Add automatic discovery of ChromaDB databases in ./data/ subdirectories - Implement dual-mode UI: dropdown selector (default) and manual path entry - Show database metadata (collection count, size) in the selector - Add folder icons to database options for better visual clarity - Display helpful messages when no databases are found, pointing to utils/README.md - Persist user's mode preference (select vs manual) in localStorage - Add comprehensive unit tests for discovery functionality and routes This makes database selection more intuitive for new users while maintaining flexibility for advanced users to specify custom paths. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- chat_rag_explorer/rag_config_service.py | 91 +++++++ chat_rag_explorer/routes.py | 20 +- chat_rag_explorer/static/settings.js | 227 ++++++++++++++++- chat_rag_explorer/static/style.css | 54 ++++ chat_rag_explorer/templates/settings.html | 38 ++- data/chroma_db_sample/chroma.sqlite3 | Bin 6115328 -> 6115328 bytes tests/unit/test_rag_config_service.py | 211 ++++++++++++++++ tests/unit/test_rag_routes.py | 293 ++++++++++++++++++++++ 8 files changed, 925 insertions(+), 9 deletions(-) create mode 100644 tests/unit/test_rag_routes.py diff --git a/chat_rag_explorer/rag_config_service.py b/chat_rag_explorer/rag_config_service.py index 1a2a756..1d2be0c 100644 --- a/chat_rag_explorer/rag_config_service.py +++ b/chat_rag_explorer/rag_config_service.py @@ -178,6 +178,97 @@ def validate_local_path(self, path, request_id=None): 'details': {'exists': True, 'is_directory': True, 'has_database': True} } + def discover_databases(self, request_id=None): + """ + Discover ChromaDB databases in the ./data/ directory. + + Searches for subdirectories containing chroma.sqlite3 files and returns + metadata about each discovered database. + + Returns: + dict with: + -

compatibility in discover_databases tests MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The path mocking in tests was using Unix-specific path splitting ('/'), which caused failures on Windows. Fixed by: - Adding Path import to test module - Using Path(x).name instead of x.split('/')[-1] for cross-platform compatibility - Ensuring all path operations work with both forward and backslashes All 238 tests now pass on macOS, Ubuntu, and Windows. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- tests/unit/test_rag_config_service.py | 33 ++++++++++++++++----------- 1 file changed, 20 insertions(+), 13 deletions(-) diff --git a/tests/unit/test_rag_config_service.py b/tests/unit/test_rag_config_service.py index bffec2a..21238ce 100644 --- a/tests/unit/test_rag_config_service.py +++ b/tests/unit/test_rag_config_service.py @@ -6,6 +6,7 @@ """ import json import pytest +from pathlib import Path from unittest.mock import patch, MagicMock from chat_rag_explorer.rag_config_service import RagConfigService, DEFAULT_RAG_CONFIG @@ -391,7 +392,7 @@ def test_no_data_directory(self, tmp_path, monkeypatch): # Make data directory not exist fake_project = tmp_path / "fake_project" monkeypatch.setattr("chat_rag_explorer.rag_config_service.Path", - lambda x: fake_project / x.split('/')[-1]) + lambda x: fake_project / Path(x).name) result = service.discover_databases() @@ -407,9 +408,10 @@ def test_empty_data_directory(self, tmp_path, monkeypatch): # Mock the path resolution to use our temp directory def mock_path(path_str): - if "rag_config_service.py" in path_str: + p = Path(path_str) + if p.name == "rag_config_service.py": return tmp_path / "chat_rag_explorer" / "rag_config_service.py" - return Path(path_str) + return p monkeypatch.setattr("chat_rag_explorer.rag_config_service.Path", mock_path) @@ -431,9 +433,10 @@ def test_discovers_single_database(self, tmp_path, monkeypatch): # Mock path resolution def mock_path(path_str): - if "rag_config_service.py" in path_str: + p = Path(path_str) + if p.name == "rag_config_service.py": return tmp_path / "chat_rag_explorer" / "rag_config_service.py" - return Path(path_str) + return p monkeypatch.setattr("chat_rag_explorer.rag_config_service.Path", mock_path) @@ -464,9 +467,10 @@ def test_discovers_multiple_databases(self, tmp_path, monkeypatch): # Mock path resolution def mock_path(path_str): - if "rag_config_service.py" in path_str: + p = Path(path_str) + if p.name == "rag_config_service.py": return tmp_path / "chat_rag_explorer" / "rag_config_service.py" - return Path(path_str) + return p monkeypatch.setattr("chat_rag_explorer.rag_config_service.Path", mock_path) @@ -496,9 +500,10 @@ def test_ignores_files_in_data_dir(self, tmp_path, monkeypatch): # Mock path resolution def mock_path(path_str): - if "rag_config_service.py" in path_str: + p = Path(path_str) + if p.name == "rag_config_service.py": return tmp_path / "chat_rag_explorer" / "rag_config_service.py" - return Path(path_str) + return p monkeypatch.setattr("chat_rag_explorer.rag_config_service.Path", mock_path) @@ -530,9 +535,10 @@ def test_includes_collection_count(self, mock_client_class, tmp_path, monkeypatc # Mock path resolution def mock_path(path_str): - if "rag_config_service.py" in path_str: + p = Path(path_str) + if p.name == "rag_config_service.py": return tmp_path / "chat_rag_explorer" / "rag_config_service.py" - return Path(path_str) + return p monkeypatch.setattr("chat_rag_explorer.rag_config_service.Path", mock_path) @@ -559,9 +565,10 @@ def test_marks_current_database(self, tmp_path, monkeypatch): # Mock path resolution def mock_path(path_str): - if "rag_config_service.py" in path_str: + p = Path(path_str) + if p.name == "rag_config_service.py": return tmp_path / "chat_rag_explorer" / "rag_config_service.py" - return Path(path_str) + return p monkeypatch.setattr("chat_rag_explorer.rag_config_service.Path", mock_path)
