A package for handling responses with potential errors and generic data.

response_handler

A package for handling responses with potential errors and generic data.

Features

• Custom Response class for handling responses with success status, errors, and data.
• Custom Error class for defining error codes and messages.
• Custom ResponseError exception for handling response-related errors.
• Utilities for adding errors, checking success status, and retrieving error messages and codes.

Installation

You can install response_handler via pip:

pip install response_handler

Usage

Importing the Package

To use the Response class and related utilities, import them from the response_handler package:

from response_handler import Response, Error, ResponseError

Creating a Successful Response

Create a Response object with success set to True and provide any data:

response = Response(success=True, data="Some data")
if response.is_successful:
    print("Response is successful")
    print("Data:", response.data)

Creating a Failed Response

Create a Response object with success set to False:

response = Response(success=False)
if not response.is_successful:
    print("Response failed")

Adding Errors to a Response

Add errors to a response using the add_error method:

response = Response(success=False)
response.add_error(404, "Not Found")
response.add_error(500, "Internal Server Error")

if response.has_errors:
    print("Errors:")
    for code, message in zip(response.error_codes, response.error_messages):
        print(f"Error {code}: {message}")

Handling Missing Success Field

If the success field is not set, accessing is_successful raises a ResponseError:

response = Response()

try:
    print(response.is_successful)
except ResponseError as e:
    print("Caught an error:", str(e))
