尝试一下:
CSV.open("data.csv", "wb") do |csv|
@data.each do |hash|
csv << hash.values
end
end
如果您希望CSV的第一行包含哈希键(有点像标题),只需执行以下操作:
If you want the first line of the CSV to contain the keys of the hash (kind of like a header), simply do:
CSV.open("data.csv", "wb") do |csv|
csv << @data.first.keys # adds the attributes name on the first line
@data.each do |hash|
csv << hash.values
end
end
