[RUBY] [Rails] About local: true described in form_with

Why write local: true

When submitting a form with rails, describe local: true under form_with, At first, I didn't understand the meaning and wrote the code by imitating it without thinking deeply about what it was.


However, it is unpleasant to proceed with learning without understanding the meaning, so when I looked it up again, In rails5, if you do not describe local: true, it means sending the form by ajax communication, so when you send the form as HTML, you need to describe local: true.
