Model.save_base() is called directly when loading fixtures and assumes existing rows will be updated. Branching of "raw" allows to maintain the optimization introduced in #29260 while supporting this edge case. Regression in 85458e94e38c20e57939947ee515a1a53689659f. Thanks Reupen Shah for the report.

******** Models for test_data.py ***********

The following classes are for testing basic data marshalling, including
|

NULL values, where allowed.
|
|
The basic idea is to have a model for each Django data type.
