How to get the detailed page by slug and not id in Django Rest Framework class based views
I am building an API using Django Rest Framework. I have the /api/localities endpoint where all of the objects on my database are displayed. Now I want to create the endpoint for a single page of a particular locality, and I want to make it by slug and not id for example /api/localities/munich. I am using Class based views and right now I can get the single page by id, for example /api/localities/2, but I want to change that to the slug. How can I do this? Here is my code: models.py class Localities(models.Model): id_from_api = models.IntegerField() city = models.CharField(max_length=255, null=True, blank=True) slug = models.CharField(max_length=255, null=True, blank=True) postal_code = models.CharField(max_length=20, null=True, blank=True) country_code = models.CharField(max_length=10, null=True, blank=True) lat = models.CharField(max_length=255, null=True, blank=True) lng = models.CharField(max_length=255, null=True, blank=True) google_places_id = models.CharField(max_length=255, null=True, blank=True) search_description = models.CharField(max_length=500, null=True, blank=True) seo_title = models.CharField(max_length=255, null=True, blank=True) def __str__(self): return self.city serializers.py from rest_framework import serializers from .models import Localities class LocalitiesSerializers(serializers.ModelSerializer): class Meta: model = Localities fields = ( "id", "id_from_api", "city", "slug", "postal_code", "country_code", "lat", "lng", "google_places_id", "search_description", "seo_title", ) views.py from django.shortcuts import render from django.http import HttpResponse from wagtail.core.models import Page from .models import LocalityPage, Localities from django.core.exceptions import ObjectDoesNotExist from … -

How to align text or url in Django template? - Python Crash Course, Project "Learning Log"
I am creating "Learning Log" Django web-application using "Python Crash Course, 2nd edition" book. But since I reached 20th chapter of the book, I started having problems. I created a template, that displays all entries of the particular topic. On the page we have entry title, date, a button to edit it, and of course its text. Following the book, I use bootstrap4 to make pages looks more beautiful. But I would like to align the entry date and the "edit entry" url to the right side. I tried style="text-align:right;" , but it doesn't work. I am really new to web development , so I beg you to not judge me strictly :) Page with topic and its entries topic.html {% extends 'learning_logs/base.html' %} {% block page_header %} <h3>{{ topic }}</h3> {% endblock page_header %} {% block content %} <p> <a href="{% url 'learning_logs:new_entry' topic.id %}">Add a new entry</a> </p> {% for entry in entries %} <div class="card mb-3"> <h4 class="card-header"> {{ entry.title }} <small style="text-align:right;"> {{ entry.date_added|date:'M d, Y'}} <a style="text-align:right;" href="{% url 'learning_logs:edit_entry' entry.id %}">edit entry</a> </small> </h4> <div class ="card-body"> {% if entry.text|length > 500 %} {{ entry.text|linebreaks|truncatechars:500 }} <p><a href="{% url 'learning_logs:entry' entry.id %}">Read more</a></p> {% … -

How to redirect Django button for loop in HTML to specific HTML page for that service?
Im working on a django project but got stuck here. I have a for loop which loops through the data from a model, basically looping in services which are offered and creating buttons for these. I would like to redirect the button to a specific page for only this service. So basically each service offered gets an own button and if clicked gets redirected to a page for this service only. As I add the link in an anchor I don't know how to get it from the for loop in HTML doc. How should I code this to get the desired result? MODEL: class ServiceTypes(models.Model): typ = models.CharField(max_length=255, primary_key=True, blank=False) pris = models.DecimalField(decimal_places=0, max_digits=6, null=False, blank=False) beskrivning = models.CharField(max_length=255, null=True, blank=True) VIEWS: def boka_service(request): services = ServiceTypes.objects.all() return render(request, 'main/boka.html', {'services': list(services)}) THE HTML PART: {% for r in services %} <a href="{% url 'homepage' %}"> <button class="button_x"> <p style="margin-top: -60px; font-size: 15px; font-weight: bold;">{{ r.typ }} {{ r.pris }},- kr</p> <p>{{ r.beskrivning }}</p> </button></a> {% endfor %} -

django.db.utils.IntegrityError not solving this part
I need a help regarding django.db.utils.IntegrityError: I read similar questions on stackoverflow before posting a new question, but I could not find the right solution. Basically, I am following a course, let's say copy-pasting the code in models.py, serializers.py views.py And whenever I call python manage.py migrate, I get this error: django.db.utils.IntegrityError: The row in table 'LittleLemonAPI_menuitem' with primary key '1' has an invalid foreign key: LittleLemonAPI_menuitem.category_id contains a value '1' that does not have a corresponding value in LittleLemonAPI_category.id. Anyone can help, how could I fix that error? The strange part is, that I literally follow each step on the course, it isn't even my code, and I can't figure out what's wrong. I tried to delete all migration related files and db.sqlite3, but in that way I lose all the previously entered data. I tried changing the part from on_delete.PROTECT, default=1. into. on_delete.CASCADE and removing default1, but nothing worked. -
Django form start date and date validation
I am trying to validate that the end date is greater than the start date. This is a form editing an entry submitted in a previous form. The startdate field has already been populated. This function was written based on Django documentation: [https://docs.djangoproject.com/en/4.1/ref/forms/validation/] When I submit the form there is no error thrown. Is this function called simply by submitting the form? What am I missing? ` class EditForm(ModelForm): class Meta: model = Cast fields = [ 'enddate', ] def clean(self): cleaned_data = super().clean() start_date = self.cleaned_data.get('startdate') end_date = self.cleaned_data.get('enddate') if end_date < start_date: raise ValidationError("End date must be greater than start date") ` I was expecting to see the error "End date must be greater than start date" In reality, the form submits no problem with an end date that is less than the start date. -
Django relation of models
I have an e-commerce project and I stuck at admin view. I have 2 models, namely Order and OrderItem. They are connected with FK relationship, and when Order is created I create both Order and related OrderItems in my admin page. Orders in admin page: OrderItems in admin page: When I open my OrderItems, I see my OrderItem belongs to which Order. I want to add Order# to my OrderItem# list in my admin page. In other words: I want to express "OrderItem.str" = "existing OrderItem.str" + "Order.str" My desired OrderItem__str__ format is something like: OrderItem#4-Order#2 views.py file: if request.user.is_authenticated: order = Order.objects.create(full_name=name, email=email, shipping_address=shipping_address, amount_paid=total_cost, user=request.user) order_id = order.pk for item in cart: order_item = OrderItem.objects.create(order_id=order_id, product=item['product'], quantity=item['qty'], price=item['price'], user=request.user) # Update stock product = Product.objects.get(title=item['product']) product.stock_qty -= int(item['qty']) product.save() models.py file: class Order(models.Model): full_name = models.CharField(max_length=300) email = models.EmailField(max_length=255) shipping_address = models.TextField(max_length=10000) amount_paid = models.DecimalField(max_digits=8, decimal_places=2) date_ordered = models.DateTimeField(auto_now_add=True) # Foreign key (FK) # Authenticated / not authenticated_users user = models.ForeignKey(User, on_delete=models.CASCADE, null=True, blank=True) class Meta: # Update admin view label verbose_name_plural = 'Orders' # Admin list view of order records def __str__(self): return 'Order - #' + str(self.id) class OrderItem(models.Model): # Link Order to Orderitem class # … -

Obtaining a refresh token from gapi auth2
I have the following use case: I have a Django REST + Vuejs application in which users log in using Google OAuth 2. Once they've logged in, there are some actions that they might perform which require them to grant my application extra permissions, i.e. more scopes than they originally gave permission for when logging in. These applications are performed on the backend, which will send Google services requests authenticating as the users, so I need to somehow store the access tokens, which have also been granted specific scope permissions, on my backend. In order to implement this flow, I thought about following the guide on incremental auth and do the following: const option = new gapi.auth2.SigninOptionsBuilder(); option.setScope(ADDITIONAL_SCOPES_TO_REQUEST); const googleUser = auth2.currentUser.get(); const res = await googleUser.grant(options) const response = res.getAuthResponse() The response variable will hold an object which, among the other properties, has the access_token returned by Google. After that, I can issue a request to my Django backend to create an instance of some GoogleAccessToken model which will hold the token returned by Google and use it for authenticating server-to-server requests to Google services. The idea is to use it this way: from google.oauth2.credentials import Credentials from .models … -
How to properly create recursive comments in templates django?

Django ORM sort by column, descending, drop dublicates and give the top 5
I want to query the top 5 products of a table but they must be unique on the product column, when they have the same value for the column sodium.

Django: sending a POST request with Javascript, but then displaying an updated page rather than the old one

How to check password that has been hashed and salted?
In my register method, I've created a user after hashing and salting their password. And in the login method, I need to check if the user has entered the correct password. The check_password() doesn't seem to accept a salt, and when I use the default authenticate(), I get an error saying: AttributeError: 'Manager' object has no attribute 'get_by_natural_key' I'm guessing this is probably because I created a custom User model by extending AbstractBaseUser. Is there some way I can verify the password by using an existing method? Or will I have to get the salt, hash and salt the password the user just entered, and then compare with the password in the DB? My user model: class User(AbstractBaseUser): name = models.CharField(max_length=128, blank=False) created_at = models.DateTimeField(auto_now_add=True) is_admin = models.BooleanField(blank=True,default=False, verbose_name="Is admin") designation = models.CharField(max_length=90, blank=True) email = models.EmailField(max_length=160, blank=False, unique=True) USERNAME_FIELD = "email" def __str__(self): return self.name + " " + self.email Method for creating user: def register_user(self, request, **kwargs): serializer = UserSerializer(data=request.data) # handle invalid request if not serializer.is_valid(): for key, values in serializer.errors.items(): errorMsg = key + ": " + values[0].title() return Response( {"message": errorMsg}, status=status.HTTP_400_BAD_REQUEST ) name = serializer.data.get("name") email = serializer.data.get("email") password = serializer.data.get("password") user = User.objects.filter(email=email).first() … -
