Django local model inside other model that consists from 2 models
To make it clearer, I want to create an e-commerce app for installment stores I prepared a short HTML template at the bottom of the question I have the following model: class App_form(models.Model): #This is the head model id_customer = models.CharField(max_length=200) name = models.CharField(max_length=150, unique=True) phone_regex = RegexValidator(regex=r'^\+?1?\d{9,12}$', message="Phone number must be entered in the format: '998981234567'. Up to 12 digits allowed.") phone_number = models.CharField(validators=[phone_regex], max_length=13, unique=True) #Models which I should combine and which will be named as: products_with_period model and it should belong only and only to this App_form model warehouse = models.ManyToManyField(Warehouse) product_period = models.OneToOneField(Product_period, on_delete=models.CASCADE) def __str__(self): return self.surname #Product period class Product_period(models.Model): product_period = models.CharField(max_length=200, unique=True) product_percent = models.FloatField() product_periodvalue = models.FloatField() def __str__(self): return self.product_period #Warehouse model class Warehouse(models.Model): category_product = models.ForeignKey(Category_product, on_delete=models.CASCADE) product_name = models.CharField(max_length=200, unique=True) condition = models.BooleanField(default=False) amount = models.IntegerField() barcode = models.BigIntegerField() f_price = models.CharField(max_length=255, null=True) created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now=True) def __str__(self): return self.product_name What I want to achieve in my Rest Api out only from combined products_with_period model products_with_period = [{ id: 1, product_name: " ", product_fprice: " ", product_period: { "id": 2, "product_period_name": " ", "product_period_percent": " ", }, { id: 2, product_name: " ", product_fprice: " … -
django app getting error 500 on heroku, but runs fine locally
I'm getting server error 500 when I deploy my app to heroku. The logs show an issue with staticfiles, even though I'm serving static and media from an S3 bucket: ValueError: Missing staticfiles manifest entry for 'images/favicon.ico' What's odd is that run I run locally, even with DEBUG=False, the app runs fine and I verified that the images are loading from the S3 bucket (both media and static).

Keeps getting CSRF-related 403 Error even when using CSRF exempt decorator [duplicate]
I have just crafted a LoginView and been testing on Postman. However, it keeps throwing a 403 error saying, "CSRF verification failed. Request aborted. You are seeing this message because this site requires a CSRF cookie when submitting forms." even after I have adjusted my view like so with csrf exempt decorator: import json import jwt from psr.settings import SECRET_KEY from django.http import HttpResponse, JsonResponse from django.contrib.auth.forms import AuthenticationForm from django.contrib import messages from django.contrib.auth import login, logout, authenticate from django.contrib.auth import views as auth_views from django.views.decorators.csrf import csrf_exempt from .models import User class LoginView(auth_views.LoginView): @csrf_exempt def post(self, request): form = AuthenticationForm(data = request.POST) if form.is_valid(): user = authenticate(email=request.POST['email'], password=request.POST['password']) if user is not None: messages.add_message(request, messages.SUCCESS, "Welcome back, {}".format(user)) login(request, user) token = jwt.encode({'id': user.id}, SECRET_KEY, algorithm='HS256').decode('utf-8') return JsonResponse({'token': token}, status=200) Is there something I am missing here? Why wouldn't this decorator be enough to circumvent this csrf requirements? Thanks a lot in advance! -
Django view not sending context data to ReactJS/Axios application
It appears I have come across very strange behavior. I am building a ReactJS+Django 3.0 application. Here is the problem... I have a <form onSubmit={handleSubmit}> that wraps the form on the frontend. const handleSubmit = (e) => { e.preventDefault(); axios.post(paths.login, qs.stringify({ email: emailVal, password: passwordVal })); } This works perfectly fine in sending data to the Django view! But when I try to then pass context variable through the Django view, it just fails completely. Meaning, def login(request): data = {} ''' Handle Logging in ''' if request.method == 'POST': login_form = forms.LoginForm(request.POST) if login_form.is_valid(): user = login_form.authenticate_user() #login(request, user) return redirect('home') else: data['errorMessage'] = '' for field, errors in login_form.errors.items(): for error in errors: data['errorMessage'] += error print(data) return render(request, 'index.html', context=data) Given this, the data dictionary will be empty at first, but even when the print(data) shows that the data dictionary is populated, the context data that is sent to the index.html file is still empty. WHY MIGHT THIS BE? I've been stuck on this forever. I can work around this if I just use form submission instead of axios like this: <form method='POST'> However, I need to use axios. SOS -
Generate Additional Table For Individual Units Which Are Part Of A Collection
https://imgur.com/TPCjrkS This is a simplified version of the database Ive designed. Users can enroll in Modules, Packages, or both. Modules are individual units while Packages are collections of many units. Therefore a Package can be thought of as many Modules. Each Module a Student enrolls in has an Extra_Module_Data table (Django Through) which stores data unique to that Student/Module (eg: a boolean variable 'complete' which a teacher can set to True when his student finishes that Module). This works fine when a Student enrolls in a single Module. However, when a Student enrolls in a Package the Modules in that Package do not have an Extra_Module_Data table attached to them. I cant figure out how to attach an Extra_Module_Data table to every Module, regardless of if it is enrolled in via a Module, or a Package of Modules. class Student(models.Model): individual_modules = models.ManyToManyField(BaseModule, blank=True, through='modules.ExtraModuleData') module_packages = models.ManyToManyField(ModulePackage, blank=True) class BaseModule(models.Model): task_type = models.CharField(max_length=200) topic = models.CharField(max_length=200) class ModulePackage(models.Model): individual_modules = models.ManyToManyField(BaseModule, blank=True) name = models.CharField(max_length=200) class ExtraModuleData(models.Model): base_module = models.ForeignKey(BaseModule, on_delete=models.CASCADE) student = models.ForeignKey('users.Student', related_name='extra_module_data', on_delete=models.CASCADE, default=None) completed = models.BooleanField() Thank you. -

Django changing password issues
I have a Django site which authenticates users using an email and a password. Currently, users and their passwords are created in the admin panel, and then users can signin with this email and password. That all works well. The problem occurs once I attempt to change the password, as when either using the command line tool to change the user password, using my custom view, or using Django's built in view, I can no longer login as the user using the old or the new password. I'm thinking it is an error with the salting, because in the admin panel looking at users with unchanged passwords, the password field looks like so: Invalid password format or unknown hashing algorithm., but in the password field for users with passwords I attempted to change the field looks like this: algorithm: pbkdf2_sha256 iterations: 150000 salt: *********** hash: *******************************************.

Why has my django site suddenly gone down? What does the log mean?
I have a Django site on a supported webhost. The site has suddenly gone down today. I'm adamant that I didn't make any file changes and haven't touched this particular site for about a month. Today it's stopped working and all the webhost technical support can do is give me the log and it's not obvious what the problem is (shown below). I get a very generic 'phusion' webserver error when I attempt to access the site 'This site can't be accessed. This issue is being looked at' or something similar, nothing useful there. My only option now is to do a complete server rewind, I'm a little bit hesitant and would prefer to know what the problem is and whether it can be fixed. Can anyone help please?

Set background color of table row based on local value in view (Django)
This isn't really specific to any sort of code so I'll just describe what I'm trying to figure out how to do. I have a local value in my view that corresponds to an object id for one of my models. I want to set the background color of a row in a table created with django-tables2 if that row has a record.pk equal to that id. I think there is probably a way to do this using row_attrs by giving a row attribute to each row that is essentially a T/F value. I'm just not sure how I can do this dynamically. Any suggestions? -
Custom Sort for Column Values in Django SQLite/Python

Python requests saving broken images in kubernetes cluster pod container
I have a django application running in a docker container that downloads images from another server using python requests package. It saves the image using a method on a model like the following: class MyModel(models.Model): preview_image = models.ImageField( upload_to=user_directory_path, height_field=None, width_field=None, max_length=100, ) def user_directory_path(self, instance): return 'my/path/' def save_preview_image(self, image_url): result = requests.get(image_url) self.preview_image.save(result.url, ContentFile(result.content), save=True) self.save() MyModel.save_preview_image gets the image from a provided URL and saves in at the path provided. When I run it in my docker container locally on my system, it saves the image correctly but when I run it in a container in my Kubernetes cluster pod., it saves a broken png image, a file which fails to open. I am wondering what's wrong and if anyone has experienced this issue before. I am running it inside Google Cloud Platform's Kubernetes Engine. Any suggestions will be appreciated. -

Django Checkbox Automatically Update Database

Developiing an Online Pentesting Tool
Thanks for considering my question. I needed to create a tool that allows users to test the vulnerability of their site. i tried sqlmap and D-Tect. However, I want to know how I can make it into a flask or django application where the sqlmap scripts will be called when a user makes a URL input. from sqlmap import sqlmap def test(): execute(sqlmap.py - d "mysql://admin:admin@192.168.21.17:3306/testdb" - f --banner --dbs --users) if __name__ == "__main__": test() I am not sure of the way the syntax would go but something related. Also, other recommendations of tools to use would also be great. Any help on this would be appreciated. Thanks. -
Get username in model with extended user
At the moment, I get the user id when I create a new article. I would like also to have the username in the model (I'm using DRF with React, so it would save me a get request just for the username). models.py: class Article(models.Model): title = models.CharField(max_length=100) user = models.ForeignKey( User, related_name='Article', on_delete=models.CASCADE) serializers.py: class ArticleSerializer(serializers.ModelSerializer): user = serializers.PrimaryKeyRelatedField( read_only=True, default=serializers.CurrentUserDefault()) class Meta: model = Article fields = ['id', 'title', 'user'] def save(self, **kwargs): kwargs["user"] = self.fields["user"].get_default() return super().save(**kwargs)
