Created August 18, 2016 13:27 — forked from myronmarston/ways_to_use_vcr.rb
Ways to use VCR for a request made by a let block
# 1) Use VCR.use_cassette in your let block. This will use
# the cassette just for requests made by creating bar, not
# for anything else in your test.
let(:foo) { VCR.use_cassette("foo") { create(:bar) } }
it "uses foo" do
foo
end
# 2) Wrap the it block that uses #foo in VCR.use_cassette.

Why `Rails.application.config.action_mailer` sucks?
# config/initilizers/action_mailer.rb
ActionMailer::Base.default_url_options = {}
Rails.application.config.action_mailer.default_url_options = { host: "localhost:3001" }
# console
[1] pry(main)> Rails.application.config.action_mailer[:default_url_options]
=> {:host=>"localhost:3001"}
[2] pry(main)> ActionMailer::Base.default_url_options
=> {}

The following tutorial explains how to use Heroku's new 'Hostname SSL' option on your Heroku project. Before we begin, let's list what we're using here:
* Heroku Hostname SSL
* GoDaddy Standard SSL Certificate
* Zerigo DNS
