Model

When configuring a data import, start by reviewing the Model.

Your Name » Data import » Models

Choose the correct model for your data import. The user sync always uses the haplo:user-sync model, but other data import processes and REST APIs can use any model provided by your application developers.

Install the haplo_data_import_auto_models plugin to enable simple models based on the types of object in your application. After installation, select the required types:

Your Name » Data import » Models » Select automatic model definitions…

Model administrative interface

For each Destination in the Model, the model page shows:

The Destination name for use in Control files
Whether it depends on another Destination
Whether it’s an optional destination that does not need have to have any data, or is a pseudo-destination which is used to form structured values or load other destinations.
A list of all the Names in that Destination

The columns in the Names table are:

Name	The name which should be used in Control files to refer to this value.
Type	The data type of the value.
MV?	Whether this Name is multi-value.
Req?	Whether a value for this Name is required.
Description	A short description of the values expected.

Some data types will have actions in the right column:

Map links to a page which generates example control file mappings for ref values.

Making Destinations ready for data import

Before data can be set using the Names on a Destination, the Destination must be made ready for data import. The method depends on whether you are changing existing data in the application, or ingesting new data.

The User sync automatically makes Destinations ready, so you must not use new or load instructions.

Ingesting new data

You must explicitly tell the data import framework that the Destination should create new data, using the new Instruction.

Loading existing data for modification

The load Instruction loads existing data for modification. This is a two step process, firstly setting the ‘ref’ (ID) of the object in a pseudo Destination, and then using the load Instruction to load the object into the Destination.

This is separated out into two steps so the full data transformation capabilities of the data import framework can be used to determine which data to load. For example, the haplo:username-to-ref value filter can be used to load user profiles by their username.

See the load Instruction for an example.

Don’t use load or new on dependent Destinations

When a Destinations depends on another Destination, you should not use new or load instructions for those dependent Destinations, as everything happens automatically.
