Using a PG database filled with registered voters.
Trying to set it up so I can search by first name, last name, zip or city. I want to be able to find all voters that match all of the entered params, but having trouble dealing with empty search fields.
where("zip LIKE ? OR city LIKE ? OR last_name LIKE ? OR first_name LIKE ?",
"#{params[:zip]}","#{params[:city]}","#{params[:last_name]}","#{params[:first_name]}")
Is there a better way to build it out so that it matches ALL entered parameters, but ignores empty string parameters? Right now if I enter a first and last name 'John Smith' I will get 'John Jones' and 'Jane Smith'.
