Django Aggregation on date field
Hi I have two following models class Store(models.Model): store_name = models.CharField(max_length=100) class Meta: db_table = 'stores' class Sales(models.Model): store = models.ForeignKey(Store, on_delete=models.CASCADE, related_field='sales') product_id = models.BigInteger() sale_date = models.DateTimeField() total_mrp = models.FloatField() I am trying to fetch sum(total_mrp) of each store day wise but seem to unable to group by date col in my Sales Table I am using django_rest_framework I tried to do above using following serializers class SalesSerializer(serializers.RelatedField): queryset = Sales.objects.all() def to_representation(self, value): data = self.queryset.annotate(day=functions.ExtractWeekDay('sale_date'), total_sale=Sum('total_mrp')) return data.values('day', 'total_mrp') class StoreSerializer(serializers.ModelSerializer): primary_sales = SalesSerializer(many=False) class Meta: model = Store exclude = ['id'] The output result doesn't get grouped as I expect. Instead I get same data for primary sales for each store. -

Android app problem: UnicodeDecodeError: 'utf-8' codec can't decode byte 0xff in position 207: invalid start byte
So I have two ubuntu servers stage and dev, and one single API for android, IOS and web front on reactjs. I get this error when I try to upload a photo to my server from ANDROID app, basically I can upload the same photo to DEV server from Postman and IOS, but I keep getting this error when I try uploading from android. But from the same android app I can upload this exact photo to stage server and prod server, so basically nothing wrong with android app, but something is wrong on the server, even tho it correctly works with IOS and postman and web app. I believe that the code and settings are almost the same on both servers, so I have no idea where is the problem...

Setting permissions by group in Django
I am working with a Django project that requires user, group, and permission management to be done only through the admin panel. So I used Django's user system and created a login with this view.py # Django from django.contrib.auth import authenticate, login, logout from django.shortcuts import render, redirect from django.contrib import messages def LoginView(request): """ Login Se utiliza el modulo de usuarios de Django """ template_name = "login.html" if request.method == 'POST': username = request.POST.get('username') password = request.POST.get('password') user = authenticate(request, username=username, password=password) if user is not None: login(request, user) if request.user.groups.filter(name="administradores").exists(): return redirect('inicio') else: return redirect('listarS') else: messages.error(request, 'Error en el ingreso') else: messages.error(request, 'Error en CUIT o contraseña') context = {} return render(request, 'login.html', context) def LogoutView(request): """ Logout de Django """ template_name = "login.html" context = {} logout(request) return redirect(request, 'login.html', context) Groups are administradores and operadores. Users from operadores group only have permissions on specific model group permissions But when I add a user to this group: user group When logging in, this user can do anything (add, modify, delete or list) in any model of the application. How should I do so that the users of the operadores group only have the permissions of that … -
Adding values to cells in a specific column in HTML
I am creating a very basic table in HTML for my Django project. I got some help from Here to learn how to pass a list from my Django app to my HTML and generate rows for my values. My question this time is: how can I target the second, third, or any particular column for my list? For example, suppose I have a list of values and want to add all of them to Column 3 of my table. Here is the code I tried to use where i wanted to have {{ name }} values added to column two, but it keeps adding the cells to the first column <html> <body> <table border="1" cellpadding = "5" cellspacing="5"> <tr> <th> IDs </th> <th> Names </th> <th> Heights </th> </tr> {% for id in myIDs %} <tr> <td>{{ id }}</td> </tr> {% endfor %} <tr> {% for name in myNames %} <td> <tr> <td>{{ name }}</td> </tr> </td> {% endfor %} </tr> </table> </body> </html> -

Sum and Annotate does not returns a decimal field Sum as a decimal
I am writing a query in which I want to Sum amount using annotate and Sum decimal field in a foreign key relationship. The field is summed correctly but it returns the Sum field in integer instead of decimal. In the database the field is in decimal format. The query is like... **models.objects.filter(SourceDeletedFlat=False).annotate(TotalAmount=Sum("RequestOrderList__PurchaseOrderAmount")).all(). I do not want to use aggregate because I don't need overall column sum. -

Django Rest Framework: Delete multiple Cookies with same name but different domain?
I have an application running on different shards and each shard has a different domain. I am setting that domain as a domain for our cookies for respective environments. And the problem I am facing is that sometimes cookies from previous sessions (might be from different environments) are present in the browser. So When I try to perform certain actions then a cookie from the different session is used and validation failed. So now I want to delete those cookies with the same name. What I am doing is response.delete_cookie('profileActionId') But after this the cookies was something like this: profileActionID: 'cookie_value' :: domain: 'usa.example.com/' profileActionID: '' :: domain: 'example.com/' So this doesn't delete cookies with the same name which have a different domain and I don't have a way to access that different domain from the code and also can't hardcode it as It will change according to different environments. Also I can't change the domain for cookies for different environments. So Is there a way in Django by which we can delete all cookies with the same name irrespective of there domains or paths? -
Do I need to use a inline formset? Or am I over complicating my models?
I’m trying to create an app that stores golf round scores. This will have things like the course being played, which tees being used, etc. what’s causing me problems is this could have 1-4 players. I would like to use 1 model for this, but I don’t think it would be possible because I need one instance of the course criteria, while 1-4 instances for the players. Am I overthinking my models? Or does this sound correct.

How to Get same Connection id in django for every file
Every time I run my Django webservice the connection (django and MySQL connector) is same for every python function that I call but Connection_id from MySQL workbench is different for every python function. My temporary table keeps dropping from the DB which was created from a python function A and has to be accessed by another independent python function B at a later point of time from a different webservice. I guess the temporary table is being dropped as a result of new instances(connection_id) getting generated in the MySQL DB everytime I run a webservice to call my python functions. Example outputs of connections: Mysql Connection ID: 18423 django connection: <django.utils.connection.ConnectionProxy object at 0x00000203C0C84340> mysql connection: <mysql.connector.connection_cext.CMySQLConnection object at 0x00000203C1B7C070> Mysql Connection ID: 18424 django connection: <django.utils.connection.ConnectionProxy object at 0x00000203C0C84340> mysql connection: <mysql.connector.connection_cext.CMySQLConnection object at 0x00000203C1B7C070> Expectation Example outputs of connections: Mysql Connection ID: 18423 django connection: <django.utils.connection.ConnectionProxy object at 0x00000203C0C84340> mysql connection: <mysql.connector.connection_cext.CMySQLConnection object at 0x00000203C1B7C070> same nexttime Mysql Connection ID: 18423 django connection: <django.utils.connection.ConnectionProxy object at 0x00000203C0C84340> mysql connection: <mysql.connector.connection_cext.CMySQLConnection object at 0x00000203C1B7C070> -

auth_user table created alongside accounts_user table in postgres(Django)
Using: class User(AbstractBaseUser): pass #models here I added extra fields to my custom user model. This table is created successfully in postgres with absolutely no issues, however, whilst creating a superuser the credentials gets pushed to auth_user(default django user table) instead of account_user. auth_user shouldn't even be created alongside accounts_user?! Even worse: REQUIRED_FIELDS = ['username', 'first_name', 'last_name'] which I set isn't required at all when creating superuser. It still uses default django configurations/fields. These are in order if you're wondering: AUTH_USER_MODELS = 'accounts.User' and installed 'accounts' in INSTALLED_APPS=[ ]. What is happening? Superuser credentials should be created in accounts_user table not auth_table in postgreSQL. REQUIRED_FIELDS = ['username', 'first_name', 'last_name'] should be requested whilst creating superuser. -
