Overview

Assets represent the files that comprise your theme. There are different buckets which hold different kinds of assets, each corresponding to one of the folders within a theme's zip file: “layout”, “templates”, “snippets”, “assets”, and “config”. The full key of an asset always starts with the bucket name, and the path separator is a forward slash, like layout/theme.liquid or assets/bg-body.gif.

Initialize with a key:

asset = ShopifyAPI::Asset.new(:key => 'assets/special.css', :theme_id => 12345)

Find by key:

asset = ShopifyAPI::Asset.find('assets/image.png', :params => {:theme_id => 12345})

Get the text or binary value:

asset.value # decodes from attachment attribute if necessary

You can provide new data for assets in a few different ways:

* assign text data for the value directly:
    asset.value = "div.special {color:red;}"

* provide binary data for the value:
    asset.attach(File.read('image.png'))

* set a URL from which Shopify will fetch the value:
    asset.src = "http://mysite.com/image.png"

* set a source key of another of your assets from which
  the value will be copied:
    asset.source_key = "assets/another_image.png"

#value ⇒ Object

For text assets, Shopify returns the data in the 'value' attribute. For binary assets, the data is base-64-encoded and returned in the 'attachment' attribute. This accessor returns the data in both cases.
