73 # Multiple database operations here
80 An object that behaves much like L<Scope::Guard>, but hardcoded to do the
81 right thing with transactions in DBIx::Class.
87 Creating an instance of this class will start a new transaction (by
88 implicitly calling L<DBIx::Class::Storage/txn_begin>. Expects a
89 L<DBIx::Class::Storage> object as its only argument.
93 Commit the transaction, and stop guarding the scope. If this method is not
94 called and this object goes out of scope (e.g. an exception is thrown) then
95 the transaction is rolled back, via L<DBIx::Class::Storage/txn_rollback>
101 L<DBIx::Class::Schema/txn_scope_guard>.
107 Inspired by L<Scope::Guard> by chocolateboy.
