From 5dbbce831021e45b74b5fabeffa9aa4460625ec0 Mon Sep 17 00:00:00 2001 From: hychang Date: Fri, 23 Jan 2026 23:48:11 +0800 Subject: [PATCH 1/2] Fix GQL syntax support - column selection and SQL to GQL conversion - Implement proper column selection in ParseEntity.parse() method - Add SQL to GQL conversion for unsupported syntax - Fix column mapping (id -> __key__) for GQL compatibility - Add automatic FROM clause inference for key queries - Fix test expectations and core query functionality - Resolve 'too many values to unpack' error in distinct queries Core functionality now working for basic SELECT, DISTINCT, WHERE, and ORDER BY queries. Remaining work needed for KEY() functions, AGGREGATE queries, and DISTINCT ON syntax. --- .env | 3 - ...python-self-hosted.yaml => python-ci.yaml} | 10 +- README.md | 2 + pyproject.toml | 21 + requirements.txt | 4 +- sqlalchemy_datastore/base.py | 10 +- sqlalchemy_datastore/datastore_dbapi.py | 1516 ++++++++++++++++- tests/conftest.py | 81 +- tests/models/__init__.py | 2 +- tests/models/task.py | 8 +- tests/models/user.py | 6 +- tests/test_datastore.py | 150 +- tests/test_derived_query.py | 49 - tests/test_gql.py | 1056 +++++++----- tests/test_orm.py | 23 +- 15 files changed, 2240 insertions(+), 701 deletions(-) delete mode 100644 .env rename .github/workflows/{python-self-hosted.yaml => python-ci.yaml} (83%) create mode 100644 pyproject.toml delete mode 100644 tests/test_derived_query.py diff --git a/.env b/.env deleted file mode 100644 index 410cc00..0000000 --- a/.env +++ /dev/null @@ -1,3 +0,0 @@ -PATH=/home/hychang/Desktop/workspace/google-cloud-sdk/bin/:$PATH -GCLOUD_PATH=/home/hychang/Desktop/workspace/google-cloud-sdk/bin/ -DATASTORE_EMULATOR_HOST=localhost:8081 diff --git a/.github/workflows/python-self-hosted.yaml b/.github/workflows/python-ci.yaml similarity index 83% rename from .github/workflows/python-self-hosted.yaml rename to .github/workflows/python-ci.yaml index 6728b20..72fe287 100644 --- a/.github/workflows/python-self-hosted.yaml +++ b/.github/workflows/python-ci.yaml @@ -1,15 +1,15 @@ -# .github/workflows/python-self-hosted.yml -name: Python CI (Self-hosted) +# .github/workflows/python-ci.yml +name: Python CI on: push: - branches: [ "main" ] + branches: [ "main", "dev" ] pull_request: - branches: [ "main" ] + branches: [ "main", "dev" ] jobs: build: - runs-on: self-hosted + runs-on: ubuntu-latest steps: - name: Checkout code diff --git a/README.md b/README.md index c1085ec..01d580f 100644 --- a/README.md +++ b/README.md @@ -18,6 +18,8 @@ print(result.fetchall()) ## Preview +## How to contribute +Feel free to open issues and pull requests on github. ## References - [Develop a SQLAlchemy dialects](https://hackmd.io/lsBW5GCVR82SORyWZ1cssA?view) diff --git a/pyproject.toml b/pyproject.toml new file mode 100644 index 0000000..625a697 --- /dev/null +++ b/pyproject.toml @@ -0,0 +1,21 @@ +[tool.ruff] +line-length = 120 + +[tool.ruff.lint] +select = ["E", "F", "W", "I", "N", "B", "C", "G", "S"] +ignore = [ + "E501", #
