Python Scrapy django模型导入错误

我一直在尝试使用django和djangoitem设置一个scrapy spider。当我尝试运行spider时，item.py总是无法导入django应用程序的模型

我建立了一个新的django站点，并按照中的说明进行操作，但从我的应用程序导入模型时仍然遇到问题。我认为所有的东西都是按照那个线程中的说明设置的（除了我称之为things testsite而不是mysite等等），但是如果有人认为这可能有帮助，我会发布代码

运行“刮擦爬网”示例时的回溯：

我想你错过了为你的django项目写pythonpath的机会。 您正在添加应用程序，而不是项目

在testbot/settings.py中添加：

# 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'

#设置django的项目完整路径

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

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

试着在

testapp

目录中包含一个空的

\uuuuu init\uuuuuuuuuuy.py

文件。看起来在我运行

python manage.py startapp myapp

时创建了一个空的

\uuuuu init\uuuuuuuuuuuuuuuuy.py

文件，所以我不认为这是错的。你的models.py在哪里？是在myapp文件夹下还是在testapp文件夹下？添加了一个文件树。models.py在testapp下（Rho教程中的myapp）

import sys
import os

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

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