Devise - "Brush" system tasks per user

Question

I’m making a simple little application where the user can delete, edit, view and create tasks, tasks have description, title and date to be executed.

I have implemented Aim to register users and login users, but I’m having difficulty to "brush" the tasks per user, IE, the user will login and can view, edit and delete only the tasks created by him.

My schema is:

ActiveRecord::Schema.define(version: 20170407164641) do

  # These are extensions that must be enabled in order to support this database
  enable_extension "plpgsql"

  create_table "tarefas", force: :cascade do |t|
    t.string   "titulo"
    t.text     "descricao"
    t.datetime "data"
    t.integer  "user_id"
    t.datetime "created_at", null: false
    t.datetime "updated_at", null: false
    t.index ["user_id"], name: "index_tarefas_on_user_id", using: :btree
  end

  create_table "users", force: :cascade do |t|
    t.string   "email",                  default: "", null: false
    t.string   "encrypted_password",     default: "", null: false
    t.string   "reset_password_token"
    t.datetime "reset_password_sent_at"
    t.datetime "remember_created_at"
    t.integer  "sign_in_count",          default: 0,  null: false
    t.datetime "current_sign_in_at"
    t.datetime "last_sign_in_at"
    t.inet     "current_sign_in_ip"
    t.inet     "last_sign_in_ip"
    t.datetime "created_at",                          null: false
    t.datetime "updated_at",                          null: false
    t.index ["email"], name: "index_users_on_email", unique: true, using: :btree
    t.index ["reset_password_token"], name: "index_users_on_reset_password_token", unique: true, using: :btree
  end

end

I used belongs_to :user and has_many :tasks.

My task force controller:

    class TarefasController < ApplicationController

    before_filter :authenticate_user!

    def index
        @tarefa = Tarefa.all
    end

    def show
        @tarefa = Tarefa.find(params[:id])

     end

    def new
        @tarefa = Tarefa.new
    end

    def edit
        @tarefa = Tarefa.find(params[:id])
    end

    def create
         @tarefa = Tarefa.new(tarefa_params)
         @user = current_user
         if @tarefa.save
            redirect_to @tarefa
         else
            render 'new'
         end
    end

    def update
        @tarefa = Tarefa.find(params[:id])
        if @tarefa.update(tarefa_params)
            redirect_to @tarefa
        else
            render 'edit'
        end
    end

    def destroy
        @tarefa = Tarefa.find(params[:id])
        @tarefa.destroy

        redirect_to tarefas_path
    end

    private
      def tarefa_params
        params.require(:tarefa).permit(:titulo, :descricao, :data)
      end
end

Answer 1

def index
  @tarefas = current_user.tarefas
end


def create
     @tarefa = Tarefa.new(tarefa_params)
     @tarefa.user = current_user
     if @tarefa.save
        redirect_to @tarefa
     else
        render 'new'
     end
end
