Answer 1

2 ways to solve the issue:

1. "redirect_to :back"
2. save params[:page] and redirect to the page once item is deleted

Answer 2

You can use method total_pages on instance variable which you are using for pagination.

example :
@user = User.find(params[:id])
@comments = @user.comments.paginate(:page => 1, :per_page => 20)
@comments.total_pages

@comment.total_pages will return you the last page no. which you can use for your redirection.
