使用fastapi-contrib的FastApi分页错误 [英] FastApi pagination error using fastapi-contrib

问题描述

我正在尝试将分页添加到我的fastapi项目中.所以我决定使用这个:

I'm trying to add pagination to my fastapi project. So I decide to use this:

fastapi-contrib

我在那儿遵循相同的示例，但是由于某种原因，我遇到了这个错误:

I follow the same example there, but for some reason I'm getting this error:

type object 'MOrdenesTrabajo' has no attribute 'count'

这是我的代码，谢谢您的帮助！

Here is my code, thanks for your help!!

路线

@router.get("/ordenes-trabajo")
async def read_ot(pagination: Pagination = Depends(), db: Session =Depends(get_db)):
   filter_kwargs = {}
  return await pagination.paginate(serializer_class=OtSerializer.MOrdenesTrabajo, **filter_kwargs)

热缩模型

class MOrdenesTrabajo(ModelSerializer):

   class Meta:
    model = OT # <---Model below

Sqlalchemy模型

class MOrdenesTrabajo(Base):
__tablename__ = 'M_ordenesTrabajos'

idordenesTrabajos = Column(Integer, primary_key=True)
fecCreacion = Column(Date)
fecModificacion = Column(Date)
estado = Column(Integer)
descripcion = Column(Text)
nombre = Column(String(100))
documento = Column(Text)
fechaOrden = Column(Date)
numero = Column(Text)
ot_padre = Column(Integer)
data = Column(JSON)

推荐答案

我认为您应该使用 sqlalchemy-过滤器.我在FastAPI项目中使用它进行分页，它按预期工作.我的分页代码如下:

I think you should use sqlalchemy-filters. I am using it for pagination in my FastAPI project and it works as expected. My code for pagination looks like this:

# pagination
num_of_pages = 0
total_results = 0
if skip and limit:
    results, pagination = apply_pagination(
         results,
         page_number=skip,
         page_size=limit
    )
    num_of_pages = pagination.num_pages
    total_results = pagination.total_results
