What side effects will come from overriding a custom model manager's create() method?
I am implementing custom model managers, and it looks like the rest_framework by default calls the create() method of a model manager from within its serializer to create a new object. To avoid creating custom views when using a custom model manager, it seems like I could just override the create() method of my custom model manager, and implement standard ViewSets without any customization, but I don't fully understand what side-effects, if any, this will cause. Do I have to call super().create() within the overridden function to get other pieces of django to behave properly? I cannot find anywhere in the django documentation about overriding a custom model manager's create() method, which leads me to think they did not consider it as a use case, and there may be unintended consequences. Is this the case? Why does the standard recommendation seem to be to create a new create_xxx method inside the custom model manager? (i.e. creating a custom user model manager) -
Django manage.py migrate errors
I've been working on a project for CS50-Web for a while now and I was changing some of my models trying to add a unique attribute to some things. Long story short it wasn't working how I wanted so I went back to how I had it previously and now something is wrong and I can get it to migrate the changes to the model. I don't understand what to do because it was working fine before. Please can someone help I so frustrated and annoyed that I've broken it after so many hours of work.

Django - How to compare different models with same foreign key
I'm really stuck in how to do this and appreciate the help. I have three models, two of them shares the same foreign key field: class AccountsPlan (models.Model): code = models.CharField(max_length=7, unique=True,) name = models.CharField(max_length=100, unique=True,) class Planning (models.Model): accountplan = models.ForeignKey(AccountsPlan, on_delete=models.PROTECT) month = models.DateField() amount = models.DecimalField(max_digits=14, decimal_places=2,) class Revenue (models.Model): accountplan = models.ForeignKey(AccountsPlan, on_delete=models.PROTECT) receipt_date = models.DateField() amount = models.DecimalField(max_digits=14, decimal_places=2,) And I have this view that annotates the sum for each model by the foreign key name with a form that filters by date: def proj_planning(request): form = ProjectionFilterForm(request.POST or None) # some definitions for the form planned = Planning.objects.values('accountplan__name').annotate(Sum('amount')).order_by('accountplan__code').filter( month__range=[start_date, planned_end_date]) done = Revenue.objects.values('accountplan__name').annotate(Sum('amount')).filter( receipt_date__range=[start_date, end_date],).order_by('accountplan__code') if request.method == 'POST': planned = Planning.objects.values('accountplan__name').annotate(Sum('amount')).order_by( 'accountplan__code').filter(month__range=[start_date, planned_end_date], accountplan__name__icontains=form['accountplan'].value()) done = Revenue.objects.values('accountplan__name').annotate( Sum('amount')).filter(receipt_date__range=[start_date, end_date], accountplan__name__icontains=form['accountplan'].value()) comp_zippedlist = zip(planned, done) return render(request, 'confi/pages/planning/proj_planning.html', context={ 'form': form, 'list': comp_zippedlist, }) The code kinda works (it doesn't throw any errors), but the thing is, I will never have an exact amount of data for each model.

Axios POST method with React shows as Anonymous user and CORS error in Django Backend
I have been succesfully using GET methods with Axios while the logged in user information is succesfully transmitted to backend with the following code : await axios({ method: 'get', url: BASE_BACKEND_URL + `/project/` + project_uuid + `/`, data: {}, headers: { 'Content-Type': 'application/octet-stream' }, withCredentials: true, }) class ProjectView(APIView): def get(self, request, uuid): logging.info("ProjectManifest GET begin") user = request.user print(user) When I use a similar code with the POST API call of the same function, Django backend shows the request has been requested by an anonymous user instead of the logged in user. The code for the POST command is below: await axios({ method: 'post', url: BASE_BACKEND_URL + '/project/' + project_uuid + '/', data: { project_uuid : projectJSON }, headers: { 'Content-Type': 'application/json', }, withCredentials: true, }) class ProjectView(APIView): def post(self, request, uuid): logging.info(f"ProjectManifest POST begin: {request.user}") How can I make the react axios post call to work properly with Django backend ? -

Problems filtering columns that have many rows with a None value(Django database)
I am filtering a certain column in PostgreSQL database. n = Database.objects.values(column).count() for i in range(0, n): name = list(Database.objects.all().values_list(column, flat=True))[i] There are 105 lines. From line 86 onwards the values are None. However, when querying line 43, the returned value is None, although in the database this line is filled with a value. Strangely, when I populate lines 86 onwards, the query on line 43 is correct and does not return a None value. I want to know if there is any problem when filtering columns that have many None values and why this might be happening -

Python Django - Passing in multiple parameters to Factory during testing
I'm currently working on a practice social media app. In this app, current users can invite their friends by email to join the app (specifically, joining a 'channel' of the app, like Discord). For this project, I'm working on functionality where a user will get an error if they try to invite someone who is already in the app (meaning people who are already in the app's database). I'm working on unit tests that ensures the error messages pop up when users are detected as already existing. I managed to get my first scenario working, but I'm a bit stumped for the second one.

What does django's Manager.create() method do?
I was poking around in the rest_framework trying to figure out how it works, and came across a call to Model.objects.create(), but I can't for the life of me find the create() method for django model managers in the docs or the source code. It looks to be dynamically generated. What does it do, exactly? Where can I find its code? If I wanted to override it, what would my implementation have to do? I found this question but it only says to call the super().create() method. -

They are also named correctly as HTML files: my html files I tried to create 2 pages using the exact same way I created my others using the class-based views. I get an error this time when clicking on the buttons to take me to the 2 pages. -
django.core.exceptions.AppRegistryNotReady: Apps aren't loaded yet | APScheduler
I have this APScheduler code: import atexit from apscheduler.schedulers.background import BackgroundScheduler from main.utils import run_employee_import scheduler = BackgroundScheduler() scheduler.add_job(run_employee_import, "interval", minutes=2) scheduler.start() # Shut down the scheduler when exiting the app atexit.register(lambda: scheduler.shutdown()) When I add this code to settings.py to run it when the app starts to run, it gives me the following error: raise AppRegistryNotReady("Apps aren't loaded yet.") django.core.exceptions.AppRegistryNotReady: Apps aren't loaded yet. PS: I did not include the run_employee_import code because I tested it already (replaced its content with a simple pass) and nothing changed, so it is irrelevant to the error. -
How to use a Django (Python) Login Form?
I builded a login form in Django. Now I have a problem with the routing. When I select the login button, the form doesn`t send the correct awnser. I think the form in the frontend cannot gets the correct awnser from the view.py file. So it will send no awnser and the login process canot work and the form is a simple static html form. I hope you can help me. HTML: <form class="windowlogscreen-content" method="POST" action={% url 'homepage' %}\> {% csrf_token %} <input type="text" placeholder="account" name="username"> <br> <input type="password" placeholder="password" name="password"> <br> <button style="margin: 20px;" type="submit">join</button> </div> </div> </form> views.py def loginuser(request): if request.method == "POST": username = request.POST\['accountName'\] password = request.POST\['accountPassword'\] user = authenticate(request, username=username, password=password) if user is not None: login(request, user) return views.homepage else: return redirect('start') else: return render(request, 'start', {})
