Updating a group of Django objects in one click
I have a Message model with an 'unread' field set to default=True: class Message(models.Model): user = models.ForeignKey(Profile, on_delete=models.CASCADE) sender = models.ForeignKey(Profile, on_delete=models.CASCADE) message = models.TextField(blank=True) unread = models.BooleanField(default=True) I want to be able to select a group of these objects at once and update their unread status to False on click. Each of them are currently being displayed with a checkbox alongside, and I have a form on top: <form action="{% url 'users:read_message' %}" method="post"> {% csrf_token %} <button type="submit">Mark as read</button> </form> {% for msg in messages %} <input type="checkbox" name="message" value="{{ msg.id }}"> <p>{{ msg.message }}</p> {% endfor %} And here is the view: def message_read(request): if request.method == 'POST': selected_messages = request.POST.getlist('message') for message in selected_messages: read = Message.objects.get(pk=message) read.update(unread=False) return redirect('users:messages') return redirect('users:messages') At the moment my request.method == 'POST' is always returning false. Is anyone able to explain what I've done wrong? -

ML_Model deployment with Django (JOBLIB)
I am trying to deploy ML model with Django. I have done already three of them. At the beginning it worked. Because of some kind of reasons, it stopped working now. What exactly happens. When I enter the data, it should return the list of the entered parameters, and the result. Unfortunately, django model does not return either the entered data or the result. It is interesting that it worked on my first project (https://github.com/RG-911/Car-Price-Prediction.git). Now, it stopped partially (does not return list of entered parameters) working on this project, too. In the second project and third project it returns neither parameters and results. The second project: https://github.com/RG-911/Car-type-prediction.git The third project: https://github.com/RG-911/Mobile-OS-detection.git YOU MAY DOWNLOAD .RAR FILES OF THE DJANGO MODELS. Thanks in advance for the help. -
Sentry doesn't take into account level param for capture_message()
When I call in my code capture_message(level="INFO") sentry marks it as an error. I tried other logging levels, but result is the same. Here are my settings for django: sentry_sdk.init( ... integrations=[ ... LoggingIntegration( level=logging.INFO, event_level=logging.ERROR, ), ] ) Basically I need to mark my custom message as warning. How can I achieve it? -
Django graphene generate schema
Is there a way how to dynamically generate Django graphene schema from Django models? I am trying to reduce my code as I have a lot of models and each model has to have in my schema.py file a Query, Type Class, and a resolve function. This is becoming overwhelming to maintain as my amount of models and model fields grow. class blog_postType(DjangoObjectType): class Meta: model = models.blog_post filter_fields = get_all_model_fields(models.blog_post) class Query(ObjectType): post = graphene.List( blog_postType, id=graphene.Int(), title=graphene.String(), ) def resolve_blog_post(self, info, **kwargs): return model.blog_post.objects.all() schema = graphene.Schema(query=Query,mutation=Mutation) this is a small example, which grows by having a huge amount of models. -
Update custom UserAdmin's `change_password_form` to use PasswordChangeForm
Using django 2.2. I have a custom user inheriting from AbastractUser, and the default user password change form to include the user's old password. I've found that django includes PasswordChangeForm which includes old password entry along with new_password1, new_password2. I've tried to set change_password_form but when I click the related user "change password" link, the resulting password change view displays no fields. from myapp.models import MyCustomUser from django.contrib import admin from django.contrib.auth.admin import UserAdmin from django.contrib.admin.forms import PasswordChangeForm @admin.register(MyCustomUser) class MyCustomUserAdmin(UserAdmin): list_display = list(UserAdmin.list_display) list_display.remove("first_name") list_display.remove("last_name") ordering = ("-date_joined",) search_fields = ("username", "email") change_password_form = PasswordChangeForm fieldsets = ( (None, {"fields": ("username", "client", "password")}), (_("Personal info"), {"fields": ("email", "confirm_email")}), (_("Permissions"), {"fields": ("is_active", "is_superuser")}), ) How can I update the my CustomUserAdmin to use a form that forces the user to re-entry their original password? -
'PictureDetail' object has no attribute 'user'
When I am not logged in and click on the Download link, this error appears. AttributeError at /pictures/5/ 'PictureDetail' object has no attribute 'user' I want the picture to be downloaded only by the user who has at least one uploaded picture. I could put LoginRequiredMixin as an attribute of the PictureDetail class and that would solve the problem, but I only need to hide the Download link and not the whole picture. views.py class PictureDetail(DetailView): model = Picture @login_required def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) if Picture.objects.filter(user=self.request.user).exists(): context["download"] = True return context models.py class Picture(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) picture_detail.html {% if download == True %} <p class="card-text"><a href="{{ picture.picture.url }}">Download</a></p> {% endif %} -
Django 3.1 deployment on Heroku - collectstatic fails
I have seen very similar posts on this issue on this and other websites. However, most of the answers I found were either outdated, sloppy, or just did not work.

DRF simple jwt getting auth token from a user instance OR change username and password combination
I have a chat app that uses the same authentication method as in WhatsApp. Normally I would get the jwt auth token with this: path('api/token/', ObtainPairViewToken.as_view(), name='token_obtain_pair'), However This asks for both username and password while my user model is using phone_number and a validation code instead. Is there any way to change this? username ======> phone_number password ======> phone_code (The validation code) The second way Is to pass the user instance and get the auth token from it somehow my Login view @api_view(['POST',]) def loginuser(request): if request.method == 'POST': phone_number = request.data.get('phone_number') try: user = User.objects.get(phone_number=phone_number) if int(request.data.get('phone_code')) == user.phone_code and user.phone_code: # user.phone_code = None # user.save() return Response({'phone_number': phone_number}, status.HTTP_200_OK) else: return Response({'error': "Invalid code"}, status.HTTP_400_BAD_REQUEST) except Exception as error: return Response({'error': error}, status.HTTP_500_INTERNAL_SERVER_ERROR) my user model: class User(AbstractUser): phone_number = PhoneNumberField(unique=True) username = models.CharField(max_length=30) password = models.CharField(null=True, blank=True, max_length=20) about = models.CharField( max_length=190, default="Hi, I use Orgachat!", blank=True, null=True) ... phone_code = models.IntegerField(blank=True, null=True) USERNAME_FIELD = 'phone_number' def __str__(self): return str(self.username) # Save auth token, I know this should be in signals.py but whatever @receiver(post_save, sender=User) def create_auth_token(sender, instance=None, created=False, **kwargs): if created: Token.objects.create(user=instance) -

Show customer orders in one model Django
I am creating an eCommerce website for my client. I am completely new to Django. I am following a tutorial: creating an eCommerce Django website. In tutorial instructor creates 3 models: Customer, Order, Order_Items. I did not like the model setup in that tutorial. When a customer places an order, in database order created and seperate order_items being created and they are being assigned to order. I want something different like in Wordpress Woocommerce, when a customer places an order, in the admin dashboard you can see Customer order, and when you view that order it shows products and their price, quantity, and total price in one place. I want to make an Order model that contains and shows: customer name, products, quantity, and total product price. As far as I know, Order and Order_item is a common solution for creating order but for the website admin(for my client), it would be very hard to understand and keep track of customer orders. I couldn't find any solution on the Internet. It would be great if you could give me an idea of how to solve this problem. Thanks in advance! -
Django share users in different databases causes 500 and 403 errors
The goal I want Doccano to use the users that are saved in my other app (app2) as its own users, instead of Doccano keeping its own users. These are both Django databases, so i assume these are not doccano specific issues The problem The connection between the users work, i can login in doccano with app2 users. when in the /projects page an 500 internal server error arises on the website and on the terminal app2 prints: "ERROR: relation "api_project" does not exist at character 363" When creating a new project a 403 Forbidden arises when doing a POST to /v1/projects What i did I am currently running the Doccano Backend, nginx and postgres in their containers and running app2 and the postgres_app2 in containers as well. Doccano backend shares a (docker-compose)network with Doccano postgres and another network with postgres_app2. doccano/app/app/settings.py has both databases and a link to the router: # settings.py DATABASES = { 'default': { 'ENGINE': 'django.db.backends.sqlite3', 'NAME': path.join(BASE_DIR, 'db.sqlite3'), }, "app2_db": { "ENGINE": "django.db.backends.postgresql", "NAME": "postgres", "USER": os.getenv("POSTGRES_USER", "user_app2"), "PASSWORD": os.getenv("POSTGRES_PASSWORD", "pass_app2"), "HOST": "postgres", "PORT": 5432, } } DATABASE_ROUTERS = ['app.authRouter.AuthRouter'] with the AuthRouter.py looking like this: # AuthRouter.py class AuthRouter(object): def db_for_read(self, model, **hints): if … -
Django with SQLite - Database is locked - does it throw error? When does it occur?
I'm using Django + sqlite for my hobbist project (Gallery script). The whole script isn't very write-heavy. The only writes to database is incrementing views for each browsed photo. Today I was browsing logs and noticed few "Database is locked" errors. I know this is sqlite's issue, but I'm not sure how Django handles it. I'm unable to reproduce the error on my own, therefore I have two questions. If the "Database is locked" error occurs during the user visit (number of views update is called from PhotoDetailView) does it end up in 500 error or the user stills sees the photo? Does it fail silently (counter not updated, print to logs)? How does the single no parallel writes rule work for SQLite? Is it single write at given time for whole database or table? Item? Any ideas how can I manually lock the database to reproduce the "database is locked" error? -

Template inheritance with dynamic content
Is it possible to make one sub-template inherit a div with dynamic content from an upper level template? For eg., there are 3 templates as following: base.html <!DOCTYPE html> <html> <head> </head> <body> <div id="content"> {% block content %} {% endblock %} </div> </body> </html> level_1_template.html {% extends "base.html" %} {% block content %} <div id="dynamic-level1"> ...some elements here that depend on variable {{ level_1_var }}} </div> {% block level2_content %} {% endblock %} {% endblock %} level_2_template.html {% extends "level_1_template.html" %} {% block level2_content %} ...doing level 2 stuff here ... {% endblock %} In this generic example, level_1_var variable is passed into the corresponding view for that template and not the view for level_2_template.html When rendering level_2_template.html, div dynamic-level1 is not rendered. Is there a way to make this inheritance possible? Of course, one way is to repeat the whole thing in level_2_template.html and to pass the variable level_1_var to the corresponding view. But this does not seem like a decent (or DRY) way to do. Thanks. -
