Datasette 1.0a24. New Datasette alpha this morning. Key new features:
- Datasette's
Requestobject can now handlemultipart/form-datafile uploads via the new await request.form(files=True) method. I plan to use this for adatasette-filesplugin to support attaching files to rows of data. - The recommended development environment for hacking on Datasette itself now uses uv. Crucially, you can clone Datasette and run
uv run pytestto run the tests without needing to manually create a virtual environment or install dependencies first, thanks to the dev dependency group pattern. - A new
?_extra=render_cellparameter for both table and row JSON pages to return the results of executing the render_cell() plugin hook. This should unlock new JavaScript UI features in the future.
More details in the release notes. I also invested a bunch of work in eliminating flaky tests that were intermittently failing in CI - I think those are all handled now.
