+### `x-no-relation`
+
+To differentiate a component schema property from one-to-many or many-to-many relation in favour of array(json) of
+related objects, `x-no-relation` (type: boolean, default: false) is used.
+
+```yaml
+        comments:
+          type: array
+          items:
+            $ref: "#/components/schemas/Comment"
+```
+
+This will not generate 'comments' column in database migrations. But it will generate `getComments()` relation in Yii model file.
+
+In order to make it real database column, extension `x-no-relation` can be used.
+
+```yaml
+        comments:
+          type: array
+          x-no-relation: true
+          items:
+            $ref: "#/components/schemas/Comment"
+```
+
+Database column type can be `array`, `json` etc. to store such data.
+
+Now if the Comment schema from the above example is
+
+```yaml
+    Comment:
+      properties:
+        id:
+          type: integer
+        content:
+          type: string
+```
+
+then the value for `comments` can be
+
+```json
+[
+  {
+    "id": 1,
+    "content": "Hi there"
+  },
+  {
+    "id": 2,
+    "content": "Hi there 2"
+  }
+]
+```
+
+`x-no-relation` can be only used with OpenAPI schema data type `array`.

 ## Assumptions
 
 When generating code from an OpenAPI description there are many possible ways to achive a fitting result.
-Thus there are some assumptions and limitations that are currently applied to make this work.
+Thus, there are some assumptions and limitations that are currently applied to make this work.
 Here is a (possibly incomplete) list:
 
 - The current implementation works best with OpenAPI description that follows the [JSON:API](https://jsonapi.org/) guidelines.
   - The request and response format/schema is currently not extracted from OpenAPI schema and may need to be adjusted manually if it does not follow JSON:API
