function get_default_schema_file_v1

Maturity: 35

Returns the absolute file path to the default database schema JSON file (Poulpharm_labosoft.json) located in the same directory as the function's module.

/tf/active/vicechatdev/smartstat/sql_query_generator.py
Lines:
522 - 525
Complexity:
simple

Purpose

This utility function provides a consistent way to locate the default database schema file for the Poulpharm_labosoft system. It constructs an absolute path by combining the directory of the current module with the schema filename, ensuring the schema file can be reliably found regardless of the current working directory. This is commonly used for initializing database connections or validating database structures.

Source Code

def get_default_schema_file() -> str:
    """Get default database schema file path"""
    import os
    return os.path.join(os.path.dirname(__file__), 'Poulpharm_labosoft.json')

Return Value

Type: str

Returns a string containing the absolute file path to 'Poulpharm_labosoft.json'. The path is constructed using os.path.join() with the directory of the current module file (__file__) and the schema filename. Example return value: '/path/to/module/directory/Poulpharm_labosoft.json'

Required Imports

import os

Usage Example

# Assuming the function is in a module named 'database_utils'
from database_utils import get_default_schema_file

# Get the schema file path
schema_path = get_default_schema_file()
print(f"Schema file located at: {schema_path}")

# Typical usage: loading the schema
import json
with open(schema_path, 'r') as f:
    schema = json.load(f)
    print(f"Loaded schema with {len(schema)} entries")

Best Practices

  • Always check if the returned file path exists before attempting to open it using os.path.exists() or Path.exists()
  • Use this function instead of hardcoding the schema file path to ensure portability across different environments
  • Consider wrapping file operations in try-except blocks to handle cases where the schema file might be missing or inaccessible
  • The function uses __file__ which may not work correctly in certain execution contexts (e.g., frozen executables, some REPL environments)
  • For production use, consider adding validation to ensure the returned path points to a valid, readable JSON file
