Not null query extremely slow in ajax request partial - ruby-on-rails

Question

I have this simple scope
scope :has_video_link,
-> { where.not(video_link: nil) }
I use it like so in my controller
#videos = Message .featured
.includes(:user, :company, :forum, :topic)
.published
.unremoved
.approved
.has_video_link
.order(created_at: :desc)
.paginate(
page: page,
per_page: limit)
Which I call like so
before_action only: :index
skip_before_action :verify_authenticity_token
def index
self.page_title = 'Home'
fetch_videos
end
That works just fine, and my page loads in under a second on prod no problem. My issue is I have an ajax request that calls this
def videos
fetch_videos
respond_to do |format|
format.js
end
end
On dev this works great but in prod this takes over 60 seconds....
First image is from the first times its called (4ms)
2nd image is the ajax call 69000ms...
Any ideas? How do i fix this?? Thank you!!

Answer 1

Solved this issue. All I had to do was simply index video_links and that fixed my issue right up!
