Web2py admin page causing internal error (version 2.9.10)

[Mark Li]

I just upgraded my web2py version on Pythonanywhere from 2.7.4 to 2.9.10, so my live site can match my test site web2py version

This in turn has caused the admin page to start producing errors, so I am unable to look at error tickets (they will just produce more errors).

I'm quite lost as to what I can do to fix this problem, as I can't even read the error tickets (it's just a continuing cycle of internal errors).

You probably need to clear old sessions and old tickets out (back up the tickets, then clear the directory).  As I remember it, old sessions and old tickets were the two biggest sources of error loops.

I've run sessions2trash.py to remove all sessions, as well as remove all the files from the errors folder. Unfortunately I'm still getting the error loop. Should I do this for the admin app as well?

I am looking at the errors for the admin (at the files), and I am getting a "<type 'exceptions.NameError'> name 'DEMO_MODE' is not defined"" error

That doesn't ring any bells for me, although I'm currently on 2.11.2.  I think the step that required some extra effort for pydal 2.10.x.

Did you update the admin app?

Also, if I remember there have been many correction over 2.10.x web2py build... I would avoid the 2.10.x series for this reason... I remember having testing and having found it not that stable and I stay with 2.9.5...

2.11.2 seems to work great...

Why not 2.9.12...

Why not install 2.11.2??

I've updated to version 2.11.2, and the problem still persists. I've deleted all errors, cache, and sessions for both admin app and "myapp"

I am getting the following traceback when I look in the admin/errors files:

Traceback (most recent call last):
  File "/home/marladarla7/web2py/

gluon/restricted.py", line 224, in restricted
    exec ccode in environment
  File "applications/admin/models/0_imports.py", line 15, in <module>
    from mercurial import ui, hg, cmdutil
  File "/home/marladarla7/web2py/gluon/custom_import.py", line 71, in custom_importer
    return NATIVE_IMPORTER(oname, globals, locals, fromlist, level)
  File "mercurial.py", line 3, in <module>
    if DEMO_MODE or MULTI_USER_MODE:
NameError: name 'DEMO_MODE' is not defined

I have checked 0.py model, and DEMO_MODE = False, so I have no idea why I am getting this error

Deleting all the .pyc files from the web2py directory seems to have done the trick.

Don't forget to update the web2py file in your app...

Backup your app before :)

I did miss this, I keep skipping over this part!

[Richard Vézina]

You mean you don't do it and your app still works? Or you are not there yet...

Hope it works for you...

[Mark Li]

I didn't update the extra files from web2py (like appadmin.py) into my app folder, but it still worked. I've updated the files now as well though.

[Richard Vézina]

If you have not customized them it is a not brainer and you are much more confident that your app is working properly with the new web2py version...

The only thing is that the new welcome is BS3 based, so you may take care if you are not ready for it...
