NameError: undefined local variable or method `user' - ruby-on-rails

Question

I'm writing an app using RoR, using gem Devise for user authentication. I'm trying to test user behaviour when he signed in the app and have next error:
User::TransactionsController when logged in when its own record GET #show assigns the requested instance as #instance
Failure/Error: let(:transaction) { FactoryGirl.create(:transaction, user_id: user.id) }
NameError:
undefined local variable or method `user' for #<RSpec::ExampleGroups::UserTransactionsController::WhenLoggedIn::WhenItsOwnRecord::GETShow:0x00000004d77220>
My tests start with:
RSpec.describe User::TransactionsController, type: :controller do
render_views
before { sign_in FactoryGirl.create :user }
let(:transaction_category) { FactoryGirl.create(:transaction_category) }
let(:transaction) { FactoryGirl.create(:transaction, user_id: user.id) }
......
end
My factory:
FactoryGirl.define do
factory :transaction do
date '2016-01-08'
comment 'MyString'
amount 1
transaction_category
trait :invalid do
amount nil
end
end
end
My TransactionsController looks like:
class User::TransactionsController < ApplicationController
before_action :authenticate_user!
before_action :find_transaction, only: [:show, :edit, :destroy, :update]
def new
#transaction = current_user.transactions.build
end
def show
end
def create
#transaction = current_user.transactions.build(transaction_params)
if #transaction.save
redirect_to user_transaction_url(#transaction)
else
render :new
end
end
def index
#transactions = current_user.transactions
end
def edit
end
def destroy
#transaction.destroy
redirect_to user_transactions_url
end
def update
if #transaction.update(transaction_params)
redirect_to user_transaction_url
else
render :edit
end
end
private
def transaction_params
params.require(:transaction).permit(:amount, :date, :comment,
:transaction_category_id)
end
def find_transaction
#transaction = current_user.transactions.find(params[:id])
end
end
Thanks!

You need to define user
RSpec.describe User::TransactionsController, type: :controller do
render_views
user = FactoryGirl.create( :user )
before { sign_in( user ) }
let(:transaction_category) { FactoryGirl.create(:transaction_category) }
let(:transaction) { FactoryGirl.create(:transaction, user_id: user.id) }
......
end
