Security concerns with user defined postgres jsonb queries in Django
We have a postgres jsonb field in Django that allows users to store arbitrary user data. We wish to allow users to query this field but are unsure about the security implications. The model from django.db import models class Item(models.Model): user = models.ForeignKey("user", null=False) meta = JSONField() Query def custom_query(operation, value): qs = Item.objects.filter(user=user) params = { "meta__" + operation: value } qs = qs.filter(**params) Usage: Assuming meta is {"a": 1}. custom_query(operation="contains", value={"a": 1}) custom_query(operation="a", value=1) The above should be valid and equivalent queries. Is this a secure way to perform the query? -
Not able to pass user in a view in django so want to pass it through the URL
I am having a payment app in django(paytm) it has the following views: def payingpage(request): if request.user.is_authenticated: customer=request.user.customer order, created=Order.objects.get_or_create(customer=customer, complete=False) items=order.orderitem_set.all() shippingddress=ShippingAddress.objects.filter(customer=customer) total=order.finalpay() context={ 'items':items, 'order':order, 'ship':shippingddress } param_dict = { 'MID': 'QEnNqO51999030615507', 'ORDER_ID':str(order.id), 'TXN_AMOUNT':str(total), 'CUST_ID': "customer.user.id", 'INDUSTRY_TYPE_ID': 'Retail', 'WEBSITE': 'WEBSTAGING', 'CHANNEL_ID': 'WEB', 'CALLBACK_URL':'http://127.0.0.1:8000/handlerequest/', } param_dict['CHECKSUMHASH'] = Checksum.generate_checksum(param_dict,MERCHANT_KEY) return render(request, 'paytm.html', {'param_dict': param_dict}) return HttpResponse("ERROR") @csrf_exempt def handlerequest(request): form = request.POST response_dict = {} for i in form.keys(): response_dict[i] = form[i] if i == 'CHECKSUMHASH': checksum = form[i] verify = Checksum.verify_checksum(response_dict, MERCHANT_KEY, checksum) if verify: if response_dict['RESPCODE'] == '01': print('order successful') else: print('order was not successful because' + response_dict['RESPMSG']) return render(request, 'handlerequest.html', {'response': response_dict,'types':Category.objects.all()}) Now the problem is that I cant pass user=request.user or order=Order.objects.all(user=user) in handlerequest view as for some reason it is not working and what I want is that in some way I can get the order id in the handlerequest view so that I can set that the orders payment in successful but I am not able to that. In django docs i saw passing parameters through Url but I cannot figure out how to proceed with it (am a beginner).

How to speed up API calls?
What i'm trying to do: Get nationality of artists (which are basically the top artists of a particular user on Spotify) from MusicBrainz API. Purpose is to map each artist to his/her nationality What i've done so far : I'm using Django to build the web app, and so i'm making API calls to Spotify, retrieve artists, and then passing artist name in the search query with limit = 1 (as i really just want to select the first result) Problem: I see that in my web app, as you can see i'm making calls to Spotify API and then the MusicBrainz API (in the given order), the response i get from Musicbrainz API takes really long time hence the first page takes quite long to load up. Is there any way to speed up this process? Or open to take up suggestions that'd replace MusicBrainz API Here's my code: url = 'https://api.spotify.com/v1/me/top/artists' headers = {"Authorization": f"Bearer {socialtoken.token}"} params = {'time_range': 'short_term', 'limit': 50} resp = requests.get(url, headers=headers, params= params) response = resp.json() topArtists = {} //creates a dictionary of top artists with key = artists name and value set to None for i in range(len(response['items'])): topArtists[(response['items'][i]['name'])] = None // … -

Is there a way to get django-dashing work with newer versions of django?

Fail to display the context passed to templates while using Django3.1
