Class Method Details

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

Finds pages by their slug. This method is necessary because pages are translated which means the slug 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.

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.

  Pages::Finder.by_path(path)
end

.find_by_path_or_id(path, id) ⇒ Object

Helps to resolve the situation where you have a path and an id and if the path is unfriendly then a different finder method is required than find_by_path.
