How to enrich page navigator by adding field from first and last objects in Django paginator?
I am building a Django app form managing the digitalisation process of analog film rolls. I would like to add the film_roll.from_year field of the FilmRoll model to my page navigation widget in a Django template. This greatly facilitates navigating to the right page by looking at the year_from range below each page. My view is defined as follows: def index(request): film_roll_list = FilmRoll.objects.order_by( "from_year", "from_month", "title" ).annotate( scan_count=Count("myScanned_VS_NLP", distinct=True), ) paginator = Paginator(film_roll_list, 20) page_number = request.GET.get("page") try: page_obj = paginator.get_page(page_number) except PageNotAnInteger: # If the page parameter is not an integer, show the first page page_obj = paginator.get_page(1) except EmptyPage: # If the page is out of range, show the last page page_obj = paginator.page(paginator.num_pages) film_roll_count = paginator.count context = { "film_roll_list": film_roll_list, "page_obj": page_obj, "film_roll_count": film_roll_count, } return render(request, "filmrolls/index.html", context) Here's the page navigator code in the template: {# Page navigator: start #} {% if page_obj.has_other_pages %} <div class="row"> <div class="btn-group" role="group" aria-label="Item pagination"> {% if page_obj.has_previous %} <a href="?page={{ page_obj.previous_page_number }}" class="btn btn-outline-primary">&laquo;</a> {% endif %} {% for page_number in page_obj.paginator.page_range %} {% if page_obj.number == page_number %} <button class="btn btn-outline-primary active"> <span>{{ page_number }} <span class="sr-only"></span></span> # TODO - add 'year_from' range for the … -
Django session in tests
everyone! I can't figure out how the sessions work in Django. I have a shop, an anonymous user's shopping cart is bound to session_key. The session key is taken from the request object. def _check_session(self, request) -> int | str: session_key = getattr(request.session, ‘session_key’, None) if session_key: return session_key else: request.session.create() return request.session.session_key I'm writing tests, one test adds items to the basket, I take the anonymous user client and make a post request to add, everything is ok. Then in the second test, I take the same anonymous client, make a get request to get the contents of the basket. But in this request the request object has no session_key. Why in the second test, the request object does not contain a session_key? The client is the same. These two tests are written within one TestCase. -
Django constraints: unique together and accept one and only one value
I'm trying to implement a constraint for the following model: class Consumption(models.Model): simcard = models.ForeignKey(SimCard, on_delete=models.CASCADE) start_date = models.DateTimeField() duration_billed = models.FloatField(null=True) volume_billed = models.FloatField(null=True) sms_billed = models.FloatField(null=True) I would like to constraint the user to save one and only one value for duration_billed, volume_billed, sms_billed for a given simcard and start_date. I have the following Meta class: class Meta: constraints = [ UniqueConstraint( fields=['simcard', 'start_date', 'duration_billed'], name='unique_simcard_and_start_date_and_duration_billed' ), UniqueConstraint( fields=['simcard', 'start_date', 'volume_billed'], name='unique_simcard_and_start_date_and_volume_billed' ), UniqueConstraint( fields=['simcard', 'start_date', 'sms_billed'], name='unique_simcard_and_start_date_and_sms_billed' ), ] The problem I face with my constraints in that the DB accept several duration_billed, volume_billed, sms_billed for a given simcard and start_date. The result I try to achieve is if a duration_billed exists for a given simcard and start_date, the user should not be able to import a new duration_billed (even if the value is different from the one stored in DB) for the same simcard and start_date. Same goal for volume_billed and sms_billed. I hope my issue is clear. Any help or advice would be much appreciated 🙏 Many thanks in advance -
“OperationalError: Could not translate host name “db” to address in Dockerized Django App with Datadog”
I have a very complex django project that uses postgresql as database, where I have setup datadog to send traces and events. It works fine locally and I am receiving traces and events in datadog.

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

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?
