backend/app/utils.py (1)

32-39: LGTM: New clean_text function added with room for enhancements.

The clean_text function effectively removes newlines and punctuation from the input text. However, consider the following suggestions for potential improvements:

  1. Handle multiple consecutive spaces that might result from newline removal.
  2. Add an option to preserve certain punctuation marks if needed in some use cases.
  3. Consider handling other whitespace characters like tabs.

Example implementation incorporating these suggestions:

def clean_text(text, preserve_punctuation=None):
    # Remove newline and tab characters
    text = re.sub(r'[\n\t]+', ' ', text)
    
    # Remove multiple spaces
    text = re.sub(r'\s+', ' ', text)

    # Remove punctuation, optionally preserving specified characters
    if preserve_punctuation:
        punct_to_remove = ''.join(c for c in string.punctuation if c not in preserve_punctuation)
    else:
        punct_to_remove = string.punctuation
    
    text = text.translate(str.maketrans("", "", punct_to_remove))

    return text.strip()

This implementation uses regex for more comprehensive whitespace handling and adds an optional parameter to preserve specific punctuation if needed.

120-120: LGTM: Consistent use of asset_id in segmentation submission

The change from asset_content.id to asset_content.asset_id is correct and consistent with the updates in the process_segmentation function. This ensures that the proper identifier is passed to the segmentation process.

For even better clarity, consider renaming the asset_content variable to simply asset since we're now using asset_id. This would make the line read:

asset.asset_id,

This change would make it clearer that we're dealing with the asset's ID rather than potentially confusing it with the content's ID.

backend/app/api/v1/projects.py (5)

72-75: Approve formatting change and suggest error message improvement

The reformatting of the HTTPException improves readability. However, consider enhancing the error message to provide more specific information:

raise HTTPException(
    status_code=500,
    detail=f"An error occurred while retrieving projects: {str(e)}. Please try again later.",
)

This change would help with debugging by including the specific error message in the response.


102-105: Approve formatting change and suggest error message improvement

The reformatting of the HTTPException improves readability. However, consider enhancing the error message to provide more specific information:

raise HTTPException(
    status_code=500,
    detail=f"An error occurred while retrieving the project: {str(e)}. Please try again later.",
)

This change would help with debugging by including the specific error message in the response.


140-143: Approve formatting change and suggest error message improvement

The reformatting of the HTTPException improves readability. However, consider enhancing the error message to provide more specific information:

raise HTTPException(
    status_code=500,
    detail=f"An error occurred while retrieving assets: {str(e)}. Please try again later.",
)

This change would help with debugging by including the specific error message in the response.


357-359: Approve formatting changes and suggest error message improvement

The reformatting of the HTTPExceptions improves readability. The 404 error message is appropriate and specific. However, consider enhancing the 500 error message to provide more specific information:

raise HTTPException(
    status_code=500,
    detail=f"An error occurred while updating the project: {str(e)}. Please try again later.",
)

This change would help with debugging by including the specific error message in the response.

Also applies to: 372-375


383-385: Approve formatting changes and suggest error message improvement

The reformatting of the HTTPExceptions improves readability. The 404 error message is appropriate and specific. However, consider enhancing the 500 error message to provide more specific information:

raise HTTPException(
    status_code=500,

Line range hint 205-218: Fix indentation of return wrapper in handle_exceptions decorator

The return wrapper statement on line 218 is incorrectly indented inside the wrapper function. It should be dedented to correctly return the wrapper function from handle_exceptions.

Apply this diff to fix the indentation:

 def handle_exceptions(func):
     @wraps(func)
     def wrapper(*args, **kwargs):
         try:
             return func(*args, **kwargs)
         except CreditLimitExceededException:
             logger.error("Credit limit exceeded")
             raise
         except Exception as e:
             logger.error(f"Error in {func.__name__}: {str(e)}")
             logger.error(traceback.format_exc())
             raise
-        return wrapper
+    return wrapper

Line range hint 221-252: Redundant exception handling inside extractive_summary_process

The extractive_summary_process function is decorated with @handle_exceptions, which already handles exceptions and logs errors. The internal try-except block inside this function may be redundant unless it's intended to return default values on exceptions instead of raising them. This could lead to inconsistencies in error handling.

Consider removing the internal try-except block to rely on the decorator for exception handling, or clarify the intended behavior if the function should return default values on exceptions.


Line range hint 276-296: Ensure pdf_content is correctly populated

The pdf_content variable is initialized to an empty string and may remain empty if the conditions are not met, potentially leading to issues when passed to the extract_data function.

Ensure that pdf_content is assigned a valid value or handle the case when it is empty:

 if not pdf_content:
     pdf_content = (
         "\n".join(asset_content.content["content"])
         if asset_content.content
         else None
     )
+if not pdf_content:
+    logger.error("PDF content is empty. Verify asset content and process details.")
+    # Handle the empty content case appropriately

Line range hint 276-296: Add @handle_exceptions decorator to extract_process

The extract_process function is not decorated with @handle_exceptions, unlike extractive_summary_process. For consistency and to ensure exceptions are properly handled and logged, consider adding the decorator.

Apply this diff to add the decorator:

+@handle_exceptions
 def extract_process(api_key, process, process_step, asset_content):
     pdf_content = ""

6-6: LGTM: Appropriate import added for text processing.

The addition of the string module import is correct and necessary for the new clean_text function. It's properly placed with other imports at the top of the file.


Line range hint 1-41: Overall: Positive addition to the utils module.

The changes in this file enhance the functionality of the utils module by adding a text cleaning capability. The new clean_text function and its associated import are well-integrated into the existing file structure without affecting other functions. This addition could be beneficial in various parts of the project where text preprocessing is required.

To ensure the new function is used effectively:

  1. Consider adding unit tests for the clean_text function to verify its behavior with different input types.
  2. Update the module's documentation (if it exists) to include information about the new function.
  3. Review other parts of the project where this text cleaning functionality could be useful and consider implementing it there.

To verify the potential usage of this new function, we can search for patterns in the codebase where text cleaning might be beneficial:

This will help identify areas where the new clean_text function could be applied to improve text processing throughout the project.

✅ Verification successful

Integrate clean_text Function in Identified Locations

Replace the existing text processing in backend/app/utils.py with the new clean_text function:

  • Before:

    text = text.replace("\n", " ")
    text = text.translate(str.maketrans("", "", string.punctuation))
  • After:

    text = clean_text(text)

This change eliminates redundant code and centralizes text cleaning logic, improving maintainability.

🏁 Scripts executed

The following scripts were executed for the analysis:

Script:

#!/bin/bash
# Search for potential use cases of the clean_text function
echo "Potential use cases for clean_text function:"
rg -i "text\s*=|text\.strip|text\.replace" --type py

25-25: LGTM: Function signature update improves clarity

The change from asset_content_id to asset_id in the function signature is a good improvement. It more accurately represents the parameter's purpose and aligns with the rest of the codebase.


55-55: LGTM: Consistent error logging

The error logging message has been correctly updated to use asset_id instead of asset_content_id. This change maintains consistency with the other updates in the file and ensures that error messages accurately reflect the current parameter naming.


Line range hint 25-120: Summary: Consistent renaming improves clarity, verify impact on other modules

The changes in this file consistently rename asset_content_id to asset_id, which improves clarity and aligns with the intended use of the asset identifier. While these changes look good within this file, it's important to ensure that this renaming doesn't negatively impact other parts of the system that might expect asset_content_id.

To ensure that this change doesn't introduce inconsistencies in other parts of the codebase, please run the following verification:

#!/bin/bash
# Search for any remaining instances of 'asset_content_id' in Python files
# This will help identify any places where the old naming is still in use
rg -t py 'asset_content_id' .

# Search for uses of 'asset_id' to ensure it's being used correctly
rg -t py 'asset_id' .

Review the results to ensure that:

  1. There are no unexpected occurrences of asset_content_id.
  2. All uses of asset_id are correct and consistent with this change.

28-28: LGTM: Consistent parameter usage throughout the function

The changes from asset_content_id to asset_id are consistently applied throughout the process_segmentation function. This maintains the logical integrity of the function while improving clarity.

To ensure complete consistency, let's verify that no instances of asset_content_id remain in this file:

Also applies to: 39-39, 50-50, 59-59

✅ Verification successful

LGTM: asset_content_id successfully replaced with asset_id in file_preprocessing.py

All instances of asset_content_id have been fully replaced with asset_id in file_preprocessing.py, ensuring consistency within the function and enhancing code clarity.

🏁 Scripts executed

The following scripts were executed for the analysis:

Script:

#!/bin/bash

452-455: Approve logging format change

The reformatting of the logging statement improves readability while maintaining appropriate and specific information about the deleted asset. This change is good and doesn't require further modifications.


438-438: Approve addition of project_id to asset_info

The addition of project_id to the asset_info dictionary is a good improvement. It provides more context about the asset being deleted, which can be valuable for logging, debugging, or potential future use cases where project association needs to be tracked.


451-451: Approve addition of empty line for improved readability

The addition of an empty line after the soft deletion of the asset improves code readability by clearly separating the deletion logic from the subsequent logging statement. This change enhances the overall structure and readability of the function without affecting its behavior.
