Django - BooleanField - checkbox
I'm working on a web app. This web app should let people add links to a list and then press a button to open all the links at once. So far I have this: Each link can be set to either True or False, when I clink on 'open links' only the links that are set to True will open. Now, I would like to add a checkbox next to 'Delete link'. When the checkbox is ticked the value will be True and when I untick the checkbox the value will change to False. Any help will be much appreciated, thank you! My code so far: models.py from django.contrib.auth.models import User class Site(models.Model): """A site that will be opened""" name = models.CharField(max_length=200) link = models.URLField(max_length=200) selected = models.BooleanField(default=True) date_added = models.DateTimeField(auto_now_add=True) owner = models.ForeignKey(User, on_delete=models.CASCADE) def __str__(self): """Return a string representation of the model.""" return self.name forms.py from .models import Site class SiteForm(forms.ModelForm): class Meta: model = Site fields = ['name', 'link', 'selected'] labels = {'name':'Name','link': 'Link', 'selected': 'Selected'} urls.py from django.urls import path from . import views app_name = 'links' urlpatterns = [ # Home page. path('', views.index, name='index'), # Show all links. path('links/', views.links, name='links'), # Page for β¦ -

What will be the most efficient way to filter the objects in django
I am working on a basic ecommerce website.I have created a superuser page in which I would like to see all the orders as well as the order details like customer who ordered, their address etc. These are my models.py: class ShippingAddress(models.Model): customer=models.ForeignKey(Customer,on_delete=models.SET_NULL,null=True) order=models.ForeignKey(Order,on_delete=models.SET_NULL,null=True) address=models.CharField(max_length=200,null=False) email=models.EmailField(null=False) class Customer(models.Model): user=models.OneToOneField(MyUser,null=True,blank=True,on_delete=models.CASCADE) email=models.CharField(max_length=100) class Order(models.Model): customer=models.ForeignKey(Customer,on_delete=models.SET_NULL,null=True,blank=True) complete=models.BooleanField(default=False,null=True,blank=False) 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,) And this is my views.py: def superuser(request): user=User.objects.all() customer=Customer.objects.all() order=Order.objects.filter(complete=True) items=OrderItem.objects.all() shipping=ShippingAddress.objects.all() return render(request,"superuser.html",{'order':order,'items':items,'customer':customer,'shipping':shipping}) Currently in my template I am unable to iterate over the above context such that I can get all the orders and with the every order I can print their orderitems as well as shipping details as well as customer details. I tried in one way which was really in efficient that was to iterate over all orders then iterate over all orderitems and check if orderitem.order.id was equal to order.id . Please tell me what is the best method to pass the objects in context which are the most efficient for my need . And how to iterate over them in my template. Thanks -
