I much prefer the @render_to() syntax. This way, I can think of my view functions as "context variable creators", instead of "response returners". I think of view functions as a sort of context processor thats only meant for one specific template. Almost every single view I have ever written (more or less) follows this pattern: process stuff into variables -> add said variables to a ContextRequest -> send said ContextRequest to a template for rendering. With @render_to, it allows me to delegate all the rendering crap to the decorator, while the view function gets to focus on what is really there for; creating extra variables to be passed on to the template. It makes things simpler for me and adds readability. Also, I've never had a problem with the decorator messing up tracebacks. -- You received this message because you are subscribed to the Google Groups "Django developers" group.
