rattail.importing

Data Importing Framework

There are a handful of importers and import handlers made available within this namespace, i.e. not just the base classes but some variations thereof etc. You may import each of these directly from this namespace, e.g.:

from rattail.importing import Importer

However it’s more typical to do this instead:

from rattail import importing

That way you can reference importing.Importer as well as importing.model.ProductImporter etc. The full list of what’s available in this rattail.importing namespace follows.

Please also see Data Importers for some of the general concepts involved here.

Importers

• rattail.importing.importers.Importer

• rattail.importing.importers.FromQuery

• rattail.importing.importers.BulkImporter

• rattail.importing.sqlalchemy.FromSQLAlchemy

• rattail.importing.sqlalchemy.ToSQLAlchemy

• rattail.importing.postgresql.BulkToPostgreSQL

Import Handlers

• rattail.importing.handlers.ImportHandler

• rattail.importing.handlers.BulkImportHandler

• rattail.importing.handlers.FromSQLAlchemyHandler

• rattail.importing.handlers.ToSQLAlchemyHandler

• rattail.importing.rattail.FromRattailHandler

• rattail.importing.rattail.ToRattailHandler

Rattail Model Importers

This is a little different but worth a mention. If you do:

from rattail import importing

then you will have access to the full set of Rattail data importers (i.e. the “local” side of an import which targets a Rattail database) via importing.model - in other words you can then do this:

class ProductImporter(importing.model.ProductImporter):
    """ Custom product importer. """

Of course that’s only helpful if you’re importing data to Rattail. See rattail.importing.model for what’s available in that namespace.
