## Summary Fix knowledge-base chat retrieval when no individual document IDs are selected. ## Root Cause `async_chat()` initialized `doc_ids` as an empty list when the request did not explicitly select documents. That empty list was then forwarded into retrieval as an active `doc_id` filter, effectively becoming `doc_id IN []` and suppressing all chunk matches. ## Changes - treat missing selected document IDs as `None` instead of `[]` - keep explicit document filtering when IDs are actually provided - add regression coverage for the shared chat retrieval path ## Validation - `python3 -m py_compile api/db/services/dialog_service.py test/unit_test/api/db/services/test_dialog_service_use_sql_source_columns.py` - `.venv/bin/python -m pytest test/unit_test/api/db/services/test_dialog_service_use_sql_source_columns.py` - manually verified that chat completions again inject retrieved knowledge into the prompt --------- Co-authored-by: Yingfeng <yingfeng.zhang@gmail.com>
(1). Deploy RAGFlow services and images
https://ragflow.io/docs/build_docker_image
(2). Configure the required environment for testing
Install Python dependencies (including test dependencies):
uv sync --python 3.12 --only-group test --no-default-groups --frozen
Activate the environment:
source .venv/bin/activate
Install SDK:
uv pip install sdk/python
Modify the .env file: Add the following code:
COMPOSE_PROFILES=${COMPOSE_PROFILES},tei-cpu
TEI_MODEL=BAAI/bge-small-en-v1.5
RAGFLOW_IMAGE=infiniflow/ragflow:v0.24.0 #Replace with the image you are using
Start the container(wait two minutes):
docker compose -f docker/docker-compose.yml up -d
(3). Test Elasticsearch
a) Run sdk tests against Elasticsearch:
export HTTP_API_TEST_LEVEL=p2
export HOST_ADDRESS=http://127.0.0.1:9380 # Ensure that this port is the API port mapped to your localhost
pytest -s --tb=short --level=${HTTP_API_TEST_LEVEL} test/testcases/test_sdk_api
b) Run http api tests against Elasticsearch:
pytest -s --tb=short --level=${HTTP_API_TEST_LEVEL} test/testcases/test_http_api
(4). Test Infinity
Modify the .env file:
DOC_ENGINE=${DOC_ENGINE:-infinity}
Start the container:
docker compose -f docker/docker-compose.yml down -v
docker compose -f docker/docker-compose.yml up -d
a) Run sdk tests against Infinity:
DOC_ENGINE=infinity pytest -s --tb=short --level=${HTTP_API_TEST_LEVEL} test/testcases/test_sdk_api
b) Run http api tests against Infinity:
DOC_ENGINE=infinity pytest -s --tb=short --level=${HTTP_API_TEST_LEVEL} test/testcases/test_http_api
