我的问题是从字符串中删除表情符号,但不使用正则表达式从字符串中删除CJK(中文,日文,韩文)字符.我试着用这个正则表达式:

REGEX = /[^\u1F600-\u1F6FF\s]/i

这个正则表达式工作正常,除了它还检测我需要这些字符的中文,日文和韩文字符.不知道如何解决这个问题？

我一直在谷歌上搜索,似乎我无法找到解决这个问题的方法.所以这是一件事,我目前正与我的同事一起工作rails项目,它工作正常,直到她改变了她的笔记本电脑并从头开始重新设置她的环境......

每当她改变项目的内容时,Gemfile.lock总是在文件末尾写入:

BUNDLED WITH 1.10.0.rc

每次她不小心提交这个gemfile.lock,其他开发人员工作真的很麻烦,因为它总是告诉我们需要提交/碰撞的东西,因为在我们的环境中,它会自动删除它

我花了一整天的时间来了解如何使用标题来存储此CSV Foreach:在RSPEC中为true,然后为ROW和INDEX使用do块.我尝试了几件事,似乎不行.

这是我的模特

class Test

  def self.import(file_path)
    CSV.foreach(file_path, headers: true) do |row, index|
     Here the rest of the code to create/insert record
    end
  end

end

然后在rspec上,我尝试了以下几种方法:

describe "Class" do
  context "successfully insert" do
    let(:data) { "name,lastname\nHero,SuperHero}" }

    before do
      # CSV foreach Stub here
      CSV.stub(:foreach).with("file_path", headers: true).and_return(data)
    end

    it "inserts new record" do
      expect do
       Test.import("file_path")
      end.to change(Test, :count).by(1)
    end
  end
end

它不起作用,它只返回CSV.foreach(file_path,headers:true)的数据,但它不会转到'do block'.

对此有任何帮助,

非常感谢你

我克隆rails app(我们的公司项目),然后安装与mongo db和mongoid gem相关的所有内容.然后我运行rake db:setup然后运行rails s.它工作正常,我可以访问所有网站,并做一切.但我在rails控制台遇到了问题.

每当我这样做:

铁轨

然后

User.first

我会得到这个错误
