Related to this, how would I use dataset methods on the target class?
class User < Sequel::Model(:users)
one_to_many :contacts
end
class Contact < Sequel::Model(:contacts)
def_dataset_method(:search) do |fragment|
grep([:surname, :rest_of_name],
Regexp.new(Regexp.escape(fragment), Regexp::IGNORECASE))
end
end
User.first.contacts.search("a") raises a NoMethodError on Array, again
due to #contacts not being a dataset. I tried to move #search into a
module, and used the :extend option on the #one_to_many call, but this
again raised a NoMethodError on Array. I must misunderstand
how :extend works.
What I came up with is this:
class User < Sequel::Model(:users)
def search_contacts(fragment)
contacts_dataset.search(fragment)
end
end
Any pros/cons of using this method? Or should I be doing it some other
way?
Thanks!
