Generating token in django
I'm very new to django. I'm working on resetting the password with PasswordResetView. I've made all the necessary configurations. All the views are working properly(reset,done,confirm,complete) but the email is not being sent. I'm using file based method. The mail content is also stored in a text file successfully. The text file MIME-Version: 1.0 Content-Transfer-Encoding: 8bit Subject: Password reset on 127.0.0.1:8000 From: webmaster@localhost To: user1991@gmail.com Date: Fri, 08 May 2020 13:07:44 -0000 Message-ID: <158894326451.7060.3441580324173819052@DESKTOP-G46QTJT.localdomain> You're receiving this email because you requested a password reset for your user account at 127.0.0.1:8000.

Atleast I want to know how to generate the one time url alone like the one django created automatically. -
Django accessing sublass of model within a form
I have different models in a class and subclasses of them - and I want to create a form for all of them - I know I could do it with a single page for all of them, but is there a smart way to this? models.py: class ProductBase(models.Model): name = models.CharField('Name', max_length=120) price = models.DecimalField("Per part", decimal_places=2, max_digits=6) class Software(ProductBase): link = models.URLField('Download Link', blank=True) class Hardware(ProductBase): shipping_cost = models.DecimalField("UPS", decimal_places=2, max_digits=6) forms.py: class ProductForm(ModelForm): required_css_class = "required" class Meta: model = Product fields = "__all__" views.py: def add_part(request): submitted = False if request.method == "POST": form = PartForm(request.POST) if form.is_valid(): form.save() return HttpResponseRedirect("/add_product/?submitted=True") else: form = PartForm() if "submitted" in request.GET: submitted = True return render(request, "gap/add_product.html", {"form": form, "submitted": submitted}) add_product.html: {% extends 'base.html' %} {% block content %} {% if submitted %} <p class="success">Part was saved successfully.</p> {% else %} <form action="" method="post" novalidate> <table> {{ form.as_table }} <tr><td><input type="submit" value="Submit"></td></tr> </table> {% csrf_token %} </form> {% endif %} {% endblock content %} This way I create the form to save a product in the database in the probably simplest way.

Django 2.2 Deleting any user on the admin interface raises this error

I'm trying to deploy Django on Docker in AWS Lightsail, and the pages are stuck loading with no connection to server
I have been trying to deploy a Django app on Lightsail with Gunicorn, NginX, and Docker. I've looked at multiple tutorials, all without success. I'm not familiar with most of the concepts, and I've pretty much been following blindly. So far, everything seems to work on the server itself, but I can't see the results on a webpage. I have configured it for "production" (not sure if I'm even doing it right), and I've added a record to my domain which redirects to this server. The webpage just buffers continuously, even when I try to set it to port 8000 (for development). I think I've gotten a few instances where I saw a "301 5" permanently moved log show up on the docker-compose logs, but that's about it. Here are the Dockerfile, docker-compose.yml, and nginx conf.d file (which are probably the most important. docker-compose.yml version: '3.7' services: web: build: environment: - ENVIRONMENT=production - SECRET_KEY=NOT IMPORTANT - DEBUG=0 - EMAIL_HOST_USER=EMAIL - EMAIL_HOST_PASSWORD=PASSWORD volumes: - .:/code - static_volume:/code/staticfiles depends_on: - db networks: - nginx_network - db_network db: image: postgres:11 env_file: - config/db/db_env networks: - db_network volumes: - db_volume:/var/lib/postgresql/data nginx: image: nginx:1.17.0 ports: - 80:80 volumes: - ./config/nginx/conf.d:/etc/nginx/conf.d - static_volume:/code/staticfiles depends_on: - web … -

I am new to Django, I want to receive a value from the URL and then use it in a filter, but I am having this problem. where value is a field of a model, in the view.py class ModelNumber(generics.ListAPIView): permission_classes = [ IsAuthenticated, ] serializer_class = ModelSerializer def get_queryset(self): queryset = Model.objects.all() value = self.request.query_params.get('value') return Model.objects.filter(value = value) at urls.py path('model_number/(?P<receipt_ballot>\w+)$', views.ModelNumber.as_view()), and Model.py class Model(models.Model): value = models.CharField("Number Value", max_length=12, null=True) -
can anyone make me understand simply
def single(request,slug): pro = products.objects.get(slug=slug) images=productImage.objects.filter(product=pro) template = 'products.html' context = {'pro': pro,'images':images} return render(request, template, context) class products(models.Model): title = models.CharField(max_length=120) desc = models.TextField() price = models.DecimalField(max_digits=10, decimal_places=2, default=29.99) sales_price = models.DecimalField(max_digits=10, decimal_places=2, blank=False, null=False, default=0) slug = models.SlugField(unique=True) timestamp = models.DateTimeField(auto_now_add=True, auto_now=False) update = models.DateTimeField(auto_now_add=False, auto_now=True) active = models.BooleanField(default=True) def __str__(self): return self.title def get_price(self): return self.price def get_absolute_url(self): return reverse("single", kwargs={"slug": self.slug}) class productImage(models.Model): product = models.ForeignKey(products, on_delete=models.CASCADE) image = models.ImageField(upload_to='images/') featured = models.BooleanField(default=False) Thumbnail = models.BooleanField(default=False) active = models.BooleanField(default=True) update = models.DateTimeField(auto_now_add=False, auto_now=True) def __str__(self):`enter code here` return self.product.title what is the task of pro = products.objects.get(slug=slug) and images=productImage.objects.filter(productt=product). what is the difference between using product.productImage_set.all rahter than productImage.objects.filter(product=product) -
Restrict url base Django Api with drf
Hi I want to filter one of my Api models by one field. Building the queryset for the view I need to use the whole model using model.objects.all() and the model serializer. Once I set the filterset which the parameter I want to filter. It filters correctly when I make the consult directly but the problem is when I access to the url for the filter, it by default shows me all the elements of this models and if I search for an element that not exist it also shows al the elements. How can do to make it show me the elements that I'm searching, restrict the url base and if the element doesn't exists in the database just show it empty. Any idea? Thanks -
NoReverseMatch at /each_product/1/
I have an anchor tag in an html template as : <a href="{% url 'each_product' pk=product.id %}"> View</a> In urls.py i have set up the url path as follow for this: path("each_product/<int:pk>/", views.each_product, name="each_product") And in view i have defined the function each_product as: def each_product(request, pk): return render(request, "store/view_each_product.html") I have template named as view_each_product.html. Whenever i try to click view tag , it says "Reverse for 'each_product' with no arguments not found. 1 pattern(s) tried: ['each_product/(?P[0-9]+)/$']" But , when i try to render other templates such as home page , or any other than this ! It doesn't show error.
