ruby on rails - Created objects in Rspec test can be inspected but showing as blank? and !present? -

i have strange case i'm finding when i'm running rspec tests.

after doing my_model = mymodel.create, can my_model.inspect , create properties of object, when my_model.blank? or my_model.present? shows true , false respectively

i can further demonstrate strange behavior doing

find_test = mymodel.find(my_model.id) 

and same results - object can inspected, shows properties, registers blank , not present.

really weird , can't write reliable test behavior. how can "exist" both "blank" , not "present"?

here code showing output in comments:
