DateParams

Dates and times passed in as strings date-pickers or time-pickers need to be converted from their string format to a ruby Date or DateTime to be able to be saved and manipulated. This gem provides two simple controller add-ons to facilitate the conversion.

Installation

Rails 3.x and Ruby 1.9.3 or 2.x required.

Add this line to your application's Gemfile:

gem 'date_params'

And then execute:

$ bundle

Or install it yourself as:

$ gem install date_params

Usage

date_params

Specify the dates to be parsed:

class UsersController < ApplicationController
  # e.g. parameters come in as: { sign_up_on: '01/05/2013' }
  date_params :sign_up_on
  # and now params[:sign_up_on] is a Date object
end

Any options that a before_filter accepts can be passed in:

date_params :sign_up_on, only: [:index]

If date fields are namespaced in a model that can be specified with the namespace option:

# will parse parameters in the format of: { user: { searched_on: '01/04/2013', sign_up_on: '04/03/2013' } }
date_params :searched_on, :sign_up_on, namespace: :user

Date format can be passed as an option (default is %m/%d/%Y):

date_params :search_on, :sign_up_on, date_format: '%d-%m-%Y'

datetime_params

Specify the datetime fields that need to be parsed:

class UsersController < ApplicationController
  # e.g. parameters come in as: { sign_up_at_date: '01/05/2013', sign_up_at_time: '7:30 pm' }
  datetime_params :sign_up_at
  # and now params[:sign_up_at] is a timezone-aware DateTime object
end

In addition to the :namespace and :date_format options, the time format can be specified (default is %I:%M %p):

date_params :sign_up_at, time_format: '%H:%M:%S'

To specify exactly which fields should be parsed:

date_params { date: :sign_up_on, time: :sign_up_time, field: :sign_up_at }, only: :create
