How to Change the Format of a DateTimeField Object when it is Displayed in HTML through Ajax?
models.py class Log(models.Model): source = models.CharField(max_length=1000, default='') date = models.DateTimeField(default=datetime.now, blank = True) views.py The objects in the Log model are filtered so that only those with source names that match a specific account name are considered. The values of these valid objects will then be listed and returned using a JsonResponse. def backlog_list(request): account_name = request.POST['account_name'] access_log = Log.objects.filter(source=account_name) return JsonResponse({"access_log":list(access_log.values())}) dashboard.html This Ajax script is the one that brings back the account name to the views.py. If there are no valid objects, the HTML will be empty; however, it will display it like this otherwise. <h3>You scanned the QR code during these times.</h3> <div id="display"> </div> <script> $(document).ready(function(){ setInterval(function(){ $.ajax({ type: 'POST', url : "/backlog_list", data:{ account_name:$('#account_name').val(), csrfmiddlewaretoken:$('input[name=csrfmiddlewaretoken]').val(), }, success: function(response){ console.log(response); $("#display").empty(); for (var key in response.access_log) { var temp="<div class='container darker'><span class='time-left'>"+response.access_log[key].date+"</span></div>"; $("#display").append(temp); } }, error: function(response){ alert('An error occurred') } }); },1000); }) </script> My goal is to have the Date and time displayed like "Jan. 10, 2000, 9:30:20 A.M." I've tried changing the format directly from the models.py by adding "strftime" but the error response is triggered. -
Adding a custom, non-model attribute to query set in Django?
Newbie to DRF and have a model called posts. And another called user. The post object looks as follows: class Post(models.Model): """ Post model """ title = models.CharField(max_length=250) body = models.TextField() author = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE, related_name='forum_posts') parent_post = models.ForeignKey('self', on_delete=models.CASCADE, blank=True, null=True) time_stamp = models.DateTimeField(default=timezone.now) objects = models.Manager() The serializer for this model is: class PostSerializer(serializers.ModelSerializer): class Meta: model = models.Post fields = ('id', 'title', 'body', 'parent_post', 'author', 'time_stamp') extra_kwargs = {'id': {'read_only': True}, 'author': {'read_only': True}} When returning data for this model, I want to add an extra attribute to each object within the query set called "author_username". The username should be the username belonging to the post's author id. I also want to do this without modifying the model to add another attribute such as "author_username" since this'll be redundant (already have an FK for author). So, ideally, the json for an object would look like: 'post_id': 1 'post_title': 'Example post' 'post_body': 'Example post' 'author_id': 1 'parent_post_id': null 'time_stamp': '2022' 'author_username': 'testUser' How can I go about doing this? Here's my view: class PostList(generics.ListCreateAPIView): permission_classes = [IsAuthenticatedOrReadOnly] queryset = models.Post.objects.all() serializer_class = serializers.PostSerializer -

Django Channels Channels-redis How can I access the database of redis and how can I use it?
I used Django Channels for the first time and Redis for the first time through Channels. I want to use the data stored in the redis server currently in use by django or save it in the redis server.

Two django projects with common userbase , authentication and sharing of key functionalities
I'm building a Django v3.2 project that requires merging of 2 projects(social app and ecommerce) - both of which are separate open source django projects. The end goal is to share users, posts and a common user registration and authentication process and keep a common database for both. Project 1 has a 5 docker containers(api backend, worker,scheduler, sql db, redis db) and project 2 has 1 docker container(that has a frontend sandbox ecommerce website). I came across this post while searching which is similar : How to make two django projects share the same database Based on the post share above, My core question is : While I'm using 2 separate projects that run their own docker containers, what changes will I have to make so that Registration, Authentication & Users are common Functionalities are shared. Essentially, I would like to import modules from project1-->project2 and project2-->project1 and design additional functionalities as per need. I initially tried copying files from project 2 into project 1 so that the project1 social app and functionality is just extended. But I'm running into all sorts of problems. Here is the question pertaining to the same : Python3.10:ModuleNotFoundError: No module named 'commerce' -

Adding an additional key-value pair to objects in a list before passing it to a Template - Working, but I'm not sure why
New to Django and I wanted to append a key:value pair to each Job object in a Queryset/list before passing it to a template. Researching on here it says you can't just append a field, but rather need to create a new dict or could possibly add attributes or something, but messing around I got it to work great, but logically it seems it shouldn't work, and I worry I may run into problems or data inconsistency somewhere. My "jobs" view gets all Jobs currently not assigned to a User, filters out Jobs based on the current signed in Users listed skillset(a custom field for my User model), and then the functionatily I'm adding is to check the current Users schedule, and add a value "conflict":True if the schedule conflicts so I can highlight it red when rendering the list of jobs to the screen. views.py (abbreviated): def jobs (request): //get all unassigned jobs, and create a list of only jobs where the user has matching skills available = Job.objects.filter(assigned_to__isnull=True).order_by('start_time').all() available = [job for job in available if request.user.is_skilled(job)] //go through each job, make it a dict, and add "conflict":True to it if scheudle confict for job in available: if … -

How do I hit a Django-allauth login endpoint for automated testing
Context: I am creating some boilerplate automation to essentially login to a website as a restricted user and then verify that when I hit another endpoint, I get an unauthorized response. I don't have much experience with setting up an API automated testing framework from scratch, but I am using Behave and Behave-Django for all other automation. All my test data is coming from a django .env file. My current step to hit the login api as a restricted user is as follows: @given('I log in as a restricted user') def login(context, user): context.url = 'https://myurl.com' context.user_logged_in.send(user) assert context.status_code == 403 I'm pretty green when it comes to django, so if I'm not even close let me know.

Why is my else clause not working in Django?
I'm trying to create a search error for my ecommerce website. When a user inputs a search that is not in the database, it should return the search error page. Though it seems my else clause isn't working. I tried putting the else clause in the search.html page, but it keeps giving me errors and it seems when I try to fix the errors, nothing really happens, it stays the same. I expect the search_error.html page to appear when the user inputs a product name that is not in the database. Though I keep getting for example, when I type "hello," the page appears with "Search results for hello." But it should result the search_error.html page. I also tried currently a else clause in my views.py, but it shows the same thing. I think my else clause isn't working and I don't know why. My views.py: def search(request): if 'searched' in request.GET: searched = request.GET['searched'] products = Product.objects.filter(title__icontains=searched) return render(request, 'epharmacyweb/search.html', {'searched': searched, 'products': products}) else: return render(request, 'epharmacyweb/search_error.html') def search_error(request): return render(request, 'epharmacyweb/search_error.html') My urls.py under URLPatterns: path('search/', views.search, name='search'), path('search_error/', views.search_error, name='search_error'), My search.html page: {% if searched %} <div class="pb-3 h3">Search Results for {{ searched }}</div> <div … -
