class normlite.txmodel.operations.Operation

Bases: Protocol

Interface for change requests that process data in the context of a transaction.

Change requests follow a well-defined protocol to accomplish their task of modifying data in a consistent way. Each operation must define:

• stage(): These are the pre-commit activities to validate data prior to committing them.

• do_commit(): All activities to commit data to the database.

• do_rollback(): All activities to revert changes committed prior to this failed change.

stage() → None

Stage and validate the data to be committed.

do_commit() → None

Perform the commit activities associated with this operation.

do_rollback() → None

Perform the rollback activities associated to this operation.

get_result() → dict

Return the result of the last executed Operation.do_commit() or Operation.do_rollback().
