HTML not rendering properly
I'm trying to render an HTML in my django project on the basis of data that I'm receiving from the backend but can't understand on how to do it. If somebody can help me out that would be super awesome.

Can I serve static files (css, html, etc.) from a different server in Django
So I'm trying to serve templates, images, css and other static files from a Web Server (frontend) running Apache into an App Server (backend) running Django, the Django app is already proven to work locally so I splited static files and push them into the Web server and the .py files into the App Server, so far I've seen that I need to use mod_wsgi package from Apache and then run $ python manage.py collectstatic So it makes a copy of those static files into the App Server. But the problem comes when changing the urls of every template. Also I saw this other solution but I'm not sure if I implement that solution I still need to do the mod_wsgi thing. Can someone please help me out here please? Or give me some advice on how to do it? Thanks -

Django Post Deployment Issues - Scripts and Models
Hi it's my first time deploying a Django app. I'm using PythonAnywhere to host and learn more. I am aware that deployment requires additional steps and code changes versus dev and believe I have taken these steps researching the documentation and other issues on Stack Overflow. After separating out javascript from the html, migrating the models and collecting the static files I'm having a major issue with the style of the index file not inheriting the base layout as well as being running the javascript. Additionally drop downfields that are reading from models are not working. Note all other pages are inheriting the base file but are not linking to models either for dropdowns. I've reviewed the models and they are in place and populated. Likely I am missing something with the base layout file and the models. Greatly appreciate if someone can point me in the right direction. Layout.html (base layout file) <!DOCTYPE html> <html> <head> <meta charset="utf-8" /> <meta name="viewport" content="width=device-width, initial-scale=1.0"> {% load static %} <link rel="stylesheet" type="text/css" href="{% static 'app/content/bootstrap.min.css' %}" /> <link rel="stylesheet" type="text/css" href="{% static 'app/content/site.css' %}" /> <script src="{% static 'app/scripts/modernizr-2.6.2.js' %}"></script> <script src="https://code.jquery.com/jquery-1.12.4.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script> <link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/select2/4.0.13/css/select2.min.css" integrity="sha512-nMNlpuaDPrqlEls3IX/Q56H36qvBASwb3ipuo3MxeWbsQB1881ox0cRv7UPTgBlriqoynt35KjEwgGUeUXIPnw==" crossorigin="anonymous" /> </head> … -
Restricting Signal Notifications in a Django Project to specific Attribute in Model
I have added a notification everytime a user submits a Like button to a post, the owner of the liked post receives a notification. I have set Value options for each Like button to be Like or Unlike so now I am trying to restrict the notification to be sent only if the Value of the like clicked is Like only. So, now in the Like Model I have added signal and a condition that if the Like.value== Like the signal activates but for some reason it is not working and I am not sure why. My question is: How do I set the notification signal to be sent only when the Like.value== Like? Here is the post models.py: class Post(models.Model): title = models.CharField(max_length=100, unique=True) likes = models.ManyToManyField(User, related_name='liked', blank=True) Here is the like models.py: LIKE_CHOICES = ( ('Like', 'Like'), ('Unlike', 'Unlike') ) class Like(models.Model): # To know Who liked user = models.ForeignKey(User, on_delete=models.CASCADE) post = models.ForeignKey(Post, on_delete=models.CASCADE) value = models.CharField(choices=LIKE_CHOICES, default='Like', max_length=8) updated = models.DateTimeField(auto_now=True) created = models.DateTimeField(auto_now=True) def __str__(self): return f"{self.post}-{self.user}-{self.value}" def user_liked_post(sender, instance, *args, **kwargs): if Like.value=='Like': like = instance post = like.post sender = like.user notify = Notification(post=post, sender=sender, user=post.author, notification_type=1) notify.save() else: None def user_unlike_post(sender, … -
how to set a timer or schedule non-periodical task in Django > 3.0 and DRF
Im new to async programming and new Django's docs aren't really specific what should and should not be done so here is my question. How to set some kind of a timer in Django (or django-programatically in server) after which some Django code will be run. To visualize this I will present an example: Student has 10 minutes to write a test. Student starts a test (enters some view). Student can post his test results within those 10 minutes but if he crosses the 10 minute barrier, the test should stop and such event should be saved in database. This sounds like an async job but I don't know the good practise for coding that. If it can be done synchornousily it would be much better. To clarify - I'm using Django REST framework and the student is on a mobile client. (setting a timer in mobile app is not an option due to security reasons). I know about Celery but it seems like an overkill when Django already has async. I will add that there will be several tousand student tests running at the same time so performance is important. Can anyone help me or point me to a … -

Django values_list returns only one result
i'm just stucked into a problem while returning values from table, here you can look at my Django Model: class Server(models.Model): organization = CustomCharField( choices=get_choices('organizations'), max_length=255, blank=True ) Here you can see my Choice model: class Choice(models.Model): organizations = JSONField(default=list) def __str__(self): return self._meta.model.__name__ So if i try this: Choice.objects.values_list('organizations', flat=True).distinct() I got that: <QuerySet [[['Company1', 'Company1'], ['Company2', 'Company2'], ['Company3', 'Company3'], ['Company4', 'Company4']]]> The main problem contains in this line of code: Server.objects.values_list('organization', flat=True).distinct() And it returns this: <QuerySet ['Company3', '']> What's wrong with this?

Shared Django field across model instances
I'm new to Django, and need help with something quite basic. Suppose we created a model representing a worker, and we wanted to create a function to calculate how much each worker made after taxes. For simplicity, a worker has a take-home pay of their gross income times their tax rate, and the tax rate is a variable that all workers share. class Worker(models.Model): gross_income = models.FloatField(null=True, blank=True) def take_home_pay(self): return self.gross_income * tax_rate I know how to store each worker's gross income in the database. I did it using models.FloatField. Here's my questoin: how would I store the tax rate, which is shared across workers, in the database? -

I already did create 4 objects in Role table which refers to the role of users in website. the Role was a list but I created it in User model as a checkbox input to allow the user to choose what he wants among roles but I can't save my data that comes through cleaned_data which refers to roles data, I get the following error: 'RegisterForm' object has no attribute 'roles' in forms.py file what I miss here? here is my code: forms.py from django import forms from django.contrib.auth.forms import UserCreationForm from .models import User, Profile, Role class RegisterForm(UserCreationForm): password1 = forms.CharField(min_length=4, widget=forms.PasswordInput(attrs={ 'placeholder': 'Password' }), label='password') password2 = forms.CharField(min_length=4, widget=forms.PasswordInput(attrs={ 'placeholder': 'Confirm Password' }), label='Confirm Password') class Meta: model = User fields = ['email', 'first_name', 'last_name', 'roles', 'password1'] widgets = { 'roles': forms.CheckboxSelectMultiple() } def clean_password2(self): password = self.cleaned_data['password1'] password2 = self.cleaned_data['password2'] if password and password2 and password != password2: raise forms.ValidationError("password and confirm password is not same") if len(password) < 4: raise forms.ValidationError('Password is very weak please enter 4 words at least') return password def save(self, commit=True): user = super().save(commit=False) if commit: user.staff = True user.set_password(self.cleaned_data['password1']) self.roles.add(self.cleaned_data['roles']) user.save() return user models.py from django.db import models from django.contrib.auth.models import … -
getting unexpected/unwanted url path when clicking on an href link in django
so, here are all the urls i defined: path("", views.index, name="index"), path("login", views.login_view, name="login"), path("logout", views.logout_view, name="logout"), path("register", views.register, name="register"), path("new", views.new.as_view(), name="new"), path("<int:user>/watchlist", views.watchlist, name="watchlist"), path("<int:user>/<str:name>", views.name, name="name"), path("<str:user>/<str:name>/watchlist/remove", views.remove, name="remove-from-watchlist"), path("<int:user>/<str:name>/watchlist/add", views.add, name="add-to-watchlist"), path("<str:user>/<str:name>/bid", views.bid, name="bid"), path("<str:user>/<str:name>/close", views.close, name="close-bid"), path("<str:user>/<str:name>/comment", views.comment, name="comment"), path("add-category", views.addC, name="add-Category"), path("categories", views.categories, name="categories"), path("<str:cat>/category", views.cat, name="category-page") From experience, the problem is with all the 'watchlist' related URLs. For example, when i am on index view, the path to path("<int:user>/watchlist", views.watchlist, name="watchlist"), is <a class="nav-link" href="{{ user.id }}/watchlist">Watchlist</a> and the url path shows the same - http://127.0.0.1:8000/2/watchlist where 2 is the user id. Then when i go to a url <a class="nav-link" href="categories">Categories</a> the url path followed is http://127.0.0.1:8000/2/categories the '2' should not be there! I specifically hard coded the path in the anchor tag I am facing another problem: when i am at the index view and i click on the anchor tag containing <a href=/{{ user.id }}/{{ item.Title }} where item.Title is say "Magic Broom", the url path i am getting is http://127.0.0.1:8000/2/Magic while it should have been http://127.0.0.1:8000/2/Magic Broom Can someone please explain what's going on here... -
