require 'rubygems'
    require 'spreadsheet'
    Spreadsheet.client_encoding = 'UTF-8'
     workbook = Spreadsheet.open params[:dump][:excel_file]
     sheet = workbook.worksheet 'database'

I am getting an error if i click on upload button with no file in the
field.

And ? If your code assumes the existence of a param that's not being
provided, why is that a surprise?

Just check that params[:dump][:excel_file] exists before you use it.

You could also disable the upload button by default and enable it using
javascript only if they enter a value in the field.
