Rails form_with method: get cannot update a view

Question

Using form_with of rails5, I want to show current time text by clicking GET button. But text isn't updated.

Though I press the button,

Text isn't updated.

Text in response is updated.

users_controller.rb is following.

require 'date'
class UsersController < ApplicationController
  def index
    @message = Time.now.to_s
  end
end                                                                                                     

index.html.erb is following.

<div><%= @message %></div>
<%= form_with method: :get, url: users_path do |form| %>
    <%= form.submit 'SUBMIT'%>
<% end %>
<%= link_to 'LINK', { :controller => :users, :action => :index } %>

Please, tell me how to update text by current time.

NOTE:

When press a link(rendered by link_to helper method), text is updated.

press link...

then text is updated.

why I can update text by link?

EDIT:

Server log when clicking the button is following.

Answer 1

Can you try the following?

<%= form_with method: :get, url: users_path, local: true do |form| %>

Explanation:

I noticed in your logs

Processing by UsersController#index as JS

which means that the form is submitted with format: :js because form_with now defaults to remote: true as you could see HERE (you can't do remote: false however, but instead use local: true), unlike form_for and form_tag where remote: false by default, but you specify remote: true.
