Hello everyone, hope you're all doing well.
I have a table which has a type column. Based on that value I need to
instantiate a new class. I'm looking for a way to operate my SQLAlchemy
object through this new class.
Here's my model class:
```
class AnimalModel(Base):
__tablename__ = "animal"
id = Column(Integer, primary_key=True)
type = Column(String)
name = Column(String)
...
```
Here is my python class.
```
class Mammal(BaseAnimal):
def __init__(self, animal_model):
self.__dict__.update(animal_model.__dict__)
def has_fur(self):
return True
```
Once I query the animal table and receive the `AnimalModel` object. I
create a new `BaseAnimal` class based on the type.
I need a way to merge or remap the `AnimalModel` object to the new
`BaseAnimal` object so that I can get my methods from `BaseAnimal` and I
also get to do table updates.
```
mammal = new Mammal(animal_model)
mammal.has_fur()
mammal.name = 'Whale' # SQL row update
```
What are some ways in which this can be achieved?
