Then we create a new `Hero` (this is the actual **table** model that saves things to the database) using `Hero.model_validate()`.
The method `.from_orm()` reads data from another object with attributes and creates a new instance of this class, in this case `Hero`.
The method `.model_validate()` reads data from another object with attributes (or a dict) and creates a new instance of this class, in this case `Hero`.
The alternative is `Hero.parse_obj()` that reads data from a dictionary.
In this case, we have a `HeroCreate` instance in the `hero` variable. This is an object with attributes, so we use `.model_validate()` to read those attributes.
But as in this case, we have a `HeroCreate` instance in the `hero` variable. This is an object with attributes, so we use `.from_orm()` to read those attributes.
/// tip
In versions of **SQLModel** before `0.0.14` you would use the method `.from_orm()`, but it is now deprecated and you should use `.model_validate()` instead.

With this, we create a new `Hero` instance (the one for the database) and put it in the variable `db_hero` from the data in the `hero` variable that is the `HeroCreate` instance we received from the request.
We can now create a new `Hero` instance (the one for the database) and put it in the variable `db_hero` from the data in the `hero` variable that is the `HeroCreate` instance we received from the request.
