Question

I just want to make clear that while in windows, works fine, but when I try to deploy this script in my VPS it fails.

It is kind of weird because if I add a mapping to the main web application instance which is “mainwebapp” it works, but whenever I add it to any sub application it appears as webpy “Not Found” , I am banging my head against the wall because of this.

In windows I have Wamp 2.2. in my Vps I have CentOS 5, nginx with uWsgi and same Python(2.7) & Webpy Versions from my windows.

I am almost sure that this is a problem with nginx/uwsgi because when I switch to apache/mod_wsgi in my Vps it also works as in my Wamp local server.

So far this is the code I have been testing, it is a very simple one:

class subappcls:
     def GET(self):
          return "This will also be shown fine"


sub_mappings = (
     "/subpath", subappcls
)


#subclass web app
subwebapp = web.application( sub_mappings, globals() )



#mapped clas
class mapped_cls:
def GET(self):
     return "this mapped sub app will not be found"


#Here I add mappings:
subwebapp.add_mapping("/mapped_sub_path", mapped_cls



class appcls:
def GET(self):
     return "main app"



main_mappings = (
     "/subapp", subwebapp,
     "/app", appcls
)

mainwebapp = web.application( main_mappings, fvars=globals() )

class indexcls:
def GET(self):
     return "this will be shown just fine"

mainwebapp.add_mapping("/another",indexcls)


application = mainwebapp.wsgifunc()

When I access:

/subapp/subpath #will work

/subapp/mapped_sub_path #will not work

This will work just fine:

/app

/another

This is the uwsgi log:

Thanks in advance.

The problem appears to be with reloader. The following code works if run in integrated dev server (with command python code.py):

import web


web.config.debug = False  # turns off the reloader


class subappcls:
    def GET(self):
        return "This will also be shown fine"

sub_mappings = (
    "/subpath", subappcls
)

#subclass web app
subwebapp = web.application(sub_mappings, globals())


#mapped class
class mapped_cls:
    def GET(self):
        return "this mapped sub app will not be found"


#Here I add mappings:
subwebapp.add_mapping("/mapped_sub_path", mapped_cls)


class appcls:
    def GET(self):
        return "main app"


main_mappings = (
    "/subapp", subwebapp,
    "/app", appcls,
)

mainwebapp = web.application(main_mappings, globals())


class indexcls:
    def GET(self):
        return "this will be shown just fine"

mainwebapp.add_mapping("/another", indexcls)


if __name__ == "__main__":
    mainwebapp.run()
else:
    application = mainwebapp.wsgifunc()

Running curl:

curl http://localhost:8080/subapp/mapped_sub_path
this mapped sub app will not be found
