With channels hitting 2.0 and the already large stack of moving parts surrounding Django you need some basic system administration skills and programming experience to work with the system. And there are quite a few examples to link to from the user's list that deal with those moving parts rather then Django itself. It is *not* an application that you download, install and run. An introduction "What you need to know before starting Django" would help a lot in this respect and explaining the noisiness of some logging belongs in there. Because it *is* useful if you defined that variable to True in your settings, and it's working in all projects but this one. It could be there's an extra piece of context middleware that uses the same name and deletes the variable from the context. It could be there's a Mixin missing in the view hierarchy. Or a typo you don't notice anymore after plowing through 20+ included template bits. Noisy logging is exactly what you want when debugging. It should log things that may be working as designed, especially things that are ambiguous (like undefined and false). Another thing is that logging is the ugly duckling of Django. It's not mentioned much if at all in the tutorial. It is not mentioned at all in "How to write reusable apps" and it shows in the eco system. It's like finding a diamond when an app actually has logging implemented. But it also means that novice users touching the LOGGING configuration are exceptions and I don't think Django should cater to the exceptions. -- Melvyn Sopacua -- You received this message because you are subscribed to the Google Groups "Django developers (Contributions to Django itself)" group.
