Since I'm not strictly python developer please don't flame me just for the question. I'm wondering about Python 3k, that from my point of view, might be some kind of misconception. Or quite in-relevant step forward (I'm taking into account the 2.6 and 3k releases, which was almost one after another). Before the flame will start, I'll ex...
I have some custom logic that needs to be executed every single time a URL is reversed, even for third-party apps. My project is a multitenant web app, and the tenant is identified based on the URL. There isn't a single valid URL that doesn't include a tenant identifier. I already have a wrapper function around reverse, but now I need a...
