I currently have a login popup in my header bar which is on every page in my website. I want to be able to reload the current page that the person is on after a successful

Answer 1

If you're looking for a way to get the page to refresh (typically redirect_to :back) with an XHR request, you don't have to look for a way to change the response type - just tell the page to reload with inline JS.

format.js {render inline: "location.reload();" }

Like Elena mentions, this should go in a respond_to block, like so:

respond_to do |format|
  format.js {render inline: "location.reload();" }
end

Answer 2

Since Rails 5 (or maybe older versions), you have a request.referrer method. You simply redirect from controller to referrer and it opens the page where request came from.

redirect_to request.referrer, notice: "You're being redirected"

Answer 3

This syntax is what you want... works in Rails 6

  respond_to do |format|
    format.html { redirect_to request.referrer, notice: "User was successfully WHATEVER." }
  end

Answer 4

In Rails 5 redirect_to :back is improved by:

    redirect_back(fallback_location: root_path)

Answer 5

Rails 5 introduced alternative function:

redirect_back(fallback_location: root_path)

It redirect back whenever the HTTP_REFERER is known. Otherwise it redirects to the fallback_location.

The redirect_to :back is deprecated in Rails 5.0 https://github.com/rails/rails/pull/22506 and removed since Rails 5.1

Answer 6

For my application, I use redirect_to :back and it does the trick. However, I doubt this might have an error in a non general use case(s) (user came from a special page?) but i haven't found it so far in my app.
