Using Google Cloud SDK in Django Developement and UWSGI
I am trying to access Google Cloud Service in my backend process (views.py). I have successfully run this in developement server. Here is my views.py script : from google.cloud import bigquery @login_required def update_iphone(request): user_profile = UserProfile.objects.get(user=request.user) client = bigquery.Client() if request.method == 'POST': form = IphoneUpdateForm(request.POST) if form.is_valid(): sql = f""" query script """ client.query(sql) else: pass sql = f""" query script """ corporate_list = client.query(sql).to_dataframe() iphone_form = IphoneUpdateForm() return render(request, 'myapp/home.html', {'user_name':user_profile.first_name, 'corporate_list': corporate_list['corporate_name'].to_list(), 'form': iphone_form}) This views.py script runs well in development server. But if try to run it with UWSGI, I am getting error related to the google cloud as following : google.auth.exceptions.DefaultCredentialsError: Your default credentials were not found. To set up Application Default Credentials, see https://cloud.google.com/docs/authentication/external/set-up-adc for more information. My question is why am I getting this error if using UWSGI and not the development server ? how do I deal with this error ? Thank You -
Many one-to-one relationships pointing to the same model Django
I'm designing an application in Django where I have an Item model with numerous attributes for each item. I'm experiencing very poor performance in my application and I'm wondering if there are flaws in my setup that could be causing this issue. I am relatively new to Django, so any pointers would be greatly appreciated. Currently, I have around 200 attribute models, each with optional one-to-one fields linked to an item via a foreign key as follows: Attribute models: class AttrBase(models.Model): prev_value = models.CharField(max_length=250, null=True, blank=True) edited_by = models.ForeignKey( Account, on_delete=models.CASCADE, null=True, blank=True ) edited_on = models.DateTimeField(null=True, blank=True) options = None class Meta: abstract = True class ID(AttrBase): item = models.OneToOneField(Item, on_delete=models.CASCADE) value = models.CharField(max_length=250, null=True, blank=True) name = "ID" tooltip = "..." group = "..." class Height(AttrBase): item = models.OneToOneField(Item, on_delete=models.CASCADE) value = models.IntegerField(null=True, blank=True) name = "Height" tooltip = "..." group = "..." ...more I am also using a generic relationship to link to all of the groups, as follows: class AttributeGroup(models.Model): content_type = models.ForeignKey( ContentType, on_delete=models.CASCADE, limit_choices_to={"app_label": "attributes"}, ) name = models.CharField(max_length=250, null=True, blank=True) description = models.CharField( max_length=1000, default="TODO", null=True, blank=True ) def __str__(self): return str(self.content_type) def save(self, *args, **kwargs): self.name = self.content_type.name super(AttributeGroup, self).save(*args, **kwargs) This … -

How are connections handled by SQLAlchemy internally
Context Hello, I mostly use Django for my main backend monolith. In Django, you do not need to handle db connections on your own, this is abstracted (because Django uses the Active Record pattern instead of the Data mapper pattern used by Sqlalchemy). I have been doing some reading and I feel like I know the basics of the different constructs of Sqlalchemy (like engine, connection, and session). Nonetheless, we have started to scale our FastAPI + Sqlalchemy apps, but I have found this error appearing: sqlalchemy.exc.TimeoutError - anyio/streams/memory.py:92 - QueuePool limit of size 8 overflow 4 reached, connection timed out, timeout 10.00 I would like to understand why that is happening. Current setup Right now we have instances of the web server running, using the following command: python -m uvicorn somemodule.api.fast_api.main:app --host 0.0.0.0 As you can see, I'm not setting the workers flag, so uvicorn is only using 1 worker. On the SQLAlchemy engine, we are using the following options: SQLALCHEMY_ENGINE_OPTIONS = { "pool_pre_ping": True, "pool_size": 16, "max_overflow": 4, "pool_timeout": 10, "pool_recycle": 300, } engine = create_engine(get_db_url(), **SQLALCHEMY_ENGINE_OPTIONS) Questions Q1: does this apply to every worker of uvicorn? My guess is that if I spin two workers in uvicorn, … -
Using Django and reportlab to create a pdf. Report is failing when I try to include a field that is tied to a foreign key
My attempt at making a pdf fails with a server500 error when I attempt to export a field that is created by a foreign key. I believe this to somehow be the problem, as all other fields work as expected. This same field can be similarly exported as a csv. in views.py: def report_pdf(request): # Create a Bytestream buffer buf = io.BytesIO() # Create a canvas c = canvas.Canvas(buf, pagesize=letter, bottomup=0) # Create a text object textob = c.beginText() textob.setTextOrigin(inch, inch) textob.setFont("Helvetica", 14) # Designate the model customers = Customer.objects.all() lines =[] for customer in customers: lines.append(customer.address) lines.append(customer.address2) lines.append(customer.city) lines.append(customer.province3) # Loop for line in lines: textob.textLine(line) # Finsih up c.drawText(textob) c.showPage() c.save() buf.seek(0) return FileResponse(buf, as_attachment=True, filename='customer_list.pdf') and in models.py class Customer(models.Model): address = models.CharField(max_length=100, null=True, blank=True) address2 = models.CharField(max_length=100, null=True, blank=True) city = models.CharField(max_length=50, null=True, blank=True) province3 = models.ForeignKey(Province, null=True, blank=True, on_delete=models.PROTECT) and the foreign model: class Province(models.Model): province = models.CharField(max_length=2) def __str__(self): return(f"{self.province}") I've tried disabling the province3 field, at which point it works. Am I correct that it has to do with the fact that it uses a foreign key? If so, what may be the problem? I have checked the site logs and the apache … -

What is the correct way to query a many to many relationship in Django efficiently?
I probably haven't phrased this question correctly so apologies. Also probably why I cannot find much information when I google it. Anyway I have a Django project that I am using to create an API using Django Rest Framework. For this problem I have 2 models that are relevant. A Product model and an Offer model (slightly pseudocode so ignore any missing fields). class Offer(models.Model): image = models.ImageField(upload_to=upload_to, validators=(validate_image_file_extension,)) discount = models.IntegerField(validators=(MinValueValidator(0), MaxValueValidator(100))) start_date = models.DateField() expiration_date = models.DateField() products = models.ManyToManyField(Product, related_name='offers') customers = models.ManyToManyField(Customer) So as you can see in this model. There's a many to many link to the Product model. Inside the product model is just some standard stuff: class Product(models.Model): name = models.CharField(max_length=256) price = models.FloatField() stock = models.IntegerField() product_photo = models.ImageField(null=True, upload_to=product_photo_path, validators=[validate_image_file_extension]) Okay so now for the actual question. I am trying to add a new feature where it gets the discounted price for a product. If there is multiple offers, it needs to return the highest discount price. It also needs to take into account the customer who sends the request because the offers are not relevant for every customer. This needs to be done on the list endpoint from the API … -
How can I disable Chrome pop-ups like this while running automated Selenium tests in Python?
I am currently writing an automated testing suite for a large Django project for my corporation. Everything was going well until I updated Chrome (v.125.0.6422.142) and the Chromedriver (v.125.0.6422.141). When I ran the tests with the head, I saw that there was a Chrome Tip that popped up from the vertical ellipsis that opens the Chrome menu: Stupid message messing up my tests I checked with a custom GPT (using GPT-4) to see if this was causing potential issues, and had it confirmed (for what it's worth) that this popup indeed would be causing interference in my tests. However, I am unsure of how to get rid of it. I went through Stack OverFlow, GPT, and Github Copilot, and I implemented the following arguments to my setup: def setUpClass(cls): super().setUpClass() if os.environ.get('ENVIRONMENT') == 'LOCAL': # Retrieve the path from an environment variable chromedriver_path = os.environ.get('CHROMEDRIVER_PATH') if not chromedriver_path: raise ValueError("The CHROMEDRIVER_PATH environment variable must be set.") chrome_service = Service(executable_path=chromedriver_path) # Option to run in headless mode if os.environ.get('HEADLESS') == 'True': print("Running in headless mode.") chrome_options = Options() chrome_options.add_argument('--headless') chrome_options.add_argument('--enable-logging') cls.selenium = webdriver.Chrome(service=chrome_service, options=chrome_options) else: chrome_options = Options() chrome_options.add_argument('--disable-first-run-ui') chrome_options.add_argument('--no-first-run') chrome_options.add_argument('--disable-extensions') chrome_options.add_argument('--enable-logging') chrome_options.add_argument('--disable-popup-blocking') chrome_options.add_argument('--disable-notifications') chrome_options.add_argument('--disable-infobars') chrome_options.add_argument('--disable-blink-features=AutomationControlled') cls.selenium = webdriver.Chrome(service=chrome_service, options=chrome_options) cls.selenium.maximize_window() … -

change selinux policy to allow gunicorn access
How do I create a selinux policy to allow gunicorn to operate with nginx for a django managed web site? I know there's a way to do it, but don't understand selinux' arcane policy definitions --YES, I have read the documents. If I disable selinux with "setenforce 0", then "systemctl start gunicorn" loads gunicorn. If selinux is set to enforcing (setenforce 1), the systemctl command fails. This is definitely a policy issue. So, can anyone describe how to set the policy to allow gunicorn to load? Thanks, Joe White -
Why 'coverage' considers all of my class-based-views as tested?
I'm just learning django testing. When I use 'Coverage' module to check which parts of my code is tested, it considers almost all of class-based-views as tested while I have commented out all of my tests. I investigated this problem and found that in urls.py I have this line: from . import views It seems importing views.py file or just a class from views.py make all classes in views.py run once e.g. the print line in this code will be executed: class AuthorDelete(PermissionRequiredMixin, DeleteView): model = Author success_url = reverse_lazy('authors') permission_required = 'catalog.delete_author' print("----- AuthorDelete -------") And 'Coverage' will mark them as tested. But obviously this class is not tested at all. How can I get real and exact test coverage report? Should I use other tools rather than 'Coverage'? Thanks in advance -

Tips for Django Optimization
i'm looking for tips on things to check next in order to increase the efficiency of my django in production. The loading times vary wildly; sometimes the page are loaded in 200ms, sometimes they require multiple seconds. I've worked extensively on SQL and cache; see the attached image, they take a combined 25ms. Yet the page required almost 10 seconds to load. As techical information, I'm using postgresql (CONN_AGE set to 6), nginx (12 workers on 6 processors), and django-redis-cache. What can I look for next? I've tried to work extensively on SQL and cache, in order to see a consistent reduction on loading times, yet in some occasions the page require multiple seconds to load. -
Java Script for insert html does not work
I load posts when scrolling the page, and for some reason the script for opening a photo of a post or liking a post does not work, I thought for a long time why this was, but I still don’t understand. views.py For the start page (posts that are loaded immediately, and not by scrolling the page), everything is ok. posts.html And if it helps, here's a piece of the script that doesn't work (all of it doesn't work): posts_script.js I checked a lot of things, it seems like all the classes are needed, the data of tags are also normal, that is, everything is there for the script to work, but for some reason it doesn’t want to work, I would be very grateful if you help me. -
How to create a generic relationship without adding dependency between apps in Django?
I have an ecommerce store app that have those apps: core: specific for the ecommerce store app needs. likes: independent reusable app that is supposed to be used with different models from other apps. store: independent reusable app that has the models and views for the ecommerce app. Now I want to add the ability for the user to like a product, so I want to add a like (from likes) to the product (from store), how can I do it without adding explicit dependency (import likes in store) between the two apps?

Yet another BS error from the lovely Django: django.db.utils.IntegrityError: NOT NULL constraint failed
Right, just because I just simply love having my time wasted by Django's silly temper tantrums (because it clearly identifies as a spoiled little five-year-old child and not a framework that just does what the programmer tells it to do), is there any particular valid reason as to why, once again, Django is throwing an "exception" (it's adorable you call it an "exception", i feel "tempter tantrum" would be more of an apt name - I may put that to the Django team as an idea for their next release) of: django.db.utils.TEMPERTANTRUM: NOT NULL constraint failed When this is my model #model.py from django.db import models import uuid # Create your models here. class ServiceDegradations(models.Model): issue_reference = models.UUIDField(primary_key=True, default=uuid.uuid1, editable=False) issue_title = models.CharField(max_length=50) issue_description = models.TextField() issue_date = models.DateTimeField(auto_now=True) class Meta: verbose_name_plural = "Service Degradation's" def __str__(self): return self.issue_title Isn't my life just fantastic, surrounded on a daily basis by stupidity and pointlessness.

Django show sqlite data on html site
I'm about to write code for a new web program with Django. So the problem is that I want to have the data from the database (db.sqlite3) on the HTML page and that works fine but only if I add an item, otherwise the data is not shown. I would be really glad if someone can help me. Thanks!

Prevent django from writing e-mail information to stdout
I'm using django 2.2. with python 3.6. In some cases my server stores stdout into a log used by managers. For some reason django started to write to stdout at send-mail some time ago. The managers do not like it because it looks like en error case for them. So the following sends the e-mail, but also writes to stdout: ^C(venv) > python manage.py shell Python 3.6.15 (default, Sep 15 2021, 12:00:00) Type 'copyright', 'credits' or 'license' for more information IPython 7.5.0 -- An enhanced Interactive Python. Type '?' for help.
