Scrapy image download how to use custom filename

Question

For my scrapy project I\'m currently using the ImagesPipeline. The downloaded images are stored with a SHA1 hash of their URLs as the file names.

How can I s

Answer 1

I did a nasty quick hack for that. In my case, I stored the title of image in my feeds. And, I had only 1 image_urls per item, so, I wrote the following script. It basically renames the image files in the /images/full/ directory with the corresponding title in the item feed that I had stored in as json.

import os
import json

img_dir = os.path.join(os.getcwd(), 'images\\full')
item_dir = os.path.join(os.getcwd(), 'data.json')

with open(item_dir, 'r') as item_json:
    items = json.load(item_json)

for item in items:
    if len(item['images']) > 0:
        cur_file = item['images'][0]['path'].split('/')[-1]
        cur_format = cur_file.split('.')[-1]
        new_title = item['title']+'.%s'%cur_format
        file_path = os.path.join(img_dir, cur_file)
        os.rename(file_path, os.path.join(img_dir, new_title))

It's nasty & not recommended. But, it is a naive alternative approach.
