The first and most obvious check is that you have at least version 0.91 of Dancer::Plugin::SimpleCRUD installed - as that's the version the add_edit_row_pre_save hook was first added in.

That's not how you use it - it's a Dancer hook registered by the plugin, so you use the normal Dancer hook syntax, e.g.:

hook add_edit_row_pre_save => sub {
