Supporting geoalchemy2 #74

Open neatek opened 1 month ago

neatek commented 1 month ago

The issue arises when using a column with the type Geometry("POINT") from geoalchemy2, as attempting to utilize FastCRUD results in an error: 'utf-8' codec can't decode byte 0xe6 in position 5: invalid continuation byte. It would be beneficial to add support for geoalchemy2. If that's not feasible, is there an alternative approach for handling such a column type? Or is it necessary to write custom queries and routes? As always thank for you answer!

Are you talking about the crud methods or the endpoint creation functionalities? Could you please provide some code to reproduce?

Example:

CRUD (routes)

photo_location_crud = FastCRUD(models.PhotoLocation)
photo_location_router = crud_router(
    session=get_session,
    model=models.PhotoLocation,
    crud=photo_location_crud,
    path="/photos",
    tags=["Photos"],
    ...
)

SQLAlchemy Model

from geoalchemy2 import Geometry
class PhotoLocation(Base):
    __tablename__ = "photo_location"
    id = Column(BigInteger, primary_key=True, autoincrement=True)
    ...
    location = Column(
        Geometry("POINT"), nullable=True
    )

Then when I start using get_multi and stuff, it gets binary data by location (POINT), and can't output to get_multi or other routing. It is clear that to process absolutely all possible binary data in the database is almost impossible, probably, but to make support for a point for example I think it is possible.
