Unable to login to Django admin website after setting SESSION_COOKIE_NAME="__Host-Session"
I have a Django application running locally. I wanted to change the SESSION_COOKIE_NAME to something with the prefix "__Host", so cookies are only sent to the host that initially set the cookie. However, I am unable to login into the admin page or the application after I do that. Setting SESSION_COOKIE_NAME to any other name works well, just not with prefix "__Host ". Any idea what might be causing this? Could the fact that I am running it locally(so HTTP instead of HTTPS) have something to do with it? -

Login function not working in Django Python project
Description: I am working on a Django project which is a virtual wallet with admin and multi user login with interchangeable amounts. I am having issues with the login functionality. I have cloned the repository from GitHub (https://github.com/btmstage3/virtual-wallet-with-admin-and-multi-user-login-with-interchangeble-amounts-in-python.git) and followed the installation instructions in the README file. However, when I try to login with the default superuser credentials (username: admin, password: password), I get an error message saying "Invalid login credentials". I have checked my code and compared it to the code in the repository, but I cannot figure out what is causing the issue. I am new to Django and would appreciate any help or advice on how to fix this issue. Here is the code for my login view function: python from django.shortcuts import render, redirect from django.contrib.auth import authenticate, login, logout from django.contrib import messages def user_login(request): if request.method == 'POST': username = request.POST.get('username') password = request.POST.get('password') user = authenticate(request, username=username, password=password) if user is not None: login(request, user) return redirect('home') else: messages.error(request, 'Invalid login credentials') return redirect('login') return render(request, 'login.html') I would appreciate any suggestions or guidance on what could be causing this issue.

Display image in template based on ID of image in Django
I'm building a small page in Django. For this page I have a model that stores images for the webpage. These can be updated in the future. I'm struggling to display the images properly. My model looks like this: def image_upload_handler(instance, filename): fpath = pathlib.Path(filename) new_fname = str(uuid.uuid1()) return f"{instance.imgLocation}/{new_fname}{fpath.suffix}" #models class coreImage(models.Model): imageName = models.CharField(max_length=255, blank=False) image = models.ImageField(upload_to=image_upload_handler) imgLocation='headerImages' def __str__(self): return f"{self.imageName} in {self.imgLocation}" The view looks like this: def core_view(request): context = { 'image' : coreImage.objects.all(), 'drinks' : DrinkRecipe.objects.all(), 'ingredients' : Ingredient.objects.all() } return render(request,'rhumSite/home.html',context=context) How do i get image with id=1 to show up in my template? I've tried this: <img class='page-img' src={{image.image(id=1).url}}> As you have guessed, this doesnt work. What am I doing wrong? Thanks in advance. -

Adding an element to a ManyToManyField in Django not saved?
While I was making one of my first projects on Django, I had to create two models. One of them, Image, has a field tags which is a ManyToManyField referring to the other model, Tag. I wanted to add elements to the tags field with a post_save signal. No problem occur during this process (in particular, the elements I want to add exist), but at the end no element is added. Here is a snipplet of the models.py I've written so far : # (Importing the modules ...) class Image(models.Model): id = models.AutoField(primary_key=True) image = models.ImageField(upload_to="media/") tags = models.ManyToManyField("Tag", related_name="images", blank=True) class Tag(models.Model): id = models.AutoField(primary_key=True) name = models.CharField(max_length=255) def __str__(self): return self.name @receiver(post_save, sender=Image) def create_tags(sender, instance, created, **kwargs): if created: print(f"Before : {instance.tags.all()}") tag = Tag.objects.first() instance.tags.add(tag) instance.save() print(f"After : {instance.tags.all()}") When I add an element through the admin panel, the following is printed : Before : <QuerySet []> After : <QuerySet [<Tag: myfirsttag>]> But if I check the freshly added element, no tag is selected. Could you please help me figuring out what I am doing wrong ? Thanks in advance and have a nice day ! -

How can i auto fill a field and make it readonly in django admin

Can I use set operation in django template(3.x)?

So does {% if request.path in signup, login, update, change_password %} and {% if request.path in "signup, login, update, change_password" %} doesn't work. Passing boolean value True from view functions and using it in the if tag works, but it seems inefficient: it is hard to maintain. {% if my_var %} document.querySelector('h6').textContent = '' {% endif %} How can I make it more efficient? Either in template or view level. -

CREATE TABLE AS SELECT in Django
I would like to run a CTAS query in django with a postgres database. In other words, I'd like to create a table from queried results. I'd like to create a new table using columns from multiple models so when I use it in a view, I don't have to run multiple queries, I can just use the new table. It would be temporary and created every time the view is called, so as the data updates, the table generated is up to date as well. I know Django does not have any built in functionality for that but does anyone know how to do something similar? Currently I am using one table and having to do a filter function on every row to combine multiple tables of data. I am using django version 4.1.5 and postgres backend.
