How to send data to scrapy pipeline to mongodb

    from pymongo import MongoClient
    from scrapy.conf import settings
    from scrapy.exceptions import DropItem
    from scrapy import log

    class MongoDBPipeline(object):
        collection_name= 'members'
        def __init__(self, mongo_uri, mongo_db):
            self.mongo_uri = mongo_uri
            self.mongo_db = mongo_db
        @classmethod
        def from_crawler(cls, crawler):
            return cls(
                mongo_uri=crawler.settings.get('MONGO_URI')
                mongo_db=crawler.settings.get('MONGO_DATABASE', 'items')
            )
        def open_spider(self,spider):
            self.client = pymongo.MongoClient(self.mongo_uri)
            self.db = self.client[self.mongo_db]
        def close_spider(self, spider):
            self.client.close()
        def process_item(self, item, spider):
            self.db[self.collection_name].insert(dict(item))
            return item
