Here's a little snippet to take it further and convert it to ActiveRecord objects: ``` dom_ids = params[ :dom_ids ].split( "," ) # "facility_2035637462,diagram_184" => [ "facility_2035637462", "diagram_184" ] objects = dom_ids.collect do |dom_id| klass, id = dom_id.split( /_(?!.*_)/ ) # Parse out the class and the id from the dom_id String. klass.classify.constantize.find( id ) end ``` Super handy! Here’s a little snippet to take it further and convert it to ActiveRecord objects:

“`
dom_ids = params[ :dom_ids ].split( “,” ) # “facility_2035637462,diagram_184″ => [ "facility_2035637462", "diagram_184" ]

objects = dom_ids.collect do |dom_id|
klass, id = dom_id.split( /_(?!.*_)/ ) # Parse out the class and the id from the dom_id String.
klass.classify.constantize.find( id )
end
“`
