Ruby on rails rails机械化。单击未定义的方法“单击'；为了#

我在rails中创建了一个mechanize任务。这很简单

task :estimateone => :environment do
  require 'mechanize'

  mechanize = Mechanize.new
  page = mechanize.get('https://www.theurbanlist.com/brisbane/a-list/50-brisbane-cafes-you-should-have-eaten-breakfast-at')
  page.css('ol li a').each do |link|
    link.click
  end

end

但是我犯了这个错误，我做错了什么

由于点击是一种机械化方法，您应该使用它的实例作为点击方法的接收者，而不是链接，这是Nokogiri方法

状态为，它接收元素，单击它并返回获取的页面

尝试：

-- snip --
page.css('ol li a').each do |link|
  mechanize.click(link)
end

Page#带有

的链接将返回链接，css将返回html元素：

page.links_with(css: 'ol li a').each do |link|
  link.click
end
