Class YamlFixtureLoader

java.lang.Object

eu.ehri.project.utils.fixtures.impl.YamlFixtureLoader

All Implemented Interfaces:

FixtureLoader

public class YamlFixtureLoader
extends Object
implements FixtureLoader

Load data from YAML fixtures.

The YAML fixture format is almost identical to the plain bundle format, but has some extensions to a) allow for creating non-dependent relationships, and b) allow for single relations to be more naturally expressed. For example, while, in the bundle format the relations for a given relation type is always a list (even if there is typically only one), the YAML format allows using a single item and it will be loaded as if it were a list containing just one item, i.e, instead of writing

     
 relationships: heldBy: - some-repo
     
 

we can just write:

     
 relationships: heldBy: some-repo
