尝试解析 Excel 文件时获取 "Not a valid file format"

Question

我正在使用 Ruby 2.3 w 和 Rails 4.2.7。我的 GEmfile 中有这个……

gem 'creek'

我正在尝试解析一个 Excel（“.xls” 而不是 “.xlsx”）文件，就像这样

sheet = creek.sheets[0]
sheet.rows.each do |row|
  my_object_time = service.create_my_object_time_obj(row, race_id)
  if my_object_time.valid?
    results.push(my_object_time)
  else
     puts "#{my_object_time.errors.full_messages}"
  end

但我收到错误...

RuntimeError: Not a valid file format.

在“creek = Creek::Book.new file_location”这一行。是什么赋予了？我愿意使用另一个 gem 来解析 Excel 文件，如果它可以解析 sheet 并以哈希格式给我单元格和值。

Answer 1

好吧，Not a valid file format 不言自明。

Creek documentation 在标题中告诉你这是一个

Stream parser for large Excel(xlsx and xlsm) files.

我对 spreadsheet gem 有很好的体验。

Answer 2

由于其他人可能会在没有简单解释该文件不是 xlsx 文件的情况下以相同的方式结束，我想我会补充说 "Not a valid file format" 是根据文件扩展名抛出的，并且有一个忽略所述扩展的选项，如下所示：

Creek::Book.new path, check_file_extension: false

（取自小溪的示例 test_spec）
