Django formset queryset
I have two apps: accounting and projects. Every consumption item has a fk to project. Every production has a fk to a project. Production order has fk to production. produced product has fk to production order. consumption item has fk to produced product. While creating produced line, I want to create consumption line as formset. However, consumptionitemline_to_consume field should show instances from the related project, not all instances.. Below I tried to filter the dropdown however, it just does not work. here is forms class ProductionProducedLineConsumptionLineForm(forms.ModelForm): class Meta: model = ProductionProducedLineConsumptionLine fields = '__all__' widgets = { 'productionproducedline': forms.HiddenInput(), 'produced_kg_scrap': forms.NumberInput(attrs={'class': 'w-full input rounded-md'}), 'produced_kg_wastage': forms.NumberInput(attrs={'class': 'w-full input rounded-md'}), } def __init__(self, *args, **kwargs): production_id = kwargs.pop('production_id', None) # We'll pass this when initializing the formset in the view super(ProductionProducedLineConsumptionLineForm, self).__init__(*args, **kwargs) if production_id: production = ProductionProducedLine.objects.get(id=production_id) project = production.productionorderline.production.project self.fields['consumptionitemline_to_consume'].queryset = ConsumptionItemLine.objects.filter(project=project) # This does not work?

Json on the front is incomplete, how to solve it?
I was serializing the data in django to pass it to bff and then to the front, I tested the requests to see if they were all "ok", the result of the direct request to django is ok, the request from bff is also ok, but when I went to see on the front it was incomplete with some of the fields missing, especially those with a compound name django rest api: { "id": 6, "chatID": XXXXXXX, "chatGroup": "XXXXXTESTXXXX", "firstName": "XXXX", "lastName": "XXXXX", "date": "XXXXXXXXX", "messageUser": "[XXXXXXXXX]", "status": null }, { "id": 7, "chatID": XXXXXXX, "chatGroup": "XXXXXTESTXXXX", "firstName": "XXXX", "lastName": "XXXXX", "date": "XXXXXXXXX", "messageUser": "[XXXXXXXXX]", "status": null }, bff: { "id": 6, "chatID": XXXXXXX, "chatGroup": "XXXXXTESTXXXX", "firstName": "XXXX", "lastName": "XXXXX", "date": "XXXXXXXXX", "messageUser": "[XXXXXXXXX]", "status": "" }, { "id": 7, "chatID": XXXXXXX, "chatGroup": "XXXXXTESTXXXX", "firstName": "XXXX", "lastName": "XXXXX", "date": "XXXXXXXXX", "messageUser": "[XXXXXXXXX]", "status": "" }, front-end (Nextjs) { "chatGroup": "", "chatID": 0, "date": "XXXXXXXXX", "firstName": "", "id": 6, "lastName": "", "messageUser": "", "status": "" }, { "chatGroup": "", "chatID": 0, "date": "XXXXXXXXX", "firstName": "", "id": 7, "lastName": "", "messageUser": "", "status": "" } As I'm using typescript I made a type for the message type: export type MessageProps = { … -
Django app; Default User ID and model field 'Trader ID' not equal
I am creating an app to allow users to enter stock trades, for record keeping. I am using Django's default User model for login and authentication. My intention is to allow the logged in user to view only their own 'Entries', which is my model for stock record entries. To this end, I have created a one to Many relationship in my Entry model named 'trader' which points to the User ID (they should be the same). After logging in though, I don't see ANY trades on the screen even though they have been entered. I checked the Database, and the Entry.trader.id is the same number as the User.id (1 in the case of the first user created). Very strange. What I tried: I tried removing this line from my views.py EntryView class: entries = Entry.objects.filter(trader_id=logged_in_user).order_by("entered_date") and replacing it with: entries = Entry.objects.all() This works (proving that the records are there)but now it shows ALL of the entries. My models.py: from django.db import models from django.core.validators import MinValueValidator, MaxValueValidator from django.urls import reverse from django.utils.text import slugify from django.contrib.auth.models import User class Entry(models.Model): ONEORB="1-Min ORB" FIVEORB="5-Min ORB" ABCD="ABCD" REVERSAL="Reversal" PROFIT="Profit" LOSS="Loss" RESULT_CHOICES = ( (PROFIT, "Profit"), (LOSS, "Loss") ) STRATEGY_CHOICES … -
django forms.ModelChoiceField not populating for edit form
I'm using same view and template for adding and editing the record in django. when I click on edit, all other fields are populated correctly, but modelChoiceField has no value. I've tried the solution Django ModelChoiceField is not filled when editing but not getting the desired results. Here's how I'm defining the field in model category = forms.ModelChoiceField( queryset=Category.objects.all(), empty_label="Select Category", required=True, to_field_name="name" ) Here's how I'm initializing my form form = myForm(request.POST or None, instance=form_instance, initial=models.model_to_dict(form_instance)) if I print the output from model_to_dict(form_instance) it show {'id': 18, 'title': 'test title', 'description': 'test description', 'material': 'blah blah', 'category': 2, 'user': 3} But on the form, model choice field has empty label. How do I populate it with NAME for category having pk=2 in above case ? -

best method to do Django facial recognition by capturing the customer's
Good afternoon, what would be the best way to capture frames from the user's camera to use a function I have in Django views for facial recognition. What I'm trying now is to open a camera for the user on the web and from there remove the frames, but it's not working correctly as it's giving me the error "TypeError: Object of type bytes is not JSON serializable" and also I wanted the user to have that frame around the face saying that the image is being captured. I will send below what I have in views and in my js I appreciate any help or opinion offered @csrf_exempt def process_frame_faceRecognition(request): print("Processando frame...") if request.method == 'POST': frame_data = request.POST.get('frame_data') print(frame_data) frame_data = frame_data.split(',')[1] # Remover o prefixo 'data:image/png;base64,' frame_data_decoded = base64.b64decode(frame_data) frame_data = np.frombuffer(frame_data_decoded, dtype=np.uint8) frame = cv2.imdecode(frame_data, flags=1) # Agora você pode passar o frame para a função compare_faces() face_recognition = FaceRecognition() result = face_recognition.run_recognition(frame) # Verifique o tipo de resultado antes de retorná-lo if isinstance(result, HttpResponseRedirect): return JsonResponse({'message': 'redirecionamento', 'url': result.url}) else: # Coleta os valores do generator em uma lista result_list = list(result) # Codifica a imagem como base64 _, buffer = cv2.imencode('.png', frame) frame_base64 = … -
Why Django does not be deployed easily?
I have been learning Django for a long time, and I always find difficulties in deploying my projects, I often deploy my projects on AWS, and it takes a lot of money, also, the other platforms take a lot of fees to make your Django project deployed on their platforms, After that I decided to move to PHP here I found a difference, -and the difference is in the amount of time, that you need to deploy your project (which is a lot shorter than Django), -and the amount of fees that you need to pay to the platform to deploy your project on (it is 100%100 cheaper than Django), -and there are a lot of platforms for PHP, while Django there are few platforms to deploy your project on, -and PHP is much easier to deploy, there are platforms that just you take your project and drag it then drop it to them, and this is everything. my questions are : 1- Why sometimes you have to take a cloud computer service then you have to install python , and everything in python , then you upload the Django project, it is like you are using it on your … -

Design User class in Django
I use the AbstractUser class to extend my User class. In my User class, there are currently 3 roles: Admin, Lecturer and Alumni. I can use is_superuser, is_staff to solve the problem, however, in the future there may be more roles appearing and if I use the above method it will not be possible to add more roles better. But if I use the additional field role = models.IntegerField(choices=Role.choices, default=Role.ALUMNI) it looks fine. But when using superuser, is_superuser = True and the user's role is Alumni. By the way, I'm working on a project using django, rest_framework. I want Users with the role of Lecturer to be created by the Admin and set a default password, and after 24 hours from the time of account creation, if the Lecturer does not change the password, the account will be locked and the Admin will have to reopen for Lecturer. I wrote two functions save and check_password_expiry but I'm not sure if it works as I want. Can someone solve my current problem, please? class User(AbstractUser): class Role(models.IntegerChoices): ADMIN = 1, "Admin" LECTURER = 2, "Lecturer" ALUMNI = 3, "Alumni" avatar = CloudinaryField(null=True) cover = CloudinaryField(null=True) role = models.IntegerField(choices=Role.choices, default=Role.ALUMNI) alumni = … -
How can we get custom token from dj-rest-auth while authentication?
We are trying to use dj_rest_auth to make social authentication, starting with Google auth, work on a site / app using JWT token pair (access & refresh). Our attempted solution is as follows: Goal: We are modifying the register & login API endpoints provided by dj_rest_auth to return our JWT custom token pair (as returned by the api/token endpoint), instead of the session key. Possible options: Option 1: Extend dj_rest_auth.registration.views.RegisterView with a CustomRegisterView, modifying the perform_create method to return the JWT token pair. Option 2: Let dj_rest_auth.registration.views.RegisterView return the session key & token be in the cookie, but modify the token in the cookie to add the logic in our custom token serializer to add additional fields. The above approaches will apply to Loginview as well. Our questions: Which of the above is better? Our preference is for approach 1 - more consistent with our maintenance & use of tokens before social auth. Is there any concern with the above option 1 - ie having register & login endpoints return the JWT token pair? Assuming Option 1 - what is the best way to do it? We are trying to extend the RegisterView - but it’s unclear which method to … -

Flask as a back-end web programming framework
I'm currently working on a simple project that I wanted it to be my introduction to python web programming. I've wrote a python code of what I needed and I'm working on the interface that I wanted to be a web based one. I choose to work with flask. I wanted to know whether I have to modify the code to be suitable with the framework? and how to manipulate the database since I was working with csv files in my initial code? So basically the code consists of different search algorithms in artificial intelligence (BFS, DFS, A* and hill climbing) that return a path in a map. I wanted to used html, css, js and flask to implement an interface that gives the user option to choose starting and goal states and represent that resulting path in a map. -
Adding the django-parler to admin page in Django admin
I'm working on my Django project and I added django-parler to my Django project. I have added parler in my models.py and that looks like this: class Category(TranslatableModel): translations = TranslatedFields( category_name=models.CharField(max_length=255, verbose_name="Category name"), ) parent = models.ForeignKey('self', null=True, blank=True, on_delete=models.CASCADE) slug = models.SlugField(max_length=200, unique=True, editable=False, default='') def clean(self): if self.parent: if self.parent.parent: raise ValidationError("A category that already has a parent cannot be set as the parent of another category.") def save(self, *args, **kwargs): if not self.slug: base_slug = slugify(self.safe_translation_getter('category_name', self.category_name)) # Ensure uniqueness of the slug slug = base_slug counter = 1 while Category.objects.filter(slug=slug).exists(): slug = f"{base_slug}-{counter}" counter += 1 self.slug = slug super(Category, self).save(*args, **kwargs) class Meta: verbose_name = "Category" verbose_name_plural = "Categories" ordering = ['category_name'] def __str__(self): return self.safe_translation_getter('category_name', self.category_name) Tricky part is that I want slug to be translated not just category name. Also, in admin.py I did it like this: admin.site.register(Category, TranslatableAdmin) And I got it like on images below. I'm happy with the result. What you see on first image, is when you click on categories on admin side, and if I have multiple translations it makes entry for every language. On second image you see how it looks like when you are adding … -
How to Prefetch a group concat field in Django
my question is the following : I have a view table mapped to the Django ORM, with a group_concat field using MariaDB. Is it possible to fetch IDs from this: This view stores data for operators, and each operator can be associated with multiple companies Class OperatorsView(models.Model): id = models.IntegerField(primary_key=True, db_index=True) # fleet_operator_id fleet_operator = models.ForeignKey( "companies.FleetOperator", on_delete=models.DO_NOTHING, null=True ) user = models.ForeignKey( "accounts.MobileUser", on_delete=models.DO_NOTHING, null=True ) operator = models.ForeignKey( "companies.Operator", on_delete=models.DO_NOTHING, null=True ) companies_shared_str = models.CharField( db_column="companies_shared_id", null=True, max_length=4000 ) So I would like to know if the companies_shared_str field is possible to be used in OperatorsView to prefetch in advance, not using a @property because this will lead to N + 1 queries. Any suggestions would be greatly appreciated -

forbidden (403) CSRF was not verified. The request was cancelled
I am logogin with super admin in django project and want to change some properties of users but when i clicked at save button it shows an error as below: forbidden (403) CSRF was not verified. The request was cancelled. Help Reason given for failure: Origin checking failed - https://somedomain.com does not match any trusted origins. In general, this can occur when there is a genuine Cross Site Request Forgery, or when Django’s CSRF mechanism has not been used correctly. For POST forms, you need to ensure: Your browser is accepting cookies. The view function passes a request to the template’s render method. In the template, there is a {% csrf_token %} template tag inside each POST form that targets an internal URL. If you are not using CsrfViewMiddleware, then you must use csrf_protect on any views that use the csrf_token template tag, as well as those that accept the POST data. The form has a valid CSRF token. After logging in in another browser tab or hitting the back button after a login, you may need to reload the page with the form, because the token is rotated after a login.

Django static files 404 errors just for one folder and all images

It does this for all the image files in the template The second type (one folder): for the line <script src="{% static 'sleek-bootstrap/source/assets/plugins/daterangepicker/moment.min.js' %}"> ></script> I get the error "GET /static/sleek-bootstrap/source/assets/plugins/daterangepicker/moment.min.js HTTP/1.1" HTTP/1.1" 404 1958 Django finds all the files in the path /static/sleek-bootstrap/source/assets/plugins/, except those in the daterangepicker plugin folder.
