Question

在运行我的rake任务时遇到访问模块方法的问题，我现在得到的错误是

rake aborted!
NameError: uninitialized constant CustomerTestimonialGrabber

我已经用类似

的类设置了我的模块

require 'open-uri'
require 'nokogiri'

module CustomerTestimonialGrabber
  class Grabber

    def perform
      get_testimonials
   end

   def get_testimonials
     url = 'http://www.ratedpeople.com/profile/lcc-building-and-construction'
     doc = Nokogiri::HTML.parse(open url)

     testimonial_section = doc.css('.homeowner-rating.content-block:not(.main-gallery):not(:last-child)').each do |t|
      title = t.css('h4').text.strip
      comment = t.css('q').text.strip
      author = t.css('cite').text.strip
     end
    Testimonial.where(title: title, comment: comment, author: author).first_or_create!
   end
 end
end

我的rake任务设置了我通常的

namespace :grab do
  task :customer_testimonials => :environment do
    CustomerTestimonialGrabber::Grabber.new.perform
  end
end

有人可以解释为什么我无法访问该模块，我也在我的application.rb文件中设置了这个

config.autoload_paths += %W(#{config.root}/lib)

任何帮助将不胜感激

修改

我已经做了一些阅读，现在在运行我的rake任务之前需要模块

require './lib/customer_testimonial_grabber/grabber.rb'

但现在我似乎无法访问模型本身

NameError: undefined local variable or method `title' for #<CustomerTestimonialGrabber::Grabber:0x00000004be3878>

Answer 1

也许你应该将见证行放在上一个块中？

testimonial_section = doc.css('.homeowner-rating.content-block:not(.main-gallery):not(:last-child)').each do |t|
      title = t.css('h4').text.strip
      comment = t.css('q').text.strip
      author = t.css('cite').text.strip
      Testimonial.where(title: title, comment: comment, author: author).first_or_create!   
end

因为标题没有在它之外定义。
