SmarterNeverCachedWebView

class smarter.lib.django.views.SmarterNeverCachedWebView(**kwargs)[source]

Bases: SmarterWebHtmlView

An optimized web view that requires authentication and is never cached.

This class combines two critical behaviors for secure and dynamic web applications:

  1. Authentication Enforcement: Inherits from SmarterAuthenticatedWebView, which applies the @login_required decorator to the dispatch method. This ensures that only authenticated users can access the view. If an unauthenticated user attempts access, they are redirected to the login page, and the cache is expired to prevent sensitive data leakage.

  2. Cache Prevention: Uses the @never_cache decorator (applied via method_decorator to the dispatch method). This instructs Django and downstream proxies/browsers to never cache responses from this view. This is essential for views that display user-specific or sensitive information, ensuring that no part of the response is stored or reused.

By combining these decorators, SmarterAuthenticatedNeverCachedWebView guarantees that: - Only logged-in users can access the view. - Every response is generated fresh for each request, with no caching at any layer.

This makes it ideal for pages displaying private, frequently changing, or security-sensitive data.
