Ruby on Rails CSV put& quot;& quot;而不是实际的报价 [英] Ruby on Rails CSV putting "" instead of actual quotes

问题描述

我正在尝试生成一个CSV文件。一切都很好，除了空白字段，我不太确定有& quot;& quot; 而不是实际的报价。我提供了我用来生成文件和一些输出的代码。

I am attempting to generate a CSV file. Everything is fine except for blank fields, I'm not quite sure have "" instead of actual quotes. I've provided the code I'm using to generate the file and some output.

<% headers = ["Username", "Name", "E-mail", "Phone Number"] %>
<%= CSV.generate_line headers %>

<% @users_before_paginate.each do |user| %>
  <% row = [ "#{user.username}".html_safe ] %>
  <% row << "#{user.profile.first_name} #{user.profile.last_name}".html_safe unless user.profile.blank? %>
  <% row << "#{user.email}".html_safe unless user.profile.nil? %>
  <% row << "#{user.profile.phone}".html_safe unless user.profile.nil? %>
  <%= CSV.generate_line row %>
<% end %>

输出

Username,Name,E-mail,Phone Number

  admin,LocalShopper ,[e-mail],""
  Brian,Oliveri Design ,[e-mail],727-537-9617
  LocalShopperJenn,Jennifer M Gentile ,[e-mail],""

推荐答案

而不是在数组的每个部分调用html_safe然后从中创建一个新的（非html安全的）字符串，在从 generate_line ：

Instead of calling html_safe on each part of the array and then making a new (non-html-safe) string from it, try calling it at the end, after the string is returned from generate_line:

<%= CSV.generate_line(row).html_safe %>
