[Introduction to Rails] form_with (local: true)

Regarding form_with recommended by Rails 5.1, this time I will briefly explain one of the options local: true.

local: What is true

<%= form_with(model: @user, local: true) do |f| %>

https://railsdoc.com/page/form_with There is a list of options in this Rails document, but according to the explanation here, "remote transmission is disabled (default is false)". In other words, if local: true is not entered, asynchronous communication (communication by Ajax) will be performed. If you enter local: true, asynchronous communication will be canceled and the form can be submitted as HTML.

Regarding Ajax, the following article was very easy to understand. https://pikawaka.com/word/ajax

If you have any supplements, please comment!
