The rails documentation doesn't specify how to do this. Is there a way? How? 回答1: This has a very straightforward solution that is directly supported by check_box (at least as of rails 4, I didn't check older documentation) <%= check_box("tag", tag.id, {checked: true}) %> This will make the checkbox checked. Of course instead of true you will put in

问题 I have a loop in a form and I'm trying to create multiple data with same name but I'm getting an error with my syntax. I had another question to the same application HERE where I had a mass-assignment error because of the numbers in the array <%= form_for [@hourable, @hour] do |f| %> <% (1..7).each do |i| %> <%= select_tag "hour[#{i}][day]", options_for_select(days_hours) %> <%= select_tag "hour[#{i}][open_time]", options_for_select([ ... %> <%= select_tag "hour[#{i}][open_time]", options_for
