How can scrapy export items to separate csv files per item

Question

I am scraping a soccer site and the spider (a single spider) gets several kinds of items from the site\'s pages: Team, Match, Club etc. I am trying to use the CSVItemExporte

Answer 1

I have tried the answer. It seems do not work in the latest version (2.21).

I have included my code for your reference:

class MultiCSVItemPipeline(object):
    SaveTypes = ['CentalineTransactionsItem','CentalineTransactionsDetailItem','CentalineBuildingInfo']

    def open_spider(self, spider):
        self.files = dict([ (name, open(name+'.csv','w+b')) for name in self.SaveTypes ])
        self.exporters = dict([ (name,CsvItemExporter(self.files[name])) for name in self.SaveTypes])
        [e.start_exporting() for e in self.exporters.values()]

    def close_spider(self, spider):
        [e.finish_exporting() for e in self.exporters.values()]
        [f.close() for f in self.files.values()]

    def process_item(self, item, spider):
        what = type(item).__name__
        if what in set(self.SaveTypes):
            self.exporters[what].export_item(item)
        return item
