From the documentation get or create     get or create   a person with similar first names   p  created   Person objects get or create      first name  John       last name  Lennon       defaults   birthday   date 1940  10  9         get or create   didn t have to create an object   gt  gt  gt  created False   Explanation   Fields to be evaluated for similarity  have to be mentioned outside defaults  Rest of the fields have to be included in defaults  In case CREATE event occurs  all the fields are taken into consideration   It looks like you need to be returning into a tuple  instead of a single variable  do like this   customer source created   Source objects get or create name  Website
