Django Static files are being served with HTTPS while the running server is HTTP
I'm using Amazon lightsail instance and introduced Certbot into my service on the Nginx-Gunicorn-Django stack in order to serve my site with SSL implemented. I took a snapshot of this server and created a new one which I want to serve without SSL but when the server turns on I can see the page but all images, css, js show ERR_CONNECTION_REFUSED. Which I found the issue comes from searching for these files in HTTPS when I want them to be served in HTTP. Here are some things I've tried Removed SSL Setting Nginx Completely removed Nginx serve and ran server on manage.py 8000 Disabled SSL related settings and DEBUG MODE = True Image shows up if I open url to http://img.jpg How can I solve this issue?

Django form updates front end even if username already exists
Below is my Django form that allows users to update their username and email. If they enter a username or email that's already taken by another user, the form correctly displays an error message. However, the front end still updates with the username or email that they entered. How can I update the else block in views.py below to show the username/email that is actually stored in the database, not the one the user just entered? Screenshot: forms.py class UserUpdateForm(forms.ModelForm): email = forms.EmailField() class Meta: model = User fields = ['username', 'email', 'lat', 'long', 'travel_radius', 'location_name'] widgets = {'lat': forms.HiddenInput(), 'long': forms.HiddenInput(), 'travel_radius': forms.HiddenInput(), 'location_name': forms.HiddenInput()} views.py @login_required def account(request): if request.method == 'POST': u_form = UserUpdateForm(request.POST, instance=request.user) if u_form.is_valid(): u_form.save() messages.success(request, f'Your account has been updated!') return redirect('account') else: #<- HOW CAN I SHOW THE ORIGINAL USERNAME, NOT THE USERNAME ENTERED? stored_user = User.objects.filter(id=request.user.id).first() u_form = UserUpdateForm(request.POST, instance=request.user) u_form.username = stored_user.username # Get the values on this user that are stored in the DB u_form.email = stored_user.email u_form.fields['username'].initial = stored_user.username return render(request, 'users/account.html', {'u_form': u_form} ) else: u_form = UserUpdateForm(instance=request.user) context = { 'u_form': u_form } return render(request, 'users/account.html', context) -
Django REST Fw - How to dynanically create fk relation when neither object exists initially?
[I'm asking about DRF but this question is more about a general approach to a situation like mine] Let's say on my backend I have a Category and a Question model like these: class Category(models.Model): name = models.TextField() class Question(models.Model): text = models.TextField() category = models.ForeignKey( Category, on_delete=models.SET_NULL, null=True, related_name="questions" ) I have a vue frontend in which I have a form that allows me to create categories and questions. The way it's laid out is I have an add button for categories in the form, an add button for questions, and for each question I can select the category it belongs to. All questions and categories are keyed with a uuid in my vue.js frontend, but that's not the id they end up having on the db of course. When I POST my form to the DRF backend, neither the categories nor the questions exist yet, so I can't just send the questions like this: { text, categoryId }. A simple way to handle this could be to send the form like this: categories: [ { name: "cat1", questions: [ { text: "question1" }, // ... }, // ... ] However, the actual structure of my app is more … -
ValueError at /app/ when accessing model data
I am new with django, I've learnt by following the documentation, but it seems django doesn't want to retrieve any data from the model, on a new project.

django.db.utils.OperationalError: (1044, "Access denied for user to database) when having permissions
I'm trying to connect my django project to its MySQL db in an Amazon EC2 instance, but I keep getting the error in the title.

Django 3 - ORM "AND" logic in filtering
I have a Query. qu = Product.objects .filter(color = 'black') .filter(color = 'white') .all() That gives me "And" logic which I'm looking for. Now I want to pass dict of criterions. my_crit = { 'color': 'black', 'color': 'white' } qu = Product.objects .filter(**my_crit) .all() That gives me OR, which is bad for me. So I tried Q. crit1 = Q(color='black') crit2 = Q(color='white') qu = hello = Product.objects .filter(crit1 & crit2) .all() This returns query with 0 results. So the question is - how can I use filter chain (AND logic) with dynamic inputs? (my own dict, etc). -

Django - Edit Or Delete Selected Rows In A Table
I'm trying to select one or multiple items in my table to do some manipulations, such as deleting the selected rows all at once. I want to keep it simple and do everything in html. I'm struggling to pass the status of each checkbox through my POST request. In my views, this is what request.POST returns: <QueryDict: {'csrfmiddlewaretoken': ['mtoFZt1PvlnAsYgEjT...'], 'selection': ['on', 'on', ...]}> How can I access the ID and value of each checkbox in the POST request?

Change URL Path for View Profile Page - Django
How would one go about creating a user-profile page that other users can view without being able to edit the profile unless they are the user? The thing I'm trying to work out is how the url routing would work, is it best practice to store a user's profile on a profile/ or <user_id> page and then load in the individual user's data like recent posts using the username or id passed through the url? Also would this be handled by the one view and template and just use {% if request.user == profile.user %} to display things like edit profile etc? my problem is any user can edit for others there profiles when he edit url for example my id is www.test.com/profile/44/ and other user have this id www.test.com/profile/40/ okay ,, now when i edit the link to be 40 not 44 i can access and edit the second user ! how to fix that models.py : class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) email_confirmed = models.BooleanField(default=False) @receiver(post_save, sender=User) def update_user_profile(sender, instance, created, **kwargs): if created: Profile.objects.create(user=instance) instance.profile.save() def __str__(self): return self.user urls.py : from django.urls import path from blog_app.views import ProfileView urlpatterns = [ path('profile/<int:pk>/', ProfileView.as_view(), name='profile'), ] forms.py … -

Using Django admin application AND disabling session middleware?
I am building a django server for an API that relies on JWT (or Token based - https://www.django-rest-framework.org/api-guide/authentication/#tokenauthentication) authentication for our users. I don't need session based authentication for any purpose. It creates an unnecessary query on each request, and also authenticates users when I don't want to authenticate them (I want browsers to only authenticate when it includes an Authentication header in the request, and stay AnnonymousUser otherwise. This is because it creates issues in some of my middlewares where I verify if I am dealing with a guest or a authenticated user). However, the issue comes when I try to use the admin application as well (I can't imagine building this app without the use of the django admin page). When I remove the session-related middlewares:(django.contrib.sessions.middleware.SessionMiddleware, django.contrib.auth.middleware.AuthenticationMiddleware and django.contrib.messages.middleware.MessageMiddleware) from my settings file, I get the following error when I do a runserver: ERRORS: ?: (admin.E408) 'django.contrib.auth.middleware.AuthenticationMiddleware' must be in MIDDLEWARE in order to use the admin application. ?: (admin.E409) 'django.contrib.messages.middleware.MessageMiddleware' must be in MIDDLEWARE in order to use the admin application. ?: (admin.E410) 'django.contrib.sessions.middleware.SessionMiddleware' must be in MIDDLEWARE in order to use the admin application.

React/Django: Database works, but React Is not Rendering the Views

showing error in map while fetching data in Reactjs after authentication in CRUD django REST api?
i am trying to do a CRUD app with backend in Django Rest Api and in frontend it would be react-hooks. The main functionality will be, after authentication it would show tasks created by the user and only user would see and edit, delete etc his own tasks. i have uploaded the API in heroku and Here is Api link and here is the openapi look. and you can find the source code in the github and here is the codesandbox for frontend FYI: i couldn't link the backend with the codesandbox frontend but in localhost frontend can communicate with the backend django part. i have used corsheaders to separate frontend and backend. i am practicing in this way just because the backend API would be reusable. i am not sure whether it is a professional practice or not. though i couldn't link my api with the codesandbox and it is for the show of my whole code. in dashboard.js, the below part is working: useEffect(() => { if (localStorage.getItem("token") === null) { window.location.replace("http://localhost:3000/login"); } else { fetch("http://127.0.0.1:8000/api/auth/user/", { method: "GET", headers: { "Content-Type": "application/json", Authorization: `Token ${localStorage.getItem('token')}`, }, }).then(res=>res.json()) .then(data=>{ setUserEmail(data.email); setLoading(false) setUsername(data.username) }) } }, []); Here the … -
