In Rails, how to handle multiple checked checkboxes, just split on the , or?

Question

Curious what the \'rails way\' of handling the situation when a user checks multiple checkboxes (with the same name value), and it gets posted back to the controller.

Answer 1

f.check_box :tag_ids, {multiple: true}, 1, nil

Is the right answer:

Here is the reason, there is a 'multiple: true' option that allows your input to be placed in an array. If there isn't a multiple: true option this will not be allowed.
