Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

[0.8.0] - 2023-01-20

Added

  • SQL: Support for the SQLite dialect.

Changed

  • SQL: Refactored SQL support

    • The AstToSqlVisitor now implements basic, standard SQL and functions as a base class for dialects.
    • The Athena dialect now lives in AstToAthenaSqlVisitor.

[0.7.2] - 2022-12-19

Fixed

  • SQLAlchemy; Return a 1.x Query if a 1.x Query is passed in the shorthand.

[0.7.1] - 2022-12-16

Fixed

  • SQLAlchemy; Fix accidentally dropped support for 1.x style queries.

[0.7.0] - 2022-10-28

Added

  • A new visitor that roundtrips OData AST back to an OData query string.
  • SQLAlchemy: Support for SQLAlchemy Core through a new visitor.

Changed

  • Some lower-level SQLAlchemy related modules have been reorganized to facilitate SQLAlchemy Core support.

[0.6.0] - 2022-10-28

Changed

  • Django; Rework Django query transformer to use Django query nodes more. With the release of Django 4, we can now use Lookup, Function, and other Django query nodes in queries directly instead of relying on the keyworded syntax. For older Django versions, we can still transform those nodes to the keyworded syntax.
  • Deps; Upgraded Sphinx and the ReadTheDocs theme.

Fixed

  • Django; Support comparisons of boolean funcs to booleans (e.g. contains(a, 'b') eq true)

[0.5.2] - 2022-03-14

Changed

  • Deps; Upgraded pytest.

Fixed

  • SQLAlchemy; Fixed datetime extract functions.

[0.5.1] - 2022-02-28

Fixed

  • QA; Remove type:ignore from grammar.py and fix resulting type issues.

[0.5.0] - 2022-02-28

Added

  • Parser: Rudimentary OData namespace support.
  • AST: Literal nodes now have a py_val getter that returns the closest Python approximation to the OData value.
  • QA: Added full typing support.

Changed

  • QA: Upgraded linting libraries.

[0.4.2] - 2021-12-19

Added

  • Docs: Include contribution guidelines and changelog in the main documentation.

Changed

  • Docs: Use ReStructuredText instead of markdown where possible, for easier interaction with Sphinx.

Removed

  • Docs: Removed the Myst dependency as we're no longer mixing markdown into our docs.
  • Dev: Removed the moto and Faker dependencies as they weren't used.

[0.4.1] - 2021-07-16

Added

  • Added shorthands for the most common use cases: Applying an OData filter straight to a Django QuerySet or SQLAlchemy query.

Fixed

  • Cleared warnings produced in SLY by wrong regex flag placement.

[0.4.0] - 2021-05-28

Changed

  • Raise a new InvalidFieldException if a field in a query doesn't exist.

Fixed

  • Allow AliasRewriter to recurse into Attribute nodes, in order to replace nodes in the Attribute's ownership chain.

[0.3.0] - 2021-05-17

Added

  • Added NodeTransformers, which are like NodeVisitors but replace visited nodes with the returned value.
  • Initial API documentation.

Changed

  • The AstTo{ORMQuery} visitors for SQLAlchemy and Django now have the same interface.
  • AstToDjangoQVisitor now builds subqueries for any()/all() itself, instead of relying on SubQueryTokens and a seperate visitor.
  • Made all AST Nodes frozen (read-only), so they can be hashed.
  • Replaced field_mapping on the ORM visitors with a more general AliasRewriter based on the new NodeTransformers.
  • Refactored IdentifierStripper to use the new NodeTransformers.

[0.2.0] - 2021-05-05

Added

  • Transform OData queries to SQLAlchemy expressions with the new AstToSqlAlchemyClauseVisitor.

Changed
