Django model object query misbehaving
I am trying to display the contents of a profile which is a model that is linked to the inbuilt User model. Everything works fine, strangely except the last object entry of the model. For example if user8 is the last model object logging in with user1 to user 7 is working with all the contents inside verified belonging to the current user. but when I login using the last object ie. user8 in this case I get a Page 404 not found : No (Model name) matches the given query error. to be bit more clear, now if I create another user called user9 , Now I am able to login with user8 but not with the lastly created user9. **views.py : ** # Create your views here. def home(request): if request.user.is_authenticated: contextvar = Post.objects.all() user_content = get_object_or_404(user_profile, pk = request.user.pk) # user_content = user_profile.objects.get(pk=request.user.pk) # user_content = user_profile.objects.get(pk='8') print("the current users id is " , request.user.pk) return render(request,'homepage.htm', {'context':contextvar , 'user_content' : user_content , "up" : request.user.pk }) else: contextvar = Post.objects.all() return render(request,'homepage.htm', {'context':contextvar}) models.py : from django.db import models from django.contrib.auth.models import User # Create your models here. class user_profile(models.Model): #using default User model by linking … -

How to use Async views and urls in Django?
I build an application using django that can get data from an api. At first, I used the python requests to connect to the api and it's working. But the problem is I find it a little bit slow when it comes to the web page loading speed. So i decided to use async function in my codes, but i keep getting an error . Here's my codes: views.py async def e_sign_page(request): start_time = time.time() template_name = "e_sign/e_sign_table.html" url = f"API_URL_HERE" async with aiohttp.ClientSession() as session: esign = [] doc = asyncio.ensure_future(fetch(session, url)) esign.append(doc) docs = await asyncio.gather(*esign) end_time = time.time() total = end_time - start_time print("Code Execution Time : ", total) context = { 'docs' : docs } return render(request, template_name, context) urls.py from django.urls import path from e_sign.resources.e_sign import ( e_sign_page, ) urlpatterns = [ path("e-sign-page/", e_sign_page, name = "e_sign_page"), ] utils.py async def fetch(session, url): async with session.get(url) as resp: assert resp.status == 200 return await resp.json() Here's my errors that I'm receiving 'coroutine' object has no attribute 'get' How to fix this? -
Get the value of the token from authentication in Django
I have made a customized token Authentication for my app. It is based on a specific model that stores the tokens that I will be generating. class ApiKeyAuthentication(TokenAuthentication): keyword = "api-key" def get_token_from_auth_header(self, auth): auth = auth.split() #validations here def authenticate(self, request): auth = get_authorization_header(request) token = self.get_token_from_auth_header(auth) if token: return self.authenticate_credentials(token) def authenticate_credentials(self, key): try: token = TokenModel.objects.get(key=key) except TokenModel.DoesNotExist: raise exceptions.AuthenticationFailed("Invalid Api key.") user = User.objects.first() return (user, token) Is there a possibility to get the values of the token that was returned upon authenticate_credentials? I have to access a field from that model ( TokenModel ) on the views.py. -
Cannot group by an aliased field in Django
I have two django models (db tables): class Assignment(models.Model): title = models.CharField(max_length=255) # Some fields ... class Task(models.Model): assignment = models.ForeignKey(to=Assignment, on_delete=models.CASCADE, related_name='tasks') deadline = models.DateField() There can be many tasks related to a single assignment. The deadline of an assignment is the latest deadline from its children tasks. Let's assume I want to group assignments by deadlines statuses and , e.g. If the deadline of the assignment is in 5 days, then status is 'DUE_SOON', If the deadline has passed, then status is 'EXPIRED' Otherwise, status is 'OK' Here is what I came up with: I am annotating new field called date_diff which is difference between the maximum of the children's deadline today's date (e.g. if deadline is 2021-02-25 and today is 2021-02-19, then date_diff is 6) Then I am annotating a field deadline_status, which is calculated based on date_diff (e.g. if date_diff < 0, then 'EXPIRED', etc.) And finally, I group the queryset by the deadline_status Assignment.objects.annotate( date_diff=ExpressionWrapper( Max(F('tasks__deadline')) - date.today(), output_field=IntegerField() ), deadline_status=Case( When(date_diff__lt=0, then=Value('EXPIRED')), When(date_diff__lte=5, then=Value('DUE_SOON')), default=Value('OK'), output_field=CharField() ) ).order_by().values('deadline_status').annotate( count=Count('deadline_status') ) But, when I run the code above it raises an error: Cannot compute Count('deadline_status'): 'deadline_status' is an aggregate What is the problem? -
Django - How to make multiple self join tables?
I have a table like this: Its model: class RLocation(models.Model): id = models.CharField(primary_key=True) Parent_ID = models.CharField(unique=True, max_length=255, blank=True, null=True) Name = models.CharField(max_length=255, blank=True, null=True) Geo = models.TextField(blank=True, null=True) Sample data: ID Parent_ID Name Geo 1 Null City A ABC1 City A 12 1 District 1 ABC002 District 1 in City A 123 12 Ward 1 ABC002003 Ward 1 in District 1 in City A 25 1 District 5 XYZ004 District 5 in City A 251 25 Ward 4 XYZ002006 Ward 4 in District 5 in City A Normally, I got the ID of the ward (third in the hierarchical). I need to to do query to get the GEO of the city (first in the herarchical). In query (PostgreSQL), I would do something like this : SELECT l1.Geo FROM routing.r_location l1 LEFT JOIN routing.r_location l2 ON l1.ID= l2.Parent_ID LEFT JOIN routing.r_location l3 ON l2.ID= l3.Parent_ID WHERE l3.ID= '123' Here is my so far code, but I dont really like it: Parent_ID_lv3 = RLocation.objects.filter(ID = 123).values('Parent_ID') Parent_ID_lv2 = RLocation.objects.filter(ID = Parent_ID_lv3).values('Parent_ID') Geo_lv1 = RLocation.objects.filter(ID = Parent_ID_lv2).values('Geo') -
Django model filter with default value
I wanna do something similar as here, but I want a filter with default value if it's not passed as parameter. E.G: class MyUserManager(models.Manager): def get_queryset(self, is_active=True): return super().get_queryset().filter(is_active=is_active) class User(AbstractUser): # ... manager = MyUserManager() So I don't have to remember to filter with is_active=True every time since I will want only active users all the time, except when I intentionally pass is_active=False. I don't think get_queryset() override works for this case. -

Django: How to dynamically store user data in sessions?
I am trying to create different django-allauth signup forms for different types of users. So different forms for different user types. Once a user selects a user type (example: "I want to sign up as a vendor"), they should be redirected to a different form where they will fill up other signup and profile details before email confirmation and login. I have one signup form working, but not multiple. Currently I have a general purpose form assigned to users/accounts/signup/ but I also want a vendor specific signup form assigned to users/accounts/signup_vendor/. The best possible solution I've found is provided by the django-allauth author, stating: "There are multiple ways to approach this. You could store the desired user type into the session, and dynamically construct your form fields depending on that.

Why Django Validates Multiple Forms
I have a settings template which includes different forms. When I submit a form and it is not valid, other forms are asigned as invalid and shows validation errors. What I want is showing error just for the form which is submitted. Is there a solution for this problem? Here is my code. I can share html and form codes if needed. user = request.user if request.method == "POST": edit_profile_info_form=EditProfileInfo(request.POST or None) edit_account_form=EditAccountForm(request.POST or None) context = { "profile_info_form" : edit_profile_info_form, "account_form" : edit_account_form, } if "profile_info_submit" in request.POST: if edit_profile_info_form.is_valid(): first_name=edit_profile_info_form.cleaned_data.get("first_name") last_name=edit_profile_info_form.cleaned_data.get("last_name") user.first_name=first_name user.last_name=last_name user.save() messages.success(request,"Changes saved") return redirect("user:settings") return render(request,"settings.html",context=context) if "account_submit" in request.POST: if edit_account_form.is_valid(): username = edit_account_form.cleaned_data.get("username") user.username = username user.save() messages.success(request,"Changes saved") return redirect("user:settings") return render(request,"settings.html",context=context) else: edit_profile_info_form=EditProfileInfo(initial{"first_name":user.first_name, "last_name":user.last_name}) edit_account_form=EditAccountForm(initial={"username":user}) context = { "profile_info_form" : edit_profile_info_form, "account_form" : edit_account_form, "password_form" : edit_password_form, "delete_form" : delete_account_form, } return render(request,"settings.html",context=context) -

I'd like to have a multi-selection widget. In order to do this, I tried all of the mentioned solutions in here and here but none of them works. I receive the following error.

Django REST Framework PDF Generation
I am currently developing the back-end for a mobile application using Django REST Framework. The app has a feature where the user can request a pdf report. I am not sure whether to use ReportLab to generate the report or to create an html template and then convert that to a pdf.
