Django - NoReverseMatch at /project/3/evillio
I'm working on a portfolio project and i face a strange problem when trying to list a project, ( class-based-views-DetailView). More specifically when trying to list a project for example /project/3/evillio i got following error Reverse for 'project-detail' with arguments '('', '')' not found. 1 pattern(s) tried: ['project/(?P<pk>[0-9]+)/(?P<slug>[-a-zA-Z0-9_]+)$'] but when i add a new project, i'm able to list /project/3/evillio with no problem, however i got the same error on the next project /project/4/urban. urls.py path('project/<int:pk>/<slug:slug>', WorkProjectsDetailView.as_view(), name='project-detail'), views.py class WorkProjectsDetailView(DetailView): model = Project template_name = 'work/project-detail.html' context_object_name = 'single_project' def get_context_data(self, **kwargs): context = super(WorkProjectsDetailView, self).get_context_data(**kwargs) context['next'] = Project.objects.filter(id__gt=self.kwargs['pk']).order_by('pk').first() return context detail-project.html <div class="projects-list gallery"> {% if projects %} {% for project in projects %} <div class="item brand"> <a href="{% url 'project-detail' pk=project.pk slug=project.slug %}" class="effect-ajax" data-dsn-ajax="work" data-dsn-grid="move-up"> <img class="has-top-bottom" src="{{ project.featured_image.url }}" alt="" /> <div class="item-border"></div> <div class="item-info"> <h5 class="cat">{{ project.category }}</h5> <h4>{{ project.title }}</h4> <span><span>View Project</span></span> </div> </a> </div> {% endfor %} {% else %} <div class="col-lg-8"> <p>No Projects Available</p> </div> {% endif %} </div> Any help appreciated. -
Django Try/Except CBVs dealing with query returning None?
I am trying to include some exception handling to handle queries that return None, If none is returned I just want to display a simple JsonResponse message. Working with FBVs, I've done this pretty simply. But when using class based views, my except block is not doing as I expect. class BusinessDetailView(DetailView): model = BusinessDetail def get_object(self, queryset=None): business = self.model.objects.filter(**custom filters here)).values().first() logger.debug(Business: {business}') return business def get(self, request, *args, **kwargs): try: try: business = self.get_object() except BusinessDetail.DoesNotExist: return JsonResponse({'Error': 'Business Does Not Exist.'}) return JsonResponse(company, status=200) except Exception as e: logger.error(f'Error getting business detail with error: {e}') return JsonResponse({'Error': 'Database error, return to previous page'}, status=500) In the get_object method, the logger is returning Business: None as I expect. But in the get method, the BusinessDetail.DoesNotexist is not getting hit. The last Try/Except block is the one getting hit, returning return JsonResponse({'Error': 'DB error, return to previous page'}, status=500). From my understanding, the DoesNotExist exception would catch the query returning None? But in my case this is not occurring. Any help is greatly appreciated! -

Cannot force an update in save() with no primary key
I am working with a custom build user model in Django and there was some message in the terminal at the time of migrate given in the stackoverflow link.

Security issue with custom build decorator in Django
I am working with a custom build decorator in Django. my decorators.py: from django.contrib.auth import REDIRECT_FIELD_NAME from django.contrib.auth.decorators import user_passes_test def industry_required(function=None, redirect_field_name=REDIRECT_FIELD_NAME, login_url='app2:request_login'): actual_decorator = user_passes_test( lambda u: u.is_active and u.is_Industry, login_url=login_url, redirect_field_name=redirect_field_name ) if function: return actual_decorator(function) return actual_decorator Here is_Industry is a bool value, comes from models.py. my views.py: @method_decorator(industry_required, name='dispatch') class industryDetails(DetailView): model = Industry template_name = 'app/industryDetails.html' def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) context['inserted_text'] = "inserted text from EmployeeDetails of views.py" return context in urls.py: path('industryDetails/<int:pk>/', views.industryDetails.as_view(), name='industryDetails') models.py also included if you need: class myCustomeUser(AbstractUser): id = models.AutoField(primary_key=True) username = models.CharField(max_length=20, unique="True", blank=False) password = models.CharField(max_length=20, blank=False) is_Employee = models.BooleanField(default=False) is_Inspector = models.BooleanField(default=False) is_Industry = models.BooleanField(default=False) is_Admin = models.BooleanField(default=False) class Industry(models.Model): user = models.OneToOneField(myCustomeUser, on_delete=models.CASCADE, primary_key=True, related_name='industry_releted_user') name = models.CharField(max_length=200, blank=True) owner = models.CharField(max_length=200, blank=True) license = models.IntegerField(null=True, unique=True) industry_extrafield = models.TextField(blank=True) Now my problem is, suppose a user with having primary_key=3, can easily visite another user's data having primary_key=2, by using http://127.0.0.1:8000/industryDetails/2/ (by changing the primary key in this address path). I need to stop this for my project. How can I code this in such a way that, any user can only visit his own details? -
Best approach for developing a stateful computation-heavy application with a rest-api interface using python?
I want to develop an end-to-end machine learning application where data will be in gpu-memory and computations will run on the gpu. A stateless RESTfull service with a database is not desirable since the traffic between gpu-memory and database will destroy the "purpose" of it being fast. The way I see it is that I need a way to "serve" the class (lets call it as experiment class) which has the data and the methods, then call them using rest apis. Right now I am using FastApi and initialize the experiment class in it which I believe is not optimal. My class (as well as the data) lives in FastAPI runtime. Kinda like, import experiment_class import FastApi app = FastAPI() my_experiment = expertiment_class() @app.get("/load_csv") my_experiment.load_csv("some_file_path") // do some more on the data ... There are two problems I am having a hard time with, One of them is the terminology: Is this really a stateful application ? Is there a word to describe what I am doing ? Is this a "Model, View , Controller" design, can it be a simple "Server-Client" or is it something completely different ? Do I need a "Web-server" , a "Web-framework" or a "Web-service" … -

Django E-commerce From Scratch vs Package [closed]
I'm building an e-commerce store for a startup. It's not huge - the shop will be dropping two types of t-shirts and two types of pants per month. I want to use django for back-end.

Django Rest Framework to return desired results from two models
I have two models (customer, movie) and I would like to return (movie_name, customer_name, id) when I hit the URL (api/customer/1) and when I hit the URL (api/customer/1/movies) just wanted the movie names alone. How can we achieve this ? models.py class Customer(models.Model): name = models.CharField(max_length=200, null=True) class Movie(models.Model): movie_name = models.CharField(max_length=200, null=True) customer = models.ForeignKey(Customer, null=True, on_delete=models.SET_NULL) serializers.py class CustomerSerializer(serializers.ModelSerializer): class Meta: model = Customer fields = ('id', 'name') class MovieSerializer(serializers.ModelSerializer): class Meta: model = Movie fields = '__all__' urls.py urlpatterns = [ path('admin/', admin.site.urls), url(r'^api/customers/$', CustomerSerializer.as_view(), name='customers'), ] Note: At the moment, when I hit the URL (api/customers) it returns the id, name of all the customers. Now, I would like to know, when I hit the URL (api/customer/1) how to list the same information along with movie names and when I hit the URL (api/customer/1/movies) how to just return the movie names alone? -
What is the best way to pass a parameter from views into an anchor tag?

Running "tasks" periodically with Django without seperate server
I realize similar questions have been asked however they have all been about a sepficic problem whereas I don't even now how I would go about doing what I need to. That is: From my Django webapp I need to scrape a website periodically while my webapp runs on a server. The first options that I found were "django-background-tasks" (which doesn't seem to work the way I want it to) and 'celery-beat' which recommends getting another server if i understood correctly. I figured just running a seperate thread would work but I can't seem to make that work without it interrupting the server and vice-versa and it's not the "correct" way of doing it. Is there a way to run a task periodically without the need for a seperate server and a request to be made to an app in Django? -

Django model override save() method raises error when calling super()
I have the following Django model: class TCDUser(AbstractUser): is_change_password = models.BooleanField(_("Cambiar Password?"), default=True) groups = models.ManyToManyField(Group, default=[], related_name='users', verbose_name=_("Grupos")) class Meta: verbose_name = _("Usuario") verbose_name_plural = _("Usuarios") def __str__(self): return "[{}]{}".format(self.pk, self.username) def save(self): create = True if self.id is None else False if create: self.set_password(self.password) super(CustomModel).save() And this is the serializer: class TCDUserSerializer(CustomModelSerializer): class Meta: model = models.TCDUser fields = ('id','username', 'email', 'first_name', 'last_name', 'is_staff', 'is_active', 'is_superuser', 'password', 'is_change_password', 'groups') When I send a POST to the regular DRF ModelViewSet, I get this exception: TypeError: Got a `TypeError` when calling `TCDUser.objects.create()`. This may be because you have a writable field on the serializer class that is not a valid argument to `TCDUser.objects.create()`. You may need to make the field read-only, or override the TCDUserSerializer.create() method to handle this correctly. If I remove the call super(CustomModel).save(), the exception is no more, but I need to set the password when the user is created. -
How to load static css file inside extended template

Sort objects by interaction time grouped by users in Django
I have a Django app (I use Postgresql for the database), and I have these models of Customers, Products and Transactions that are connected as follows: class Customer(models.Model): products = models.ManyToManyField(Product, through='Transaction') class Product(models.Model): ... class Transaction(models.Model): customer = models.ForeignKey(Customer, on_delete=models.CASCADE) product = models.ForeignKey(Product, on_delete=models.CASCADE) transaction_timestamp = models.DateTimeField(auto_now=True) The transaction model tracks the time when a customer interacted with a product. I have a list of user ID-s users. I want to get a list of say 1000 products they last interacted with for every customer in users. Is there any way of doing this faster than iterating all the users? I assume this might be done through Aggregation somehow, but I couldn't find anything that worked in my case. -

How to set daily Update limit on Django model
I'm new to Django. I have created one Django App where users can update their Shift Timing(Morning/Evening/General) and based on this Shift Timing I am taking real-time data from Django Model and running Linux script which will be evaluating user shift timing and allowed timing to use the application. I have used Django import and export which allow the user to upload multiple users' data by using a .xls file from the front-end. Now here I want to apply some limit for example suppose my model is having 5000 records so I want that only 50% of its records should be allowed to modified whether it is added through .xls file or by clicking on update single records(I am doing this because I don't want that more than 50% of users should update Shift Timing). Is there any easiest way to implement this requirement? I have checked https://pypi.org/project/django-limits/ (django-limits 0.0.6)but did not understood from step 3. I am adding my models.py class CTS(models.Model): AConnectID = models.CharField(max_length=100,) Shift_timing = models.CharField(max_length=64, choices=SHIFT_CHOICES, default='9.00-6.00') EmailID = models.EmailField(max_length=64, unique=True, ) Vendor_Company = models.CharField(max_length=64, ) Project_name = models.CharField(max_length=25, default="") SerialNumber = models.CharField(max_length=19, default="") Reason = models.TextField(max_length=180) last_updated_time = models.DateTimeField(auto_now=True) class Meta: ordering = ['-id'] def … -
IntegrityError UNIQUE on blog_post.slog despite creating unique slug function
I am new to django and somewhat new to python too. I am trying to create a simple blog application and as we all know you want to have unique slugs for your blog links. However I cannot seem to rid myself of this UNIQUE error. Problem description When I create a blog post I create a slug from the title. Then I see if that slug matches any others in the database. If it does, I add a little string to the end. Nevertheless, the database keeps throwing an IntegrityError. What I've tried I have been using import pdb; pdb.stack_trace() to try to trace the issue. It seems to me to happen after setting self.object.slug and then doing self.object.save(). Somehow the unique slug is may not be be being passed to save.(). But I'm not sure how to debug beyond this point. I'd appreciate help in the debugging process. The confusing thing is that I'm working from a (functioning) django blog app. I cannot find the difference between my code and that one, and I've tried changing the methods.py and views.py to match that of the other blog, and yet that app produces unique slugs and throws no errors, … -
