Cannot install mysqlclient for my Django project using pip on ZorinOS

Does anyone know if i can add an image upload function to a form with cloudinary?
I'm building a Django blog in which i want registered users to be able to create their own blog posts including a title image. i've incorporated cloudinary but can currently only upload images through the admin panel.

Django serializer returns empty dictionary on create
I have this model that basically joins two different users: class Couple(models.Model): id = models.UUIDField( primary_key=True, default=uuid.uuid4, editable=False) user1 = models.ForeignKey( settings.AUTH_USER_MODEL, on_delete=models.CASCADE, null=True, blank=False, related_name="user1" ) user2 = models.ForeignKey( settings.AUTH_USER_MODEL, on_delete=models.CASCADE, null=True, blank=False, related_name="user2" ) def __str__(self): return str(self.id) What I did next, was create a Serializer where user1 invites user2 to create a couple. And I want to do this by writing user2 email address: class CreateCoupleSerializer(serializers.Serializer): partner_email = serializers.EmailField(write_only=True, max_length=250, required=True) def create(self, validated_data): partner_email = validated_data['partner_email'] try: partner = User.objects.get(email=partner_email) except Exception: partner = None if not partner: raise serializers.ValidationError( {"details": 'User does not exist'}) if partner.couple_id: raise serializers.ValidationError( {"details": 'User is already assigned to a couple'}) user = self.context['request'].user couple = Couple.objects.create(user1=user, user2=partner) user.couple_id = couple.id partner.couple_id = couple.id user.save() partner.save() return couple And this is my view: class CreateCoupleView(generics.CreateAPIView): serializer_class = CreateCoupleSerializer queryset = Couple.objects.all() By testing this I can see that the Couple is being created, which is great! However, in my body response, I'm getting an empty dictionary instead of the new couple instance. My question is why is this happening? Bonus question: When should I create logic in def create() from the Serializer side vs def create() on the View side? … -
Annotate on reverse many-to-many
I'm trying to work out why this doesn't work:- class A(models.Model): contacts = models.ManyToManyField(Contact) class Contact(models.Model): name = models.CharField() If I try and get a count of how many A there are with multiple contacts:- A.objects.annotate(num_contacts=Count('contacts')).filter(num_contacts__gt=1).count() there are 10. but if I have a particular contact and I want to get a count of how many A's they are connected to that have more than 1 contact on them:- B.a_set.annotate(num_contacts=Count('contacts')).filter(num_contacts__gt=1).count() I get 0. The num_contacts count always comes out as 1, even when the A has more than 1 contact. I must have missed something silly but I can't see it. Any ideas? -
django select_for_update(nowait=False) in transaction.atomic() does not work as expected
I have a django app that needs to get a unique ID. Many threads run at the same time that need one. I would like the IDs to be sequential. When I need a unique ID I do this: with transaction.atomic(): max_batch_id = JobStatus.objects.select_for_update(nowait=False).aggregate(Max('batch_id')) json_dict['batch_id'] = max_batch_id['batch_id__max'] + 1 status_row = JobStatus(**json_dict) status_row.save() But multiple jobs are getting the same ID. Why does the code not work as I expect? What is a better way to accomplish what I need? I cannot use the row id as there are many rows that have the same batch_id. -
"No such table" error coming from serializers.py file, when running migration command
I recently moved my Django app from using the default User model to a custom User model, and since this is not recommended to do mid-way through a project, I had to drop the database and migrations and recreate migrations and run migrate. This works fine when I comment out the entire serializers.py file, as well as comment out everywhere it is referred to. However, now that I want to be able to action all the new migration steps at production level WITHOUT having to comment out serializers.py. I know that I have referenced a table that doesn't technically exist so, I'm just wondering what is the best way to do this? Here is my serializers.py code: class MyModelSerializer(serializers.Serializer): features = Feature.objects.values_list("feature_name", flat=True) # Feature is a model feature = serializers.ChoiceField(features) # this is where the error happens The error says: "no such table: myapp_feature" -
Best way to store multiple date in one object django

Django DateTimeField Timestamp value has an invalid format. It must be in YYYY-MM-DD HH:MM[:ss[.uuuuuu]][TZ] format
The environment is: Django 4.0 (venv) Python 3.8 Postgres 15 Elementary OS 6.1 The initial model: class MyModel(models.Model): created = models.DateTimeField(auto_now_add=True) updated = models.DateTimeField(auto_now=True) Upon saving a new record (without providing any value for "created" nor "updated") the result was: django.core.exceptions.ValidationError: ['“1669827388000” value has an invalid format.

How to assign multiple api views to single endpoint in django rest framework?
I have a model named Article and a few api views for it. They are divided for diffrent purposes (for example ArticleUpdateAPI class for UPDATE http method, ArticleDeleteAPI for DELETE method etc). In urls.py they are separated to diffrent endpoints (aritcle/pk/update, /article/pk/delete etc). As I know, it's not good practice to build endpoint like this, so I want to bind them to single url and use diffrent classes for handling diffrent http methods. Is it possible and how? Examples are below ArticleAPI.py class ArticlePostAPI(generics.CreateAPIView): serializer_class = ArticleSerializer permission_classes = [ permissions.IsAuthenticatedOrReadOnly ] def post(self, request, *args, **kwargs): serializer = self.get_serializer(data=request.data) serializer.is_valid(raise_exception=True) serializer.save() return Response({ "comment": CommentSerializer.data }, status=201) class ArticleRetrieveAPI(generics.RetrieveAPIView): serializer_class = ArticleSerializer queryset = Article.objects.all() permission_classes = [ permissions.AllowAny ] class ArticleListAPI(generics.ListAPIView): serializer_class = ArticleSerializer queryset = Article.objects.order_by('number', 'headline') permission_classes = [ permissions.AllowAny ] class ArticleUpdateAPI(generics.UpdateAPIView): serializer_class = ArticleSerializer queryset = Article.objects.all() permission_classes = [ permissions.IsAuthenticated ] lookup_field = 'pk' def update(self, request, *args, **kwargs): instance = self.get_object() if request.user != instance.author: return Response({ "errors": "Logged in user and author must be same" }, status=403) serializer = self.get_serializer(instance, data=request.data, partial=True) serializer.is_valid(raise_exception=True) self.perform_update(serializer) return Response(serializer.data) urls.py urlpatterns = [ ... # Article API path('article/post/', ArticlePostAPI.as_view(), name='article_creation'), path('article/<int:pk>/', ArticleRetrieveAPI.as_view(), name='article_retrieve'), path('article/', … -
Django Rest Framwork : Nested objects in one serializers
I have double nested serializer situation... i have three models : Reports, ReportPages and widgets , upon trying to create a specific endpoind that is : payload { "since_date": "some date", "until_date": "some other date that is greater than since_date", "report_pages": [ { "page_number": "some number" (generated from front end, of type integer) "widgets": [ { "data": ["some array"], "width": "some number", "height": "some number", "top_position": "some number", "left_position": "some number", "widget_type": "" (either "Label", "LineChart", "Bar" or "PieChart"), } ] } ] } I faced a problem with nested serializer, i was only able to create the first half which is : payload { "since_date": "some date", "until_date": "some other date that is greater than since_date", "report_pages": [ { "page_number": "some number" (generated from front end, of type integer) ] } Knowing that the creation of a report is separate from this endpoint, so i override the update method and structure looks like this : Report{ report_page{ widgets {} } } My models : class Reports(models.Model): id = models.AutoField(primary_key=True) name = models.CharField(max_length=500, null=True) since_date = models.DateTimeField(null=True) until_date = models.DateTimeField(null=True) def __str__(self): return self.name class ReportPages(models.Model): id = models.AutoField(primary_key=True) number = models.IntegerField(null=True) report = models.ForeignKey(Reports, related_name="report_pages",on_delete=models.CASCADE) def __str__(self): return self.number … -

Django CountryField, query by country
I have a class similar to this: class Person(models.Model): name = CharField(max_length=255) citizenship = CountryField(multiple=True) In this example a Person can have more than one citizenship.

Is there a django-countries way to do this? I suppose I could treat it like a CharField. If I wanted to do something more complex like "is Person a citizen of US or GB", I was hoping there was a nicer way than a complex CharField query. -
Django user is_authenticated vs. is_active
After reading the documentation, I still don't fully grasp the difference between these two User methods: is_authenticated and is_active. Both are returning a boolean. While is_authenticated is read-only (and you get an error if you try to set it), is_active can be modified and for instance you can set it to False instead of deleting account. Running these commands, will de-activate a user: >>> from django.contrib.auth.models import User >>> u = User.objects.get(pk=10) # get an arbitrary user >>> u.is_active True >>> u.is_active = False # change the value >>> u.save() # save to make effective >>> u.is_authenticated True Now, this user is still authenticated but is not able to login anymore. The login view uses authenticate(). What is actually happening that the login for a de-activated user fails? if request.method == 'POST': username = request.POST['username'] password = request.POST['password1'] user = authenticate(request, username=username, password=password) if user is not None: login(request, user) To verify the credentials you use authenticate() which returns a User object in case of success or None otherwise. I guess it returns None in case the supplied credentials are correct but is_active is False. In addition, the Jinja block {% if user.is_authenticated %} evaluates as false if is_active is … -

Half of the dropdown is hidden
I made a django app with a navbar. On the right corner, it has a user area with some things, like profile and logout area.
