Upload file, read first 10 lines

Rails
1

I have a csv file and in my controller:

uploaded_file = params[:upload][:csv].read
@rows << FasterCSV.parse(uploaded_file)

I want to put in @rows only the first 10 lines but the read method
reads all the file.
How can I do?

I think you can do something like
FasterCSV.foreach( uploaded_file) do |row|

do something for first 10 rows then break out

end

I’ve solved with:

uploaded_file = params[:upload][:csv].read
FasterCSV.parse(uploaded_file) do |row|
@rows[i] = row
i += 1
break row if i == 10
end
