How to reload a variable defined by let

Question

A user has many comments, so I would like to have a factory user with a comment associated to it (user_with_comment):

factory :user, class: User  do |t|
  ...
  factory :user_with_comment do |t|
    after(:create) do |user|
      FactoryGirl.create(:comment, user_id: user.id)
    end
end

It works fine... when I call FactoryGirl.create(:user_with_comment), it creates the user and the related comment in my test db.

However, I'm facing some issues in the controller_spec:

Using let I have to reload the user to see the comment:

let(:user) { FactoryGirl.create(:user_with_comment) }
user.comments.size #=>0
user.reload
user.comments.size #=>1

One solution would be using before(:each), but it will create venda and comment before each test:

before(:each) do
  @user = FactoryGirl.create(:user_with_comment)
end
@user.comments.size #=>1

Or, I can reload the userbefore each test, but it will also hit the database:

let(:user) { FactoryGirl.create(:user_with_comment) }
before(:each) do
  user.reload
end

What is the best approach in this situation?

How about this?

let(:user) { FactoryGirl.create(:user_with_comment).reload }
