Question

I want to filter my model object using two filters.
So, it can be only one filter or both or none.
My solution is to use a lot of ‘if’:

if _topic or _curator:
    if _topic and _curator:
        queryset = Article.objects.filter(topic=_topic,curator=_curator)
    elif _curator:
        queryset = Article.objects.filter(curator=_curator)
    else # so topic is the last choice
        queryset = Article.objects.filter(topic=_topic)
else
    queryset = Article.objects.all()

Can someone suggest an easier way to filter?

Answer 1

Queryset filters are cumulative.

queryset = Article.objects.all()
if _topic:
    queryset = queryset.filter(topic=_topic)
if _curator:
    queryset = queryset.filter(curator=_curator)
