Better exceptions

[igorbenav]

Exception handling was restructured.

Old exceptions structure:

├── app                          # Main application directory.
   ├── ...
   │
   ├── api                       # Folder containing API-related logic.
   │   ├── ...
   │   ├── exceptions.py         # Custom exceptions for the API.
   │
   ├── core                      # Core utilities and configurations for the application.
   │   ├── ...
   │   │
   │   ├── exceptions            # Custom exception classes.
   │   │   ├── __init__.py
   │   │   └── exceptions.py     # Definitions of custom exceptions.

New structure:

├── app                              # Main application directory.
   ├── ...
   │
   ├── core                          # Core utilities and configurations for the application.
   │   ├── ...
   │   │
   │   ├── exceptions                # Custom exception classes.
   │   │   ├── __init__.py
   │   │   ├── cache_exceptions.py   # Exceptions related to cache operations.
   │   │   └── http_exceptions.py    # HTTP-related exceptions.

Now to use http exceptions you may just import from app/core/exceptions/http_exceptions and optionally add a detail:

from app.core.exceptions.http_exceptions import NotFoundException

# If you want to specify the detail, just add the message
if not user:
  raise NotFoundException("User not found")

# Or you may just use the default message
if not post:
  raise NotFoundException()

The predefined possibilities in http_exceptions are the following:

• CustomException: 500 internal error
• BadRequestException: 400 bad request
• NotFoundException: 404 not found
• ForbiddenException: 403 forbidden
• UnauthorizedException: 401 unauthorized
• UnprocessableEntityException: 422 unprocessable entity
• DuplicateValueException: 422 unprocessable entity
• RateLimitException: 429 too many requests
