You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: workflows_controller.rb
    path of file: ./repos/workflow_core/test/dummy/app/controllers
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

class WorkflowsController < ApplicationController
  layout "application"

  before_action :set_workflow, only: %i[show edit update destroy]

  # GET /workflows
  def index
    
    
  def edit; end

  # POST /workflows
  def create
    @workflow = Workflow.new(workflow_params)

    if @workflow.save
      redirect_to workflow_url(@workflow), notice: "workflow was successfully created."
    else
      render :new
    end
  end
