Django custom template tag that does not require a quoted string (like `load`)
The django template tag {% load mylib1 mylib2 %} does not require mylib2 and mylib1 to be quoted as a string. How does one create a template tag like this? All the examples in the documentation one has to quote argument strings. I tried to find the code for the load tag in django/template/loader_tags.py and django/template/templatetags, and grepped for @register.tag("load") but could not find it. -

How to call a view from within itself in a Django REST API?
I have this function in my Django REST API that handles the insertion of products. Sometimes a product will be a variational product (when product.type = 3), in which case I get all the permutations of these variations and want to insert a new product corresponding to each permutation into the database. @api_view(['POST']) def upsertProduct(request): productData = request.data['product'] variations = productData.pop('variations', []) variationTypes = productData.pop('variationTypes', []) product, created = Product.objects.update_or_create(pk=productData['id'], defaults=productData) if (productData['type'].id == 3): variations_by_type = [] for variationType in variationTypes: variations_by_type.append([variation for variation in variations if variation['variationType'] == variationType['id']]) combinations = list(itertools.product(*variations_by_type)) for combination in combinations: productData['name'] = product.name + ' (' + ' | '.join(' : '.join(i['name'] for i in item) for item in combination) + ')' productData['type'] = {'id': 5} productData['parent'] = product.id #Recursive call should go here #upsertProduct(request={'data': {'product': productData}}) My first attempt was to simply call the function as I did in the commented line. Django returned the following AssertionError: The request argument must be an instance of django.http.HttpRequest, not builtins.dict. I then attempted making use of this HttpRequest object from Django, but can not figure out how to use it properly for this use case. I've also tried the standard request library in … -

Get scrapy spider response back on django Rest api GET
I'm working project it contains a GET request with a few parameters suchas (airline code and flight date), I pass those parameters to a crawler coded using scrapy . I've created Django command in management/commands to hit the scrapy crawler and as soon the scraping is done the data being saved in particular models. As I want to return that saved data to the same GET request, I have a few questions regarding it. How to return data in GET request? As I couldn't find a way to get returned data from scrapy crawler. How do I make wait that GET request for a particular time when scraping is being done. Assuming GET request is on waiting and scrapping is done now I have to validate if there is scraped data present in database accordingly to the params. Assuming the data is found in database and then how can I return it to the same GET request? If I want to use celery in this whole process what could be the best use of it? -
How to secure a spyne web service with Basic authentication in django
I have a soap service in django application and I covered this service with login required decorator. Client should send soap request with Authorization(Basic) headers and with these credentials I have to authenticate this client. I found one example for http headers in spyne: class RequestHeader(ComplexModel): __tns__ = 'spyne.examples.authentication' username = unicode() ee = unicode() class UserService(ServiceBase): __tns__ = 'spyne.examples.authentication' __in_header__ = RequestHeader @rpc(Mandatory.String, _returns=String) def get_head(ctx, user_name): print '*'*20 print ctx.in_header_doc print ctx.in_body_doc print ctx.in_header.ee retval = "Where's the header" return retval But I thought it did not match with my requirements Because client should authenticate with given credentials from me.

How to apply advance django query set filters based on two different columns?
I am new to django. I am working on a test project. Where I have a Model CollectFee with structure given below: Database table screenshot I want to apply a query set in the views which will display all the records where feetype_id is not 2, when this record is excluded then also exclude those records which have the same boarder_id as of already excluded record. For example, Exclude the second row as it has feetype_id = 2 then also exclude the third row because it has the same boarder_id as of second row. As I am new, I was able to just implement the filter below: def feedue(request): fee_type = 2 duefee= CollectFee.objects.exclude(feetype_id=2) context = {'duefee':duefee} return render(request, 'fee-due.html', context) -

Webhook from Django 4.1 to python-telegram-bot 20.0a2
I use the python-telegram-bot 20.0a2 library and Django 4.1 The bot runs by main.py script: if __name__ == "__main__": asyncio.run(main()) Inside of the main script I also run uvicorn in the same ascynhronous context as Application instance # Run application and webserver together async with application_tg: await application_tg.start() await server.serve() # uvicorn await application_tg.stop() What is the problem? I use webhook for my bot Django's url.py calls async view but the view can't get initalized Application instance of the bot. so the question is: How can to rearrange a scheme of interaction between python-telegram-bot 20 and Django 4.1 in a way that I can access Application instance from a Django hook? Addition: It's easy to achieve by using other frameworks such as starlette as it mentioned on the official wiki page of PTB library: https://docs.python-telegram-bot.org/en/v20.0a2/examples.customwebhookbot.html My main script: https://gist.github.com/SergSm/6843fadf505b826f83a10bf7eebc3fa0 my view: import json from django.views import View from django.http import JsonResponse, HttpResponse from django.views.decorators.csrf import csrf_exempt from telegram import Update from bot.tgbot.main import application_tg async def telegram_handle(request): if request.method == 'POST': await application_tg.update_queue.put( Update.de_json(data=json.loads(request.body), bot=application_tg.bot) ) return JsonResponse({"ok": "POST processed"}) else: return JsonResponse({"ok": "GET processed"}) -

local variable 'user' referenced before assignment error in django function
I have this function in django that adds a new item to the wishlist, the function is doing what it should do but when I add a new user that was not registered, when adding an item to the wish list it returns this error, but when i refresh the page the error no longer exist. I think the problem is that when a new user registers, he still does not have the database created in the wishlist model, so the try: condition fails because the user does not yet exist in the model, passing the except: condition where the user database is created, but I have to manually refresh the page so that the page no longer shows me the error. How can I fix this so that the page no longer shows me this error? def add_or_remove(request, listing_id): if request.method == "POST": if (request.POST["action"]) == "add": try: user = Wishlist.objects.get(user=request.user) listing = Listing.objects.get(pk=listing_id) user.item.add(listing) except: create = Wishlist( user=request.user, ) create.save() user.item.add(listing) messages.success(request, 'you added to Wishlist') elif (request.POST["action"]) == "remove": user = Wishlist.objects.get(user=request.user) item = user.item.get(id=listing_id) user.item.remove(item) messages.success(request, 'you removed from Wishlist') return redirect(reverse("listing", args=[listing_id])) -
Best way to incorporate a "utils" module in a django project?
I'm creating a project that will have several app named after states, such as: |-my_state_project |---my_state_project |---new_jersey |---alabama |---rhode_island I want to create a utils module that each app can import from. The utils.py file inside the utils module will have functions used to scrape data from the web using bs4. Each app will have a jobs.py script to import from utils.py. So the project will look like: |-my_state_project |---my_state_project |---new_jersey |------jobs.py |---alabama |------jobs.py |---rhode_island |---utils |------utils.py My questions are: Is this how Django projects are usually structured? I'm getting a ModuleNotFoundError: No module named 'utils.py' while trying to import inside one of the jobs.py files. I'm importing it using from utils import utils. Why is it complaining? This should be rudimentary The alternative would be to create a utils.py file inside each app which doesn't seem very pythonic (especially since the utils.py file may grow and updating each file individually would be torture :) -
NGINX throughs 404 and wont load static
Hopefully, Y'all can help me with this one and hopefully I am in the right areas to post this. Just recently began learning Django and I am trying to get it deployed to Linux. I have been using gunicorn and nginx for this deployment and for the most part I have been successful. I am able to successfully deploy and interact with my app, navigate pages and interact with some of the post requests. The only thing I have been banging my head around trying to figure out what is going on with my static files. All of my css and images do not display currently and I have tried searching everywhere for the resolution. I have tried using an alias in the nginx file and I have made sure that my static root and URL is fine, nothing i have tried has done the trick. the weird this is, when looking at the access logs from nginx it shows the Get request going to the correct file and path, but shows 404? I am at a loss here lol! What is really weird is that the static folder contains a few csv's that are processed and served by a … -

Django Rest Framework invalid serializer data, can not figure out why
I am creating a simple model with a many-to-many field. The model works fine and I can create model through the admin panel, and I can make a get request to see that model (except that it only returns user IDs instead of the user models/objects). My problem is when creating a post request to create said model. I get one of the two errors depending on the changes I make, The serializer field might be named incorrectly and not match any attribute or key on the 'str' instance. or AssertionError: You cannot call '.save()' on a serializer with invalid data., either way it has something to do with my serializer.

Negative impact of a Django model with multiple fields (75+ fields)
I'm in the process of building a web app that takes user input and stores it for retrieval and data manipulation. There are essentially 100-200 static fields that the user needs to input to create the Company model. I see how I could break the Company model into multiple 1-to-1 Django models that map back the a Company such as: Company General List item Company Notes Company Finacials Company Scores But why would I not create a single Company model with 200 fields? Are there noticeable performance tradeoffs when trying to load a Query Set?
