爬出来的数据为什么存不到数据库里去

import pymysql
from doubanmovie import settings*这有问题爬出来的数据存不到数据库里

class DoubanmoviePipeline(object):
def init(self):
self.connect = pymysql.connect(
host=settings.MYSQL_HOST,
db=settings.MYSQL_DBNAME,
user=settings.MYSQL_USER,
passwd=settings.MYSQL_PASSWD,
charset='utf8',
use_unicode=True)
self.cursor = self.connect.cursor()

def process_item(self, item, spider):
    try:
        self.cursor.execute(
            """insert into doubantop250(title,movieInfo,star,quote)
              value (%s,%s,%s,%s)""",
            (item['title'],
             item['movieInfo'],
             item['star'],
             item['quote']))
        self.connect.commit()
    except Exception as err:
        print("重复插入了==>错误信息为：" + str(err))
    return item

应该是这样吧

def process_item(self, item, spider):
    try:
        self.cursor.execute(
            """insert into doubantop250(title,movieInfo,star,quote)
              value (%s,%s,%s,%s)""" %
            (item['title'],
             item['movieInfo'],
             item['star'],
             item['quote']))
        self.connect.commit()
    except Exception as err:
        print("重复插入了==>错误信息为：" + str(err))
    return item
