Run controller method in a rails view on click

Hi!, I've a little question here:

I have a method in my controller called "button" (just for practice):

def button
  puts "hi there"
end

The thing is that I want to run this method only when I click a button in my html.erb view, how can I dod this?

Thanks.

OK, so first you need a route that will point to this action in your routes.rb. Something like:

get '/button', to: 'your_controller_name#button`, as: 'button`

(I use a get verb here, but in case of buttons you will most likely use a POST or PUT verb)

You will also need some empty view file named button.html.erb in the proper controllers subforlder - this is where the page will redirect you after the click..

Last step would be adding a button to your original view file. Something similar to this:

<%= button_to 'Press me', button_path, method: :get %>

It's good for practice - knowing what parts are needed to fire up an action in the controller.
