FastAPI RuntimeError: Use params or add_pagination - fastapi

Question

I'm writing my second project on FastAPI. And I got this error.
For example I have this code in my routers.users.py:
#router.get('/', response_model=Page[Users])
async def get_all_users(db: Session = Depends(get_db)):
return paginate(db.query(models.User).order_by(models.User.id))
And it works. It has fields limit and page in swagger documentation.
I tried to write the same for routers.recipes.py, but in this case I have no fields for pagination(limit, page) in swagger. Ok, I googled and found out that adding dependencies could help me. And now I see pagination parameters in swagger, but error is still the same.
routers.recipes:
#router.get('/', response_model=Page[PostRecipes], dependencies=[Depends(Params)])
async def get_all_recipes(db: Session = Depends(get_db)):
return paginate(db.query(models.Recipe).order_by(models.Recipe.id))
pagination:
class Params(BaseModel, AbstractParams):
page: int = Query(1, ge=1, description="Page number")
limit: int = Query(50, ge=1, le=100, description="Page size")
def to_raw_params(self) -> RawParams:
return RawParams(
limit=self.limit,
offset=self.limit * (self.page - 1),
)
class Page(BasePage[T], Generic[T]):
page: conint(ge=1) # type: ignore
limit: conint(ge=1) # type: ignore
__params_type__ = Params
#classmethod
def create(
cls,
items: Sequence[T],
total: int,
params: AbstractParams,
) -> Page[T]:
if not isinstance(params, Params):
raise ValueError("Page should be used with Params")
return cls(
total=total,
items=items,
page=params.page,
limit=params.limit,
)
__all__ = [
"Params",
"Page",
]
So, does anyone have ideas about it?

Answer 1

according to doc you have to specify default parameters,
your code should look like paginate(iterable, params)
