from rest_framwork.routers import SimpleRouter

inbuild methods with model viewset
def create() ===>POST

def retrieve() ==>GET
def list() ===>GET
def destroy() ==>DELETE
@action(methods=['post'],detail=True)

urls
from rest_framwork.routers import SimpleRouter
#main_url/function_name/
http://localhost:8000/student/
student is function name mapped to viewset function or class
student ===>StudentViewset
router=SimpleRouter()
router.register(r'student',StudentViewset)
urlpatterns=router.urls
ModelViewSet
class ModelViewSet(mixins.CreateModelMixin,==>POST create
mixins.RetrieveModelMixin, ==>GET, retrieve
mixins.UpdateModelMixin, ==>PUT,PATCH update
mixins.DestroyModelMixin,==>DELETE destroy
mixins.ListModelMixin, =====>GET, list
GenericViewSet)
class ProfileViewset(viewsets.ModelViewSet)
create
update
list retrieve
delete
class ProfileViewsets(mixins.CreateModelMixin,GenericViewSet)
def create() ===>POST
Admin
admin.site.register(Student)
or we can customize with adminModel
example to disable delete option from admin
class StudentModel(admin.ModelAdmin):
def get_actions(self, request):
actions = super(StudentModel, self).get_actions(request)
if 'delete_selected' in actions:
del actions['delete_selected']
return actions
def delete_model(self, request, obj):
return 0
def message_user(self, request, message, level = 30, extra_tags, fail_silently) :
message='delete not allowed'#you can give whatever messeage you want
return super().message_user(request, message, 40, extra_tags, fail_silently)
so then we can resgist Student model like
admin.site.register(Student,StudentModel)
to get more about this overiding functions alt+click on admin.ModelAdmin
