Migrating from SQLite to MySQL Django (not working)
I'm trying to implement the MySQL instead of the SQLite, and the instructions are pretty straight forward, but, when I run the server again it stops after the system check identified no issues (0 silenced)., which indicates that it can't establish a connection to the database. but everything checks out. I did this step in the database migration: Installing Mysql server && mysqlclient Create a database and a user and grant all permissions to that database add to the setting.py file the database & user settings: DATABASES = { 'default': { 'ENGINE': 'django.db.backends.mysql', 'NAME': 'auth', 'USER': 'admin', 'PASSWORD': 'password', 'HOST': '127.0.0.1', """localhost not working (Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2))""" 'PORT': '3306', } } Am I missing anything out?

Django not creating a table in the Development Server
I've been trying to fix this problem, but couldn't find a solution, tried a bunch of fixes online. The problem I'm facing. I have a Django project running on Hawuei Cloud, I've made some changes and wanted to test it on the Development server before going to production. The project is running fine, BUT, there's a table that is not being created for some reason, so the parts of the project that uses that table, throws an error. But the thing is the changes I've made weren't on that table. I don't understand why that table isn't being created, I never had this issue. This is a small part of the model class Regime(models.Model): inventario = models.ForeignKey(Inventario, on_delete=models.CASCADE) nome = models.CharField(max_length=50) def __str__(self): return self.nome class Unidade(models.Model): empresa = models.ForeignKey(Empresa, on_delete=models.CASCADE) codigo = models.CharField(max_length=50) descricao = models.CharField(max_length=100) cnpj = models.CharField(max_length=20) def __str__(self): return self.descricao class Conta(models.Model): empresa = models.ForeignKey(Empresa, on_delete=models.CASCADE) codigo = models.CharField(max_length=50) descricao = models.CharField(max_length=100) def __str__(self): return self.descricao class Local(models.Model): empresa = models.ForeignKey(Empresa, on_delete=models.CASCADE) codigo = models.CharField(max_length=50) descricao = models.CharField(max_length=100) def __str__(self): return self.descricao The table Unidade is not being created, the other similar ones like Local and Conta work just fine.

How to change the attributes of Django login form
My site is RTL so I need to adjust the direction of some fields to LTR (username, email, password, etc). One of them is the Password Change form so this is what I do: forms.py from django.contrib.auth.forms import PasswordChangeForm class CustomPasswordChangeForm(PasswordChangeForm): def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) self.fields['old_password'].widget.attrs.update({'dir': 'ltr'}) self.fields['new_password1'].widget.attrs.update({'dir': 'ltr'}) self.fields['new_password2'].widget.attrs.update({'dir': 'ltr'}) After creating the required view and URL path, that works perfectly and all 3 fields are LTR. The other one is the Login Form so I do the same thing: forms.py from django.contrib.auth.forms import AuthenticationForm class CustomAuthenticationForm(AuthenticationForm): def __init__(self, request=None, *args, **kwargs): super().__init__(request, *args, **kwargs) self.fields['username'].widget.attrs.update({'dir': 'ltr'}) self.fields['password'].widget.attrs.update({'dir': 'ltr'}) This time, the above code does not have any effect. Both fields are still RTL. So why it works for password change and not for login and what's the solution for login form? -

Issue concercing cookie setting in django on browser, works fine on postman
I am experiencing an issue, I am using django 5 for my backend and nuxt 3 for my frontend. I have this view in django: @action(detail=False, methods=['POST']) def login(self,request): username = request.data['username'] password = request.data['password'] user = authenticate(request,username=username, password=password) if user is not None: login(request,user) sessionid = request.session.session_key return Response({'message': "Logged in!", 'sessionid': sessionid}) else: return Response({'message': "Invalid credentials provided",'username': username, 'password': password}, status=status.HTTP_400_BAD_REQUEST) And when I do a post request with the proper credentials on postman, I get a 200 OK response, with the cookies being set. On the frontend I also get a 200 OK response and the set_cookie response headers for both the sessionid and csrftoken are there. However in all subsequent requests, the request cookies tab is empty and there is no 'cookie' header. I had solved this issue, at least I thought and was able to get the sessionid cookie to be set after changing some of it's settings. However the csrftoken was still not being set despite me giving it the same settings. During the process of trying to get the csrftoken to work, the sessionid stopped being set. I tried reverting it's settings back to how it were, that didn't work so I … -
Count the number of users following a ticker in django
I need to get the top stock tickers followed by users, the issue is when two users or more follow the same ticker, it get repeated when using the query Tickers.objects.annotate(followers=Count('users')).order_by('followers') as shown here: In this example, the ticker FDCFF needs to be the top ticker since two users are following it, instead it gets repeated and its not being shown as the top followed ticker.

How properly configure Entity Attribute Value pattern in django?
I have a product model: class Product(models.Model): title = models.CharField(max_length=255) description = models.TextField(null=True, blank=True) category = models.ForeignKey('Category', on_delete=models.CASCADE) price = models.FloatField() discount = models.IntegerField() # stands for percentage count = models.IntegerField() priority = models.IntegerField(default=0) brand = models.ForeignKey('Brand', on_delete=models.SET_NULL, null=True, blank=True) tags = models.ManyToManyField(Tag, blank=True) def __str__(self): return self.title Now I want to implement entity attribute value pattern as different products can have different specifications. I understood the traditional way of EAV. But I read in wikipedia as postgresql has jsonb column type and this allows performance improvements by factors of a thousand or more over traditional EAV table designs. My database in postgresql. So what is the best practice to implement EAV (or dynamic set relationship with attributes)? Should I just add like: class ProductVariant(models.Model): product = models.ForeignKey(Product, on_delete=models.CASCADE) specifications = models.JSONField() And also I want to handle price and count (in stock) differently for each variant, let's say there are 10 shoes with size 10 and color red which price is 100 dollars and 2 shoes with size 9 and color blue which price is 120 dollars. -

This might be because I am on SQLite. using Q and regex: queryset.filter(Q(data__regex=r'"name":.*"test"')) but this always leads to empty querysets.
