Walkthrough

The changes involve updates to the process_queue.py file, introducing a new function called vectorize_extraction_process_step for handling the vectorization of extraction results and storing them in a database. The process_step_task function is modified to retrieve necessary identifiers and call the new vectorization function, with enhanced error handling for exceptions. Additionally, the test suite in test_process_queue.py is updated with new test cases to validate the functionality of the new vectorization method under various scenarios. Modifications are also made to the chat.py file for document extraction and processing, along with configuration updates in config.py.

Changes

File Change Summary
backend/app/processing/process_queue.py - Added method: vectorize_extraction_process_step for vectorizing extraction results and storing in ChromaDB.
- Updated process_step_task to include project ID and filename retrieval, and to call the new vectorization function with error handling enhancements.
backend/tests/processing/test_process_queue.py - Added new tests for vectorize_extraction_process_step covering single reference, multiple references, and empty sources.
- Updated imports to include MagicMock.
backend/app/api/v1/chat.py - Enhanced chat function to create a new ChromaDB instance for extracting reference documents and processing them based on user queries.
backend/app/config.py - Added new attributes: chat_extraction_doc_threshold (float) and chat_extraction_max_docs (int) to the Settings class.

Poem

🐇 In the queue where processes flow,
A new step added, watch it grow!
Vectorize with care, store it right,
In ChromaDB, shining bright.
With tests in place, all is well,
In the rabbit's world, we surely excel! 🥕

Chat

There are 3 ways to chat with CodeRabbit:

  • Review comments: Directly reply to a review comment made by CodeRabbit. Example:
    • I pushed a fix in commit <commit_id>, please review it.
    • Generate unit testing code for this file.
    • Open a follow-up GitHub issue for this discussion.
  • Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
    • @coderabbitai generate unit testing code for this file.
    • @coderabbitai modularize this function.
  • PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
    • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
    • @coderabbitai read src/utils.ts and generate unit testing code.
    • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
    • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

185-220: Consider adding edge case assertions.

The test effectively verifies the basic functionality of vectorizing a single reference. However, consider adding assertions for:

  • Special characters in the filename or sources
  • Very long source strings
  • Unicode characters

267-267: Remove the placeholder comment.

The comment # Replace with the correct module path appears to be a leftover development note and should be removed.


268-287: Consider additional empty/null scenarios.

While the test correctly verifies empty sources handling, consider adding test cases for:

  • null sources
  • Empty reference name
  • Empty references array
  • null references
backend/app/processing/process_queue.py (1)

375-375: Specify a more precise type annotation for references parameter

The references parameter is annotated as dict, but it appears to be a list of lists containing dictionaries. Providing a more specific type annotation improves code readability and can help with type checking tools.

Suggested change:

 def vectorize_extraction_process_step(project_id: int, process_step_id: int, filename: str, references: List[List[Dict[str, Any]]]) -> None:
+    from typing import List, Dict, Any

3-3: LGTM! Import changes are appropriate.

The addition of MagicMock and vectorize_extraction_process_step imports aligns with the new test requirements.

Also applies to: 9-10


221-265: LGTM! Comprehensive test for multiple references.

The test effectively verifies:

  • Multiple references for the same field
  • Multiple fields
  • Correct concatenation of sources
  • Proper metadata structure

29-31: Add documentation for the new configuration parameters.

Please add docstrings to explain:

  • The purpose of chat_extraction_doc_threshold and what the 0.5 threshold represents
  • The significance of chat_extraction_max_docs and its impact on performance/memory
     # Extraction References for chat
-    chat_extraction_doc_threshold: float = 0.5
-    chat_extraction_max_docs: int = 50
+    # Minimum similarity score (0-1) required for documents to be considered relevant
+    chat_extraction_doc_threshold: float = 0.5
+    # Maximum number of documents to retrieve during chat extraction
+    chat_extraction_max_docs: int = 50

88-96: Improve error message clarity in vectorization error handling.

The error handling for vectorization is well-implemented and isolated from the main process flow. However, the error message could be more specific.

Consider this improvement:

- logger.error(f"Failed to vectorize extraction results for chat {traceback.format_exc()}")
+ logger.error(f"Failed to vectorize extraction results for project {project_id}, process step {process_step_id}: {traceback.format_exc()}")

375-375: Add type hints and docstring for better code documentation.

The function signature could be improved with proper type hints and documentation.

Consider this improvement:

-def vectorize_extraction_process_step(project_id: int, process_step_id: int, filename: str, references: dict) -> None:
+def vectorize_extraction_process_step(
+    project_id: int,
+    process_step_id: int,
+    filename: str,
+    references: List[List[Dict[str, Any]]]
+) -> None:
+    """Vectorize extraction results and store them in the database.
+
+    Args:
+        project_id: The ID of the project
+        process_step_id: The ID of the process step
+        filename: The name of the processed file
+        references: List of extraction references containing sources to vectorize
+
+    Returns:
+        None
+    """

397-409: ⚠️ Potential issue

Fix mismatched content between docs and metadata.

The documents being stored don't contain the actual content from field_references, making the vectorization ineffective.

Apply this fix:

-    docs = [f"{filename} {key}" for key in field_references]
+    docs = list(field_references.values())
     metadatas = [
         {
             "project_id": project_id,
             "process_step_id": process_step_id,
             "filename": filename,
-            "reference": reference
+            "field_name": key
         }
-        for reference in field_references.values()
+        for key in field_references.keys()
     ]
