PWSdelta / rspec_model_testing_template.rb

Last active July 29, 2025 13:52

Rails Rspec model testing skeleton & cheat sheet using rspec-rails, shoulda-matchers, shoulda-callbacks, and factory_girl_rails. Pretty much a brain dump of examples of what you can (should?) test in a model. Pick & choose what you like, and please let me know if there are any errors or new/changed features out there. Reddit comment thread: http…

	# This is a skeleton for testing models including examples of validations, callbacks,
	# scopes, instance & class methods, associations, and more.
	# Pick and choose what you want, as all models don't NEED to be tested at this depth.
	#
	# I'm always eager to hear new tips & suggestions as I'm still new to testing,
	# so if you have any, please share!
	#
	# This skeleton also assumes you're using the following gems:

PWSdelta / tweets_controller.rb

Last active December 21, 2015 14:58

A Ruby on Rails controller action showing how to fetch a group of Tweets/followers/friends & send them to a view. You can also create Tweets with this controller & the Twitter API, but you'll need to ensure your callback URL is correct. Follow the documentation for that.

	class TweetsController < ApplicationController

	before_action :create_client

	def index
	batch_size = 10
	@twitter_handle = "dhh"

	@tweets = @client.user_timeline(@twitter_handle).take(batch_size)
	@friends = @client.friends(@twitter_handle).take(batch_size)

PWSdelta / ruby-open-uri-request.rb

Created December 9, 2013 17:16

4-line Ruby script that uses open-uri to fetch the contents of a URL & displays it in the console. This is the foundation for all web requests, whether to scrape a page, request a JSON response, and more.

	# http://ruby-doc.org/stdlib-2.0.0/libdoc/open-uri/rdoc/OpenURI.html
	require 'open-uri'

	# Go fetch the contents of a URL & store them as a String
	response = open('http://www.example.com').read

	# "Pretty prints" the result to look like a web page instead of one long string of HTML
	URI.parse(response).class

	# Print the contents of the website to the console

Created December 9, 2013 22:44

A Ruby web scraping script that visits a GitHub trending repos page, scrapes the data for the 25 repos, loads them into a CSV, and then reads from the CSV & creates a hash with each repo's data.

	require 'mechanize'
	require 'csv'

	# Load up the trending Ruby repos on GitHub from the last month.
	url_to_scrape = "https://github.com/trending?l=ruby&since=monthly"
	# Snag the website with Mechanize & parse it into an XML document we can query.
	page = Mechanize.new.get(url_to_scrape)

	# Set the name of the CSV we'll create & load from.
	file = "repo_data.csv"

PWSdelta / json_response_handling_ruby.rb

Created December 11, 2013 14:20

Ruby script that uses open-uri to fetch the contents of a JSON endpoint, uses the JSON gem to parse the string into a Ruby array & prints some of the records. This is the foundation for all web API requests, so feel free to use it in the future.

	require 'open-uri'
	# https://github.com/flori/json
	require 'json'
	# http://stackoverflow.com/questions/9008847/what-is-difference-between-p-and-pp

	require 'benchmark'
	# http://www.ruby-doc.org/stdlib-2.0.0/libdoc/bigdecimal/rdoc/BigMath.html
	require 'bigdecimal/math'


	# Set the number of iterations to run. The underscore here is used as a substitute for normal comma so Ruby interprets the number correctly.
