[Rails] I tried using the button_to method for the first time
Introduction
I am creating an original app with Rails. I wanted to execute the update action directly from the page displayed by the index action, so I used the button_to method.
- Apps created so far will transition from the index with registration list information such as tweets to the details (show) page. From there, you will be taken to the edit page to update the information. I omitted this show and edit actions and performed the update action directly.
Development environment ruby 2.6.5 Rails 6.0.3.4

- Difference from link_to
1. How to use button_to
Similar to the commonly used link_to, you can create buttons instead of links. It's simple and consists of button names, paths, actions and options. The default HTTP method is post.
ruby:○○.html.erb
<%= button_to "Button name", {Path or controller name and action name}, {option} %>
The ones I created this time are as follows. suggestion_path (suggestion.id) is the path set in the update routing. The HTTP method of the update action is patch, so you need to change it from the default post.
ruby:index.html.erb
<%= button_to "Cleaning completed", suggestion_path(suggestion.id), method: :patch, class: "register-blue-btn" %>
2. Difference from link_to
The default HTTP method for link_to is get. Also, link_to creates a link using the a tag, while button_to creates a form.
Reference page [Rails] Explains how to use button_to in an easy-to-understand manner! that's all
** Impression ** I still don't understand this area properly, but if you want to perform an action, is it button_to? Since you can also specify the controller, it seems that you can also execute actions of other controllers.
