Update to specs

[danielfriis]

In the new version of rspec spec_helper has been split into two, and you should now require rails_helper instead in the top of all specs.

Also, in the spec below, you should call .as_json on event.ended_at, as you do with event.started_at, because both are converted to json.

# spec/requests/api/v1/events/events_spec.rb

require 'spec_helper'

describe 'GET /v1/events/:id' do
    it 'returns an event by :id' do
      event = create(:event)

      get "/v1/events/#{event.id}"

      expect(response_json).to eq( {

        'address' => event.address,
        'ended_at' => event.ended_at,
        'id' => event.id,
        'lat' => event.lat,
        'lon' => event.lon,
        'name' => event.name,
        'started_at' => event.started_at.as_json,
        'owner' => {
          'id' => event.owner.id
        }
      } )
    end
end

I wasn't sure where in the book or sample app to add this note so instead of a PR, I decided to add to this issue: I was getting Shoulda Matchers errors stating it didn't recognize it {should validate_presence_of(:lat)} The solution is when you make your rails_helper.rb file, you have to manually install Shoulda-matchers in my testing framework (it used to be installed automatically). For reference, my rails_helper.rb is as follows- the Shoulda-Matchers install info is at the bottom:

ENV['RAILS_ENV'] ||= 'test'
require File.expand_path('../../config/environment', __FILE__)
abort("The Rails environment is running in production mode!") if Rails.env.production?
require 'spec_helper'
require 'rspec/rails'
require 'webmock/rspec'
require 'shoulda/matchers'

Dir[Rails.root.join('spec/support/**/*.rb')].each { |f| require f }
