Can Django fixtures be used for production?
I have a Django application that reads different CSV files and saves them to the same model/table in the DB. While fixtures are certainly used for setting up a test environment quickly, I used the fixture to configure the different CSV Schemata that is subsequently parsed by the Django application. So each of the data provider has their own distinct schema which is a different row in the CsvSchema table. During code review it came up that this is bad style because -- It leads to duplication of data. I found it useful to pass such configurations via a fixture and treated it like a configuration file. To further treat the fixture like a configuration file, I even put it inside the git repository, which is again somethong the reviewer agrees with. The reviewer also claimed that fixtures should be use only once in the lifetime of the application, while setting it up initially. To me, the fixtures are just a tool that Django provides us. I can play around with the schema details in my development machine, and then dump them into a fixture, effectively using it as configuration. Am I playing too hard and fast with the rules … -

I am trying to add an active class to my nav bar items on my website when clicked
I want to add the active class to the navbar item that I click on, on my website. In my JS code, it tells the program what class to look under ("nav-item"). Then it tells my program to remove the active class from the current active class, and then add the active class to the class that was clicked. I'm assuming the logic is correct but I most likely missed syntax. I am new to HTML and JS so any help would be greatly appreciated. HTML Code: <ul class="navbar-nav"> <li class="nav-item"><a class="nav-link js-scroll-trigger active" href="#about">About</a></li> <li class="nav-item"><a class="nav-link js-scroll-trigger" href="#education">Education</a></li> <li class="nav-item"><a class="nav-link js-scroll-trigger" href="#experience">Experience</a></li> <li class="nav-item"><a class="nav-link js-scroll-trigger" href="#skills">Skills</a></li> </ul> JS code: $('.nav-item').on('click', '.nav-link js-scroll-trigger', function () { $('.nav-link js-scroll-trigger active').removeClass('active'); $(this).addClass('active'); }); -

Django-autocomplete-light - "No results found" in browser on startup - after doing one search in admin - results are found in browser again
I have a peculiar problem with Django-autocomplete-light. When I go to my browser and try searching for something I get "no results found" - but when I go to the admin panel and add a model, the results pop up as they should. When I have done this one time, I can go back to the browser and then the results show up as they should. I'm suspecting some caching issue, but not sure how to debug this.

Django rest_framework MVC structure
I'm currently working on a Django project, using the rest_framework. The project is built around API endpoints the client-side will use to send/retrieve data about features such as users, players, playerInventory etc etc. My question is, I'm struggling to structure this project and I'm not sure if i should be destructuring the data my front-side receives. The data I'm working with looks like API ENDPOINT Returns a single player inventory [GET] { "elementId": 1, "elements": [1, 2, 3 ,4] } API ENDPOINT Update a single player inventory [POST] from -> { "elementId": 1, "elements": [1, 2, 3 ,4] } (example) to -> { "elementId": 1, "elements": [3, 3, 3 ,1] } I'd like to be able to use a front-end 'model' concenpt that takes the data from my API fetches and constructs them for me so i can use that data in a better manor. Could someone give me a detailed Django project file structure and some Javascript model code design patterns possible? here's my models.py: class User(models.Model): userId = models.AutoField(primary_key=True) username = models.CharField(max_length=16) email = models.EmailField(max_length=30) isMember = models.BooleanField(default=False) class meta: db_table = 'app_users' app_label = "app" managed = True def __str__(self): return str(self.userId) class Player(models.Model): playerId = models.ForeignKey(User, … -

How do I set up a nested URL pattern for /category/subcategory/post in Django?
I've looked through several answers and I cannot seem to figure out how to do this. My best guess is this has something to do with all of these answers are specific to writing function based views. The problem: I have a portal where I want the URL structure to be: /portal/engagement/engagement_name/finding/finding_name So I've tried several things and this is the closest I can get: urlpatterns = [ path('', login_required(CustomerDashboard.as_view()), name='portal_dashboard'), path('engagement/add', login_required(EngagementCreateView.as_view()), name='engagement_create'), path('engagement/<slug:slug>/', login_required(EngagementDetailView.as_view()), name='engagement_detail'), path('engagement/<slug:slug>/edit', login_required(EngagementUpdateView.as_view()), name='engagement_update'), path('engagement/<slug:slug>/finding/add', login_required(FindingCreateView.as_view()), name='finding_create'), path('finding/<slug:slug>', login_required(FindingDetailView.as_view()), name='finding_detail'), path('finding/<slug:slug>/edit', login_required(FindingUpdateView.as_view()), name='finding_update'), ] If I try to do something like engagement/<slug:slug>/finding/<slug:slug>/ it just errors. I've tried to follow some answers like choosing the slug field (i.e. slug:engagement_slug``` but none of it works. I'm using class based views. My models are: Company Engagement (FK to Company) Finding (FK to Engagement) I'm not sure what other code I can provide to help. I've read some other options on overriding the get_object method and passing the slug as a **kwarg. I'm just not sure what is the "right" way to do this. -

Django - Given time zone, month and year get all post created on that date in that time zone
So I have this Post model. I want to be able to retrieve all posts that were created in a month, year under a certain time zone. model.py class Post(models.Model): uuid = models.UUIDField(primary_key=True) created = models.DateTimeField('Created at', auto_now_add=True) updated_at = models.DateTimeField('Last updated at', auto_now=True, blank=True, null=True) creator = models.ForeignKey( User, on_delete=models.CASCADE, related_name="post_creator") body = models.CharField(max_length=POST_MAX_LEN) So for example if a user creates 10 posts in November, 2 in December of 2021 in PST.

Multiple concurrent requests in Django async views
From version 3.1 Django supports async views. I have a Django app running on uvicorn. I'm trying to write an async view, which can handle multiple requests to itself concurrently, but have no success. Common examples, I've seen, include making multiple slow I/O operations from inside the view: async def slow_io(n, result): await asyncio.sleep(n) return result async def my_view(request, *args, **kwargs): task_1 = asyncio.create_task(slow_io(3, 'Hello')) task_2 = asyncio.create_task(slow_io(5, 'World')) result = await task_1 + await task_2 return HttpResponse(result) This will yield us "HelloWorld" after 5 seconds instead of 8 because requests are run concurently. What I want - is to handle multiple requests to my_view concurrently. async def slow_io(n, result): await asyncio.sleep(n) return result async def my_view(request, *args, **kwargs): result = await slow_io(5, 'result') return HttpResponse(result) I expect this code to handle 2 simultaneous requests in 5 seconds, but it happens in 10. What am I missing? Is it possible in Django? -
Django background task like FastAPI
I have a requirement that I need to calculate hash of some images in background after the data inserted on DB tables. I saw FastAPI Vs Django implementation of background task and it seems very easy and feasible solution for background task implementation in FastAPI comparing to Django. So I need to know is there similar kind of implementation on Django available or not? because it's seems too much on Django for a simple background task. OR It would be better to use simple multiprocessing.Process For Django: I need to do these steps for achieve background task Installation I like [pipenv][1] so: > cd [my-django-project root directory] > pipenv install django-background-tasks Now add 'background_task' to INSTALLED_APPS in settings.py: INSTALLED_APPS = ( # ...

what is the correct way to filter data from db in monthly and yearly basis for analytics?
I am making an analytics section for my client, where I need to display data in graphical form. For this I am using chart js. Now I have a model to store visitors of the website. Now I want to filter the data in monthly and yearly basis to put it in chart js and display it graphically. Now what I am doing is this monthly_visitor = VisitorCount.objects.all().filter(date_of_record__month = today.month).count() yearly_visitor = VisitorCount.objects.all().filter(date_of_record__year = today.year).count() Here, I am able to get the count for my current month and year. But making variables for each month and year is not the right to do it. So please suggest me what is the correct procedure to filter the data so that I can make the analytics. I have never before done this, so I do no the correct approach, please suggest me. Also the chart js code looks like this, which also perhaps no the correct way to do make the analytics const vismonth = document.getElementById('visitorMonthly').getContext('2d'); const visitorMonthly = new Chart(vismonth, { type: 'bar', data: { labels: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'], datasets: [{ label: 'Visitors Monthly', data: [12, 19, 3, 5, 2, 3], backgroundColor: … -

My settings.py (the most important settings for this): INSTALLED_APPS = [ "django.contrib.admin", "django.contrib.auth", "django.contrib.contenttypes", "django.contrib.sessions", "django.contrib.messages", "django.contrib.staticfiles", "cv", ] STATIC_URL = "/static/" BASE_DIR = os.path.dirname(os.path.abspath(__file__)) STATIC_ROOT = os.path.join(BASE_DIR, "cv/static") In my view I use the static() function to retrieve the static file def index(request): file_path = static("configuration/configuration.json") with open(file_path) as f: configuration = json.loads(f.read()) return render(request, "index.html", configuration) But when It keeps giving me the error: No such file or directory: '/static/configuration/configuration.json' I can fix it by explicitly parsing the path string to the index function: "./cv/static/configuration/configuration.json" But how do I do it with the static() function? The static() function uses the static_url variable, but no matter how I adjust it, it keeps giving me a similar error. Anyone an idea what I'm doing wrong here? -
Integration Pycharm, Docker Compose and Django Debbuger getting error: /usr/local/bin/python: can't find '__main__' module. in ''
I'm having a problem using Pycharm to run a Docker container to debug a Django project on MacOs. The Pycharm setup is working fine to run the Django project inside a Docker container. But when I try to do a debugger I'm having the following issue: /usr/local/bin/docker-compose -f /Users/claudius/Studies/Pycharm/test-api/docker-compose.yaml -f /Users/claudius/Library/Caches/JetBrains/PyCharm2021.2/tmp/docker-compose.override.1494.yml up --exit-code-from web --abort-on-container-exit web Docker Compose is now in the Docker CLI, try `docker compose up` mongo is up-to-date postgres is up-to-date Recreating test-api_web_1 ... Attaching to test-api_web_1 Connected to pydev debugger (build 212.4746.96) web_1 | /usr/local/bin/python: can't find '__main__' module in '' test-api_web_1 exited with code 1 Aborting on container exit... ERROR: 1 Process finished with exit code 1 To set up the Pycharm I did: Add a Python interpreter with docker-compose and the container of the web application (Django). Add a Django config for the project. Add a Run/Debugger config. Does someone have any suggestions?
