Scrapy django model import error

I've been trying to set up a scrapy spider using django and djangoitem. When I try running my spider, the item.py always fails to import the django app's model.

I set up a fresh django site and followed the instructions from https://stackoverflow.com/a/19073347/3988392 and I'm still having trouble importing models from my app. I think everything is set up as stated in that thread (except I called things testsite rather than mysite, etc..) But I'll post code if anyone thinks it could be helpful.

Traceback when running scrapy crawl example:

Traceback (most recent call last):

import sys
import os

# Setting up django's project full path.

sys.path.append('/home/testsite')

os.environ['DJANGO_SETTINGS_MODULE'] = 'testsite.settings'

I think you miss to write the pythonpath to your django project. You are adding the app, not the project.

in testbot/settings.py add:

# Setting up django's project full path.
import sys
sys.path.insert(0, '/home/TristanTrim/PycharmProjects/testsite')

# Setting up django's settings module name.
# This module is located at /home/rolando/projects/myweb/myweb/settings.py.
import os
os.environ['DJANGO_SETTINGS_MODULE'] = 'testsite.settings'
