Where is my error (scope)?

Question

Ruby on Rails

Hello.
I can't figure out what's wrong.

scope :between, -> (sender_id, recipient_id) do
    where(“(conversations.sender_id = ? AND conversations.recipient_id = ? ) OR
    (conversations.sender_id = ? AND conversations.recipient_id = ? )”,
    sender_id, recipient_id, recipient_id, sender_id)
  end

I googled the examples - everything seems to be correct, but it swears by a bunch of syntax errors.

/home/dartnyan/Projects/instagram_app/app/models/conversation.rb:10: syntax error, unexpected '?' ...“(conversations.sender_id = ? AND conversations.recipient_... ... ^ /home/dartnyan/Projects/instagram_app/app/models/conversation.rb:10: syntax error, unexpected '?' ... conversations.recipient_id = ? ) OR ... ^ /home/dartnyan/Projects/instagram_app/app/models/conversation.rb:11: syntax error, unexpected '?' ... (conversations.sender_id = ? AND conversations.recipient_... ... ^ /home/dartnyan/Projects/instagram_app/app/models/conversation.rb:11: syntax error, unexpected '?' ... conversations.recipient_id = ? )”, ... ^ /home/dartnyan/Projects/instagram_app/app/models/conversation.rb:12: syntax error, unexpected ')', expecting '='

Rails 5.0, Ruby 2.3

Answer 1

rusrails.ru/active-record-query-interface Section
14.1.
There, the scope with the argument looks like this "scope :created_before, ->(time) { where("created_at < ?", time) }"
Your quotes seem to be wrong.

Answer 2

conversations is an associated model? Might be worth doing a join .
