Constructor Details

#initialize ⇒ Base

Provides context and helpers to the corresponding template

Any variable defined in the context of this class will be accessible from the corresponding ERb template. See ruby-doc.org/stdlib-2.2.2/libdoc/erb/rdoc/ERB.html#method-i-result

Usage:

Do not instanciate this class, define subclasses instead an define their template methods as demonstrated in Views::Index.

Conventionally, templates could be stored in images_gallery/templates, but there is no obligation to follow the convention.

This class not meant to be instanciated, subclasses do return View instances (kind of).
