Django - Changing the url to redirect from a middleware on the fly
I'm building a SSO login meant to be used from links send by emails. Each link should auto-connect the user (SSO), and be clickable multiple times (they have a TTL, which depends on the email) It works fine, but I'm concerned about the end-user sharing his url on social networks (basically copy/pasting the url, which contains the SSO token), allowing anyone following the link to be logged in automatically. My first attempt was to try to remove the GET SSO_TOKEN parameter, from my SSOMiddleware, as follow: if remove_token_middleware: request.GET._mutable = True # GET is not mutable by default, we force it # Remove the token from the url to avoid displaying it to the client (avoids sharing sso token when copy/pasting url) del request.GET[SSO_TOKEN_PARAM] request.GET._mutable = False # Restore default mutability return login(request, user) if service.get("auto_auth") else None Basically, my thought was that since the SSO_TOKEN is in the request.get object, removing it from it would eventually change the url where the user gets redirected In my controller, here is how the user gets "redirected" (using render) return render(request, 'campagne_emprunt/liste_offres_prets.html', locals()) When using render, there is no redirection, and the SSO token is still visible in the URL (in the … -

Vote Model Operations causing unknown troubles
I made a Vote model given below. My blog model has two operations that upvotes or downvotes the specific blog. For example, When a single user upvotes, the votes field in Blog increases and a UserVote Model has a record of it and when the same user downvotes, it changes it's vote_type and updates the record. The problem comes in when a second user casts a vote. After an upvote, when the second user downvotes, it says that he has already voted (although it should've changed his vote_type to downvote) I've been going through this problem and I can't find a solution of it anywhere. class Blog(models.Model): title = models.CharField(max_length=100, blank=True, default='') description = models.TextField(max_length=1500) created = models.DateTimeField(auto_now_add=True) owner = models.ForeignKey('auth.User', related_name='blog', on_delete=models.CASCADE, null=True) image = models.FileField(blank=True, null=True) votes = models.IntegerField(default=0) def upvote(self, user): try: if UserVote.objects.filter(user=user, blog=self, vote_type='down').exists(): self.post_votes.update(user=user, blog=self, vote_type='up') self.votes += 2 else: self.post_votes.create(user=user, blog=self, vote_type='up') self.votes += 1 self.save() except IntegrityError: return 'already_voted' return 'ok' def downvote(self, user): try: if UserVote.objects.filter(user=user, blog=self, vote_type='up').exists(): self.post_votes.update(user=user, blog=self, vote_type='down') self.votes -= 2 else: self.post_votes.create(user=user, blog=self, vote_type='down') self.votes -= 1 self.save() except IntegrityError: return 'already_voted' return 'ok' class UserVote(models.Model): user = models.ForeignKey('auth.User', related_name='user_votes', on_delete=models.CASCADE) blog = models.ForeignKey(Blog, related_name='post_votes', on_delete=models.CASCADE) vote_type … -
Form filter - Unsupported lookup 'gte' for FloatField

Why static files not loaded when im using slug in url?
When im using slug in my url, the .html files wont load the static files.

Explanation needed with Django and AMP logic using 1 url
I'm using AMP at one of my parts of the website with Django template and python, my question is what will happen to a page (*SEO wise) if I take and break an AMPed page (only on desktop) and leave the page AMPed on mobile?! To be more specific, I have made a full AMP page for both mobile and desktop which use the url (/example-amp-url) and now I need to add a widget to the page which is rendered with js and not AMPed at all but render it only on desktop. Any one knows how it would impact on my SEO? Because for now in my site-map this page is AMPed both on mobile search and on desktop page (if Im losing the AMP on desktop it is fine but if I lose both its a huge problem thats why Im afraid to test it) -
DetailedView and expiring items not working in Django
I'm working on a simple application, where elements should expire automatically after 5 minutes. In models.py I have the following: from django.utils import timezone def calc_default_expire(): return timezone.now() + timezone.timedelta(minutes=5) class MyModel(models.Model): uploaded_at = models.DateTimeField(auto_now_add=True) expire_date = models.DateTimeField(default=calc_default_expire) ... In my views.py, I have the following: from django.views.generic import DetailView from .models import MyModel from django.utils import timezone class MyModelDetail(DetailView): model = MyModel queryset = AppFile.objects.filter(expire_date__gt=timezone.now()) I'm getting some strange behaviour. Even after 5 minutes, when I call the url of the expired item, it still gets returned (http code 200). However, when I restart the builtin django dev server, and call the url again, I'm getting a 404, which is the desired result. I see two possible causes: the built-in webserver is caching some stuff (I doubt this to be honest, I could not find anything in the docs that mentions this behaviour) I'm doing something wrong in my queryset filter (but I'm not seeing it). Expire_date seems to be calculated correctly when I add new items. Anyone got a clue what I'm missing here? USE_TZ = True in my settings.py BTW. -
CORS problems in Vue Axios frontend and Django Rest API backend
Repository with the project I am getting information about blocked access by CORS policy and none of the solutions I looked at seemed to be working. Access to XMLHttpRequest at 'http://localhost:8000/search' from origin 'http://localhost:8080' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. My server is hosted locally on localhost:8000 and frontend is on loacalhost:8080.

I followed those instructions but the response is still the same. The view responsible for the response is here and settings were set up here I do not want to: Disable web security in Chrome Use JSONP Use a third party site to re-route my requests If anyone would like to run the project just install requirements.txt from main folder and follow README from main and frontend folders. -
How to add(sync) separate django user in LDAP groups?
Env: python - 3.6.6 django - 2.x.x django-auth-ldap - 2.0.0 python-ldap - 3.2.0 Explanation: E.g. there is a user in django DB, which was synced from LDAP by following code (taken from this answer): from django_auth_ldap.backend import LDAPBackend # in settings.py AUTH_LDAP_MIRROR_GROUPS is enabled ldap_backend = LDAPBackend() ldap_backend.populate_user('username') User is created in django DB and groups are similar as in LDAP. After that this user was added(or removed) into group: user.groups.add(some_group) # this group exists in LDAP too # or for example remove user from group Question: How to sync this ralation between User and Group from django to LDAP?

Django: open PDF file object
in my Django app I´m trying to open and show pdf files that wasn´t loaded to a model, but can´t find the appropiate way. I have a group of PDF invoices that I manualy copied to media/my_folder (I use Dropbox as media host to be able to do that). Then I want to show each invoice when requested. After investigating several posts, I think the way to do it is creating a file object dinamycaly. invoice_path = "my_folder/" + invoice_number + ".pdf" f = open(invoice_path, 'w') myfile = File(f) Then I understand the in the template I could be able to access the file as it was loaded to the model. <p><a href="{{ myfile.url }}" target="_blank">Ver factura AFIP</a></p>7 I get a FileNotFoundError, I guess I´m not setting the path to media files correctly. Any clues? Thanks! -

Make sure that this property is reactive, either in the data option, or for class-based components, by initializing the property. Also I get next response {readyState: 4, getResponseHeader: ƒ, getAllResponseHeaders: ƒ, setRequestHeader: ƒ, overrideMimeType: ƒ, …} abort: ƒ ( statusText ) always: ƒ () catch: … -
Form receives old data from model
I have form which should receive it initial value from the latest entry stored in models. However if I edit or delete model data through admin panel, initial data displayed in the form remains the same old one (despite the fact that it is deleted in models). I am baffled what I am doing wrong. At first I thought that its Chrome who saves old data, but it remains the same after resting it with ctr+shift+r. My forms.py: from stv.models import BazineKaina, class DrgSkaiciuokle(forms.Form): bazine_kaina = forms.DecimalField(max_digits=5, decimal_places=2, required=True, label="Įveskite bazinę kainą:", initial= BazineKaina.objects.latest('data'), ) def clean_bazine_kaina(self): bazine_kaina = self.cleaned_data['bazine_kaina'] return bazine_kaina My models.py: class BazineKaina(models.Model): bazka = models.DecimalField(max_digits=5, decimal_places=2) data = models.DateField(auto_now=False, auto_now_add=True) def __str__(self): return str(self.bazka) class Meta: verbose_name_plural = "Bazinė kaina" get_latest_by = 'data' Please help me to find out why old data is still received by form? EDIT: I found out, that if I restart the server data will be refreshed, but that cant be solution in production. How to make form get new data every time its called?
