The view core.views.postcodes didn't return an HttpResponse object. It returned None instead












0















I want to render a local json file I'm loading from a view in Django.



I have this function on my views.py file:



def postcodes(request):
data = open('core/stores.json').read()
jsonData = json.loads(data)


On my urls.py:



urlpatterns = [
path('stores/', views.postcodes, name='postcodes'),
]


It throws me this error:



Internal Server Error: /stores/
Traceback (most recent call last):
File "/home/kristian/.virtualenvs/rest_tails2/lib/python3.6/site-packages/django/core/handlers/exception.py", line 35, in inner
response = get_response(request)
File "/home/kristian/.virtualenvs/rest_tails2/lib/python3.6/site-packages/django/core/handlers/base.py", line 139, in _get_response
"returned None instead." % (callback.__module__, view_name)
ValueError: The view core.views.postcodes didn't return an HttpResponse object. It returned None instead.


I think this comes from the fact that I'm using request as a parameter on my postcodes function.



Any ideas on how can I load this json file on my view?



I'm using Django 1.11

    Your postcodes view does not return something, it should return a HttpResponse object.

    Note that all of this is pointless. There is no reason to parse the JSON to Python if all you want to do is to send it to the browser. This is a static file and should be handled by the static file serving system, just like your JS and CSS.

Well here you do not return anything, the function is called, but it does not, as expected, returns a HttpResonse.



Based on your view, you probably want to return a JsonResponse [Django-doc], so we can return this with:



from django.http import JsonResponse
import json

def postcodes(request):
with open('core/stores.json') as f:
data = json.load(f)
return JsonResponse(data)


If you however do not plan to do any filtering, aggregation, or other processing, you however better move the stores.json to a static file, like @DanielRoseman says.
