Azure AD User access token requested by angular MSAL library and validation by WEB API using django_auth_adfs
I am playing to setup an Angular Single Page Application using MS MSAL Angular library to request an Access token to get user details from Microsoft Graph API and to authenticate into a custom WEB API build with DJango Python Framework. I use the django_auth_adfs and rest_framework libraries to build this API. I used the following tutorials to setup my environments : https://docs.microsoft.com/en-US/azure/active-directory/develop/tutorial-v2-angular-auth-code and https://azuread.github.io/microsoft-authentication-library-for-js/ref/msal-angular/ for the Angular Side https://django-auth-adfs.readthedocs.io/en/latest/rest_framework.html for the DJango side In my Angular App, I am able to login with my Azure AD credential. I can see that the access tokens for MS Graph and for my API are well fetched but this last is not accepted by my WEB API. On Azure AD, I setup the two applications. One for the Angular frontend and one for the django backend. Here are my configurations: For DJango backend: Authentication using Web configuration with redirect URI to http://localhost:8000/oauth2/callback and only organizational directory accounts (no implicit flow). Tried without and with a client secret (same result). No token configuration Permissions to MS Ggaph without admin consent required and granted for my organization as status. Scope defined to expose the API: api://xxxxxxxx-32d5-4175-9b05-xxxxxxxxxxxx/access_as_user (Admins and Users consent enabled) and my frontend … -
Efficiently get first and last model instances in Django Model with timestamp, by day
Suppose you have this model: from django import models from django.contrib.postgres.indexes import BrinIndex class MyModel(model.Models): device_id = models.IntegerField() timestamp = models.DateTimeField(auto_now_add=True) my_value = models.FloatField() class Meta: indexes = (BrinIndex(fields=['timestamp']),) There is a periodic process that creates an instance of this model every 2 minutes or so. This process is supposed to run for years, with multiple devices, so this table will contain a great number of records. My goal is, for each day when there are records, to get the first and last records in that day. So far, what I could come up with is this: from django.db.models import Min, Max results = [] device_id = 1 # Could be other device id, of course, but 1 for illustration's sake # This will get me a list of dictionaries that have first and last fields # with the desired timestamps, but not the field my_value for them. first_last = MyModel.objects.filter(device_id=device_id).values('timestamp__date')\ .annotate(first=Min('timestamp__date'),last=Max('timestamp__date')) # So now I have to iterate over that list to get the instances/values for f in first_last: first = f['first'] last = f['last'] first_value = MyModel.objects.get(device=device, timestmap=first).my_value last_value = MyModel.objects.get(device=device, timestamp=last).my_value results.append({ 'first': first, 'last': last, 'first_value': first_value, 'last_value': last_value, }) # Do something with results[] This … -
