Ormar (async)

When generating routes, the OrmarCRUDRouter will automatically tie into your database using your ormar models. To use it, simply pass your ormar database model as the schema.

Simple Example

Below is an example assuming that you have already imported and created all the required models.

from fastapi_crudrouter import OrmarCRUDRouter
from fastapi import FastAPI

app = FastAPI()

router = OrmarCRUDRouter(
    schema=MyOrmarModel,
    create_schema=Optional[MyPydanticCreateModel],
    update_schema=Optional[MyPydanticUpdateModel]
)

app.include_router(router)

Note

The create_schema should not include the primary id field as this be generated by the database.

Full Example

# example.py
import databases
import ormar
import sqlalchemy
import uvicorn
from fastapi import FastAPI

from fastapi_crudrouter import OrmarCRUDRouter

DATABASE_URL = "sqlite:///./test.db"
database = databases.Database(DATABASE_URL)
metadata = sqlalchemy.MetaData()

app = FastAPI()


@app.on_event("startup")
async def startup():
    await database.connect()


@app.on_event("shutdown")
async def shutdown():
    await database.disconnect()


class BaseMeta(ormar.ModelMeta):
    metadata = metadata
    database = database


def _setup_database():
    # if you do not have the database run this once
    engine = sqlalchemy.create_engine(DATABASE_URL)
    metadata.drop_all(engine)
    metadata.create_all(engine)
    return engine, database


class Potato(ormar.Model):
    class Meta(BaseMeta):
        pass

    id = ormar.Integer(primary_key=True)
    thickness = ormar.Float()
    mass = ormar.Float()
    color = ormar.String(max_length=255)
    type = ormar.String(max_length=255)


app.include_router(
    OrmarCRUDRouter(
        schema=Potato,
        prefix="potato",
    )
)

if __name__ == "__main__":
    uvicorn.run("example:app", host="127.0.0.1", port=5000, log_level="info")
