Hi there,
What’s the correct & most efficient way to compose the following array?
I have:
Existing tables:
- users (:id)
- user_languages (:id, :user_id, :language_id)
- languages (:id, :name)
Existing array:
@user_languages
Wanted array: (for a specific user)
“@languages” = Languages.find(:all) - (“Languages” whose “:ids” can be
found as “:language_ids” in the existing array “@user_languages”)
Thanks a lot for your help!
Tom
