Mezzanine4 config wsgi file : Forums : PythonAnywhere

Mezzanine4 config wsgi file

Hi, Yesterday I installed Mezzanine-4.0.0 and I have a silly issue when I config the wsgi file in the tab "web" tha application isn't working, this is the message: ImportError: No module named 'FEBA2.settings'

I think due to the new mezzanine creates a folder inside the main folder of the project and creates an application (django style), but I don't know how config wsgi to define this new folder.

this is wsgi working with mezzanine-3.10.1 and isn't with mezzanine-4 I have tested some variances and all failed.

import os
import sys

# add project folder and its parent folder to path. mezzanine needs both.
for path in ['/home/mateuo/', '/home/mateuo/FEBA']:
    if path not in sys.path:
        sys.path.append(path)

# specify django settings
os.environ['DJANGO_SETTINGS_MODULE'] = 'FEBA.settings'

# load default django wsgi app
import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()

Thank you in advance

do you have two projects, one called FEBA and one called FEBA2?

Hi Conrad,

Thank you for your reply. Yes I have two projects one called FEBA and the other FEBA2.

oh I took a look at your wsgi files. Double check the difference between your FEBA wsgi and your FEBA2 wsgi. Your FEBA2 one has a different path.

Thank you Conrad for your reply, this is checked and I proved this differences with the path and still not working

first try: for path in ['/home/mateuo/', '/home/mateuo/FEBA2']:
second try: for path in ['/home/mateuo/FEBA2/','/home/mateuo/FEBA2/FEBA2']:
'this is the FEBA2 wsgi file'
import os
import sys

# add project folder and its parent folder to path. mezzanine needs both.
for path in ['/home/mateuo/', '/home/mateuo/FEBA2']:
    if path not in sys.path:
        sys.path.append(path)

# specify django settings
os.environ['DJANGO_SETTINGS_MODULE'] = 'FEBA2.settings'

# load default django wsgi app
import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()

That's really strange. Are you able to import your settings file straight into Python?

Yes indeed, Glenn. I begin to be a bit worried... I have made some tests and I have deleted some times the application and I have change the name. These are the actual names:

the mezzanine project is called ebonnin the tree is /home/mateuo/ebonnin and the settings are in /home/mateuo/ebonnin/ebonnin/settings.py

I can import the settings directly in a console with a shell "python manage.py shell" in the folder of the mezzanine project. this is the result:

(feba3_virtualenv)15:20 ~/ebonnin $ python manage.py shell

Ah! I think I've got it. The problem is that you have /home/mateuo/ on the path and that has a module in it (/home/mateuo/ebonnin) and THAT has no settings.py so Python thinks it can't find settings because there isn't one in the first ebonnin module that it finds.

Oh! right I think that's it as well , but how can I adapt the wsgy.py? I've tried some possibilities but don't work, can you help me, or give me some idea?

Thank you in advance

Work out why mezzanine needs your home directory on the path. That seems like something strange is going on. Then remove your home directory from the path.

glenn | 9498 posts | PythonAnywhere staff | July 15, 2015, 5:12 p.m. | permalink

Thank you Glenn, only remove the home directory will be enought? I will test it and I will post it.

Thank you

Hi Glenn,

Removing the home directory isn't working.

I'm running out of ideas...

Thank you for your help

Hmm. Your web app runs with the current working directory set to your home directory, and it's possible that "." is on the Python path. Try adding this to the path setup in your WSGI file:

while "." in sys.path:
    sys.path.remove(".")

(The while loop is just in case "." is on the path multiple times.)

If that doesn't work, try adding a print "Python path is", sys.path to your WSGI file somewhere near the top, then take a look at the server log and see what it prints there -- if you post it here, it might give us some clues...

Hi Giles, This is the wsgi script with the prints and your modification:

import os
import sys
print ("Python path is at top", sys.path)
# add project folder and its parent folder to path. mezzanine needs both.
for path in ['/home/mateuo/','/home/mateuo/ebonnin/']:
    if path not in sys.path:
        sys.path.append(path)
while "." in sys.path:
    sys.path.remove(".")

# specify django settings
os.environ['DJANGO_SETTINGS_MODULE'] = 'ebonnin.settings'
print ("Python path is at the end", sys.path)
# load default django wsgi app
import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()

Thank you for your reply, this isn't working . This is the python path at the beginning and at the end of the wsgy script:

Python path is at top ['/var/www', '.', '', '/var/www', '/home/mateuo/.virtualenvs/feba3_virtualenv/lib/python3.4', '/home/mateuo/.virtualenvs/feba3_virtualenv/lib/python3.4/plat-x86_64-linux-gnu', '/home/mateuo/.virtualenvs/feba3_virtualenv/lib/python3.4/lib-dynload', '/usr/lib/python3.4', '/usr/lib/python3.4/plat-x86_64-linux-gnu', '/home/mateuo/.virtualenvs/feba3_virtualenv/lib/python3.4/site-packages']

Python path is at the end ['/var/www', '', '/var/www', '/home/mateuo/.virtualenvs/feba3_virtualenv/lib/python3.4', '/home/mateuo/.virtualenvs/feba3_virtualenv/lib/python3.4/plat-x86_64-linux-gnu', '/home/mateuo/.virtualenvs/feba3_virtualenv/lib/python3.4/lib-dynload', '/usr/lib/python3.4', '/usr/lib/python3.4/plat-x86_64-linux-gnu', '/home/mateuo/.virtualenvs/feba3_virtualenv/lib/python3.4/site-packages', '/home/mateuo/', '/home/mateuo/ebonnin/']

Have you see any clue? Thanks in advance

I think the problem is that now you're adding the home directory again. If you want this to work, it's essential that neither "/home/mateuo/" nor "." is on the path.

giles | 11788 posts | PythonAnywhere staff | July 16, 2015, 2:59 p.m. | permalink

Sorry, I have test it again without home directory and It doesn't work :( this is the wsgi file:

import os
import sys
print ("Python path is at top", sys.path)
# add project folder and its parent folder to path. mezzanine needs both.
for path in ['/home/mateuo/ebonnin/']:
    if path not in sys.path:
        sys.path.append(path)
while "." in sys.path:
    sys.path.remove(".")

# specify django settings
os.environ['DJANGO_SETTINGS_MODULE'] = 'ebonnin.settings'
print ("Python path is at the end", sys.path)
# load default django wsgi app
import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()

and this is the server.log

2015-07-16 15:13:44 Python path is at top ['/var/www', '.', '', '/var/www', '/home/mateuo/.virtualenvs/feba3_virtualenv/lib/python3.4', '/home/mateuo/.virtualenvs/feba3_virtualenv/lib/python3.4/plat-x86_64-linux-gnu', '/home/mateuo/.virtualenvs/feba3_virtualenv/lib/python3.4/lib-dynload', '/usr/lib/python3.4', '/usr/lib/python3.4/plat-x86_64-linux-gnu', '/home/mateuo/.virtualenvs/feba3_virtualenv/lib/python3.4/site-packages']
2015-07-16 15:13:44 Python path is at the end ['/var/www', '', '/var/www', '/home/mateuo/.virtualenvs/feba3_virtualenv/lib/python3.4', '/home/mateuo/.virtualenvs/feba3_virtualenv/lib/python3.4/plat-x86_64-linux-gnu', '/home/mateuo/.virtualenvs/feba3_virtualenv/lib/python3.4/lib-dynload', '/usr/lib/python3.4', '/usr/lib/python3.4/plat-x86_64-linux-gnu', '/home/mateuo/.virtualenvs/feba3_virtualenv/lib/python3.4/site-packages', '/home/mateuo/ebonnin/']

Thank you for all your help I hope you can figure it out.

This is very strange! The empty string in the path looks odd. Let's trying code like this to remove it, just after the code that removes ".":

while "" in sys.path:
    sys.path.remove("")

giles | 11788 posts | PythonAnywhere staff | July 16, 2015, 3:37 p.m. | permalink

Not working :( , but a new error :) django.core.exceptions.AppRegistryNotReady: Models aren't loaded yet. at the end the error.log

this is how looks the wsgi:

import os

print ("Python path is at top", sys.path)
# add project folder and its parent folder to path. mezzanine needs both.
for path in ['/home/mateuo/ebonnin/']:
    if path not in sys.path:
        sys.path.append(path)
while "." in sys.path:
    sys.path.remove(".")
while "" in sys.path:
    sys.path.remove("")

# specify django settings
os.environ['DJANGO_SETTINGS_MODULE'] = 'ebonnin.settings'
print ("Python path is at the end", sys.path)
# load default django wsgi app
import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()

Well, that's some kind of progress at least :-)

That error often means that there's a mismatch between the code you're using in the WSGI file to load Django and the version of Django you're using. If you're using Django >= 1.6, then you need to use this code to load it:

from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()

...and not the old-style code:

import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()

Just wanna say thanks. This fixed my problem. Weird, undocumented from Mezzanine to have the main project folder as an app. Removing "." and "" from the path did the trick.

Same here, totally baffled by this error when I switched to Mezzanine 4, this post solved it for me. Thanks!
