Method: ActiveAdmin::ViewHelpers::DisplayHelper#display_name_method_for

Defined in:
lib/active_admin/view_helpers/display_helper.rb

#display_name_method_for(resource) ⇒ Object

Looks up and caches the first available display name method. To prevent conflicts, we exclude any methods that happen to be associations. If no methods are available and we’re about to use the Kernel’s to_s, provide our own.
