64 # Multiple database operations here
71 An object that behaves much like L<Scope::Guard>, but hardcoded to do the
72 right thing with transactions in DBIx::Class.
78 Creating an instance of this class will start a new transaction (by
79 implicitly calling L<DBIx::Class::Storage/txn_begin>. Expects a
80 L<DBIx::Class::Storage> object as its only argument.
84 Commit the transaction, and stop guarding the scope. If this method is not
85 called and this object goes out of scope (i.e. an exception is thrown) then
86 the transaction is rolled back, via L<DBIx::Class::Storage/txn_rollback>
92 L<DBIx::Class::Schema/txn_scope_guard>.
