotenv-rails gem is the very first gem in your Gemfile as it will set up important environment variables as soon as it is required.

# Gemfile

source 'https://rubygems.org'

gem 'dotenv-rails'

benedikt / array_each.rb
Created Oct 23, 2013
In Rubinius, the `Array#each` method does not enumerate elements that are added while enumerating. Is this intentional or a bug?
View array_each.rb
array = [1, 2]
array.each { |n| array << n * 2; break if n > 10 }

Is this a mongoid bug or a feature?

benedikt / projects_controller_spec.rb
Created Jul 17, 2012
I wish this would just work...
View projects_controller_spec.rb
require 'spec_helper'
describe ProjectsController do
let(:project) { double(:project) }
let(:projects) { [project] }
describe 'GET show' do
let(:params) { { :id => 1, :format => :json } }
You can’t perform that action at this time.
