Release History


Release 0.6.0

Build Status (Travis CI) Code Coverage Status (Codecov) Documentation Status (ReadTheDocs)

Bug Fixes

  • #87: Fixed a longstanding bug that prevented one-to-one relationships from being deserialized properly.

Other Changes

  • #89: Implemented support for display_name on relationships.
  • Updated test matrix to maintain test compability in the Python 3.4 environment.

Release 0.5.1

Build Status (Travis CI) Code Coverage Status (Codecov) Documentation Status (ReadTheDocs)

Bug Fixes

  • #80: Revised how the default deserializer functions for datetime.timedelta and datetime.datetime objects functions. When deserializing either, the default deserializer now starts by attempting to coerce the value to a datetime.timedelta using the Validator Collection timedelta() validator function, which supports the expression of amounts of time as both integers (e.g. 23 seconds) and strings (e.g. 00:00:23). If the object cannot be converted to a timedelta (if it is a complete / proper datetime with both a time and date value), the default deserializer will then revert to returning a datetime.datetime object.
  • #82: Revised the minimum version needed for the Validator Collection library to resolve a bug in iterable serialization/deserialization.

Other Changes

  • #84: Added Python 3.8 to test matrix.

Release 0.5.0

Build Status (Travis CI) Code Coverage Status (Codecov) Documentation Status (ReadTheDocs)

New Features

  • #68: Replaced serialization to dict with serialization to OrderedDict to preserve key ordering when serializing to JSON and YAML. The interface and interaction with OrderedDict should be 100% consistent with the behavior of past dict objects - just now their order will be preserved when on Python versions before 3.7.

Bug Fixes

  • #71: Modified default to_str() serializer function to coerce values to strings.
  • #73: Corrected a variety of mismatches in the default serializer/deserializer functions relating to datetime.timedelta objects and SQLAlchemy Interval and DATETIME type objects.
  • #75: Corrected a bug that may have introduced errors in applications using Python 3.7, SQLAlchemy 1.3+, and relying on AssociationProxy constructions in their models.
  • Updated the requirements.txt (which does not actually indicate utilization dependencies, and instead indicates development dependencies) to upgrade a number of libraries that had recently had security vulnerabilities discovered.

Release 0.4.0

Build Status (Travis CI) Code Coverage Status (Codecov) Documentation Status (ReadTheDocs)

Bug Fixes

  • #63: Fixed error handling for when SQLAlchemy returns UnsupportedCompilationError on certain data types.

New Features

  • #61: Added display_name attribute configuration option to re-write attribute names on serialization / de-serialization.
  • #62: Added support for multiple named configuration sets when using the meta configuration pattern.

Other Changes

  • Upgraded PyYAML version in requirements.txt.

Release 0.3.1

Build Status (Travis CI) Code Coverage Status (Codecov) Documentation Status (ReadTheDocs)

Bug Fixes

  • #58: Fixed problem where None values are mistakenly serialized to empty lists.
  • #57: Fixed problem where on_serialize functions were ignored for relationships.
  • #56: Fixed problem where relationships were not properly deserialized.

Other Changes

  • #26: Added Python 3.7 to test matrix.
  • Removed some unnecessary print statements.

Release 0.3.0

Build Status (Travis CI) Code Coverage Status (Codecov) Documentation Status (ReadTheDocs)

New Features

  • #35: Added BaseModel.dump_to_csv()
  • #35: Added BaseModel.dump_to_json()
  • #35: Added BaseModel.dump_to_yaml()
  • #35: Added BaseModel.dump_to_dict()
  • #34: Added BaseModel.configure_serialization()
  • #42: Added support for the programmatic generation of declarative model classes.
  • #41: Added support for the programmatic generation of Table objects.
  • #51: All *from_<format>() methods and functions now accept Path-like objects as inputs to load serialized data from a file.

Other Changes


Release 0.2.2

Build Status (Travis CI) Code Coverage Status (Codecov) Documentation Status (ReadTheDocs)

Bugs Fixed

  • #36: Fixed error in documentation (flask_sqlathanor.initialize_flask_sqlathanor() initially documented as flask_sqlathanor.initialize_sqlathanor()).

Other Changes

  • #32: Added Code of Conduct.

Release 0.2.1
