This release includes a couple new field types and greatly improved
C extension support for both speedups and SQLite enhancements. Also
includes some work, suggested by @foxx, to remove some places where
Proxy was used in favor of more obvious APIs.
New features
- C extension speedups now enabled by default, includes faster
implementations for dict and tuple QueryResultWrapper classes,
faster date formatting, and a faster field and model sorting.
- C implementations of SQLite functions is now enabled by default.
SQLite extension is now compatible with APSW and can be used in
standalone form directly from Python.
- SQLite C extension now supports murmurhash2.
- UUIDField is now supported for SQLite and MySQL, using text and
varchar respectively, thanks @foxx!
- Added BinaryField, thanks again, @foxx!
- Added PickledField to playhouse.fields.
- ManyToManyField now accepts a list of primary keys when adding or
removing values from the through relationship.
- Added support for SQLite table-valued functions using the
sqlite-vtfunc library.
- Significantly simplified the build process for compiling the
C extensions.
Backwards-incompatible changes
- Instead of using a Proxy for defining circular foreign key
relationships, you now need to use DeferredRelation.
- Instead of using a Proxy for defining many-to-many through tables,
you now need to use DeferredThroughModel.
- SQLite Virtual Models must now use Meta.extension_module and
Meta.extension_options to declare extension and any options.
- MySQL database will now issue COMMIT statements for SELECT queries.
Bugs fixed
- #766, fixed bug with PasswordField and Python3. Fuck Python 3.
- #768, fixed SortedFieldList and remove_field(). Thanks @klen!
- #771, clarified docs for APSW.
- #773, added docs for request hooks in Pyramid
- #774, prefetch() only loads first ForeignKeyField
for a given relation.
- #782, fixed typo in docs.
- #791, foreign keys were not correctly handling coercing to
the appropriate python value.
- #792, cleaned up some CSV utils code.
- #798, cleaned up iteration protocol in QueryResultWrappers.
- #806, not really a bug, but MySQL users were clowning around
and needed help.
2.7.4
This is another small release which adds code to automatically build
the SQLite C extension if libsqlite is available. The release also
includes:
- Support for UUIDField with SQLite.
- Support for registering additional database classes with the db_url
module via register_database.
- prefetch() supports fetching multiple foreign-keys to the same model
class.
