A small library intended to simplify the common steps involved with importing CSV files to a usable form in Ruby.
Home Page: http://www.pillowfactory.org/pages/csvmapper

in the method read_attributes_from_file we have @parser_options blank given this code:
results = CsvMapper.import("#{Rails.root.to_s}/lib/imported.csv") do
delimited_by ";"
map_to User
after_row lambda{ |row, user| user.save }
read_attributes_from_file
end
I expect at least the :col_sep options to be set. Am I doing something wrong?
Csv-mapper gem works fine. But, i am facing serious problem that values are not present in csv file and its an NOT NULL field in ActiveRecord.
How i assign NOT NULL field using csv mapper gem?
