python - Scrapy ERROR: Spider must return Request, BaseItem or None, got 'dict' -


i have tried reproducing scrapy tutorial using xpath , keep running error: spider must return request, baseitem or none, got 'dict' in <get http://quotes.toscrape.com/> not sure how fix this.

i'm going share snippets 2 files should enough debugging:

1) spider quotes_spider.py

from scrapy.spider import spider scrapy import request  class quotespider(spider):     name = 'quotes'     start_urls = [         'http://quotes.toscrape.com/',     ]      def parse(self, response):         quote in response.xpath('//div[@class="quote"]'):             yield {             'text': quote.xpath('.//span[@class="text"]/text()').extract(),             'author': quote.xpath('.//small[@class="author"]/text()').extract(),             'tags': quote.xpath('.//div[@class="tags"]/a[@class="tag"]/text()').extract(),             }

2) items.py

from scrapy.item import item  class quotesbotitem(item):     text = scrapy.field()     author = scrapy.field()     tags = scrapy.field()

fyi: in case compare tutorial , wondering why switched extract_first() extract(), it's because seeing error exceptions.attributeerror: 'selectorlist' object has no attribute 'extract_first' unrelated question believe.

you returning dictionary error says , not item

class quotespider(spider):     name = 'quotes'     start_urls = [         'http://quotes.toscrape.com/',     ]  def parse(self, response):     quote in response.xpath('//div[@class="quote"]'):         item = quotesbotitem()         item['text'] = quote.xpath('.//span[@class="text"]/text()').extract()         item['author'] = quote.xpath('.//small[@class="author"]/text()').extract()         item['tags'] = quote.xpath('.//div[@class="tags"]/a[@class="tag"]/text()').extract()         yield item

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
