Calling a function name inside a function in Django Rest Framework - django

Question

I have tried to call the two method inside the function where I couldn't able to call those method. I have tried few approaches but not succeeded. Here, What I have tried
"UserStartShift", "UserStopShift" are the API functions which have GET and POST method in it. These API are working fine individually, I wanted to return a different response using the conditional statement.
views.py:
# startshift
#api_view(['GET'])
def UserStartShift(request):
if request.method == 'POST':
UserId = request.data.get('UserId')
Ip = request.data.get('Ip')
PortNumber = request.data.get('PortNumber')
print("UserId-->", UserId)
print("Ip-->", Ip)
print('Portnumber-->', PortNumber)
cursor = connection.cursor()
cursor.execute('EXEC [dbo].[Usp_StartShift] #UserId=%s, #IP=%s, #Port=%s', (UserId, Ip, PortNumber,))
return Response(True, status=status.HTTP_200_OK)
# endshift
#api_view(['GET'])
def UserStopShift(request, UserId):
try:
users = tblUserShiftDetails.objects.filter(UserId=UserId)
except tblUserShiftDetails.DoesNotExist:
return Response(status=status.HTTP_404_NOT_FOUND)
if request.method == 'GET':
cursor = connection.cursor()
cursor.execute('EXEC [dbo].[USP_StopShift] #UserId=%s',(UserId,))
return Response(True)
#UserShiftDetailsView
#api_view(['GET'])
def UserShiftDetailsView(request, userid):
try:
users = tblUserShiftDetails.objects.filter(UserId=userid)
except tblUserShiftDetails.DoesNotExist:
return Response(status=status.HTTP_404_NOT_FOUND)
if request.method == 'GET':
if UserStartShift == True:
cursor = connection.cursor()
cursor.execute('EXEC [dbo].[USP_GetCurrentShiftDetails] #UserId=%s',(userid,))
result_set = cursor.fetchall()
for row in result_set:
row = row[0]
return Response({"IsStarted":True,"EstimatedShifEnd":(row + datetime.timedelta(hours=9)).strftime('%d-%m-%Y %H:%M %p'),"ReasonforAccess": "null"})
elif UserStopShift == True :
cursor = connection.cursor()
cursor.execute('EXEC [dbo].[USP_GetCurrentShiftDetails] #UserId=%s',(userid,))
result_set = cursor.fetchall()
for row in result_set:
row = row[0]
return Response({"IsStarted":False,"EstimatedShifEnd":"null","ReasonforAccess": "null"})
