Chat API: page_size parameter is ignored when direction=past

sam · August 3, 2025, 11:49pm

Reading through the implementation this appears somewhat deliberate:

plugins/chat/app/services/chat/list_channel_messages.rb

a66897400


      
          def fetch_metadata(channel:, guardian:, target_message_id:, params:)
            ::Chat::MessagesQuery.call(
              channel:,
              guardian:,
              target_message_id:,
              include_thread_messages: !channel.threading_enabled?,
              **params.slice(:page_size, :direction, :target_date),
            )
          end
          
          def fetch_messages(metadata:)
            [
              metadata[:messages],
              metadata[:past_messages]&.reverse,
              (metadata[:target_message] unless metadata[:target_message]&.thread_reply?),
              metadata[:future_messages],
            ].flatten.compact
          end

Perhaps @loic has some thoughts here.
