Timeframeable

Timeframeable module allows you to easily extract datetime range from request params keeping you controllers DRY. Intended to use with Rails 3, but may be compatible or easily adaptable with/to other versions.

Add this line to your application's Gemfile:

gem 'timeframeable'

And then execute:

$ bundle

Or install it yourself as:

$ gem install timeframeable

Typical usage:

class FrontController < ApplicationController
  include Timeframeable::Controller
  timeframeable

This will inject dates from params[:start] and params[:end] into @timeframe.start and @timeframe.end. nil will be used if parameter was not found. You can specify default values to avoid this:

  timeframeable :defaults => [:beginning_of_month, :now]

You can specify keys to seek at params hash:

  timeframeable :defaults => [:beginning_of_month, :now],
    :start_key => :s,
    :end_key   => :e

Or even specify instance variable to fill:

  timeframeable :defaults => [:beginning_of_month, :now],
    :start_key => :s,
    :end_key   => :e,
    :variable  => :tf

class Model < ActiveRecord::Base
  include Timeframeable::Scope
end

Model.timeframe(:created_at, @timeframe).count

It might be usefull to add :start_value and :end_value lambda options, which will extract appropriate values from params bypassing :start_key and :end_key.
