from .models import Article
nl_filter = DjangoNLFilter()
qs = Article.objects.all()
q = 'author.username is john or title contains news'
# equivalent to Article.objects.filter(Q(author__username="user") | Q(title__icontains="news"))
articles = nl_filter.filter(qs, q)
# Nested logical operators are also supported:
q = 'author.username is john and (title contains news or created_at <= 2020-06-05)'
# equivalent to
# Article.objects.filter(
# Q(author__username="user") & (Q(title__icontains="news") | Q(created_at__lte="2020-06-05"))
# )
articles = nl_filter.filter(qs, q)
