Responses and Failures
Understand how to build consistent response objects and handle various types of errors, including validation and system failures, in clean architecture Python applications. Explore techniques to create response classes that support exceptions and align with HTTP error types for better error management and testing.
We'll cover the following...
There’s a wide range of errors that can occur when the use case code is executed. We discussed validation errors in the previous lesson, “Request Validation”. There are many other errors that can also occur, such as business logic errors and errors from the repository layer or other external systems that the use case interfaces with. Regardless of what error occurs, the use case should always return an object with a known structure (the response). So, we need a new object that ...
