Class Method Details

.template_identifier(payload) ⇒ Object

Returns identifier relative to Rails.root. Rails supports different template types and returns corresponding identifiers:

  • Text template: the identifier is “text template”

  • Html template: the identifier is “html template”

  • Inline template: the identifier is “inline template”

  • Raw template: the identifier is the file path of the template

Therefore, the amount of returned identifiers is static.
