没有使用sys.path.append命名的模块

Question

I'm trying import models from my Django project to another project. I found two solutions: first using os.environ['PYTHONPATH'] and second using sys.path.append(). My project structure:

-Project1(Django Project)
- mysite
- settings.py
- ...
- app1
- models.py
- ...

Project2(no Django Project)
- test
- dog.py

And in dog.py file:

import sys
import os

sys.path.append("/home/jack/workspace/Project1/mysite")
os.environ['DJANGO_SETTINGS_MODULE'] ="mysite.settings"
from app1 import models

But console show me:

from app1 import models
ImportError: No module named app1

Answer 1

You seem to be adding path to mysite package, not Project1 . But app1 is located in Project1 , so Python can't find it.

Try this:

sys.path.append("/home/jack/workspace/Project1")

Answer 2

From your drawing, app1 is a sibling to mysite —that is, it's in /home/jack/workspace/Project1/app1/ , not /home/jack/workspace/Project1/mysite/app1/ .

So, sys.path.append("/home/jack/workspace/Project1/mysite") isn't going to do you any good; you need `sys.path.append("/home/jack/workspace/Project1/")'.
