I’m building a simple API listing various plants. Currently, it’s limited to filter via a single field like common name, species, etc.
My urls.py
urlpatterns = [
path('project/family=<str:family>/', views.SpeciesDetail_family.as_view(), name='family'),
path('project/species=<str:species>/', views.SpeciesDetail_species.as_view(), name='species')
]
And views.py
class SpeciesDetail_species(generics.ListAPIView):
serializer_class = SpeciesSerializer
def get_queryset(self):
queryset = Species.objects.filter()
species = self.kwargs['species']
if species is not None:
queryset = queryset.filter(species__iexact=species)
return queryset
class SpeciesDetail_family(generics.ListAPIView):
serializer_class = SpeciesSerializer
def get_queryset(self):
queryset = Species.objects.all()
family = self.kwargs['family']
if family is not None:
queryset = queryset.filter(family__iexact=family)
return queryset
How can I create a single view for these two paths? So, I just need to parameterize the lookup field (can be family, species, etc.) from the URL like /project/species=PlantSpecies/ or /project/family=PlantFamily/.
If I add kwargs to the path like path('project/family=<str:family>/', views.SpeciesDetail_family.as_view(), {'lu_field':'family'}, name='family'), how can I access lu_field in the views?
Take a look at the code below see if it works the way you want :
from rest_framework import generics
from .models import Species
from .serializers import SpeciesSerializer
class SpeciesDetail(generics.ListAPIView):
serializer_class = SpeciesSerializer
def get_queryset(self):
queryset = Species.objects.all()
# Access dynamic lookup field and value from kwargs
lu_field = self.kwargs.get('lu_field')
lu_value = self.kwargs.get('lu_value')
# Filter the queryset dynamically
if lu_field and lu_value:
filter_kwargs = {f"{lu_field}__iexact": lu_value}
queryset = queryset.filter(**filter_kwargs)
return queryset
and here is the urls:
from django.urls import path
from . import views
urlpatterns = [
path('project/<str:lu_field>=<str:lu_value>/', views.SpeciesDetail.as_view(), name='species_detail'),
]
