How to make an API call to another one of my views? - django

Question

I am working on a simple investment-tracker app, which should get stock prices from an api and display them nicely for the user. I am having trouble, however to pass the necessary data through to the API call.
views.py
class PortfolioData(APIView):
authentication_classes = []
permission_classes = []
def get(self, request, tickers ,format=None):
# how do I pass the tickers?
stock_data = get_multiple_stock_details(tickers) # returns JSON response
return Response(stock_data)
#login_required
def portfolio(request):
user = request.user
user_portfolio = Portfolio.objects.filter(user=user).first()
return render(request, 'app/portfolio.html', {'portfolio':user_portfolio})
urls.py
urlpatterns = [
path('', views.home, name="homepage"),
path('api/portfolio/data/', views.PortfolioData.as_view(),
name="portfolio-data"),
path('portfolio/', views.portfolio, name='portfolio'),
]
On the frontend I would make an ajax call to my PortfolioData view, in order to be able to process the data on the frontend. My biggest issue is how to pass the needed parameters.
I tried to get the ticker symbols from the frontend using jQuery and then pass that to the endpoint url but I am not sure if this is the best way to go about this.

You can try something like this,,,
urls.py
'''
You should bind two different url with same view. One with dynamic variable and another without it.
'''
urlpatterns = [
path('', views.home, name="homepage"),
path('api/portfolio/', views.PortfolioData.as_view(), name='api_portfolio'), # use unique name for each URL
path('api/portfolio/<tickers>/', views.PortfolioData.as_view(), name='api_portfolio_data'), # use unique name for each URL
path('portfolio/', views.portfolio, name='portfolio'),
]
views.py
class PortfolioData(APIView):
authentication_classes = []
permission_classes = []
def get(self, request, tickers=None ,format=None):
if tickers is None:
# GET /api/portfolio/
print('No tickers parameter in URL')
# implement your logic when tickers is not passed.
return Response(JSON_DATA)
# GET /api/portfolio/tickers1/
# implement your logic when tickers is passed.
stock_data = get_multiple_stock_details(tickers) # returns JSON response
return Response(stock_data)
Now, when make HTTP GET request (Does not matter, it's AJAX call or not).
http://localhost:8000/api/portfolio/
tickers variable will be None this case.
http://localhost:8000/api/portfolio/ticker1/
tickers variable will be ticker1 str this case.
Hope, it helps you.
