python-3.x - 如何将scrapy数据中的数据发送到django模型？

Question

是否可以在 django 中使用 scrapy 创建新产品？

每当我运行 scrapy.py 时，我都会收到以下错误:

raise ImproperlyConfigured(
django.core.exceptions.ImproperlyConfigured: Requested setting INSTALLED_APPS, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings.

我的应用程序模型文件

from django.db import models

# Create your models here.

class Product(models.Model):
    name = models.CharField(max_length=50)
    age =  models.IntegerField()
    content =  models.TextField(max_length=400)
    def __str__(self):
        return self.name

scrapy.py文件

from models import Product

Product.objects.create(name='BMW', age=25, content='cool car')

是的，当然可以，您只需导入 django 并配置 DJANGO_SETTINGS_MODULE 变量即可:

import django
import os

# Configure settings for project
# Need to run this before calling models from application!
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'app_name.settings') # Replace app_name with your application name.

# Import settings
django.setup()

# Import the models now
from app_name.models import Product

# Use the imported model
product = Product.objects.create(...)
