引用CSV输出中的所有字段

Question

@out = File.open("#{File.expand_path("CSV")}/#{file_name}.csv", "w")
CSV::Writer.generate(@out) do |csv|
  csv << ["01", "02", "test"]
end
@out.close

当我运行上面的代码时,它将值存储在CSV中

01,02.测试

我希望他们存储为

"01","02","测试"

Answer 1

更改

CSV::Writer.generate(@out)do |csv|

至

CSV::Writer.generate(@out, {:force_quotes=>true}) do |csv|
