How to create simple refresh page link with Ruby on Rails

Question

I am fairly new to ruby on rails, and am experimenting with the structure and functionality of RoR and want to know how to create a simple reload link using RoR instead of the static HTML way

it will be good if you can add it in the javascript rather than in your rails code. in rails you can do redirect_to :back — Sabyasachi Ghosh, Sep 12 '13 at 09:23
I have a list of URL's that RoR fires off and presents the response code from the given URL's so I can quickly present environments that are up or down etc — Stacker-flow, Sep 12 '13 at 09:27

An attacker can send someone else a link and that way decide the arguments for `url_for`. That can probably be used to make the "reload" link do stuff it shouldn't. – Rune Schjellerup Philosof Jun 15 '17 at 14:03

If you just do an empty string for the url: <%= link_to "Refresh", "" %>, that will link back to current page. Assuming you want to clear the params.

If you want a refresh with the params then do as @bubblez answered:

<%= link_to "Refresh", url_for(params) %>.

It is better to keep it doing with Javascript. Rails could help you in case you want to redirect.

I'm not entirely sure why you want to just reload the page. (Probably need a bit more context) but you could just generate a link on the page that will reload it like this:

<%= link_to "reload", root_path %>

That will just output a link to the root_path, you can redirect back to whatever page you are currently on by changing the second parameter in the link_to helper. For list of routes, run "rake routes".

What do you mean by fires off? Are you doing this asynchronously? – derekyau Sep 12 '13 at 09:29
Well I am using Net:HTTP to go to the URL I have defined and present back the response code next to the URL – Stacker-flow Sep 12 '13 at 09:30
Okay, starting to make more sense.. So you want the page to just reload and essentially refresh all of these statuses? – derekyau Sep 12 '13 at 09:32

If thats the case, I would go for a simple link_to call with a path back to your current page, or simply do it through JS – derekyau Sep 12 '13 at 09:33
What is your current controller and controller action that renders this view? – derekyau Sep 12 '13 at 09:35
