Class Method Details

.by_slug(slug, conditions = {}) ⇒ Object

end

.by_title(title) ⇒ Object

Finds pages by their title. This method is necessary because pages are translated which means the title attribute does not exist on the pages table thus requiring us to find the attribute on the translations table and then join to the pages table again to return the associated record.
