How to store and serve static images using Django, Pythonanywhere, CDN and cloud storage
I'm quite new to web development, just a self-taught enthusiast, so be kind :) Right now I'm trying to deploy my website (built with Django) on Pythonanywhere. Following all advice on static files and it actually works. So basics are done. But images load painfully slow. I know there is some size and weight optimisation to do, but I also heard that the best way to serve large amount of images is to store them separately from the code (in Amazon S3, Google Cloud Storage) and serve through CDN. I have also found a nice service called IMGIX to always serve the most appropriate version of an image. Now the hard question: how does it work together? OK, I can upload all images to the bucket, point CDN to it too. But then how do I go about 'collectstatic' in Django? How do I keep those images linked to the models? Do I resolve it by pointing STATIC_DIR and STATIC_ROOT to that bucket? My mind is failing me here and googling did not help either. Any help would be highly appreciated. -

Cannot override templates found in admin/auth and admin/widgets in Django
Context I want to override the following django templates: django/contrib/admin/templates/admin/widgets/clearable_file_input.html django/contrib/admin/templates/admin/auth/user/change_password.html With these custom templates: <project_root>/templates/admin/widgets/clearable_file_input.html <project_root>/templates/admin/auth/user/change_password.html My TEMPLATES settings are configured as followed: TEMPLATES = [ { "BACKEND": "django.template.backends.django.DjangoTemplates", "DIRS": [os.path.join(BASE_DIR, "templates")], "APP_DIRS": True, "OPTIONS": { "context_processors": [ "django.template.context_processors.debug", "django.template.context_processors.request", "django.contrib.auth.context_processors.auth", "django.contrib.messages.context_processors.messages", ], }, }, ] Problem While I have managed to successfully override a lot of other templates that exist in the django/contrib/admin/templates/admin/ path, I cannot seem to be able to override templates that exist in the paths mentioned above.

Is it possible to use celery with kubernetes and how can i install kubernetes-celery django setup? -
Django Generate Random String Internally and Validate in Form POST Request
Let's say I have a form and want to add some extra security to it. <form method="POST" enctype="multipart/form-data"> ... <button name="delete" role="button">Delete</button> <button name="save" role="button" type="submit">Save</button> </form> I use class-based views. I add a random string to the context within get_context_data(): import random, string def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) context['random_string'] = ''.join(random.choices(string.ascii_letters + string.digits, k=20)) return context My form then is: <form method="POST" enctype="multipart/form-data"> ... <button name="delete" value="{{ random_string }}" role="button">Delete</button> <button name="save" role="button" type="submit">Save</button> </form> So what I want to do is: Generate a unique string internally and pass to template using context variable named random_string. When form is submitted, if request.POST has a 'delete' key, I want to validate that the value was generated internally from my system. request.POST would look something like this: <QueryDict: { 'csrfmiddlewaretoken': ['gqYBmmeba8Y...EQFVbzpXyPU0TXF'], 'user': ['19'], ... 'delete': ['h3teSs4bLizQF69EvtAU'] }> I'm hoping someone experienced can tell me either: I'm going about this all wrong, here's how to do it, or here's what I should do instead, or there's no need because xyz. My overall goal is just a sanity check to know that the generated random string was actually generated from my system and the user isn't trying to delete something in some … -
What's the problem with sharing job stores in APScheduler?
I did quite get the problem that arises by sharing a job store across multiple schedulers in APScheduler. The official documentation mentions Job stores must never be shared between schedulers but doesn't discuss the problems related to that, Can someone please explain it? and also if I deploy a Django application containing APScheduler in production, will multiple job stores be created for each worker process? -

How to programmatically set the model when using Django CreateView?
I am trying to programmatically set the model for a Django class-based view that inherits from CreateView and displays a form for creating a 'member' object. My problem is that my template is not displaying the form itself. Note that I override the 'get' method to determine what model the view should use. The template page renders and I see the submit button but when I view the page's source code, the form is missing. Here's my code: # urls.py path('profile/create/', views.ProfileCreate.as_view(), name='profile-create'), # views.py class ProfileCreate(CreateView): model = None template_name = None def get(self, request, *args, **kwargs): member = Member.objects.get(user=request.user) if member.is_couple: self.model = ProfileCouple self.template_name = 'account/profile_couple_create.html' self.fields = ['person1_name', 'person2_name', 'person1_dob', 'person2_dob'] else: self.model = ProfileSingle self.template_name = 'account/profile_single_create.html' self.fields = ['person1_name', 'person1_dob'] context = {} return render(request, self.template_name, context) # models.py class ProfileSingle(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE, null=True) person1_name = models.CharField(_("Name"), max_length=50) person1_dob = models.DateField() def __str__(self): return self.user.username class ProfileCouple(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE, null=True) person1_name = models.CharField(_("Name 1"), max_length=50) person1_dob = models.DateField() person2_name = models.CharField(_("Name 2"), max_length=50) person2_dob = models.DateField() def __str__(self): return self.user.username # forms.py class CreateSingleProfileForm(forms.ModelForm): class Meta: model = ProfileSingle fields = ('user', 'person1_name', 'person1_dob') labels = {'user': _('Username'), 'person1_name': _( … -
How to connect local React app to local REST API for production

Uploading duplicated files with Django when reloading page
I'm trying to upload some files and I'm having problems with duplication. To uploading the file I do the following: views.py: from django.core.files.storage import FileSystemStorage def contView(request): if request.method == 'POST' and request.FILES.get('myfile'): myfile = request.FILES['myfile'] fs = FileSystemStorage() filename = fs.save('uploads/'+myfile.name, myfile) uploaded_file_url = fs.url(filename) # Return template_name ='cont/mainCont.html' context = {} return render(request, template_name, context) Template: <form method="post" enctype="multipart/form-data">{% csrf_token %} <div class="input-group"> <input type="file" name="myfile" class="form-control"> <span class="input-group-btn"> <button class="btn btn-default" type="submit">Importar</button> </span> </div> </form> The upload works perfectly but when I refresh the page it upload the same file again.

Use Twitter API in Celery task - need to use access_key and access_secret from auth user
I have the following function in my views.py that will send me the authorised user's key tokens. I can then manually amend these tokens for my Twitter API function locally to run the program. def like(request): oauth = tweepy.OAuthHandler(CONSUMER_KEY, CONSUMER_SECRET) access_key = request.session['access_key_tw'] access_secret = request.session['access_secret_tw'] send_mail( 'Auth Codes', # subject 'access key - ' + os.environ['oaccess_key'] + '\n' + 'access_secret - ' + os.environ['oaccess_secret'], # message DEFAULT_FROM_EMAIL, # from email [DEFAULT_FROM_EMAIL], ) return render(request, "home.html") However having to do this manually isn't great and for security reasons I'd rather not have them emailed. I want to push the function to a celery task so that I don't need the sendmail() at all. My celery task would look like this after liking.delay() being called within like() - @app.task(bind=True) def liking(self): oauth = tweepy.OAuthHandler(CONSUMER_KEY, CONSUMER_SECRET) oauth.set_access_token(access_key, access_secret) api = tweepy.API(oauth) ** Rest of my code using the Twitter API ** I have tried setting the access_key and access_secret as environmental variables but they do not import to the celery.py. Is there any way that I'm missing that can enable this to work? -

docker React, django(gunicorn), nginx reverse proxy with https give Bad request 400 on accessing backend APIs
I have containerized application with following containers working together with docker-compose Nginx - reverse proxy React - frontend Django served using gunicorn - backend When using http all works well with frontend and backend. I used letsencrypt certbot to generate ssl certificates. On switching to https, fronend seems to work fine however none of backend apis are working. Any request to backend such as login generates 'Bad Request 400' response. I have tried following options but none worked. a. Switching Django to production and adding ALLOWED_HOSTS=['*'] or specific domain b. Adding upstream in nginx.conf c. disableHostCheck: true in webpack devServer. Following are my docker-compose and nginx.conf respectively docker-compose.yml services: reverse_proxy: image: nginx:1.17.10 volumes: - ./reverse_proxy/nginx.conf:/etc/nginx/nginx.conf - ./reverse_proxy/certbot-etc:/etc/letsencrypt - ./reverse_proxy/certbot-var:/var/lib/letsencrypt ports: - 80:80 - 443:443 depends_on: - webapp - frontend webapp: build : ./backend/ command: gunicorn --bind 0.0.0.0:8000 ai.wsgi:application expose: - 8000 volumes: - ./backend/:/app ports: - 8000:8000 frontend: build: ./frontend/ai-web/ command: npm run ai ports: - 3000:3000 nginx.conf worker_processes auto; pid /run/nginx.pid; include /etc/nginx/modules-enabled/*.conf; events { worker_connections 1024; } http { fastcgi_read_timeout 3000; proxy_read_timeout 3000; client_max_body_size 1000M; upstream django { server webapp:8000; } server { listen 80; server_name localhost 127.0.0.1; location / { proxy_pass http://frontend:3000; proxy_set_header Host $host; proxy_set_header X-Forwarded-For … -
Replace views functions for view class in Django
I would like to replace my views functions for a class. I'm new in Django and I try to send service object from user function to metrics function but I can´t do that with < a href="{% url 'metrics' %}">Metrics</a> in home.html. I don't know how to call a class instead a function too my code: def user(request): username = request.POST.get('username') password = request.POST.get('password') service = Service() service.start(username=username, password=password) return render( request, 'home.html', { 'service': service, } ) def metrics(request, service): metrics = service.get_metrics() return render(request, 'metrics.html', { 'metrics', metrics } the code I would like or something like it: class User(object): def __init__( self ): super(User, self).__init__() self.usernme = '' self.password = '' self.service = '' def get_service(self, request): self.username = request.POST.get('username') self.password = request.POST.get('password') self.service = Service() self.service.start(username=self.username, password=self.password) return render( request, 'home.html', {} ) def metrics(self, request): metrics = self.service.get_metrics() return render( request, 'metrics.html', { 'metrics': metrics, } )
