How to overide the CSS of Django UserCreationForm and AuthenticationForm without losing in built functionality?
I'm using the AuthenticationForm class to log users in, and the UserCreationForm to allow users to create accounts. Everything worked when I was just rendering the default form (using {{ form.as_p }} in my HTML files. However, I wanted to make the forms look nicer so I've over ridden the forms as so: class LoginForm(AuthenticationForm): username = forms.CharField(required=True, widget=TextInput(attrs={ 'class': "block border border-grey-light w-full p-3 rounded mb-4", "name": "username", "placeholder": "Username"})) password = forms.CharField(widget=PasswordInput(attrs={ 'class': "block border border-grey-light w-full p-3 rounded mb-4", "name": "password", "placeholder": "Password"})) class RegistrationForm(UserCreationForm): email = forms.EmailField(required=True, widget=EmailInput(attrs={ 'class': "block border border-grey-light w-full p-3 rounded mb-4", "name": "email", "placeholder": "Email"})) password1 = forms.CharField(widget=PasswordInput(attrs={ 'class': "block border border-grey-light w-full p-3 rounded mb-4", "name": "password1", "placeholder": "Password"})) password2 = forms.CharField(widget=PasswordInput(attrs={ 'class': "block border border-grey-light w-full p-3 rounded mb-4", "name": "password2", "placeholder": "Confirm password"})) class Meta: model = User fields = ['username', 'first_name', 'last_name', 'email', 'password1', 'password2'] widgets = { 'username': TextInput(attrs={'class': "block border border-grey-light w-full p-3 rounded mb-4", "type": "text", "name": "username", "placeholder": "Username"}), 'first_name': TextInput(attrs={'class': "block border border-grey-light w-full p-3 rounded mb-4", "type": "text", "name": "first_name", "placeholder": "First Name"}), 'last_name': TextInput(attrs={'class': "block border border-grey-light w-full p-3 rounded mb-4", "type": "text", "name": "last_name", "placeholder": "Last Name"}), } However, … -
Use one docker container's URL into another container settings file
I have a docker compose file in which I am running two services: one is for django and another one is for keycloak. However, I want to access the keycloak through URL inside django settings file which I am trying to do by getting the IPAdress of the keycloak (docker inspect keycloak | grep IPAdress) container, but this does not work. Also I tried with http://localhost:8080/ (8080 is keycloak port) which also didn't work as well. Any suggestions or idea will be appreciated. -

Can´t Produce to topic in Kafka using docker and python

Django import ignores sys.path
A unit test module stored in /tmp is imported in my Django project. The unit test module begins like this: import tempfile import sys sys.path.insert(0, tempfile.gettempdir()) # /tmp is first in sys.path from name_like_app import foo # foo is the function to test # name_like_app.py is in /tmp # The import looks in the app instead of /tmp! The module containing foo is stored in /tmp, but happens to be named like one of the apps in my Django project. For some reason, Django looks in the app and ignores sys.path. Why does this happen? -
Django-Admin with models from external database not saving or filtering
I have a problem with a simple Django project i'm creating. What I aim with this project is administrating a database i already have with the tooling Django Admin offers. I proceed to explain what I already did and doesn't work as expected.

Django Rest Framework - Custom serializer field does not appear in attrs dict when using "create" method
I created a ModelSerializer and want to add a custom field which does not belong to my model but is shown as part of serialized data when retrieving it and behave as writeable field when create method is called. I have a problem with validate method used on data passed in POST method. The field that does not belong to my model does not appear in attr dict when passed to validate method. The field I want is teams and when model instance already exists, I want this field to use method to retrieve result data (this works fine) and when the create method is called I want it to be a writeable field.

How can I create in Django an custom absolute url for a predefined class
I need to make a blog in Django and I have a blog class declared as follows: models.py class Blog(models.Model): name = models.CharField(max_length=200, help_text='Enter name') author = models.ForeignKey(User, on_delete=models.CASCADE, null=True, blank=True) The User class is a predefined Django class. As you can see for Blogger I don't create a class but I use a default one from Django class User. In the template blog-list.html I use the following line to display the blog author with a link to the author page: <a href="/blog/blogger/{{ blog.author.id }}">{{blog.author.first_name}} {{blog.author.last_name}}</a> wiews.py class BlogListView(generic.ListView): model = Blog ordering = ['-date'] paginate_by = 5 class BloggerDetailView(generic.DetailView): model = User urls.py urlpatterns = [ path('', views.index, name='index'), path('blog/<int:pk>', views.BlogDetailView.as_view(), name='blog-detail'), path('blogs/', views.BlogListView.as_view(), name='blogs'), path('blogger/<int:pk>', views.BloggerDetailView.as_view(), name='blogger-detail'), ] My question is how can I declare a get_absolute_url for blog.author to NOT use the manual constructed /blog/blogger/{{ blog.author.id }}? -

Seeking for Faster PDF/A Verification Tool in Django
I am currently working on a Django project that involves PDF file uploading and checking whether the uploaded file is PDF/A compliant. To accomplish this, I have been using an external module, VeraPDF. However, the verification process with VeraPDF takes around 3 seconds, which I find to be quite long. Therefore, I'm reaching out to the community for suggestions on any other free external modules or libraries that could potentially speed up this PDF/A verification process in a Django environment. Any advice would be greatly appreciated. Thank you in advance. Asynchronous Batch Processing for PDF/A Verification in Django -

I it possible to integrate python with CSS, Javascript, and HTML?
I have a frontend web application built with JavaScript, HTML, and CSS. I would like to incorporate the output of a Python script into my frontend without using a server or a full backend solution. The Python script is a simple neural network, and I want to display its output in the frontend, such as showing the result as a header or plotting a graph generated by the script. I have already tried printing the output to the console from the Python script, but I need assistance with transferring that output to the frontend. Is it possible to achieve this without a server? I am open to suggestions and starting with a simpler solution, like plotting a graph generated by the Python script in the frontend. I appreciate any guidance or code examples on how to accomplish this. Thank you! I have looked into Django but I feel as if that seems too complex and more server focused for the simple task I require. -

There is a model: class ProductRating(models.Model): class Meta: indexes = [ UniqueIndex(fields=['user', 'product']), ] user = models.ForeignKey(User, on_delete=models.CASCADE) product = models.ForeignKey(Product, on_delete=models.CASCADE) grade = models.BooleanField() created_time = models.DateTimeField(auto_now_add=True, verbose_name='created_time') I want to create a row in the database with a post request class PostRatingFromUser(generics.CreateAPIView): queryset = ProductRating.objects.all() permission_classes = [IsAdminOrAuthenticatedUser, ] serializer_class = ProductRatingSerializer def post(self, request, *args, **kwargs): rating_from_db = ProductRating.objects.get(product_id=kwargs['pk'], user=request.user) if rating_from_db: rating_from_db.grade = kwargs['grade'] rating_from_db.save() else: ProductRating.objects.create(product_id=kwargs['pk'], grade=kwargs['grade']).save() return Response(status=200) But before adding, I check if there is such a database, if there is, then I just change the value of 'grade' but it gives me an error: product.models.ProductRating.DoesNotExist: ProductRating matching query does not exist. -
In Django, how can I select an object from the database and pass the parameters not to the url, but in some other better way?
I'm new to Django, in a page i have a combobox which is populated by fields from a database (simply city names). I select an object from the database with parameters which I pass to the url. I know this isn't the cleanest approach and that there is a better way. Is there a better way to populate the combobox without passing database parameters to the url? Then passing the parameters in a different and better way. How could my code take a different approach? models.py from django.db import models class City(models.Model): name = models.CharField(max_length=30) def __str__(self): return self.name forms.py from .models import City class SelectCityForm(forms.Form): city = forms.ModelChoiceField(queryset=City.objects.all()) class Meta: model = City fields = ('name') views.py def city_detail(request): form = CitySelectForm() object = None if request.method == "POST": form = CitySelectForm(request.POST) if form.is_valid(): city_id = form.cleaned_data['city'] object = City.objects.get(id=city_id) context = {'form': form, 'object': object} return render(request, 'app1/home.html', context) home.html <form action="/url-to-city_detail-view/" method="post"> {% csrf_token %} {{ form }} <input type="submit" value="Submit"> </form> urls.py from django.urls import path, include from . import views from app1.views import index from app1 import views urlpatterns = [ path('', index, name='index'), #Aggiunto per combobox path('login/', views.sign_in, name='login'), path('logout/', views.sign_out, name='logout'), path('home/', views.home, …
