werkzeug.DebuggedApplication

class werkzeug.DebuggedApplication(app, evalex=False, request_key='werkzeug.request', console_path='/console', console_init_func=None, show_hidden_frames=False, lodgeit_url=None, pin_security=True, pin_logging=True)[source]

Enables debugging support for a given application:

from werkzeug.debug import DebuggedApplication
from myapp import app
app = DebuggedApplication(app, evalex=True)

The evalex keyword argument allows evaluating expressions in a traceback’s frame context.

New in version 0.9: The lodgeit_url parameter was deprecated.

Parameters:
  • app – the WSGI application to run debugged.
  • evalex – enable exception evaluation feature (interactive debugging). This requires a non-forking server.
  • request_key – The key that points to the request object in ths environment. This parameter is ignored in current versions.
  • console_path – the URL for a general purpose console.
  • console_init_func – the function that is executed before starting the general purpose console. The return value is used as initial namespace.
  • show_hidden_frames – by default hidden traceback frames are skipped. You can show them by setting this parameter to True.
  • pin_security – can be used to disable the pin based security system.
  • pin_logging – enables the logging of the pin system.
