Scrapy: Passing item between methods

Question

Suppose I have a Bookitem, I need to add information to it in both the parse phase and detail phase

def parse(self, response)
    data = json.loads(response)         


        

Answer 1

There is an argument named meta for Request:

yield Request(url, callback=self.detail, meta={'item': item})

then in function detail, access it this way:

item = response.meta['item']
