Mobile screen size alias links not working
ROBLEM: In Mobile screen size alias links are not working Description I have built a project (HTML, CSS, JS building tool) with https://bootstrapshuffle.com/ I have exported the project Put it in to a django project I have added a few extra buttons to the middle of the screen that are fusions as alias on the landing page. ERORR: This exported project perfectly works with all the buttons when it is in Desktop screen size or tablet screen size (both cases the original builder reorganizes the components). But when I shrink the screen size to the size of a mobile and it reorganizes the components it leaves these alias buttons that worked in both tablet and desktop mode but does not in this mobile screen size. I have read the following projects and I probably have something similar Href links do not transpire/work at mobile size screen media queries not working on mobile screen size Links not working on site when screen size is reduced The only issue is that I have that the downloaded project from the online editor only given me a bootstrap.min.css and bootstrap.min.css.map non of them is organized. Is there a way to make them organized and … -
Django Rest Framework drf-nested-routers example of Infinite-depth Nesting and Hyperlinks for Nested resources
I am quite new to django-rest-framework.

When does Django load the apps?
While messing around with signals I discovered that Django does not load the apps until some point after __init__.py runs. When does Django load the apps?

Does memcache need to be started as a daemon separately when used with django?
I am trying to integrate caching with my django project. After some research I am convinced memcache is best for this. So, I require to install memcache through apt-get memcache and then its python bindings again as another apt-get python-memcache. Then, I need to include in settings.py: CACHES = { 'default':{ 'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache', 'LOCATION': '127.0.0.1;11211', } } My question is, all the tutorials follow upto this step. Is the above enough for setting up the cache? Do I need to do something to start memcache when running the project? If so, can I start memcache with python manage.py runserver command? -
One-To-Many Relationship Django
I am coding up a dictionary using Django. I want a word to have multiple definitions, if necessary. This would be a one-to-many relationship, but Django does not seem to have a OneToManyField.

Also, deleting a word should delete all definitions of that word. Finally, a_definition.word should give me the word associated with that definition. Help? -

Django on IIS: Debugging IIS Error due to FastCGI request timeout on large file upload
I'm trying to host a Django web application on a windows 10 machine with IIS 10 with FastCGI. Whilst everything is running good so far, I'm running into problems with certain POST-requests while uploading larger files (~120MB), namely an HTTP 500 Error. I'm at a point where I don't know how to debug any further. I resolved the Error "413.1 - Request Entity Too Large" by increasing the request limits. However, now I get an HTTP-error stating the following: C:\Apps\Python3\python.exe - The FastCGI process exceeded configured request timeout The timeout is set to 90 seconds, and I can tell that after the uploading of files completes, my browser is waiting about that time for a response from the server. There are not that much operations to perform within the Django-view for responding to the request. If I run the django developement server on the same machine, the response is beeing send justs seconds after the files were uploaded. The duration, the IIS takes to send the HTTP 500 response, takes more than 1 minute longer. I added some code to the Django-view in the post()-method to write something to a file whenever the method is called: def post(self, request, *args, … -

Modified “SM2+” Algorithm for Flashcard App Rating
I don’t know how to modify code for my adaptation of a flashcard app that uses an old algorithm to return flashcard data based on easiness rather than difficulty level, which returns a more precise result. According to the authors, the arguments should be changed as follows. The full calculation is displayed at the link below. I need your help in transforming the code to reflect the new algorithm. The Modified “SM2+” Algorithm http://www.blueraja.com/blog/477/a-better-spaced-repetition-learning-algorithm-sm2 Here is the new algorithm, with all the above improvements in place. For each review-item, store the following data: • difficulty:float – How difficult the item is, from [0.0, 1.0]. Defaults to 0.3 (if the software has no way of determining a better default for an item) • daysBetweenReviews:float – How many days should occur between review attempts for this item • dateLastReviewed:datetime – The last time this item was reviewed When the user wants to review items, choose the top 10~20 items, ordered descending by percentageOverdue (defined below), discarding items reviewed in the past 8 or so hours. After an item is attempted, choose a performanceRating from [0.0, 1.0], with 1.0 being the best. Set a cutoff point for the answer being “correct” (default is … -

Using external API for token based authentication in Django (DRF)
Context My API accepts a jwt-token that I can pass to an external endpoint which will return 401 if invalid/expired or user information if still valid. Based on this I will either return 401 or filtered data belonging to the user. Also, POST request's need to involve writing who this resource belongs to for the GET to work. I tried to do this by overriding the get_queryset and perform_create methods. My viewset looks something like this: class ReportViewSet(AuthorizedUserBasedFilteredViewset): queryset = Report.objects.all() serializer_class = ReportSerializer def perform_create(self, serializer): try: username = self.get_authorized_user()['user']['username'] except Exception as e: return Response({'error': 'Token does not exist'}, status=HTTP_401_UNAUTHORIZED) serializer.save(creatd_by=username) def get_queryset(self): try: username = self.get_authorized_user()['user']['username'] except Exception as e: return Response({'error': 'Token does not exist'}, status=HTTP_401_UNAUTHORIZED) return Report.objects.filter(created_by=username) This doesn't work because get_queryset expects a queryset as response. Questions How do I bubble up the authorize exception in get_queryset? Is there some other method I should be overriding to the authentication entirely? I still need to pass the username recieved to get_queryset for the authentication to be successful Is there a better way to do this? I looked at the RemoteUserAuthenticationBackend but that still involved creation of a User object but for this use case the … -
Python issues with form.cleaned_data.get('username')
When I submit my form, if valid, it should redirect me to my home page but it doesn't due to this line username = form.cleaned_data.get('username'), when I remove it works fine but then again I need that line to get the form data. Here's my code views.py from django.shortcuts import render, redirect from django.contrib import messages from django.contrib.auth.forms import UserCreationForm def register(request): if request.method == 'POST': form = UserCreationForm(request.POST) if form.is_valid(): username = form.cleaned_data.get('username') #Where the problem lies messages.success(request, 'Account created!') return redirect('home-page') else: form = UserCreationForm() return render(request, 'users/register.html', {'form': form}) I honestly can't figure out what's wrong with that line of code. I'm using Django v 3.0.4 btw -
Problem loading images from static in a .js file
scripts.js code: $(document).ready(function(){ $('#user').hover(function() { $('#user img').attr('src', "{% static 'images/user_selected.png' %}"); }, function() { $('#user img').attr('src', "{% static 'images/user.png' %}"); }); }); It works fine when I write it directly in my base.html file, but when I place it in an external .js file it fails to load images. Scripts.js file loads but images do not. base.html code: <head> ... <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script> <script src="{% static 'js/scripts.js' %}"></script> ... </head> <body> ... <a href="{%url 'logout' %}">LOG OUT</a> <a id="user" href="#"><img src="{% static 'images/user.png' %}" height="14px" width="14px" id="user-icon" /><span id="user-name"> {{request.user.username}}</span></a> ... </body> -
Celery beat sends task regularly, but celery only processes them from time to time in production
I have a django project with celery integrated using redis. My celery worker works perfectly in local development, and now I'm deploying in production. Before daemonizing the process I want to see how celery behaves in the server. The thing is, celery beat sends the tasks correctly every minute (as I scheduled) but the worker seems not to receive it every time. Sometimes it requires 4/5 minutes until the task is received and processed. How is that possible? I have tried debugging, but there is very few information. see my setup: settings.py CELERY_TIMEZONE = 'Europe/Warsaw' CELERY_BROKER_URL = 'redis://localhost:6379' CELERY_RESULT_BACKEND = 'redis://localhost:6379' CELERY_ACCEPT_CONTENT = ['application/json'] CELERY_RESULT_SERIALIZER = 'json' CELERY_TASK_SERIALIZER = 'json' # Other Celery settings CELERY_BEAT_SCHEDULE = { 'task-number-one': { 'task': 'predict_assistance.alerts.tasks.check_measures', 'schedule': crontab(minute='*/1'), }, } tasks.py from __future__ import absolute_import, unicode_literals from celery import shared_task @shared_task() def check_measures(): print('doing something') celery.py from __future__ import absolute_import, unicode_literals import os from celery import Celery os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'config.settings.local') app = Celery('predict_assistance') app.config_from_object('django.conf:settings', namespace='CELERY') app.autodiscover_tasks() hereby my logs in production: [2020-03-11 16:09:00,028: INFO/Beat] Scheduler: Sending due task task-number-one (predict_assistance.alerts.tasks.check_measures) [2020-03-11 16:09:00,038: INFO/MainProcess] Received task: predict_assistance.alerts.tasks.check_measures[86f5c999-a53c-44dc-b568-00d924b5da9e] [2020-03-11 16:09:00,046: WARNING/ForkPoolWorker-3] doing something [2020-03-11 16:09:00,047: INFO/ForkPoolWorker-3] predict_assistance.alerts.tasks.check_measures[86f5c999-a53c-44dc-b568-00d924b5da9e]: doing something logger [2020-03-11 16:09:00,204: INFO/ForkPoolWorker-3] Task predict_assistance.alerts.tasks.check_measures[86f5c999-a53c-44dc-b568-00d924b5da9e] succeeded in 0.16194193065166473s: …
