Any help or explanation is welcome! Thank you. -
Can i have Django urls and Vue routes in the same project?
I started a Django app and i created the whole authentication layer using Django-Allauth, it already has quite some features such as email confirmation, password reset and two factor authentication. Now i realized that, since my app will be heavily interactive and with a lot of real time features, i'm going to need a Vue SPA to use with Django, so i'm thinking of creating the Vue SPA on the same server and domain and have Django as a Rest API. Here is my problem: since i already made the whole authentication part using Django templates and Django urls, if i separate the rest of the frontend from the backend, will i have to rewrite everything? Is it possible to have a Vue app and a Django backend app separated on the same domain where authentication is handled by Django templates and all the rest is a Vue app with vue routes and all the other interactions are handled by Django Rest Framework endpoints? So maybe something like this: urlpatterns = [ path('accounts/signup/', SignUpView.as_view(), name='signup'), #Django template path('accounts/login/', LoginView.as_view(), name='login'), #Django template ... ] And these are the only Django-handled urls where the page is rendered by Django views. Once … -
Form is not rendering with password_reset_confirm_view
I am trying to implement the Password Reset from Django auth views. The HTML is rendering and everything seems to work fine but the form is not visible. It shows None on the form field. I tried inspecting the element and it turns out to be blank inside the HTML form element. Here is the views of inbuilt reset password confirm: class PasswordResetConfirmView(PasswordContextMixin, FormView): form_class = SetPasswordForm post_reset_login = False post_reset_login_backend = None reset_url_token = 'set-password' success_url = reverse_lazy('password_reset_complete') template_name = 'registration/password_reset_confirm.html' title = _('Enter new password') token_generator = default_token_generator @method_decorator(sensitive_post_parameters()) @method_decorator(never_cache) def dispatch(self, *args, **kwargs): assert 'uidb64' in kwargs and 'token' in kwargs self.validlink = False self.user = self.get_user(kwargs['uidb64']) if self.user is not None: token = kwargs['token'] if token == self.reset_url_token: session_token = self.request.session.get(INTERNAL_RESET_SESSION_TOKEN) if self.token_generator.check_token(self.user, session_token): # If the token is valid, display the password reset form. self.validlink = True return super().dispatch(*args, **kwargs) else: if self.token_generator.check_token(self.user, token): # Store the token in the session and redirect to the # password reset form at a URL without the token.

Django logger's level is not tracking INFO messages even though level is set to ERROR
I'm trying to create a simple logger, and I only want the logger to record ERROR (and not INFO or WARNING). I've set the level to logging.ERROR, and using messages using logger.info correctly does not appear. However, the funny thing is system message with level "INFO" are being tracked (2021-03-18 17:14:43,251 - django.utils.autoreload - INFO - file changed, reloading.). I don't really understand why this is happening since the example is INFO and not ERROR, and I'm not directly calling it use logger.info. import logging def create_logger(app_name): """Create a logging interface""" logging.basicConfig( filename='logs/example.log', level=logging.ERROR, encoding='utf-8', format='%(asctime)s - %(name)s - %(levelname)s - %(message)s') logger = logging.getLogger(app_name) return logger logger = create_logger('test') # this is correctly logged logger.error('Test error') # this is correctly not logged logger.info('Test info') -
Djano remot user login via java script
In my django application hosted on heroku (https://ers-heatscreen-app.herokuapp.com) , i would like to authenticate users from an existing customer login on a productive homepage which is solved with java script. So when they login at https://shop.ers-heatscreen.com/login i would like to take the existing user an create a new user/login with existing user in my application. I have invested a ton of time in reading stackoverflow and django documentation, but cant puzzle things together.... Somehow is the best solution, to set a remote_user in django and solve the problem with django MIDDLEWARE = [ 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.contrib.auth.middleware.RemoteUserMiddleware', ] .... AUTHENTICATION_BACKENDS = [ 'django.contrib.auth.backends.RemoteUserBackend', ] Maybe you have some hints/code snippeds/links for me to point me to the right direction. Would really appreciate any help. If you need some more information, i can post further information anytime. -
How to show products & orders of related merchants accounts in django rest framework?
I built an e-commerce project using Django rest framework. For now, the admin can add products directly from the default django backend. Now, the client's requirements have increased, and we have to build a merchant dashboard. Now there will be many seller accounts who will be using that dashboard after registering as a seller from the frontend. Now, in that dashboard (in the frontend), I have to show the products added only by that merchant. For eg: Mobile phone merchants should be able to see only their products ie phones and clothes merchants should be able to see their products only after adding them. The same goes for the order view as well. Until now I haven't associated the user field in the products as it was not required. Also, the order is not done by the seller, but by customers only. Hope I have explained. My models: class Product(models.Model): AVAILABILITY = ( ('in_stock', 'In Stock',), ('not_available', 'Not Available',), ) WARRANTY = ( ('no_warranty', 'No Warranty',), ('local_seller_warranty', 'Local Seller Warranty',), ('brand_warranty', 'Brand Warranty',), ) SERVICES = ( ('cash_on_delivery', 'Cash On Delivery',), ('free_shipping', 'Free Shipping',), ) category = models.ManyToManyField(Category, blank=False) brand = models.ForeignKey(Brand, on_delete=models.CASCADE) collection = models.ForeignKey(Collection, on_delete=models.CASCADE) featured = models.BooleanField(default=False) … -

GeoDjango + Postgis missing functions
So I've been using a Postgres database with the extension Postgis installed, and then using a Django setup to draw spatial data on a Leaflet OpenStreetMap. It has been a bit difficult translating my sql queries to the database functionality that Django is using whenever you're communicating with your database. Often I seem to be missing Postgis functions such as ST_LineCrossingDirection or ST_FrechetDistance. How do I get to use those functions along with .annotate and .filter from Django without having to write custom sql queries and executing those? I've tried to look into F() and Func() from Django as well, but I don't think that solves my issue as it seem to be using built in aggregate functions. I also tried to execute RawSQL in an annotate function to perform the function ST_LineCrossingDirection but it would require me to write a WHERE clause and the condition is something I'm not aware of until I get to the filter() call where I'm using intersects() between two geometries. Anyway .. If anyone knows how to use what I assume is missing Postgis functions please let me know. Because my code is getting quite messy and ineffective. Thanks, and all help is appreciated! -
Connect fields from 2 models with a primary key
I'm working on an already built project. There are 2 different model, product and stock. Products model has field which is sub_category and stock has main_category. Stock has a product_id which is a foreign key to the Product. I also need to get information from Product which is product_sub_category with product_category_id in a serializer. class Product(BaseModel): product_id = models.CharField(default=randomword(5), null=False, blank=True, max_length=100, unique=True) product_sub_category_id = models.ForeignKey(Product_sub_category, on_delete=models.SET_NULL, null=True, blank=True) class Vendor_Stock(BaseModel): vendor_id = models.ForeignKey(Vendor_management, on_delete=models.SET_NULL, null=True, blank=True) product_id = models.ForeignKey(Product, on_delete=models.SET_NULL, null=True, blank=True) product_category_id = models.ForeignKey(Product_category, on_delete=models.SET_NULL, null=True, blank=True) What would a serializer look like for this? -
Upload python script and load/use it in runtime in django
I need to upload user created python script and load/use it in runtime in django. I tried several approaches like using importlib and other django module like SourceFileLoader. But it seems like the import is failed with 'Permission error'. Ideally, I would like to store the uploaded file in a folder which is at the level of my django project. What's the correct approach for this functionality, particularly the module loading part? -
How to handle editing conflicts in Django forms?
Imagine the following situation: Two users, Alice and Bob, are using a Django form to edit the same object simultaneously. For the purpose of this example, let's use the following model: class Book(models.Model): title = models.TextField() description = models.TextField() Alice edits the book to change its title. Meanwhile, Bob edits the book to change its description. Now, if Bob is the last one to click the "Save" button, his form will "win" and only the description of the book will have been changed. Otherwise, if Alice is the last one to save, only the title will have been changed. Ideally, however, after both forms have been saved, the database should contain the title from Alice, and the description from Bob. I can think of a few possible solutions to prevent this from happening: Locking the form. As soon as Alice requests the book edit form, she acquires a lock that is released after she clicks "Save". When Bob tries to request the same form, he could get an error or warning message that Alice is already editing the same book. The problem here is if course dealing with stale locks. Checksumming the data being edited. The form could contain a … -
Django: maintain sessions across multiple domains with different backend
I have two websites hosted on the same server (aws instance), let's say: web1.domain.com and web2.domain.com Every time a user access one website or another, they will have to log in. If a user accesses from web1 (already logged in) to web2, I want to avoid the user having to log in again. The backend is different: web1 (Python, django) web2 (PHP, mediawiki) Both websites use Mysql and Apache server. I have found this but it does not solve my question completely: Django: maintain sessions across multiple domains I would like to know if there is any way to achieve it. For now, options such as SSO via SAML are ruled out due to complexity. -
Auto printing orders from sql using django/laravel
Is there any possibility to create app (django, laravel) - that would get data from database, table called orders and would automatically create pdf with data and download it? Let's say, i've got 5 new orders, each for different address and different goods. App should automatically create pdf and download for each of those 5 orders. It could also be a react app getting orders from API. Is this possible? Thanks in advance. -
