Report installed dependencies and its versions when DEBUG=True

[Sebastián Magrí]

It would be useful to have a list of installed packages and its dependencies in the DEBUG output to ease the diagnose of certain errors.

Don't see much profit from this but please be more precise about the outcome:

• how this information should be printed?
• for which commands this should be printed? (shell, runserver? something else? i.e. it doesn't make much sense if user runs syncdb or dbshell commands)

It sounds more like an add-on to ​http://pythonhosted.org/django-extensions/

[Sebastián Magrí]

I'm sorry I wasn't clear enough. What I'm talking about is having the list of installed dependencies in the 500 error page template when DEBUG=True.

Best Regards.

What information do you mean when you say 'dependencies'? Do you mean all the python packages installed in your environment?

[Sebastián Magrí]

Mostly the packages installed in the current environment. INSTALLED_APPS would be used to determine which modules are currently affecting app behaviour...

[Kamu]

Would that actually help debugging? I'm skeptical it would.

[Sebastián Magrí]

I had this though after having found in several occasions that a specific error was related with the dependencies being outdated. There could be a DEBUG specific setting listing packages that need to be queried.

I don't think Django should include that feature. ​Django-debug-toolbar is much more suited for that kind of stuff and, indeed, it already contains something like that, ​Versions Panel.

I'm closing this as wontfix: it's not a job of framework to inspect other packages for versions. If you feel that this is something really needed, please bring it to DevelopersMailingList.
