+In [dbt Cloud Versionless](/docs/dbt-versions/upgrade-dbt-version-in-cloud#versionless), you can use the improved syntax to define foreign keys, which uses `ref`. This feature will be available in the upcoming 1.9 release. For more information, update the documentation version to 1.9 and refer to the 'What's better about this syntax' section.

+
+#### What's better about this syntax
+
+The recommended syntax means dbt automatically resolves references to other models, ensuring they:
+
+- Capture dependencies
+- Work across different environments
+
+Here's an example showing how to use the recommended syntax:
+
+<File name='models/schema.yml'>
+
+```yml
+models:
+  - name: <model_name>
+
+    # required 
+    config:

+        enforced: true
+

+      - type: foreign_key
+        columns: [id]
+        to: {{ ref('my_model_to') }}  # or {{ source('source', 'source_table') }}
