+## Using the ORM in async routes
+
+Django's support for async is currently limited, if you need to do run any query in an async route (or function),
+you need to either use the async equivalent of the query or use `sync_to_async` from `asgiref.sync` to run the query:
+
+```python
+from asgiref.sync import sync_to_async
+
+@app.get("/questions")
+async def get_questions():
+    def _fetch_questions():
+        return list(Question.objects.all())
+
+    questions = await sync_to_async(_fetch_questions)()
+
+    return [{"question": question.question_text} for question in questions]
+
+
+@app.get("/questions/{question_id}")
+async def get_question(question_id: int):
+    question = await Question.objects.filter(id=question_id).afirst()
+
+    return {"question": question.question_text}
+```
