# 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.
