Re: Django environment setup path problem

[Bill Freeman]

How are you invoking manage.py?  Try cd'ing to the directory containing it before running it and see if that helps.  (That directory will then automatically be on python's sys.path, which is needed.  DJANGO_SETTINGS_MODULE must be a python style package.module style path, not a filesystem path, so depending on what yout mean by "path to project" I wouldn't expect your second approach to work either.)

I see what you're doing, (It did take me half an hour of staring at your
email though)

The steps are:
$django-admin startproject myproj
$cd myproj
$vi myproj/settings.py
than add your databases
than run
$./manage.py syncdb
not django-admin syncdb

This is a version 1.4 Django.  Yes?

Try adding to manage.py, between the "if ..." line and the "os.environ..." lines, and indented like the "os.environ..." line:

    import pdb;pdb.set_trace()

Then run:

   $ ./manage.py shell

When it stops at the breakpoint, type:

  p os.environ['DJANGO_SETTINGS_MODULE']

I expect this to complain that there is no such key.  Now type:

  n

to single step over the setdefault line and again type:

  p os.environ['DJANGO_SETTINGS_MODULE']

This time it should be happy and print something like:

  "firstdjango.settings"

Now try typeing (be sure to include the "!"):

  !import firstdjango.settings as s

and if that doesn't raise an error, try:

  pp s.INSTALLED_APPS

If this stuff isn't working do:

  p os.getcwd()
  pp sys.path

Assuming that the current working directory is the one containing manage.py and the like named directory that in turn contains settings.py, then either it must be on sys.path, or an empty string (more likely) will be on sys.path (implying the use of the current working directory).

If everything so far was good, and nobody has a better suggestion, and you want to take the time, then you can use the "m" command again to step over the "from ... import ..." line, and then the "s" command to step into the "execute_from_command_line" function, use "n" to step through it's parts until you find the one that fails, exit, restart, step back to the failing part and step into it, repeat until enlightened.
