Answer 1

if you are using form_for, use the form_for syntax

<%= form_for(@calculate) do |form| %>
  <%= form.label :number %>
  <%= form.text_field :number %>
  <%= form.label :root %>
  <%= form.text_field :root %>
  <%= form.submit "Submit" %>
<% end %>

this will automatically handle the routes if the @calculate is new object it will submit it to create or if it is already saved it will send a put request to edit action
