Setting foreign keys, yet record.association_name returning nil

Rails
1

Please help me to understand why this piece of rspec code is behaving
this
way. I am setting product_id to my record, and it is asserting true, but
yet record.product not returning anything.

product = FactoryGirl.create(:product)

post :create, {:tshirt =>
FactoryGirl.attributes_for(:tshirt).stringify_keys.merge(“product_id”=>
product.id.to_s) } #successful creation
expect(Tshirt.last.product_id).to eq(product.id) # asserts true
puts Tshirt.last.product #prints nothing
expect(Tshirt.last.product.size).to eq(product.size) # exception!!! it
says, product = nil

What do the following show?
puts TShirt.last.inspect
puts product.inspect
puts Tshirt.last.product.inspect

and copy/paste the start of t_shirt.rb showing the associations

Check how product is defined in the tshirt model. Also check the value
of
product.id, it may be nil for all we know and tshirt.product_id is also
nil
so they’re equal.
