The current path, tags/linux/, didn't match any of these
Django 3.0.8 urlpatterns = [ path('tags/slug:tag', PostListView.as_view(), name="tags"), ] I load: http://localhost:8000/tags/linux/ Problem Page not found (404) Request Method: GET Request URL: http://localhost:8000/tags/linux/ Using the URLconf defined in pcask.urls, Django tried these URL patterns, in this order: tags/<slug:tag> [name='tags'] __debug__/ ^media/(?P<path>.*)$ ^static/(?P<path>.*)$ ^static/(?P<path>.*)$ The current path, tags/linux/, didn't match any of these. Could you help me understand why this url didn match? And how to cope with this? -
Wagtail Pages from Django Model/AdminModel
I can't seem to find any info on this, everything points to adding models to admin. I don't need that. What I am trying to do is probably pretty simple. I have a django model AdminModel called Location. I have 23 locations plugged into the model. I would like a page for each location, with data from the model used to populate each page, and a listing page. The locations make individual use of an inventory API and google places API. The keys are stored per location in the model, so if I can just get the pages stood up on my URL I have enough to populate them. If it is possible, I would like to generate them as wagtail pages, so I can make use of some fields for content not stored in the model per location page. I'd be happy if I could just get the pages generated from the model data though. I'll take a search term or a doc link. Like I said, my search terms are only finding AdminModel instructions. Any help is appreciated. -

How can i use custom model permissions to check before displaying a viewset?
I'm quite new to Django rest framework and are struggling to use the custom model permissions to check if a user is allowed to access a certain endpoint.

Processing abandoned The video could not be processed - Youtube API?
I am uploading mp4 videos through my website using youtube data v3 api and the http post request looks like: access_token = request.session['access_token'] url = "https://www.googleapis.com/upload/youtube/v3/videos?part=snippet" payload = { 'snippet':{ "categoryId": "22", "description": "Description of uploaded video.", "title": "Test video upload." } } files = [ ('media_body', request.FILES['media_body']) ] headers = { 'Content-Type': 'video/mp4', 'Authorization': 'Bearer '+access_token, } response = requests.request("POST", url, headers=headers, data=payload, files=files) print(response.text.encode('utf8')) context = { 'r': response } return render_to_response('dashboard/manage_content/youtube.html', context) And this is the response I get: { "kind": "youtube#video", "etag": "yS7DhsHOhsDM-vXZiGUmLXcKST0", "id": "dII224dYC2o", "snippet": { "publishedAt": "2020-07-03T12:11:43Z", "channelId": "UCmv2Sec30iBc13b7ntf93Ow", "title": "unknown", "description": "", "thumbnails": { "default": { "url": "https://i.ytimg.com/vi/dII224dYC2o/default.jpg", "width": 120, "height": 90 }, "medium": { "url": "https://i.ytimg.com/vi/dII224dYC2o/mqdefault.jpg", "width": 320, "height": 180 }, "high": { "url": "https://i.ytimg.com/vi/dII224dYC2o/hqdefault.jpg", "width": 480, "height": 360 } }, "channelTitle": "Nikhil Dhoot", "categoryId": "20", "liveBroadcastContent": "none", "localized": { "title": "unknown", "description": "" } } } But on the videos tab, I get the error: Processing abandoned The video could not be processed. The fact that the video responds a success message means that all the authentication process before it has been successful. However, if required I can edit and share that code too. -

Render a django-simple-history query in a django-tables2 table
I try to render a django-simple-history queryset in a django-tables2 table. At the moment I pass the raw queryset to the template inside the context. Further I want to pass the Queryset to a Table object to use the features of the table like linkyfy columns or exclude columns. For this I have to specify a model inside the tables meta. The problem here is, that the model for the history is generated automatically. Actually code: #views.py from .tables import HistoryTable class HistoryView(LoginRequiredMixin, SingleTableView): template_name = "funkwerkstatt/history.html" def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) context["table"] = Device.history.filter(id=self.kwargs["pk"]) ## futur code #context["table"] = HistoryTable(Device.history.filter(id=self.kwargs["pk"])) return context #tables.py import django_tables2 as tables class HistoryTable(tables.Table): device = tables.Column(accessor="device", linkify=True) class Meta: model = # HistoryModel?! empty_text = "No entry" exclude = ["id",] Is there a way to referent the auto generated HistoryModel -

Mypy complains about TestCase attributes set in setUpTestCase
I have a project written in Django (Django 3.0, Python 3.8), using django-stubs to handle type annotations. Everything went fine until I wrote some tests: from django.test import TestCase class TestSomething(TestCase): @classmethod def setUpTestData(cls): cls.some_value = 'foo' cls.another_value = 'bar' def test_me(self): self.assertNotEqual(self.some_value, self.another_value) When I run mypy, it raises '[attr-defined]' errors about the TestCase class attributes defined in setUpTestData: $ mypy --show-error-codes . my_app/tests/test_something.py:6: error: "Type[TestSomething]" has no attribute "some_value" [attr-defined] my_app/tests/test_something.py:7: error: "Type[TestSomething]" has no attribute "another_value" [attr-defined] my_app/tests/test_something.py:10: error: error: "TestSomething" has no attribute "some_value" [attr-defined] my_app/tests/test_something.py:10: error: error: "TestSomething" has no attribute "another_value" [attr-defined] I cannot find any advice about type annotations in tests (even tests in general, not to mention Django or unittest tests specifically). I don't think I am using setUpTestData to do anything it is not supposed to do, so I wonder why nobody reported such issues before. My main question is: How can I annotate this code to make mypy satisfied? A corollary question: Does it even make sense to add type annotations in tests? Maybe I should just configure mypy to ignore test modules? Here's the mypy.ini file - I would rather not change the settings to be more lenient: [mypy] … -
How do I run tasks in the background using Django?
I have an end-point in Django which initiates a function which takes really long to complete. I don't want the request to wait until this function has been completed. def MyRequest(APIView): def get(self, request, *args **kwargs): a_functio_which_takes_really_long_time() return Response({"message" : "We're Working on it."}) I tried using asyncio with Django Asynchronous Support. Also tried python threading here. But all these are making the request to wait until the function is completed. I know that we can easily achieve this using Celery. But that approach would require me to use a message-broker such as Redis, RabbitMQ or any other similar servers which I'm not supposed to use. -

django-private-chat implementation
I'm trying to integrate a private chat feature i.e any registered user can chat with another registered user, in my web application. I'm using Vue.js on front end and django backend. I'm still new to websockects, channels etc. After a bit of searching I found django-private-chat package, but the documentation does not contain much information. I'm not able to wrap my head around on the implementation of this package with a web framework like Vue. I'm also using django rest framework. -

wrong font in url query?
Cannot find information. I do queries to some web site..., but api_key seems in the wrong font format. I tried to use simple form: base_url = 'https://somesite.ru/' coding = urlencode({'api_key':entry_code}) actual = str('...&api_key={}'.format(..., coding)) url = '{}?{}'.format(base_url, actual) I tried to use a little more complicated approach: ... coding = urlencode({'api_key':entry_code}) ... I tried to urlencode whole phrase: actual = urlencode('...&api_key={}'.format(..., coding)) When I url encode whole phrase, on the place of spaces instead of & symbol it gives me %20 symbol and host responds that xml does not support this format. When I do urlencode only api_key or do simple str query, the host tells me that it cannot recognize api_key, and shows following: Wrong api_key (ЕЖЕВРРљРђ not found in database)... The site is on the Russian web (.ru), so as I understand api_key has to be in cyrrilic, I understand my font in code is in UTF-8... What to do here? How can I change my api_key to cyrillic? -

getting the full path of an url from django (not django template)
I'm a bit lost on getting the full path of an url from django. From questions such as this one i should be able to get the path using get_current_site, but it seems it is not supported anymore. In specificts I have the following urls.py: app_name = "core" urlpatterns = [ path("<str:model_string>/", tables_views.table_from_model, name="table_from_model"), With django template it would be easy to acces it: {% url 'core:table_from_model' mymodel %} However i need to acces from a python script. I can of course just write something like: http://127.0.0.1:8001/alert/ but then, the moment I go live, this method would fail (the url would not anymore be 127...). Is that solvable? Thanks -

Heroku Django - Random connection issues to database
We have a Django app which is launching soon and we have been testing for weeks, an issue has arisen today randomly where the application throws an exception connecting to our AWS RDS MySQL instance. This has happened 4 times, and I can't reproduce - it seems random. OperationalError at /api/ourcall/ (2005, "Unknown MySQL server host 'ourdb.ffg4565ihqjpg1.eu-west-2.rds.amazonaws.com' (11)") I changed the server host above, but the error is that. The only change we made yesterday was to scale from 3 Dyno's to 5. I don't know if that is related or if it is a DNS/networking issue? I have contacted Heroku support but haven't heard back yet. Any help would be really appreciated -
Attempting to change pages without full reloading in django and javascript
I have tried to do something with django and javascript. So for example if I want to go to my "about" page from my "home" page, I only want to load the contents of the page. There are many similar elements in both pages (such as a header image and navbar) that does not need to be reloaded.

Make website deployment as efficient as possible coming from django
I recently got obsessed with optimizing a website of ours for speed and resource efficiency. The site in question is currently developed in python django. I've came across https://github.com/the-benchmarker/web-frameworks, which lists django as a rather inefficient framework. Hence my question: Is it worth it to rewrite the site into an API in a faster language (say top 1: nim, httpbeast) and then just use vue.js to offload the rendering to the client? The site is getting a lot of traction and we need to save on servers. -
Do some operation in a django serializer?
I have created a serializer, which will just call some util functions, without doing anything else.

Or should I call it in the view itself? -
Djongo search error string with parentheses
I'm working on a website using Django template and MongoDB. I implemented a search but some items have parentheses in their fields. When I use contains or icontains function to search in the database, it throw me an error or doesnt find the item. For example, if I search "Test (test" it will throw a regular expression missing error. If I search "Test (test)" It won't find anything I manage to find that parentheses are not considered as string for mongo. I tried to escape parentheses with //( and //) but it doesn't work. I don't know what I can do. Thanks for your help
