How to restrict view in Django from other users?
I am trying to make a page that only can be seen by the user for who the results belongs to. So I like to make that only the user with user_name_id=1 (and the superuser) could see the page that is localhost:8000/mpa/sum/1/ I tried in the html this: {% if request.user.is_superuser %} <div class="container text-justify p-5"> <div class="display-4 text-left text-primary my-3"> ... {% else %} You are not able to view this page! {% endif %} This works fine with the superuser but how could I do this with the users? views.py @login_required def individual_sum(request, user_name_id): ... lots of query context = { ... lots of contexts } return render(request, 'stressz/individual_sum.html', context) models.py class IndividualSum_text(models.Model): def __str__(self): return str(self.user_name) user_name = models.ForeignKey(User, on_delete=models.CASCADE, default=1) ...integerfields and textfields here -

Django CreateView not creating a new user from 3 related models through ModelForm
I've created models in a Django project, one of which is an extended User model. Initially, I was creating a user through 2 forms, UserCreationForm and EmployeeForm based of a ModelForm, then using a function based view to validate the data and save it. It all worked fine until I tried to introduce the third form and wanted to use the CreateView. Here are the models: class Employee(models.Model): SENIOR = 'Sr' JUNIOR = 'Jr' FIRST = 'I' SECOND = 'II' THIRD = 'III' GENERATIONAL_SUFFIX = [ (SENIOR, 'Senior'), (JUNIOR, 'Junior'), (FIRST, 'First'), (SECOND, 'Second'), (THIRD, 'Third'), ] MALE = 'male' FEMALE = 'female' OTHER = 'other' SEX = [ (MALE, 'Male'), (FEMALE, 'Female'), (OTHER, 'Other'), ] user = models.OneToOneField(User, on_delete=models.CASCADE) phone_regex = RegexValidator(regex=r'^\d{11}$', message="Phone number must be entered in the format: '09151234567'.") phone_number = models.CharField(validators=[phone_regex], max_length=11, blank=True) middle_name = models.CharField(max_length=20, blank=True) sex = models.CharField(max_length=6, choices=SEX, blank=True) suffix = models.CharField(max_length=3, choices=GENERATIONAL_SUFFIX, blank=True) birthday = models.DateField(null=True, blank=True) hire_date = models.DateField(null=True, blank=True) image = models.ImageField(blank=True, default='blank_profile_picture.jpg') slug = models.SlugField(max_length=60, blank=True, null=True) updated = models.DateTimeField(auto_now=True) @property def get_full_name(self): first_name = self.user.first_name middle_name = self.middle_name last_name = self.user.last_name if middle_name is None: full_name = f'{first_name}{" "}{last_name}' return full_name else: full_name = f'{first_name}{" "}{middle_name}{" "}{last_name}' return … -
Django annotate sum on fk_set
I'm trying to annotate sum of fields in related set: My models: class Report(models.Model): class ReportCommissionPosition(models.Model): report = models.ForeignKey(Report) reservation = models.OneToOneField("reservations.Reservation") class Reservation(models.Model): class Payment(models.Model): amount = models.DecimalField(max_digits=10, decimal_places=2) reservation = models.ForeignKey('reservations.Reservation') PAYMENT_TYPES=( ('TRANS', 'TRANS'), ('SELL', 'SELL'), payment_accounting_type = models.CharField(max_length=50, choices=PAYMENT_TYPES) I need to annotate each position of report.reportcommissionposition_set with two fields: trans_amount - Sum of all the payments with payment accounting type == 'SELL' (through reservation => payment) sum_amount - Sum of all the payments with payment accounting type == 'TRANSFER' (through reservation => payment) I have tried: for position in commission_position: position.sell_pay = position.reservation.payment_set.filter(payment_accounting_type='SELL').aggregate(amount=Sum('amount'))['amount'] But this creates new query for every element. Any thoughts? -

how to change http to https in django
If you continue to load with http from a site that can be accessed with https, the process is still alive, but you cannot enter the screen. For this I also clear the cache and turn off the pc, but the same thing happens. I ran Django with python manage.py runsslserver --certificate django.crt --key django.key. For this I set secure_ssl_redirect to true in settings.py to change http to https, but to no avail. Also, when I created a new Django project and ran it on the same server, this problem did not occur. Please help me. I've been wandering around for 2 weeks. -

Django sum values of from a for loop in template
I want to show the sum for the values (cals, protein, carbs, etc) of multiple foods in a new table but have no idea how to do it in a django template. Heres what the for loop displays {% for food in meal.foods.all %} <div class='table-container'> <table class='food-table'> <thead> <tr> <th>Name</th> <th>Calories</th> <th>Protein</th> <th>Carbs</th> <th>Fat</th> <th>Sugar</th> <th>Sodium</th> </tr> </thead> <tbody> <tr> <td>{{ food.name }}</td> <td>{{ food.calories }}</td> <td>{{ food.protein }}g</td> <td>{{ food.carbs }}g</td> <td>{{ food.fat }}g</td> <td>{{ food.sugar }}g</td> <td>{{ food.sodium }}mg</td> </tr> </tbody> </table> </div> {% endfor %} The new table would look like this but just display the totals. -

Save a field as hash and compare it in django
I created my own user model: class CustomUser(AbstractBaseUser,PermissionsMixin): phone_number = models.CharField(verbose_name="Mobile Number", max_length=11, unique=True, blank=False, null=False) security_code = models.IntegerField(verbose_name="Security Code",default=create_security_code) security_code_creation = models.DateTimeField(auto_now=True) a user can login with password or security code. I will text them the security code if needed. but I don't want to store security code as plain text in my database. I want to store it like password (hashed). I found from django.contrib.auth.hashers import make_password which I can use to create a hashed version of security code. my question is should I write a separate authentication backend or simply write/use a function like check_password that is implanted in AbstractBaseUser? -
Validating nested dictionaries containing dynamic keys using DRF Serializers
I am working on writing serializers for an existing API for the purpose of auto-generating OpenAPI documentation for the project. One of the issues I'm running into is defining serializers to validate the returned data from some of the views. Here is the structure of the data: { "airmass_data": { "site-A": { "times": ["2021-09-09T09:54","2021-09-09T10:04"], "airmasses": [2.900041850251779, 2.687634707193725] }, "site-B": { "times": ["2021-09-09T09:54","2021-09-09T10:04"], "airmasses": [2.900041850251779, 2.687634707193725] }, ... }, "airmass_limit": 3.19 } There can be an arbitrary number of "site-X" keys, and they are dynamically generated - which is definitely part of my issue. Here is how I've set up my serializers, which I think mostly matches my dictionary structure: class SiteAirmassDatumSerializer(serializers.Serializer): times = serializers.ListField(child=serializers.CharField()) airmasses = serializers.ListField(child=serializers.FloatField()) class SiteAirmassSerializer(serializers.Serializer): site = SiteAirmassDatumSerializer(source='*') class AirmassSerializer(serializers.Serializer): airmass_data = SiteAirmassSerializer(source='*') airmass_limit = serializers.FloatField() However, when passing my dictionary into the the serializer and attempting to validate it, the serializer.errors attribute has: { "airmass_data": { "site": [ "This field is required." ] } } Is there a good way to write a set of serializers such that it deals with dynamically generated keys? I am mostly trying to write this to validate the general structure of the returned dictionary - not necessarily the keys … -

In Django template button is not working as expected
In my project, I used the function toggle_follow which is working fine but in my template on the first click nothing changed in the second click it turns to unfollow as expected, and after again clicking it becomes to follow which is also expected. After that, it doesn't work. Though the follow shows in the following tab and update the list but the button stopped working. The problem is, the follow counter is not updating properly and not storing into database as If I follow someone and another user visit the same profile, the user by default see that he is following the user also whom I'm following which is not as expected. However, for first three time the result is expected and working properly. my models.py >>> class Follow(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE, related_name="follow") followed = models.ForeignKey(User, on_delete=models.CASCADE, related_name="followers") class Meta: verbose_name = "following" verbose_name_plural = "followings" unique_together = ["user", "followed"] def str(self): return f"{self.user} is following {self.followed}" def followed_post(self): return self.followed.posts.order_by("-date").all() my views.py >>> @login_required def toggle_follow(request, id): if request.method == "GET": return HttpResponse(status=405) if request.method == "POST": try: follow_obj = Follow.objects.get(user=request.user.id, followed=id) except Follow.DoesNotExist: try: to_follow = User.objects.get(pk=id) except User.DoesNotExist: return HttpResponse(status=404) else: new_follow_obj = Follow(user=request.user, followed … -

Django: Is there a way to let Heroku manage js and css files but let images come from S3 bucket?
I am buiding an app with django. I uploaded all my static files to an S3 bucket. Js and css files included. And in DEBUG = False I'm getting my files from that bucket I am hosting my app in Heroku, so I couldn't serve images from there. That's way I'm getting my images from an externar source. But now I'm facing some problems when I have all my files in the S3 bucket. And I also think it's not really necessary to serve js and css from there too. So is there a way to let images come from the S3 bucket but serve my js and css files from the host (heroku)? -
Django filtering ForeignKey
This is view: def post(self, request): author_request = request.data.get("author") queryset = Book.objects.filter(author=author_request) serializer = BookSerializer(queryset, None) return Response(serializer.data, HTTP_200_OK) This is model: class Author(models.Model): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) full_name = models.CharField(max_length=255, null=True, blank=True) about = models.TextField(null=True, blank=True) created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now=True) def __str__(self): return self.full_name class Meta: verbose_name = 'Author' verbose_name_plural = 'Authors' So, when i try to filter the book by author i get the error. The error tells me that the POST data that i entered which is "Aleksa Petrovic" a name of a author that exists in the database is not an UUID. So when i filter it, it filters by UUID and i want it to filter by "full_name"
