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.

    :slug => slug
  }.merge(conditions))
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.

def find_by_path(path)
  if ::Refinery::Pages.scope_slug_by_parent
    # With slugs scoped to the parent page we need to find a page by its full path.
    # For example with about/example we would need to find 'about' and then its child
    # called 'example' otherwise it may clash with another page called /example.
    path = path.split('/').select(&:present?)
    page = by_slug(path.shift, :parent_id => nil).first
    page = page.children.by_slug(path.shift).first while page && path.any?
  else
    page = by_slug(path).first
  end

  page
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.

.in_menuObject

Shows all pages with :show_in_menu set to true, but it also rejects any page that has not been translated to the current locale. This works using a query against the translated content first and then using all of the page_ids we further filter against this model’s table.
