title: How to disable schema checking in FastAPI?
body: <p>I am migrating a service from Flask to FastAPI and using Pydantic models to generate the documentation. However, I'm a little unsure about the schema check. I'm afraid there will be some unexpected data (like a different field format) and it will return an error.</p>
  <p>In the Pydantic documentation there are ways to create a model without checking the schema: <a href="https://pydantic-docs.helpmanual.io/usage/models/#creating-models-without-validation" rel="noreferrer">https://pydantic-docs.helpmanual.io/usage/models/#creating-models-without-validation</a></p>
  <p>However, as this is apparently instantiated by FastAPI itself, I don't know how to disable this schema check when returning from FastAPI.</p>
