REQUEST certain Elements in Django POST API from User - django

Question

I want to Request a dictionary like
{
"username": "a",
"password": "b",
"year": "2019-20",
"start": 1,
"end": 2,
"reference_id": "two"
}
from a user so that a user can hit the API and get the desired result.
My view looks like
def post(self,request, *args, **kwargs):
# self.http_method_names.append("post")
user = request.POST.get("user")
pasd = request.POST.get("pasd")
year = request.POST.get("year")
start = request.POST.get("start")
end = request.POST.get("end")
reference_id = request.POST.get("reference_id")
#Passing the parameters to another function to get the result.
status = main_function(user=user,pasd=pasd,year=year,start=start,end=end,reference_id=reference_id)
return Response(status)
Now the problem when I'm posting something in Django like
I'm getting None in every field. Ideally, I should get the values passed in the Dictionary.
Can someone please help me here.

Answer 1

In django rest framework, you should use request.data instead of request.POST, as it requires parser to receive JSON data. More info can be found in drf docs.
Change your code to:
def post(self,request, *args, **kwargs):
# self.http_method_names.append("post")
user = request.data.get("username") # <-- this used incorrect key
pasd = request.data.get("password") # <-- this used incorrect key
year = request.data.get("year")
start = request.data.get("start")
end = request.data.get("end")
reference_id = request.data.get("reference_id")
#Passing the parameters to another function to get the result.
status = main_function(user=user,pasd=pasd,year=year,start=start,end=end,reference_id=reference_id)
return Response(status)

I Got The Answer. SO if You Want to take input from a user then You should write this in your views.py file.
But First you have to tell Django Which Fields input you want. So you have to create a serializer.py file in the Django APP.
from rest_framework import serializers
class userdetailSerializer(serializers.Serializer):
username = serializers.CharField(max_length=20)
password = serializers.CharField(max_length=20)
year = serializers.CharField(max_length=8)
start = serializers.IntegerField()
end = serializers.IntegerField()
reference_id = serializers.CharField(max_length=50)
I need all the Above values from the User that's why i have added all. If you want Only certain values you can delete it from your serializer file.
After this goto your Views.py file and get the response entered by user using below code.
Serializer will autovalidate the input and if the input is not correct it will give a dictionary of error(In else Statement)
def post(self,request, *args, **kwargs):
# self.http_method_names.append("post")
serializer = self.serializer_class(data=request.data)
if serializer.is_valid():
username = serializer.validated_data.get('username')
password = serializer.validated_data.get('password')
year = serializer.validated_data.get('year')
start = serializer.validated_data.get('start')
end = serializer.validated_data.get('end')
reference_id = serializer.validated_data.get('reference_id')
response_status = main_function(user=username, pasd=password,year=year,start=start,end=end,reference_id=reference_id)
return Response("The File Upload Response Will Come HEre",response_status)
# return Response({'name':username, 'pass':password,'year':year,'start':start,'end':end,'reference_id':reference_id})
else:
return Response(serializer.errors)
The POST API will LOOk Like this.
