Instance Method Details

#page_title ⇒ String

Retrieves the current page’s title via I18n.t. Translation keys are derived from the current controller and action. Specifically, the keys “page_title.#{controller_name}.#{action_name}” and “page_title.#{action_name}” are tried. For namespaced controllers, the namespace is included as part of controller_name, dot-separated.

I18n string interpolation is supported using the view’s instance variables. Additionally, the titleize‘d controller name is available in both singular and plural form via the interpolation keys singular and plural, respectively.

This method is memoized to @page_title, and can be invoked multiple times without additional cost. This also allows views to bypass I18n title lookup, if necessary, by assigning to the @page_title variable.

Returns:

  • (String)
