我知道您可以通过设置agent.user_agent_alias ='Linux Mozilla'来使用一组预定义的别名,但是如果我想设置我自己的用户代理,因为我正在编写一个Web爬虫,并希望识别它,对于我正在索引的网站.就像Googlebot一样.

似乎有一个user_agent方法,但我似乎找不到任何关于它的功能的文档.

我正在将我的应用程序升级到Rails 4,现在得到了我的rails服务器,以及太阳黑子solr,经过大量的修补,运行后,我可以访问Solr管理页面.但是,当我尝试从我的rails开发应用程序访问solr进行搜索或索引时,我收到以下错误

RSolr::Error::Http (RSolr::Error::Http - 404 Not Found

这是sunspot.yml文件.

production:
  solr:

    port: 80
    log_level: WARNING
    path: /solr/production
    # read_timeout: 2
    # open_timeout: 0.5 …

这已被问了很多,但我仍然面临一些问题.

我收到日期并存储为日期.我需要查询大于和小于,所以我将其更改为时间,再次尝试,但我得到了奇怪的结果.

我这样做

Class.where(:event_date.gt => Time.parse(Date.today))

而我正在创造旧纪录,20世纪40年代,60年代和其他人.我尝试通过在最后添加.utc来转换时间,仅与Date.today进行比较,但到目前为止还没有解决问题.这是Mongoid生成的选择器

selector: {:date_utc=>{"$gte"=>Sat Sep 10 21:00:00 UTC 2011}},

我以"2011-09-11"格式收到日期并将其存储在时间字段中.尝试解析时间utc,没有运气.

任何的想法？我正在使用Mongoid 2.0.2.以后的版本似乎与我正在使用的其他扩展不兼容.

[UPDATE]

所以问题在于1970年之前的旧日期显然.我现在的问题是如何处理它们.

当尝试在Heroku上执行rake或console命令时,我不断收到此错误:

使用CarrierWave和Amazon S3,我能够存储来自本地文件的图像,但是当我尝试从某个URL存储它们时,我得到'TypeError:无法将nil转换为String'

这是我正在尝试的代码

require 'open-uri'
image = "open(image_url)
@object.image.store!(file)

显然@object拥有Uploader图像,它使用本地文件系统工作正常.我试着添加一个

def root Rails.root.join'public /'end

我的上传者也没有运气.

任何的想法？

我注意到以AND/OR/NOT示例('this AND')之类的逻辑运算符结尾的查询将导致错误.现在处理这个问题的最佳方法是什么？只是删除或逃避以其中一个结尾的所有查询？请注意,对于以这些单词之一开头的查询,也会发生这种情况.有时候,有效的名字会以这样的词结尾,比如Oregon OR.
