NEW/CHANGE:

download_attachments_from_page Method in confluence.py

• Backward Compatibility: The existing usage of this method remains unchanged, and can be used as previous for downloading all attachments on page.
• New Features:
  1. Download by Filename: Added the filename parameter to enable downloading a specific file by its name. This avoids the need to process all attachments when only one file is required.
  2. In-Memory Downloads: Introduced the to_memory parameter. When set to True, files are downloaded as BytesIO objects instead of being written to disk. This is particularly useful when files are passed directly into other pipelines, such as pandas, without intermediate storage.

Example Use Case:

from atlassian import Confluence
import pandas as pd

# Initialize Confluence client
confluence = Confluence(
    url=base_url,
    token=open(token_path, 'r').read().strip(),
)

# Retrieve the page ID
page_id = confluence.get_page_id("some_space", "some_page")

# Download a specific file directly into memory
file_name = "excel_file.xlsx"
file_data = confluence.download_attachments_from_page(page_id=page_id, filename=file_name, to_memory=True)

# Process the file using pandas
excel_data = pd.read_excel(io=file_data.get(file_name))

# Output: DataFrame ready for use in further analysis
print(excel_data)

Other Changes:

• PEP-8 Compliance: Reorganized imports in confluence.py:
  • Alphabetically ordered standard library, third-party, and local imports.
