I have a function like this in views.py: def signin(request): if request.method == 'POST': uname = request.POST['username'] pwd = request.POST['password'] #and other code And then i have another function like this: def reservations(request): try: c = Utilisateur.objects.get(username = uname) reserve = Reserve.objects.get(client = c) return render (request, 'reservation.html', {'reserve':reserve}) except: return HttpResponse ('you have no reservations!') And i want to use the "uname" variable of the first function but it doesn't work any solution? -
what does models.Models.None mean in django templates?
I have three models. A User model, which is just the basic django User model, so I won't add the code for it. An Account model (which is a CustomUser model/extension of the basic django User): class Account(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) joined_groups = models.ManyToManyField(Group) And, finally, I have a Group model: class Group(models.Model): leader = models.ForeignKey(User, on_delete=models.CASCADE, null=True) description = models.TextField() topic = models.CharField(max_length=55) joined = models.ManyToManyField(User, related_name='joined_group') def __str__(self): return self.topic Now I'm trying to render my User information as well as the Account information in my django templates. Inuser_details.html I have the following account info written out: <div>Username: {{user.username}}</div> <div>Groups Joined: {{user.account.joined_groups}}</div> However, what's rendering is Groups Joined: groups.Group.None I don't really know what this means or why it's happening, and I also don't know how to render the Groups my User has joined. Any help would help. Thanks. -

Django REST Framework router seems to be overriding my explicitly defined path in URLpatterns
new to coding so I'm sure this is a simple problem but I can't seem to figure it out. I've abbreviated the code so it's simpler to see the problem. urls.py router = routers.DefaultRouter() router.register(r'clients', views.ClientViewSet, basename='client') urlpatterns = [ #Bunch of other paths here. path('client/<int:pk>/contacts', login_required(views.contacts_by_client), name="client-contacts"), path('api/', include(router.urls)), ] views.py def contacts_by_client(request, pk): client = Client.objects.get(id=pk) contact_list = Contact.objects.filter(user=request.user, client=pk) context = { 'contacts': contact_list, 'client': client } return render(request, 'pages/contacts-client.html', context) class ClientViewSet(viewsets.ModelViewSet): serializer_class = ClientSerializer permission_classes = [permissions.IsAuthenticated] @action(detail=True, methods=['get'], name="Contacts") def contacts(self, request, pk=None): # Bunch of code here. My suspicion is that the router is creating a route name called "client-contacts" based on the action created in views.py, however, I don't understand why it would take precedence over the explicitly labeled url pattern that comes before it. I know I must be missing something super simple, but I can't figure it out. Thank you all for your help! -

Django: how to create slugs in django?
i want to create a slug in django, i have used the slug = models.SlugField(unique=True). Now when i create a post with a slug of learning-to-code it works, but if i create another post with the same slug learning-to-code, it shows an error like Unique Constraint Failed. But i want to create posts with the same slug, is there a way to make slugs unique only to the time a post was created? this is how my model looks class Article(models.Model): title = models.CharField(max_length=200) description = models.TextField(blank=True, null=True) slug = models.SlugField(unique=True) user = models.ForeignKey('userauths.User', on_delete=models.SET_NULL, null=True) How can i go about achieving this? -

Struggling with aggregate and subtraction in Django and PostgreSQL
So I am having an issue with querys (getting the sum of an item(aggregate) and subtracting. What I am trying to do is 10 (soldfor) - 2 (paid) - 2 (shipcost) = 6 The issue is, if I add another (soldfor) (paid) or (shipcost) = it will add all of them up so the profit becomes double. Another example, If I have an item with the (paid) listed at 3.56 and another item with the same (paid) int, it subtracts the two from each new row. I have tried two queries and I cannot get them to work. What I get: 10 (soldfor) - 2 (paid) - 2 (shipcost) = 12, because two fields have the same exact input. So basically, if the two fields have the same number it adds or subtracts them to every row that have the same field with the same number. models.py class Inventory(models.Model): product = models.CharField(max_length=50) description = models.CharField(max_length=250) paid = models.DecimalField(null=True, max_digits=5, decimal_places=2) bin = models.CharField(max_length=4) listdate = models.DateField(null=True, blank=True) listprice = models.DecimalField(null=True, max_digits=5, decimal_places=2, blank=True) solddate = models.DateField(null=True, blank=True) soldprice = models.DecimalField(null=True, max_digits=5, decimal_places=2, blank=True) shipdate = models.DateField(null=True, blank=True) shipcost = models.DecimalField(null=True, max_digits=5, decimal_places=2, blank=True) created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateField(auto_now=True) def … -
Query Django data base to find a column with a specific value and update that column value
I have tried very hard to understand how to update my data base, but struggling to even print out the value of the data returned. My code in views.py: #SET THE PLACEHOLDER DATE AND TIME AS A STRING AND CONVERT TO DATETIME #QUERY THE DATA BASE TO FIND THE ROW WHERE END_END_TIME = PLACEHOLDER DATE AND TIME #OUTPUT THE DATA TO THE TERMINAL #UPDATE THE END_DATE_TIME TO CURRENT DATE AND TIME date_time_placeholder = "2023-01-01 12:00:00" datetime.strptime(date_time_placeholder, "%Y-%m-%d %H:%M:%S").date() get_value = logTimes.objects.get(end_date_time = date_time_placeholder) print(get_value) The output: logTimes object (155) I can see in the admin site the code is working, it is finding the correct row, but I am not sure how to print the column data to the terminal instead of the just the object and ID. What I am trying to achieve ultimately is to update the end_date_time in this row to the current date and time using datetime.now(), I am not having any success, not for the lack of trying for hours. Any help is appreciated. -

What authentication actually does? [closed]

Is there a way to save a Django object and update other objects without a recursion loop?
I have a Django model: class Event(models.Model): fk = models.ForeignKey(Foreign, null=True, on_delete=models.SET_NULL) display = display = models.BooleanField(default=True) ... I'd like to override the save method to turn off display for other events that share the fk value. However, I keep reaching infinite recursion loops because if I override the save method and then save the other objects, it keeps calling the function. Is there a way to only run the save method on the first object that's saved and not keep creating recursive instances? -

error django.db.utils.IntegrityError: NOT NULL constraint failed

Reference a django variable in html to perform a function
I am trying to to output a function on the string that a user selects in a dropdown form. I have a custom template tag that works when you feed it the right variable, but am not sure how to pass on the selected item to it. <select> {% for drink in drinks %} <option id="dropdown" value="{{drink.drink_name}}">{{drink.drink_name}}</option> {% endfor %} </select> <li>{{drink.drink_name|drink_joins}}</li> I know the list gives me an error because drink.drinkname is out of the loop but this is the logic I'm going for. Also fetching the selected value with JavaScript (document.getElementById("dropdown").value) only gives me the first item from the dropdown so that is a problem too. Any remedies? -
Django container is rejecting nginx containers traffic

How to get difference between two annotate fields in django orm
