How to get activerecord associations via reflection

Question

For normal columns, you can get at them via the columns class method. However, associations may be named something quite different if the foreign_key

Answer 1

For an ActiveRecord object I use:

object._reflections

So, I can manipulate the Hash returned. For instance:

object._reflections.keys.each do |key|
    object.public_send(key).destroy_all
end

The above example delete all the relationships from database.
