How can an object be deleted if another one is emty?
So, I am a begginer coding an e-commerce project on Django. I've managed to add a "delete item"function to remove items from the cart. However, when the item is removed, the order isn't. OrderItem and Order are 2 sepparate models, I'd like so that when an OrderItem i fully deleted and the cart is empty, for the order itself to be deleted too. I'll attach de code for the models and the functios. Order mode: class Order(models.Model): customer = models.ForeignKey(Customer, on_delete=models.SET_NULL, null=True, blank=True) date_ordered = models.DateTimeField(auto_now_add=True) complete = models.BooleanField(default=False) transaction_id = models.CharField(max_length=100, null=True) def __str__(self): return str(self.id) @property def get_cart_total(self): orderitems = self.orderitem_set.all() total = sum([item.get_total for item in orderitems]) return total @property def get_cart_items(self): orderitems = self.orderitem_set.all() total = sum([item.quantity for item in orderitems]) return total OrderItem model: class OrderItem(models.Model): product = models.ForeignKey(Product, on_delete=models.SET_NULL, null=True) order = models.ForeignKey(Order, on_delete=models.SET_NULL, null=True) quantity = models.IntegerField(default=0, null=True, blank=True) date_added = models.DateTimeField(auto_now_add=True) @property def get_total(self): total = self.product.price * self.quantity return total The function for deleting the items: def eliminaritem(request, id): if request.method == "POST": item = OrderItem.objects.get(product = id) item.delete() return render(request, "store/deletecartitem.html", {'item': item}) if OrderItem.objects.all == None: customer = customer = request.user.customer order = Order.objects.all(customer = customer) order.delete() The first … -
Django ListView filter and orderby with pagination
I'm building a simple e-commerce website. I'm using ListView to represent home page of website that displays items. I want to be able to filter Items by their category and be able to order by some factor (for example price). By default it should show all items. And if there is another page of items of given kind it should keep filter. Also an explanation would be greatly appreciated. My code: views.py from django.views.generic import ListView, from .models import ShopItem class HomeView(ListView): model = ShopItem paginate_by = 2 template_name = "home-page.html" def get_queryset(self): q = self.request.GET.get('filter', '') if not q: return self.model.objects.all() return self.model.objects.filter(category=q) models.py from django.db import models class ShopItem(models.Model): id = models.AutoField(primary_key=True) title = models.CharField(max_length=100) description = models.TextField() category = models.CharField(max_length=15) price = models.FloatField() discount_price = models.FloatField(blank=True, null=True) slug = models.SlugField() home-page.html <li class="nav-item active"> <a class="nav-link" href="/">All <span class="sr-only">(current)</span> </a> </li> <li class="nav-item"> <a class="nav-link" href="#">Necklace</a> </li> <li class="nav-item"> <a class="nav-link" href="#">Earrings</a> </li> <li class="nav-item"> <a class="nav-link" href="#">Bracelets</a> </li> {% if is_paginated %} <nav class="d-flex justify-content-center wow fadeIn"> <ul class="pagination pg-blue"> {% if page_obj.has_previous %} <li class="page-item"> <a class="page-link" href="?page={{ page_obj.previous_page_number }}" aria-label="Previous"> <span aria-hidden="true">&laquo;</span> <span class="sr-only">Previous</span> </a> </li> {% endif %} {% for page in page_obj.paginator.page_range … -

Tag of a Django Template from a variable
I need to do a form with Django which can have both "select" or "input" tags, depending on a variable. Here's how I pass the variable to the html (file: views.py): from django.shortcuts import render, redirect from direzione.models import Jobs, JobType from django.contrib.auth import logout from django.contrib.auth.decorators import login_required from django.template.defaulttags import register from login import views as lgnwv import json # Create your views here. @register.filter def get_item(dictionary,key): return dictionary.get(key) @login_required(login_url=lgnwv.login) def fattura(request): if request.method =="POST": if request.POST.get('logout') == 'logout': logout(request) return redirect(lgnwv.login) else: datas = JobType.objects.get(jobType=0) dts = json.loads(datas.inputs) job = Jobs.objects.get(id_job=1) jobName = job.nome jobHead = datas.headNome return render(request, 'fattura/fattura.html', {"dts": dts, "inputs":dts["inputs"], "jobName":jobName, "jobHead":jobHead}) So, the variable that contains the string 'input' or 'select' is into the dict inputs (the one that's looped) This is my form: <div class="form" style="height:{{ dts|get_item:'height' }}px"> <div class="title">Crea Fattura</div> <div class="subtitle">Compila tutti i campi correttamente.</div> {% for key, value in inputs.items %} <div class="input-container ic2"> <{{ value|get_item:'tag' }} id="{{ key }}" autocomplete="off" class="input" type="{{ value|get_item:'inputType' }}" placeholder=" " /> <div class="cut" style="width: {{ value|get_item:'cutWidth' }}px"></div> <label for="{{ key }}" autocomplete="off" class="placeholder">{{ value|get_item:'placeholder' }}</label> </div> {% endfor %} <button type="text" class="submit">Invia</button> </div> The line where I have the problem is the … -

How to redirect logged-in user to a specific page in Django
Code was not written by me, I am just trying to find a way to redirect a logged-in user if he wants to access a certain page in a Python/Django script. I can actually do it in Templates but as far as I understand this logic should be implemented in Views. Example: Already logged-in user tries to access to signup page by typing the signup page url/path. In this case, I would like to redirect the user to the homepage (/). What I tried with very very basic Python and zero Django knowledge?. Inside the views/auth.py (SignUp class), I try to write a get method and check if user is already authenticated, redirect him to a specific page. And actually it worked for already logged-in users but if a guest/visitor wants to open the sign up page then it returns an error: "views.auth.SignUp didn't return an HttpResponse object. It returned None instead." class SignUp(FormView): form_class = SignUpForm template_name = "xxx/registration/signup.html" # I added def get(self, request, *args, **kwargs): if request.user.is_authenticated: return redirect('/') def form_valid(self, form): user = form.save(commit=False) user.username = form.cleaned_data.get("username").lower() user.theme = get_theme_from_cookie(self.request) user.save() send_email_confirmation(user, user.email) notifications.info( self.request, _( "confirmation message.." ), ) return redirect("login") and here is the … -

I have implemented this in django itself using channels package (created consumers, routing, templates, js files and some other stuff), but I am stuck now, don't know what to do. The goal is that I have to make an API in DRF and Flutter devs should link it. Here is my models.py class Thread(models.Model): first_person = models.ForeignKey(User, on_delete=models.CASCADE, null=True, blank=True, related_name='thread_first_person') second_person = models.ForeignKey(User, on_delete=models.CASCADE, null=True, blank=True, related_name='thread_second_person') updated = models.DateTimeField(auto_now=True) timestamp = models.DateTimeField(auto_now_add=True) objects = ThreadManager() class Meta: unique_together = ['first_person', 'second_person'] class ChatMessage(models.Model): thread = models.ForeignKey(Thread, null=True, blank=True, on_delete=models.CASCADE, related_name='chatmessage_thread') user = models.ForeignKey(User, on_delete=models.CASCADE) message = models.TextField() timestamp = models.DateTimeField(auto_now_add=True) consumers.py import json from channels.consumer import AsyncConsumer from channels.db import database_sync_to_async from django.contrib.auth import get_user_model from chat.models import Thread, ChatMessage User = get_user_model() class ChatConsumer(AsyncConsumer): async def websocket_connect(self, event): print('connected', event) user = self.scope['user'] chat_room = f'user_chatroom_{user.id}' self.chat_room = chat_room await self.channel_layer.group_add( chat_room, self.channel_name ) await self.send({ 'type': 'websocket.accept' }) async def websocket_receive(self, event): print('receive', event) received_data = json.loads(event['text']) msg = received_data.get('message') sent_by_id = received_data.get('sent_by') send_to_id = received_data.get('send_to') thread_id = … -
Run a function on server exit Django
I have a Django Server which runs some background jobs on startup. Code provided below- class ApiConfig(AppConfig): default_auto_field = 'django.db.models.BigAutoField' name = 'api' def ready(self): run_once = os.environ.get('CMDLINERUNNER_RUN_ONCE') if run_once is not None: return os.environ['CMDLINERUNNER_RUN_ONCE'] = 'True' from . import bgJobs stop_run_continuously = bgJobs.run_continuously() and the background Job looks something like this def run_threaded(job_func,*args,**kwargs): job_thread = threading.Thread(target=job_func,args=args,kwargs=kwargs) job_thread.start() def run_continuously(interval=1): cease_continuous_run = threading.Event() class ScheduleThread(threading.Thread): @classmethod def run(cls): while not cease_continuous_run.is_set(): schedule.run_pending() time.sleep(interval) continuous_thread = ScheduleThread() continuous_thread.start() return cease_continuous_run def printTest(Text): time.sleep(10) schedule.every(10).seconds.do(run_threaded,printTest,Text="Texts") The bgJob is a demo one. Question:-The background jobs run even after I close the server. I have to run the stop_run_continuously.set() when the server exits to stop it but couldn't find some way to do this. My preference is to do this in django only. Note:- If there is a better way of running the job then you can also provide that -
Can't login after changing base user model to custom one
I have recently changed my user model to a custom one and can't login to both admin (with superusers) and website (wit normal users) anymore. I use the email field for authentication. I guess there's something I didn't consider but since there are no errors I dont know where to search. Note: When I try to login (admin or website) the login form just refreshes with empty inputs, so I guess the form is not valid? If so, why? # models.py from django.core.mail import send_mail from django.db import models from django.contrib.auth.models import User from django.db.models.signals import post_save from django.dispatch import receiver from django.contrib.auth.models import AbstractBaseUser from django.contrib.auth.models import PermissionsMixin from django.contrib.auth.models import BaseUserManager class UserProfileManager(BaseUserManager): """ Manager for user profiles """ def create_user(self, email, name, password=None): """ Create a new user profile """ if not email: raise ValueError('User must have an email address') email = self.normalize_email(email) user = self.model(email=email, name=name) user.set_password(password) user.save(using=self._db) return user def create_superuser(self, email, name, password): """ Create a new superuser profile """ user = self.create_user(email, name, password) user.is_superuser = True user.is_staff = True user.save(using=self._db) return user class UserProfile(AbstractBaseUser, PermissionsMixin): """ Database model for users in the system """ email = models.EmailField(max_length=255, unique=True) name = models.CharField(max_length=255) is_staff … -

How to render the emoji API in Django template
