It adds the "[]" so the parameter is an array (if you don't add that, params[:avatar] will be only one file and not an array). I'm not sure why but the helper does not infer that, you have to be explicit on that.

--I read this example for the form:<%= p.file_field :avatar, :multiple => true, name: "post_attachments[avatar][]" %>
Why is the name argument necessary Why can't the controller just get the array from <%= p.file_field :avatar %> ?
