我正在尝试在我的 pipelines.py 中导入一个 django 应用程序的模型，以使用 django orm 保存数据。我在第一个涉及的 django 应用程序“app1”中创建了一个scrapy项目scrapy_project(顺便说一下，这是一个不错的选择吗？)。
我将这些行添加到我的 scrapy 设置文件中:
def setup_django_env(path):
import imp, os
from django.core.management import setup_environ
f, filename, desc = imp.find_module('settings', [path])
project = imp.load_module('settings', f, filename, desc)
setup_environ(project)
current_dir = os.path.abspath(os.path.dirname(os.path.dirname(__file__)))
setup_django_env(os.path.join(current_dir, '../../d_project1'))
当我尝试导入 django 应用程序 app1 的模型时，我收到以下错误消息:
Traceback (most recent call last):

raise ImportError, "Error loading object '%s': %s" % (path, e)
ImportError: Error loading object 'scrapy_project.pipelines.storage.storage': No module named dydict.models
为什么scrapy 不能访问django 应用程序模型(给定installed_app 中的app1)？
最佳答案
尝试:
from .. models import MyModel
或
from ... models import MyModel
每个点代表位置
