“AttributeError: ‘module’ object has no attribute ‘blah’”

  • The obvious cause of this is that the settings.py doesn’t have the directory containing blah listed in INSTALLED_APPS.
  • A less obvious cause: you’ll also get this error if the directory doesn’t contain a file __init__.py.

    Thanks! I would have never guessed that from the stack trace.

    I’m just having the same error, and either of those do not apply. I have the app listed in INSTALLED_APPS, and I have the __init__.py.

    Yes, that was mine :( __init__.py

    Thx to google and you!

    In my case the reason was dirt .pyc files hanging around. I cleaned all pyc files and it worked

    Thanks so much! __init__.py was my problem :)

    just a brief note

    if you use import to include a module, make sure you don’t have a file named just the same as the module you are trying to include in current directory

    it seems that python takes preference for local files over modules thus import fails

    a rookie observation

    cheers

    Thanks for the hint. In my case the script was named “Cookie”, the same as the module imported. One symptom was that I was getting double printing in both Terminal and browser.

    thanks. my problem was that i had two versions of a python package (numpy). i was trying to invoke a method that was only in the new one, however it found the old package first, so it couldn’t locate the new method.

    anyway, your post got me looking in the right direction :)
