CRUD

DELETEアクション

code:shor.html.erb

<%= link_to "Destroy", article_path(@article), data: {

turbo_method: :delete,

turbo_confirm: "Are you sure?"

} %>

we use the data option to set the data-turbo-method and data-turbo-confirm HTML attributes of the "Destroy" link. Both of these attributes hook into Turbo, which is included by default in fresh Rails applications. data-turbo-method="delete" will cause the link to make a DELETE request instead of a GET request. data-turbo-confirm="Are you sure?" will cause a confirmation dialog to appear when the link is clicked. If the user cancels the dialog, the request will be aborted.
