pass query param as dictionary with many values in postman - django

Question

I am using postman to hit my APIs. I have a question regarding sending query params through postman params. In my API i am getting params using services = request.GET.get('services') and then returning response for the services.
My Question is if have more than one service like 'A', 'B', 'C', then how can we send these services in params using postman?
views.py
class SomeAPIView(ModelViewSet):
def get_queryset(self):
services = self.request.GET.get('services')
print(services) # getting services
print(type(services)) #type is string
response_list = []
for service in services:
result = API(service=service)
response_list.append(result)
return response_list
I want get list of services and then iterate over that list to return response for that service.

It depending on how you would use this API entry in production.
At first, the good way in django is to use request.query_params to obtain query parameters. Also you must provide default value to get() method to avoid exceptions if there's no 'services' parameter passed.
Then, if your services parameter contain names or ids of some objects, you may just pass it with parameters in GET request as http://someurl?services=A,B,C, or within tab, named 'Params' in postman. So request.query_params.get('sevices', '') will return string, contains 'A,B,C'. Now you can split it by ',' like services_names = str.split(',').
Anyway, parameters of GET requests may return only str values.
According to your example, it may looks like:
class SomeAPIView(ModelViewSet):
def get_queryset(self):
services = self.request.query_params.get('sevices', '').split(',')
print(services) # getting services
print(type(services)) # now it will be List[str]
response_list = []
for service in services:
result = API(service=service)
response_list.append(result)
return response_list
