Form_with search field in Rails 5.1

Question

In Rails 5.1, all forms must be executed using form_with. At http://edgeguides.rubyonrails.org/5_1_release_notes.html#unification-of-form-for-and-form-tag-into-form-with I can only find examples for forms related to models.

What is the correct way for this version of Rails 5.0 in Rails 5.1 using form_with?

<%= form_tag("/search", method: "get") do %>
  <%= label_tag(:q, "Search for:") %>
  <%= text_field_tag(:q) %>
  <%= submit_tag("Search") %>
<% end %>

Answer 1

Here is a call form_withthat is exactly equivalent to a call form_tagfrom a question:

<%= form_with url: '/search', method: :get, local: true do |f| %>
  <%= f.label :q, "Search for:" %>
  <%= f.text_field :q, id: :q %>
  <%= f.submit "Search" %>
<% end %>

, form_with XHR (a.k.a remote: true) , local: true, form_tag remote: false.
