Question

我有以下选择表单。我想把它变成一个复选框。我已经尝试了一段时间但无济于事。我很感激你的帮助

import scrapy
from scrapy.contrib.spiders import Rule, CrawlSpider
from scrapy.contrib.linkextractors import LinkExtractor
from imgur.items import ImgurItem

class ImgurSpider(CrawlSpider):
    name = 'imgur'
    allowed_domains = ['someurl.com/']
    start_urls = ['http://someurl.com/news']
    rules = [Rule(LinkExtractor(allow=('/node/.*')), callback='parse_imgur', follow=True)]

    def parse_imgur(self, response):
        image = ImgurItem()
        image['title'] = response.xpath(\
            "//h1[@class='pane-content']/a/text()").extract()
        rel = response.xpath("//img/@src").extract()
        image['image_urls'] = response.xpath("//img/@src").extract()
        return image

下面的内容应该

var chats = []; // global in this instance

var promise =  $http.get("http://127.0.0.1:5000/mobile/")
.then(function (response) {
   console.log(response.data.hits);
   for(var i=0; i < response.data.hits.length; i++)
   {
    console.log(response.data.hits[i]._id);
   }

   chats = response.data.hits; // assign hits[] to chats

   return response.data;
 });

if(chats.length !== 0)
  // do something

Rails将select转到checkbox_as_taggable_on复选框
