The difference between Link_to vs Button_to in Ruby on Rails Discussion

Another trick is to use formaction for having multiple buttons in the same form without using any hidden forms.

For example:

<%= form_with model: @blog_post do [form| %> 
  <%= form. submit "Save" %>
  <%= tag.button "Publish", formaction: publish_blog_post_path(@blog_post) %>
<% end %>
