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 {
    ...
};

Hmm - looking at the docs, it's not at all clear that they're Dancer
hooks and use the normal Dancer syntax.  I'll try to address that!
