ruby on rails - How to get all the associated models from ActiveRecord object? -

for example have

class order < activerecord::base   has_many :shippings   has_one :contact_information   belongs_to :shop end 

how array of associated objects order. example

order.associations # [:shipping, :contact_information, :shop] 

order.reflect_on_all_associations.map(&:class_name) 

you can pass type of relation parameter: order.reflect_on_all_associations(:has_one)

read activerecord::reflection::classmethods

edit

just realised, you've asked object's associated models.

so, having i've showed, can along following lines:

@some_order = order.first associated_models = @some_order.class.reflect_on_all_associations.map(&:class_name)
