For example $0.99 would instead become 99&cent;. <br /> <br /><code> <br />def number_to_currency_with_cents(number, options = {}) <br /> options = options.stringify_keys <br /> precision = options.delete('precision') { 2 } <br /> unit = options.delete('unit') { '$' } <br /> fractional_unit = options.delete('fractional_unit') { '&cent;' } <br /> separator = options.delete('separator') { '.' } <br /> delimiter = options.delete('delimiter') { ',' } <br /> separator = '' unless precision > 0 <br /> begin <br /> fraction = number.abs % 1.0 <br /> body = number.floor <br /> if body != 0 || body == 0 && fraction == 0 then <br /> parts = number_with_precision(number, precision).split('.') <br /> unit + number_with_delimiter(parts[0], delimiter) + separator + parts[1].to_s <br /> else <br /> (fraction * 100).to_i.to_s + fractional_unit <br /> end <br /> rescue <br /> number <br /> end <br />end <br /></code> <br /> <br />I'm really tempted to go through and replace that whole thing with my own code, but it works, so I'm happy.

I'm sure they did usability studies and whatnot. <br /> <br /><code>ActiveSupport::CoreExtensions::Time::Conversions::DATE_FORMATS.merge!( <br /> :gmail => lambda { |date| <br /> Time.now.beginning_of_day <= date ? <br /> "#{date.strftime('%I').to_i}:#{date.strftime('%M')} #{date.strftime('%p').downcase}" : <br /> Time.now.beginning_of_year <= date ? <br /> "#{date.strftime('%b')} #{date.day}" : <br /> "#{date.month}/#{date.day}/#{date.strftime('%y')}" <br /> } <br />) <br /> <br />ActiveSupport::CoreExtensions::Date::Conversions::DATE_FORMATS.merge!( <br /> :gmail => lambda { |date| <br /> Time.now.beginning_of_day <= date ? <br /> "#{date.strftime('%I').to_i}:#{date.strftime('%M')} #{date.strftime('%p').downcase}" : <br /> Time.now.beginning_of_year <= date ? <br /> "#{date.strftime('%b')} #{date.day}" : <br /> "#{date.month}/#{date.day}/#{date.strftime('%y')}" <br /> } <br />)</code> <br /> <br />Put this code in your "environmen.rb" file in your "RAILS_ROOT/config" directory or make a new Ruby script file containing it in your "RAILS_ROOT/config/initializers" directory.
