Friends,
Is there a straightforward way to overload update related methods across
several classes?
I'm setting a value in a field called "is_locked", and when it is set to
1, I want to ignore any method calls that might update the database.
I want related tables to also obey the is_locked field from the first table.
I have done this by overloading update, set_column, set_columns and
store_column.
I originally tried to create a derivative class of 'DBIx::Class' called
'DBIx::LockingClass' containing the methods, but because of the
Class::C3 chain, my overloaded methods in 'DBIx::LockingClass' get
overloaded somewhere else later, and are rendered useless.
( C3 Inheritance Chain )
DBIx::Class::Core, DBIx::Class::Relationship,
DBIx::Class::Relationship::Helpers, DBIx::Class::Relationship::HasMany,
DBIx::Class::Relationship::HasOne, DBIx::Class::Relationship::BelongsTo,
DBIx::Class::Relationship::ManyToMany,
DBIx::Class::Relationship::Accessor,
DBIx::Class::Relationship::CascadeActions,
DBIx::Class::Relationship::ProxyMethods,
DBIx::Class::Relationship::Base, DBIx::Class::InflateColumn,
DBIx::Class::PK::Auto, DBIx::Class::PK, DBIx::Class::Row,
DBIx::Class::ResultSourceProxy::Table, DBIx::Class::ResultSourceProxy,
DBIx::ClientClass, DBIx::Class, DBIx::Class::Componentised,
Class::C3::Componentised, Class::Accessor::Grouped
My current solution was to copy the overloaded methods into each class
defining a table, to bump them to the front of the Inheritance chain.
That's a messy approach, because it makes updates to that code
error-prone, and it gets in the way of other overloads to the same
functions in a few of my classes.
How have y'all approached this problem? Am I missing something obvious?
Kind Regards,
/Mitch
