Mapping facilities

Mappings

Mapping templates facilitate the automatic conversion from one system's headings to the target Ruby DB headings.

Thor tasks are provided to generate these templates in the form the datashift loaders expect

    thor help datashift:config:import

The basic idea is that a model and or spreadsheet can be specified, as either the source or destination of mappings.

Completely empty

    thor datashift:config:import -r /softwaredev/myproject/my_migration_mapper.yaml

With an ActiveRecord model's fields as the destination

    thor datashift:config:import -r /softwaredev/myproject/my_migration_mapper.yaml -m SomeModel
