finds an ActionLink by matching the action
# File lib/active_scaffold/data_structures/action_links.rb, line 45 def [](val) links = [] @set.each do |item| if item.is_a?(ActiveScaffold::DataStructures::ActionLinks) collected = item[val] links << collected unless collected.nil? else links << item if item.action.to_s == val.to_s end end links.first end
adds an ActionLink, creating one from the arguments if need be
# File lib/active_scaffold/data_structures/action_links.rb, line 11 def add(action, options = {}) link = if action.is_a?(ActiveScaffold::DataStructures::ActionLink) || action.is_a?(ActiveScaffold::DataStructures::ActionLinks) action else ActiveScaffold::DataStructures::ActionLink.new(action, options) end # NOTE: this duplicate check should be done by defining the comparison operator for an Action data structure existing = find_duplicate(link) unless existing # That s for backwards compatibility if we are in root of action_links # we have to move actionlink into members or collection subgroup group = (name == :root ? subgroup(link.type, link.type) : self) group.add_to_set(link) link else existing end end
adds a link to a specific group groups are represented as a string separated by a dot eg member.crud
