✅
print(data)
won’t work. You have to do something like:
return HttpResponse(data)
Then visit the URL of that view and you’ll see the result.
Update
MultiValueDictKeyError
occurs if the key that you’re trying to access is not in request.GET
or request.POST
.
To prevent this error, make sure your GET
request has zoom
key. For that you will need to write the URL in addressbar something like this:
/getmarkers/?zoom=val&formlat=val&somekey=val
Replace val
with the value for that key.
