1. rails new <project_name> -d postgresql --skip-turbolinks --skip-spring -T

• -d postgresql sets up the project to use PostgreSQL
• --skip-turbolinks & --skip-spring creates a project that does not use turbolinks or spring
• -T skips the creation of the test directory and use of Test::Unit

2. In the Gemfile:

• Available to all environments:
  • gem 'figaro' - store environment variables securely across your app (docs)
  • Uncomment gem 'bcrypt', '~> 3.1.7' if you will be hosting your own user accounts with passwords (docs)

When hiring Ruby on Rails programmers, knowing the right questions to ask during an interview was a real challenge for me at first. In 30 minutes or less, it's difficult to get a solid read on a candidate's skill set without looking at code they've previously written. And in the corporate/enterprise world, I often don't have access to their previous work.

To ensure we hired competent ruby developers at my last job, I created a list of 15 ruby questions -- a ruby measuring stick if you will -- to select the cream of the crop that walked through our doors.

What to expect

Candidates will typically give you a range of responses based on their experience and personality. So it's up to you to decide the correctness of their answer.

#unscoped
  Class Item < ActiveRecord::Base
  default_scope { where(status: "active") }
  
  Item.all - returns only items with an active status
  Item.unscoped.all - returns all items, regardless of whether they pass the validation
  
#Find using primary key
  #can take an array as an arg to return client.id=1 and client.id=10
  client = Client.find([1, 10])

Module 1 Week 3 Diagnostic

This exercise is intended to help you assess your progress with the concepts and techniques we've covered during the week.

For these questions, write a short snippet of code that meets the requirement. In cases where the question mentions a "given" data value, use the variable given to refer to it (instead of re-writing the information).
