Scrapy ImportError를 : 이름 없음 모듈 없다 '설정'

Question

나는 웹 사이트에서 일부 데이터를 긁어 postgree의 데이터베이스에 저장하려면 원하는,하지만 난 다음 오류 받고 있어요 :

ImportError: No module named 'settings'

내 트리 뷰를 폴더는 다음과 같습니다

Coder 
├── coder_app 
│   ├── __init__.py 
│   ├── items.py 
│   ├── models.py 
│   ├── pipelines.py 
│   ├── settings.py 
│   └── spiders 
│    ├── __init__.py 
│    └── livingsocial.py 
├── output.json 
└── scrapy.cfg 

스파이더 코드는 다음과 같습니다 :

# -*- coding: utf-8 -*- 
import scrapy 
from coder_app.items import CoderItem 
# from scrapy.loader import ItemLoader 


class LivingsocialSpider(scrapy.Spider): 
    name = "livingsocial" 
    allowed_domains = ["livingsocial.com"] 
    start_urls = (
     'http://www.livingsocial.com/cities/15-san-francisco', 
    ) 

    def parse(self, response): 
     # deals = response.xpath('//li') 
     for deal in response.xpath('//li[a//h2/text()]'): 
      item = CoderItem() 
      item['title'] = deal.xpath('a//h2/text()').extract_first() 
      item['link'] = deal.xpath('a/@href').extract_first() 
      item['location'] = deal.xpath('a//p[@class="location"]/text()').extract_first() 
      item['price'] = deal.xpath('a//div[@class="deal-price"]/text()').extract_first() 
      item['end_date'] = deal.xpath('a//p[@class="dates"]/text()').extract_first() 
      yield item 

Pipeline.py은 다음과 같습니다

from sqlalchemy import create_engine, Column, Integer, String, DateTime 
from sqlalchemy.engine.url import URL 
from sqlalchemy.ext.declarative import declarative_base 

import settings 

DeclarativeBase = declarative_base() 


def db_connect(): 
    """ 
    Performs database connection using database settings from settings.py. 
    Returns sqlalchemy engine instance 
    """ 
    return create_engine(URL(**settings.DATABASE)) 


def create_deals_table(engine): 
    """ 
    Performs table creation 
    """ 
    DeclarativeBase.metadata.create_all(engine) 

class Deals(DeclarativeBase): 
    """Sqlalchemy deals model""" 
    __tablename__ = "deals" 

    id = Column(Integer, primary_key=True) 
    title = Column('title', String) 
    link = Column('link', String, nullable=True) 
    location = Column('location', String, nullable=True) 
    #original_price = Column('original_price', String, nullable=True) 
    price = Column('price', String, nullable=True) 
    end_date = Column('end_date', DateTime, nullable=True) 

및 settings.py은 다음과 같습니다 :

from sqlalchemy.orm import sessionmaker 
from coder_app.models import Deals, db_connect, create_deals_table 


class CoderPipeline(object): 
    def process_item(self, item, spider): 
     return item 

class LivingSocialPipeline(object): 
    """Livingsocial pipeline for storing scraped items in the database""" 
    def __init__(self): 
     """ 
     Initializes database connection and sessionmaker. 
     Creates deals table. 
     """ 
     engine = db_connect() 
     create_deals_table(engine) 
     self.Session = sessionmaker(bind=engine) 

    def process_item(self, item, spider): 
     """Save deals in the database. 

     This method is called for every item pipeline component. 

     """ 
     session = self.Session() 
     deal = Deals(**item) 

     try: 
      session.add(deal) 
      session.commit() 
     except: 
      session.rollback() 
      raise 
     finally: 
      session.close() 

     return item 

Model.py 코드는

BOT_NAME = 'coder_app' 

SPIDER_MODULES = ['coder_app.spiders'] 
NEWSPIDER_MODULE = 'coder_app.spiders' 

DATABASE = { 
    'drivername': 'postgres', 
    'host': 'localhost', 
    'port': '5432', 
    'username': 'mohib', 
    'password': '100200', 
    'database': 'scrape' 
} 
ITEM_PIPELINES = { 
    'coder_app.pipelines.LivingSocialPipeline': 300, 
} 

왜 내가 또한 내가 시도,이 오류를 얻고있다

code_app.import settings 

model.py하지만 다음 오류가 발생했습니다 :

NameError: name 'settings' is not defined 

저는 정말로 여기에 갇혀 있습니다. 누구든지 나를 도울 수 있습니까? 대신

import settings 

쓰기

from scrapy.utils.project import get_project_settings 

다음 함수 또는 메소드 내부의

Answer 1

: 도움이

settings = get_project_settings() 

희망.
