I have tried implementing routes_onerror in routes.py like this:
routes_onerror = [
(r'welcome/500', r'/welcome/default/on500'),
(r'welcome/400', r'/welcome/default/on400')
]
and added these functions in default.py controller:
def raise500():
raise ValueError('random internal error')
def raise400():
print "in raise 400"
raise HTTP(400, 'not the droids')
def on500():
print "alternate handler for 500"
return "something useful, maybe ticket number encoded in json?"
def on400():
print "in on 400"
return "handler for 400s"
def myform():
form = FORM('blah', INPUT(_name='name'),
INPUT(_type='submit'), _action=URL('raise400'))
return response.render({'form': form})
If I visit the "raise" urls from a browser everything works as expected
(although I thought I'd see redirects in DevTools:network and I'm not
seeing that, just immediate responses). Even the response status is correct.
But if I post from a form (or use python requests lib) then the response is
status 500 and response text = "Server Error"
Also I get this traceback from the console running the web2py server:
ERROR:Rocket.Errors.Thread-2:Traceback (most recent call last):
File "D:\web2py\gluon\rocket.py", line 1337, in run
self.run_app(conn)

return wsgibase(new_environ, responder)
File "D:\web2py\gluon\main.py", line 534, in wsgibase
if request.body:
File "D:\web2py\gluon\globals.py", line 281, in body
raise HTTP(400, "Bad Request - HTTP body is incomplete")
HTTP: 400 BAD REQUEST
Am I doing something wrong or is routes on error not supposed to handle
POST?
