I am new to python programming and using scrapy. I have setup my crawler and so far it was working until I got to the point where I wanted to figure out how to download images. The error I am getting is cannot import name NsiscrapePipeline. I dont know what I am doing wrong and I dont understand some of the documentation as I am new. Please help
Items File
from scrapy.item import Item, Field
class NsiscrapeItem(Item):
# define the fields for your item here like:
# name = Field()
location = Field()
stock_number = Field()
year = Field()
manufacturer = Field()
model = Field()
length = Field()
price = Field()
status = Field()
url = Field()
pass
Spider

allowed_domain = ["yachtauctions.com"]
start_urls = [
"http://www.yachtauctions.com/inventory/"
]
def parse(self, response):
hxs = HtmlXPathSelector(response)
sites = hxs.select('//tr')
items = []
for site in sites:
item = NsiscrapeItem()
item['location'] = site.select('td[2]/text()').extract()
item['stock_number'] = site.select('td[3]/a/text()').extract()
item['year'] = site.select('td[4]/text()').extract()
item['manufacturer'] = site.select('td[5]/text()').extract()
item['model'] = site.select('td[6]/text()').extract()
item['length'] = site.select('td[7]/text()').extract()
item['price'] = site.select('td[8]/text()').extract()

item['url'] = site.select('td[1]/a/@href').extract()
item['image_urls'] = site.select('td/a[3]/img/@data-original').extract()
item['images'] = item['image_urls']
yield Request(item['url'][0], meta={'item':item}, callback=self.product_detail_page)
def product_detail_page(self, response):
hxs = HtmlXPathSelector(response)
item = response.request.meta['item']
#add all images url in the item['image_urls']
yield item
settings
ITEM_PIPELINES = ['scrapy.contrib.pipeline.image.NsiscrapePipeline']
IMAGES_STORE = 'c:\Python27\NSIscrape\IMG'
IMAGES_EXPIRES = 90
Pipelines This is where I am unsure if I am missing something
from scrapy.item import Item
class NsiscrapePipeline(Item):
image_urls = Field()
images = Field()
def process_item(self, item, spider):
return item

That isn't part of the library :) - at least by looking at their current master branch
I think you're looking for
ImagesPipeline
Their example may help! example
p.s. I don't think you custom name the class - at least not by how scapy is designed; i'm reasonably sure you use their class ;)
Heres my final code thats working. There was two issues
1: I was missing the second backslash that needede to be in the request --> //td[1]/a[3]/img/@data-original
2: I had to check the full URL in which the image would be displayed and join them together which was the main URL or the allowed URL and the image URL.
You tried to pass list, but this function accepts only string. Pass only one element from list (for example list[0]).
