How do I step through/debug a python web application?

I can't seem to find any information on debugging a python web application, specifically stepping through the execution of a web request.

is this just not possible? if no, why not?

Solution

  • If you put

    import pdb
pdb.set_trace()

    in your code, the web app will drop to a pdb debugger session upon executing set_trace.

    Also useful, is 

    import code
code.interact(local=locals())

    which drops you to the python interpreter. Pressing Ctrl-d resumes execution.

    Still more useful, is 

    import IPython.Shell 
ipshell = IPython.Shell.IPShellEmbed()
ipshell(local_ns=locals())

    which drops you into an IPython session (assuming you've installed IPython). Here too, pressing Ctrl-d resumes execution.
