Hi Dancer users
I hope you can help me.  I'm pretty new to Dancer and I'm trying to 
write a simple web service for note taking.  The SimpleCRUD module 
looks perfect for my needs, but I need to add a timestamp to the 
record that SimpleCRUD creates.
From the documentation I assume the right way to do this is with the 
'add_edit_row_pre_save' hook, but the code in that sub doesn't seem to 
ever get called.
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.
...
simple_crud(
      record_title => 'Log item',
      prefix => '/crud',
      db_table => 'prototype',
      editable => 1,
editable_columns => [ qw( UFirstName ULastName Details Type KFirstName 
KLastName Outcome ) ], add_edit_row_pre_save => sub {
            my $row = shift;
            open TESTOUTPUT, ">", "TEST.txt" or die "$!";
            print TESTOUTPUT "hello";
            close TESTOUTPUT;
},
);
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 {
    ...
};
...
Does anyone have some sample code or tips on how to implement 
'add_edit_row_pre_save' that they would be willing to share?  My 
Googling turned up nothing.
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!
