Question

Is there a way to use an expression in django filter function like a key.

I am trying to do this:

models.Product.objects.filter("name_cn" = "smth")

and get an error:

SyntaxError: keyword can't be an expression

Answer 1

If name_cn is a variable, then put it in a dictionary, and deliver the keyword arguments in your dictionary using the ** operator:

models.Product.objects.filter(**{name_cn: "smth"})

If "name_cn" is the name of the field you want to filter on, then try:

models.Product.objects.filter(name_cn="smth")
