Hello Gabriel,
Thanks for support.
repr works as you say and I had some complaints, it wont format the output.
Finding some string in 100 key dictionary in formatted in single line bit
problematic. Is it any way to format it ?
Also, very interesting things are happen.
def debug(self):
r = '<pre>'
r += repr(self.data)
r += '</pre>'
return r
following code works and does not work ever reload ?
One time work another reload wont work. What I missing ?
And is possible to get this ? (I store the environ here)
r += repr(self.data['environ']['mod_wsgi.listener_port'])
or similar multi sub level elements ?
Regards...
