Django app cannot delete AWS S3 bucket items
DISCLAIMER: (I'll put it at the top so people don't just skip and not read) I just recently started using AWS so I still don't understand a lot of things and yes, I already did the research on this subject and every post I found said to "make the bucket publicly available" which is something I would like to avoid and that should not be the correct answer since, in the tutorial I was following, the guy used it as private blocking all outside access. The upload of an Images works without issues, so I would roule out any problem with the connection itself, but when I try to delete one I get the error An error occurred (AccessDenied) when calling the DeleteObject operation: Access Denied I was following a tutorial about how to connect the bucket to django. The steps I took: Created a bucket (not public like it said in the tutorial) Created a User Group with "AmazonS3FullAccess" policy Created a User inside the group with both the S3 full access and the "AWSCompromisedKeyQuarantineV2" policy Generated the necessary keys (secret and access) The S3FullAccess policy should be this one: { "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Action": … -
Django Model Inheritance: Every
In Django, I want to have several models of the same type: ANode, BNode, CNode are all of type "Node". In the database, you can look up a "Node" by id, then quickly get what kind of Node it is (ANode, BNode, CNode), and then reference that node. Every node is only of one specific node type, and there are node "Nodes", only "ANodes", "BNodes", "CNodes". There may be many kinds of Nodes (A-Z) each with different fields. I can picture the underlying SQL: there is a "Node" table with an ID column and an enum field keeping track of which type of Node it is. How can I implement that? -
How to let Django serve images when hosting on Vercel
I deployed a Django project on Vercel. The app is responsible for serving data to a Next.js frontend. However, the images don't get served while other data do. GET request to the images return NOT FOUND error after deploying to Vercel. I have studied all similar questions on this platform but none seems to solve my problem. I have this in my settings.py file: STATIC_URL = 'static/' STATIC_ROOT = os.path.join(BASE_DIR, 'staticfiles_build', 'static') MEDIA_URL = '/media/' MEDIA_ROOT = os.path.join(BASE_DIR, 'media/article_photos') I'm serving only the article_photos. I have this in my project urls.py file: urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) urlpatterns += static(settings.STATIC_URL, document_root=settings.STATIC_ROOT) This is the structure of my media folder: I have struggled with this problem throughout the whole day. Any help will be appreciated. Update: This is my vercel.json file: { "builds": [{ "src": "core/wsgi.py", "use": "@vercel/python", "config": { "maxLambdaSize": "15mb", "runtime": "python3.9" } }, { "src": "build_files.sh", "use": "@vercel/static-build", "config": { "distDir": "staticfiles_build" } }], "routes": [ { "src": "/static/(.*)", "dest": "/static/$1" }, { "src": "/(.*)", "dest": "core/wsgi.py" } ] } This is my my build_files.sh echo "BUILD START" python3.9 -m pip install -r requirements.txt python3.9 manage.py collectstatic --noinput --clear echo "BUILD END" Update 2: Below is the error returned: … -
Python Django and parallel process
I'm making a delayed messaging service in Django. I reached the task manager. In theory, it should be launched in parallel with Django, its task is to “read the database” and send messages. I used "multiprocessing Pool", the code was entered into manage.py. It confuses me that when starting, one of the processes fires twice, “ok” in the screenshot. Using a parallel process, the site is assembled and works properly. why is that? Are there any better practices? Result: не ok не ok Performing system checks...

Django Filter a Queryset based on Prefetched FK Relationsship
I have 2 models below, and I am trying to run a query on JournalLineItems that filters out entries that have no associated GeneralLedger entry.

When I try this, the query is not right: JournalLineItem.objects.filter(general_ledger=None).prefetch_related('general_ledger') or JournalLineItem.objects.filter(general_ledger__is_null=True).prefetch_related('general_ledger') -

Make dynamic imports of ts module absolute path in js using Webpack
I'm using Webpack as a bundler. My project contains .ts files with dynamic imports. And everything works just fine. But It is Django project and compressor doesn't see modules to which path is build dynamically. Is there a way to make webpack not build path to module but put it as full string in .js file? This is how it looks now: const obj = await import('../components/MyComponent/MyComponent'); In bundled js: const e = await r.e(3802).then(r.bind(r, 73802)); It is building a path to this module. And I would like to have it as an absolute path. Is there a way to do so? -
Django increment string value without race condition

How to display multiple video streams in django from streamlit?
I have a code that should show a video on a django page. I’m trying to convert it from streamlit to django, but without success. Please tell me how to implement this?

Request data Modifiy in django
I have a class with APIView, which accept request. from there, I pass the request to 2 different methods, but when I print data from 2nd function, it is modified by first method. Sample class events(APIView): def post(self, request): data = request.data self.tinybird(data) self.events(data) I was expecting to have same copy of data in both method, but tinyBird method changes one line as del product['options'] and due to this I am not able to get product['options'] in events() method. As I am passing data separately to both functions, how data modification of 1st function affect data of 2nd function. Tried I tried to send copy of request to each function or one function but still same issue. data1 = request.copy() data2 = request.copy() self.tinybird(data1) self.events(data2) still data2 throw keyerror on data2['options'] -
Django tables2: Table reverts to previous value
I have a view where i display 2 tables and I have a form to create a new filter in my template. Using my code I would expect that the filter table to update and stay that way. However, after creating a new filter, it displays in the table but if i refresh the page or create a new filter, it reverts to the "original" table i.e. if i have 1 filter and I create one but i refresh the page or create a new filter afterwards, the table displayed will show just one filter.

Use Absolute URLs for wagtail richtext

Django template error after parenthesis added by autoformat
I use VSCode and the Django Template Support extension for autoformatting templates. It adds parentheses to my code making it not work. before: {% elif n > page_obj.number|add:'-5' and n < page_obj.number|add:'5' %} after: {% elif n > (page_obj.number|add:'-5' and n < (page_obj.number|add:'5')) %} Template error: In template N:\Coding Projects\poc\templates\poc\product_list_grid.html, error at line 133 Could not parse some characters: |(page_obj.number||add:'-5' 123 : <a class="page-link" href="?page=1" aria-label="First"> 124 : <span aria-hidden="true">&laquo;</span> 125 : <span class="sr-only">First</span> 126 : </a> 127 : </li> 128 : {% endif %} 129 : 130 : <!-- with filter and pages in between --> 131 : {% for n in page_obj.paginator.page_range %} 132 : {% if request.GET.item_code or request.GET.brand__brand_name or request.GET.description %} 133 : {% if n == page_obj.number%} 134 : <li class="page-item active"> 135 : <span class="page-link"><b>{{ n }}</b><span class="sr-only"></span></span> 136 : </li> 137 : {% elif n > (page_obj.number|add:'-5' and n < (page_obj.number|add:'5')) %} 138 : <li class="page-item"> 139 : <a class="page-link" href="{% update_url n 'page' request.GET.urlencode %}">{{ n }}</a> 140 : </li> 141 : {% endif %} 142 : 143 : <!-- without filter and pages in between --> Is this a formatter issue?

Django + daphne + StreamingHttpResponse return chunked data not streaming data
I am currently developing API using StreamingHttpResponse in Django. As far as I know, StreamingHttpResponse is supposed to output results in yield units, but in reality, it outputs yield value's' For example, I used generator below. def iterator(): for i in range(100000): yield {"iteration ":str(i)} Then, the result value is expected to have one yield value each time. {"iteration" : "1"} {"iteration" : "2"} ... However, in reality, it returns a certain buffer size(maybe 4000chars), waits, and then returns again. {"iteration" : "1"} {"iteration" : "2"} ~~ {"iteration" : "100"} In order to actually return a value every time without a buffer like above, which settings among django, daphne, and streaminghttpresponse should I add or remove? actual log : 2023-11-10 05:29:58,361 DEBUG 8 --- [MainThread] daphne.http_protocol:283 HTTP response chunk for ['192.168.192.1', 0] --- [7f6f53f9c0a393a547dccbdde2c59065] [24a60a12badf08b6] [user:6549c3c2c8fd4d4d6099d6d1] 2023-11-10 05:29:58,376 DEBUG 8 --- [MainThread] daphne.http_protocol:283 HTTP response chunk for ['192.168.192.1', 0] --- [7f6f53f9c0a393a547dccbdde2c59065] [24a60a12badf08b6] [user:6549c3c2c8fd4d4d6099d6d1] 2023-11-10 05:29:58,398 DEBUG 8 --- [MainThread] daphne.http_protocol:283 HTTP response chunk for ['192.168.192.1', 0] --- [7f6f53f9c0a393a547dccbdde2c59065] [24a60a12badf08b6] [user:6549c3c2c8fd4d4d6099d6d1] 2023-11-10 05:29:58,412 DEBUG 8 --- [MainThread] daphne.http_protocol:283 HTTP response chunk for ['192.168.192.1', 0] --- [7f6f53f9c0a393a547dccbdde2c59065] [24a60a12badf08b6] [user:6549c3c2c8fd4d4d6099d6d1] 2023-11-10 05:29:58,432 DEBUG 8 --- [MainThread] daphne.http_protocol:283 HTTP response chunk for ['192.168.192.1', 0] …
