Is there a programmatic way to find the different associations that an particular model has?

For example, if I have the following:

class File < ActiveRecord::Base   belongs_to :directory   has_many :comments end

is there a way to get the list of symbols/strings that this class has associated under the has_many association?

Is there a programmatic way to find the different associations that an particular model has?

Take a look at YourClass.reflections and the various reflect_on_xxx methods
