holidays_img

A simple wrapper for Rails's image_tag helper. Leveraging the holidays gem, it allows you to load images based on the holiday occurring on a given date.

Add the gem to your application's Gemfile:

gem 'holidays_img'

And then execute:

$ bundle

Simply use the holidays_image_tag helper as you would a standard Rails image_tag:

<%= holidays_image_tag 'image.jpg' %>

To ensure proper loading of images, adhere to the following naming convention:

• Have a default image, used for when a day does not fall on a holiday (also acts as a fallback for when a holiday image cannot be found)
• Name your holiday images in the following format: original_name_holiday_name.ext
• Ensure all holiday images are in the same directory

Naming Example:

image.jpg
image_christmas_day.jpg
image_new_year_s_day.jpg
image_independence_day.jpg
...

See the Holidays gem's definition files for a list of holidays for any available region.

You can configure options using an initializer:

# config/initializers/holidays_img.rb

HolidaysImg.configure do |config|
  # Load holidays based on region, defaults to :us
  config.region    = :ca
  # Only load images for holidays you specify
  config.whitelist = ['Christmas Day', 'Mother\'s Day']
  # Load custom holidays from file, can also pass array of file paths
  config.custom_holidays = '/path/to/custom_holidays.yml'
end

For info on how to format custom holiday definitions, see the Holidays gem's definition syntax documentation.
