Why do we need response_model?

[aklauza]

Why doesn´t FastAPI use python hints for returning types as well?

This code is more intuitive

@app.post("/items/")
async def create_item(item: Item) -> Item:
    return item

than this

@app.post("/items/", response_model=Item)
async def create_item(item: Item):
    return item

Please do a search here first. Possible duplicate of #875.

And here as well: #620. I think many people are asking about it because it makes lots of sense. I actually see as the most common scenario to return the model itself as is, rather than a special "serialization model" with different fields.
