Access sqlalchemy relationship from 2 related tables

[Master-Y0da]

Hi, I'm new at using fastapi...and I want to know if is possible to access a pydantic relationship in a reverse way ?. Like this.

SqlAlchemy models:

       class t1(Base):
          idpruebas = Column(Integer, primary_key=True)

      class t2(Base):
          idreglas = Column(Integer, primary_key=True)

           M_prueba = relationship('t1')

so if I want to create a pydantic schema for t1 class, is there a way of doing that and append the t2 class accesing the relationship name??.

  class t1pydantic(BaseModel): 
      idpruebas: int
      some: # Append the t2 here

     class Config:
     orm_mode = True

Thank you for your help and excuse my english

Man, if you want people to help you, try to follow our template and organize your code.
If you use the following github tool (you can see it when you are writing), you can insert code inside and we are able to read it:

Thanks for the help @Kludex ! 🙇 ☕

@lvar you would need a Pydantic model for each SQLAlchemy model, alone, without relationships. You could use pydantic-sqlalchemy for that as @Kludex mentions.

Then you could probably create subclasses of those Pydantic models adding the relationships that you want to show.
