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

The easiest way of doing this is to set those checkboxes up to become an array.

HTML:

Controller:

tag_ids = params[:tag_ids]

(Of course, you'd probably be using form_for-based helpers in the view, and therefore mass-assigning the tag IDs. This is just the most generic example.)
