Django Celery: Clocked task is not running
In a Django app, I have a form that schedules an email to be sent out. It has four fields: name, email, body, send_date. I want to dynamically create a Celery task (email) to run another Celery task at the designated time. I have been able to send out the email at regular intervals (every 30 seconds) based on the form using the following code: schedule, _ = IntervalSchedule.objects.update_or_create(every=30, period=IntervalSchedule.SECONDS) @shared_task(name="schedule_interval_email") def schedule_email_interval(name, email, body, send_date): PeriodicTask.objects.update_or_create( defaults={ "interval": schedule, "task": "email_task" }, name="Send message at interval", args=json.dumps(['name', 'test@test.com', 'body']), ) However, when I have tried to schedule a task to run at a specific time (3 minutes later from the current time) via ClockedSchedule, Celery beat records the tasks and saves all the relevant settings. However, it never actually sends an email. clocked = ClockedSchedule.objects.create(clocked_time=datetime.now() + timedelta(minutes=3)) @shared_task(name="schedule_clock_email") def schedule_email_clocked(name, email, body, send_date): PeriodicTask.objects.create( clocked=clocked, name="Send message at specific date/time", task="email_task", one_off=True, args=json.dumps(['name', 'test@test.com', 'body']), ) I eventually want to dynamically set the clocked field based on the datetime the user enters into the form, so the current code is just trying to test out the way Celery works. I think I'm missing something about how this works, though. … -

I have added login with Google Button on my login page, but when I click on that button, I am redirecting to accounts/google/login where it's asking for conformation to continue and menu with sign-in and sign-out.

How to ensure fetch GET request runs after database updated?
I am having trouble ensuring that my GET request in Javascript runs after my PUT. Sometimes the JSON promise returns with updated data sometimes it does not! It appears to be random. It always displays correctly upon page reload. I am getting a "Fetch failed loading: PUT" error in my console despite the database being updated successfully. I know of await/async but was unclear if this was my solution and if so how I would implement with the correct syntax. Here is my JS: function like(id) { like_button = document.getElementById(`like-button-${id}`); if (like_button.style.backgroundColor == 'white') { fetch(`/like/${id}`, { method:'PUT', body: JSON.stringify({ like: true }) }); like_button.style.backgroundColor = 'red'; } else { fetch(`/like/${id}`, { method:'PUT', body: JSON.stringify({ like: false }) }); like_button.style.backgroundColor = 'white'; } fetch(`/like/${id}`) .then(response => response.json()) .then(post => { like_button.innerHTML = post.likes; }); } In case it is helpful here is my view in views.py: @csrf_exempt def like(request, id): post = Post.objects.get(id=id) user = User.objects.get(username=request.user.username) if request.method == "GET": return JsonResponse(post.serialize(), safe=False) if request.method == "PUT": data = json.loads(request.body) print(data.get("like")) if data.get("like"): post.Likes.add(user) else: post.Likes.remove(user) post.save() return HttpResponse(status=204) Thank you in advance for your help! -

Is there any way to redirect to a view from a separate view with arguments for that view function in Django?
I cannot for the life of me find a way to redirect to another view with arguments for that view in Django. I've tried the django.shortcuts redirect method, but that doesn't seem to work (it seems to want to take patterns for the url pattern and not the view function. The HttpResponseRedirect function obviously doesn't work because that function just redirects to another url. What other options are there? -
Django manual migration to add group

How to use Sqlite string pattern matching from Django?
If I have a CharField in a Django model, and I try to filter it using a string pattern with the LIKE operator, such as: MyModel.objects.filter(text__like='he_lo') Django returns the error: django.core.exceptions.FieldError: Unsupported lookup 'like' for CharField or join on the field not permitted. However, if I use manage.py dbshell to run the raw SQL: select * from myapp_mymodel where text like 'he_lo'; it runs just fine.
