The for_save flag wasn't properly propagated when resolving expressions, which prevented get_db_prep_save() from being called in some cases. This affected fields like JSONField where None would be saved as JSON null instead of SQL NULL. Regression in 00c690efbc0b10f67924687f24a7b30397bf47d9. Thanks to David Sanders and Simon Charette for reviews. Co-authored-by: Adam Johnson <me@adamj.eu>
The documentation in this tree is in plain text files and can be viewed using any text file viewer. It uses `ReST`_ (reStructuredText), and the `Sphinx`_ documentation system. This allows it to be built into other forms for easier viewing and browsing. To create an HTML version of the docs: * Install Sphinx (using ``python -m pip install Sphinx`` or some other method). * In this docs/ directory, type ``make html`` (or ``make.bat html`` on Windows) at a shell prompt. The documentation in ``_build/html/index.html`` can then be viewed in a web browser. .. _ReST: https://docutils.sourceforge.io/rst.html .. _Sphinx: https://www.sphinx-doc.org/
