mongoid_time_field

Simple gem to store minutes+seconds or hours+minutes in one integer field in mongoid (as you would do in mysql with time field)

Installation

Include the gem in your Gemfile

gem 'mongoid_time_field'

Usage

class DummyTime
  include Mongoid::Document

  field :worktime, type: TimeField.new(format: 'HH:MM')
  field :time_of_day, type: TimeField.new(format: 'HH:MM:SS')
  field :duration, type: TimeField.new(format: 'mm:SS')
end

Format tokens:

SS - Seconds (always two digits)
MM - Minutes, zero-padded
mm - minutes, no padding
HH - hours, zero-padded to two
hh - hours, no padding
hh? - hours, displays hours only if they are present (non-zero)

Default format is 'hh?:mm:SS'.

Leftmost value in format is of arbitrary length (i.e. format ‘HH:MM’ is not limited to 24 hours, ‘mm:SS’ is not limited to 60 minutes and should not overflow)

All time values are converted and stored in mongodb as seconds (integer field).

changes since v.0.1.0

Default format for deprecated time_field syntax is ‘mm:SS’ for compatibility (If you stored HH:MM with 0.1.0 it should still just keep working with ‘mm:SS’ format, with seconds stored in DB, but if you change to new syntax and use ‘HH:MM’ format, you need to multiply all stored values by 60)
