Example Code

from typing import Optional
from sqlmodel import SQLModel, Field

class Company(SQLModel, table=True):
    __tablename__ = "Company"  # type: ignore
    id: Optional[int] = Field(primary_key=True)
    name: str = Field(max_length=100)

c = Company(name="a" * 101)
print(c.name)
print(type(c.name))
c = Company(name="a" * 100)
print(c.name)
print(len(c.name))

Description

I have created a SQLModel with a string column and max_length constraint. If I add a value greater than the max_length constraint, instead of raising a validation error, the value is being set as None which isn't the desired behaviour, I have tried persisting the row to the db and I get an empty value there too (check third value).
