Table of Contents

This script automatically adds monthly expense entries to a ledger table. It checks whether entries for the current month already exist and only creates new ones if needed. It also creates missing select options automatically.

  1. The script calculates the first day of the current month
  2. It checks if entries for “Office supplies” and “Software licenses” already exist
  3. If a select option doesn’t exist yet, it creates it
  4. Only then does it add the new row

    {"Category": "Software licenses", "Description": "Monthly software licenses", "Amount": 500.00, "Type": "Expense"},
]

for entry in ENTRIES:
    rows = base.query(f"SELECT _id FROM `{TABLE_NAME}` WHERE `Month` = '{first_of_this_month}' AND `Category` = '{entry['Category']}'")

        entry['Month'] = first_of_this_month
        base.append_row(TABLE_NAME, entry)
        print(f"Added: {entry['Category']}")

        print(f"Skipped (already exists): {entry['Category']}")
