I’m using SQLModel with Alembic for database migrations in my project. However, Alembic doesn’t seem to recognize my models and creates empty migrations.

Here’s the code for my model:

from sqlmodel import Field, SQLModel
from app.model.base_model import BaseModel

class UserType(Enum):
    buyer = "buyer"
    seller = "seller"

class User(BaseModel):
    user_id: int = Field(default=None, primary_key=True, index=True)
    role: UserType = Field(default="buyer")
    name: str = Field(default=None)
    email: str = Field(default=None)
    description: str = Field(default=None)
    password_hash: str = Field(default=None)
    profile_picture: str = Field(default=None)

In my env.py file, I’m importing the models like this:
from app import model # noqa(import from init.py)
And I’ve set the target_metadata to SQLModel.metadata:
target_metadata = SQLModel.metadata

Despite this, when I run alembic revision –autogenerate, it creates an empty migration file with upgrade() and downgrade() functions that just contain pass.

I’ve followed the documentation closely, but I can’t figure out why Alembic isn’t recognizing my models. Any help would be greatly appreciated.
