wuttasync.importing.wutta

Wutta → Wutta import/export

class wuttasync.importing.wutta.FromWuttaMirror(config, **kwargs)

Base class for Wutta → Wutta data importers/exporters.

This inherits from FromSqlalchemyMirror.

class wuttasync.importing.wutta.FromWuttaToWuttaBase(config, **kwargs)

Base class for Wutta → Wutta data import/export handlers.

This inherits from FromWuttaHandler and ToWuttaHandler.

dbkey = None

Config key for the “other” (non-local) app database. Depending on context this will represent either the source or target for import/export.

define_importers()

This overrides typical (manual) importer definition, and instead dynamically generates a set of importers, e.g. one per table in the target DB.

It does this by calling make_importer_factory() for each class found in the app model.

make_importer_factory(model_class, name)

Generate and return a new importer class, targeting the given data model class.

The newly-created class will inherit from:

• FromWuttaMirror

• ToWutta

Parameters:

• model_class – A data model class.

• name – The “model name” for the importer/exporter. New class name will be based on this, so e.g. Widget model name becomes WidgetImporter class name.

Returns:

The new class, meant to process import/export targeting the given data model.

class wuttasync.importing.wutta.FromWuttaToWuttaExport(config, **kwargs)

Handler for Wutta (local) → Wutta (other) data export.

This inherits from FromWuttaToWuttaBase.

make_target_session()

This makes a “normal” db session, but will use the engine corresponding to the dbkey.

orientation = 'export'

class wuttasync.importing.wutta.FromWuttaToWuttaImport(config, **kwargs)

Handler for Wutta (other) → Wutta (local) data import.

This inherits from FromWuttaToWuttaBase.

make_source_session()

This makes a “normal” db session, but will use the engine corresponding to the dbkey.

orientation = 'import'
