Package importing problem

[=?iso-8859-9?Q?Tongu=E7?= Yumruk]

Hi,

I'm writing a plugin based application with python 2.1 but I really have
some trouble with creating a package. My directory structure is:


Skib/Server/Python/:
skib
skibserver

Skib/Server/Python/skib:
__init__.py
PluginManager.py
plugins

Skib/Server/Python/skib/plugins:
default
__init__.py

Skib/Server/Python/skib/plugins/default:
default.py
__init__.py

in all the __init__.py files I have the __all__=["blah","blah"]
statement. When I try it as:

from skib import PluginManager
PluginManager.init_plugins()

It works. But when I try it like that:

import skib
skib.PluginManager.init_plugins()

It raises AttributeError and complains that there is nothing called
PluginManager. Subpackages also behave like that. The __init__.py files
only contain the __all__ directive. No actual code are in them. Am I
missing a point?

Thanks.

I think that is because skib/PluginManager.py was never imported. Putting

import PluginManager

into skib/__init__.py should do (just a guess, though).

Right (though I should warn I didn't actually read your directory
structure, Tongu). An __init__.py is required for packages, and in
order to import stuff from the package, you have to import that stuff
into __init__.

__all__ is just for

from skib import *


which you almost certainly don't (or shouldn't) want anyway.
