Get early access RELEASE datasette 1.0a27 — An open source multi-tool for exploring and publishing data Two major changes in this new Datasette alpha. I covered the first of those in detail yesterday - Datasette no longer uses Django-style CSRF form tokens, instead using modern browser headers as described by Filippo Valsorda. The second big change is that Datasette now fires a new RenameTableEvent any time a table is renamed during a SQLite transaction. This is useful because some plugins (like datasette-comments) attach additional data to table records by name, so a renamed table requires them to react in appropriate ways. Here are the rest of the changes in the alpha: New actor= parameter for datasette.client methods, allowing internal requests to be made as a specific actor. This is particularly useful for writing automated tests. (#2688) New Database(is_temp_disk=True) option, used internally for the internal database. This helps resolve intermittent database locked errors caused by the internal database being in-memory as opposed to on-disk. (#2683) (#2684) The /<database>/<table>/-/upsert API (docs) now rejects rows with null primary key values. (#1936) Improved example in the API explorer for the /-/upsert endpoint (docs). (#1936) The /<database>.json endpoint now includes an "ok": true key, for consistency with other JSON API responses. call_with_supported_arguments() is now documented as a supported public API.
