Syntax and working of form_with in Ruby on Rails 6?

Question

Ruby on Rails

I tried to understand how form_with works, I looked for Ruby on Rails Docs , RusRails , but I didn’t understand what was happening:

<%= form_with scope: :article, url: articles_path, local: true do |form| %>
  <p>
    <%= form.label :title %><br>
    <%= form.text_field :title %>
  </p>

  <p>
    <%= form.label :text %><br>
    <%= form.text_area :text %>
  </p>

  <p>
    <%= form.submit %>
  </p>
<% end %>

If it's not difficult, then you can explain the syntax of the moments, how it works, and what is the "crutch" with the variable |form|?

If you don't understand how to work with blocks in Ruby, I advise you to read the basics
https://www.rubyguides.com/2016/02/ruby-procs-and-...

form_with(...) do |form|
end

This code generates a form with the fields needed to create and modify an Article. To understand the magic of articles_path, you need to play around with the team rails routesand understand what CRUD, REST are.
You can see what form code is generated by generation in the browser.
