Django REST API without using Database

Question

I have an existing Django application. I need to include a functionality in it which doesn't involve DB. I have written the operation to be performed in views.py

 class VamComponent(View):
    def getSectionADetails(self,request):
     .......
    return HttpResponse()

In urls.py I have included this line in urlpatterens:

url(r'^vamcomponent$', VamComponent.as_view())

I am able to access the details from this url http://localhost:8000/vamcomponent/ .

I need to have my endpoints with some value for section in the url like http://localhost:8000/vamcomponent/SectionA and http://localhost:8000/vamcomponent/SectionB.

In views.py if I modify the class to have 2 functions it,based on the value of section in the request it should call the respective method

 class VamComponent(View):
    def getSectionADetails(self,request):
     .......
    return HttpResponse()
    def getSectionBDetails(self,request):
     .......
    return HttpResponse()

How to make this change in urls.py file so that getSectionADetails() is called when the request has SectionA in it else getSectionBDetails()?

I think you can try like this:

First, you need to update the view so that it accepts a new parameter, ie SectionA or SectionB # urls

url(r'^vamcomponent/(?P<section>[-\w]+)/?$', VamComponent.as_view())

Now lets update the view accordingly, so that the value passed in urls goes to the view:

class VamComponent(View):
     def get(self, request, section=None):  # or post if necessary
         if section == "SectionB":
            return self.getSectionBDetails(request)
         return self.getSectionADetails(request)

FYI, if you are using django-rest-framework, then why don't you use APIView:

from rest_framework.views import APIView

class VamComponent(APIView):
    # rest of the code

If I use APIView, do I need to use the same url patterns as I do the View?

@Jayashree Yes, also it will allow you to use some functionalities such as permissions_classes,authentication_classes etc. More information are provided in documentation(attached with the answer)
