Django redis caching per url
So I am trying to implement moreover learn how to cache Django views per URL. I am able to do so and here is what is happening... I visit a URL for 1st time and Django sets the caches. I get my result from cache and not from querying the database during the second visit if the browser is same. Now the doubt is - if I change my browser from the first visit and second visit, for example, do the first visit from Chrome (it sets the cache) and during the second visit from Mozilla, it again sets the cache. I was expecting it to return the result from the cache. During my research on StackOverflow and checking what it sets as cache, I found there are two important things first being a header and the second being the content. And I think every time a browser is changed the header is new so it sets the cache instead of returning the result from cache. Do let me know if I am wrong. I have a public URL and I was thinking to show data from the cache if a subsequent request is made, irrespective of browser or mobile/laptop/desktop, … -

How can I add a field to a many-to-many relationship in Django?
This is a question about how to add a field to a many-to-many relationship in Django. I have a model LandingPage and a model Product. (Code below). In my project, LandingPages can have many Products listed on them and those same Products can appear on multiple different LandingPages. Product is connected to LandingPage via a ManyToManyField. My Goal: I am trying to figure out how to add a field so that I can set the order (1 through 10) for Products on their associated LandingPages. Reminder, Product instances can appear on multiple LandingPages, so each instance will need to have a different order attribute. Ideally, I'd like to expose this functionality via the built-in Django admin. Right now it shows the relationships table, but not the order field as it does not yet exist. (Screenshots/mockups below). My Code: models.py class LandingPage(models.Model): """Stores a single LandingPage and metadata. """ name = models.CharField(max_length=200, help_text="The name is only used internally. It is not visible to the public.") slug = models.SlugField(default="", editable=False, max_length=150, null=False, verbose_name="Slug", help_text="This is not editable.") # Additional fields that I do not believe are relevant class Product(models.Model): """Stores a single Product and metadata. """ name = models.CharField(max_length=200, help_text="Used internally. Not … -
django.forms.fields.DateTimeField got error: 'list' object has no attribute 'strip', when calling BaseForm._clean_fields()
Handling of a POST request led to calling _clean_fields(self). The form contains a field in type of django.forms.fields.DateTimeField, and it triggered an exception of "AttributeError" saying 'list' object has no attribute 'strip'. It looks like, on step value = field.widget.value_from_datadict(self.data, self.files, self.add_prefix(name)) the field got a return as ['', ''], which is a list of empty strings. Later on, step value = field.clean(value) triggered the exception. I'm still new to Django, and this is a project to upgrade from Python2.7+Django1.8 to Python3.7+Django3.1. The older version doesn't have this issue. Any pointers will be highly appreciated. Partial source code of django/forms/forms.py: def _clean_fields(self): for name, field in self.fields.items(): # value_from_datadict() gets the data from the data dictionaries. # Each widget type knows how to retrieve its own data, because some # widgets split data over several HTML fields. if field.disabled: value = self.get_initial_for_field(field, name) else: value = field.widget.value_from_datadict(self.data, self.files, self.add_prefix(name)) try: if isinstance(field, FileField): initial = self.get_initial_for_field(field, name) value = field.clean(value, initial) else: value = field.clean(value) self.cleaned_data[name] = value if hasattr(self, 'clean_%s' % name): value = getattr(self, 'clean_%s' % name)() self.cleaned_data[name] = value except ValidationError as e: self.add_error(name, e) -

POST and GET requests to a client API URL using Django REST
I am kind of new to API. I am working on a project where I can send POST and GET requests to different APIs. I just want to know how sort of the class in the view file should look like. For example, I have a class that inherits generics.GenericAPIView. How do I send a get request to a specific URL or how do I save the data using the serializer to the database with post request? class ArticelViewSet(generics.GenericAPIView, mixins.ListModelMixin, mixins.CreateModelMixin): serializer_class = ArticleSerializer_Modelserializers queryset = Article.objects.all() lookup_field = 'id' def get(self, request, id=None): if id: return self.retrieve(request) else: return self.list(request) def post(self, request): return self.create(request) #return the created object -
How to serialize three models with many to many relationships in Django Rest Framework

Static files django do not load with nginx and daphne
recently I needed to implement a solution with django-channels in an application that was in production with NGINX and uWSGI. It worked well. So, I had to stop the systemd service that managed uwsgi in order to run and manage Daphne as follows: [Unit] Description=daphne daemon for ubuntu After=network.target [Service] User=ubuntu Group=ubuntu WorkingDirectory=/path/to/my/app/ ExecStart=/path/to/my/app/env/bin/daphne -b 0.0.0.0 -p 8000 myproject.asgi:application [Install] WantedBy=multi-user.target However, when performing modifications to the nginx file, even though the application is running, static files are not being loaded.

No module named 'mysite.settings'
I know this question has been asked quite a lot but all the solutions given do not seem to fit for me. I run this in a venv with python 3.6.8 and django 2.2.10 When I run django from cli it works and all functionality is working great so I know it is not django itself that is failing me. Path to wsgi script is "/opt/sites/aws/okta/wsgi.py" Actual wsgi.py: import os, sys sys.path.append('/opt/sites/aws') #path = os.path.dirname(os.path.dirname(os.path.abspath(file))) #sys.path.append(path) print(sys.path) os.environ.setdefault("DJANGO_SETTINGS_MODULE", "okta.settings") from django.core.wsgi import get_wsgi_application application = get_wsgi_application() When running python to see what errors it gives I get ModuleNotFoundError: No module named 'okta.settings' I get the same error when running apache with debug logging. I have quadruple checked the path and the environment variables and they are set right in the wsgi.py script. Please help! Thank You, -Chris -

Trouble implementing Voting to a Django File Upload project
I'm new to programming and have been following along Vitor Freitas' Django File Upload Project. I was able to complete the project, but now I want to add a vote function to the project that takes one of three choices ['Aye', 'Nay', 'Abstain'] on the uploaded file. I'm just not sure if what I want is possible. After uploading the file using forms.py from django import forms from .models import Leg class LegForm(forms.ModelForm): class Meta: model = Leg fields = ('title', 'ministry', 'pdf', 'cast','votes') widgets = { 'cast': forms.HiddenInput(), 'votes': forms.HiddenInput() }# Hide cast and vote totals options when uploading file for review In views I can call the form and list it Views.py class LegListView(ListView): model = Leg template_name = 'class_leg_list.html' context_object_name = 'legs' class UploadLegView(CreateView): model = Leg fields = ('id','title', 'ministry', 'pdf',) #leave out (cast and votes )fields to hide in upload form success_url = reverse_lazy('class_leg_list') template_name = 'upload_leg.html' Html file: {% extends 'base.html' %} {% block content %} {% block content_header %} <h2>Legislation</h2> {% endblock %} <table class="table mb-0"> <thead> <tr> <th>ID</th> <th>Title</th> <th>Ministry</th> <th>View</th> <th>Cast Vote</th> <!-- <th>Votes</th>--> </tr> </thead> <tbody> {% for leg in legs %} <tr> <td>{{ leg.id }}</td> <td>{{ leg.title }}</td> <td>{{ … -
Is there a way to set an expiration time for a Django cache lock?
I have a Django 3.1.3 server that uses Redis for its cache via django-redis 4.12.1. I know that cache locks can generally be set via the following: with cache.lock('my_cache_lock_key'): # Execute some logic here, such as: cache.set('some_key', 'Hello world', 3000) Generally, the cache lock releases when the with block completes execution. However, I have some custom logic in my code that sometimes does not release the cache lock (which is fine for my own reasons). My question: is there a way to set a timeout value for Django cache locks, much in the same way as you can set timeouts for setting cache values (cache.set('some_key', 'Hello world', 3000))? -
Django field with multiple model option
I have a scenario where I have a model "Thread". There are two fields in it. "Sender" and "receiver". Also there are other models like "Teacher", "Student", "Principal" etc. Now in the "Thread" model, the sender can be a "Student", and receiver can be a "Teacher" OR Vice Versa. What is the solution for that: class Thread(models.Model): sender = models.(???) # can't be a student relation because a sender can be a teacher too receiver = models.(???) # same here. Is there any way that I can dynamically first select the model and then pick an object of that list. I have seen this functionality in Odoo. But is there anything in Django? -
Why list index in Django Template it's not in the output?
I use this in the template {% for num in '0123456789'|make_list %} <li>{{ respuesta.num }}: {{ puntaje.num }} </li> But then, the page only shows something like this : : (and the rest goes on like that) Why it doesn't show the elements from the lists? If I only use {{num}} it prints the actual nums from the for iteration and if I use {{respuesta}} it shows the hole list. This happens without triggering any error message or anything else (and yes, there are elements in the list "respuesta" and "puntaje"). -
(Django App) Django-Microsoft-Auth - Please enter the correct username and password
I have been trying to set up this app, but I am a stuck on step 10 in the usage documentation: Start site and go to /admin and logout if you are logged in. Login as Microsoft/Office 365/Xbox Live user. It will fail. This will automatically create your new user. Login as a Password user with access to change user accounts.

I created a user with that program (Only username and password, no email), but the /admin page says the following when I attempt to log in with these credentials: "Please enter the correct username and password for a staff account.

How to know which group a user belongs to
I am developing an application that allows me to control the users that belong to a certain group, but I find a problem that I don't know how to do correctly, I currently have two groups that are day and night, but I have a problem, and that is that those groups They are validated to know which one they belong to and thus show only information from that group, but if I wanted to add more groups than I have, is there a way to know which group a user belongs to and so on to be able to validate the information that I show in templates, this is my model: class User(AbstractUser): def get_full_name(self): return f'{self.first_name} {self.last_name}' @receiver(post_save, sender=User) def group_user(sender, instance, *args, **kwargs): if instance.groups: if instance.groups == 'diurno': group = Group.objects.get(name='diurno') instance.groups.clear() instance.groups.add(group) else: group = Group.objects.get(name='nocturno') instance.groups.clear() instance.groups.add(group) This is my view: class CarListView(LoginRequiredMixin, ListView): login_url = 'users:login' template_name = 'index.html' paginate_by = 6 def get_queryset(self): group = self.request.user.groups.filter( name='diurno').exists() if group: return Car.objects.annotate(Count('partner')).order_by('-pk') else: user = User.objects.filter(pk=self.request.user.pk).first() return Car.objects.filter(user=user) -
Pycharm CE not hitting breakpoints in my Django project

I am creating a project following the YouTube tutorial at this link: https://youtu.be/JD-age0BPVo?t=133 I recently did the 6th and 7th video, but accidentally, I started from the 7th and got back to the 6th video. I am currently getting the Forbidden errors when I try to click Create Room button: Forbidden: /api/create-room [23/Dec/2020 13:46:38] "POST /api/create-room HTTP/1.1" 403 58 Interestingly, I have no required login/permission/test. I can't understand what is forbidden. I read other Django 403 Error questions and they usually have authorization steps that gives that error but I don't have it. Since the first line of error has POST in it, I am copying my only pieces of code including POST in them. CreateRoomPage.js: handleRoomButtonPressed() { const requestOptions = { method: "POST", headers: { "Content-Type": "application/json" }, body: JSON.stringify({ votes_to_skip: this.state.votesToSkip, guest_can_pause: this.state.guestCanPause, }), }; fetch("/api/create-room", requestOptions) .then((response) => response.json()) .then((data) => this.props.history.push("/room/" + data.code)); } views.py: class CreateRoomView(APIView): serializer_class = CreateRoomSerializer def post(self, request, format=None): if not self.request.session.exists(self.request.session.session_key): self.request.session.create() serializer = self.serializer_class(data=request.data) if serializer.is_valid(): guest_can_pause = serializer.data.get('guest_can_pause') votes_to_skip = serializer.data.get('votes_to_skip') host = self.request.session.session_key queryset = Room.objects.filter(host=host) if queryset.exists(): room = queryset[0] room.guest_can_pause = guest_can_pause room.votes_to_skip = votes_to_skip room.save(update_fields=['guest_can_pause', 'votes_to_skip']) return Response(RoomSerializer(room).data, status=status.HTTP_200_OK) else: room = Room(host=host, guest_can_pause=guest_can_pause, … -
Django template custom filter does not change size of button
I have a Django template variable and custom filter inside a button stylized with bootstrap 4. <button type="submit" class="btn btn-outline-dark text-left mb-2" disabled> {{ my_variable | my_filter}} </button> If my_filterincreases the length of my_variable, I find that the size of the button is not automatically extended as I assume that its size is processed by Django before the filter is applied. Is there a way around this?
