Scrapy: Guide to saving to CSV with custom column settings

Question

So basically I'm scraping data from the web and I have a project file imported into my main spider file. Now, when I grab the data and store it in a container and save it as a csv, the linked column always ends up being the first column in the csv. How to set the position of a custom column?

pName = response.css('#search .a-size-medium').css('::text').extract()
        pPrice = response.css('#search .a-price-whole').css('::text').extract()
        imgs = response.css('.sbv-product-img , .s-image-fixed-height .s-image').css('::attr(src)').extract()

        for prod in zip(pName , pPrice , imgs):        
            items['prodName'] = prod[0]     
            items['price'] = prod[1]        
            items['imgLink'] = prod[2]      
            
            yield items

Answer 1

Use the FEED_EXPORT_FIELDS settings in the settings.py file or spider custom_settings properties. The columns will be arranged in the order you set in Settings Values.

For example:

class MySpider(scrapy.Spider):

    custom_settings = {
        "FEED_EXPORT_FIELDS": ["prodName", "price", "imgLink"]
    }

Or in settings.py:

FEED_EXPORT_FIELDS=["prodName", "price", "imgLink"]
