# Add a has_many association.
#
# e.g.
#
# class Post
# attribute :user_id, Friendly::UUID
# indexes :user_id
# end
#
# class User
# has_many :posts
# end
#
# @user = User.create
# @post = @user.posts.create
# @user.posts.all == [@post] # => true
#
# _Note: Make sure that the target model is indexed on the foreign key. If it isn't, querying the association will raise Friendly::MissingIndex._
#
# Friendly defaults the foreign key to class_name_id just like ActiveRecord.
# It also converts the name of the association to the name of the target class just like ActiveRecord does.
#
# The biggest difference in semantics between Friendly's has_many and active_record's is that Friendly's just returns a Friendly::Scope object. If you want all the associated objects, you have to call #all to get them. You can also use any other Friendly::Scope method.
#
# @param [Symbol] name The name of the association and plural name of the target class.
# @option options [String] :class_name The name of the target class of this association if it is different than the name would imply.
# @option options [Symbol] :foreign_key Override the foreign key.
#
