django ORM: get all the fields of model with positive value in one field

Question

I am trying to query all the objects in a model that have a positive value in one particular field.

I have not been able to find anywhere whether there is a way to use greater than signs in django. I have tried doing by sorting the column that interests me and removing the 0 values in that column in order to the overcome the greater than. First it seems over complicated, and second it does not work.

here is the query:

count_orders = replenishment.objects.order_by(F('StockOnOrder')).desc().exclude('StockOnOrder' = 0)

I also need to count the positive rows in this field and it does not work either as following:

count_orders = replenishment.objects.order_by(F('StockOnOrder')).desc().exclude('StockOnOrder' = 0).count()

both give me the error:

keyword can't be an expression

I am wondering if by chance this is the proper way to do it, or if there is something more intuitive and simple.

Answer 1

你应该使用 gt。

model.objects.filter(your_field__gt=0)
