Sortable List in Rails

Create a drag and droppable List in Rails

	const previewImageOnFileSelect = () => {
	// we select the photo input
	const input = document.getElementById('photo-input');
	if (input) {
	// we add a listener to know when a new picture is uploaded
	input.addEventListener('change', () => {
	// we call the displayPreview function (who retrieve the image url and display it)
	displayPreview(input);
	})
	}

	class BaseRepo
	def initialize(csv_file)
	@csv_file = csv_file
	@elements = []
	@next_id = 1
	load_csv if File.exist?(@csv_file)
	end

	def create(element)
	element.id = @next_id

	class Patient
	attr_accessor :room, :id

	def initialize(attributes = {})
	@id = attributes[:id]
	@name = attributes[:name]
	@cured = attributes[:cured] \|\| false
	end
	end

	something.gsub(/src=(?<url>[^\s]+)/, 'src="" data-src=\k<url> class="lozad"')

	# here \k<something> where something is the name of the group in your regex.
