Question

So I feel really stupid right now, but I can\'t seem to find an answer.

So I have a method which needs to be called EXACTLY once, and since this is only the experime

Answer 1

<%= form_tag home_action_path, method: :post do %>
  <%= submit_tag 'Call Action' %>
<% end %>

could also use a link

<%= link_to 'Call Action', home_action_path, method: :post %>

or you can use button_to

<%= button_to 'Call Action', home_action_path, method: :post %>

in your routes

post 'home/action'
