Validate pydantic field against a list of values

Question

I would like to query the Meals database table to obtain a list of meals (i.e. 1= breakfast, 2= lunch, 3= dinner, etc.), and validate the Recipe meal_id contains one of these values. Is this possible? Any suggestions how?

# Models

class Meal(Base):
    __tablename__ = "meals"

    id = Column(Integer, primary_key=True, index=True)
    name = Column(String, index=True, unique=True)

class Recipe(Base):
    __tablename__ = "recipes"

    id = Column(Integer, primary_key=True, index=True)
    name = Column(String, index=True)
    note = Column(String, nullable=True)
    star = Column(Boolean, default=False)
    meal_id = Column(Integer, ForeignKey("meals.id"), nullable=True)
    details = relationship("RecipeIngredient")
    owner_id = Column(Integer, ForeignKey("users.id"))

# Schemas

class Meal(BaseModel):
    name: str

class Recipe(BaseModel):
    name: str
    note: Optional[str] = None
    star: Optional[bool] = False
    meal_id : Optional[str] = None
