Rails 没有这样的文件或目录@ rb_sysopen。无法从上传目录获取文件内容

Question

我已经用carrierwave保存了svg图标，试试把svg放到layout中？但我收到错误 "not such file"。我该怎么做？

帮手

def show_svg(path)
  File.open(Rails.root.join(path), "rb") do |file|
    raw file.read
  end
end

查看

-@socLinks.each do |link|
      %a{:href => link.link}
        =show_svg link.icon_url.to_s

Answer 1

对我有用

def svg(path)
  file_path = "#{Rails.root}/public#{path}"
  return File.read(file_path).html_safe if File.exists?(file_path) '(not found)'
end

=svg link.icon_url.to_s
