How do I create a new ORM object with information passed via JSON?

I have an ORM class created with SQLAlchemy, example:

```
class Person(Base):
name = Column(String,nullable=False)
birthdate = Column(String,CheckConstraint("birthdate >= '1970-01-01'")
ssn = Column(String,primary_key=True)
```

My Flask app will be in charge of retrieving and inserting ORM objects like so:

```
@app.route("/people//insert",methods=["PUT"])
def insert_person(ssn):
# insert person into database
```

The information to be inserted will be provided within the request, via a JSON string, ex:
```{"name":"Bobby Burger","ssn":"123-45-6789"}```
I already have a schema defined that I won't mention here.

I want to create an ORM object filled with the information provided.
How do I do this?

The issue mentions a Flask route, a SQLAlchemy ORM class, and an existing schema, but names no repository file or test. Start by locating the project’s request-validation and ORM usage documentation; done would be a clear, project-specific example covering JSON input and object creation.
