Finally finished simple todo app with Rails: repo. It took way longer than needed and it’s mostly because of Turbo. In Django I did GET request to delete and modify todo status. In Rails with Turbo we can use data: {method: :post} or patch in the link_to like

<%= link_to 'mark done', toggle_status_todo_path(todo), data: {turbo_method: :post} %>

but it didn’t work at first. Logging shows status was changed, but page didn’t refresh that. Even after page reloading it was still incorrect data. Then I deleted some todos and it became normal. Seems finnicky in my case. I recommend to stick to the traditional form method='post|get' for the beginners.
