如何使用fastapi和SQLAlchemy更新信息

Question

I am using FastAPI and SQLAlchemy. I have two ORM models users and user_profiles with foreign key relation. I am inserting data to user and user_profiles using one model

   #1st model.
  class User():
      __tablename__: str = "user"
   #2 Model
   class UserProfile:
      __tablename__: str = "user_profiles"
     

my user request model to update the data:

class UserRequest():
    user_id:str=someval()

My question is how I can include user_profiles model in UserRequest and update the values.

If by UserRequest you mean pydantic model, then it can be done something like this

DB Models

class User(sql.Model):
   a: str = Field()
   b: str = Field()
   properties: UserProperties = ForeignKey()

class UserProperties(sql.Model):
   c: str = Field()
   d: str = Field()

Pydantic models

class UserDTO(pydantic.BaseModel)
   a: str
   b: str

class UserPropertiesDTO(pydantic.BaseModel)
   c: str
   d: str

Then

def request(
   a: str,
   b: str,
   c: str,
   d: str,
) -> Response:
   User.objects.create(
      **UserDTO(a, b).dict(),
      properties=UserPropertiesDTO(c, d),
   )
   return SuccessfulResponse
