Best way to set up Django model for a balance sheet app
I want to create simple app where a user can keep track of their net worth over time. For example, the user could go in at the end of each month and input their balances for all of their assets and liabilities. The app would keep track of the data over time so it could be displayed as a graph. I'm trying to figure out how to set up my models for this. I think I need to have the balances as a separate class otherwise every time you wanted to add a new date you would have to update the model itself. Here's what I came up with. I'm interested if this is a good way to do this or if there is a cleaner way. class Asset(models.Model): name = models.CharField(max_length=30) description = models.TextField() class Liability(models.Model): name = models.CharField(max_length=30) description = models.TextField() linked_account = models.ForeignKey(Asset,null=True,blank=True) class Meta: verbose_name_plural = "Liabilities" class AssetBalance(models.Model): account = models.ForeignKey(Asset) date = models.DateField() balance = models.FloatField() class LiabilityBalance(models.Model): account = models.ForeignKey(Liability) date = models.DateField() balance = models.FloatField() -
How to use Postman to authenticate Google Login with dj_rest_auth
So I am following the official documentation for Google sign in with DjangoRestFramework using DJ Rest Auth (this link) I intend to authenticate with Postman Oauth2 (by following the guide and generating an Access Token) Postman is generating an access token successfully, but I cannot seem to use this authentication in my API calls. Please who knows which step I am missing - I want to handle everything in Postman. urls.py urlpatterns = [ path('', Home.as_view(), name='home'), path('admin/', admin.site.urls), path('accounts/', include(api_urls, namespace='api')), path('accounts/login/', GoogleLogin.as_view(), name='google_login'), path('accounts/', include('rest_framework.urls')), ] views.py class GoogleLogin(SocialLoginView): adapter_class = GoogleOAuth2Adapter callback_url = 'http://localhost:8080/accounts/google/login/callback/' client_class = OAuth2Client On calling an API endpoint, I get an invalid token error: If I however visit the Google Login view in my RestFramework UI (in my case http://localhost:8080/accounts/login), I get an endpoint to make a POST, and on making a POST request, a key is generated. Only this key (if used as a Bearer token) works in my API calls. How can I authenticate on Google, and make my API calls independent of the DRF UI? Callback URL has been configured on my Google Developer Client. PS: I feel the answer is in step 6 of the documentation, but I am … -
How to prevent methods of being imported in an outside package at pycharm?
I would like to prevent imports of private methods outside a specific interface in a big commercial project to improve architecture. I've tried with init.py but maintenance is hard and I had problems with circular imports over time. I've also tried with _method() underline to make private methods, but then I could not use these methods inside my own interface. What I would like to set up or within my pycharm configs or by making a customized use of import machinery from python is something like these: -- interface_foo ---- method_foo.py # here I create a public and a private method ---- method_bar.py # here I can import both methods with no issues, cause it is inside inferface ---- api.py # here i display the public methods for other interfaces to use them --interface_baz ----method_baz.py # here I can import ONLY public method By trying to import private methods from interface_foo inside interface_baz should raise an error (like ImportError) -

Set and not let modify foreign key value (user)
I have 2 models that I want to preset the value and ideally have it hidden from the Django admin when creating new record, this way the user don't amend this value. This are the created and modified by that are foreign keys to users.

Django Rest framework doesn't accept JWT Authentication
I'm not in that backend and python business and I'm trying to implement a JSON REST-API with django and the django restframework. For the authentication I would like to use simple jwt for django.

How to see the raw MongoDB queries Djongo is running?
I am using djongo as my backend database connector engine. The decision to use Django with MongoDB as well as the choice of using Djongo predates me tenure with the team. I am trying to improve the efficiency of a search result for which I want to know the exact "find" query that is being run on MongoDB. But I can't seem to find a way to do it. Is there a way I can see the exact query that djongo is running under the hood? Follow up: I cannot write the exact search query here but it looks something like this queryset = ( ModelName.objects.filter( Q(attr1__icontains=search_term) | Q(foreign_key1__attr__icontains=search_term) ) .distinct() .order_by("-id") ).select_related( 'foreign_key1__attr' ).values( 'attr1', 'foreign_key1__attr' ) I am a bit confused. Does Foreign Key even make sense if my backend is MongoDb? Is this shoddy DB design or does djongo implement some foreign key constraints at the middleware layer? -
Using variables in a class in django
I am trying to make a chart that displays the temperature and timestamp data, however I want to filter it. The current database this data is being taken from looks like this: And I only want the graph to display data from the specific user that is already logged in. Furthermore, I have pages for each room ID showing the data from that room and with that user, and this is where I want the graph to be displayed. So you login and go to a specific room page and the graph shows the temperature and timestamp data from that room (and of course with that username). The current structure displays the chart by uploading the JSON formatted data to a link called API, and the code to get this API data up is displayed here. class ChartData(APIView, models.Model): authentication_classes = [] permission_classes = [] def get(self, request, *args, **kwargs): labels = [] for e in Post.objects.all(): labels.append(e.timestamp) # print(e.room_id) # print(e.username) #print(e.temperature) chartLabel = "my data" chartdata = [] for e in Post.objects.all(): chartdata.append(e.temperature) data ={ "labels":labels, "chartLabel":chartLabel, "chartdata":chartdata, } return Response(data) So right now it takes every temperature and timestamp in the database and puts that on the … -

How do I enforce that child classes have all fields in the database

Django REST Framework - Struggling with nested serializer - This Field is Required
