error AttributeError: 'list' object has no attribute 'abspath' : Forums : PythonAnywhere

error AttributeError: 'list' object has no attribute 'abspath'

I had a django application on my own server and I moved it to pythonanywhere. my test files say the application is running but when I try to start it from the site http://capsence.pythonanywhere.com/testbench/ I get Unhandled Exception and the error message below...

I have no clue where look for this error...

Any ideas.

That looks like there's an error in your WSGI file. Could you post it here?

OK, there's the problem:

sys.path.extend ([
    sys.path.abspath (sys.path.join (sys.path.dirname (__file__), '..')),
    sys.path.abspath (sys.path.dirname (__file__))
])

I think you mean os.path.abspath instead of sys.path.abspath.

Ok... loads of other errors... but a step further.

What are the errors you're getting now?

I think it is still related to path... it is complaining no module httpapi.urls urls is in rest http://capsence.pythonanywhere.com/rest/version/

Without looking at your files I can't be sure, but it looks like you're adding /home/capsence/capsence/metisq/httpapi to your system path and then trying to import httpapi.urls, which would look for a file /home/capsence/capsence/metisq/httpapi/httpapi/urls.py (NB httpapi is doubled), not for /home/capsence/capsence/metisq/httpapi/urls.py.

Which version of Django is your code written for, BTW?

giles | 12562 posts | PythonAnywhere staff | April 2, 2014, 3:16 p.m. | permalink

well the settings file is in /home/capsence/capsence/metisq/httpapi so I guess the error is somewhere in the settings file...

This application was started quit a number of years ago and has run on a server without any issues for years so we never updated anything... I would have to check...

Could it be to old?

deleted-user-151465 | 35 posts | April 2, 2014, 3:58 p.m. | permalink

If it's a couple of years old it's actually more likely to run :-) Right now, for Python 2.7 we support Django 1.3 (we're currently hard at work on upgrading that without breaking existing web apps that rely on the old Django version). And 1.3 is a couple of years old.

I reckon you could probably get the app one step closer to working by adding

sys.path.append('/home/capsence/capsence/metisq/)

...to your WSGI file. That would allow you to import stuff both with and without the httpapi

giles | 12562 posts | PythonAnywhere staff | April 2, 2014, 4:53 p.m. | permalink

Well that was a good start of the day... It is actually working.

Thanks
