Hi @lovetoburnswhen !

I am facing the problem mentioned in this issue and #1042 I am trying to achieve camelCase schema generation for FastAPI.

So far I have tried to manually set config attributes like below with no luck so far:

from humps import camelize
from src.db.models import Plan

def to_camel(field_name):
    return camelize(field_name)

PdPlan = pydantic_model_creator(Plan, name="PdPlan")

setattr(PdPlan.Config, "alias_generator", to_camel)
setattr(PdPlan.Config, "allow_population_by_field_name", True)

PdPlan.schema()

It looks like fields are set. But .schema() method still display snake_case fields.

May I ask how you managed to set config attributes afterwards of model creation as you mentioned above?

Edit: I ended up implementing something like this:

from humps import camelize
from pydantic import Base Model
from src.db.models import Plan

def to_camel(field_name):
    return camelize(field_name)

__PdPlan = pydantic_model_creator(Plan, name="PdPlan")

class __PydanticConfig:
    orm_mode = True
    alias_generator = to_camel
    allow_population_by_field_name= True

class PdPlan(__PdPlan):
    class Config(__PydanticConfig):
        pass

It's not perfect, but at least it solved my problem for this time. Anyone stuck with same problem may use until this #1048 arrives.
