Connection to the another DB not created by Django
I have Django project and want to look the another db (not default db created by Php Symfony) Django can set up two DB in settins.py DATABASES = { 'default': { 'ENGINE': 'django.db.backends.mysql', "NAME": config("DB_NAME"), "USER": config("DB_USER"), "PASSWORD": config("DB_PASSWORD"), "HOST": config("DB_HOST"), "PORT": config("DB_PORT"), 'OPTIONS': { 'charset': 'utf8mb4', 'init_command': "SET sql_mode='STRICT_TRANS_TABLES'" }, } 'extern': { 'ENGINE': 'django.db.backends.mysql', 'NAME': config("DB_EXTERN_NAME"), 'USER': config("DB_EXTERN_USER"), 'PASSWORD': config("DB_EXTERN_PASSWORD"), 'HOST': config("DB_EXTERN_HOST"), 'PORT': config("DB_EXTERN_PORT"), } } and set models.py for example class Area(models.Model): class Meta: db_table = 'my_area' However it requires to change the extern database when python manage.py makemigrations,python manage.py migrate I just want to reference the extern db not alter. Is there any good practice?? -
Using DRF + frontend framework with Django froms
Background I ran into a really annoying problem here. I've decided to use Svlete as my frontend. Also, I have a lot of endpoints in my REST api that expect form data. In the past I would just forms.py in my app's directory and then add a form like: class ProductsModelForm(forms.ModelForm): class Meta: model = Product fields = ( 'name', 'weight', ) class ProductForm(forms.Form): name = forms.CharField() weight = forms.IntegerField() And would then use <form method="post"> {% csrf_token %} {{ form.as_p }} <button type="submit">Submit</button> </form> In the HTML template. All cool. DRF + Frontend Framework Obviously I still have the form in the forms.py but now I have to define the form in the fronend too. And with bigger forms it gets really annoying because I always have to compare that I have every field in my frontend form that I have defined in the django backend form. Is ther any solution to this? -
Trying to make a form with 2 inputs
I have two different forms in my register page as the one to one relationship in one of the model will show a drop down box therefore I am using the second models field where the user will have to input the field. How would I make it so when the forms are valid, the 'SNI' will save to the first form and not the second.

Django dont create a new instance of a many-to-many field if its field already exists in db, instead increment another field
I have the following classes in my Models.py (removed unrelated fields & classes) class Size(models.Model): prod_size = models.DecimalField(max_digits=3, decimal_places=1) quantity = models.IntegerField(default=1) class Product(models.Model): sizes = models.ManyToManyField(Size, related_name='products') Currently, if I go under a existing product from django admin and add a new size to an existing product with an existing prod_size value (i.e. prod_size = 8.5 with product_id = 4 in the intermediate table) a new Size object (with its new size_id and product_id = 4 in the intermediate table) and prod_size = 8.5 with quantity = 1 in the Size table are created. I would instead like to increment the quantity field of the existing Size object by one in the database, how can I achieve this? -

Pytest / Django: How to change a decorator that is defined during build time?
I am making a network request and give it a 10 second timeout. The timeout is raised by a decorator that reads the time limit from settings, so it looks like this: @timeout(settings.TIMEOUT). The problem is that I want the test to be super fast, so I change the timeout to 0.1: settings.TIMEOUT = 0.1 The problem is that the decorator is already initialized (I might be using the wrong word) by the time I try to test it. So the decorator is created/defined at build time, then I change the settings, but too late, the decorator doesn't read the updated setting again. Here is a simplified version: ############## settings.py ############### TIMEOUT = 10 ############### request_maker.py ############### from timeout_decorator import timeout from django.conf import settings from time import sleep class MakeRequest @timeout(settings.TIMEOUT) def make_the_request(self): sleep(100) ############### tests.py ############### import pytest from timeout_decorator import TimeoutError from request_maker import MakeRequest def test_make_request(settings): settings.TIMEOUT = 0.1 mr = MakeRequest() with pytest.raises(TimeoutError) as e: mr.make_the_request() # < Even though TIMEOUT is 0.1, it actually times out for 10 seconds How can I change the code so that during production, it is @timeout(10) and during testing it is @timeout(0.1)? -

Embedding http requests into Qt c++ application
I apologize if this is the wrong location to be asking this, let me know and I'll remove it and post it in the right area. I was wondering about standards for performing http requests in a Qt desktop application. For example, I want to create a tool that will register users with a Python based Django application which has a database of users. However, there's a problem here. Do I just hard code the URLs for development and release like this? #ifdef _DEBUG std::string register_url = "http://localhost:3000"; #else std::string register_url = "https://api.mywebsite.com"; #endif I feel like hard coding urls like this is bad practice but I don't know any other way of doing this. Should I use an .ini file? Environment variables? What's the standard for when you have multiple different request URLs? Like I will have the following URLs: /login /register /request_json_web_token /logout /refresh_token Am I supposed to hard code a list of URLs in a header file somewhere? What do you guys do? What's the standard way of doing this? Make monolithic headers full of URLs? -
django raw sql in models with ForeignKey
Let's say this pseudocode represents models to work with class Quiz(): name = models.CharField() class Answer(): quiz = models.ForeignKey(Quiz) answer_text = models.CharField() I would like to trace raw SQL, so let's also import from django.db import connection print(Answer.objects.all().select_related('quiz').query) ok, here we have inner join under the hood >>> a = Answer.objects.all() >>> print(a[0].quiz.query) however the latter example throws AttributeError: 'Quiz' object has no attribute 'query' Could you tell if there are any ways of tracing raw sql more effectively? Which way is the best? I'm practicing more complicated prefetch_related and select_related queries. Thanks -
Settings.BASE_DIR in django returning Windows path instead of Base directory
I ran these commands in the python shell from django.conf import settings print(settings.BASE_DIR) This returned the project's absolute path as expected "C:/Users/User/Desktop/Project" But this was not the case when I tried accessing the same function in a function inside my custom filter, in which it started to return the windows path "C:/" instead. filter.py import os from django import template import moviepy.editor import datetime from django.conf import settings register = template.Library() @register.filter(name='vduration') def vduration(videourl): video = video = moviepy.editor.VideoFileClip(os.path.join(settings.BASE_DIR, videourl)) video_time = int(video.duration) video_time = str(datetime.timedelta(seconds=video_time)) return video_time in my settings.py from pathlib import Path import os BASE_DIR = Path(__file__).resolve().parent.parent Does anyone know what could be going on? -
Python Social Auth grabbing access token for user
I would like to create a custom user with a username, email from the social pipeline using Google OAuth2. If there is a user already associated with that email, username then just attach the access token to that account otherwise create the account but it should get a way to access it through pw after creation? Maybe set a default pw or just delete the account after login? I was looking into pipelines and saw something like this where if backend was something like facebook I could get the values out into a new custom user. { 'username': 'foobar', 'access_token': 'CAAD...', 'first_name': 'Foo', 'last_name': 'Bar', 'verified': True, 'name': 'Foo Bar', 'locale': 'en_US', 'gender': 'male', 'expires': '5183999', 'email': 'foo@bar.com', 'updated_time': '2014-01-14T15:58:35+0000', 'link': 'https://www.facebook.com/foobar', 'timezone': -3, 'id': '100000126636010', } pipeline: def save_profile(backend, user, response, *args, **kwargs): if backend.name == 'facebook': profile = user.get_profile() if profile is None: profile = Profile(user_id=user.id) profile.gender = response.get('gender') profile.save() SOCIAL_AUTH_PIPELINE = ( 'social_core.pipeline.social_auth.social_details', 'social_core.pipeline.social_auth.social_uid', 'social_core.pipeline.social_auth.auth_allowed', 'social_core.pipeline.social_auth.social_user', 'social_core.pipeline.user.get_username', 'social_core.pipeline.user.create_user', 'path.to.save_profile', # <--- set the path to the function 'social_core.pipeline.social_auth.associate_user', 'social_core.pipeline.social_auth.load_extra_data', 'social_core.pipeline.user.user_details', ) My current custom user: class Profile(AbstractUser): bio = models.TextField(max_length=100, blank=True,null=True) phone_number = PhoneNumberField(max_length=25, region='US') birth_date = models.DateField(blank = True, null = True) is_doctor = models.BooleanField(default=False) date_created … -

Display data from multiple tables in one Template
I'm trying to create a dashboard for orders placed by a customer. I've got multiple tables, but the two I'm dealing with is "Order" and "Order_Detail". From the "Order" table, I need to display Customer, Status, and Required_date, from the "Order_Detail" table, I need Product. I'm able to access the data but I can figure out how to display all the records at the same time on one page. models.py class Order(models.Model): STATUS = ( ('New', 'New'), ('Ready For Fullfillment', 'Ready For Fullfillment'), ('Fullfilled Ready For Delivery', 'Fullfilled Ready For Delivery'), ('Out For Delivery', 'Out For Delivery'), ('Delivered', 'Delivered'), ) order_date = models.DateTimeField(auto_now_add=True, null=True) required_date = models.DateTimeField(auto_now_add=True, null=True) status = models.CharField(max_length=200, null=True, choices=STATUS) note = models.CharField(max_length=1000, null=True, blank=True) customer = models.ForeignKey(Customer, null=True, on_delete=models.SET_NULL) def __str__(self): return self.customer.name class Order_Detail(models.Model): orderNumber = models.ForeignKey(Order, null=True, on_delete=models.SET_NULL) product = models.ForeignKey(Product, null=True, on_delete=models.SET_NULL) pounds = models.IntegerField(null=True) ounces = models.IntegerField(null=True) container = models.ForeignKey(Container, null=True, on_delete=models.SET_NULL) lot_code = models.CharField(max_length=200, null=True, blank=True) note = models.CharField(max_length=1000, null=True, blank=True) In my views.py, I'm playing with the following code: print('TEST2') o = Order.objects.all() o_notdelivered = Order.objects.exclude(status='Delivered') for e in o_notdelivered: print('Order ID:', e.id) order_detail_data = serializers.serialize("python", Order_Detail.objects.all().filter(orderNumber=e.id)) print('order_detail_data:', order_detail_data) With that code, I'm able to get the ORDER data and … -
What are the correct permissions and virtualhosts for running Django in a sub-directory?
I'm trying to install and run Django in a sub-directory, to keep it separate from a static html site in root, and am having issues with either file/folder permissions or virtualhosts. These two questions haven't helped and are very old: install django on subdirectory and Configure django on sub directory Is this file/folder permissions or virtualhosts issue? Why are the .py files not executing?

graphene-django: Determine Object type when multiple GraphQL object types use the same django model in node query
This is specifically for graphene-django (not just graphene) when performing a node(id: ...) {} query. Assume a fixed schema with 2 (or more) different GraphQL object types using graphene_django.DjangoObjectType linked to the same django model: import graphene_django from .models import Org as OrgModel class Org(graphene_django.DjangoObjectType): class Meta: model = OrgModel fields = ( "id", "name", "billing" ) class AnonymousOrg(graphene_django.DjangoObjectType): class Meta: model = OrgModel fields = ( "id", "name", ) Let's assume a query to Org of ID 7eca71ed-ff04-4473-9fd1-0a587705f885. btoa('Org:7eca71ed-ff04-4473-9fd1-0a587705f885') 'T3JnOjdlY2E3MWVkLWZmMDQtNDQ3My05ZmQxLTBhNTg3NzA1Zjg4NQ==' { node(id: "T3JnOjdlY2E3MWVkLWZmMDQtNDQ3My05ZmQxLTBhNTg3NzA1Zjg4NQ==") { id __typename ... on Org { id } } } Return: { "data": { "node": { "id": "QW5vbnltb3VzT3JnOjdlY2E3MWVkLWZmMDQtNDQ3My05ZmQxLTBhNTg3NzA1Zjg4NQ==", "__typename": "AnonymousOrg" } } } It returns the other object type 'AnonymousOrg:7eca71ed-ff04-4473-9fd1-0a587705f885', despite the relay ID specifying it was an Org object. Is there a way in graphene-django to "hint" or provide detail to assure the return type if what's specified in the ID and its fragment? Clarification on question Other questions were discussing graphene, not specifically graphene-django, which is doing the type determinations in this case. This is different from Django-graphene multiple types for the same model, as that one asked about how to handle field permissions and opened possibility to reconsidering schema structure (e.g. splitting … -
