Patrick Kennedy: Application and Request Contexts in Flask

I wrote two blog posts on TestDriven.io about how the Application and Request contexts are handled in Flask:

1. Basics: Understanding the Application and Request Contexts in Flask
2. Advanced: Deep Dive into Flask’s Application and Request Contexts

The first blog post provides examples of how to the Application and Request contexts work, including how the current_app, request, test_client, and test_request_context can be used to effectively used to avoid pitfalls with these contexts.

The second blog post provides a series of diagrams illustrating how the Application and Request contexts are processed when a request is handled in Flask. This post also dives into how LocalStack objects work, which are the objects used for the Application Context Stack and the Request Context Stack.
