Description (last modified by Ben Cole)

There exist multiple use cases where a database will generate values for a field/column. Most RDBMSes expect that these columns be excluded from from INSERT and UPDATE statements. However they still need to be included in SELECT statements.

The proposal therefore is to add a readonly option to the base Field class that when True would strip these fields from being compiled to SQL during INSERTs and UPDATEs. This allows for a very simple change that covers all possible write queries that Django may perform (including bulk_*).

There exists a proof of concept ​https://github.com/novafloss/django-readonly-field
