How do you implement Django namespaces
I have started my journey with Django and I am thoroughly loving it. I do have a question about namespaces which I hope someone will be able to help me with and explain why it works like that. I understand namespaces are used to make sure that if you have two pages with the same name that the url and reverse function points to the right page. I have been trying to implement namespaces in a test app I am writing but have not been able to do it. Here is what I have so far (This is without namespaces as I haven't been able to get it to work. Extract from app urls.py from django.urls import path, re_path from . import views urlpatterns = [ path('', views.index, name = "index"), ] project urls.py from django.contrib import admin from django.urls import path, include, re_path import gallery urlpatterns = [ path('admin/', admin.site.urls), path('accounts/', include('django.contrib.auth.urls')), path('index/', include('gallery.urls')), ] And lastly, this is my view.py file in my app folder from django.shortcuts import render from django.urls import reverse # Create your views here. def index(request): return render(request,"gallery/index.html") Any help will be appreciated -
Simple WYSIWYG image uploading
Currently I am using ckeditor to allow users to write blog posts. It does everything I want except the image uploading is awful. Users have to jump through two screen to upload an image and specify dimensions. The images don't auto scale to mobile and overall its a very poor experience. Is there a simple way to allow users to upload images or another WYSIWYG that can handle this. -
Acessing SQLite tables with Django on Ubuntu
I am following the Django official documentation tutorial on how to setup the database, provided here : https://docs.djangoproject.com/en/4.0/intro/tutorial02/ After running the code below I should have any necessary database tables according to the database settings in my mysite/settings.py. $ python manage.py migrate Now I want to check those tables through the terminal (this is my problem -> I can't). The documentation says : If you’re interested, run the command-line client for your database and type \dt (PostgreSQL), SHOW TABLES; (MariaDB, MySQL), .tables (SQLite), or SELECT TABLE_NAME FROM USER_TABLES; (Oracle) to display the tables Django created. None of those commands works on my terminal, my project is setup to be on SQlite, which is just a file on my project folder and SQLite is included in Python, so I shouldn't need to install anything else to support your database My questions is if I can ONLY run that command (.tables) on sqlite special command line and I need to install it or is there any way I can acess it with the terminal Iam using on Django. Any help will be HIGHLY appreciated. -
Django Tutorial - Testing vote(request, question_id)
I am working my way through the django tutorial and I reached part 5 - Introducing automated testing. I want to go beyond and write test for the vote method in views.py, but can't realise how to simulate the behaviour. Is there a way to do this? models.py: class Question(models.Model): question_text = models.CharField(max_length=200) pub_date = models.DateTimeField('date published') def __str__(self): return self.question_text def was_published_recently(self): now = timezone.now() return now - datetime.timedelta(days=1) <= self.pub_date <= now class Choice(models.Model): question = models.ForeignKey(Question, on_delete=models.CASCADE) choice_text = models.CharField(max_length=200) votes = models.IntegerField(default=0) def __str__(self): return self.choice_text views.py def vote(request, question_id): question = get_object_or_404(Question, pk=question_id) try: selected_choice = question.choice_set.get(pk=request.POST['choice']) except (KeyError, Choice.DoesNotExist): # Redisplay the question voting form. return render(request, 'polls/detail.html', { 'question': question, 'error_message': "You didn't select a choice.", }) else: selected_choice.votes += 1 selected_choice.save() # Always return an HttpResponseRedirect after successfully dealing # with POST data. This prevents data from being posted twice if a # user hits the Back button. return HttpResponseRedirect(reverse('polls:results', args=(question.id,))) I've tried multiple stuff in tests.py.

Can't measure the performance of serializer using cProfile
I'm trying to use cProfile to compare between serializers.ModelSerializer and serializers.Serializer according to this tutorial. Please, check out the tutorial before continuing the reading, it will be useful for you! Serializers: from django.contrib.auth.models import User from rest_framework import serializer class UserModelSerializer(serializers.ModelSerializer): class Meta: model = User fields = [ 'id', 'username', ] class UserSerializer(serializers.Serializer): id = serializers.IntegerField() username = serializers.CharField() Views: from . serializers import UserModelSerializer, UserSerializer from rest_framework.response import Response from rest_framework.views import APIView import cProfile class TestApi(APIView): def get(self, request): u = User.objects.get(username='hamza') assert u.username == 'hamza' # just to ensure it fetches the user data = UserModelSerializer(u).data cProfile.run('for _ in range(5000): data') return Response(data) In views I just create GET endpoint and try to run cProfile but this gives me an error: NameError: name 'data' is not defined but if I comment the line cProfile.run('for _ in range(5000): data') in views and try to access data and send it to the Response without using cProfile it will work fine! So the question is, Why cProfile can't see UserModelSerializer? -

Creating Gin index for Postgres stored generated column in Django
I want to setup a Postgres "stored generated columns" with indexing to have full text search on two fields of a model. I created the generated column getting help from this tutorial, but when setting gin index on the column, I get this: django.core.exceptions.FieldDoesNotExist: Article has no field named 'vector_column'. The app cache isn't ready yet, so if this is an auto-created related field, it won't be available yet. And my Article model: class Article(models.Model): title = models.CharField(...) content = models.TextField(...) class Meta: indexes = [GinIndex(fields=['vector_column'])] and my custom sql in migration file: operations = [ migrations.RunSQL( sql=''' ALTER TABLE articles_article ADD COLUMN vector_column tsvector GENERATED ALWAYS AS ( setweight(to_tsvector('english', coalesce(title, '')), 'A') || setweight(to_tsvector('english', coalesce(content,'')), 'B') ) STORED; ''', reverse_sql=''' ALTER TABLE articles_article DROP COLUMN vector_column; ''' ), ] Is it possible to set index from Django? Seems Django needs the field to be defined on the model but that's not how generated column works. If not, what's the correct way of setting the proper index (mentioned in this Postgres doc, the on at the end) in migration files? -

FilePathField for Image Path not working with Django Admin Panel
New to Django and web development in general. But I have followed a tutorial for creating my first site. Everything worked fine, until I finished it and wanted to edit the info using the Django admin panel. The main issue is that I have a model shown below that uses FilePathField to describe the image locations. The tutorial had me place the images in /home/pi/mysite/projects/static/img. from django.db import models class Project(models.Model): title = models.CharField(max_length=100) description = models.TextField() technology = models.CharField(max_length=20) image = models.FilePathField('/img') def __str__(self): return self.title #or self.title for blog posts This worked fine at first for displaying the images on the website, but once I tried to navigate to the /change/ url from the admin panel, I would get FileNotFoundError at /admin/projects/project/1/change/ [Errno 2] No such file or directory: '/img' So I looked around and found that FilePathField is an absolute path, so tried defining it absolutely with /home/pi/mysite/projects/static/img/. This stopped the error from occurring which let me at least access the /change/ url from the admin panel. The panel now showed the image field with a dropdown that I could use to choose between the different images I had up there, which were located at /home/pi/mysite/projects/static/img/. But … -
Django ManyToOne reference multiple tables
Right now I have the following model that I'd like to be used in different models (I want to store the day of the week and time in different models): class DayTime(models.Model): # Side note: I saw that there is a DurationField and # was considering using that instead of the CharField below day = models.CharField(max_length=9, choices=DaysOfWeekTypeEnum.choices) time = models.TimeField() From the docs, I'd have to create a ForeignKey field in the above model to accommodate the ManyToOne reference. Example: class DayTime(models.Model): day = models.CharField(max_length=9, choices=DaysOfWeekTypeEnum.choices) time = models.TimeField() modelA = models.ForeignKey(ModelA, on_delete=models.SET_NULL) modelB = models.ForeignKey(ModelB, on_delete=models.SET_NULL) This doesn't sound right to me. Should I create different DayTime model instead? Thanks in advance. -

Django on Heroku: How to fix Server Error 500 only when directing to one specific model of one of the apps in admin?
First off, my Django project has several apps (with several models respectively). After deploying my code on Heroku using PostgreSQL, most things are going well. But when I checked the admin page (on Heroku), every model works fine except one (the model Store in stores app). It (which should be the ListView of the Store model) shows up Server Error (500) and that's it. Then I went to my local codebase for further checking. I replicated the same steps (i.e. going to the admin page and clicking the Store model to reach the list view), but things are working just fine. Perfect list view and no errors shown on the terminal in the local server. Can anyone shed some light on my situation please? What's possibly going wrong? Thanks in advance!

Django - Filter out All Values from one Field in Model and Delete

Currently I am having trouble filtering out all values from a field in a model to delete. I know all my other code works because as a test I can do... delete = Data_Repo1.objects.all()filter(user=request.user) delete.delete() This works great when inputed into my code below. My problem is that I need to delete all data from a field called "date1" in a model called "Data_Repo1" not delete all data from all field in a model called "Date_Repo1". I have tired "values("date1")" and "values_list("date1")" in place of ".all()" in the above code but I get the error "Cannot call delete() after .values() or .values_list()". How else can I "filter" out all values from one field from one model in order to delete them?. Code Below. Thanks in advance. def deletefield_repo1(request, pk): context = {} title = get_object_or_404(Field_Repo1, pk=pk) #Title is needed to have the database value to delete context['title'] = Field_Repo1.objects.values_list('title', flat=True).filter(user=request.user).get(pk=pk) #Just to print the name fo the field to delete for the user type = Field_Repo1.objects.values_list('type', flat=True).filter(user=request.user).get(pk=pk) if request.method == "POST": title.delete() if type … -
Django User status not saving during registration
I am using abstract user model. Default is_subscriber value is false is_subscriber = models.BooleanField(default=False). But I am trying to change it ture during registration but I am not understanding why it's not changing false to ture. here is my code: models.py class UserManagement(AbstractUser): is_subscriber = models.BooleanField(default=False) class Subscriber(models.Model): user = models.OneToOneField(UserManagement, on_delete=models.CASCADE, primary_key=True) email = models.EmailField(max_length=1000) first_name = models.CharField(max_length=200) last_name = models.CharField(max_length=200) is_subscriber = models.BooleanField(default=False) forms.py class SubscriberSignUpForm(UserCreationForm): class Meta(UserCreationForm.Meta): model = UserManagement @transaction.atomic def save(self): user = super().save(commit=False) user.is_subscriber = True #here I am changing value False to True user.save() Subscriber.objects.create( user=user, email=self.cleaned_data.get('email'), first_name =self.cleaned_data.get('first_name'), last_name =self.cleaned_data.get('last_name'), ) my_group = Group.objects.get(name='SubscribersGroup') my_group.user_set.add(user) return user views.py class SubscriberSignUpView(CreateView): model = UserManagement form_class = SubscriberSignUpForm template_name = 'members/subscriber-registration.html' def get_context_data(self, **kwargs): kwargs['user_type'] = 'subscriber' return super().get_context_data(**kwargs) def form_valid(self, form): user = form.save() why is_subscriber status not changing False to True?
