Question

I was trying to update a record in the database using Object.update_attributes(:field => "parameter")
To show a simple example of what I was trying to do is this. Please see the code below

a = params["ORDERNO"].to_s
b =  params["TRACKNO"].to_s    
@bd=Staging.where(:trackno => b , :orderno=> a)
    if @bd.nil? 
       puts "not found"
    else
       @bd.update_attributes(:field_name => "PARAMETER")
    end

I also tried @bd.first.update_attributes(::field_name => "PARAMETER")

Answer 1

A possible solution for this

use update_all(:field_name => "PARAMETER")
