(fields) defined in the `response_model`. If you returned an object |

that contains an attribute `password` but the `response_model` does |

not include that field, the JSON sent to the client would not have |

that `password`. |

* Validation: whatever you return will be serialized with the |

`response_model`, converting any data as necessary to generate the |

corresponding JSON. But if the data in the object returned is not |

valid, that would mean a violation of the contract with the client, |

It could be any valid Pydantic *field* type. So, it doesn't have to |

be a Pydantic model, it could be other things, like a `list`, `dict`, |
|
etc. |
|
|
|
It will be used for: |
|
|
|
* Documentation: the generated OpenAPI (and the UI at `/docs`) will |
|
show it as the response (JSON Schema). |
|
* Serialization: you could return an arbitrary object and the |
|
`response_model` would be used to serialize that object into the |
|
corresponding JSON. |
|
* Filtering: the JSON sent to the client will only contain the data |
|
(fields) defined in the `response_model`. If you returned an object |
|
that contains an attribute `password` but the `response_model` does |
|
not include that field, the JSON sent to the client would not have |
|
that `password`. |
|
* Validation: whatever you return will be serialized with the |
|
`response_model`, converting any data as necessary to generate the |
|
corresponding JSON. But if the data in the object returned is not |
|
valid, that would mean a violation of the contract with the client, |
|
so it's an error from the API developer. So, FastAPI will raise an |
|
error and return a 500 error code (Internal Server Error). |

(fields) defined in the `response_model`. If you returned an object |

that contains an attribute `password` but the `response_model` does |

not include that field, the JSON sent to the client would not have |

* Validation: whatever you return will be serialized with the |

valid, that would mean a violation of the contract with the client, |
