Dani needs a rest after rest

Everything passes. Just want to make sure that nothing is redundant in my paths. 
This is a late review so you probably have changed your MO on this, but remember, instantiate then save so that you can check for errors.

```ruby
post '/contacts/:id/addresses' do
  
    @contact = Contact.find(params[:id])
    @address = Address.new(params[:address])

    if @address.save
      @contact.addresses << @address
      redirect "/contacts/#{params[:id]}"
    else
      erb :"addresses/new"
    end
end
```
