Duplicate GET requests - Rails & Heroku

I'm trying a solution to resolve a duplication of requests happening in my Ruby on Rails 6 project deployed to Heroku.

This seems to occur when those anchors with hyperlinks are used, so it loads 2x.

As a result, it ends up generating duplicate logs because it also calls the controller (GET -> Controller -> Model -> View).

Below are some logs that prove the duplicate request:

PS: Could this be linked to Turbolink/Load or some internal Rails script like ujs? I have evidence that yes, as I have another application in production using exactly the same setup, however, 1 uses the conventional rails native import scripts and css template (javascript_include_tag, javascript_pack_tag, stylesheet_pack_tag) and the other uses simple HTML meta tags

  • I've already tested it in a local environment and this doesn't happen.
  • I saw some comments about Serviceworker, but I didn't validate it 100%.
  • There is no Loadbalance/Nginx configuration. Direct environment between Heroku with Node/Ruby Buildpacks and the RoR project.
Solution

  • Well, this was actually due to turbolinks, basically there was the section to inject the data-turbolinks-track, reload [schreenshot].

    This problem also did not appear locally because the snippet of this pixel script had a check for the production environment.

    It is also possible to keep the data-turbolinks-track reload, but you need to add data-turbolinks=false in the anchor element

    = link_to "Comprar", levante_checkout_offer_path(offer), class: "btn button-primary", data: { turbolinks: "false" }
    OR
    $(document).on("turbolinks:load", () => {
  $("a").attr("data-turbolinks", "false");
});
