CherryPy + Werkzeug Debugger?

I was comparing CherryPy and Flask when I ran into the Werkzeug Debugger, which I really like. What wonders me:

Is it possible to integrate Werkzeug's debugger into CherryPy? If so: how?

When I tried to integrate it myself, I got the console working (/console), but not the exception handler.

EDIT: Seems like CherryPy catches the errors and handles them, before Werkzeug gets them.

Solution

  • In my edit I described that CherryPy catches the errors. In the config throw_errors can be set to True. For me, setting cherrypy._cprequest.Request.throw_errors = True did this. The whole code is:

    import cherrypy
from cherrypy import wsgiserver

from werkzeug.debug import DebuggedApplication

class Root(object):

    @cherrypy.expose
    def index(self):
        return "Hello World :)"

    @cherrypy.expose
    def page(self):
        # Error:
        return self.self.self.pas

cherrypy._cprequest.Request.throw_errors = True

app = cherrypy.Application(Root(), script_name=None, config=None)
app = DebuggedApplication(app, evalex=True)

d = wsgiserver.WSGIPathInfoDispatcher({'/': app})
server = wsgiserver.CherryPyWSGIServer(('0.0.0.0', 8080), d)
try:
    server.start()
except KeyboardInterrupt:
    server.stop()

    I'm sure, there are better ways to do it, but I'm a newbie concerning CherryPy and this hack worked for me.
